Philosophy and Religon Essay - 1286 Words

The 16th century was a time of culmination. A time during which the fundamental forces of civilization that shaped the world thus far, came together and accelerated their pace. Religious, cultural, intellectual, and economic transformations took place. New civilizations arose, only to be destroyed by imperialistic invaders. Old cultures converged and conflicts arose. New and old, east and west were unified, if only fleetingly and superficially. The religious beliefs of any society during the 1500s were taken very seriously and were tremendously important. At the time, entire empires were built on the simple principle of religion.

Their God was not a removed entity that controlled the world but did not have a role in the life of the individual. Their God was everything and without him, there was nothing. God was salvation and eternal life. Their main reference was the Bible. It was studied extensively by Catholic theologians and, from it, created a central ethical system was developed. The Chinese on the other hand had an ethical system based on the individual. Confucianism was not a religion. It was not based on a deity and strict codes of conduct found in Catholic tradition did not exist. However, an overall sense of order was decidedly central to its philosophy. Virtue here was found introspectively, through thought and study. Another interesting facet of Confucianism was it’s veneration of ancestors, an extension of honoring one’s parents. These two ethical systems differed so much that fundamental concepts (right, wrong, sinful, virtuous) were not completely equateable. Confucianism viewed people as fundamentally good. In the Great Learning, a fundamental Confucian text, described human nature as â€Å"being universally good† and that the â₠¬Å"original substance of the mind is correct.† This gives us important insight into how they would classify an act as immoral or sinful.

Accounting Theory Concepts with Critical Analysis

Question: Discuss about theAccounting Theory Concepts with Critical Analysis. Answer: Introduction of Accounting Theory Concepts Accounting theory concepts are referred as doctrine or elementary accounting postulates. These concepts can be said as rules implement as guides to actions. A concept is general and recommends a guide. There are many probable events in accounting but rules could not be approved for every conceivable ultimately (Hub Pages, 2011). Some significant accounting concepts are as follows: The Accrue Concept: According to accrue concept, profits acquired by conducting events are affects only to the equity of owner. It specifies that the profits should be recorded when sales occurred, whether cash from sales due accrue or is in arrears. It can be said that it is same as matching concept of accounting. Expenditures are also concurrently known at the time of event conducted and it is not compulsory to know at the time of cash paid. This concept holds that revenue which was earned and cost which was incurred that produces revenue have to be match and reported for the accounting period. Business Entity: Business and owner of business are different so all the transactions which occurred in business can be documented as they affect the business and are different from the owner. But in the case of company, difference can be maintained easily. Because under companies, laws and rules follow according to the business and company has its own personality. Company can sue by its own name in place of sue by name of all its owners or shareholders because company has its own existence. Company is treated as entity with separate existence from the proprietary business. Quantifiable / Money Measurement: This concept says that under accounting, every item should be assessable in terms of money (i.e. in cent and in dollar). Each item in accounting should be placed in the terms of money. The cause behind it is that money can be accepted in value and as medium of exchange. Duality: It is based on the principle of book keeping of double entry system. Each transaction occurs by debit and credit items. For example, if an asset purchased in cash then asset will be debited or cash will be credited. As per double entry system, each transaction affects two items. Periodicity: Generally, accounting period is of one year, although for the purpose of management, some time reports are prepared for short period of time which is known as interim statements. Until the final liquidation of business, the results cannot be measured appropriately. So, accounting period of one year is used to measure or evaluate the changes in financial position of business. Realization: Under this concept, revenue recognized in an accounting period is discussed. The four categories of realization are as follows: Revenue can be identified at the time of scale Revenue can be identified during production period Revenue can be identified at the time of production is completed Revenue can be identified consequent to the sale (for example, at the time of collection of cash). Revenue can be recognized at different points of time. For example, at the time of production of goods, at the time of delivering the goods, or at the time when transaction is completed. In most of the cases, choice depends on norms of industry. Historical: The concept of historical cost tells that the base of accounting recognition of all asset attainment, providing or receiving services, incurred expenses and all other transactions is cost. So this concept refers that acquisition cost of assets are maintained throughout the process of accounting (Miss CPA, 2012).

What Would You Do When Confronted with Injustice free essay sample

One example of a social injustice is when a person commits a crime for the first time or gets in trouble with the law for the first time, gets prosecuted to the fullest but a person who is a convicted criminal keeps getting away with the crimes they are committing. Social injustice continues to resurface all around, taking new forms as society grows and changes. In the book Of Mice and Men, by John Steinbeck, George, Lennie and Candy, are constantly working towards conquering their dreams and are held back by Curleys selfishness. A few example of social injustice is racism and sexism. Racism is shown when the white men shun Crooks for being an African-American. They treat him differently and make him sleep in a barn away from all the other workers. This still goes on in our society today. Sexism is an important theme in the book. It is also an injustice where the workers mistreat Curley’s wife because she is a female. We will write a custom essay sample on What Would You Do When Confronted with Injustice or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page The workers call her a â€Å"tramp† and many other vulgar names because she wears red shoes and is the only female character in a male-dominated story. Another category that would fall under injustice is discrimination against Homosexuality. One of the biggest social injustices going on in the world today is the discrimination against gay and lesbian individuals. For a long time in many (but not all) societies, homosexuals have been persecuted, physically attacked, denied rights to housing, jobs, love and most other things that a good society offers merely because of their orientation. We have â€Å"Gay Pride† because it is necessary for homosexuals to express the pride they have in themselves as individuals. Everyone has a right to have pride in their selves. I have a gay friend who gets bullied every single day for being a homosexual. I’ve watched kids taunt and bully him for years, at school and outside of school. I do the best I can to stand up and be there for him but since he came out of â€Å"the closet. † Hes has been very lonely and quiet and not himself anymore. Also, he has been isolating himself from people close to him, including parents, and I sometimes get scared of what might happen to him if his emotions get the best of him. I sometimes call him at night just to make sure hes fine and when I call him sometimes he would break down and then I would cry because it just breaks my heart knowing someone I love is like this. I know this isnt something you can get over so quickly, but I just cant stand seeing him like that. I dont know what else I can do for him, apart from just being there for him. Does this make you angry? I do feel angry about injustice and I believe that people have been and will continue to be subjected to injustice in most societies. The result will be that many people will feel bad about themselves. The only way to fix an injustice is to learn from the mistakes and act upon them as they are presented in the future. If I was confronted with an injustice, I would do the same thing I did for my friend as I would for myself; stand up against it. I would never allow somebody get in my head and tear me down. With all of the past bulling, it has made me the strong young lady that I am today. I like to stand up for my beliefs. Even if nobody approves of my beliefs, the hold the right to formulate their own opinions and to honor mine. People learn and grow through past experiences and those have definitely outlined my beliefs today. Social injustices will be around forever. It is up to us to learn from them.

Human Resources Management in Business free essay sample

Human resources department is a part of business that deals with its staff. The department is seen as part of strategic management, in the effort to achieve the goals of the business, and is crucial to the businesss success. Some of the human resources departments responsibilities include recruitment, retention, selection, job enlargement/enrichment, motivation and leadership, job role allocations, training, and payroll appraisals. The departments decisions are influenced by, however, internal issues for workforce planning. One of the issues could be the cost of its operations. The business would want to minimize cost, so any decisions made by Human resources should be cost-effective. Another issue could be the companys business strategy, for example when the company want to expand, the Human resources department would have to recruit more employees; if the company wants to cut costs and increase profit, the department would have to consider reducing the number of staff. We will write a custom essay sample on Human Resources Management in Business or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page It is also responsible for training current employees for any new equipments. There are also external factors that affect how workforce planning is carried out. These external factors include government actions that affect the business environment. For example, the government can impose new minimum wages that would increase the Human resources departments spending on wages payment. The education situation of the country can also affect Human resources, as education is the means that workers gain their skills; without proper education, Human resources wouldnt be able to recruit highly skilled workers without paying large salaries or recruit foreign nationals. An important external factor is the economic situation of the economy. If unemployment rates are high, Human resources would be able to recruit new employees much easier and cheaper than when the economy is in boom, which makes labour more expensive. The age ranges of the labour force can affect Human resources decisions, since they dont want to recruit too old of employees who are going to retire soon. The business often want more young employees who can potentially contribute to the company for a long period of time, and can also be more innovative. Another external factor is technology advancements, as this may result in the introduction of new equipments into the company. The Human resources department would then have to organise training for their current staff to enable them to work with the newly acquired machineries. There are many benefits to Human Resources planning. One of the most important purpose of the Human Resources department is to motivate staff. This can be done by means of promotions, training, and rewards. Another benefit is that Human Resources help import important skills into the business through the process of recruitment. Human Resources would compose a recruitment process that selects the right people for the business. Without a Human Resources department, a firm cannot efficiently recruit employees that they need. Also, the department helps the business plan the right number of workers. They make sure that there are no redundancy or shortages of labour in the company, and if there is any, Human Resources would fix this either by cutting or recruiting staff. Human Resources department also ensures smooth operations in regards to labour management. This means they make sure that employees arrive when they are needed, and are allocated to the right tasks, and that each workers know their role within the business. In addition, they resolve whatever arguments that may arise between the workers and company management, making sure that the employees are clear of company regulations, and that management are clear of their workers conditions. Finally, the Human Resources department ensures that no laws are broken in regards to labour employment. For example, the recruitment process must not violate discrimination laws. All necessary laws are briefed to staff to ensure no illegal activities are conducted within the company. Before selecting staff for any position, key skills needed for that particular job need to be identified, creating a list of criteria for candidate selection. British Sugar is one of the largest provider of sugar products in the UK. Their Human Resources department has been directed to recruit three new production managers, as part of the companys expansion project in China. The Human Resources department has identified the key skills for a potential production manager: Confidence: the manager needs to be confident in handling large responsibilities, whether it be meeting production deadlines, ensuring worker safety etc. They need confidence to be able to make decisive actions, taking the initiative without too much dependence on higher directives. As they direct the production process, confidence is also needed for negotiating with suppliers, making the best deals for the factory. Technical skills: a production manager has to be sufficiently knowledgeable about the production technology of their factory, to be able to understand and resolve technical problems should they arise. Technical knowledge of a manager does not have to be detailed, but must be sufficient to issue correct directives to the factorys engineer force. High technical skills is preferred, as the manager will be more likely to be innovative in improving production methods of the firm. Communication skills: a good production manager is able to communicate to all different divisions of the company. They are quick to absorb information from different levels of the company, whether it be top management or floor workers, and then provide quick and effective feedback. Communication skills are crucial in a manager, as it helps him ensure the coordination between different elements of the company. Problem-solving skills: the production manager should be able to independently deal with problems within their factory. They will be extremely resourceful in coordinating factory or company-level efforts to solve problems. This requires an intelligent person that can improvise upon their resources to damage-control and reverse the problem and put the factory back onto its original course. Motivating staff is an important part of company operation, as it ensure the employees do their best and be productive while working for the company. There is a variety of reasons why employees would want to work harder in their working environment. Such reasons could be money, bonuses, power, working with friends, social aspects of work, the need to provide for family, promotion, team work, and promotion. Frederick Taylor’s theory of motivation simply stated that all workers are worked by money. This means that in order to better motivate employees, the employer simply just has to raise their pay, and this would make them work harder. Taylor introduced the Theory of Scientific Management, which said that workers are naturally lazy and need close supervisions and control. The theory also says that managers should break down work to the simplest tasks to their employees. Workers also need adequate training and equipment to perform their simple tasks as efficiently as possible, then they would be paid according to the amount of products they had produced. The theory is often applied in mass production lines which involves repetitive tasks. Elton Mayo later introduced a new theory of motivation of his own. He believed that money is only part of the worker’s concern, and social needs are more important in motivating workers at their work place. Mayo published the Human Relation school of thought, which encourage managers to focus more on social interactions between workers. Mayo went further in his studies and conducted his own experiment at the Hawthorne factory in Chicago. From these series of experiments, he concluded that although physical conditions worsened, they do not affect the productivity of the Hawthorne workers. Instead, social factors such as better communication between workers and managers, better involvement in employees’ lives from their manager, and team work was what improved productivity levels. In the 1950s, Abraham Maslow introduced the Neo-Human Relation school of thought. This new theory focus on the employee’s psychological needs, which are structured into five different levels of needs. The theory says that once a lower level of needs is satisfied, would then the worker could be motivated by an upper level of needs. These levels of needs in lower to higher order are physiological needs, safety needs, social needs, esteem needs, and self-actualisation respectively. Managers also need to realise that each worker moves up this ladder at a different pace, and therefore might need different sets of incentives from worker to worker. In financial-related type of motivations, the most common motivation is salaries and wages. Salaries are what permanent employees are paid monthly or annually. Wages, on the other hand, is what is paid to workers per hour they have worked. These can motivate the employees, for the harder they work, the more they would earn. A piece rate system is when an employee is paid a fixed rate for each unit of production; In other words, they are paid by results, which motivate them to achieve better results. Commission and fees are similarly dependent on the results of the workers. Commission is a percentage of the sale revenue, and fees are fixed amounts that are earned after sale. The more the employee sells, the more commission or fees they get, motivating them to sell more. Fringe benefits are any non-wage payment or benefit such as pension plans, profit-sharing programs, vacation pay, and company-paid life, health, and unemployment insurance. Having these extra benefit with their jobs can make the employees feel more secure and work harder. Performance-related pay or pay by performance is money paid relating to how well the employee works. This would motivate them by giving them knowledge that the better they perform in their field, the better their assessment would be and the more they would be paid. Profit sharing is another way of motivating staff, it consists of a plan that gives employees a share in the profit of the company. Each employee receives a percentage of those profit based on the companys earnings. This makes staff work harder, knowing the more their company earns, the more they would get in shared profit. Share ownership is when employees who have worked in the company for a long time are given part of the business as shares. These shares would give the employees power, and they get to take part deciding how the company is run. Other than financial motivations, there are non-financial ones that could boost motivation while costing minimal for the business. Job redesign involves restructuring the elements including tasks, duties and responsibilities of a specific job in order to make it more encouraging and inspiring for the employees. Job enlargement is basically increasing the employees work load, so that they feel more responsible and work harder. Job rotation is when employees are moved between two or more jobs in a planned manner. The purpose of this is to expose the employees to different experiences and wider variety of skills to enhance job satisfaction and to cross-train them. Job enrichment is a variation of job enlargement. Job enrichment adds new sources of job satisfaction by giving the employee additional authority, autonomy, and control over the way the job is accomplished. Team work is a Cooperative effort by the members of a group or team to achieve a common goal. Working in a team may motivate employees to do better to fulfill their part on the team. External link for employees motivating can be found here: http://www. forbes. com/sites/glennllopis/2012/06/04/top-9-things-that-ultimately-motivate-employees-to-achieve/ The fundamental method which British Sugar would use to motivate their staff is to make them feel safe. Feeling safe would clear the employees minds from external worries, helping them to focus more on their tasks and try harder to achieve. This method would include providing their employees with adequate facilities to work in. This means that British Sugars factories and offices would to the most basic safety regulations such as fire safety, electrical safety, and protection from hazardous conditions inside their factories. British Sugar would also make sure that their facilities have appropriate security measures to protect employees and their possessions safe. This method of motivation is one of the most basic levels of Maslows hierarchy of needs. Another method that British Sugar uses is providing extra employee benefits beside their regular salaries and wages. They would give company cars for manager and directors, along with free O2 mobile phones. British Sugar also looks after their employees by providing them with free healthcare in the form of free check-ups with company nurse, eyesight tests and glasses, and subsidised scheme with AXA. Families of employees can also enjoy company benefits with provided child vouchers and team meals for spouses. British Sugar’s factory workers are also provided with free safety work wear. There are numerous other benefits that employees can enjoy working for British Sugar, which includes sports clubs, gym facilities, free parking†¦etc. A popular method of motivation from Taylor’s school of thought is recognition. British Sugar would give out tokens of appreciation and to recognise employees/teams that have made a significant contribution over and above that reasonably expected. Company managers would award their employees with vouchers, meals, bouquet of flowers, or bottles of wine to boost their work morale. Long Service Awards are given to employees with significant length of service. Annual bonuses of ? 400, ? 600, ? 800, and ? 900 are given to employees who have served 20, 30, 40, or 45 years in the company respectively. British Sugar also use chances of promotion to encourage their employees. This is a process known as internal recruitment. When a position is open, employees are often promoted to fill the position instead of recruiting new people externally. This keeps the employees motivated to work harder, knowing there are chances of future promotion. Another method of motivation used by British Sugar is performance management. Performance management is a proactive and continuous process of communicating and clarifying role responsibilities, performance expectations and priorities in order to ensure mutual understanding between managers and employees. To ensure the proper functioning of the business, British Sugar would have to maintain a high level of cooperation and satisfaction in its employees. Making employees cooperate would increase productivity, reduce labour turnover, and make sure that they can maintain the quantity and quality of work they are capable of. One of the methods of doing this is by communication. This method involves staying in touch with the staff to make sure they are updated with company information. When staff have the information that they need for their job, they will be more likely to be oriented towards their tasks, and be able to do it correctly and more efficiently. Communication with employees can be done by many means. It includes emails, which are quick, efficient, and reliable. Face-to-face communication is an important form of communication, often in the form of meetings; however it has time and distance limitations , for example a manager might not have the time to see all of his employees to talk about new policies, while he could just send them all an email. There are other methods such as telephone calls, which can be made easily over long distance or face-time technology that allows employees to communicate despite the long distance. Another way of improving employees cooperation and commitment in the business is making them more involved in it. In British sugar, this is know as the â€Å"quality circle†. British Sugar would engage its employees group discussions, where groups of workers meet and discuss the good and bad side of the issues that they face. The employees would try to resolve their problems together, and discuss ways to improve how they work and how the company works. This method generates a feeling of involvement, employees would feel that they are a contributing part of a team, and therefore view their work more positively and become more inclined to cooperate with other employees as well as the company managers. Clear employment contracts also help boost staff cooperation and commitment. A clear contract would have to explicitly explain the details of the job, such as explaining the roles and duties that the employee is expected to carry out, along with the hours of work required. The business would also need clearly identified procedures such as disciplinary policies or grievance policies. A clear pay structure that explains basic time as well as overtime is essential. All of these will reduce arguments in the company, enabling more efficiency and cooperation within the business. Motivational methods are a way of getting more cooperation from staff. Motivated employees would perform better while feeling better about their prospects than demotivated ones, therefore cooperating more in their work. Similarly, training and charity links should also be used to boost the morale of workers. Training would increase the employees motivation and performance, as well as charitable activities such as helping out the local community. A well-motivated workforce with high morale is more likely to cooperate with the company and to each other. The culture of the business itself will also affect how its employees cooperate. If the company has a culture of cooperation and an atmosphere of teamwork, then the employees are more likely to have more cooperation in their work. Training in a large organisation such as British Sugar is carried out extensively. An example of British Sugars training operation is their Graduate scheme, a scheme in which British Sugar finds apprentice in universities. The company would offer university graduates a period of vocational training, with the assurance of a job at the end of their training, in addition to have year-long job placements for engineering students. British Sugar also organises over 1000 training courses every year involves all levels from senior managers to new apprentices and our seasonal workers. The company encourages its sites to play an active role in local communities through media visits, schools activities, agricultural and environmental events. British Sugar have regular dialogues with leading and local non-government organisations. They also organise sponsorships and charitable funds, allocated to their employee fundraising activities through a Supporting YOU to support others programme. Measuring the workforce can be done by a number of ways. This is generally looking at the key indicators in the business workforce such as labour productivity, health and safety, labour turnover and absenteeism. Labour productivity is how much the workers produce in terms of goods and services per hour worked. In the business, it can be measured by looking at the efficiency of individual or teams. However, this method should be used with cation, because there are factors that could affect labour productivity such as the age of machinery, type of sector that the business is in or whether production is automated or labour-intensive. If machineries are old, they wouldnt be able to produce as much, therefore being the cause of low labour productivity. A business in the secondary sector would be more productive than one in the tertiary sector since manufacturing makes more products than service. Similarly, a business that has automated production will be much more productive than one with labour-intensive production, since machines are able to mass produce more products than individual workers. A business can try to improve labour productivity by using motivational tools such as bonuses. Training can also be used to add productivity to workers, and business plans help staff work more efficiently. The business can also buy new equipments to improve productivity of their workers. Another measurement is health and safety. As it is one of the motivational factor, the quality of health and safety at the workplace can affect the staff. The better the health and safety standard, the better the staff will perform. The business must consider the possible causes of poor health and safety, such as poor equipment, dangerous environment and also the poor training in the matter. Labour turnover can also be used to measure a companys workforce. Labour turnover is the proportion of staff leaving the business over a period of time, usually each year. A company can lose their staff due to de-motivation, retirement, social factors, better opportunity elsewhere ,or that the employee wants to start their won business. Staff leaving can also be involuntarily as their positions become redundant or they are fired due to performance. A high labour turnover is generally not good because it spawns many problems such as the loss of productive capacity, the costs and the time taken to recruit new staff, and the extra training and induction programmes to new employees. However, new staff can bring benefits such as introduction of new ideas to the business, or more efficient workers. Absenteeism is another measurement to the companys workforce, as it tells managers how much their staff go on break from work. This can be a substantial problem for the business, because production output will suffer if employees are absent, projects will run into delays, and the quality of products affected due to the lack of staff. There are many other costs associated with absent staff, such as sick pay, and temporary staff pay, which is often expensive. Absenteeism also cause de-motivation in the business, as other employees will have to take the work load of the absent employees. To lower the level of absenteeism, the business can issue fines to absent staff, improve the safety of the work environment so staff would want to be at work, and improve their motivational methods. British Sugar uses a range of performance indicators to evaluate and improve their performance. SMART targets are a set of criteria that are based on the specific words: specific, measurable, attainable, relevant and time-specific. These criteria are applied in the process of making goals and objectives, to maximise the business chances of obtaining them. Punctuality is the characteristic of being able to complete a required task or fulfill an obligation before or at a previously designated time. Attendance is the frequency with which a person is present. An appraisal system, or performance management, is a proactive and continuous process of communicating and clarifying role responsibilities, performance expectations and priorities in order to ensure mutual understanding between managers and employees. It is very useful as it is both a motivational strategy and a review system where mangers can assess their employees. The appraisal system would fulfill the employees social and recognition needs according Maslow theories, motivating to work harder to achieve more and be more recognised. The system is not without flaws, however. The appraisal system can be very costly, requiring a lot of administrative work, and is time-consuming. It is also exposed to favouritism. Managers can tend to trust and praise some employees more than others, causing distrust discontentment among team members.

Watership Down Quotes

'Watership Down' Quotes Watership Down is a novel by Richard Adams. Its popular on many high school reading lists. The work is an allegory: a fantasy about a group of rabbits in search of a warren. Here are a few quotes from Watership Down. The Threarah doesnt like anything he hasnt thought of for himself.- Richard Adams, Watership Down Note: This quote refers to the chief rabbit, and it tells us a little bit about the leadership in the rabbit community. This is the type of example that the younger generations have to followthe leaders they have to look up to. Its very self-centered  and does not consider what is best for the community. El-ahrairah, your people cannot rule the world, for I will not have it so. All the world will be your enemy, Prince with a Thousand Enemies, and whenever they catch you, they will kill you. But first they must catch you, digger, listener, runner, prince with the swift warning. Be cunning and full of tricks and your people shall never be destroyed.- Richard Adams, Watership Down Note: This quote reminds us of many of the trickster-like tales and legends. In Watership Down, the quote is derived from Dandelions myth. As in many of the other mythic tales were familiar with in literary history, gifts are given: intelligence (cunning), speed (runner), and strength (digger). Rabbits need dignity and above all the will to accept their fate.- Richard Adams, Watership DownTheyd altered what rabbits do naturally because they thought they could do better.- Richard Adams, Watership Down Note: Animals in the wild will act (and react) in certain ways that seem natural, but are also part of learned responses. When they learn that those behaviors are no longer required, some animals begin to act in unnatural ways. They could have comfortable burrows (for example), but buck rabbits wont (cant) dig. Their (natural) way of life has been changed. I think we ought to do all we can to make these creatures friendly. It might turn out to be well worth the trouble.- Richard Adams, Watership DownThe truth is, youre just a silly show-off.- Richard Adams, Watership DownWe all have to meet our match sometime or other.- Richard Adams, Watership DownI have learned that with creatures one loves, suffering is not the only thing for which one may pity them. A rabbit who does not know when a gift has made him safe is poorer than a slug, even though he may think otherwise himself.- Richard Adams, Watership DownIf a rabbit gave advice and the advice wasnt accepted, he immediately forgot it, and so did everyone else.- Richard Adams, Watership DownIf my authority goes, where will yours be in half a day.- Richard Adams, Watership Down

How can we define authorship in TV Assignment Example | Topics and Well Written Essays - 500 words

How can we define authorship in TV - Assignment Example Given this argument, it follows that the identification of the technical competence of the director would enable critic and viewers alike to determine the quality and artistic value of the TV program. Auteurism however has been criticized in its application to film and TV show making because the creation of a film or show involves a lot of people in its production process that it would be difficult to say that a certain individual was solely responsible of the authorship or creation of the film (Moran 1999). Moreso, in a Hollywood setting where a multitude of people had to work and collaborate together to create a film. We can cite for example the film The Big Sleep (1946) which was a product of collaboration with different film makers. It involved novelist Raymond Chandler who wrote the novel which was the basis of the film, Howard Hawks, screenwriters William Faulkner, Leigh Brackett and actors Humphrey Bogart and Lauren Bacall (Lev 1988) all were distinguished artists in their own right. It is also important to note that the film made a last minute revision in January of 1946 invites discussion about authorship because it clarifies when and who decides for the change of the fi lm indicating ownership of the film (Lev 1988). This is an important notion of auteurism because it highlights the complicity in according authorship in a film as argued by the critics of auteurism. In contemporary setting in creating a TV program various creative people are involved to complete the production. It involves Director,  Producer,  Creator,  Executive producer,  Assistant producer,  Researcher,  Star,  Writer, all of which have creative inputs to complete the production of a TV program. Such, if we are to determine authorship in the strict meaning of the word, it would be difficult to assign it to a single individual because no individual can complete a TV program by himself.   We can however infer to the

A Worn Path Essay Example | Topics and Well Written Essays - 500 words - 1

A Worn Path - Essay Example The setting of the story as written by the author is based on the Natchez Trace as well as the town of Natchez. Phoenix who is the protagonist in the video is an elderly Black American woman who subsequently goes on a heroic quest to rightly procure medicine for her beloved ill grandson. Throughout the story, the author uses different literary devices in order to make the story interesting. The Video also delivers the unforgettable character in the Black American woman, who does not even know when she was born. From the video, critics are well evident throughout the storyline. The various literary devices that are highly used in the video include allusion, metaphor, imagery, Simile and alteration. Allusion is a literary device that is used in the main character of the story, Phoenix. The name of phoenix is the similar to the mythical bird that subsequently raises the air and eventually bursts into flames. This bird is consumed by fire and when it gets burnt, a new phoenix spring emerges from the ashes. The old black woman is also old to walk in the difficult on her way to Natchez to get the medicine for her grandson. However, her age does not matter as the only thing that she believes in is that she has to have his medicine or die while trying. Metaphor is another literary device that is used in the video. From the video, it is quoted that the black woman walked slowly, a little side to side with a well-balanced heaviness, and with the lightness of the pendulum in the grandfather clock. Through such use of literary device, the author makes the character as well as the story to come into life. The Black old woman ambles in the cold, while she walks on the path multiple times for the sake of her grandson. However, due to his old age, her footing is quite unsure and she is seen to waver from side to side while walking. Imagery is also evident in the video. Throughout the

Questions on strategic management Research Paper

Questions on strategic management - Research Paper Example In addition, understanding the business environment through research and other relevant actions ensures identification of strategic factors (Cherunilam 55). This move only makes sure that the international firms will be able to learn more about the business environment. And once they do, it would be easy for them to embrace some changes having the bottom line within the formulation of actual strategic actions. Knowing the business environment is important because this is one appropriate move in order to know the necessary actions the international firms need to initiate. Multiculturalism for instance is a core value that needed to be integrated especially among corporations having business activities in the international setting. 2. Compare and contrast trend extrapolation with the writing of scenarios as techniques. (Support your answer with an example). Trend extrapolation is quantitative in nature. Information can either be represented in a quantitative format or with numerical va lue. Graphs and other quantitative representations can be used for this purpose (Cornish 86). The writing of scenarios on the other hand is qualitative in its form, as this could also turn out historical. Although both trend extrapolation and writing scenarios are techniques that could turn out historical in nature, for they involve the need to look into past events or data. However, they vary in their actual presentation for it would be easy to interpret data transformed into information presented in graphical forms. For example, understanding the past trend of sales generated by a certain product offering could be both implemented through trend extrapolation and writing scenarios techniques. Both are actually capable of presenting the necessary and relevant information. However, for the convenience of using and interpreting information, there is a good way to find it more possible with trend extrapolation. On the other hand, trend extrapolation may be complex enough as this techni que unlike the writing scenarios, requires mathematical implementation. Trend extrapolation may be complex, for it would also require the right number of data in order for the obtained information to be statistically relevant. 3. How might a firm’s management decide whether it should continue to invest in familiar technology or in new but untested technology? What factors might encourage or discourage such a shift? (Support your answer with an example). There are many factors associated with making this decision, but one of them include efficiency. Firms are looking forward to efficient output in order to maximize opportunity and to generate revenue and eventually profit. The next consideration is productivity. Productive output today requires the use of technology, in order to hit the required volume of production necessary to help the entire business operation to continue operate. On the other hand, there is also a need to achieve competitive advantage so there is also a ne ed to consider whether to embrace new but untested technology or remain with the most familiar one. There are familiar technologies nowadays that could continue to provide firms with the achievement of the above mentioned factors at a higher remarkable cost saving. So for this reason, a company would be able to choose

CHAPTER 2 LITERATURE SURVEY Contents: World Wide Survey of Renewable Energy Demand Supply Gap in Pakistan Depletion in Oil and Gas Energy Sources in Pakistan Wind Energy Solar Energy 2.1 World Wide Survey of Renewable Energy Renewable energy has an essential contribution in world energy generation. So many projects are under consideration regarding to renewable energy. 2.1.1 Global Status Report This report describes the market condition, investment and targets as well as policies. The report doesnt describe analysis or conclusions, though it reveals some extra ordinary facts regarding the renewable energy . By the end of 2005 only 45 countries were included in the achievement of renewable energy targets which are increased up to 76 in 2009. According to this report last year was the best era for renewable energy. Capacity in developing countries grew to 119GW, or 43% of the total. Including Pakistan and magnolia less or more than 8-0 countries has started plantation of wind power plants at commercial measures[7]. Some achievements of the year 2008 are: In just 1 year the capacity of solar photovoltaic plants tripled to 3 GW from 200 KW. Wind power by 29% and solar hot water increased by 15%. Grid connected photovoltaic systems increased up to 13GW, wind energy grew up to 250%, 121GW and total power generation capacity from renewable energy boost up to 75%. Spain becomes the super power in the field of grid connected PV systems with inclusion of 2.6GW. Germany also takes some handy steps and added 1,5GW in their system. Some other developed countries also provide large contributions like USA(3ooMW), Italy ( 300MW) , South Korea ( 270MW) and Japan (240MW) respectively . in total 16GW is the generation of solar including off-grid by 2009 worldwide. Table2.1 Energy Added and Exists in 2009-2010 2.2 Demand Supply gap in Pakistan If we give a look at demand supply graph then we will come to know that the difference between demand and supply is becoming wider and wider by the passage of time .the scenario in 3rd world countries is totally discriminated e.g. Pakistan. Needs are increasing exponentially but we are desperately lacking in finding out a good solution. if we have an eye view we may find 3 reasons of demand supply gap. Increase in prices of oil and gas , increase in population and increase in cost of energy . 2.2.1 Energy Demand With the increase in population energy requirements are also increasing. All the industry and the production of our daily need in dependent upon electricity . 2.2.2 Energy Supply Current eras total production of energy does not meet the current requirement of energy , though the end results are critical in the sense of increase in demand supply gap . Serious steps are needed to be 2.2.3 Energy cost If we have eye view on last few decades we will come to see the highlighted reduction in the reserves of oil and natural gas, which causes the increase in the cost of per unit production of electricity. This is also the reason of widening the demand supply gap. 2.2.4 Sustainability level The systems which are to be used for the generation of electricity must be stable, but unfortunately we have not surety of sustainability level of present system and the graph is gradually decreasing according to our present and future demands . This decrease in sustainability may overcome by using alternative techniques. 2.3 Depletion in oil and gas A large amount of electricity is being produced by fossil fuels and the present value of electricity generated by fossil fuels is increasing. According to the European energy commission and International energy the present reservoirs of oil and gas are not sufficient enough to meet the future requirements. so as the result after 10-12 years we have the depletion in the percentage of Oil using for the generation of electricity as shown in fig 2.2. As from the above it is obvious that from 1930 to one word till 2010 there is continuous growth in both oil and gas reserves but after 2010 there is deep declined. If the above graph follows the same pattern there is near future we will be totally dependent upon alternates of energy generation. 2.4 ENERGY SOURCES IN PAKISTAN The primary energy supplies today are not enough to meet even the present demand. More, a very large part of rural area does not have the electricity facilities because they are too expensive to be connected to the national grid. So, Pakistan like other developing countries in the region is facing a severe challenge in energy deficit. The development of renewable energy sources can play an important role in meeting such challenge. If we see around yourself Pakistan best suits for Solar (PV, thermal), water, wind and Wastes. These are the best renewable sources and Pakistan doesnt lack these. Pakistan can b benefited from these as substitute energy in areas where these renewable sources exist. Renewable energy Fossil fuels Nuclear power 2.4.1 Renewable energy It is energy which is produced by natural sources such as wind rain solar and geothermal heat. 2.4.1.1 Types of renewable Energy Wind Biomass Solar Wave and tidal Geothermal These all sources are best placed in Pakistan and we are not lacking in any at all , thus we can produce great amount of energy using these renewable sources , Capturing renewable energy by animals , plants and humans does not permanently deplete the resource. Fossil fuels are renewable but on a very long time-scale, are exploited at rates that may deplete these resources in the near future. 2.4.2 Fossil Fuels It includes natural gas, oil and coal . fossil fuels are lacking in Pakistan as well the world therefore renewable sources are needed to meet th essential needs 2.5 Wind Energy Wind energy is one of the best of renewable sources and probably suits Pakistan atmosphere at peak. As our project is related to wind energy as well. In Pakistan wind energy projects are working under the Pakistan Meteorological Dept with the financial collaboration of Ministry of Science and Technology which are accomplishing many such projects in Pakistan. About 3% of the total Pakistans land area is termed as good to excellent for utility scale production of electricity. Fig2.3. shows the variations of wind speeds in different areas of Pakistan Average wind speed in Lahore is 3m/s as shown in Fig.2.4 . Therefore for the prototype smart Grid system, average wind speed must exceeds the theoretical values as given in[10]. 2.6 Solar energy Its one of the types of renewable energies, as in our project we are working on solar energy, in photovoltaic system solar cells covert sun radiation to DC electricity. The provinces of Sindh , Punjab and Baluchistan and the Thar desert are specially suited for the utilization of solar energy. The solar statistics in Pakistan is highly favourable for energy generation. According to Fig2.5. the South western province offers perfect condition for utilization of solar energy. Since Pakistan locates near the equator so it has relatively high UV index as compared to other regions of the World. The solar characteristics graph in the Lahore region is shown in Fig. 2.6. Lahore city also offers suitable condition for harnessing solar energy The average sunlight hours lies between 7 to 8 hours per day which is approximately 2700 hours per annually. Graph in Fig. 3 shows the UV index of Lahore during a day time in the month of April. Usually the radiation intensity has its maximum value at noon .And value of solar radiation reaches its maximum value during the mid of summers. Chapter No 3 PHOTOVOLTAIC SYSTEM Contents: Introduction to solar panels History of PV system Photovoltaic Cell Architecture Implementation of PV system Battery 3.1 Introduction: Solar cell or photovoltaic cell is the device use to convert sunlight into electricity. It works on the basic principle of photovoltaic effect. 3.1.1 Photovoltaic effect When the photons of light falls on the semiconductor material. The photons try to knockout the electrons from the conduction bands. As the energy gap between valence and conduction band increases and when a sufficient amount of energy is projected by the light photons .the electrons knocked out from their respective atom and started to move freely. These free electrons moves towards n-side and holes created due to the deficiency of electrons in this region moves towards p-side to recombine themselves .This difference of potential allows the flow of current. The PV cell absorbs incoming light photons in p-type. This p-type layer should be synchronized in such a way that it can absorb as many as photons possible and set free as many as electrons possible, to make a radiant flow of current. In order to make and efficient flow solar cell , the surface of the cell should be kept rough to maximize the absorption of photons while reflection should be minimized in this way maximum conduction can be achieved 3.2 History The photovoltaic cell was developed in 1954 at Bell Laboratories. The first highly efficient solar cell was developed by Daryl Chapin, Calvin Souther Fuller and Gerald Pearson in year 1954 using a diffused silicon p-n junction. Firstly, cells were developed for toys and other minor uses, as the cost of their production was very high. Design of solar cells is improved day by day to utilize it for more applications. The applications for that solar panels are used are different and there are three levels of generation 3.2.1 First Generation: First generation cells are single junction devices and they have large area also having high quality with reduction in production cost 3.2.2 Second Generation: These materials are developed to address energy requirements and production cost. They reduce high temperature processing as vapour deposition, electroplating and Ultrasonic nozzles. 3.2.3 Third Generation: The aimof these technologies is to improve poor electrical performance of second generation technologies with low production cost. 3.3 Photovoltaic cell architecture A PV module consists of a silicon cell .These cell are connected in series or parallel manner in order to produce desired voltage and current .Inside a PV cell a circuit is present that is sealed from the envoi metal protective lamination .A PV panel consists of one or more modules joined together. Finally these panels are combined to make a single PV array which is a complete electricity producing unit. The performance of a PV array or its modules is rated by its maximum throughput power under S.T.C (Standard Test Condition).STC is defined as when a PV modulecell is operated under 25  °C (77F), with an incident solar irradiation of 1000 W/m2 with the spectral distribution of 1.5 air mass. These are the perfect condition for a PV module to operate in , but in actual the performance of a PV module is almost 80 to 90 percent of its STC rating. The operating lifetime of a PV module is between 20 to 30 years .Most of the manufactures offers warranty of 20 or more years of its DC output power to a sustainable amount .PV modules are also lice censed under (UL) qualification test for its reliability checks. 3.3.1 Types of Solar Cell Now a days there are various types of cell materials are developed. Multi junction PV cells are made in order to increase the cell efficiency while decreasing its volume and weight. But they are far more expensive then an ordinary silicon cells. The maximum efficiency of a PV cell is achieved almost to 30 percent by doping different intrinsic material together .Example of the exotic materials are Gallium arsenide and Indium serenade etc. However silicon cells are the most common and widely used PV cells. There are three major types of Silicon cell: Amorphous silicon solar Cell or Thin Film Cell Mono-crystalline Wafers Poly crystalline Cell Amorphous Silicon Solar Cell Amorphous technology is often seen in small devices, such as those in garden lamps or calculators, although amorphous panels are also increasingly used in other larger applications. They are formed by depositing a thin film of silicon onto a sheet of different material such as steel. The panel formed as one piece and each cell is not as visible as in other types. Efficiency of an amorphous solar cell is between 6 and 8%. The Lifetime of an amorphous cell is however shorter than that of crystalline cell. Amorphous cells have current density of about 15 mA/cm2,and the voltage of the cell without any connected load is 0.8 V, which is more as compared to crystalline cells. The efficiency of amorphous solar panels is low as those made from individual solar cells, although improvement has been made over recent years to a point where they can be use as a practical alternative to panels made with crystalline cells. Crystalline silicon solar cell The maximum efficiency of silicon solar cell is around 23 %, by adding some other semi-conductor materials it can increase up to 30 %, it depends on wavelength and semiconductor material being used. Crystalline solar cells are made up of wafers like stuff, which has about 0.3 mm thick and diameter of 10 to 15 cm. They can generate approximately 35 mA of current per cm2 of area at voltage of about 550 mV at full illumination. Crystalline solar cells can be wired in series or parallel to produce a solar panel. As each cell produces a voltage of between 0.5 and 0.6 Volts, 36 cells equipped in series are needed to produce an open-circuit voltage of about 20 Volts. This is enough to charge a 12 Volt battery under certain conditions. Although the efficiency of mono-crystalline cells is slightly higher as compared to that of a polycrystalline cells, but there are some practical difference in their performance. Crystalline cells have longer lifetime than that of amorphous solar cells. In our project we have used crystalline silicon cell because they are more efficient yet lesser in volume as compared to other types of solar cell, easily available in market and it is more economical. Polycrystalline Cell Polycrystalline silicon, also called poly silicon , consists of small silicon crystals of Polycrystalline cells which can be recognized by a visible grain, a â€Å"metal flake effect†. Semiconductor grade (solar grade) polycrystalline silicon then form to single crystal silicon, that is randomly associated crystallites of silicon in polycrystalline silicon are converted to a large single crystal[11]. Single crystal silicon is used in manufacture most of Si-based microelectronic devices. Polycrystalline silicon can be available up to 99.9999% pure. 3.4 Implementation of PV system: 3.4.1 Types of PV system There are three types of PV system being implemented around the world depending upon its function and integration with other energy resources. Standalone PV system Grid Connected PV system Hybrid Systems Stand alone PV system This type of system is usually present in our wrist watches, calculators and in space crafts also. These are dependent totally on its self generated power through solar panels and are directly used by DC loads or AC loads through inverter. In some system battery bank is also available to store the unused power to facilitate loads during night or under low light conditions. Further more a charge controller is also required in order to avoid battery from over charging and deep discharging. An inverter is also employed to provide power to AC loads. Grid Connected PV system In grid connected type the PV module has also backed up with WAPDA line or Grid connection. In this way if load is not getting enough power from the PV module or its battery, it will switch to the WAPDA line. This type of system is most commonly used around the World. Its applications are found mostly in small industries and homes. Hybrid System In this type the PV system is also integrated with two or more type of energy resources which may or may not be renewable resources .For example a wind turbine, steam engine or a small hydro plant etc. Other energy sources can also be integrated depending upon climate, geographical location of the place and several other perspectives. These systems are more appropriate for remote applications such as military installation, communication stations and rural villages. 3.4.2 Design Methodology Our project is based on a Hybrid System Consisting of a PV module and a windmill as two renewable energy resources, we have chosen these sources keeping in mind the climate and terrain of Lahore. 3.4.2.1 Components of Photovoltaic system: Solar cell Panel Inverter Charge Controller Batteries Integrator The major component of our system is the integrator .The function of this device is to integrate powers from both energy sources in a way that during operating time of the sources loads will directly get power from these sources and at night or the time when these sources are not operating loads are facilitated through battery banks. A controller is placed in the integrator circuit that is continuously monitoring the voltage level being provided by the sources. If the load can operate single handed by either of the sources the rely will build its connection from load with that source while the energy generated by the second source is being stored in the batteries .If both sources are required to derive a certain load rely opens up its connection of both sources with the load. When both sources are not providing a sufficient amount of power to the loads the controller will check whether batteries could provide sufficient amount of voltage so, it will start delivering power to load from the battery bank otherwise an LED blinks indicating that system cannot provide sufficient amount of power and will shutdown eventually. 3.4.2.2 Solar Panel Characteristics Table 3.1.

Table 3.2. Solar Panel Throughput 3.4.2.4 Factors Affecting Output Power STC(Standard Test Condition) The electricity produce by solar cell is in DC, the DC output of solar panel is Tested under the STC that is Cell Temperature= 25 °C Solar Radiation Intensity= 1000 W/m2.. Air Mass= 1.5 These are the standard test condition at which Solar cell gives its Maximum Efficiency, in other conditions there is almost 10 to 15 percent of decrease in the efficiency of cell with respect to its STC rating. Temperature Output power of the solar cell is inversely proportion to the increase in temperature of the cell. For a crystalline module , a typical temperature reduction factor proposed by CEC is 89 percent which means †95 watts† module will typically provide 85 Watts (95watts*0.89=85watts) under sunlight conditions during summer seasons. Mismatch and wiring Losses The performance of the system can be affected due to mismatch of module connections. The loss in power also depends upon the increase in length of wire between source and load. As the distance between source and load increases losses also increases. Therefore the distance should be kept minimal to get maximum power throughput.

By 2020 energy demand will be doubled from the present demand [1]. Smart grid is the result of such efforts which are performed to make availability of electricity more reliable, economical and user friendly with the concept of decentralized network due to two way communication of electricity through network[2]. The Architectural model of a 21st century power system that interconnects everyone to affordable, abundant, clean, reliable, and efficient electricity anytime, anywhere. The purpose of Smart Grid is also to integrate several renewable resources with our national Grid and enhances the efficiency; reliability and thus providing a hassle free Transmission of electric power. It also contributes to reduce carbon emissions and providing a pollution free environment. 1.2 Back Ground 1.2.1 The European Development in the Area of Smart Grid In the next three decades European member state will expend about 750 billion in power infrastructure. This amount will expend on generation and networks. The European Technology plate form was developed in 2005 to solve the problems of Network Owners, operators and users[3]. 1.2.2 Smart Grid Development in USA In USA the Smart grid developments initiated during first Bush Administration[4]. In 2002 a DOE study describes the hundred of million of Dollar spent In US power systems on transmission practices and results a proposal of construction of transformed national electricity grid upto2030 providing the best and secure transmission of electricity[5]. 1.2.3 Smart Grid Development in Australia Under the Energy Transformed Flagship the Intelligent Grid Program was launched on 19 Aug, 2008. This Program researched in the fields of Control methodologies and economic modeling for distributed generation, Social impact of Intelligent grid, New housing developments and micro grids[6]. 1.3 Design Description 1.3.1 Features of Smart Grid The most important features of Smart Grid Technology are: Integration of Renewable Sources Battery Storage option Provide electric power to both AC and DC loads Advance Monitoring 1.3.2 Proposed Methodology Above figure shows prototype modeling of smart grid system at micro level along with the integration of several renewable energy resources such as small wind plant and solar panels. The charge controllers are special devices used for the purpose to control the abrupt change in voltage and stop the reverse flow of current towards PV or wind turbine systems, and also control the charging and discharging of batteries. An integrator is also one of the most important components of our project. The function of this device to integrate powers from both energy sources in a way that during operating time of the sources loads will directly get power from these sources and at night or the time when these sources are not operating loads are facilitated through battery banks. 1.4 Advantages of Smart Grid A.

CHAPTER 2 LITERATURE SURVEY Contents: World Wide Survey of Renewable Energy Demand Supply Gap in Pakistan Depletion in Oil and Gas Energy Sources in Pakistan Wind Energy Solar Energy 2.1 World Wide Survey of Renewable Energy Renewable energy has an essential contribution in world energy generation. So many projects are under consideration regarding to renewable energy. 2.1.1 Global Status Report This report describes the market condition, investment and targets as well as policies. The report doesnt describe analysis or conclusions, though it reveals some extra ordinary facts regarding the renewable energy . By the end of 2005 only 45 countries were included in the achievement of renewable energy targets which are increased up to 76 in 2009. According to this report last year was the best era for renewable energy. Capacity in developing countries grew to 119GW, or 43% of the total. Including Pakistan and magnolia less or more than 8-0 countries has started plantation of wind power plants at commercial measures[7]. Some achievements of the year 2008 are: In just 1 year the capacity of solar photovoltaic plants tripled to 3 GW from 200 KW. Wind power by 29% and solar hot water increased by 15%. Grid connected photovoltaic systems increased up to 13GW, wind energy grew up to 250%, 121GW and total power generation capacity from renewable energy boost up to 75%. Spain becomes the super power in the field of grid connected PV systems with inclusion of 2.6GW. Germany also takes some handy steps and added 1,5GW in their system. Some other developed countries also provide large contributions like USA(3ooMW), Italy ( 300MW) , South Korea ( 270MW) and Japan (240MW) respectively . in total 16GW is the generation of solar including off-grid by 2009 worldwide. Table2.1 Energy Added and Exists in 2009-2010 2.2 Demand Supply gap in Pakistan If we give a look at demand supply graph then we will come to know that the difference between demand and supply is becoming wider and wider by the passage of time .the scenario in 3rd world countries is totally discriminated e.g. Pakistan. Needs are increasing exponentially but we are desperately lacking in finding out a good solution. if we have an eye view we may find 3 reasons of demand supply gap. Increase in prices of oil and gas , increase in population and increase in cost of energy . 2.2.1 Energy Demand With the increase in population energy requirements are also increasing. All the industry and the production of our daily need in dependent upon electricity . 2.2.2 Energy Supply Current eras total production of energy does not meet the current requirement of energy , though the end results are critical in the sense of increase in demand supply gap . Serious steps are needed to be 2.2.3 Energy cost If we have eye view on last few decades we will come to see the highlighted reduction in the reserves of oil and natural gas, which causes the increase in the cost of per unit production of electricity. This is also the reason of widening the demand supply gap. 2.2.4 Sustainability level The systems which are to be used for the generation of electricity must be stable, but unfortunately we have not surety of sustainability level of present system and the graph is gradually decreasing according to our present and future demands . This decrease in sustainability may overcome by using alternative techniques. 2.3 Depletion in oil and gas A large amount of electricity is being produced by fossil fuels and the present value of electricity generated by fossil fuels is increasing. According to the European energy commission and International energy the present reservoirs of oil and gas are not sufficient enough to meet the future requirements. so as the result after 10-12 years we have the depletion in the percentage of Oil using for the generation of electricity as shown in fig 2.2. As from the above it is obvious that from 1930 to one word till 2010 there is continuous growth in both oil and gas reserves but after 2010 there is deep declined. If the above graph follows the same pattern there is near future we will be totally dependent upon alternates of energy generation. 2.4 ENERGY SOURCES IN PAKISTAN The primary energy supplies today are not enough to meet even the present demand. More, a very large part of rural area does not have the electricity facilities because they are too expensive to be connected to the national grid. So, Pakistan like other developing countries in the region is facing a severe challenge in energy deficit. The development of renewable energy sources can play an important role in meeting such challenge. If we see around yourself Pakistan best suits for Solar (PV, thermal), water, wind and Wastes. These are the best renewable sources and Pakistan doesnt lack these. Pakistan can b benefited from these as substitute energy in areas where these renewable sources exist. Renewable energy Fossil fuels Nuclear power 2.4.1 Renewable energy It is energy which is produced by natural sources such as wind rain solar and geothermal heat. 2.4.1.1 Types of renewable Energy Wind Biomass Solar Wave and tidal Geothermal These all sources are best placed in Pakistan and we are not lacking in any at all , thus we can produce great amount of energy using these renewable sources , Capturing renewable energy by animals , plants and humans does not permanently deplete the resource. Fossil fuels are renewable but on a very long time-scale, are exploited at rates that may deplete these resources in the near future. 2.4.2 Fossil Fuels It includes natural gas, oil and coal . fossil fuels are lacking in Pakistan as well the world therefore renewable sources are needed to meet th essential needs 2.5 Wind Energy Wind energy is one of the best of renewable sources and probably suits Pakistan atmosphere at peak. As our project is related to wind energy as well. In Pakistan wind energy projects are working under the Pakistan Meteorological Dept with the financial collaboration of Ministry of Science and Technology which are accomplishing many such projects in Pakistan. About 3% of the total Pakistans land area is termed as good to excellent for utility scale production of electricity. Fig2.3. shows the variations of wind speeds in different areas of Pakistan Average wind speed in Lahore is 3m/s as shown in Fig.2.4 . Therefore for the prototype smart Grid system, average wind speed must exceeds the theoretical values as given in[10]. 2.6 Solar energy Its one of the types of renewable energies, as in our project we are working on solar energy, in photovoltaic system solar cells covert sun radiation to DC electricity. The provinces of Sindh , Punjab and Baluchistan and the Thar desert are specially suited for the utilization of solar energy. The solar statistics in Pakistan is highly favourable for energy generation. According to Fig2.5. the South western province offers perfect condition for utilization of solar energy. Since Pakistan locates near the equator so it has relatively high UV index as compared to other regions of the World. The solar characteristics graph in the Lahore region is shown in Fig. 2.6. Lahore city also offers suitable condition for harnessing solar energy The average sunlight hours lies between 7 to 8 hours per day which is approximately 2700 hours per annually. Graph in Fig. 3 shows the UV index of Lahore during a day time in the month of April. Usually the radiation intensity has its maximum value at noon .And value of solar radiation reaches its maximum value during the mid of summers. Chapter No 3 PHOTOVOLTAIC SYSTEM Contents: Introduction to solar panels History of PV system Photovoltaic Cell Architecture Implementation of PV system Battery 3.1 Introduction: Solar cell or photovoltaic cell is the device use to convert sunlight into electricity. It works on the basic principle of photovoltaic effect. 3.1.1 Photovoltaic effect When the photons of light falls on the semiconductor material. The photons try to knockout the electrons from the conduction bands. As the energy gap between valence and conduction band increases and when a sufficient amount of energy is projected by the light photons .the electrons knocked out from their respective atom and started to move freely. These free electrons moves towards n-side and holes created due to the deficiency of electrons in this region moves towards p-side to recombine themselves .This difference of potential allows the flow of current. The PV cell absorbs incoming light photons in p-type. This p-type layer should be synchronized in such a way that it can absorb as many as photons possible and set free as many as electrons possible, to make a radiant flow of current. In order to make and efficient flow solar cell , the surface of the cell should be kept rough to maximize the absorption of photons while reflection should be minimized in this way maximum conduction can be achieved 3.2 History The photovoltaic cell was developed in 1954 at Bell Laboratories. The first highly efficient solar cell was developed by Daryl Chapin, Calvin Souther Fuller and Gerald Pearson in year 1954 using a diffused silicon p-n junction. Firstly, cells were developed for toys and other minor uses, as the cost of their production was very high. Design of solar cells is improved day by day to utilize it for more applications. The applications for that solar panels are used are different and there are three levels of generation 3.2.1 First Generation: First generation cells are single junction devices and they have large area also having high quality with reduction in production cost 3.2.2 Second Generation: These materials are developed to address energy requirements and production cost. They reduce high temperature processing as vapour deposition, electroplating and Ultrasonic nozzles. 3.2.3 Third Generation: The aimof these technologies is to improve poor electrical performance of second generation technologies with low production cost. 3.3 Photovoltaic cell architecture A PV module consists of a silicon cell .These cell are connected in series or parallel manner in order to produce desired voltage and current .Inside a PV cell a circuit is present that is sealed from the envoi metal protective lamination .A PV panel consists of one or more modules joined together. Finally these panels are combined to make a single PV array which is a complete electricity producing unit. The performance of a PV array or its modules is rated by its maximum throughput power under S.T.C (Standard Test Condition).STC is defined as when a PV modulecell is operated under 25  °C (77F), with an incident solar irradiation of 1000 W/m2 with the spectral distribution of 1.5 air mass. These are the perfect condition for a PV module to operate in , but in actual the performance of a PV module is almost 80 to 90 percent of its STC rating. The operating lifetime of a PV module is between 20 to 30 years .Most of the manufactures offers warranty of 20 or more years of its DC output power to a sustainable amount .PV modules are also lice censed under (UL) qualification test for its reliability checks. 3.3.1 Types of Solar Cell Now a days there are various types of cell materials are developed. Multi junction PV cells are made in order to increase the cell efficiency while decreasing its volume and weight. But they are far more expensive then an ordinary silicon cells. The maximum efficiency of a PV cell is achieved almost to 30 percent by doping different intrinsic material together .Example of the exotic materials are Gallium arsenide and Indium serenade etc. However silicon cells are the most common and widely used PV cells. There are three major types of Silicon cell: Amorphous silicon solar Cell or Thin Film Cell Mono-crystalline Wafers Poly crystalline Cell Amorphous Silicon Solar Cell Amorphous technology is often seen in small devices, such as those in garden lamps or calculators, although amorphous panels are also increasingly used in other larger applications. They are formed by depositing a thin film of silicon onto a sheet of different material such as steel. The panel formed as one piece and each cell is not as visible as in other types. Efficiency of an amorphous solar cell is between 6 and 8%. The Lifetime of an amorphous cell is however shorter than that of crystalline cell. Amorphous cells have current density of about 15 mA/cm2,and the voltage of the cell without any connected load is 0.8 V, which is more as compared to crystalline cells. The efficiency of amorphous solar panels is low as those made from individual solar cells, although improvement has been made over recent years to a point where they can be use as a practical alternative to panels made with crystalline cells. Crystalline silicon solar cell The maximum efficiency of silicon solar cell is around 23 %, by adding some other semi-conductor materials it can increase up to 30 %, it depends on wavelength and semiconductor material being used. Crystalline solar cells are made up of wafers like stuff, which has about 0.3 mm thick and diameter of 10 to 15 cm. They can generate approximately 35 mA of current per cm2 of area at voltage of about 550 mV at full illumination. Crystalline solar cells can be wired in series or parallel to produce a solar panel. As each cell produces a voltage of between 0.5 and 0.6 Volts, 36 cells equipped in series are needed to produce an open-circuit voltage of about 20 Volts. This is enough to charge a 12 Volt battery under certain conditions. Although the efficiency of mono-crystalline cells is slightly higher as compared to that of a polycrystalline cells, but there are some practical difference in their performance. Crystalline cells have longer lifetime than that of amorphous solar cells. In our project we have used crystalline silicon cell because they are more efficient yet lesser in volume as compared to other types of solar cell, easily available in market and it is more economical. Polycrystalline Cell Polycrystalline silicon, also called poly silicon , consists of small silicon crystals of Polycrystalline cells which can be recognized by a visible grain, a â€Å"metal flake effect†. Semiconductor grade (solar grade) polycrystalline silicon then form to single crystal silicon, that is randomly associated crystallites of silicon in polycrystalline silicon are converted to a large single crystal[11]. Single crystal silicon is used in manufacture most of Si-based microelectronic devices. Polycrystalline silicon can be available up to 99.9999% pure. 3.4 Implementation of PV system: 3.4.1 Types of PV system There are three types of PV system being implemented around the world depending upon its function and integration with other energy resources. Standalone PV system Grid Connected PV system Hybrid Systems Stand alone PV system This type of system is usually present in our wrist watches, calculators and in space crafts also. These are dependent totally on its self generated power through solar panels and are directly used by DC loads or AC loads through inverter. In some system battery bank is also available to store the unused power to facilitate loads during night or under low light conditions. Further more a charge controller is also required in order to avoid battery from over charging and deep discharging. An inverter is also employed to provide power to AC loads. Grid Connected PV system In grid connected type the PV module has also backed up with WAPDA line or Grid connection. In this way if load is not getting enough power from the PV module or its battery, it will switch to the WAPDA line. This type of system is most commonly used around the World. Its applications are found mostly in small industries and homes. Hybrid System In this type the PV system is also integrated with two or more type of energy resources which may or may not be renewable resources .For example a wind turbine, steam engine or a small hydro plant etc. Other energy sources can also be integrated depending upon climate, geographical location of the place and several other perspectives. These systems are more appropriate for remote applications such as military installation, communication stations and rural villages. 3.4.2 Design Methodology Our project is based on a Hybrid System Consisting of a PV module and a windmill as two renewable energy resources, we have chosen these sources keeping in mind the climate and terrain of Lahore. 3.4.2.1 Components of Photovoltaic system: Solar cell Panel Inverter Charge Controller Batteries Integrator The major component of our system is the integrator .The function of this device is to integrate powers from both energy sources in a way that during operating time of the sources loads will directly get power from these sources and at night or the time when these sources are not operating loads are facilitated through battery banks.
