Memorable Moment Essay

Growing up I’ve had many memorable and important experiences. A lot of these situations have led me to become a better person. I can say that I have had my share of bad experiences as well, but all have led up  to making me the person I am today. One experience that sticks out among them all is one a little over nine years ago. when I learned a valuable lesson. The most memorable childhood experience I have recalled is when I was nine years old. I grew up with my mom, dad, two sisters and a brother. Being the oldest, I always played as a babysitter for my parents .  One day my parents were getting ready to take my brother and baby sister to the doctor. They went through their precautionary measures before they left like ; locking all the doors, windows, leaving their numbers on the fridge, and so on. before walking out the door my dad told me to do my homework and watch my sister. As they left I decided to disregard everything said and not do my homework or even keep an eye on my sister. I started playing Playstation, I got the new Ratchet and Clank game a week earlier and didn’t want to waste any time in beating it. As the day progressed and I was getting further in the game, I started thinking about when my parents were going to get home. So I paused the game for a little to call them. Getting a hold of them was pretty hard considering my parents never answer their phones, but I eventually got through to my mom. During our conversation my mom asked if I did my homework, tensing up and scared to say no, I replied yes, then she asked about my sister. I had no clue where she could be but I again I replied with a hesitant,† y-y-yes mom she’s in her room sleeping†. Already at lie number two, I swiftly rushed to my sisters room. Slamming the door open in urgency, I quickly scanned the room for any sign of my sister. nowhere to be found, I yelled out â€Å"CELINE! † multiple times. Getting no response, I ran down stairs hastily in search for my sister, thinking about the worst possibilities. Coming to a conclusion she’s not in the house, I hurried to the backward. seeing no sign of her I decided to get my shoes on and go outside. ith still no clue to where she could be, I started knocking on the doors of my neighbors and asking in desperation. ironically my aunt lived a couple houses down, and when I asked her she got a little worried, and replied â€Å"no, why?! Is everything alright?! â€Å". I answered with a simple â€Å"yeah khalte, every thing is good. My mom said she was going to bring Celine over to play with Zeinab and I was wondering if she was still here. â€Å". Lie number three. My aunt being her usual self called my mom as soon as I left, to see what was really going on. Heading back home a while later I saw three missed calls from my mom and I didn’t know what to do, what to say that would get me out of this day trouble less. I called my mom back, wasting no time she started questioning me and asking about my sister. I told her everything was fine and it was just a misunderstanding, lie number four. she bought it, but said they are leaving the doctors. running around frantically I didn’t know where to look and what to say to make this all end. making another round through the house, I noticed my parents just pulling up. y dad walked in first calling my name. I threw in the towel, with nowhere to turn and no one to blame but myself, I went to my dad crying. Taking none of it, he asked â€Å"where is Celine? â€Å", not being to answer with a definite answer I told him, â€Å"I don’t know where she could be baba, I looked everywhere†. Yelling at me for being so irresponsible we both started looking for while my brother, s ister(Adina), and mom were just walking in. my dad went straight to the second floor, looking through room after room, closest after closest, with no luck. On our way down the stairs we saw my baby sister in my mom’s hands sleeping. Awed in belief, I asked my mom where she found Celine? She answered with a calm, â€Å"under the kitchen table†. My dad asked, why I seemed so worried, if I was supposed to have everything under control. Explaining to him, I lied to mom and that I’m really sorry. He then asked if I finished my homework, seeing what the lies did to me before, I answered with an honest, â€Å"No Baba†. He then told me, â€Å"yallah baba, finish it so I can take everyone out to get some ice cream†. This has become a life lesson and an important milestone in my childhood. Up until this point I would lie unconsciously to get my parents, teachers, friends off my back. Thanks to this experience I stopped all the unnecessary lieing. Realizing that first lie I told my mom was putting my sister in jeopardy and not my self. If something had happened to her I would never be able to live that down. that’s why I have tried to implement a strict â€Å"No lying† policy in my life. This is only one of the many memorable experience I have had from my childhood. All making me the man I am today.

Care Connect Commit

Care Commit Connect Introduction Problem Statement In the united States of America, people have access to best oral care. There are standards and protocols imposed on dental business. Yet, millions of people in America do not get basic dental care or they end up getting over treatment. Private equity firms own most of the dental businesses. Dental business is one of the most profitable businesses. Dental business owners are top 1% earners In united States. Management puts a lot of pressure on dentists to produce more.The primary goal for management and dentists has become finding loopholes with insurance and aximizing production. unnecessary and over-treatment have become a common practice. Dental treatment Is expensive. We serve a low income area and most patients cannot afford it. We have been providing dental services over 30 years. We are in the health care business, and we need to ask ourselves, are we doing justice with the profession? Are we responsible if patients do not rece ive proper care? what should we do when the patient cannot afford the treatment?How much should we trust patient's finances? Outcome and Performance Currently, staff and doctors get paid based on office production. Indirectly we are encouraging staff and dentists to base patient care on production. Patient care should be the company number one priority. Patients are not comfortable to visit a dental office. One of the main reasons Is the cost and overtreatment. We are not a non-for-proflt organization. We have to balance between patient care and business. Ideally no patient should leave the practice untreated for any reason.We need to set an example to other business by exercising a morally correct approach and still be 1 OF3 good business name. We need to work on the company philosophy and take it to the ext level and have a global outcome. We sell happiness by enhancing people's smiles. Structure In order to do Justice with the profession everyone needs to understand the need of i t. What exactly are we doing wrong? Where is this leading the society? We should be ready for a change. There will be a lot of changes in the organization.We can implement the proposed solution conveniently step by step. We adhere to the dental code of ethics. We do not do wrong treatments or do over billing. The professional dental code of ethics does not define moral ethics. We need to create a code of ethics ased on the company philosophy. Moral ethics differ from culture to culture. First, we need to incorporate moral virtue. We can achieve this by offering classes and making it mandatory for everyone and we can offer CE credits. Second, we should change the compensation structure for everyone.The compensation should be based on salary rather than commission. The performance evaluation should be based on the number of patients seen and patient satisfaction. Patient charts should be audited every day. We should present an affordable treatment plan to every patient we see. The tre atment plan should not address Just the patient's chief complain, rather it should provide a complete solution. Patient care should not be an option; it should be mandatory. Third, we should advertise the company moral philosophy to attract more patients. We can offer free patient consultation.We should have a sliding fee structure for patients who cannot afford expensive dental treatments. Emphasis should be put on patient education; we can set up camps and school visits and take part in the local community affairs. Finally, we should change company hiring policy. We should make community experience a requirement for any position. Representation of Data The success of the project can be measured through conducting surveys. Every patient should be encouraged to fill out a survey. Currently, we have approximately 10,000 active patients.Every month we should discuss the practice analysis report. We should do a comparison with last year's data. When we offer free patient consultation w e might be losing some revenue, but there should be a significant increase in comprehensive dental procedure revenue. Overall revenue should increase. When we start seeing more patients, company expense will not increase we can compare previous year's expense sheet with current. We should have 360 feedback forms every three months, in which every employee should be able appraise other employees.Every patient referral report should be analyzed periodically. We should be able to see the difference in patient count through word of mouth. Methodology and Findings Theoretical and Empirical Evidence Providing health care is a noble profession. Oral health is an essential part of overall health. Dentists are doctors who help patients maintain their oral health. In the United States of America, the healthcare business is one of the most profitable businesses. Government cuts of benefits for adult patients make it difficult for patients with low income to maintain their oral health.There are remarkably few dentists to provide comprehensive treatment to patients. Every profession comes with responsibilities. Dentists that chose dentistry as a profession should provide complete care for patients and should be held responsible. It comes down to moral virtues of a dentist to provide a complete solution to patients based on their financial ituation which might be compensating fewer. This cannot be taught to a person they have to be caring habitually. It is necessary for a dentist to be morally right in order to care, commit and connect toa patient.We have to take ownership and responsibility to make the society morally correct. We will have a good name for business. We have to become a role model for the society. This solution will help us attract more patients by providing honest, comprehensive and less expensive treatments. We can approach Federally Qualified Health centers, in order to provide omprehensive services irrespective of the patient's ability to pay. Some denta l offices are integrating with Federal Qualified Health Centers, a few dentists set up dental camps with free consultation periodically and try to educate patients.Many solo practitioners have lowered their fees to be able to see patients with low income. Many offices have tried reducing expense in order to able to see patients at low cost. Comparison with Other Methods Some of the other alternate solutions could be integrating with federally qualified health centers which will take a lot of time, allocating budget every year for delivering ree treatment to qualified patients, performing mobile dentistry with proposed companies approach and starting in-house insurance programs.Conclusion and Recommendations Limit and Scope of System We can implement the proposed solution at one location; within one, year we should be able to see the difference in the company's financial report. We have to take ownership and Judge the patient's honesty. Maximizing the location's capacity will increas e revenue and we should be able to cover the cost. References Heath, D. , Rosenbaum, J.

Autoclave Essay Example | Topics and Well Written Essays - 500 words

Autoclave - Essay Example The relationship between temperature and pressure is a directly proportional one. In chemistry when the pressure of a gas rises, the temperature of the gas increase correspondingly too. With this principle in mind steam is a gas used in the autoclave chamber. Increasing its pressure in a closed system will lead to increase in temperature. At higher temperatures water molecules of the steam become more invigorated. At this vigorous speed the molecule’s penetration escalates. This principle proves to be advantageous because it reduces the time taken by the things in the autoclave to sterilize (Hussain, 2009). As mentioned above dry heat and moist heat can both provide sterilization but they differ in some manners. Dry heat accounts on oxidizing molecule for its action. Dry heat’s mechanism of action is slower than moist heat. Dry heat penetrates walls of substances much slower than moist heat. Dry heat is used in sterilizing glass products, oils and powders. Due to its slow mechanism of action sterilization by dry heat is done at 171 degrees centigrade for 1 hour and the time may increase depending on volume. Dry heat may also be used in the shape of an open flame used to sterilize inoculating loops, mouths of pipettes and culture tubes. On the other hand moist heat destroys organisms by the denaturing proteins and also by disrupting the membrane of lipids. Moist heat is favored because of its penetration powers. It is known that the most resistant spores require a temperature of 121Â °C for around half an hour to denature. Hence moist heat application is more effective compared to dry heat sterilization. This can also be proven by the fact that moist heat, sterilization can be completed at lower temperatures in lesser time. Culture media, flammable and heat-sensitive items, liquids and dense loads can be sterilized by moist heat (Black,

Human Resources Management in Apple Company Essay

Human Resources Management in Apple Company - Essay Example Microsoft was the prominent competitor of Apple from tis beginning itself. In 1980’s and 1990’s Apple struggled to counter the competition faced from Microsoft. Microsoft pushed Apple yards behind with the introduction of their Window based operating system. However, Apple was able to bounce back at the beginning of twenty first century with the help of their innovative â€Å"i† series products such as iMac, iPhone, iPad, iPod, iTunes etc. Kim (2010) has pointed out that Apple Inc, is currently the second largest company in the world in market capitalization, second only to Exxon Mobil. Moreover it is believed to be the most valuable technological company in the world at present, again pushing Microsoft far behind (Kim, 2010). (Warren, 2010) Even though Apple succeeded in achieving top spots in international market, many people believe that their organizational culture and human resource management needs drastic changes to maintain their top spot in the market. E ven though Apple employees are getting competitive salaries, increased workload, lack of work-life balancing, lack of motivation, prejudices and biases in deciding promotions etc are some of the major complaints of the employees. Moreover, Apple’s success and failures revolve around the charismatic leadership of Steve Jobs. This paper critically analyses Apple’s human resource management policies at the individual level, group level and organizational level. Individual Level Work Motivation The topic of employee motivation in Apple Company is a controversial one. On one side, Apple is able to motivate the employees and on the other side some of its HR strategies are demotivating the employees. It is a fact that Apple provides ample opportunities to the fresh employees to grow under the wings of experienced employees (Qumer, 2009, p.3). The above strategy is a big blessing for the fresh employees to take advantages of the immense experience and talents of the experience d ones. The above work culture helps Apple to blend fresh and the experienced hands in a judicious manner so that neither the employees nor the organization faces any problems in completing their works. Fresh employees may bring new ideas to the organization which will be critically analyzed with the help of experienced ones. Thus the fresh people will get immense support from the experienced hands in shaping their ideas and concepts useful to the company. The compensation and benefits offered to employees of Apple are very competitive and it includes product discounts, vacation time, healthcare, training courses, casual dress codes on jobs etc. In 1995, Apple created the Apple Fellows Program in order to recognize its best employees who had made extraordinary contributions to the company. Funny, brilliant, relaxed co-workers and modern spacious beautiful offices filled with comfortable equipments etc are some of the major benefits of working in Apple Company. Apple workforce includ es diverse employees from different countries which enable them to utilize the expertise from different regions. It provides equal opportunities to its diverse employees irrespective of their ethnic background (Qumer, 2009, p.3-9). In short, Apple is keen in recognizing outstanding performances with rewards which is definitely a motivating factor for the employees. At the same time there many complaints also about some of the controversial HR policies of Apple. Employees often forced to work overtime and thereby they are facing troubles in achieving proper work-life balancing. Moreover Apple provides no information about the new products which are going to be developed in the company. The above policy demotivated the employees since no organization can capture the employee

Thread - Assignment Example Thus, America was observed as a function of consciousness by the Frontiers (Shames, n.d.). According to Shames, America’s frontier provides opportunity and hence, brought the concept of more in order to bring about optimism and retain economic boom. Similarly, the typical consumer behavior suggests of engulfing more satisfaction. The greed for more beyond the satisfaction level of the consumers leads individuals and organizations of the country to be over ambitious for the achievement of goals and objectives. However, this over ambitious nature also leads to the creation of attitude amid people of the America. They had a notion that there is no worst thing than losing. Additionally, they developed an attitude of obtaining the optimum output from every resource (Shames, n.d.). Shames termed 1980s â€Å"an era of nostalgia† because prior to that period the young urban working people were considered as money-oriented. The sole motive of the people of America was that money is the ultimate requirement for them. Also it is to be noted that because of the greed for ‘more’ people did not adapt to e other values and desire that are essential for human being. People were less conscious of the personal lives and his/her social responsibilities. However, in the 1980s the people realized the importance of the social life through spending times with friends and family members. Moreover, in that era the coinage of the two terms namely, ‘hippie’ and ‘yippie’ was done. Thus, Shames rightly termed 1980s as â€Å"an era of nostalgia† (Shames, n.d.). Shames was ironical about the concept of ‘more’ from the American people. This is because he has been observing the people of America to be more inclined to the concept of ‘more’. The people in that period were so busy in their professional work that they had forgotten the social need and responsibility of every individual.

Globalization_Integrative_essay - Essay Example Robinson and Amartya Sen respectively. William Robinson argues, â€Å"Scholars and activists have tended to underrate the  universal nature of the dynamics involved in globalization that is redefining all the basic reference points of human community and social evaluation, and needs a modification of all existing patterns.   In the systemic dynamics which are driven by and that drives globalization, we are gradually witnessing an international conflict between capital and poor labor force in the South,  and  a labor force that is being proletarianised in the North. Robinson argues that this divergence is incubated via and worsened by technologically mediated novelties in capitalist production procedures that gradually discipline labor.  Disciplinary activities   comprise: threats of outsourcing; enforcing dynamics to terms of employment; employing technology and competence in production to drive down wages; privatization or attrition of social welfare; the employ of technology to supervise the work; and grad ually deflationary economic laws that attack standards of living for all-bar social elites. For Robinson, the means through which international capital is hatched out of state capitals in the global North is the main theme of globalization. He sees an effect in the capture by international elites of the state equipment for control in the global North and the effort to do so in the global South. He continues arguing in a  discussion paper  that in realizing the procedure of capitalism in its neoliberal phase, and in shaping reactions to it, it is critical to evaluate how  globalization is â€Å"a qualitatively new international stage in the on-going development of world capitalism†. This backs  Ellen Meiksins Wood’s view that we are living at a time when capitalism for ones has become a real universal system. Capitalism is worldwide also in the feeling that its logic – the logic of accumulation, profit-maximization, commodification, competition – has

Attendance Requirement in College Essay Example for Free

Attendance Requirement in College Essay Attending college is supposed to signify freedom to make choices regarding education. However, many students who plans to continue their education realize that college does not give this freedom. In some countries, college students are expected to attend classes that they have register. However, should attendance be mandatory in college? Even though some believe that college attendance should be flexible, I believe that college attendance should be mandatory. The first reason why college attendance should be mandatory is the lack of understanding. For example, Students who attend regularly classes have better opportunity to understand the courses what are done in class, while students who do not attend classes will not understand. Also, because students who attend regularly the classes understand the courses, they have a better chance to have good grades during test. On the contrary, students who do not attend classes, and do not understand the courses; they get bad grades during test. Indeed, college attendance should be mandatory to help all the students understand the courses. Another reason why college attendance should be mandatory is it build relationships. College attendance build relation between students and students. In college, there is many ways to meet friends that you can count on in the future such as joining a club, or in class. Students who do not attend college classes will not have these opportunities. College also build relation between students and teachers. Students who attend classes have the opportunity to know their teachers. Teachers have the same opportunity to know their students, and that relation between them will help the teachers to know the students’ lacks and find ways to help them. On the other hand, students who do not attend school will be stuck with his lacks. Opponents believe that mandatory attendance policies does not go under life lesson categories. If students do not show up at the classes, they register that will not affect them in the real world. However, I believe it does go under life lesson categories. If students get into the habit of not showing at classes, they register that will affect them in the real world. For example, if you do not show at work, you will be fired. College attendance should be mandatory to avoid that habit. In conclusion, College attendance should be mandatory to help students understand their course, to build relationship between students/ students and students/ teacher and to avoid bad habit. Nowadays, many students are skipping classes. In my opinion, college attendance should be mandatory.

Development of Soil Nutrient Sensors

Development of Soil Nutrient Sensors The rising demand for food crops and the growing concern for environment have made it necessary to shift from traditional agricultural practices towards modern agricultural practices. Traditional agricultural practices are labor intensive, time consuming, expensive and also a cause of environment pollution. To achieve sustainable agriculture, it is necessary that the precision agriculture technologies and practices are integrated with the traditional practices, which will also help to deal with the spatial heterogeneity of the soil [1]. The biggest hurdle in the proper implementation of precision agriculture is the inability to generate information related to a particular site rapidly and at an acceptable cost using laboratory analysis and soil sampling methods. The nutrients required for the healthy growth of a crop are obtained from the soil. The quality of crop yield depends on the quality of soil in which it grows. Therefore, soil testing is an important aspect of precision agriculture. The proposed research work is an effort towards the design and development of a soil monitoring system that can be used to estimate the urea content in soil. The system makes use of Partial Least Squares Regression Technique (PLSR) for the estimation of urea. The system can be made portable, smart, low cost and user friendly through the use of embedded systems. With some modifications the system can be designed to estimate more than one soil component. The thesis is organized in the following chapters as described below. Chapter I (Introduction) â€Å"Agriculture not only gives riches to a nation, but the only riches she can call her own†[2]. The growth in the demand for food, feed and fiber globally is anticipated to grow by 70 percent. The demand for crops for industrial use and in the production of bio-energy is also expected to rise simultaneously. The increasing demand for agricultural goods will put huge pressure on the limited resources available. The increase in urban settlement areas will force agriculture to compete for land and water. Agriculture will therefore have to adapt itself to newer conditions and at the same time will have to address issues related to climate change, maintenance of biodiversity and preservation of natural habitats [3]. To meet these demands, farmers therefore need to equip themselves with new technologies so as to increase productivity with limited number of resources. Sustainable resource management is the need of the hour. Conservation of soil quality is crucial to sustainability in agriculture. This has led to a shift from the use of traditional agricultural practices to modern agricultural practices so that the available resources are utilized in a sustainable manner. The modern technique of farming known as precision farming is based on the concept of site specific crop management. This method takes into consideration variability exhibited by the soil and accordingly inputs are applied based on the local requirements within a field. Soil sensing plays an important role in precision farming. Large numbers of soil sensors are being developed all around the world to measure different soil properties. Some of which are still in the research and development stage and some of which are commercially available. Based on their principle of working these soil sensors can be classified as follows: Electrical and Electromagnetic sensors: Depending on the composition of soil under test, electrical capacitance or inductance, resistivity or conductivity of the soil is measured. The response time of these sensors is very fast, they have high durability and are of low cost. These sensors are commercially available. Optical and Radiometric sensors: These sensors, through the use of electromagnetic waves, measure the level of energy that is either absorbed or reflected by the soil particles depending on the soil composition. The properties of the soil are measured using visible and near-infrared wavelengths [4]. They can be used for the estimation of CEC, soil texture, moisture and other soil parameters with the help of appropriate data analysis techniques. Mechanical sensors: these sensors measure soil resistance with the help of a tool used in the soil. The measure of resistance offered by the soil has a relation with the compaction of the soil which is a spatially varying property of soil. Acoustic sensors and Pneumatic sensors: Though these are a class of mechanical sensors, they can be used as an alternative means for the differentiation of physical and mechanical characteristics of soil. Measurements taken using pneumatic and acoustic sensor have been used to correlate soil texture and compaction. The application of acoustic sensors in characterizing the physical state of soil is not very clear and requires more research work. Electrochemical sensors: These sensors produce an output voltage through the use of ion selective membranes, depending on the activity of ions under study such as H+, K+, NO3 −, Na+, etc. Soil pH sensors using this technique are already commercially available. The extraction of ions such as potassium in real time is still not possible even though the concept appears to be simple. There is a need to develop fast, real time and portable soil sensors which can generate soil report instantly. Thus, the problem of designing and developing a smart soil monitoring system was formulated using a reconfigurable embedded system platform. Chapter II (Literature Survey and Objectives) The conventional laboratory methods of soil testing have a number of limitations such as they are expensive, labor intensive and time consuming. As such new methods of soil testing are being developed across the globe. A number of soil nutrient sensing techniques are in the stage of development and testing. These sensors can be broadly classified into two types depending on the techniques of measurement being used. 1. Optical sensing uses reflectance spectroscopy technique wherein the light that is absorbed/reflected by soil particles is measured. Since optical sensing techniques have the advantage of being non-destructive they are more widely used as compared to electrochemical sensing techniques [5], [6]. Soil color analysis can be used for estimating soil organic matter content through the use of optical sensors [7]. The visual and near-infrared spectral reflectance in optical sensing can be used for estimating soil texture, moisture, CEC etc. [8]. 2. Electrochemical sensing is based on the measurement of current or voltage generated between the sensing electrode and the reference electrode. The amount of voltage or current measured is related to the concentration of the selected ions such as H+, K+, NO3-, etc. [8]. Ion selective electrodes made of glass or polymer membrane, or ion-selective field effect transistors are used for the measurement of soil fertility. Ion-selective membrane sensors have a huge potential in the development of on-the-go soil nutrient(s) and pH sensors [9]. Currently, the accuracy of the results using these sensors is low as compared to those using laboratory tests, but this can be taken care of by increasing the sampling density. Use of Spectroscopic techniques in the estimation of soil properties has been demonstrated since 1970’s [10]. Various methods using spectral analysis have been proposed for the measurement of the soil properties. Methods that are based on the physical and analytical characteristics of the signal and chemometric based empirical methods provide good effective predictability. Therefore, the relation between soil properties and soil absorption can be used to develop regressions using field and laboratory data for calibration. Spectroscopic techniques are found to be faster, can provide real time measurements and are of low cost, as compared to conventional methods and hence are found to be more suitable when there are more samples and analysis to be done. Also, unlike laboratory testing methods which require sample pre-processing and the use of chemical extractants, spectroscopic techniques can be used directly, thus saving on cost and time [11]. Thus, the problem of developing a soil nutrient sensor using RF spectroscopy based on the dielectric principle was formulated. The thesis emphasizes on the design and development of the sensor and the use of embedded platform to make it portable, real time and user friendly system through the use of DSP algorithms. Objectives: In order to meet the global requirements of increased crop productivity and sustainable agriculture, there is an urgent need of developing soil sensors which are fast, accurate and portable. Also, the problem was formulated keeping in mind the conditions of Indian farmers. Indian farmers are mainly small farmers who are poor, technically unfit and cannot afford modern tools. This research work is being undertaken with the main objective of developing a fast, portable, cost effective and user friendly soil monitoring system to analyze the fertility status of the soil. The objectives of the research work are the design of a dielectric cell to measure absorption loss at RF frequencies for various soil nutrients and to use this RF data to develop a FPGA based smart soil monitoring system for accurate prediction of soil content using PLSR technique. The system shall be user friendly as well as reprogrammable for changed environmental conditions. Chapter III (System Design for Soil Monitoring System) The block diagram of proposed design for Soil Monitoring System is as shown in Figure 1. The design consists of RF data obtained from Scalar Network Analyzer fed as input to Altera DE2 board with target as NIOS II FPGA. The RF data is obtained from the soil sensor connected between a tracking generator and a spectrum analyzer. A soil sensor based on the dielectric loss technique is designed and constructed to measure the RF responses of various soil nutrients. The cell is rectangular in shape with outer dimensions 13cmx2cmx2.5cm and is made up of PMMA sheets. The inside surface of the cell is lined with gold foil and the same is connected to the outer shield of the feed connectors so as to provide the necessary shielding effect. The outer surface of the cell is covered with a copper foil and is also provided with the necessary shielding effect. A wire made of gold is connected from the input feed connectors to the output feed connector at centre of the cell. The RF spectrum of a sample is measured by placing it in the cell. A tracking generator is used for injecting an RF signal into the sample through the central gold wire. Thus, a dielectric cell consisting of the central wire, the outer copper shield and the sample is formed. The signal strength starts reducing as it propagates through the central wire from the input end to the output end of the cell, due to the dielectric loss associated with the sample solution. Thus, an output signal proportional to the absorption loss of the sample solution is captured by the RF spectrum analyzer connected at the receiver end of the cell. Signal Hound USB-TG44A tracking generator and Signal Hound USB-SA44B spectrum analyzer are used with both the instruments working in the frequency range of 1Hz-4.4GHz. Figure 1: Block diagram of the Soil Monitoring System Figure 2 shows the RF spectra for urea in the range 10MHz to 4.4GHz. Figure 2: RF Spectra of urea. Figure 3: Section of urea spectra with varying concentrations Samples for obtaining the RF responses of various soil components are prepared by dissolving the required component in distilled water. The amount of the component to be added to water was calculated from the data obtained from agricultural department. This amount was taken as the normal concentration of a particular component found in the soil. Samples of varying concentrations of the soil components are prepared and denoted as 1 for normal, 0.5 for half the normal, 2 for twice and 3 for thrice. The soil components considered for the study are urea, potash, phosphate, calcium carbonate and sodium chloride. The frequency range of 10 MHz-4.4GHz is divided into smaller frequency ranges based on the unique frquencies at which the variation in the attenuation is found as per the change in the concentration of the soil component. A set of recorded spectra for various combinations of the five soil components with concentrations ranging from 0.5 to 1.5 are used in the calibration file. In order to predict the unknown concentration of urea in a sample, the detected spectra containing the urea signature along with the other components is passed through signal conditioning stage. The output from Spectrum Analyzer is stored in the computer. This data is then fed to a CYCLONE II device with Altera Nios II processor running on it. The recorded spectra are then passed through SIMPLS algorithm running on NIOS II processor. The algorithm predicts the concentration of unknown sample (Urea) and displays the result on LCD or a computer screen. The SNR of the detected spectra must be sufficiently high so a s to provide reliable urea specific information and therefore data processing is needed to identify spectral features of urea from the combination spectra originating from interfering matrix components like potash, phosphate, sodium chloride and calcium carbonate. We can extend the use of this system for the analysis of other soil components by modifying the processing algorithms required to analyze that component without changing the hardware. Chapter IV (Multivariate Data Analysis) It is a statistical analysis technique used in the case of data consisting of multiple variables. Due to the advancements in the field of information technology there is a huge amount of data being generated in various fields. Though the magnitude of data available is huge, it is still a challenge to derive useful information and knowledge from this data. Multivariate Analysis can be used to derive meaningful information for the improvement of process performance and product quality. Over the last decade, multivariate analysis is being successfully used to monitor and model chemical/biological processes [12]. Techniques using multivariate data analysis are widely used in the analysis of spectral data both quantitatively and qualitatively. Quick analysis of complex samples from their spectral signatures can be done using standard tools like Partial Least Squares (PLS), Principal Component Regression (PCR), Principal Component Analysis (PCA), Multivariate Curve Resolution (MCR) and discriminant analysis based on chemometric techniques [13]. Partial least squares (PLS) isone of the recent multivariate data analysis technique particularly useful in situations where there is a large set of independent variables (i.e., predictors). A set of dependent variables can be predicted from this set of independent variables by using PLS. Partial Least Squares (PLS) can be an effective tool for the analysis of data as it has minimum constraints on scales of measurement, size of sample, and residual distributions. It consists of methods for regression and classification, and techniques for reducing dimens ion and tools for modeling. The basic assumption on which the PLS methods work is that a small number of latent variables that are not directly observed or measured are used to drive the observed data from a process or a system. The technique of PLS for projecting the observed data to its latent structure was developed by Herman Wold and coworkers. PLS is now being used as a standard tool in the analysis of a wide spectrum of chemical data problems in chemometrics. The successful data analysis of PLS in chemometrics has led to its increase use in other scientific fields such as bioinformatics, food research, medicine, pharmacology, social sciences, physiology etc. PLS is a multivariate technique that transforms the input-output data onto a smaller latent space, by extracting a small number of principal factors having an orthogonal structure. The extraction of the factors is done in such a way that it provides maximum correlation with the dependent variable [14]. To model linear relations between multivariate measurements, PLS is used as a standard tool. Multivariate Calibration Model for Soil Monitoring System: Multivariate spectroscopic data can be analyzed using the PLSR model. PLSR is one of the techniques of multiple linear regressions and is probably the least restrictive of the various multivariate techniques used in multiple linear regression models. This feature of PLSR makes it possible to be used in situations when there are limitations on the use of other multivariate methods, for example, when the predictor variables are many as compared to number of observations.PLSR can be used as an elementary analysis tool for the selection of suitable predictor variables and in the identification of outliers. PLSR model based on SIMPLS algorithm using C language is developed and ported on NIOS II platform to estimate the urea concentration. The PLSR model is validated for the following cases: Case 1: Changing urea concentrations from below normal to above normal i.e. from 0.5 to 2 and keeping other components at their normal concentration value i.e. 1. Case 2: Changing the concentration of each of the other soil component from 0.5 to 2 and keeping urea constant in all the cases. Chapter V (Design of FPGA Soft Cores for Soil Monitoring System) DSP functions can be implemented using two different types of programming platforms: digital signal processors (DSP) and field programmable gate arrays (FPGAs). Digital signal processors are microprocessors specifically designed for handling DSP tasks, while FPGAs are reconfigurable signal processors. The factors that make FPGAs more suitable, particularly for high performance computing applications are: (i) Huge potential for implementation of parallelism (ii) The control logic is embedded (iii) On-board memory in FPGA helps to overcome the limitation set by number of I/O pins on processor logics memory access bandwidth and hence results into significant performance benefits (iv) A higher capacity FPGA can be used on the same board as an older device, to support performance upgrades. DSP Implementation on Embedded system The implementation of DSP algorithms is done on Altera platform. A Nios II system is designed to measure the concentration of urea in soil. The Nios II system is the heart of the instrument which controls the various modules of the system like interacting with 12 bit ADC and performing the SIMPLS algorithms on the spectral data to estimate the concentration of urea. The whole interface and algorithms are implemented using 32-bit NIOS II soft-core ported on CYCLONE II FPGA. Chapter VI (Analysis, Results and Conclusion) The thesis covers the design and development of soil sensor based on the dielectric technique. The technique proposed the use of RF signals in the range of 10MHz-4.4GHz and analyzing the detected spectra in the soil sample for urea signature. In this thesis a novel Soil Monitoring System is developed using RF spectroscopy based on embedded technology. An Altera DE2 board based on NIOS II soft-core platform and having target as CYCLONE II (EP2C6) is used to estimate the urea content in soil in the RF range of 10MHz-4.4GHz. SIMPLS algorithm for PLSR model is developed using C language and embedded on the NIOS II platform for the estimation of urea concentration. The designed sensor was tested for its precision by recording the spectra of a particular component over a number of times. The PLSR model was validated by calculating percentage error under various conditions. It was found that the predicted urea values showed percentage error which was within the acceptable levels required fo r device development.

No Title :: Olivia Essays

No Title The lines selected for analysis are from act V, scene I, lines 115-129, when Orsino is talking to the love of his life, Olivia, about dueling with the love of her life, his servant Cesario (who is actually lady Viola in disguise, and who is secretly in love with Orsino!). From these lines I find Orsino to be a bitter, jaded, jealous man whose mindset is revenge against the woman who has played with his heart, bruised his feelings, and never returned his undying love, and the man who stole his woman away from him (though she never really was his). In these lines the reader can hear a change in Orsino’s voice—and in his mind. He feels betrayed by the one who was supposed to be loyal, and is now using a take-no-prisoners ideal to this duel. He feels Cesario will get what’s coming to him—how dare he let the woman his master is in love with fall in love with him?—though Cesario had vehemently denied Olivia’s advances. Orsino is blinded by thi s unnecessary and displaced anger towards Cesario, and firing terrible threats and promises to the woman he loves about the man she loves. He can’t see that Olivia is as unhappy as he is, because the one she loves doesn’t love her back. He sees her only as a tease who strings men along for years with no intention of being in a relationship with them. He doesn’t realize that his vicious actions will push her further away, rather than bring her into his heart—which is what Orsino is ultimately striving for. Ten points for psychological depth: 1. â€Å"†¦savage jealousy†¦Ã¢â‚¬ : these are biting words—â€Å"savage† shows that it is more than just immature, childish jealousy. It’s real, hard, nasty jealousy that could escalate to more than brooding and sulking in one’s room about it. This shows Orsino to be extremely emotional—when the one he loves is infatuated with someone else, and someone so close to him he doesn’t take it lightly. 2. â€Å"†¦savors nobly†¦Ã¢â‚¬ : there is some sick pleasure in enjoying what he is about to do. He can enjoy injuring or killing Olivia’s love, but he’ll make sure to do it with some grace. I think Orsino would see it as some kind of release—the ultimate punishment for the man who was supposed to be his servant and obey him forever.

Larry Summers Memo :: essays research papers

Larry Summer’s Memo   Ã‚  Ã‚  Ã‚  Ã‚  A controversy exists whether the World Bank should be encouraging migration of dirty industries to less-developed countries. Larry Summer challenges that the World Bank should persuade such a migration. Others contend that these less-developed countries, despite their economic plight, should not be coerced into harboring dirty industries, a position I support. (A1) In his first argument Summer wants to force a sudden increase in pollution, which would cause an improvement in the economy, of lower wage countries. Summer justifies his beliefs by giving an example of circumstantial as hominem. He states, â€Å"Health impairing pollution should by done in the country with lowest cost, which will be the country with the lowest wages.† An assumption is made by Summer, where he concludes that lowest cost countries will have the lower wages. He concludes by saying, these low wage countries should contain high pollution. The premise of Summer’s argument is assumed true, so his argument is invalid, but strong.   Ã‚  Ã‚  Ã‚  Ã‚  (C1) Many agree with Summer on his stance of high-pollution industries in lesser-developed countries. They claim that it is economic logic to fill the countries with low wages with profitable industries. By doing this, it would cause more people to want to live in a less populated area and work for higher wages. A sudden increase in population would also increase the number of the labor force. By doing this, more workers and industries would rapidly affect the growth of the economy.   Ã‚  Ã‚  Ã‚  Ã‚  (R1) In closing the first argument Summer commits to subjective fallacy when he states dumping toxic waste is â€Å"logical† and â€Å"impeccable†. He develops this argument by using errors in reasoning, such as these examples. Summer also makes ambiguous claims by make a personal attack on the reader. The phrase â€Å"we should face up to that† tells the readers they have been denying something. Summer uses this phrase to conclude his argument of pollution dumping.   Ã‚  Ã‚  Ã‚  Ã‚   (A2) In the second argument, Summer’s discusses his opinion of Environmental issues. He states, â€Å"I’ve always thought that under-populated countries in Africa are vastly under-polluted.† This is clearly a subjective claim and Summer’s opinion. He vaguely assumes that a country could be â€Å"under-polluted†. The pollution of the world is not a natural occurrence; the waste of man creates it. This waste should not be pressured upon a geographical area if they do not create it. A clean and healthy environment is the only thing many lesser-developed countries have to cherish.

A Precious Gift :: Personal Narrative Essays

A Precious Gift Education has always been considered very important in my family. Prior to the earliest time I can remember I am told that my mother and father read to me nightly. My family has a deep background in books, my father being a collector, and my mother working at a library. My father loves books, in every way I can think of. He loves to read them, as do the rest of my family, but he has a collector's interest in books that we lack. He once wondered to a local library to check if they had a book sale. They did indeed have a book sale, and he bought quite a many books from their shelves. Soon he became a volunteer, and then the organizer, and soon had his own key to the library. As the relationship between my father and I goes, I started going with him to the book sale. I loved reading and I helped him a little also. We discovered that the special semiannual book sale was coming up. I came with my dad that morning and we began carrying boxes of books out to the tables. We observed a tag sale across from us that apparently went hand in hand with our sale. I was given the job of collecting money, and the day was going well, for we had already made nearly four hundred dollars for the library. At one point a small boy began his ascent up the small hill from the tag sale. He was only seven or eight by my estimate, and went directly to the table marked 'children.' After a minute or two he had found four or five books that he liked, put them in a neat pile and started his way back down the hill to the tag sale. Nearly a minute later he came back with a rather sad look on his face. "What's the matter?" I asked him as he took the pile and placed the books back on the table. He shrugged and I pushed. "You don't want those books?" I asked. I could tell he was shy. We already had something in common. "No, I can't get them." "Oh? Why not?" I asked. I could sense that he wanted them. "Because my mother won't give me the money for the 'stupid books.

High School Life Essay

It was in the year 2009, I was a graduating elementary student back then, when our adviser talked to me, together with my fellow honor students, regarding our plans after graduation. The conversation included where we wanted to study in high school. Most of us said that a simple school will do, what’s important for us back then was to have a school. That simple. After a few words, our adviser said that there is prestigious school inviting us to study there. Our initial reaction was, of course, we have no money to pay for the tuition fee. But then, she said that we need not worry, because the school offers us 100% scholarship, with a weekly allowance. We were delighted by the news. Imagine being a scholar of Notre Dame of Greater Manila. That is something to be proud of. So we were scheduled for an exam. We were so nervous. After several days of waiting, the results came out. And I was the one chosen to be the scholar! When my mom told me the news, I was really overjoyed. It would be my first time to study in a private school, prestigious one even. I went to the school to arrange my requirements there. That was when I knew that I am a De Mazenod Lingap Talino (DMLT) scholar, who would enjoy 100% scholarship and weekly allowance. What a privilege! I also met there Mr. Diego Reyes, or Sir Jigs, as what the whole institution calls him, and Ma’am Sofie. They were the ones who helped me during my stay there as a scholar. My first year was tough. A lot of adjustments were done. Of course, I’m not used to having classmates who are techy and rich. They talked about this gadget and that gadget, which, in my previous school, is not an issue. I’m not used to seeing signature clothes and bags. So I didn’t know how I would approach them. I’m not rich as them. I am just a simple girl. Another reason why I’m afraid is because I thought I would not be accepted there. I am different, physically. Before the first day of school, I imagined the Damers teasing me and bullying me. And I imagined myself ignoring them, as if they don’t exist, and when I’m alone, I’d cry a lot just to let the feelings out. I thought I would be an outcast, a loner, weirdo in their eyes. But I was completely wrong. I gained a lot of friends, much many than I thought I’d have. My first impression of them was wrong. They are not like what I see in the movies, rich people who are arrogant and rude. They understand my situation. They are open-minded. They are real. They may tease me but that was only natural, I do not get offended. They are real, true friends. Of course, the teachers are a plus. I thought they would not like me, especially the Math teachers, because I’m really weak in that particular subject. I really like Math, but I guess the feeling ain’t mutual. Until now, I still use finger Math. I am extremely slow in solving problems. I thought Math teachers would lose their patience on me, ignore my presence in the cream class because they would think I don’t belong there, because I am a weakling. But then again, I was W-R-O-N-G. Math teachers in Notre are exactly the opposite of what I thought they would be. They are very kind, especially Mrs. Narciso, Ms.Padlan, Mr.R and Mr. Zuniga. They were the ones whom I spend my Math classes with during my entire stay in high school. They were the ones who taught me Math and helped me to improve my skills in that field. They showed me that I am not a weakling, I still have hope. Whoo. But of course, there were my second parents. Mrs. Mercado and Mrs. Asis who served as my mothers, and Mr. Saplagio as my dad. They were the ones whom I turn to and cry on whenever I have problems. And all of the teachers in Notre, who may seem terror and scary inside the classrooms, but outside, they are one of your bestest best friends. Being a scholar isn’t as easy as anyone thinks. It’s really tough maintaining your grades. It is stressing to think about your grades when they are going down. They say grades are just numbers, but I depend on those numbers. My scholarship depends on those numbers. I usually envy those who can just have fun while I am at my room studying even if there’s no exam. And of course, as a scholar, I should be a role model to others. I should take care of my reputation. But of course doing that is a bit hard. As the saying goes, â€Å"Character is what you are; reputation is what people think you are.† What if my character is different from my reputation? Yes, that happens all the time. But I just maintain my character and ignore those who pull me down by saying things about me behind my back. That made me stronger. Notre gave me a lot of experiences that I would not forget. Notre gave me people that I am thankful for. But of course, I would receive none of these if it wasn’t for the DMLT, for giving me this very wonderful opportunity to study in the institution. I am just a simple girl from a family who cannot afford the services of Notre. But because of Notre’s awareness of the students out there who are not financially able, yet deserving to have quality education, and it’s willingness to reach out to them, I was able to experience this once in a lifetime opportunity. Now, I am going to study in my dream school, the University in the Philippines, one of the most prestigious universities in the whole country. With the help of Notre, I was able to get this dream of mine. It equipped me with enough knowledge and skills to face the challenges ahead. My life in Notre had been stressful, yet everything was all worth it. For this, I would like to express my deep gratitude. Thank you, Notre Dame.

Philosophy of Education Essay

It was Chesterton, an English essayist, who once said that â€Å"the most practical thing about a man is his view of the universe – his philosophy† (Hocking 4).   Man’s philosophy is generally referred to as the sum of all his beliefs and views about the world which guide his actions.   His beliefs comprise all those judgments, whether they are based on convictions or impressions, which he habitually lives by. During the pre-service education and throughout the teaching career, teachers will have to face up to what it means to live and to teach in a society that gives the individual freedom to hold different beliefs and values.   In this society there seems to be no single â€Å"right† way of thinking about and doing things in education.   How teachers deal with school matters – objectives, contents, and methods – depend very much on their own individual beliefs and values.   They should be willing to take responsibility for giving their own answers to many problems they will meet in their classrooms regarding goals and values, and ways of teaching their students. 1. Organizing your classroom & materials. The teacher in the classroom is a veritable manager.   The success of the activities in the classroom depends on the ability of the teacher as classroom manager.   He is at the helm of all activities, and these activities will succeed depending on how well he can steer and guide them properly.   One of the most difficult problems that confront a beginning teacher is classroom management.   Unfortunately, he does not learn techniques of proper classroom management from books.   He merely gets suggestions on how to mange a class, but there is nothing like teaching experience that will really teach him all the tricks of classroom management. Hence, classroom management is one of the main concerns of teachers, administrators, and parents.  Ã‚   If the school is to live up to the community’s expectation that it is a learning-producing enterprise, the individual classrooms which comprise the school must contribute to the school’s educational productivity. Learning is the central goal of the total school operation, and teaching is the school’s basic production technique.   Effective teaching and effective learning take place in well-managed classrooms. When class time is consumed by management problems, students are the losers, for little real learning takes place.   As every teacher knows, good classroom management is one of the strongest influences on academic learning. 2. Choosing rules & procedures. A well managed classroom is hardly possible without laws, regulations, and conventions.   The classroom in itself is a society and needs its own rules and regulations to keep peace and harmony within it.   Certain classroom activities can be made automatic in the sense that they can be performed without much thought, especially when they have become habitual.   Such activities, we say, have become routinized.   It is apparent that routinizing classroom rules and procedures can help the teacher a lot in classroom management.   There are no hard-and-fast rules as to which activities can be reduced to routine.   Routinizing would depend on such factors as size of the class, the nature of students, materials available, arrangement of equipment, and the like. There are certain advantages in routinizing classroom rules and procedures and these are economy in time and effort, prevent confusion, and promote learning activity.   Much time is wasted on administrative activities that are not handled in a well-organized manner.   Activities that are repeatedly done may well be routinized so that pupils will know exactly what should be done. Some disadvantages should, however, be mentioned if routine factors are overmechanized.   If every little activity in the classroom is mechanized, no room for initiative is left to the pupils.   They may behave like automatons and certainly creativity is destroyed.   The teacher is reduced to an autocratic general and the pupils are regimented soldiers who merely wait for the chief’s signal or command.   Such a situation leads to blind obedience and acceptance of rules and procedures.   This type of atmosphere must be avoided by the teacher. Certain classroom rules and procedure, though, can be routinized so that more time can be devoted or allotted to more significant activities.   Among these activities are the roll calls, seating, handling materials and devices, classroom courtesies, and responses to the bell signals. The main goal here is to save time and effort.   Pupils should be made to understand and learn the value of time.   The old saying that time is gold should be clearly impressed on the minds of children. 3. Managing student work. One aspect of classroom management deals with managing student work.   The teacher takes full charge of the learning situation should manipulate the learner and the situation to produce the desired learning.   Managing implies arranging the learning situation so that the learner comes face to face with the stimulating problem.   While it is true that most teaching tends to foster teacher domination, manipulation, an intervention rather than the development of a genuine helping relationship, teachers can learn to dominate less and get students to participate more.   It is good practice for teachers not to repeat their questions, answer their own questions, or repeat answers of students. Some teachers tend to be autocratic or authoritarian.   Experience and research findings show that democratic teachers produce better learning results than those who dominate, control, or manipulate learning situations.   Teachers should determine the psychological needs of their students and adapt their teaching styles accordingly.   The teacher who encourages a two-way communication in the classroom insures a favorable teaching-learning climate.   To understand better the complexities of learning and classroom behavior, classrooms must be pupil centered rather than teacher centered. 4. Getting off to a good start. Getting off a good start requires careful attention to how teacher’s teach rules and procedures to their classes.   The tone of the class is set by the personal disposition that a teacher displays.   A teacher should bring a cheerful, pleasant and confident disposition to the classroom.   Once inside the room, a teacher’s face must be lit with joy to brighten the atmosphere.   Then, a teacher should take the necessary time during the first day of class to describe carefully your expectations for behavior and work.   Teachers should not be in a hurry to get started on content activities that teaching good behavior is neglected.   Rather, combine learning about procedures, rules, and course requirements with your initial content activities in order to build the foundation for the whole year program. 5. Planning & conducting instruction. Just as good classroom management enhances instruction by helping to create a good environment for learning, so too does effective instruction contribute to well-managed classroom.   With the change of emphasis on educational objectives, with the inclusion of more outcomes learning, with the focus on the child as the most important factor in the educational process, the concept of conducting instruction has likewise diversified and broadened.   In recent years, newer and more informal methods of instruction have come about.   Current practices have gradually replaced the undesirable features of so-called lesson hearing instruction.   This is due in part to the gradual acceptance of the newer philosophy of education, i.e. education is not merely a process of learning facts and storing knowledge, but it is concerned with the many sided development of the individual – social, emotional, and mental- including he ability to meet social needs. 6. Managing cooperative learning groups. Cooperative learning in mathematics is essential if math teachers are to promote the goals of problem-solving competency, ability to communicate mathematically, ability to reason mathematically, valuing of mathematics, and self-confidence in one’s ability to apply mathematics, and self-confidence in one’s ability to apply mathematical knowledge to new problem situations in one’s world.   Although competitive and individualistic assignments should at times be given (even though they place students in the role of being passive recipients of information), the dominant goal structure in math should be cooperative. There are a number of fairly simple ways teachers may begin to use cooperative learning in mathematics classes, including having students turn to their partners to decide on an answer to a question or having students work in pairs to check each other’s homework, involves far more than simply assigning students to groups and telling them  to work together. The teacher’s role in structuring learning situations cooperatively involves clearly specifying the objectives for the lesson, placing students in learning groups and providing appropriate materials, clearly explaining the cooperative goal structure and learning task, monitoring students as they work, and evaluating students` performance.   Teaching students the required interpersonal and small-group skills can be done simultaneously with teaching academic material.   In order to sustain the long-term implementation and in-classroom help and assistance needed to gain expertise in cooperative learning, teachers need support groups made up of colleagues who are also committed to mastering cooperative learning. 7. Maintaining appropriate student behavior. A number of educators have formulated some suggestions on ways to maintain good classroom student behavior.   The suggestions range from how to encourage students to behave and how to develop and maintain a positive approach to classroom management.   Some of these suggestions commonly used in the classrooms are: (1) Act as if you expect students to be orderly from the first day on; (2) Expect everyone’s attention before starting to teach.   Stop when there is noise.   Don’t teach over individual or group chatter ;(3) don’t talk too much as after a while, you lose the students` attention.   Involve the students in activities, ask questions, pose problems, etc. ;(4)   Hold students accountable for abiding by rules. 8. Communication skills for teachers. Making a lesson presentation basically requires mastery and understanding of goals, skills and criteria for effective communication.   Communication skills is also at the very core of effective teaching.   As most teacher would agree that to communicate well is to teach well.   In the skillful use of the question more than anything else lies the fine art of teaching; for in it we have the guide to clear and vivid ideas, and the quick spur to imagination, the stimulus to thought, the incentive to action. 9. Managing problem behavior. It has been stressed time and again that good classroom discipline is indispensable to an effective learning situation.   All teachers, old or young, old or new in the service, are faced with problems of discipline. It is true that some teachers can maintain better discipline than can others. It is suggested that the best approach should be positive rather than negative.   The best measure should be preventive rather than remedial.   â€Å"An ounce of prevention is worth a pound of cure,† so the saying goes.   This adage is exactly what should guide the teacher.   Knowing the possible causes of disciplinary problems, the teacher should strive to eliminate them. 10. Managing special groups. One of the special challenges a teacher should face is managing special groups successfully.   Of course, these groups have an impact on the management of student behavior as well as on instruction.   Experience have proven that attempting to cope with these special groups by using many different assignments, providing an individualized, self-paced program, or using small group instruction extensively in secondary school increases the complexity of classroom management, requires a great deal of planning and preparation, and require instructional materials that are not readily available.   So, rather than altering the instructional approach, experienced teachers provide for different levels of student ability by supplementing their whole-class instruction with limited use of special materials, activities , assignments, and small group work. So, to the question of which administrative procedure is most effective in managing special groups, only one answer can be given.   All ca n be effective if used with discretion and with the right children. Conclusion The teacher’s total philosophy of life cannot be separated from his philosophy of education, his learning theory, and his methods of teaching.   In other words, how he thinks about his work and the way he performs his functions as a teacher are derived from what he believes about the nature of the world, knowledge, and values. In philosophical terms, his world-view lies in the realm of the metaphysical, his knowledge-view in the epistemological, and his values in the axiological.   These are the philosophies which teachers consciously or unconsciously deal with in the teaching world. Every committed teacher tries to work out his own philosophy of education, clarifies his beliefs and ideals to make his teaching meaningful to himself and to his students.   Without a philosophy of education, the teacher will be easily swayed by fads in education.   Because his life and work involve making choices and decisions, the teacher cannot avoid having a philosophy.   Even when courses of study are dictated, he always has the freedom to decide how he will teach and to select the contents and methods of teaching.

Newtons Law Of Motion Computer Science Essay

In this assignment, I will larn about the result two that is Newton ‘s jurisprudence and harmonic oscillation. Newton ‘s jurisprudence can be divide by three types that is 1st jurisprudence, 2nd jurisprudence and 3rd jurisprudence. It is teach about the gesture in our existent life. Thus, harmonic oscillation can be divided by three types that are pendulum oscillation, damped oscillation and mechanic oscillation. All of these oscillation are utile in our life especial is use in different type of mechanics.Question OneResearch on the Newton ‘s Laws of gesture, and do a study that provide item account and illustrations on Newton ‘s 3 Torahs of gesture. You report should include relevant and utile expression.AnswerNewton ‘s jurisprudence of gesture can be divided by three types that is 1st jurisprudence, 2nd jurisprudence and 3rd jurisprudence and it is jurisprudence of gravitation. The three Torahs are simple and reasonable. The first jurisprudence provinces that a force must be applied to an object in order to alter its speed. When the object ‘s speed is altering that average it is speed uping, which implies a relationship between force and acceleration. The 2nd jurisprudence, the acceration of an object is straight relative to the net force moving on it and is reciprocally relative to its mass. The way of the acceleration is in the way of the acceleration is in the way of the net force moving on the object. Finally, the 3rd Torahs, whenever we push on something, it pushes back with equal force in the opposite way.ForcesA force is normally imagined as a push or a pull on some object, possibly quickly, as when we hit a tennis ball with a racket. ( see figure 1.0 ) . We can hit the ball at different velocities and direct it ionto different parts of the oppositions ; s tribunal. This mean that we can command the magnitude of the applied force and alos its way, so force is a vector measure, merely like speed and acceleration. Figure 1.0: Tennis title-holder Rafael Nadal strikes the ball with his racket, using a force and directing the ball into the unfastened portion of the tribunal. Figure 1.1: Examples of forces applied to assorted objects. In each instance, a force acts on the object surrounded by the dotted lines. Something in the environment external to the boxed country exerts the force.Newton ‘s 1st jurisprudenceNewton ‘s 1st jurisprudence of gesture provinces that if a organic structure is at remainder it will stay at the remainder and if a organic structure is traveling in a consecutive line with unvarying speed will maintain traveling unless an external force is acted upon. For illustration, see a book lying on a tabular array. Obviously, the book remains at remainder if left entirely. Now imagine forcing the book with a horizontal force great plenty to get the better of the force of clash between the book and the tabular array, puting the book in gesture. Because the magnitude of the applied force exceeds the magnitude of the clash force, the book to a halt. Now imagine the book across a smooth floor. The book once more comes to rest one time the force is no longer applied, but non every bit rapidly as earlier. Finally, if the book is traveling on a horizontal frictionless surface, it continues to travel in a consecutive line with changeless speed until it hits a wall or some other obstructor. However, an object moving on a frictionless surface, it ‘s non the nature of an object to halt, one time set in gesture, but instead to continues in its original province of gesture. This attack was subsequently formalized as Newton ‘s first jurisprudence of gesture: An object moves with a speed that is changeless in magnitude and way, unless acted on by a nonzero net force. For illustration: In the figure 1.2, the twine is supplying centripetal force to travel the ball in a circle around 3600. If sudden the twine was break, the ball will travel off in a consecutive line and the gesture in the absence of the restraining force. This illustration is non hold other net forces are moving, such as horizontal gesture on a frictionless surface. Figure 1.2InactivenessInertia is the reluctance of an object to alter its province of gesture. This means if an object is at remainder it will stay at remainder or if it ‘s traveling it will maintain traveling in a consecutive line with unvarying speed. Force is needed to get the better of inactiveness.For illustrationIn figure 1.3, it is an experiment to turn out the construct of inactiveness. In experiments utilizing a brace of inclined planes confronting each other, Galileo observed that a ball would up the opposite plane to the same tallness and turn over down one plane. If smooth surface are used, the ball is roll up to the opposite plane and return to the original tallness. When it is get downing to turn over down the ball on the degree topographic point, it is will return the ball at the same tallness from original point. Figure 1.3 If the opposite slope were elevated at about a 0 grade angle, so the ball will be roll in an attempt to make the original tallness that is show in the figure 1.4. Figure 1.4: If a ball stops when it attains its original tallness, so this ball would ne'er halt. It would turn over everlastingly if clash were absent.Other illustrationFigure 1.5: Harmonizing to Newton ‘s 1st jurisprudence, a bikes gesture was n't alteration until same force, such as braking makes it alteration.Newton 2nd jurisprudenceNewton ‘s first jurisprudence explains what happens to an object that has no net force moving on it. The object either remains at remainder or continues traveling in a consecutive line with changeless velocity. Newton ‘s 2nd jurisprudence is the acceleration of an object is straight relative to the net force moving on it and is reciprocally relative to its mass. The way of the acceleration is in the way of the acceleration is in the way of the acceleration is in the way of the net force moving on the object. Imagine forcing a block of ice across a frictionless horizontal surface. When you exert some horizontal force on the block, it moves with an acceleration of the 2m/s2. If you apply a force twice every bit big, the acceleration doubles to 4m/s2. Pushing three times as difficult triples the acceleration, and so on. From such observations, we conclude that the acceleration of an object is straight relative to the net force moving on it. Mass besides affects acceleration. Suppose you stack indistinguishable block of ice on top of each other while forcing the stack with changeless force. If the force applied to one block produces an acceleration of 2m/s2, so the acceleration drops to half that value, 1 m/s2, When 2 blocks are pushed, to one-third the initial value. When three block is pushed, and so on. We conclude that the acceleration of an object is reciprocally relative to its mass. These observations are summarized in Newton ‘s 2nd jurisprudence: The acceleration of an object is straight relative to the net force moving on it and reciprocally relative to its mass.Unit of measurements of Force and MassThe SI unit of force is the Newton. When 1 Newton of force Acts of the Apostless on an object that has a mass of 1 kilograms, it produces an acceleration of 1 m/s2 in the object. From this definition and Newton ‘s 2nd jurisprudence, we can see that the Newton can be expressed in footings of the cardinal units of mass, length and clip. 1 N = 1 kg.m/s2 A force is a push or a pull. Hence a force can alter the size, form, and province of remainder or gesture, way of gesture and velocity / speed. The symbol for force is F and the S.I. unit is Newton ( N ) . An object of mass m is subjected to a force F, its speed alterations from U to V in clip t. The above status can be stated as: F = Where a = is acceleration, therefore F = mom.For illustrationFigure 1.6: An airboat. An airboat with mass 3.50x102Kg, including riders, has an engine that produces a net horizontal force of 7.70x102N, after accounting for forces of opposition ( see figure 1.6 ) . ( a ) Find the acceleration of the airboat. ( B ) Get downing from remainder, how long does it take the airboat to make a velocity of 12.0m/s2? ( degree Celsius ) After making this velocity, the pilot turns off the engine and impetuss to a Michigan over distance of 50.0m. Find the opposition force, presuming it ‘s changeless.Solution( a ) Find the acceleration of the airboat. Apply Newton ‘s 2nd jurisprudence and work out for the acceleration: Fnet = mom a = = = 2.20m/s2 ( B ) Find the clip necessary to make a velocity of 12.0m/s. Use the kinematics velocity equation: If t = 5.45s V = at + V0 = ( 2.20m/s2 ) ( 5.45 ) = 12.0m/s ( degree Celsius ) Find the opposition force after the engine is turned off. Using kinematics, find the net acceleration due to resistance forces V2 – = 2a I†x 0 – ( 12.0m/s ) 2 = 2a ( 50.0m ) = -12 / 100 = -0.12m/s2 Substitute the acceleration into Newton ‘s 2nd jurisprudence, happening the opposition force: Fresistance= mom = ( 3.50 X 102kg ) ( -144m/s2 ) = -504NImpulse and Impulsive ForceThe force, which acts during a short minute during a hit, is called Impulsive Force. Impulse is defined as the alteration of impulse, so Impulse = MV – Mu, since F = , therefore impulse can be written as: Impulsive force is Force = Impulse/Time. Unit is Newton ( N ) .The applications of unprompted forceIn existent life we tend to diminish the consequence of the unprompted force by cut downing the clip taken during hit.Gravitational force or gravitationGravity exists due to the Earth ‘s mass and it is Acts of the Apostless towards the centre of Earth. Object falling under the influence of gravitation will see free autumn. Assuming no other force acts upon it. Object sing free autumn will fall with acceleration ; gravitation has an approximative value of 10m/s2. The gravitative force moving on any object on Earth can be expressed as F=mg. This is besides every bit weight.For illustrationFind the gravitative force exerted by the Sun on a 79.0kg adult male located on Earth. The distance from the Sun to the Earth is about 1.50 Ten 1011 m, and the Sun ‘s mass is 1.99 Ten 1030kg.SolutionFsun = G = ( 6.67 X 10-11 Kg-1m3s2 ) = 0.413NNewton ‘s 3rd jurisprudenceThe action of one organic structure moving upon another organic structure tends to alter the gesture of the organic structure acted upon. This action is called a force. Because a force has both magnitude and way, it is a vector measure, and the old treatment on vector notation applies. Newton ‘s 3rd jurisprudence is the sum of force which you inflict upon on others will hold the same repelling force that act on you every bit good. Force is exerted on an object when it comes into contact with some other object. See the undertaking of driving a nail into a block of wood, for illustration, as illustrated in the figure 1.7 ( a ) . To speed up the nail and drive it into the block, the cock must exercise a net force on the nail. Newton is a individual stray force ( such as the force exerted by the cock on the nail ) could n't be. Alternatively, forces in nature ever exist in braces. Harmonizing to Newton, as the nail is driven into the block by the force exerted by the cock, the cock is slowed down and stopped by the force exerted by the nail. Newton described such mated forces with his 3rd jurisprudence: Whenever one object exerts a force on a 2nd object, the 2nd exerts an equal and opposite force on the first. This jurisprudence, which is illustrated in figure 1.7 ( B ) , province that a individual stray force ca n't be. The force F12 exerted by object 1 on object 2 is sometimes called the action force, and the force F12 exerted by object 2 on object 1 is called the reaction force. In world, either, either force can be labeled the action or reaction force. The action force is equal in magnitude to the reaction force and antonym in way. In all instances, the action and reaction forces act on different objects. For illustration, the force moving on a freely falling missile is the force exerted by Earth on the missile, Fg, and the magnitude of this force is its weight milligram. The reaction to coerce Fg is the force exerted by the missile on Earth, Fg = -Fg. The reaction force Fg must speed up the Earth towards the missile, merely as the action force Fg accelerates the missile towards the Earth. Because the Earth has such a big mass and its acceleration due to this reaction forces is negligibly little. Figure 1.7: Newton ‘s 3rd jurisprudence. ( a ) The force exerted by the cock on the nail is equal in magnitude and antonym in way to the force exerted by the nail on the cock. ( B ) The force F12 exerted by object 1 on object 2 is equal in magnitude and antonym in way to the force F21 exerted by object 2 on object 1. Newton ‘s 3rd jurisprudence invariably affects our activities in mundane life. Without it, no motive power of any sort would be possible, whether on pes, on a bike, or in a motorised vehicle. When walking, we exert a frictional force against the land. The reaction force of the land against our pes propels us frontward. In the same manner, the tired on a bike exert a frictional force against the land, and the reaction of the land pushes the bike frontward. This is called clash plays a big function in such reaction forces. Figure 1.8: In the figure 1.8, when a force pushes on an object, the object pushes back in the opposite way. The force of the forcing back is called the reaction force. This jurisprudence explains why we can travel a dinghy in H2O. The H2O pushes back on the oar every bit much as the oar pushes on the H2O, which moves the boat. The jurisprudence besides explains why the pull of gravitation does n't do a chair clang through the floor ; the floor pushes back plenty to countervail gravitation. When you hit a baseball, the chiropteran pushes on the ball, but the ball besides on the chiropteran. Figure 1.9Question TwoResearch and exemplify the assorted features of â€Å" Damped Oscillations † , your reply should besides include graphical show of these characteristic.AnswerIn the existent life, the vibrating gesture can be taken topographic point in ideal systems that are hovering indefinitely under the action of a additive restoring force. In many realistic system, resistive forces, such as clash, are present and retard the gesture of the system. Consequently, the mechanical energy of the system diminishes in clip, and the gesture is described as a damped oscillation. Therefore, in all existent mechanical systems, forces of clash retard the gesture, so the systems do n't hover indefinitely. The clash reduces the mechanical energy of the system as clip base on ballss, and the gesture is said to be damped. In the figure 2.0, daze absorbers in cars are one practical application of damped gesture. A daze absorber consists of a Piston traveling through a liquid such as oil. The upper portion of the daze absorber is steadfastly attached to the organic structure of the auto. When the auto travels over a bump in the route, holes in the Piston let it to travel up and down in the fluid in a damped manner. ( B ) Figure 2.0: ( a ) Angstrom daze absorber consists of a Piston hovering in a chamber filled with oil. As the Piston oscillates, the oil is squeezed through holes between the Piston and the chamber, doing a damping of the Piston ‘s oscillations. ( B ) One type of automotive suspension system, in which a daze absorber is placed inside a spiral spring at each wheel. Damped gesture varies with the fluid used. For illustration, if the fluid has a comparatively low viscousness, the vibrating gesture is preserved but the amplitude of quiver lessenings in clip and the gesture finally ceases. This procedure is known as under damped oscillation. The place vs. clip curve for an object undergoing such as oscillation appears in active figure 2.1. In the figure 2.2 compares three types of damped gesture, with curve ( a ) stand foring underdamped oscillation. If the fluid viscousness is increased, the object return quickly to equilibrium after it is released and does n't hover. In this instance the system is said to be critically damped, and is shown as curve ( B ) in the figure 2.2. The Piston return to the equilibrium place in the shortest clip possible without one time overshooting the equilibrium place. If the viscousness is greater still, the system is said to be overdamped. In this instance the Piston returns to equilibrium without of all time go thro ughing through the equilibrium point, but the clip required to make equilibrium is greater than in critical damping. As illustrated by curve ( degree Celsius ) in figure 2.2. Active figure 2.1: A graph of displacement versus clip for an under damped oscillator. Note the lessening in amplitude with clip. Figure 2.2: Plots of displacement versus clip for ( a ) an under damped oscillator, ( B ) a critically damped oscillator, and ( degree Celsius ) an overdamped oscillator. Damped oscillation is relative to the speed of the object and Acts of the Apostless in the way opposite that of the object ‘s speed relation to the medium. This type of force is frequently observed when an object is hovering easy in air, for case, because the resistive force can be expressed as R = -bv, where B is a changeless related to the strength of the resistive force, and the reconstructing force exerted on the system is -kx, Newton ‘s 2nd jurisprudence gives us = -kx – bv = soap -kx – B = m ~ ( I ) The solution of this differential equation requires mathematics that may non yet be familiar to you, so it will merely be started without cogent evidence. When the parametric quantities of the system are such that B & lt ; so that the resistive force is little, the solution to equation is Ten = ( Ae- ( b/2m ) T ) cos ( wt + ) ~ ( two ) Where the angular frequence of the gesture is = ~ ( three ) The object suspended from the spring experience both a force from the spring and a resistive force from the environing liquid. Active figure 2.1 shows the place as a map of clip for such a damped oscillator. We see that when the resistive force is comparatively little, the oscillating character of the gesture is preserved but the amplitude of quiver lessenings in clip and the gesture finally creases, this system is known as an underdamped oscillator. The dotted blue lines in active figure 2.1, which form the envelope of the oscillatory curve, represent the exponential factor that appears in equation ( two ) . The exponential factor shows that the amplitude decays exponentially with clip. It is convenient to show the angular frequence of quiver of a damped system ( three ) in the signifier=Where = a?sk/m represents the angular frequence of oscillation in the absence of a resistive force ( the undamped oscillator ) . In other words, when b=o, the resistive force is zero and the system oscillates with angular frequence, called the natural frequence. As the magnitude of the resistive force additions, the oscillations dampen more quickly. When B reaches a critical value bc, so that bc/2m = , the system does non hover and is said to be critically damped. In this instance, it returns to equilibrium in an exponential mode with clip, as in figure 2.2. Question Three: Simple Harmonic Motion ( SHM ) is a dynamical system typified by the gesture of a mass on a spring when it is capable to the additive elastic reconstructing force given by Hooke ‘s Law. The gesture is sinusoidal in clip and demonstrates a individual resonant frequence. What is the relationship between the tenseness and weight in the system? What is Hooke ‘s jurisprudence when applied to the system?AnswerOscillation of gesture is has one set of equations can be used to depict and foretell the motion of any object whose gesture is simple harmonic. The gesture of a vibrating object is simple harmonic if its acceleration is relative to its supplanting and its acceleration and supplanting are in opposite way. The 2nd slug point mean that are acceleration, and hence the end point force, ever acts towards the equilibrium place, where the supplanting is zero. Common illustrations of simple harmonic gesture include the oscillations of a simple pendulum and those of a mass suspended vertically on a spring. The diagram shows the size of the acceleration of a simple pendulum and a mass on a spring when they are given a little supplanting, x, from the equilibrium place. Figure 3.0 In the figure 3.0, the numerical value of the acceleration is equal to a changeless multiplied by the supplanting, demoing that acceleration is relative to displacement. Then, the negative value of the acceleration shows that it is in the opposite way to the supplanting, since acceleration and supplanting are both vector measures.Simple harmonic in a springIf you hang a mass from a spring, the mass will stretch the spring a certain sum and so come to rest. It is established when the pull of the spring upward on the mass is equal to the pull of the force of gravitation downward on the mass. The system, spring and mass, is said to be in equilibrium when that status is met. If the mass is up or down from the equilibrium place and release it, the spring will undergo simple harmonic gesture caused by a force moving to reconstruct the vibrating mass back to the equilibrium place. That force is called the restoring force and it is straight relative to magnitude of the supplanting and is directed opposite the supplanting. The necessary status for simple harmonic gesture is that a reconstructing force exists that meets the conditions stated symbolically as Fr = -kx, where K is the invariable of proportionality and ten is the supplanting from the equilibrium place. The subtraction mark, as usual, indicates that Fr has a way opposite that of ten.For illustrationFigure 3.1 The grouch rotates with angular speed w. Then, the slide will skid between P1 and P. V2 = W2 ( P2-X2 ) P = Amplitude or maximal point. V= Velocity of the skidder. Ten = Distance from centre point due to speed, V. W = Angular speed of grouch. = 2Iˆf degree Fahrenheit = = 1/T a = -w2xSimple pendulumA simple pendulum is merely a heavy atom suspended from one terminal of an nonextensile, weightless twine whose other terminal in fixed in a stiff support, this point being referred to as the point of suspension of the pendulum. Obviously, it is merely impossible to obtain such an idealised simple pendulum. In existent pattern, we take a little and heavy spherical British shilling tied to a long and all right silk yarn, the other terminal of which passes through a split cork firmly clamped in a suited base, the length ( a„â€Å" ) of the pendulum being measured from the point of suspension to the Centre of mass of the British shilling. In the figure 3.2, allow S be the point of suspension of the pendulum and 0, the mean or equilibrium place of the British shilling. On taking the British shilling a small to one side and so gently let go ofing it, the pendulum starts hovering about its average place, as indicated by the flecked lines. At any given blink of an eye, allow the supplanting of the pendulum from its average place SO into the place SA is I? . Then, the weight milligram of the British shilling, moving vertically downwards, exerts a torsion or minute – mg/sin I? about the point of suspension, be givening to convey it back to its average place, the negative mark of the torsion bespeaking that it is oppositely straight to the supplanting ( I? ) . Figure 3.2 If d2I?/dt2 be the acceleration of the British shilling, towards 0, and I its M.I about the point of suspension ( S ) , the minute of the force or the torsion moving on the bobn is besides equal to I.d2I?/dt2. I = -mga„â€Å"sinI? If I? is little, the amplitude of oscillation be little, we may pretermit all other footings except the first and take wickedness I? = I? . I = -mga„â€Å"I? , Whence, = Since M.I of the British shilling about the point of suspension ( S ) is ma„â€Å"2. We have = = = A µI? , Where = A µ The acceleration of the British shilling is therefore relative to its angular supplanting I? and is directed towards its average place 0. The pendulum therefore executes a simple harmonic gesture and its clip period is given by T = 2Iˆ = 2Iˆ = 2Iˆ It being clearly understood that the amplitude of the pendulum is little. The supplanting here being angular, alternatively of additive, it is evidently an illustration of an angular simple harmonic gesture.Hooke ‘s jurisprudenceVibration gesture is an object attached to a spring. We assume the object moves on a frictionless horizontal surface. If the spring is stretched or compressed a little distance ten from its equilibrium place and so released, it exerts a force on the object as shown in figure 3.3. From experiment the spring force is found to obey the equation F = -kx ~ ( four ) Where ten is the supplanting of the object from its equilibrium place ( x=0 ) and K is a positive invariable called the spring invariable. This force jurisprudence for springs is known as Hooke ‘s jurisprudence. The value of K is a step of the stiffness of the spring. Stiff springs have big K value, and soft springs have little K value. In the equation ( four ) , the negative mark mean that the force exerted by the spring is ever directed opposite the supplanting of the object. When the object is to the right of the equilibrium place, as in figure 3.3 ( a ) , x is positive and F is negative. This means that force is the negative way, to the left. When the object is to the left of equilibrium place, as in figure 3.3 ( degree Celsius ) , x is negative and F is positive, bespeaking that the way the force is to the right. Of class, when ten = 0, as in figure 3.3 ( B ) , the spring is unstretched and F =0. Because the spring force ever acts toward the equilibrium place, it is some clip called a restoring force. A reconstructing force ever pushes or pulls the object toward the equilibrium place. The procedure is so repeated, and the object continues to hover back and Forth over the same way. This type of gesture is called simple harmonic gesture. Simple harmonic gesture occurs when the net force along the way of gesture obeys Hooke ‘s jurisprudence – When the net force is relative to the supplanting from the equilibrium point and is ever directed toward the equilibrium point. Figure 3.3: The force exerted by a spring on an object varies with the supplanting of the object from the equilibrium place, x=0. ( a ) When ten is positive ( the spring is stretched ) . ( B ) When ten is zero ( the spring is unstretched ) , the spring force is zero, ( degree Celsius ) When ten is negative ( the spring is compressed ) , the spring force is to the right.DecisionAs my decision, Newton ‘s jurisprudence was a really utile in presents because it is can utilize the 3 type of jurisprudence to forestall any accidents in now coevals. First ‘s jurisprudence is provinces that a force must be applied to an object in order to alter its speed. Second ‘s jurisprudence is acceration of an object is straight relative to the net force moving on it and is reciprocally relative to its mass. Third ‘s jurisprudence is whenever we push on something, it pushes back with equal force in the opposite way. Second, harmonic oscillation is a type of forced and damped oscillation that is amplitude of a existent vacillation pendulum or hovering spring lessening easy with clip until the oscillation stop wholly. This decay of amplitude as a map of clip is called damping.
