The First Fundamental Theorem Of Welfare Economics

Introduction When studying market structure, the First Fundamental Theorem of Welfare Economics states that markets will distribute resources efficiently if the following conditions are met: the market is perfectly competitive, there are no externalities or public goods, markets are complete, and there is no asymmetric information (Gruber, 2013). If a healthcare market complied with these four pillars of the First Welfare Theorem, a healthcare provider’s choice of output would not affect the price of the service, ultimately leading to Pareto efficiency. As seen in Figure 1, the consumer demand curve would be horizontal, as average revenue, marginal revenue, and price would be the same, constant value. Figure 1: Perfect Competition†¦show more content†¦If the provider produces one extra unit of a good or service, the overall price decreases. The provider receives a lower price for infra-marginal goods, or the goods that would have been sold without reducing the price (Png, 2012). For example, if a healthcare provider chooses to increase production from 100 units to 200 units, the price must be reduced from $50 to $40. The provider will gain revenue (100 x $40= $4,000) from the additional units, but will lose ($50-$40) x 100= $1,000) the 100 infra marginal units that the provider could have sold at the higher price. So, average revenue for the provider will be $40, while marginal revenue will be $30. Thus, average revenue and price remain equal, while marginal revenue now falls below the price curve (Png, 2012). Figure 2: Marginal Revenue Curve vs. Average Revenue Curve in a Monopoly In order to determine price, the monopolist utilizes the inverse demand curve, also known as the average revenue curve. This curve reflects the price the provider would need to charge to produce demand at a particular level. Thus, the average revenue curve dictates what price the next unit can be sold at, while the marginal revenue curve reflects how much additional revenue is received for selling the next unit (Schwartz, 2010). As can be seen in Figure 3, since marginal revenue does not equal average revenue, the monopolist will set the quantity supplied where marginal revenue is equal to marginal cost. However, it willShow MoreRelatedArrow Impossibility Theorem1059 Words   |  5 Pagesâ€Å"The Arrow impossibility theorem and its implications for voting and elections† Arrow’s impossibility theorem represents a fascinating problem in the philosophy of economics, widely discussed for insinuating doubt on commonly accepted beliefs towards collective decision making procedures.

The Far-Reaching Effects of The Industrial Revolution Essay

During the period from the early 18th century to the mid 19th century people experienced many changes that had an impact on their lives such as technical advance, development of transport, trade, better organization of output or new financial structures. All these achievements happened spontaneously and were not planned. Economy was in process of rapid change and it gave many opportunities for people to gain wealth as well as social advancement.

No wonder that many workers disagreed and resisted either actively or passively. Those who were willing to adapt new system were forced to leave their domestic workshop because they would have had a little chance to compete against new factories. It was a change for entrepreneurs as well. They worked out the problems related to management, financing or accounting. If managers wanted to be successful they had to change the organization of work and control their employees. Before, work morale or fixed working hours were not common. Workers used to drink 3 days a week.Work was often inefficient, protracted and changes were necessary. Thanks to English pottery master Josiah Wedgewood, the most important innovations occurred during this era in the labour market. It was subdivision of tasks, training of new workers and work discipline. Let’s look at subdivision of work first. One worker no longer made the whole product by himself. Work was simplified to a single process and became a dull routine. Same mechanical process was incessantly repeated over and over again. Labour was prolonged and exhausting even though machines did mo st of the hard work. At the end, the product was made faster, quality of work was quite often better and it reduced the cost of production. Working conditions had changed as well.

Genre conventions in the films Control, Dead mans shoes and Casino Royale Essays

Genre conventions in the films Control, Dead mans shoes and Casino Royale Essays Genre conventions in the films Control, Dead mans shoes and Casino Royale Essay Genre conventions in the films Control, Dead mans shoes and Casino Royale Essay Essay Topic: Gun Control There are many different genres of film and each has its own set of generic conventions, films will follow these conventions to a certain degree. For example many mainstream Hollywood films will follow these conventions almost fully; films with a niche audience will often stray away from these generic conventions. A film that follows these conventions too strictly may be said to be boring and predictable however the audience may take pleasure from seeing conventions they know and take comfort from it. I am going to look at the films I am studying in terms of generic conventions and how they make use of them. The most conventional film is Casino Royale; it is a typical action film featuring almost everything the viewer would expect from an action film. One convention of an action film is that the character faces challenges and dangerous enemies. This is definitely true for this film with the protagonist facing many dangerous challenges such as gun fights and car chases. He also has dangerous human enemies such as Le Chiffre. : As this is a mainstream film with a high budget it will need to recoup this budget from sales and because of this the films producers will make sure the film follows generic conventions that they know the audience should enjoy instead of trying something new which may fail. Another generic convention of action films is beautiful women; this is also seen in Casino Royale with Vesper. Some scenes focus on her as a sexual object and this can be related to the male gaze theory. The main convention of an action film in my opinion is the following of the protagonist on his journey as he faces challenges; this hero will always succeed in conventional action films. This makes it very predictable for the audience who will often know for sure the hero is going to win and in a lot of cases the beautiful female (if there is one) will fall in love with him. However if the film breaks these conventions the viewer expects to see it will surprise them making the film more interesting and exciting. The least generic of these films in my opinion is Control, firstly because of its genre classification it is a biography, drama and music film. This is not a common form of film in comparison to the very popular action/adventure genre and this is why it is harder to say if it follows generic genre conventions. It is a lower budget independent film and I would say that it doesnt follow many typical mainstream conventions. One thing that makes this film less generic is that it is in black and white, this is to fit in with the time period the film is portraying and to make it more realistic. However this is something that a lot of mainstream films wouldnt use because their viewers may not appreciate it. A film on the same subject is Joy Division it gives the viewer an insight into the band and their lifestyle but in a different way. This shows how different films on the same subject can be as they follow conventions of different genres. Dead mans shoes is also a low budget film like control but in contrast it is fairly generic in its conventions. The main idea of the plot is of a man taking revenge on people by killing them. This basic idea can be found in many horror films and as the viewer may expect he does kill all of the people who had abused his brother. However the plot does have an unexpected twist with Richard getting the last victim to instead kill him. This is an example of how a typical plot can be changed to add excitement. A typical feature of this film is the violence and bloodshed featured, it is seen in most horror films and will be expected by the audience. For example in the scene when Richard drugs the victims he shoots one of them in the head, this is brutal and realistic violence. It could be compared to violence seen in Hollywood horror films such as saw, although these films are entirely different.

The American Dream Essay Example | Topics and Well Written Essays - 500 words - 4

The American Dream - Essay Example Thereby, if one accesses the viability of achieving the American Dream in the current times, it seems pragmatic to assert that the American Dream does not seem as much of an achievable option today. A range of social, political and economic facts corroborate to this belief. There is no doubt that the people in America do enjoy a better quality of life as compared to many other nations. It would also be safe to say that the poor in America today are better off as compared to the past. However, it is also a reality that economic class in America is something that is getting more rigid and difficult to transcend. The gap between the rich and the poor in America is further augmenting and the poor are not poor because they are less hard working or less willing to work. Class mobility has become an aspect of the American life that has really ossified (Kamolnick 114). The other things is that though the confidence and trust of the people in their nation’s innate capacity and fertility has traditionally been subservient to the imminent economic circumstances, still it is worth mentioning that the current economic meltdown has indeed shaken the people’s faith in the American dream. This is not because the people have lost faith in the values and beliefs underlying the American society. It is because people have largely come to believe that the rich and the powerful do have the power to get away with anything (Alpasian & Mitroff 143). They have the power to bring the national economy down on its knees, and the irony is that they will not be penalized for it but will rather be rescued by commensurate economic bailouts and privileges (Alpasian & Mitroff 157). One scarcely finds the trust and belief in many of the contemporary Americans that one traces in the works of Anne Bradstreet, a belief in the possibility for individual growth and t he maturity of personal talent, irrespective of the imminent constraints and shortcomings. It appears

Lowering Drinking Age from 21 to 18 Essay Example | Topics and Well Written Essays - 1250 words

Lowering Drinking Age from 21 to 18 - Essay Example This proposal essay takes a look at the legal age of drinking and why it should be rolled back to 18 years of age. It also pinpoints the essential changes that need to be made within the legislation as well as tackles problems in a head on fashion. There are chances which will crop up every now and then which will make the above-mentioned proposal sound illogical and insane yet the outcome is for the betterment of one and all, and especially the youth of present times. After all, they know what is good for them and how they can amend their lives in essence with the time and spirit of the present epoch. In the times much like today, people look at their lives in the form of an open canvas – waiting to throw paints on their personalities. Same is the case which holds true for drinking where they suggest and indeed I am of the view that it should be allowed at the age of 18 years because at this age, a person gets mature enough to distinguish the good and the bad for his own self . Tamura (1992) asks the question regarding lowering the drinking age since there have been amendments in the legislative processes of different countries from time to time. What this highlights is the fact that legislation under such domains is a significant impediment in the wake of lowering drinking prohibitions. The legal age is just a yardstick of measuring one’s age at the end of the day. It does not give any idea about a teenager’s mental and physical maturity. What it presents to one and all is a mere age dynamic.

Develop a leadership plan for addressing the issue identified in the Research Paper

Develop a leadership plan for addressing the issue identified in the case study - Research Paper Example The downtown areas of Monson largely populated by local government and municipal buildings suffered heavy losses of government property owing to the large scale destruction of government buildings and offices. Apart from the large scale destruction of residential and government properties the central and downtown areas of Monson also suffered from potential damage of several commercial properties. Many business offices operating in such regions had to close down or were bound to switch over to other areas by opening up newer branches. It is observed that the downtown region of Monson which was once largely populated with trees now was completely barren after being heavily struck by the tornado. Large scale destruction of residential properties in the downtown region were observed after the tornado strike ruined around 290 houses thereby claiming both properties and lives in a devastating fashion. Thus, it is found that the region of Massachusetts became struck by a tornado of deadly potential. In the light of the above case the paper tends to evaluate the leadership issues in regards to the conduct of emergency operations to save both life and property and thereby in citing an effective plan to help enhance the efficiency of the emergency plans. For Massachusetts the year of 2011 was quite a disaster as the state was struck with one of the largest tornadoes across around 18 community regions that claimed around 550 lives and made a huge chunk of the population homeless (Town of Monson, 2011, p.1; Earth Observatory, 2011). A large number of faults were observed in regards to leadership issues to render effective emergency services to the victims of such tornado devastated regions. Firstly, it was observed that there were huge communication gaps between the government authorities and the agencies that were working to promote emergency related services. There were also communication gaps where the people pertaining to the agency operations

Key performance Indicators (accounting and market) Coca-Cola Amatil Limited, being the largest company in the Asia Pacific in the soft drinks industry, has several key performance indicators which serve as the basis for its business decisions. According to ibisworld.com (2016), the Accounting Key Performance Indicators include: The Return on Revenue percentage Percentage Return on Shareholders Funds Percentage Return on Assets Percentage Profit Margin The Revenue per Employee The Net Profit after Tax (NPAT) per Employee The percentage Effective Tax Rate The Percentage Gearing The Interest Cover The Current Ratio The Dividends paid per Share The Marketing Key Performance Indicators are: The percentage change of Total Revenue Growth The percentage change in Sales Revenue Growth The Percentage change in Total Assets The percentage change in the Net Profit After Tax The percentage change in Earnings Before Interest, Tax, Depreciation and Amortization (EBITDA) The percentage change in Shareholders Funds Evaluation of the performance of Coca-Cola Amatil Limited Coca-Cola Amatil Limited is one of the major players in the Soft Drink Manufacturing Industry in Australia. The industrys retail market has been hit by changing customer preferences of soft drink which has led to a significant drop in revenue. However, the growth in popularity of energy and sports drinks has spearheaded the growth of the industry. According to IBISWorld.com (2016), the industry revenue has been projected to increase at an annual rate of 2.4% for the next five years through 2015-2016. In Australia, the company is ranked position 72 in the top 2000 companies. The primary source of income of the company is from the manufacture of beverage and tobacco in the Australia industry. According to ibisworld.com (2016), Coca-Cola Amatil Limited is reported to have generated total revenue of $5.253 billion in the year ending 2016. The company operates in two groups namely: Non-Alcoholic beverages, and Alcoholic, Food, and Services. Under the Non-Alcoholic Beverage segment, the company manufactures and distributes the Coca-Cola licensed products in five Asia Pacific countries which are Australia, New Zealand, Fiji, Papua New Guinea and Indonesia (IBISWorld.com, 2016). For the purpose of evaluation, the report will cover the various segments in which Coca-Cola Amatil Limited operates. Spirit Manufacturing in Australia In 2007, CCA started to venture into the alcoholic beverage market after signing a 10 year deal with Beam Global Spirits and Wines Inc and executing it as a joint venture with SABMiller (IBISWorld.com, 2016). As of 2016, the number of companies in the industry is 71 with a turnover growth rate of 1.31 and a size of $1.7831 billion (IBISWorld.com, 2016). Coca-Cola Amatil Limited has an estimated market share of 15.3% in this industry (IBISWorld.com, 2016). Over the past five years, from 2012 to 2017, CCAs alcoholic segment has been performing well despite a reduced consumption which has slowed growth rate. According to IBISWorld.com (2016), CCAs revenue in this industry is expected to increase at an annual rate of 3.3% through December 2017. The primary competitors are Diageo Australia Limited and Asahi Holdings (Australia) Pty Limited. Diageo and Asahi Holdings have market shares of 23.6% and 12.3% respectively, implying that Diageo is the market leader followed by CCA. Fruit and Vegetable Processing in Australia The company ventures in the fruit and vegetable processing through its subsidiary company called SPC Ardmona (IBISWorld.com, 2016). The subsidiary processes a broad range of fruits and vegetable products for sale in various retail stores. The companys performance in this segment has been hampered by cheap imports from South Africa and Italy (IBISWorld.com, 2016). There has also been a competition between the major supermarkets such as Woolworths and Coles, which has also led to the reduction in prices of the products. The industry size is estimated to be $5.8864 billion with a turnover growth rate of 0.29. CCA has a market share of 5.7%. Other players in the Industry are Simplot Australia Pty Limited and Heinz Watties Pty Limited with market shares of 8.1% and 6.6% respectively (IBISWorld.com, 2016). Coca-Cola Amatil has been struggling to cope with the competition over the past five years. Generally, it has been underperforming due to oversupply from cheap imports. Extreme weather has also affected the company since it has reduced fresh produce.   In 2013, the total revenue was 319.8, up from 317.2 in 2012. There was also an increase in 2014, but the revenue decreased in 2015 which was recorded to be 319.6 down from 328.1 in 2014. The revenue in 2016 rose to 332.4. Soft Drink Manufacturing Coca-Cola Amatil boasts being the largest soft drink manufacturer in Australia with a market share of 53.8% (ibisworld.com, 2016).   Its rival, Asahi Holdings Pty Limited has a market share of 24.9%. Historically, the performance of CCA has been strong. However, high competition and shift of customers preference of soft drinks due to health concerns have significantly affected the revenue.   Despite being the market leader in the industry, CCA has been underperforming over the last five years. The companys revenue has been falling due to pressures from competitors and marketing costs. According to IBISWorld report (2016), the revenue increased between 2011 and 2012. From 2012 to 2016, the profits have sharply decreased. Overall Company Performance In overall, CCA has been performing relatively well considering the fact that its main business segment has the highest market share in Australia. Sales Revenue According to Saunders Cornett (2014), sales revenue refers to the net income from the sales of goods or services after all the costs have been subtracted. Over the last five years, CCA has been recording an unstable growth in sales revenue. As at December 2012, the sales revenue was $5,097,400. This was followed by a drop in 2013 which recorded sales revenue of $5,036,400, a growth rate of -1.2%. In 2014, the sales revenue grew at a rate of -1.9% to $4,942,800. This was the lowest figure in the span of five years. In 2015, CCA did a lot to achieve high sales revenue of %5,093,600,000 which is equivalent to a growth rate of 3.1%. In 2016, the sales revenue changed positively at a rate of 1.1% to record a figure of $5,150,800,000 (ibisworld.com, 2016). Although the sales growth rate seems to be staggering, the average growth of sales revenue from 2011 to 2016 is 1.4%. Total Revenue Saunders Cornett (2014) define total revenue as the income of a company from all sources, including the sales revenue, in a given period. The figure includes the sales revenue and revenue from other sources. Just like the sales revenue, CCA has had unstable total revenue since 2012. The company recorded $5.175 billion of total revenue in 2012 (ibisworld.com, 2016). In 2013, the total revenue dropped by 1.1% to record $5.1199 billion (ibisworld.com, 2016). In the following year, a further decline in total revenue was also realized, at a staggering figure of $5.0341 billion, which was a drop by 1.7% (ibisworld.com, 2016).   In 2015, CCAs total revenue increased at a rate of 3% to become $5.1869 billion by the end of the year (ibisworld.com, 2016). By the end of 2016, the total revenue was recorded as $5.2532 billion, which was an increase of 1.3% from the previous year. On average, the percentage change in growth rate since 2011 is 1.5%, implying that the company is on the righ t track. However, comparing to the average growth rate in the industry which was 2.36% in 2016, the company has been underperforming. Net Profit after Tax (NPAT) Net Profit after Tax (NPAT) is the amount of money a company earns after all its expenses (Saunders Cornett, 2014). Coca-Cola Amatil Limited has been hit by fluctuations in profits, and its profits have generally been decreasing sharply from 2012 to date. In 2012, the net profit after tax was $457.8 million. This was followed by a sharp decrease in 2013, which was $79.9 million, which is a percentage decrease of 82.5% (ibisworld.com, 2016). In 2014, the profits increased more than twice and reached $272.1 million, which is 240.6% growth. The profits grew further by 44.6% in 2015 but, as of 2016 December, the profit was $246.1 million as opposed to $393.4 million in 2015, which was a decrease of 37.4% (ibisworld.com, 2016). On average, CCA has not been doing well regarding profits. Its average change in NPAT is -16.1%. As of December 2016, the industry average NPAT was 4.99%, implying that CCA has been performing poorly. Return on Revenue (ROR) To understand the profitability of CCA, it is essential to look at the change in ROR. In 2012, the change in ROR was 8.9% (ibisworld.com, 2016). In 2013, 2014, 2015 and 2016, the ROR was 1.6%, 5.4%, 7.6% and 4.7% respectively (IBISWorld.com, 2016). This implies that the company was more profitable in 2012 and 2015 compared to the rest of the years. Return on Assets (ROA) The ROA measures the profitability of a company in relation to its assets. CCA has been doing well since it has been recording a positive ROA since 2012. Coca-Cola Amatil Limited management team can be said to be efficient in utilizing assets to generate revenue. From 2012 to 2016, the Return on Assets is 6.8%, 1.2%, 4.5%, 5.9%, and 3.8% respectively. The average ROA in the industry as at 2016 was 1.9% compared to CCAs 3.8% (IBISWorld.com, 2016). The company has, therefore, been performing well in the industry. Question 2 Robert Alba just won the state lottery. He has been given the option of receiving either  $62.9 million today or $5 million a year for the next 35 years, with the first payment paid  today. Discuss the process that Robert should use to determine which payment option he  prefers. Ignore all taxes and assume that Jesse will live for at least 40 more years Solution To determine the best option, we need to determine the present value the Annuity due of for the given cash flows since the payment in the second option is going to be made at the beginning of the period. Present value or the discounted value refers to the current worth of the given amount of money or the stream of cash flow that is going to be received in future at a particular rate of return (Brealey, Myers, Allen, and Mohanty, 2012). The present value is usually less than the future value due to the time value of money characteristic, which states that money will always earn an interest; therefore, a dollar today is more than a dollar tomorrow. The formula is as follow; (Brealey, Myers, Allen, and Mohanty, 2012) Where C=the cash given per period i = rate of interest n= the number of payments In this case, the present value of $62.9 million today is $62.9 million. Robert Alba should determine the present value of the cumulative cash flows of $5 million per year for 35 years.   The best option would be that with the highest present value. Using the formula above, the present value for option B will be as follow; Assuming a uniform interest rate of 10%, $53.04 million is less than $62.9 million; therefore, Robert Alba should choose option A, i.e. to receive the payment of $62.9 million now.

An Analysis of Joyce Carol Oates’ Where Are You Going, Where Have You

An Analysis of Joyce Carol Oates’ Where Are You Going, Where Have You Been Joyce Carol Oates is one of the most productive writers of our time. Between 1971-95, Oates published twenty-five novels, eighteen short story compilations, three collections of novellas, five volumes of poetry, six editions of plays, eight books of essays, and countless more umcollected works (Kellman 487). As the format for her writing varies, so does her subject matter. Her creations cover a wide range of genres, but Oates' main fascination is contemporary America with its "colliding social and economic forces, its philosophical contradictions, its wayward, often violent energies" (Johnson 8). Oates' works, and somethimes even Oates herself, have been subject to responses ranging from extreme praise to harsh criticism from the literary community. Oates has won many significant literary awards and has even been nominated twice for the Nobel Prize in literature but has also received her share of bad press. Oates' work has time and time again been criticized for being too violent, to o bizarre, degrading to women, and "the exact antithesis to the feminist movement" (gtd. in Wesley par. 32). I believe the opposite is true. Oates herself has been quoted as saying that her subject matter is "today's culture," and that all she is trying to do is to bring the ills of our cuture "to a place where it can be examined" (Johnson 10). Some of her stories are purely fictional, but many stories seem to be ripped from the headlines. Zombie, a 1995 novel, is loosely based on the Jeffrey Dahmer serial killings (Seltzer 288). The highly acclaimed short story "Where Are You Going, Where Have You Been?" draws its inspiration from the case of an Arizona serial killer,... ...arterly Review 38 (1999): 487-495.

Hotel Management System Essay

1.1 Introduction The aim of every business is to achieve operational excellence and efficiency. The effectiveness of business processes today has been influenced by technology. However, as computing technology becomes increasingly vital to conducting business and communicating with associates, new and more complex issues must be resolved. Among them is the need to ensure that the benefits derived from using computers are not reduced due to accompanying information management inefficiencies or to the creation of new business risks. A hotel is a building where travelers can pay for lodging, meals and other activities. Hotel Management involves combination of various skills like management, marketing, human resource development, and financial management, inter personal skills, dexterity, etc. Hotels are a major employment generator in tourism industry. Hotel management can be a very lucrative field, both in terms of annual revenues Furthermore, hotels are big attractions to businesses and associations l ooking to hold events. Booking an event means additional revenue for the use of a conference or banquet room, in addition to overnight guests who may use laundry and other concierge services. Work in the area of Hotel Management involves ensuring that all operations, including accommodation, food and drink and other hotel services run smoothly. Hotel management system goes a long way to assist hotels in achieving its aims. Hotel management system as an automated system will enable hotels provide all round services to their various customers or stakeholders through digital or electronic means. The system will assist management in its day-to-day business activities, make decisions. 1.2 Subject and Field of Study The field of study is computer studies and in relation to the subject area being Information Management system and Web Application Development with highlights on Database management, Web and Internet Technology. This project is a web application development project prior to my area of study, the project is designed specifically for hotel businesses that has seen the need of transforming business activities from the manual process to digital process and also businesses that needs safe and proper customer data management in electronic form using the internet. 1.3 Study Objectives The study objectives are categorized into two: 1.3.1 Global Objective: The Global objective of this project is to contribute to the general body of knowledge and research work in the area of developing a hotel management system that will automate the whole management processes of the organization (hotels). 1.3.2 Specific Objectives: The following are the targeted objectives to be accomplished in order to achieve the general objective above. To be able to create mutual communication between customer and business (hotel). To provide a platform for online booking and reservation by customer’s rooms. To provide easy access to customers in viewing and making selection of hotel rooms. To be able to manage fast access to guest(customers) information and easy update of records. To be able to provide security measures to access the hotels information lowering data security threats. To be able to provide better data management facilities To able to enable backups of respective users to be made and accessed when it is needed. 1.4 Problem Statement Intended to explore the impact of the design of Hotel Management System is expected to overcome the general problems in handling issues relating to hotel business activities, managerial activities, difficulties in providing stock control of equipment’s used in the hotel, difficulties on monitoring and tracking customers details and requirements on which the tasks are performed, the time consuming aspects of various customers moving all the way to the preferred hotel to make reservation and bookings as well as viewing at the hotel rooms available. However providing notifications to respective customers about their reservation status is also time wasting. Also management of these hotels finds it difficult manually keeping records of their various employees, clients and other vital hotel related information. Difficulties in making references to old business transactions, data’s and other negotiations and issues concerning security of data and  recovery manners is also considered. It is designed to replace old method of recording information by using pen and paper. 1.5 Research Methodology The proposed research methodology for this project is the â€Å"Waterfall Model†. The waterfall model takes fundamental process activities and it is a sequential design process, often used in software development processes, in which progress is seen as flowing steadily downwards (like a waterfall) through the phases of separate process phases such requirement specification, software design implementation, testing and maintenance. To ensure that our project is in par with our client needs, we used the waterfall model approach in developing the systems. The first process of the model is data gathering. Here we gather information about basic hotel management system functionalities. Joint Application Development (JAD) will be used as fact- findings techniques that will be used to gather the requirements analysis if the Hotel Management System should be implemented in any hotel. After the first phase of data gathering we proceeded in interviewing our clients. We asked about what their expectations were in a hotel management system. Some clients already had a hotel management system. In this case we asked them about what improvements they would have wanted to add in the system such as implementing an attribute for passport information. After gathering all of the information from our clients we proceeded with the next step which is analyzing of data and problem solving. In here we began conceptualizing the components our system needed such as inputting name and creating a log in log out system. We also thought about what elements from our initial concept did not require. After conceptualizing all of the elements we need in creating our system we proceed to the next step which is implementing requirements. In here we decide what applications we need in developing the system. Here we decided to use VB.Net and MySQL as our primary programming languages. Now that we have our tools we proceed to the next step which is system and software design. In here we take our concept design and upgrade that design by implementing our tools in the design. This means we have to understand the requirements of the end user and also have an idea of how the end product should look like. System design also helps us specify the hardware and  system requirements to create the overall system architecture. System design is the (stepping stone towards) our next task which is GUI design. GUI design is the process of designing user interface of the entire system. This means that we start creating actual look of the program for our system. After creating the design we proceed to next step which is system coding. This is where the command lines are assigned to a GUI so that they would have their proper functions. An example would be initiating the connection query in order to connect to the database. After adding all of the required components we proceed to the final step which is system testing and debugging. Here both individual components and the integrated whole are methodically verified to ensure that they are error-free and fully meet the requirements. 1.6 Background and Justification of the Study The purpose of this study is to investigate the extent to which a hotel management system will be used in the organization to manage hotel business processes. A background study shows that the hotel’s daily operation is managed by the Administrative Department. The process starts from customers coming to the hotel to make reservations and enquiries, through the hotel receptionist. The customer booking details will be recorded in a manual form and filed. After making enquiries and finally a reservation is made, the reservation form would be forwarded to the cashier for payment to be made, all involving paper work. Since it involves paper work lots of time is consumed and booking & reservation takes a lot of time. Furthermore, when a customer wants to check out, files will have to be searched and retrieved so that the final operations of checking out a customer will be performed. Some of the service personnel who have studied the issues concerning the manual business operation issued by customers, has contended that the manual operation reduces the operational productivity of the hotel. Because there have been cases records have been mishandled due to human error, some data’s cannot be found etc. HMS helps in managing reservations, bookings, guests and agents. The user can search for the vacant rooms in the hotel and book for it by not necessarily coming to the  physical location of the hotel. An administrator can view the booking details, transactions and coordinate the activity with the agents. He can track the entire site activity. Reservations can also be made through a phone call or an email. 1.7 Expected Outcome of the Project At the end of this project, the following becomes the outcome: There will be a created mutual communication between customer and management. Customers will be enabled make online booking and reservation by searching for rooms. There will be enabled effective storage of customers’ data Administrators will be able to manage fast access to guest files and updates of records will be done effectively and efficiently. Administrators will be provided with better data management facilities. There will be enabled security measures when trying to access the hotels information lowering data security threats. There will be enabled frequent backups of respective user details and access when needed. 1.8 Presentation of Thesis Chapter 1: General introduction is focused on the research which is the Project Proposal. Chapter 2: Literature Review which focuses on history and the outlook of the existing systems. Chapter 3: Methodology. In this chapter, the proposed system is analyzed into details and its importance discussed expansively where context level diagrams, dataflow diagrams, flowcharts will be used to explain the proposed system further. Chapter 4: System Analysis and Design; the study carries on with the design of the system. This chapter will encompass database modeling, class modeling, use case modeling and the relationship diagram of the proposed system. Chapter 5: Testing and Implementation; Implementation of the computer software goes on after the design. The system will be tested and reviewed to reveal errors. In this chapter also the documentation of the completed system. It also lays emphasis on both the users of the system and the system itself. Under the user documentation, the manual for both the user and the expert who will administer the system will be known. Finally conclusion and recommendation will be made as well as observations are identified and the necessary improvement which could be added to the system is made.

Thermal Pollution Essays

Thermal Pollution Essays Thermal Pollution Paper Thermal Pollution Paper It is one of the pollution that effects on living things and the environment badly. The definition of thermal pollution is the degradation of water quality by any process that changes ambient water temperature. A common cause of thermal pollution is the use of water as a coolant by power plants and industrial manufacturers. When water used as a coolant is returned to the natural environment at a higher temperature, the change in temperature decreases oxygen supply, and affects ecosystem composition. Urban runoff?seawater discharged to surface waters from roads and parking lots-can also be a source of elevated eater temperatures. When a power plant first opens or shuts down for repair or Other causes, fish and other organisms adapted to particular temperature range can be killed by the abrupt change in water temperature known as thermal shock. * Effects of thermal pollution on the environment There are several effects of thermal pollution * The dissolved oxygen content of water is decreased as the solubility of oxygen in water is decreased high temperature * High temperature becomes a barrier for oxygen penetration into deep Goldwater. * Toxicity of pesticides, detergents and chemicals in the effluents increases with increase in temperature. * The composition of flora and fauna changes because the species sensitive to increase temperature due to thermal shock will be replaced by temperature tolerant species. Metabolic activities of aquatic organisms increase at high temperature i nadequate more oxygen level falls under thermal pollution. * Discharge of heated water near the shores can disturb spawning and can Bienville young fishes. * Fish * Sudden migrations are affected due to formation of various thermal zones and periodic increase in temperature producing a thermal effect * Distribution of organisms among major and minor communities. Changes to reproductive powers and increased susceptibility to disease * production of heat shock proteins for thermonuclear. Bio indicators are the first to show the effects. * Decrease in productivity of the water body . * Economic and environmental damage * Effects of thermal pollution on the living things All plant and animal species that live in water are adapted to temperatures within a certain range. When water in an area warms more than they can tolerate, species that cannot move, such as rooted plants and shellfish, will die. Species that can move, such as fish, will leave the area in search of cooler notations, and they will die if they can not find them. It can be said that pollution is the introduction of contaminants into an environment that causes instability, disorder, harm of discomfort to the ecosystem and in this essay on pollution these problems will be discussed. The blacksmith institute issues annually a list of the worlds most polluted worst places. In 2007 issues the top ten nominees are located in Azerbaijan, china, Peru, Russia, Zambia including India. In the last industrial age, the term over pollution was common, representing a view that was both critical of industrial pollution but likewise accepted a certain degree of pollution as nominal industrial practice.

Financial Management Essay Example | Topics and Well Written Essays - 1250 words

Financial Management - Essay Example The company is deemed to be the third largest retailer with respect to the amount of revenue that it produces (Potter, 2011; Deloitte, 2010). To examine and analyze the financial performance of the company, the ratio analysis technique needs to be used. Ratio analysis is a technique which uses a set of different financial measures known as financial ratios, in order to analyze the financial performance of a company. These financial ratios of the company would be compared with its prior year ratios to understand whether there is any improvement in the performance of the company (Shim et al, 2000). The financial ratios for Tesco plc are as follows: Ratios 2010 2009 Liquidity Ratios Current ratio 0.73 : 1 0.75 : 1 Quick ratio 0.44 : 1 0.61 : 1 Gearing Ratios Gross debt-equity ratio 74.9% 109.6% Net interest cover 3.1 times 7 times Profitability Ratios Gross Profit Margin 8.22% 7.76% Net Profit Margin 4.1% 3.99% Investment ratios Earnings per share 29.33 cents 27.50 cents (Annual Report, Tesco plc, 2011) . Liquidity Ratios evaluate a company’s ability to pay off their debts when they fall due. Basically it gives a basic picture of a running position of a company. Current ratio illustrates a company’s ability to pay off its short term obligation/ current liabilities (amount due within 12 months time) with the current assets that it holds whilst the quick and the cash ratio illustrates a company’s ability to pay off their debts with the most liquid assets and cash respectively. Current ratios on the other hand analyze a company’s ability to pay off their respective debts/liabilities through their most liquid (easily converted to cash) assets. The ratios in the above table indicate that the liquidity position of the company has worsened in 2010 as compared to 2009; both the current and the quick ratios have deteriorated over the year. The current ratio has fallen from being 0.75:1 in 2010 to 0.73:1 in 2009. The quick ratio has also fallen f rom being 0.61:1 in 2010 to 0.44:1 in 2009. This should be a concern for the company as the liquidity ratios are a measure of company’s subtleness and long term sustainability. With the help of the profitability ratio, a company can ascertain the increase/decrease in the level of costs, revenues and profits over any given period of time. These ratios help in ascertaining the company’s performance with respect to the profits that the company/organization has generated. Gross Profit Margin/Net Profit Margin ratios help in ascertaining a company’s gross profit/net profit with respect to the revenue that the company has generated; this ratio helps in understanding the changing trends of the operational costs within any particular period of time. Both the Gross Profit and the Net Profit margin ratios have improved for the company over the one year concerned. This is a good sign for the company with respect to its growth, the company’s gross profit margin has i mproved from being 7.76% in 2009 to 8.22% in 2010, this is both because of the fact the company has increased its sales revenue and it has controlled its cost as well. The net profit margin has also increased from being 3.99% in 2009 to 4.1% in 2010, although the change is not a huge one but still for a large company like Tesco plc, this change is worth noting as it has increased the company’

The Madness of John Brown Essay Example for Free

The Madness of John Brown Essay Historians are not the only ones that can elucidate history. History is a extensive puzzle that can be solved by anyone who has an educated diploma on certain subjects. Historians are the main disposition to solve the uncertainty of history with their useful, quality skills of making theories to conjoin loose ends of history, motivation of repeated research, and their undying love to learn new history, but a psychologist can solve history too with their forte. Even though it may seem absurd to believe that this occupation who assesses a mans personality to solve problems; a psychologist can solve an dead mans prospective in life. A letter is a common communication device in the old days and can be read by anyone. A historian would try to find key words in the letter to guesstimate the situation, but a psychologist knowing the mysteries of attitudes and behaviors of people would look at double meanings in passages. Two perceptions are better than one and knowing the true motivation of a persons mind than their careless actions can give an different outlook of a case. Other specialists can help historians find the gist of John Brown rationale of being insane in the terms of slavery and why he killed five men in the open. Although John Brown never underwent a psychological examination about his childhood, he had left a letter with important information of his childhood into a story. Psychoanalytic insight has helped to reveal some of Johns most intense personal conflicts from this letter; his ambivalence toward his fathers strict discipline, the paradox of Browns struggle to internalize and accept his fathers authority in order to become independent himself, and his main concern with property and pets as a means of defining his independence. This ambivalent father-son relationship suggests that Browns intense life-long identification with black slaves might well have sprung from the struggle he experienced with paternal discipline. Helping slaves was ultimately a means of helping himself without consciously recognizing the source of his emotions and convictions. He could have channel the repressed hostility toward his father toward the slaveholders. In conclusion, psychologist has added the tool of psychoanalysis in the study of history. This tool has helped historians to go beyond rational motives in understanding people who have changed society and history in either a good or bad way. History has somewhat gotten more clearer and truthful thanks to psychologists.

Source Of Mechanical Energy Engineering Essay

Source Of Mechanical Energy Engineering Essay Introduction Electricity is a basic part of nature and it is one of our most widely used forms of energy. It is a secondary energy source that we get it from the conversion of other sources of energy, like coal, natural gas, oil, nuclear power and other natural sources, which are called primary sources. Many cities and towns were built alongside waterfalls (a primary source of mechanical energy) that turned water wheels to perform work. Electricity consists of the presence of electric charges, as well as the flow of those charges. There are three forms of electricity. One form is static electricity, which is the presence of either positive (+) or negative (à ¢Ã‹â€ Ã¢â‚¬â„¢) electric charges in or on an object, usually a non-conducting material. The second form of electricity is the flow or movement of free electrons through a conducting material, such as a metal wire, toward an area of positive electric charges Electricity appears in two forms: alternating current (AC) and direct current (DC). Direct current does not change directions the electron flow is always from the negative pole to the positive pole although as we mentioned before, the electrons themselves dont really move, its the holes that are created that move. Direct current is almost always what is used inside of electronic devices to power the various internal components, but it is a harmful thing in audio signals, which are alternating current. Alternating current (AC) electricity is the type of electricity commonly used in homes and businesses throughout the world. While direct current (DC) electricity flows in one direction through a wire, AC electricity alternates its direction in a back-and-forth motion. The direction alternates between 50 and 60 times per second, depending on the electrical system of the country. AC electricity is created by an AC electric generator, which determines the frequency. What is special about AC electricity is that the voltage can be readily changed, thus making it more suitable for long-distance transmission than DC electricity. But also, AC can employ capacitors and inductors in electronic circuitry, allowing for a wide range of applications. Direct current or DC electricity is the continuous movement of electrons from an area of negative (à ¢Ã‹â€ Ã¢â‚¬â„¢) charges to an area of positive (+) charges through a conducting material such as a metal wire. Whereas static electricity sparks consist of the sudden movement of electrons from a negative to positive surface, DC electricity is the continuous movement of the electrons through a wire. A DC circuit is necessary to allow the current or steam of electrons to flow. Such a circuit consists of a source of electrical energy (such as a battery) and a conducting wire running from the positive end of the source to the negative terminal. Electrical devices may be included in the circuit. DC electricity in a circuit consists of voltage, current and resistance. The flow of DC electricity is similar to the flow of water through a hose. Electrical Wiring Electrical wiring system is a network of electrical conductors for carrying electrical current to the electrical equipment involved. This method is related to the wiring system for buildings in Malaysia. In Malaysia, the electric wiring system is subject to the rules established by the Energy Commission as provided under the Electricity Supply Act 1990, Electricity Regulations 1994, the MS IEC 60364:2003 Standard Electrical Installations of Building, MS 1936:2006 Electrical Installations of Building Guide To MS IEC 60364 and the MS 1979:2007 Electrical Installation of Building Code of Practice. Wiring systems used in Malaysia is very similar to the electrical wiring standards used by the United Kingdom but by the standards of the wire conductor already changed. NEW TOWN DEVELOPMENT SDN BHD PROJECT The high-rise building electrical system For The New Town Development Sdn Bhd project, this building was a high-rise commercial building. The building comprises of 4 storey basement parking and 7 storey shopping complex and the rest are offices lot. So, for the electrical installation should at every floor there were a number of electrical panels to serve all the lighting and power requirements on that floor including the lighting, switched socket outlets, toilet exhaust fans and anything else. Some areas of the office used an open floor office systems so under floor trunking was also used here. Besides, a few of the panel were located inside the riser room of each floor. However, since each was a large area some panels needed to be located at the office area. Wiring directly from the electrical riser would be unnecessarily too long. Therefore, the electrical consultant locates these electrical panels along the corridors throughout the building. The design architect was requested to provide small rooms to house the panel. Alternatively, small electrical cabinets with lockable doors and sufficient work access and ventilation would be acceptable. If the planned building is very high example like 40 storey office building or in cases where heavy loads are located at higher levels of the building, it may be necessary to provide substations at the higher levels of the building. For the 40-storey office building, an 11/415 kV substation may be necessary at one of the upper floor. It may be located at twentieth floor, for example. All the electrical substation room spaces as explained earlier will then need to be provided except the authoritys electrical rooms. The floors of this substation would then need to be specifically designed by the appointed structural consultants to handle the loads of all the substation equipment. Based on the structures and other factors was related. We propose the installation of electricity for this building using the radial system and ring main system. Because its easier to maintain and simple system for the design and construction. In addition, using the rising main distribution system is important because the building is more than 5 levels. So, to distribute electric power at every level is appropriate to use the rising main for the building. Basement A basement is one or more floors of a building that are either completely or partially below the ground floor. Basements are typically used as a utility space for a building where such items as the furnace, water heater, breaker panel or fuse box, car park, and air-conditioning system are located; so also are amenities such as the electrical distribution system, and cable television distribution point. In British English the word basement is used for underground floors of, for example, department stores but is used for a space below the ground floor of a house only when it is habitable, with windows and (usually) its own access. The word cellar is used to apply to any such large underground room. Subcellar is a cellar that lies further underneath. Based on the planned building project, the level of 1st to 4th is the basement. In part this is a car park. Therefore, we recommend the installation of electricity in the area using ring system. Ring system is ideal because in this part do not use electrical appliances and many others. Basement car parks.jpg Basement pendlehill1.jpg Basement Ring Main System in Basement A ring main wiring circuit is the alternative to a radial wiring circuit. In a radial wiring circuit, the wiring starts at the circuit breaker and connects to each device on the circuit (fans, outlets, lamps, etc) in turn. When it reaches the last device, the wiring simply ends. Ring main wiring goes one step further instead of ending the wiring at the last device; it pulls more wiring back from the last device to the circuit breaker, completing a loop. Ring main wiring is required in some places, and illegal in others. The main advantage to a ring main system is smaller wiring. Since each device on the ring has two hot wires connecting it to the circuit breaker (one on each side of the loop), smaller wiring can be used to safely carry the electric current. Smaller wire is both cheaper and easier to work with. It bends more easily, can be pulled around corners with less effort, and is easier to fit into the screws and connectors you need to attach it to. One other advantage is wiring distance. Wire has some small amount of resistance, and the longer the wire goes to reach the device it is powering, the more resistance it has. This results in a voltage drop over the length of the wire run (by Ohms Law), which could affect the operation of your electrical devices if it drops too low. The maximum distance from the circuit breaker around the ring is the midpoint of the ring, while the maximum distance in a radial circuit is the end of the chain. In this manner, the ring setup effectively cuts the distance to the farthest device in half. The radial system does have one advantage over ring main. If a break were to occur somewhere in the wiring loop of a ring main system, you wouldnt know it. Everything would still function normally because it is still powered from one end. However, this means that if you took advantage of the ability to run smaller wiring (and everyone does), your wire is now undersized for the current it is expected to handle because the system is no longer powered from two wires, only one. This can result in overheating of the wires, which in turn breaks down the insulation and can start a fire. In electricity supply, a ring final circuit or ring circuit (informally also ring main or just ring) is an electrical wiring technique developed and primarily used in the United Kingdom that provides two independent conductors for live, neutral and protective earth (ground) within a building for each connected load or socket. 557px-Ring_circuit.svg.png ring distribution Ring Main Distribution Size of cable used to ring system is 2.5 mm2. Installation Rules of Ring System at basement Rules for ring circuits say that the cable rating must be no less than two thirds of the rating of the protective device. This means that the risk of sustained overloading of the cable can be considered minimal. In practice, however, it is extremely uncommon to encounter a ring with a protective device other than a 30 A fuse, 30 A breaker, or 32 A breaker, and a cable size other than those mentioned above. The IEE Wiring Regulations (BS 7671) permit an unlimited number of socket outlets to be installed on a ring circuit, provided that the floor area served does not exceed 100 m2. In practice, most small and medium houses have one ring circuit per storey, but for this building should having more. An installation designer may determine by experience and calculation whether additional circuits are required for areas of high demand; for example, it is common practice to put kitchens on their own ring circuit or sometimes a ring circuit shared with a utility room to avoid putting a heavy load at one point on the main downstairs ring circuit. A heavy concentration of load close together on a ring circuit can cause minor overloading of one of the cables if near the end of the ring, so kitchens should not be wired at one end of a ring circuit. Unfused spurs from a ring wired in the same cable as the ring are allowed to run one single or double socket (the use of two singles was previously allowed but was banned because of people replacing them with doubles) or one fused connection unit (FCU). Spurs may either start from a socket or be joined to the ring cable with a junction box or other approved method of joining cables. Triple and larger sockets are generally fused and therefore can also be placed on a spur. It is not permitted to have more spurs than sockets on the ring, and it is considered bad practice by most electricians to have spurs in a new installation (some think they are bad practice in all cases).Where loads other than BS 1363 sockets are connected to a ring circuit or it is desired to place more than one socket for low power equipment on a spur, a BS 1363 fused connection unit (FCU) is used. In the case of fixed appliances this will be a switched fused connection unit (SFCU) to provide a point of isolation for the appliance, but in other cases such as feeding multiple lighting points (putting lighting on a ring through is generally considered bad practice in new installation but is often done when adding lights to an existing property) or multiple sockets, an unswitched one is often preferable. Shopping Complex Based on commercial building a project was planned by the New Town Development Sdn Bhd. A 40 storey high building will put the shopping complex of seven stories are starting at level 5th to 11th. Thus, the electrical installation for this we propose to use a radial system. We feel the radial system is suitable for shopping complex. Because there are a lot of use of electrical appliances such as lights, air conditioners and so on. In addition, the radial system is easy to designed, built and maintained. Shopping Complex at level 5th Shopping Complex at level 5th 8th Offices In this building project, a total of 29 levels will be provided for offices start from level 12th to 40th. Based on this, we agreed to use the same method of electrical installations such as shopping complexes, namely the radial system. This method is ideal because it is easy to maintain. In addition, if there is damage to the wire. It is easily known and easily repaired than the ring system. Office Radial System in Shopping Complex and Offices The radial system is widely used, economical systems often found in low-load density areas. To reduce the duration of interruption, overhead feeders can be protected by automatic reclosing devices located at the substation or at various locations on the feeder. This device reenergizes the feeder if the fault is temporary. To further reduce the duration and extent of customer interruptions, sectionalizing fuses are installed on branches of radial feeders allowing unaffected portions of a feeder to remain in service. Radial distribution systems are the simplest systems to plan, construct, and maintain, but are also the least reliable because of the radial nature of the design being served from a single source at a time. If any part of the system experiences a failure, some or all of the customers served by the radial feeder will be without power until a repair is completed. Straightforward design, lower cost, and decent reliability are the distinguishing characteristics of the RDS. An auto-loop distribution system is a special type of radial distribution system and is differentiated by having two feeders that tie to a customer load. The auto-loop system automatically senses the loss of one source of voltage and quickly and automatically switches the load to the second feeder. This type of system adds reliability benefits by keeping outages to a few seconds (or less) but the added cost of having two sets of utility equipment at one location, could be as high as hundreds of thousands of dollars for each installation. radial distribution Radial System Radial system distribution Size of cable commonly used for circuit radius is 4 mm2 Rising Main Distribution for commercial building For multi-storey buildings such as this are ideal to use the rising system. This is because, to ensure that each level of the building is fully supplied with electricity from renewable sources of electricity. A riser is a feeding cable or pipe giving supply to upper floors of a multi-storey building (high rise building). The above picture shows a typical installation of bus duct rising mains in the riser room at individual floor of a high rise building (The Bus duct was taken in the riser room at one of the upper floors of a high rise building). Most of the major components of a bus duct riser system. In electrical works, a riser is a set of cables the supply the upper floors. The feeding cables rise up straight to the top floor. Then at each floor a tap-off unit is connected so electricity can be supplied to that floor (for this project, we propose the radial distribution system). An alternative is to run one individual set of cables to each floor. Then there would be many cables that need to be installed the number of which is directly proportional to the number of upper floors. There are actually three risers, first one is the normal main electricity supply. This supply is just the normal authority supply like the one you have in your house. The 100A tap off unit is for this riser. The second tap off, which is one of the 60A units, is what is called essential supply, or emergency supply. It is a normal authority supply like the one you have from the 100A tap off unit above. However, it is also backed by a standby diesel generator. This means that if the electricity supply from the authority distribution network fails due to problem with their underground distribution cables or whatever, the standby electric generator would kick in and switch in the locally generated electricity to this electrical riser. Large capacity electric generators are expensive. Therefore, it is not economical to supply all electricity needs in the building from this generator. That is why separate electrical risers are used, and the normal riser is not backed by the generator supply. The third tap off unit (the second 60A unit) is for the air conditioning system. It is quite common (and is considered a better design) to have a separate feeder cable for the air conditioning and mechanical ventilation (ACMV) system in a large building. That is the reason for the third electrical riser here. rising main detail Rising Main Distribution Rising main distribution is use to distribute 415v 3-phase electricity from main distribution board to all floors. The copper vertical bus bars which run up in electricity cable riser. The vertical duct or trunking to the height of the building. To prevent the spread of fire and smoke, fire barriers are incorporated with the bus bar chamber at each compartment floor level. One more point to note here is that some office buildings use the generator-backed supply example like essential supply to feed the electrical riser for the air-conditioning system. With this arrangement, ACMV equipment that need to continue operating even during the mains failure do not need to be connected to ESSENTIAL supply riser, which is why it is given a separate riser in the first place. Observe the large flexible conduits coming out from the bottom of the tap off units and connect to the orange-colored electrical trunking. Some installations use rigid metal trunking for this purpose. Cables are run from a tap off unit into the flexible conduit to go to the orange metal trunking. They run inside the trunking to connect to the respective sub-switchboard. The switchboard for the air conditioning system is normally located inside the AHU room of that particular floor. From the sub-switchboards, separate outgoing cables are run inside the trunking to connect to separate distribution boards (DB) on that particular floor. Even though electrical installations at hospitals are relatively much more complex than the office building above, the installation at their hostel and staff quarters buildings are usually very simple. https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEjripe6ufY0gigmVsNjD9SQs7MJp7iLacIO0uhxlmWgYm1bKdxEnew7OcUlb1XfgP0_aQxB99oeTInbAS2oebUxamN9-w6Gm3xAik1WF6g-z7XgNQ1mV1AkQLsJGwee7uWr22znnXoiJiM7/s320/Floor+Sub-switchboard+Picture.JPG Typical bus duct rising main at individual building floors https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhEm4RiMp_kCyx7MKzY7k6JJ2oi4vPlCtyLoP-Itq4Wq4c0ldyyNX6HEGaitzpQZAdUGd1PpG5eQaw_0K2QMZ3iuS2-nZnMMBD6Y4iheY5aPxXFv3hdVbJ57Cf_wE3fd_DY0nSxDfpT3FDK/s320/Electrical+Busduct+Riser+Picture.jpg The electrical riser room Basically, there only two new components at each riser, which is the Termination Box (Feed In Box) and the incoming cables that terminate into the termination box. The generator-backed Essential supply cables need to have red colored insulation. It is because this supply is part of the fire emergency system of the building. A fire-rated cable must be able to continue operating for a certain number of hours during fire before it fails. This is the requirement. It used to be MICC (mineral insulated copper cables) cables that play this role, but now people use mostly the fire-rated cables for this purpose except in very special installation condition. The fire-rated cables are cheaper, easy to install and maintain. The black-colored cables are from the Normal supply. That means the other ends of the cables are connected to the Normal Supply main switchboard. While the red cables are connected to the Essential Supply main switchboard. Which means the Essential Supply main switchboard is the one that is backed by the standby electric generator. https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhZeC31yP8mQDt4F7iSpiLS-EJC5B5OfX-_8vm1zqTZVJyucb7C_T30rMneTML6C7bsEnK0_Pfqrhby15E8icS5T9NL1gfkjKoeoUgk_saH5BnVmi8l26GoU_L5APGAcSk6huf1w_0_JLTi/s320/Busbar+Trunking+Picture.jpg The bus duct risers at riser room https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhd5M0E1DCYDMNDD58eVabbypxdP8wj-p8C61Mn2t7mYjuvap3CX-wv2QHAATsToEsfkSDglguvNYORPtYpNwZFznp-Sjt9A5LVJpMQCMXkjUJrUQ6ctpgmJkVjUC5iA4th1vS2FjOaLxWE/s320/60+A+TPN+Tap+Off+Unit+Image.jpg The front view of one of the 60A TPN tap off units https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEj23aYHWrba2u5OASaWqbYQjYwZ-qxOT1eEk_xpTc5xZNYpR4lsAaDSr7fjtTtgV0CQkYlxKtHFz5qpLqVAp1UQtoBXq5mbwI6yRqCmZGbgZ0ZUTLdfIoftVVbtp-WBylg2fDxsoI8vsXiW/s320/Busduct+Conductors+Arrangement+Image.JPG A closer view of the vertical bus duct showing the arrangement of the conductors inside Cables and busways A busbar trunking system comprises a set of conductors protected by an enclosure. Used for the transmission and distribution of electrical power, busbar trunking systems have all the necessary features for fitting: connectors, straights, angles, fixings, etc. The tap-off points placed at regular intervals make power available at every point in the installation. A busbar trunking is placed at the offices. http://www.electrical-installation.org/w/images/c/c9/FigE37.jpg Busbar trunking system design for distribution of currents from 25 to 4000A. The various types of busbar trunking Busbar trunking systems are present at every level in electrical distribution: from the link between the transformer and the low voltage switch switchboard (MLVS) to the distribution of power sockets and lighting to offices, or power distribution to workshops. http://www.electrical-installation.org/w/images/3/32/FigE38.jpg Radial distribution using busways at the offices There are essentially three categories of busways that we proposed for the commercial building, that is; 1) Transformer to MLVS busbar trunking Installation of the busway may be considered as permanent and will most likely never be modified. There are no tap-off points. Frequently used for short runs, it is almost always used for ratings above 1,600 /2,000 A, i.e. when the use of parallel cables makes installation impossible. Busways are also used between the MLVS and downstream distribution switchboards. The characteristics of main-distribution busways authorize operational currents from1,000 to 5,000 A and short-circuit withstands up to 150 kA. 2) Sub-distribution busbar trunking with low or high tap-off densities Downstream of main-distribution busbar trunking, two types of applications must be supplied: Mid-sized premises (industrial workshops with injection presses and metalwork machines or large supermarkets with heavy loads). The short-circuit and current levels can be fairly high (respectively 20 to 70 kA and 100 to 1,000 A). Small sites (workshops with machine-tools, textile factories with small machines,supermarkets with small loads). The short-circuit and current levels are lower (respectively 10 to 40 kA and 40 to 400 A). Sub-distribution using busbar trunking meets user needs in terms of: Modifications and upgrades given the high number of tap-off points Dependability and continuity of service because tap-off units can be connected under energized conditions in complete safety The sub-distribution concept is also valid for vertical distribution in the form of 100 to 5,000 A risers in tall buildings. 3) Lighting distribution busbar trunking Lighting circuits can be distributed using two types of busbar trunking according to whether the lighting fixtures are suspended from the busbar trunking or not. Busbar trunking designed for the suspension of lighting fixtures These busways supply and support light fixtures (industrial reflectors, discharge lamps, etc.). They are used in supermarkets, department stores and warehouses. The busbar trunkings are very rigid and are designed for one or two 25 A or 40 A circuits. They have tap-off outlets every 0.5 to 1 m. Busbar trunking not designed for the suspension of lighting fixtures Similar to prefabricated cable systems, these busways are used to supply all types of lighting fixtures secured to the building structure. They are used in commercial buildings (offices, shops, restaurants and etc.), especially in false ceilings. The busbar trunking is flexible and designed for one 20 A circuit. It has tap-off outlets every 1.2 m to 3 m. Busbar trunking systems are suited to the requirements of a large number of buildings. Industrial buildings: garages, workshops, farm buildings, logistic centers, etc. Commercial areas: stores, shopping malls, supermarkets, hotels, etc. Tertiary buildings: offices, schools, hospitals, sports rooms, cruise liners, etc. Examples of Canalis busbar trunking systems http://www.electrical-installation.org/w/images/3/39/FigE40.jpg Flexible busbar trunking not capable of supporting light fittings  : Canalis KDP (20 A) http://www.electrical-installation.org/w/images/5/5c/FigE41.jpg Rigid busbar trunking able to support light fittings  : Canalis KBA or KBB (25 and 40 A) http://www.electrical-installation.org/w/images/b/b3/FigE42.jpg Lighting duct  : Canalis KBX (25 A) http://www.electrical-installation.org/w/images/a/a5/FigE43.jpg A busway for medium power distribution: Canalis KN (40 up to 160 A) http://www.electrical-installation.org/w/images/5/52/FigE44.jpg A busway for medium power distribution: Canalis KS (100 up to 1000A) http://www.electrical-installation.org/w/images/4/47/FigE45.jpg A busway for high power distribution: Canalis KT (800 up to 1000 A) Trunking and Conduit System in Commercial Building https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEiVKZ0EhFztrwVfWNe_DQ-MluHJjQ4W4J1KKzdM0DfyDtf46nRHMml3-8D4hS9rwH0ummYEv-6Gxaz8RPiY67vBu11x5Dh0OMj5nKfXnyDI6R91QwNoMKnx0ySzjLyV6EGstc3OdWpN7Jjz/s320/Mechanical+and+Electrical+Coordination+Picture.jpg Conduit and trunking This picture shows how the electrical conduit and trunking installation should be coordinated with water pipes on the building. Trade subcontractors (water piping sub-contractors, electrical sub-contractors, telephone cabling contractor, computer network contractor and others) must not be allowed to proceed with the installation of their individual services and equipment on the first come, first served basis. Prior to the commencement of the installation works by trade sub-contractors, a set of proper coordinated drawings, endorsed by all relevant parties, should be made available to all the sub-contractors involved in a particular area. https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEi29qZ3FH7l562iRquGRl7AjfsfkXS6WRfg8CVo-E3XsoovyrP8VfZ-m4gA9h3URLOQQHgwTo2OJ-zj1uSVUqI8GVi6cC0jXylcfr936frKXRG9uY4KwbleJx7TksgdIGhA3AY19wscmLiU/s320/Below+Slab+Trunking+Installation+Photo.jpg Electric trunking running below soffit of a concrete floor slab There is no electrical installation work of a significant size can be done properly without the use of an electric trunking. A trunking is a larger size of a conduit. When you need to run a number of electric conduits along each other for a significant distance, then consider using a trunking in place of the conduits. There are so many sizes you can choose from. The above picture is an example of a trunking installation above ceiling level, under the soffit of the concrete floor slab. we also labeled some of the other services there for the benefit of those non-electrical readers who need pictures like this for reference, to know what is what among the myriads of pipes, conduits and trunking running above the ceiling level. https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEgH4hnYdNeJZB5AhSRjMt9AUHXUUu9RUK4woEXRdcor5wqv_661CVRkPIBp0KLzLJoez2lkKlU7xR8vsIcVpTu_dt5evnOCRiBejw2PNQOCNjr6zjEuZVjGkxOktwBIHOJrzL9c287oug8D/s320/Wiring+Trunking+Picture.jpg Electrical trunking in and out of the electric panels There are electrical trunking connecting the panels at above and below the panels. But the box-up walls have hid them. This picture is metal trunking. In future, the maintenance electrician would need to access and open the cover of the trunking in the repair and upgrading works. Therefore, a means of access is required, which was not provided at all at the mock-up unit. https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhthoYNNwKrxqEQWgOZnQlTS-vTpUuRocYY3dk7ehW2dNUPinS6xaBQS639u79Jnu57nyV-MKfCJWpbuaQaizMDWama3sxaP2PrKzvdvdnW0L6ArNgffYwT5Lnf7JZJ_XroUoK3fTJUfLhM/s320/Underfloor+Trunking+Installation+Photo.jpg Under floor trunking installation The under floor trunking system has been around for a long time. An under floor trunking system is an alternative way of providing the dedicated routes to run electrical cables, telephone cables or any other wiring cables. An 11KV cable is not a wiring cable. A 25 sq.mm electrical feeder cable to supply an 11 KW fire pump panel is not a wiring cable. The 1.5 sq.mm cables that are used for wiring the office lights are categorized wiring cables. https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEh-lL3ysX5r00bPNJSNcADyWi6wfkSfmhgJYtgsbyZWrdkR-KmWQUVWCI2TsOJ0aFzBlW46Y5BI9Dtim3Q2BuwubwM6f51wNp6RkoLRDLFM6lZp6iStyZqAWejysi9boeniChXC1iQYv4N7/s320/Surface+Conduit+Installation+Picture.jpg Surface conduits The conduits are used to protect the wiring cables that carry the electrical current. Electricity is dangerous. Even though the electric conductors that carry the current is insulated by some PVC covering materials or whatever, the covering material is not strong enough to protect the cable from damage. When the covering is damaged, the electrical conductor inside may be exposed to touch or it can also unintentionally come into contact with things that can carry electric current. This scenario would present a high risk of electric shocks. Therefore, we protect the electric cables so that they do not present the dangers of electric shocks to people (or animals). A second reason to protect the cables is to make sure the electrical system stays reliable. When the cable PVC covering is damaged, the conducting metal can come into contact with other metals that are in contact with earth. https://blogger.googleusercontent.com/img/b/R29vZ2xl/AVvXsEhXvquIbsllwTPrqvZ-5d-a-bjt-_d0PIvLxOo1IOOrXCnIO0MZwcCIB_v-i3emgSjKh5_pC1Nv1J6BsvspveRT1LPa84nhrO3cKQLrEZDzGuqHgOBNMtQdiUTobbu8es7KwaG1Cfrq71L7/s320/Overhead+Projector+Installation+Picture.jpg A motorized overhead projector The electrical contractor produced a mock-up unit of the installation bracket for motorized overhead projector.
