Hands-on learning is used commonly in the science classroom to describe a form of learning where students investigate and develop understanding of a scientific concept by active involvement in an activity or an experiment (Gardiner, 2005). Askell-Williams and Lawson (as cited in Brophy, 2010) reported that middle school students frequently mention hands-on activities when asked about interesting elements of lessons, together with features which satisfy their need to for independence, competence and relatedness, experiments, outdoor learning, design projects, and innovative and creative assignments. Meanwhile, high school students enjoy classes for different reasons, and tend to rate highly those related to learning, creation,... Grounded on the findings of the study, all groups of respondents demonstrated their concurrence with the thesis statement that â€Å"hands-on learning motivates students in the science classroom†. The following conclusions were drawn for the specific objectives of the study. This report makes a conclusion that the uniqueness of each individual is one of the perplexities of humankind. Even twins have different set of fingerprints and different ways of learning styles and preferred teaching method. Even student teachers who are well-versed on the efficacy of various teaching methods prefer different teaching styles. The experienced science teachers recognized such individual differences and attributed different favorite teaching styles to such differences. The teachers declared that there is no one single style which can help develop the cognitive competence of students in science. In some concepts, however, one or a combination of two methods have proven to be more efficient that other styles. Teachers have to be aware of student preference and needs to adapt lessons and activities to these varying needs. The Science teachers enumerated several advantages and disadvantages of hands-on activities. Among the advantages identified were: hands-on activities e nable students to experience scientific phenomena through experiments with physical materials; these activities teach a student in planning investigations, utilization of scientific instruments, and in the collection, recording, and analysis of data.

What Features Should be Included in Online Examination System With the development of the Internet technology, online examination has become more and more poular since it helps people save much energy and time. As an efficient and effective way of teaching and learning, online examination can prevent from cheating and ensure the fairness of the examination results. A good examination system should be developed based on the needs of a real examination. Here are some features an examination system should provide: Examination Instructions The examination instructions will show the basis contents of the examination and something that should be paid attention to. Usually the following elements such as total questions, full score, passing rate, passing score, time limit, etc. are included in the instructions page. Accessibility of Examination Content Preset accounts and passwords can be set to protect the contents. And participants can register themselves online. Only authorized users can take the assessment contents. What’s more, domain hosting limitations can be set. Even if the participants have downloaded the flash assessment, it can not be played. Valid Time of Examination Content The participants can log in the examination system with their accounts and passwords to access the relevant page to complete the testing in the valid time. The examination will be unavailable when the valid time expires. Time Limit of the Examination Participants may log in the system to take the examination after the start time. When the testing time is used up, the examination results will be submitted by participants. Even if the examination is not completely finished at that moment, it will be submitted to the reporting system too. The start time and end time will be recorded precisely in seconds. Time Reminder for the Examination The time reminder will tell the participants how much time left during their examination. When it comes to the end of the testing, some alter audio will remind you of submiting your examination paper. Submission Ways Two ways to submit your answers to the reporting system: 1. Submit one question at a time. 2. Submit all at once. The former one means the participants can not review and modify their answers to their submitted questions. However, with the latter way of submiting, the participants can review and modify their answered questions before they submit the final answers. Result Release Immediate release or timed release can be set to the examination. For some examinations consisting of objective questions, the scores can be calculated automatically when the testing is over. The participants can view the results instantly. If you don’t want the results to be viewed so early or there are some subjective questions needs manual grading, you can finish the grading job first and then the participants can visit the system website to check their testing results. Chapter 1: Preliminary Investigation about Existing System 1. 1 INTRODUCTION Modern technology has added a new ingredient to this mix the Internet. The Internet can be regarded as a cheaper and improved version of the self-education resources. Some people like to take exam in a classroom is traditional manual examination because they are happy to sit there and have the teacher tell them what to learn, and when they get stuck, they are happy that there is someone there to help them, and they enjoy the social environment while taking exam. The traditional approach to measuring a persons level of knowledge in a topic has been the examination. These days there is often more emphasis on internal assessments, which may consist of assignments and projects given out and then marked or assessed. However examinations remain a popular component of many assessments. Source: Phillip Dorrell (2006) The author have noticed that most students wanting to acquire an admission into higher problems usually find it hard to achieve because those institutions make it a requirement to for the students to attain English certification which would verify that the students do speak and understand English. In order to help students acquire these scores, the author took it as a challenge to develop a test engine which would allow students to get the scores with ease. Examinations have the advantages of confidence that a large number of students are all being assessed equally and reduced opportunity for cheating. Users can use the system for writing the test and know about the system functionality. An individual can make use of the system by login in and taking a test. The main aim of carrying out a preliminary investigation is to attain much knowledge about understanding of problem, defining the project scope and constraints, identifying the benefits, estimating the time. Manual Exam Manual Exam is sort of an assessment that is intended to measure an individuals knowledge, skill and aptitude of a certain student or individual. This is also commonly known to test takers as â€Å"Written Tests† and is a manual exam developer’s choice of which style or format to use in creating and developing a written administered on a sheet of paper. A test taker who takes a written test could respond to such specific test items by writing it down manually within a given space of an examination paper or any separate sheet of documenttest is usually given that there is no such standard of testing. Be that as it may, certain exam style format have become widely used than others. Online Exam Online examination is an assesment that use network connection or internet in its process. Individuals and students must sign in on an assessment program or web link by entering their username and password. Then they choose the course that will be tested and the student start answering the questions that is shown on the screen. After they have finished the examination, the student taking the exam must click on a certain button that would require finishing the examination process. Even though this seems easy, online examination has its advantages and disadvantages as well. The students who agree that online examination is good has many advantages. Online examination can make the student’s life easier because they don’t need any paper and pen to do the examination. Furthermore, online examination can be effective and efficient. The students don’t waste much time to answer the questions because they only click on the best answer that is provided. One other advantage of online examination is that we can know our scores just after the exam. Sometimes, instructors can be very busy on a given day and do not have any time to check the exams. Online examination can solve this problem. The instructor does not need to check all of the exams. Online examination can do

New York 1939-1940 - Trylon and Perisphere :: Architecture History

New York 1939-1940 - Trylon and Perisphere As the 1939 New York World's Fair was divided into many different thematic zones, its planners wanted a central symbol for this event. The original idea was to have a theme center, with twin 250 feet towers and a semicircular hall to display dioramas. Wallace K. Harrison, a prominent New York architect of the Harrison Fouilhoux firm, was selected to design the theme center in November 1936. Harrison wanted a design that would represent a new architecture concept. In his own words, "we found ourselves constantly referring to the domes and campaniles of Venice, perhaps because the flat country and water of the Fair grounds are very like that of the site of Venice and in addition the sky color of New York is practically the same." (Newhouse,82) The idea of a large dome was a starting point for all further designs, and many different ideas were initially developed. There were plans to use a sphere that was suspended by steel cables, giving it a light, airy feel as well as a large balloon , anchored by steel cables and accessible by elevator. A spherical design was not a new idea, however. An earlier example of such a design was proposed by Etienne-Louis Boullà ©e in his project for Newton's Cenotaph in 1783, featuring a huge sphere at the center. In the end a design that featured a sphere 200 feet in diameter raised on pillars was selected. Despite its huge dimensions, with a 200-foot diameter, it was hard to grasp the exact scale of the sphere. Harrison and his design team finally came up with the idea of using a tall spike to frame the sphere, but there was still the problem of placing the two in relation with each other. They found inspiration from drawings by a Soviet constructivist architect named Jacob Tchernikhov, which represented two large spheres connected to a tall spike by way of a ramp. The final design had emerged. It included the Perisphere, a 200 foot spherical exhibit building, the Trylon, a 700 foot tall three sided obelisk, and the Helicline , a 950 foot circular ramp which connected the two and allowed visitors to exit. However the final dimensions of the building was reduced from the original values to a 180 foot sphere and a 610 foot spike due to budget limitations, which threw off the carefully calculated proportions. The Perisphere was elevated from the ground by five steel pillars, and rested over a large reflecting pool.

Summary Response of the Earth Is Full

In his article, The Earth Is Full, Friedman (2011) begins by stating that in recent years, first decade of 21st century, humanity encounters dangers that threaten humanity and the nature because of their unconcerned behaviors. Economic problems, high growing population rate and natural disasters compel humans to question about those recent years. The writer then moves on to the veteran Australian environmentalist-entrepreneur Paul Gilding and his book, Gilding, P. (2011) The Great Disruption: Why the climate crisis will bring on the end of shopping and the birth of a new world. More Summary of Devil at My HeelsNew York: Bloomsbury Press. Gilding (2011) discusses how much land and water area humanity needs to produce the resources they consume and absorb their waste. According to Gilding (2011), earth is growing at a dangerous rate and points out that over-used resources and worsening ecologic environment damage to social and economic system. Friedman reports the current growth rate is 150 percent of earth’s sustainable capacity and states that excessive use of resources and too much waste that creates the problem, â€Å"The Earth Is Full. He mentions about two loops; first, population growth and global warming push up food prices, which leads to political instability, which leads to higher oil prices, which leads to higher food prices, and so on in a insurmountable circle. Second, higher productivity means fewer jobs, which requires humans to produce more sources to create jobs. The more sources create global warming. Afterwards, the writer turns hi s attention to possible solutions. The solutions are discussed by giving Gilding’s eco-optimist view. In the article, also it is stated that economic systems are not changed without a crisis.Friedman (2011) states that â€Å"But don’t worry, we’re getting there. † Finally, Friedman prefers to use quotations from Gilding who say nations are heading for a crisis-driven choice and develop a new sustainable economic model slowly. Global warming, starvation, worsening ecological environment, exhaustion of resources, too much waste and the conflict between humanity and nature are very current and serious problems of the entire world. In the article these problems are discussed based on the fundamental source of the problems, high population rate. Also, based on Sullivan, M. 1999) Population control: How many are too many? , she states â€Å" Global warming, the thinning of the ozone layer, increasing crime rates, toxic chemicals in our food, and starvation in developing nations, each of which is at least partially due to growing world population† (Sullivan, 1999). According to that paper, there are now 5. 8 billion human beings on the planet now, and according to the United Nations, the population of earth is expected to grow to around 7. 9 billion by 2050. According to statistics, it is clear that growth rate is too much for the earth and causes a huge instability.In the article, Friedman, T. (2011) The Earth Is Full, some economic models are taken in hand as a basis for the solution. However, the damages that high population brings cannot be dispelled only with economic systems. Also, political systems must be developed and humans must be made conscious about all of those problems. †¢Friedman, T. (2011) The earth is full. NYT †¢Gilding, P.

Success and failure of Mergers, Acquisition and divestiture process

According to the Cambridge’s Internationals Dictionary of English, a Merger is when two or more companies join together, Acquisition is buying of a business by another company and finally divestiture is a process when a company takes back its investment from a less profitable company. Actually MA&D (Merger, Acquisition and divestiture) is a common process these days. The main motive behind is to increase profits and decline losses for the company.Say for instance if a company finds buying another company to be very beneficial in its upgradation process, increasing profitability or declining costs than that company can go for Acquisition or taking over of that company. Similarly due to high competition when some companies of same field, find it difficult to reduce the cost of production, logistics and marketing than few companies can come together in a contract or merge themselves in one big unit. Thus merger helps the companies to reduce their costs and increase the profitabil ity. Divestment is another common process these days.Actually those companies, which are not yielding enough of profits to the Parent Company or may be proving to be a big loss for the parent company, can be divested by the Parent Company. Thus by selling its shares from a weak or loss incurring unit a company can save its money. MA&D process. 2. MA&D process and its success: The present research shows that nearly 65 percent to 85 percent of corporate MA&D process fails. This process results in well short of expectations. The features of MA&D in the present day scenario are as follows. 1. The deals made are getting bigger thus increasing the scale of risk and reward. 2.To attain immediate gains from the big deals made by the companies, the opportunities gets missed that could capitalize on synergies that will deliver sustained, long term financial improvements and stake holders value. 3. The announcement of MA&D results many times in confusion both inside and outside the company, wh en the executives are a unable to institutionalize a governance process that can maintain momentum through integration. 4. Government institutions creates hurdle in the way of those MA&D process which could prove monopoly of a basic need products that could later on effect the price fixation monopoly by that company.Thus, today MA&D process is moving towards higher risks, lower productivity, confusion and government intervention. Success in the MA&D process: MA&D process. 3. The possible methods of getting successful in the MA&D process are suggested below. A. Post merger integration, business re-engineering and post divestiture separation present such an opportunity by which a person can estimate all the fields that could effect the business profitability in future. B. MA&D process needs to be planned and managed as well-structured hierarchical set of activities from beginning to the end. C.System Integration and outsourcing can help in leveraging MA&D activity to deliver results-d riven, sustainable operational transformation. D. Define and deploy a course of action appropriate for the type of MA&D like consolidation, combination, transformation or preservation. E. Plan and implement the transition to an optimized business model and infrastructure. F. Manage, operate and evolve the new applications and infrastructure. G. Identifying potential synergies in terms of people, process and IT and delivers these to plan. H. Ensure seamless separation of systems and data.MA&D process. 4. I. Rationalizes and streamlines infrastructure and processes. Thus from the above the following critical factors for success can be evaluated. 1. Clear intent 2. Perseverance 3. Leadership 4. Accountability 5. Leverage 6. Coordination 7. Experience 8. Focus 9. Decisiveness 10. Communication Present day scenario: The present figures state that nearly 65 percent of the failed in the MA&D process. Reason was overlooking of some features. The success and failure of the MA&D depends on th e following facts that need to be dealt carefully. MA&D process. 5.That is if the following facts are taken into consideration than only the MA&D process can prove to be beneficial for the company. Otherwise MA&D process can prove to be big mistake. 1. IT integration efforts make MA&D difficult: ERP or Enterprise resource planning applications like SAP has become ubiquitous in large organizations today. The promise is business process simplification, enhanced productivity and seamless information transfer. However these applications also require that businesses be wired together, typically through a single, unified database and other infrastructure.This of course, means individual businesses are far more difficult to separate. For instance , when Pfizer divested its Adam and Schick units, significant effort went toward figuring out how to separate data of the entities while blocking access to each other’s information. 2. Support services and facilities are hard to unravel: Ac hieving scale through shared support services and joint facilities is a broad trend in the business community. The more successful a company has been at this the greater difficulty it will face unwinding these collaborations. One big part of this is staff allocation.The trend toward shared support services has extended through general and administrative functions, call centers, account payable and receivable, payroll administration, and compensation and benefits plan management. MA&D process. 6. Carving out pieces of these integrated functions carries real challenges. 3. Outsourcing adds third party issues to MA&D: Not only are organizations centralizing they are outsourcing as well. In some way this may ease the process of separation, as the organization no longer owns the employees, systems and processes. Outsourcing firms are also very good at splitting workflow.If only it were that simple. In addition numerous perhaps hundreds of vendor relationships, outsourcing generally invol ves processes that are critical to a company’s core businesses. Therefore divesting a unit with significant outsourcing substantially increases the need for a rigorous review of services agreements to understand change of control provisions and to assess how service will continue going forward. 4. The divested business may require long term support: Until the divested business is prepared to stand on its own or is fully supported by the buyer it likely will need support from its former parent.Establishing clear service level agreements or SLAs between the buyer and the seller is critical. For highly integrated global businesses this can leas to country by country agreements, each involving dozens of services such as facilities management, back offices support and sales and manufacturing. MA&D process. 7. Conflicting interest can complicate the SLA process. For example depending on the situation the selling organization may have incentive to either prolong or limit the time fr ame on which these services will be provided. 5.Disruption threatens both seller and divested entity: Like a merger in reverse, a MA&D done right requires a plan detailed across every function, carefully monitored and adjusted as execution unfolds. This is a major project. Developing the separation plan often requires three-way collaboration between the seller and its remaining businesses, the divested unit itself, in some cases the buyer. The complexity of managing this separation planning across every function of the business and across the globe can rapidly absorb all attention of the businesses.The real danger here is underestimating just how much effort this will require. 6. The MA&D can impact the seller’s cost structure: Once the seller has carved out the divested business, it may well need to take another look at its own cost structure. In some cases, there can be loss of scale in areas where work was combined with the divested business. In the earlier, Pfizer example , customer service employees who had supported the divested Adams businesses were rationalized because the buyer, Cadbury Schweppes, did not require their services.MA&D process. 8. However this did not fully make up for the loss of scale. It took additional work with the customer service model, automating orders and other improvements to get the cost structure back in line. 7. Regulatory requirements can force your hand: Regulatory requirements on both local and global levels often create additional complexities. For example, MA&D may be required to resolve anti-trust concerns for a merger transaction. In these situations an organization may have to give up capabilities it would otherwise no elect to relinquish.As part of the Linde-Boc merger, regulators required that Northern American business be divested and operate as a stand-alone business, forcing Linde-BOC to part with both capabilities and people it would otherwise want to retain. Similarly in MA&D with European components, n egotiation with world’s councils on a country by country basis can lengthen the MA&D process and create additional constraints. Conclusion: Mergers, acquisitions and divestiture (MA&D) can make or break your business. And more and more organizations are looking to these initiatives to deliver quick and dramatic financial returns. 006 clocked up a staggering $4 trillion worth of deals, representing an average 30% growth, while the average deal size is also rocketing. MA&D process.9. As the merger wave rolls on, it is clear that many companies are taking this opportunity to divest non-core businesses. After all were in an active markets and there’re plenty of buyers- financial and strategic –sitting on hordes of cash and looking for attractive deals. However before moving to cash in on businesses you think will be attractive it is worth taking a hard look at the process of MA&D. Whether its an out fright sale or even a spin off to shareholders.Does all these means MA&D is a bad idea? Of course not . I many cases they are absolutely the right things to do. The trick is to be aware of the seven challenges in advance, and all seven are equally valid for MA&D of every size and use that knowledge when assessing any proposed transaction. There are many assessments to be made. 1. How much of the business to sell? 2. Could a strategic buyer more appropriate than a financial buyer? 3. Which is better an MA&D or a spin off? Truly understanding answers to these questions can help a seller get the very best deal in the broadest sense of the term.

Cuban Missile Crissis essays

Cuban Missile Crissis essays Back in 1962 most people thought there could not be a nuclear war. It was a time occupied by the Cold War. They were wrong. The U.S.A, Soviet Union, and Cuban countries were so close they could feel nuclear war breathing down their necks. The people of the U.S. were so close to being incinerated, and they didn't even know it. The Soviets had such a build up of missiles in Cuba they could have wiped-out most of the continental United States. The build up of these missiles, and the problems faced in October of 1962 are known as the Cuban missile Crisis. On October twenty second, 1962, John F. Kennedy, who that evening revealed the presence of Soviet missiles on Cuba, the crisis was nearly a weak old. In President Kennedy ¹s television broadcast, he informed the population that U.S. surveillance of the Soviet military build-up on the island of Cuba had uncovered a series of offensive missile sites now in preparation to fire. This declared that the purpose of these bases could be none other than to provide a nuclear strike capability against the Western Hemisphere. Kennedy called for a prompt dismantling and withdrawal of all offensive weapons under the United Nations supervision. In one minor aspect, Kennedy was mistaken. The soviet decision only seemed sudden. Actually taken five months earlier, it was both a high-stakes gamble and the logical product of sustained provocation. More importantly, the President misread the Kremlin ¹s motives. Gaining a nuclear strike capability was not Khrushev ¹s only or main purpose. In Fact , the soviet leader had persuaded his politburo colleagues that U.S. aggression against Cuba was all too likely and could only be overcome by the installation of the medium-range R-12 ballistic missiles and intermediate-range R-14 ballistic missiles and that specially trained people had to go Cuba to make them operational. Between October fourteenth and October twenty-eighth 1962 the world was never closer to ...

Free Essays on Abraham Maslow

Abraham Maslow Abraham Harold Maslow was born April 1, 1907 in Brooklyn, New York. He was the eldest of seven children born to his immigrant parents. While growing up, Abraham’s parents pushed their children hard toward academic success. He was very lonely as a boy, and sought refuge in his schoolwork. To please his parents, He went to study at the City College of New York. His father hoped he would study law, but he went to graduate school at the University of Wisconsin to study psychology. While in attendance there, he met and married his cousin Bertha Goodman, and met his cheif mentor Harry Harlow. At Wisconsin, he began a study of primate dominance behavior and sexuality. He went on to further research at Columbia University, continuing similar studies. There he found a new mentor Alfred Adler, who was one of Sigmund Freud’s early followers. From 1937 to 1951, Maslow was an instructor at Brooklyn College. Here he met Ruth Benedict and Max Wertheimer, whom he admired gre atly. These two were so accomplished, and such wonderful human beings in his opinion, that he began taking notes on them and their behavior. This was the beginning of his lifelong research on mental health and human potential. He wrote a great deal about the subject, borrowing from other theorist but adding significantly to them, especially the concepts of a hierarchy of needs, met needs, self-actualizing person’s, and peak experiences. Maslow became the leader of humanistic school o0f psychology that emerged in the 1950’s and 1960’s. He spent his final years in semi-retirement California, until June 8, 1970, he died of a hear attack after years of bad health. During and after his death, Maslow has been very inspirational figure in personality theories. In 1960’s, people were tired of the reductionistic, mechanistic messages of the behaviorists and physiological psychologists. They were looking for meaning and purpose in their lives...

How to Define Value in Relation to Art

How to Define Value in Relation to Art As an element of art, value refers to the visible lightness or darkness of a color. Value is synonymous with luminosity in this context and can be measured in various units designating electromagnetic radiation. Indeed, the science of optics  is a fascinating branch of physics, albeit one to which visual artists typically devote little to no thought. Value is relevant to the lightness or darkness of any color, but its importance is easy to visualize in a work with no colors other than black, white, and a grayscale. For a great example of value in action, think of a black and white photograph. You can easily visualize how the infinite variations of gray suggest planes and textures. The Subjective Value of Art While value can be a technical term related to color, it can be a more subjective term related to either the importance of a work or its monetary worth. Value can also refer to the sentimental, cultural, ritualistic, or aesthetic importance of work. Unlike luminosity, this type of value cannot be measured. It is entirely subjective and open to, literally, billions of interpretations.   For instance, anyone can admire a sand mandala, but its creation and destruction hold specific ceremonial values in Tibetan Buddhism. Leonardos ​Last Supper ​mural was a technical disaster, but its depiction of a defining moment in Christianity has made it a religious treasure worthy of conservation. Egypt, Greece, Peru, and other countries have sought the return of significant cultural works of art that were sold abroad in earlier centuries. Many a mother has carefully preserved many pieces of refrigerator art, for their emotional value is incalculable.   The Monetary Value of Art Value may additionally refer to the monetary worth attached to any given work of art. In this context, value is pertinent to resale prices  or  insurance premiums. Fiscal value is primarily objective, assigned by acknowledged art-historic specialists who eat, breathe and sleep fine art market values.  To a smaller extent, this definition of value is subjective in that certain collectors are willing to pay any amount of money to own a particular work of art. To illustrate this seeming dichotomy, refer to the  May 16, 2007, Post-War and Contemporary Art Evening Sale at Christies New York City showroom. One of original Marilyn silkscreen paintings by Andy Warhol had an estimated (objective) pre-sale value of more than  $18,000,000. $18,000,001 would have been accurate, but the actual gavel price plus buyers premium was a whopping (subjective)  $28,040,000. Someone, somewhere obviously felt that hanging in his or her underground lair was worth an additional $10,000,000. Quotations About Value In preparing a study or a picture, it seems to me very important to begin by an indication of the darkest values... and to continue in order to the lightest value. From the darkest to the lightest I would establish twenty shades.(Jean-Baptiste-Camille Corot) Strive not to be a success, but rather to be of value.(Albert Einstein) Its impossible to make a picture without values. Values are the basis. If they are not, tell me what is the basis.(William Morris Hunt) Nowadays people know the price of everything and the value of nothing.(Oscar Wilde) Color is an inborn gift, but appreciation of value is merely training of the eye, which everyone ought to be able to acquire.(John Singer Sargent) There is no value in life except what you choose to place upon it and no happiness in any place except what you bring to it yourself.(Henry David Thoreau)

Muhammad Ali Clay ( Cassius Marcellus ) 1942 - 1981 Essay

Muhammad Ali Clay ( Cassius Marcellus ) 1942 - 1981 - Essay Example For instance, he started training when he was only 12 years old. However, irrespective of the tender age of training, the super man acquired several skills, expertise as well as experience. This pushed him towards the realization of his first global success at the age of 221. For instance, it was at the age of 22 when Muhammad Ali first won the World heavyweight championship. This happened in the year 1964. The victory really motivated Muhammad Ali. As such, he vowed to put even more effort in order to succeed at each and every boxing event. It is of crucial significance to underscore the fact that Muhammad Ali was born a Christian. However, as he continued to grow, he later on converted to Islam. This happened in the year 1975 when he was 33 years old. Born in Louisville, Kentucky in the United States of America, Muhammad Ali, also known as Cassius Marcellus Clay played a total of 61 fights. Amongst these fight matches, he won 56 and lost 5. Amongst his victories, his total wins by knock outs included 37 in number. This paper is going to focus on Muhammad Ali relevant to his religious perspectives as well as the issue of women. Moreover, the paper is going to focus on the views of Muhammad Ali relevant to wars as well as maintenance of peace amongst individuals in the society. Furthermore, the paper is going to focus on Muhammad Ali’s take on the issue of racism as well as equality of all the people regardless of differences in races, religion as well as ethnic backgrounds. It is of crucial significance to note that Muhammad Ali, also known as Cassius Clay was really opposed to the issue of racism in the United States of America. Muhammad Ali is someone who deeply the valued the issue of equality amongst all humanities. However, it is of crucial significance to underscore the fact that the issue of racism greatly undermined as well as compromised the issue

THE LAW OF TORT Essay Example | Topics and Well Written Essays - 500 words

THE LAW OF TORT - Essay Example Simon had a dizzy neck after his car accident and had gone to see the doctor who diagnosed him of whiplash. After hearing that he has a vital presentation to present before the final of the programme, he advised Simon to return to the gym and work out through the pain. This was a wrong advice on the part of the Company doctor. After listening to his advice, he worked through the pain, and as a consequence, Simon passed out during the presentation and was taken to hospital where he was diagnosed with trapped nerves in his neck and as a consequence, was unable to appear in the finale. Applying the rule of law laid down in the Boman Case, the Company doctor is liable for Simon passing out in the presentation and the subsequent diagnosis in the hospital. Simon would not have gone and worked out if he was not advised by his doctor to do so. Therefore, applying the tort of professional negligence, we come to the conclusion that the Company doctor is liable for the injuries which happened subsequent to training after getting diagnosed of whiplash. Looking at the remedy available to Simon, the doctor is liable to pay for the damages which occurred after he worked out at the gym, which includes the cost of treatment for getting diagnosed at the hospital, but not the losses incurred due the failure of Simon to attend the finale.These costs must be paid by the doctor to Simon as damages for the tort he committed,. He was negligent in his services and deserves to pay a price for such inefficient and nonprofessional advice. In the second issue, the case is whether Simon has a defence against the claim of the pedestrian for the damage to her laptop, her loss of book and her illness. The answer to this problem is yes Simon does have absolute defence against the claim of the pedestrian. The pedestrian was not remotely anywhere close to Simon’s responsibility of duty of care while the accident occurred. Simon does not owe her any duty of care in the first

Renewable Energy Literature Survey Dissertation

Renewable Energy Literature Survey - Dissertation Example It demonstrated how capital can be obtained for project financing through a combination of debt and equity investment, debt being available through bank loans, institutional debt or through public markets. The paper mentioned the possibility of procuring equity from internal or external sources in public and private markets, and sponsorship through developers, contractors, equipment suppliers, operators, off-takers and fuel suppliers, who are active equity investors. The factors limiting project finance of renewable energy power projects (REPP’s) were examined. The author indicated that resource and technology risks were high and that financial institutions lacked the experience in evaluating risks related to REPP’s. The author also noted that with the rapid change in technology and the shortage of REPP technology engineers, they would have lacked the technical expertise in this area to assess and monitor REPP’s. ... This therefore results in a smaller margin for project financing and consequently puts pressure on costs related to maintenance and overheads. The author also pointed out that government policies, which are often unpredictable, greatly affect the economies of REPP’s. The paper gave focus to the importance of equity, seeing it as the main protection against risks. Lenders will therefore favour equity contributions in the initial part of the project. Lenders see equity investment as a form of commitment by the developers and sponsors. The author also found that security was another significant consideration for the lender, so they would implement safeguards such as a fixed charge over the projects site; a floating charge over the assets of the projects company; requiring that all cash flow be paid into a project account where they would have control, and contingency funds in place for unforeseen problems. The experience and credit worthiness of all participants would also be con sidered by the lender. There financial strengths would be assessed and the ability of these parties to carry out their contractual obligations with the project company would be determined. The article highlighted a number of risks that should be considered. The risk areas include the project itself, technology, construction, fuel/resource, the market, regulatory risks, mitigation and pass through. Project risks affect the amount, timing and availability of funds for the project finance. For technology lenders want to ensure that it is tested and proven, and that it will not be obsolete anytime soon. In relation to the construction risks the paper looked at the probability of cost overruns and delays in completion; most importantly

Media Coursework Essay Example for Free

Media Coursework Essay For my GCSE media coursework I have been asked to write about a television soap or series. I have chosen to write about the popular soap, Eastenders. Eastenders is a fictional drama soap about a small community living in East London. First I shall explain what a soap is. A soap is a television program that is all about peoples daily lives and the events that happen. Soaps are ongoing, contemporary dramas. Contemporary means that the plots and storylines are all based on on real life events that can and do happen to real people. Ongoing means the plot of the soap is held out over the episodes. Soaps can be split into different categories such as, countryside soaps, city soaps, or police soaps. Emmerdale is an example of countryside soap, Coronation Street, Eastenders, as city soaps, and The Bill as a police soap. The reason television soaps are called soaps is because the soap used to be advertised on the side of soap packets. Soaps always end with a cliffhanger. When I say cliffhanger, I mean that at the end of the episode the main plot finishes half way through. This leaves the viewers wondering what will happen next, so they watch the next episode. On the other hand, series have a different way of keeping the viewers interested. At the end of the episode they show you a sneak preview of what will be happening in the next episode. I dont think this is a good way to make sure you keep your viewers because its spoils the surprise. A series has a new main plot for every episode, the plot is introduced as the episode begins and finishes as it ends. Series always have smaller plots. The idea for these is for you to keep in the back of your mind, so you keep watching. The smaller plots are carried on over two or three episodes, like in soap. Another way they keep people watching is by letting newspapers and magazines inform their readers of the future storylines. I dont think they should be allowed to do this because most people would rather watch the soap without knowing what will happen next. It makes the soap or series more enjoyable. By doing this, it means more people watch so they get more money. Another Eastender makes its money is by merchandising. In other words, Eastenders produce product which have a connection to Eastenders and try to sell them. On the Eastenders website (www. bbc. co. uk/eastenders) they sell items such as, mugs, T-shirt, books etc. All of which have some connection to Eastenders. They may have a picture of a character of Eastenders written across it. Series are not ongoing. They usually have about 12 episodes, then switch with a different series. Series also have different categories, such as, city and countryside series, relationship series, police, crime and prison series, comedy series, and hospital series. Both soaps and series exaggerate the plot to make it more interesting and attract more viewers. We know that it doesnt really happen like that in life but we except and believe it to make the soap work, if we didnt they would be no point in watching. Like in Eastenders, the characters live in a fictional city called Albert Square in East London. We all know this place doesnt exist but we believe in it. Julia Smith and Tony Holland created Eastenders as a rival for Coronation Street. The first ever episode was transmitted at 7pm on the 19th February 1985. For the first eight years, Eastenders was shown twice weekly but on the 11th April 1994, it was changed to three episodes per week. Now, in the year 2002, the standard yearly output with four episodes a week is 208 episodes plus the omnibus repeat on Sundays. However, there are often additional episodes filmed throughout the year, increasing the figure to between 210 and 215 episodes. I think one of the reasons it was changed to four times a week is because that is how many times Coronation Street is shown. Eastenders is one of the most successful BBC programs in history and to date is topping the charts with viewing figures of 11. 2milion viewers per weekday episode, which is equal to 53% share of television viewing. Eastenders is mostly watched by people aged 25- 45 with 34% of the viewers fitting in that age group. Closely following is the under24s which make up 24% of the viewers. The remaining 42% of the audience are the over 45s. Over half of the viewers are female whilst only 33% are male and 12% of Eastenders audience are children. The reason for such a low percentage of children, I think, is because Eastenders is on our screens at round about 7:30pm or 8:00pm and stays there for roughly half an hour. Most children would be in or going to bed. Eastenders is transmitted for our enjoyment, every Monday, Tuesday, Thursday, and Friday with a repeat every Sunday. I timed an episode of Eastenders. The viewing time was 27:06:92 minutes and the credits were 00:31:38 seconds, which together, give a total o 27:38:25 minutes. This is slightly over the target length for Eastenders, which is 27 minutes and 15 seconds. The maximum is 27:40:00 minutes. I also timed an episode of another popular soap, Coronation Street. I found out that Eastenders is on our screens for about 1 minute and 30 seconds longer than Coronation Street. The reason for this may be that, Coronation Street has a commercial break, which Eastenders doesnt have. A plot is the main storyline of the program. It usually involves two or more of the characters. Currently, the main plot of Eastenders includes Phil Mitchell, Peggy Mitchell, Sonja Jackson, Jamie Mitchell, Lisa Fowler and her and Phils baby, Louise. In a recent episode, Lisa took her baby and fled to Portugal. Phil wasnt happy about this; after all she had taken his child. Phil followed her to find his daughter. In the last episode, Phil pulled up in a taxi and climbed out with Louise. The viewers were then expecting Lisa to get out, but then the taxi pulled away. Phil had returned. Without Lisa. People were very suspicious and refused to believe when Phil lied to them saying that he and Lisa had came to an agreement. He said Lisa was suicidal and they had agreed it was best for Phil to take the baby. We found out that this was a complete lie when Peggy, was unpacking for Phil and she came across two passports. One was Phils and the other was Lisas. Peggy knows he is lying but she refuses to believe it and keeps quiet about it. This is the main plot at the moment, it only involves a few characters, but it is interesting to watch. Other issues that have been in the plot of Eastenders include, rape, abortion, teenage pregnancy, homosexuality, drug addiction, prostitution, divorce, extra marital affairs, unmarried mothers, mixed marriages, murder, gambling, adoption, teenage runaways, Alzheimers disease, HIV/AIDS, drink driving and euthanasia. I think that it is a good idea to broadcast these issues because all these subjects happen in real- life and it helps people to learn about it and how to cope if it should ever happen to them. These issues could also be involved in the sub- plot. Sub- plots are just like main plots but they involve fewer characters and are just there for us to keep in the back of our minds. If soaps only had one storyline, it might not involve your favourite character so you might not be interested in watching. The most recent sub- plots in Eastenders are involving Ian and his wife, Laura. Laura is pregnant, but we all know it isnt Ians child because he has had a vasectomy. Steven, Ians son has found out that Ian is not his real dad and that his real dad doesnt even live in England or know he has a son. Sonja made her boyfriend Jamie, sneak into Phils pub to find Lisas passport. Soaps usually have about three or four sub- plots. This means only about half of the cast is actually involved in one episode. They are roughly 35 different characters in the cast, two of whom have been in Eastenders since the first episode. The two characters that have been in Eastenders since the first episode are Adam Woodyatt, who plays Ian Beale and Wendy Richard, better known as Pauline Fowler. Adam Woodyatt is my favourite character. He is 34 years old and was born on the 28th June 1968. He was born in Walthamstow. Adam is one of the few cast members to actually come from the East End of London. Ian Beale is my favourite character because he is a very believable character. This is because if you combine Adams wonderful acting with the skill of the scriptwriters, it creates a real, believable character. Also, Ian is nearly always written into the script. So far, Ian has been through divorce more than twice, bankruptcy, his wife tried to murder him, he has slept with a prostitute, told his old fianci e, Mel, that his child was ill just so she would marry him and his most recent plot is that his current wife, Laura, is pregnant but the child is definitely not Ians. Ian Beale comes across as a sneaky, sly, wimp and he likes to get his own way. He always seems to be plotting something but his plans never work. He is a bit of a failure. As a businessman, as a husband and as a dad. His business failed when he went bankrupt, he has been married three or four times and his son has left him, to go see his real dad. Ian does not seem like a nice man. The reason I like him is because I feel quite sorry for him. Everything goes wrong and I think he deserves something nice to happen. Underneath, I think he is really sensitive. He cries a lot, I must have seen him cry about 5 times, usually to do with his children. Ian is a character I definitely wouldnt like to be, because he has a hard life. However, the character I would love to be is Janine Butcher. The actress Charlie Brooks has the task of being Janine Butcher. Charlies date of birth is 3rd May 1981 and is originally from Barmouth, North Wales. Her first appearance in the soap was on 22nd June 1989 when she was only eight years of age. She was the third actress to play Janine Butcher. Janine is a fairly pleasant character although she is awful to the people she dislikes. I think she is greatly misunderstood. She likes to get her own way, and if she doesnt she really can be a frightful person to be near. She is also uses people. She once made friends with a man called Terry, just to get her hands on his money and have a job and a place to stay. But, I would still like to be Janine because she knows how to have fun and is very witty. Janine also knows how to take care of herself. These are the reasons I admire her. On a whole, I think Eastenders is really realistic because they dont exaggerate the issues too much unlike other soaps. It is also fun and easy to watch. It doesnt matter if you miss one or two episodes because it is so easy to catch up on the plot. I really enjoy watching Eastenders along with 53% of television viewing and I think it is one of the best soaps to watch.

The Photovoltaic Energy Calculation Engineering Essay

The Photovoltaic Energy Calculation Engineering Essay We used the program PVSYST in order to calculate accurately the output of our photovoltaic installation. PVSYST was the only program we had access to and it is a very widely known industrial program for sizing and designing photovoltaic systems. We used the most up to date version of 5.0.6. Procedure First from the main menu above we choose project design and we select the stand alone system because ours is not connected with an existing grid (i.e. electrical generator) In order to create a project in PVSYST, here is the Eco-friendly bulk carrier, we have to define: The project name, which will identify the project in the file list in our data library. The geographical location. The hourly Meteo file, which is given from the program. A geographical site is defined by: its name, country, and world region, its geographical co-ordinates: latitude, longitude, altitude and time-zone, Monthly meteorological data. To be used in the simulation, the minimum meteorological data include: the monthly Global horizontal irradiation Monthly averages of the ambient temperature. Meteo values are displayed and easily defined on the screen. It is to be noted that for the verification of rather uncertain data, the clearness index Kt is also displayable, which is the irradiation actually received on earth, normalised to extra-terrestrial irradiation in monthly values. The monthly average of Kt should usually lie between about Kt = 0.25 and Kt = 0.75 at any place (PVSYST defaults). Monthly meteo values can be used as a basis for the generation of synthetic daily data. Then we generate a graph for the specific site (i.e. Broome): Where, the blue line is the clear day model (irradiation values with clear sky). The above graph shows us graphically the irradiation sum per month (diffuse and global) with daily change values. The Clearness Index Kt for Broome: We can see that the values range from 0.25 to 0.75 The ambient temperature changes through the year. The above graphs were generated by the program from the below table: Also it is interesting to show the solar path at Broome or what is the solar height with respect of the plane through the day in order to understand how the sun moves from east to west. The graph also shows some landmark dates (denoted as 1 to 7) where the sun changes height: Our next step to the program is to find the albedo Coefficient: The albedo coefficient is the fraction of global incident irradiation reflected by the ground in front of a tilted plane. This effect takes place during the reversal computation of the horizontal irradiation onto a tilted plane. The albedo seen by the plane is of course null for a horizontal plane, and increases with tilt. In the project definition, the albedo values can be adjusted each month in order to take any possible snow-cover into consideration. The value usually admitted in the urban localities is of the order of 0.14 to 0.22, and can go up till 0.8 for a snow-cover. Ideally, the best value is obtained by a direct measurement on the site. But in practice, except for vertical planes, this value does not take on any great importance as the albedo component is relatively weak in the incident global irradiation (this contribution can be visualised in the results of the simulation). The following table gives some usual values for the albedo: We used the 0.35 value of the Albedo coefficient because it matches on our material. After defining the above values through the program we proceeded to the orientation of our PV plane. Our project consist a fixed tilted plane (The plane tilt is defined as the angle between the plane and the horizontal), because we considered placing the panels at the hatches due to the fact that they would be exposed all day to the suns radiation. PVs are placed onto the hatches of the ship with zero tilt (Azimuth is zero as well because it doesnt affect the global on collector plane output. In northern hemisphere, the plane azimuth is defined as the angle between south and collector plane. In southern hemisphere, the plane azimuth is defined as the angle between north and collector plane). As the program calculated, our loss with respect to an optimum orientation is 3.8% and the available irradiation on this tilted plane is 2370kWh/m2 We also considered using various configurations of panels as to maximise the output per m2 before choosing the above configuration. The below configurations was rejected due to the sun is changing place constantly throughout the day and the ships movement reinforces the situation, we decided that the best configuration was the above due to sturdy design (one panel placed along the hatch), high efficiency (sun always hit the panel at any time) and simple installation. Using two panels on each hatch half, tilted for 25o each having an output of 2445 kWh/m2 and the loss to an optimum orientation is 0.7%. Sun hit the panels only east and west when the ship goes north. (Highest efficiency, complex design, not easy installation). Using two panels on each half, tilted for above 25o the output is greatly decreased and we have great loss to an optimum orientation. The next step is to calculate the near shadings effect or shading. Near shadings are partial shadings which affect only a part of the field. The shaded part changes during the day and over the seasons. We call shading factor the ratio of the illuminated part to the total area of the field, or inversely shading loss is its complement. Through the construction/perspective tool we created a model of the ship from the ships particulars with the PVs installed on it in order to calculate the shading loss we have in various positions of the ship: The real effect of partial shadings on the electrical production of the PV field is non-linear, and depends on the interconnections between the modules. In the PV array, the current of each cell string is limited by the current of the worst cell in the series. That is, when one only cell is shaded the entire string is strongly affected (which has also dramatic effects on the I/V(current/voltage) characteristics of the whole array). Even with by-pass protection diodes, this string does not participate more than slightly in the production of the PV array. This phenomenon is too complex to be treated in great detail . Nevertheless, the program provides a simplified method, giving the possibility of partitioning the field into rectangles, each of which supposed to represent a string of modules in series. Then it calculates a Shading factor according to strings, stating that as soon as a string is hit by a shadow, the entire string (rectangle) is considered as electrically unproductive. A lthough not perfect, this approach should give an upper limit for the real shading loss evaluation. In practice, one often observe that (except for regular arrangements like sheds), this upper limit is not so far from the lower limit (that is, the linear loss). And the losses percentage due to shading in any sun height. After we define the natural parameters, we proceeded to the system consumption during a month in the specific site (BROOME). We cannot apply the maximum load 669.64 kW because it is the 100% and it is impossible to achieve it, but we apply an acceptable amount of about 20% of the max output which is 140Kw as a fixed load for 12 hours. After that we proceed to battery set and module selection: Where: LOL Loss-of-load probability This value is the probability that the users needs cannot be supplied (i.e. the time fraction when the battery is disconnected due to the Low charge regulator security). It may be understood as the complement of the Solar fraction (although it is described in terms of time rather than energy). During the sizing process, the LOL requirement allows for determining the PV array size needed, for a given battery capacity. Here the default program value is 5% which is acceptable. Autonomy and battery sizing: In the Presizing process, the proposed battery pack capacity is determined according to the required autonomy of the system, given in days. The autonomy is defined as the time during which the load can be met with the battery alone, without any solar inputs, starting of course from a full charged battery state. With non-constant loads (seasonal or monthly definition, weekly use), this is accounted as the worst case over the year. The calculation takes the minimum state of charge (SOC) disconnecting threshold, and the battery energy efficiency into account. For our project we decided that 4 days is enough autonomy for our ship. Battery Voltage Choice In a stand-alone PV system with direct coupling to the user (without inverter), the battery voltage determines the distribution voltage. As now many DC appliances can be found as well in 24V as in 12V, this choice should be made according to system and/or appliance power, as well as the extension of the planned distribution grid to minimise the ohmic wiring losses. This choice should be done from the early planning of an installation, since the existing appliance voltage usually cannot be changed, and voltage translators will be expensive and not 100% efficient. The rated distribution values could be chosen according to the following criteria (inverter supposed directly connected on the battery pack): 12V: little systems for lighting and TV: Appliance max power 24V: medium size, with fridge and little appliances, or wiring extension to more than 10 m. Appliance max power 48V: special industrial or agricultural use Appliance max power Higher powers require either high DC voltages (special appliances) or AC feeding through inverter. Here we choose 440V The module which we choose was the highest output monocrystalline silicon module in the program database, from SunPower company, constructed in 2009 the specifications of the module are: The batteries specification ,model and Manufaturer: Continuing: below is a brief sketch of the system The battery operating temperature was set to a fixed value of 20oC and the program let us use a default regulator with a DC-DC converter which specs are above. Array Losses Array losses in PVSYST program: Array loss parameters are initially set to reasonable default values by the program, so that modifications only need to be performed during a second step of the system study. PVSYST treats in detail the following loss types in a PV array: Thermal losses Ohmic wiring losses Module quality losses Mismatch losses Incidence angle (IAM) losses. In the simulation results, the effect of each loss will be available in hourly, daily or monthly values. They may be visualized on the Loss diagram. Array Thermal losses Thermal Model The thermal behaviour of the field which strongly influences the electrical performances is determined by a thermal balance between ambient temperature and cells heating up due to incident irradiance: U  · (Tcell Tamb) = Alpha  · Ginc  · (1 Effic) Where Alpha is the absorption coefficient of solar irradiation, and Effic is the PV efficiency (related to the module area), i.e. the removed energy from the module. The usual value of the Absorption coefficient Alpha is 0.9. When possible, the PV efficiency is calculated according to the operating conditions of the module. Otherwise it is taken as 10%. The thermal behaviour is characterised by a thermal loss factor designed here by U (formerly called K-value), which can be splitted into a constant component Uc and a factor proportional to the wind velocity Uv: U = Uc + Uv  · v (U in [W/m ²Ã‚ ·k], v = wind velocity in [m/s]). These factors depend on the mounting mode of the modules. For free circulation, this coefficient refers to both faces, i.e. twice the area of the module. If the back of the modules is more or less thermally insulated, this should be lowered, theoretically up to half the value (i.e. the back side doesnt participate anymore to thermal transfer). Determination of the parameters The determination of the parameters Uc and Uv is indeed a big question. We have some reliable measured data for free mounted arrays, but there is a severe lack of information when the modules are integrated. What value should be chosen according to the air duct sizes under the modules, and the length of the air path? One can observe that the heat capacity of the air is very low. Even with large air vents, the flowing air under the modules may quickly attain the equilibrium with the modules temperature at the end of the duct, leading to no heat exchange at all. Therefore for the top of the array the U value may be the fully insulated U-value; you can have big differences between the regions of the array near the air input, and at the output. The program doesnt take this inhomogeneity of the array temperature into account. On the other hand, the use of the wind dependence is very difficult. On one hand the knowing of the wind velocity is extremely rare. On the other hand the meteo wind velocity (taken at 10 meter height) is not representative of the temperature at the array level (there may be a factor of 2 between them). In this respect the Uv value is obviously not the same for these two definitions of the wind velocity. Default and proposed values The default value is fixed for free-standing arrays, as: Uc = 29 W/m ²Ã‚ ·k, Uv = 0 W/m ²Ã‚ ·k / m/s If you have fully insulated arrays, this should be halved: Uc = 15 W/m ²Ã‚ ·k, Uv = 0 W/m ²Ã‚ ·k / m/s These values suppose an average wind velocity of around 1.5 m/sec at the collectors level. In very windy regions (larger average wind velocities), you can increase the values; but we cannot say by which amount in a reliable way. NOCT Values Some practicians and most of PV modules catalogues usually specify the NOCT coefficient (Nominal Operating Collector Temperature), which is the temperature attained by the PV modules without back coverage under the standard operating conditions defined as: Irradiation = 800 W/m ², Tamb=20 °C, Wind velocity = 1 m/s, Open Circuit. The NOCT factor is related to loss factor U by the thermal balance (from the expression of the top Alpha  · 800 W/m ²  · (1 0) = (Uc + Uv  · 1m/s)  · (NOCT 20 °C). In the definition dialog, the user may define either the U factors or the NOCT. The program immediately gives the equivalence (using Alpha=0.9 and Effic = 10%, without wind dependence). Ohmic wiring losses Ohmic Loss Ratio The Ohmic Loss ratio is referred to the PV array at standard conditions (1000 W/m ², 25 °C), It is the ratio of the wiring ohmic loss Pwir = Rwir * Isc ² compared to the nominal power Pnom(array) = Rarray * Isc ² (SC= short circuit). Where: Rarray = Vmp / Imp at Standard Test Conditions (STC) Rwir = global wiring resistance of the full system. This is computed for a given sub-array as the resistance of all strings wires in parallel, in series with the cables from the intermediate connexion box on the roof to the inverter input. The global wiring resistance Rwir is obtained by putting all the sub-array wiring resistances in parallel. Use in the simulation The Global wiring resistance value finally used during the simulation may be defined here: as an Ohmic Loss ratio (the default value is 1.5% at STC) or given explicitly in mOhm. Wire diameter optimisation and Wiring Resistance Wire sections are determined by the maximum allowable current and the ohmic resistance. Here the proposed diameters are automatically limited to the minimum allowable section, according to the European standards for isolated wires mounted in apparent mounting ducts. Now for a given global loss target (at STC, i.e. maximum operating current), the best section choice is determined by the program in order to minimise: The global copper mass, The ohmic losses behave in a quadratic way with the array current (Ploss = R  · I ²), so that the ratio diminishes linearly with the output current. Therefore the average wiring losses are much lower during the whole running year. Metal resistivity The resistivity of wiring metals is strongly dependent on the temperature, which can widely vary due to dissipating currents. For pure metal, one has: Copper: Rho = 1.68 E-8 * (1 + 0.0068 * Temp [ °C]) [Ohm ·m] Default value: Temp = 50 °C => 22 mOhm ·mm ²/m Aluminium: Rho = 2.7 E-8 * (1 + 0.0043 * Temp [ °C]) [Ohm ·m] Default value: Temp = 50 °C => 33 mOhm ·mm ²/m We use copper which have minimum resistivity. Module quality losses / mismatch Module quality loss It is well-known that most of PV modules series dont match the manufacturer nominal specifications. Up to now, this was one of the greater uncertainties in the PV system performance evaluation. Now, with guaranteed power statements and increasing availability of independent expertise, the situation seems going toward some clarification. Module series are sold with a given tolerance, and actual powers usually lie under the nominal specified power, but stay in the tolerance. We decided that the program default was acceptable. Array mismatch loss Losses due to mismatch are related to the fact that the real modules in the array do not strictly present the same I/V characteristics. The graph below helps for visualising the realistic behaviour of such an array, with a random distribution of the characteristics of short-circuit current for each module. This allows for the quantification of power-loss at the maximum power point, as well as of current-loss when working at fixed voltage. (MPP= maximum power point) Array incidence loss (IAM) The incidence effect (the designated term is IAM, for Incidence Angle Modifier) corresponds to the weakening of the irradiation really reaching the PV cells surface, with respect to irradiation under normal incidence. In principle, this loss obeys Fresnels Laws, (They describe the behaviour of light when moving between media of differing refractive indices. The reflection of light that the equations predict is known as Fresnel reflection), concerning transmission and reflections on the protective layer (the glass), and on the cells surface. In practice, it is often approached using a parameterisation called ASHRAE (as it has become a standard in this American norm), depending on one only parameter bo: FIAM = 1 bo  · (1/cos i 1), with i = incidence angle on the plane. For single-glazed thermal solar modules, the usually accepted value for bo is of the order of 0.1. But in a PV module, the lower interface, in contact with the cell, presents a high refraction index and our specific measurements on real crystalline modules actually indicate a value of bo = 0.05.

Planning and Measuring Performance Essay

Planning and Measuring Performance Planning and Measuring Performance This paper will discuss Hospital Corporation of America’s (HCA) goals of achieving industry-leading performance in clinical and satisfaction measures and recruiting and employing physicians to meet the need for high quality health services (University of Oregon Investment Group, 2011). This paper will also discuss which tools would be most effective in measuring the organization’s performance against the determined standards. The actual standards that HCA would use to measure the first goal of achieving industry-leading performance in clinical and satisfaction measures are set by The Joint Commission. According to Kicab Casta eda-Mendez (1999), achieving improved clinical performance and satisfaction measures requires performance measures in three areas: * To lead the entire organization in a particular direction. * To manage the resources needed to travel in this direction. * To operate the processes that make the organization work. According to Kicab Casta eda-Mendez (1999), these measures are: * Strategic–to drive strategies into action and change the organizational culture. * Diagnostic–to evaluate the effectiveness of these actions and the extent of change. * Operational–to improve continuously. The most effective tool to measure these improvements is benchmarking. Benchmarking against the top healthcare companies will determine if HCA is achieving industry-leading performance in clinical and satisfaction measures. Without benchmarking HCA could not determine if the company was leading the industry or if they were at the bottom of organizational ladder. HCA’s goal of hiring physicians to meet the need for high quality health services can be measured by determining the number of physicians need to accommodate the number of patients, determining the specialties/ sub-specialties the physicians are needed in, as well as measuring the retention rate of the physicians. The Balanced Scorecard would best fit this goal. The Balanced Scorecard allows the company to see the projected percentages and the actual percentages of the measurements. It also helps the company see what needs to be changed and gives direction for those changes. HCA can use benchmarking and the Balanced Scorecard to measure the different aspects of their goals. HCA will also be able to see the areas that need improvement and have some guidance into making these changes. With these tools HCA will be able to make an effective go at achieving their goals.

The Development of Wave Energy in China

Introduction With the growing concern over the emission of greenhouse gas and the depletion of fossil in roughly a hundred years (Guo, 2010), greater emphasis are placed on the utilization the renewable clean energy, such as solar energy, wind energy, hydro energy, biomass energy. Wave power, as one of inexhaustible clean energies, stands out prominently due to high efficiency and low capital cost. As a result, Sea wave power has been increasingly viewed in many countries as a competitive and promising energy resource(You, 2003).China’s engagement in the study of wave energy conversion since 1970’s has made significant progress in fueling China’s fast growing economy. And there is still great potential of further exploitation of wave energy as about 7? 1010 W of wave energy is technological accessible in the near shore of China. Development and deployment of wave power help phase in the energy structure swift ‘from coal-dominance to more shares of clean energy typesâ₠¬â„¢ to tackle the problem of energy crisis and environmental pollution in a cost-effective manner (reference from Beijing Foreign Affairs Office).This term paper focuses on the conditions, progress and challenges of utilizing wave energy in China. Firstly it discusses the physical concepts of sea wave energy, including the basic process, relative merits and several common converters. The main part then elaborates on the reasons and situations for China to exploit wave power. It finally concludes from the progress of utilization that wave power has a vast developing foreground and an infinite market potential in China. Physical Features of Wave PowerAs one of the mechanical waves, the ocean waves are generated by wind blowing vastly enough over the sea surface and transferring energy from wind to wave(Guo, 2010). Specifically, the formation of waves is due to ‘the tangential stress on the interface between the wind and sea’(Guo, 2010), intensified by ‘the wind blo ws on the upwind side of the wave which cause pressure different between upwind and downwind of wave(Guo, 2010). While energy transformation takes place in macrocosm and transverse aspect, changes of energy magnitude exist in microcosm and longitudinal regard.Under the action of wind and gravity, the particle moves in circle in deep water while moves elliptically in shallow water. Dimensions of particle trajectories decrease exponentially as the depth increase in both deep water and shallow water(Guo, 2010). Typically these paths will become very small at a water depth larger than a few wavelengths in the deep water (Chow, 2012), which means that the larger orbits on the sea surface contain more wave energy than those in the deeper location.Consequently, ‘the wave energy is stored in the ocean worldwide and highly concentrated near the ocean surface’(Guo, 2010). The above-mentioned kinetic energy and potential energy generated by sea surface waves is referred to as ocea n wave energy(â€Å"Wave Energy Development,† 2006). Huge amount of energy is stored in waves, consisting of 94% energy of the ocean stored in the waves and the other 6% in tidal energy(Guo, 2010). Generally speaking, wave power cannot convert to electricity directly like wind energy. Wave energy should first be captured and converted into useful mechanical energy and then use this form of mechanical energy to generate electricity’(Guo, 2010), which might cause energy loss during conversion. Three determinants of energy output are wave height, wave speed, wavelength, and water density. †¦ Relative Advantage and Disadvantages The technology of producing electricity from sea waves is innovative and a leading method worldwide.Environmental pollution and global warming as a result of fossil fuel consumption have turned people to make use of largest world resource to create electricity, namely, sea waves. Comparing with other renewable clean energies, wave power has re lative high-lightened merits as follows(Kloosterman, 2010): High Density Wave power is the densest power among renewable energy resources, namely about 5kW/m to 100kW/m(Guo, 2010). The high density of wave power implies that considerable amounts of electricity may be yielded at relatively small sites. Certain ContinuityThe second feature that makes wave power suitable for electricity production is that the wave power can produce electricity continuously Unlike most of renewable energy resources (Guo, 2010). By contrast, nuclear power plants and hydroelectric stations are hi ghly susceptible to earthquake damage and China is hit by more than 4 typhoons a year on average, making the building of wind farms extremely difficult but wave electrical devices promising(Aviv, 2008). High Efficiency Besides high density and continuity in production, wave energy also is characterized by its high efficiency.According to S. D. E, wave energy has the potential to provide 4 times more energy per sq uare meter than wind, leading to rendering 500 times more than the electricity requirements of the whole world population if fully harnessed which ‘offers a solution to the severe global shortage of electricity that is estimated to cost billions of dollars’(Aviv, 2008). Multi-purpose Utilization Plenty of other purposes can be realized by wave energy besides providing electricity. The low temperature water in deep seas can replace Freon for the refrigeration of air-conditioners in summer.Desalination of sea water on islands lacking of fresh water can also be achieved by wave power. As with You (2003), ‘Multi-purpose utilization of wave energy can increase its commercial values’. Some Drawbacks As a rather new field with most of the technology under development, the practical efficiency of the wave power device is not high enough. Basically, wave power is ready to be used at low speed and high force and the motion of forces is not in a single direction, rais ing difficulties for most electric generators that operate at higher speeds and turbines that need a constant, steady flow(â€Å"Powered by the Sea,†).Conversely, the cost for construction is high. Since the devices used for capturing the sea waves, ‘the structure need to be withstanding the rough weather and the corrosive sea water’(Guo, 2010). ‘The total cost includes the primary converter, the power take-off system, the mooring system, installation and maintenance cost, and electricity delivery costs(â€Å"Powered by the Sea,†)’, boosting costs of generation in this way.Also, the wave power electricity generation is highly dependent on the sea characteristics, putting limits of the construction of wave power devices exclusively to the high wave power density coastlines(Guo, 2010). Moreover, wave electricity devise can exert potential negative influence on the marine environment. Large-scale implementation of wave energy converts (WECs) is l ikely to introduce an anthropogenic activity in the ocean(Patricio, 2009). This in turn may contribute to underwater noise which is detrimental to certain marine fauna with acoustic sensibility.Proper and continuous monitor of the noise can help abate the negative effect on marine species. Consequently, the advantages of wave energy far outweigh its drawbacks which mostly can be mitigated with further technological development. Potential Worldwide and in China ‘The realistically usable worldwide resource of wave energy has been estimated to be greater than 2 TW’, equivalent to an annual amount of 6000TWh(Wikipedia). The practical potential to harness the wave power to generate electricity would be much less given some constraints like technical and economic difficulties(Guo, 2010).Waves generate approximately 2,700 gig watts of power. According to Wikipedia, of those 2,700 gig watts, only about 500 gig watts can be utilized with the technology currently. This huge poten tial and applicability of wave power concentrate especially on the regions along coastlines, including the western seaboard of Europe, the northern coast of the UK, and the Pacific coastlines of North and South America, Southern Africa, Australia, and New Zealand(Wikipedia).South-eastern China has an obvious comparative advantage in regard of wave resources, with excellent conditions for mineralization, and there are 130 types of minerals with proven reserves. Recent Progress of utilization of wave power in China Although the first known patent on wave energy conversion was issued as early as 1799, extensive researches have not been carried out until the early 1970s(â€Å"Wave Energy Development,† 2006). Extracting the power of the waves is ‘moving out of the realms of sea mythology and into scientific reality’(â€Å"Powered by the Sea,†).Representative countries that pioneered in this field are United Kingdom,Norway,Portugal,China,India and so on(You, 200 3). ‘Various kinds of wave energy conversion devices have been proposed and many prototype wave power stations have been constructed, such as Salter duck, clam, Cockerel raft, oscillating water column (OWC)(You, 2003). ’ Had it not been due to certain technical and economic constraints, the huge reserve of power stored in oceans covering 71% of the earth’s surface is bound to have a promising foreground.For example, most of the studies on other influencing devices have been called off in light of low conversion efficiency and poor sustainability, leaving the OWC system of wave energy conversion to be the major direction of researches(You, 2003). Therefore, wave power generation is not currently a widely employed commercial technology comparing with other renewable green energies(â€Å"Powered by the Sea,†). In tune with the world trend, China is in the first rank of countries in studying wave energy conversion at present with a history also dated back to 1 970s. Actually, the application of wave power in a real sense started in 1982(Guo, 2010).Developments in establishing small marine wave power devices like lighthouse or small power devices equipped in ships laid foundation for the completion of the first wave power station in 2005 with capacity of 50kW and yields roughly 26MWh every year(Guo, 2010). The next milestone is also established in 2005 which is the largest wave power station in china with capacity of 100kW. Both of the power stations are located in the southern province Guangdong with 4,300 km in costline. China has established Department of Energy in 2009, and will focus on development of renewable energy include wave power.Glorious past contributes to the present development of wave energy in China. It is one of the most influencing countries in studying wave energy conversion at present. Up to now, three types of facilities utilizing wave power have been developed, including shoreline OWC wave power plants, floating OWC buoys and pendulous wave power plants(You, 2003). Besides, one of the two power plants in Guangdong province is under construction with 150kW capacity and the other one of 500Kw capacity is planed to start in the near future(Psenak, 2012).A third plant was built in Yangjiang City in 2011. Applicability of different wave power technologies in China can be summarized into five kinds, that is Oscillating water column(OWC), Pelamis wave power converter, Oyster wave power conerter, wave dragon converter and Finavera wave power converter(Guo, 2010). The main disadvantages with OWC are low efficiency and high capital cost, which canbe addressed with the development of OWC technology. According to the Chinese wave power company, the estimated total efficiency of the OWC system can reach 20%(Guo, 2010).Although covering the shortages of OWC, Pelamis wave power convertor with long and narrow (snake-like) shape pointing into the waves, is not suitable for China as it can only be applied to hi gh power density area. The same situation applies to the Finavera power converter. The Oyster system ‘consists of a hinged mechanical flap connected to the seabed at a depth of 10 metres. Each passing wave moves the flap which drives hydraulic pistons to deliver high pressure water via a pipeline to an onshore turbine which generates electricity’(â€Å"Powered by the Sea,†).Unlike Pelamis wave power converter, ‘Oyster wave converter has relative low limitation in wave power density and it is near-shore fixed in shallow water’(Guo, 2010). Moreover, the capital cost of Oyster wave power convertor is lower than OWC systems. It is considered suitable for China, according to Guo(2010). The wave dragon technology is not mature enough to be put into practice in full size. †¦ The future of wave power in China Chinese policy is open to developing comprehensive renewable energy resources, including wind power, solar power and wave power.Although wave powe r is currently the least used in China, it is widely believed that wave power has a big potential because of some advantageous natural conditions(Guo, 2010). †¦good wave climate in Guangdong, Fujian and some other provinces. The potential capacities of wave power in China are 500GW approximately(Liu). Wave energy is considered to be the large useful wave power resource in China. The technologies of wave power have been developed for a long time, though not very mature due to the high cost of the existing wave power plant.Continous experiments with new equipments to harness ocean wave energy as well as efforts to attract sizeable foreign investments would be the major goals of this giant developing country(â€Å"Wave Power Projects in US, Scotland and China â€Å", 2010). It is reasonably estimated that the cost for wave power generation will decrease to a rational level if wave power is largely used for commercial generation(Guo, 2010). As analyzed preceedingly, the on land O yster systems suit China best and improved OWC will be the most widely adopted wave power generation system in China.According to Guo, ‘if they are combined with newer systems off-shore wave power generation system such as Wave Dragon and Pelamis, these will form the future Chinese wave power generation system'. In this way, the time volatility of wave energy can also be smoothed by interconnection of large numbers of devices(Falnes, 1991). Hence, wave energy is expected to have a great potential to be economically competitive with the development of new designs and technical improvements over time(Falnes, 1991).Establishing, operating and maintaining the convert facilities of wave energy is set to provide a major boost to coastal societies for the country.
