ELECTRIC CART PERFORMANCE ANALYSIS Assignment Example | Topics and Well Written Essays - 1250 words

ELECTRIC CART PERFORMANCE ANALYSIS - Assignment Example These motors are powered with the help of battery packs, which are rechargeable. Electric motor offers several benefits compared to the use of internal engine combustion to power vehicles. These include zero emissions of air pollutants, fuel economy among several other benefits. Electric motors enhance the performance and greater efficiency of energy. The general costs used in maintaining and operating electric motor powered vehicles are low compared to the conventional fuel driven vehicles. Selecting as well as calculating the correct motor for the electric cart vehicle depends largely on the total weight of the vehicle, the area where the Cart will be used and the terrain of the area. If the Cart is to be used in a hilly or an area with mountains, the individual will require more engine horsepower than in a flat terrain. The speed of the motor is also dictated by the aerodynamics profile of the Cart before and after the conversion and its use. A simple cart used for commuting in a normal city traffic definitely requires a cheaper motor with less horsepower compared to the one to be used in winning races or have the fastest acceleration. Several other variables can be used in calculating the speed of an electric motor depending with its use (Chi-lan et al. 2011). The speed of an electric motor and vehicle largely depends on the battery pack voltage. Using a Direct Current (DC) motor, one hundred and forty-four (144) volts will be enough to drive the vehicle at a speed of seventy miles per hour. The available power that is stored in the batteries determines the total distance that the cart is able to go before recharging it. Power measured by calculating the voltage in the battery multiplied by the battery amperage multiplied again by the useful power that is available in the battery without damaging the cells. The chemistry of the battery is the one determining this figure. This does not indicate

Wartime Stories Essay Example for Free

Wartime Stories Essay While there are few that claim war is one of the greatest institutions of humanity, it is certainly one of the most discussed, more recalled, and most participated in creations civilization has yet conceived. The lessons that can be learned from wars vary greatly in ethical and moral implications, from those that say war must be participated in with ruthless precision, while some feel that war must be fought with decency and honor. Whether to sacrifice one’s own life for a greater good, or to fight merely to preserve one’s life at all costs is a question of utility value versus ethical egoism. Movies such as Saving Private Ryan present interesting ethical dilemmas concerning a soldier’s internal and external ethical duty during war. While the men are charged with possibly giving their own lives for the life of only one other soldier, they are torn between the duty to their country and their orders, and their dissatisfaction over having to devalue their own existence for that of someone they do not even know. They feel a greater duty to each other, as well as the war effort in general, but feel their mission to save Private Ryan falls outside their duty, and effects little their honor. However, the movie persists in continuously asking the question of wartime ethics. The question for the men is whether their life is worth that of Ryan’s, merely one soldier among the millions. The order they have to get Ryan is one of utility value, as dictated by the rules of service. It is a soldier’s duty to follow orders, no matter how much they may disagree. If soldiers began disobeying orders it could spread and eventually break down the entire system. The obligation that Captain Miller feels in the movie is that the successful fulfillment of his orders will not only continue to hold loyal to the chain of command, but will also bring his unit one step closer to going home. However, when finding Ryan, the situation changes as Ryan refuses to come with him, agreeing that his life is worth only the value of those men with which he fights. Still following his orders, Captain Miller does everything in his power to save Ryan, still fight the war, and keep alive the chain of command, never once letting his own desire to go home influence his loyalty to his orders. The soldiers in the movie spend the majority debating the value of saving Private Ryan as opposed to fighting the war and trying to win it. They feel that they are on a mission that unduly puts their lives on the line for little purpose, as they value their lives far more than Ryan’s life. Their individual egoism would seem to oppose the entire concept of being a soldier in the military, as the chain of command is dependent upon groups of individuals functioning as a single unit. Even as a single unit, they are forced to abandon their individualistic ideals, as the unit is in as much danger as each individual. In the end, most of the men die, save for the most vocally opposed soldier, the most inexperienced and cowardly, and Private Ryan. The men fulfilled their orders, but paid with their lives, as they feared they would. The death of the soldiers, including Captain Miller, seems to suggest that in sacrifice lays honor, at least in war. The soldiers all recognized the mission as wrong and dangerous, but their duty as soldiers required them to fulfill it. On the one hand, the mission was fulfilled, but on the other hand they all died. The utility value of their sacrifice saw that not only was Ryan saved, but the important bridge was held, and they did in fact fight a very important part of the war, as well as a less important but far more â€Å"decent† part. The fact that Captain Miller is killed by a German soldier that he previously released rather than killed also seems to suggest that decency in war is often rewarded with death, as he and most of his soldiers exemplify. The senselessness of war and the mass violence of modern warfare would almost suggest that loyalty and duty to anything but oneself is a fool’s errand, but it also suggests that by fighting for the best attributes of humanity, like altruism and sacrifice, the entire human race takes a step closer to a civilization free of things like war.

The Potential Of Wind Assisted Ship Propulsion Engineering Essay

The Potential Of Wind Assisted Ship Propulsion Engineering Essay Wind is present all around the world, and in some places with abundant energy density. Wind had been extensively used in the past, for mechanical power in addition to transportation (J.F. Manwell and J.G. McGowan, A.L. Rogers (2009)).Wind energy has evolved into one of the most practical, cost-effective and both environmentally and technically attractive, of all the renewable energy options in the world. So the wind energy has a lot of potential at sea for assisting in ships propulsion. Wind is the cheapest, most powerful, and greenest source of energy on the high seas. The accelerating fuel costs over the last decade have led to growing interest in the application of wind assistance for ship propulsion and reduce fossil fuel consumption. Using wind energy for propulsion of ships in sea is in fact one of mankinds oldest ocean-going technologies. In one-way or another, with modern advances in ship design and propulsion the use of wind energy was almost forgotten Sail systems were the dominant form of propulsion until the 19th century (http://en.wikipedia.org/wiki/Marine_propulsion) Astrophysicist Carl again writes, for example, that: the consequences of scientific illiteracy are far more dangerous in our time than in any that has come before. Its perilous and foolhardy for the average citizen to remain ignorant about global warming, say, or ozone depletion, air pollution, toxic and radioactive wastes, acid rain, topsoil erosion, tropical deforestation, exponential growthà ¢Ã¢â€š ¬Ã‚ ¦.How can we affect national policyà ¢Ã¢â€š ¬Ã‚ ¦ if we dont under stand the underlying issues? Aim and Objectives: The main of the project is to analysis into the potential of Wind Assisted Ship Propulsion (WASP) and its application into the modern day shipping. WASP systems will be explained, analysed by showing its benefits and drawbacks. The applications and possible benefits of the use of the WASP will also be investigated showing all the relevant factors that are affected by the use of WASP. The key objectives are summarized as: Research into present and evolution of WASP systems, Potential of present WASP system and their applications. Advantages and future development of WASP systems Discussion of economic and environmental factors Analysis into the use of alternative energy sources at sea. Evaluation of WASP by application to a case study Critical analyse into all findings to produce a logical and well founded conclusion. EXISTING WASP SYSTEMS: The following are the remaining WASP Systems in use at present in the sea Aerofoil(Wing-Sail) Flettner Rotor Rig Soft Sail Towing Kites (Skysails) Wind Turbine (Skysails) Aerofoil (Wing-Sail): This form of marine propulsion works in the similar way as an aeroplane wing, producing pressure differences between opposite sides which create a force , supported by central mast. The trust provided by the solid structures of the sail is more with less drag than conventional sails. This technology came into wide development in 1980s by Japanese and still some vessels use this technology nowadays with research into the application of such systems proceeding. Various research is been carried out and one of the example using this aerofoil concept is this ship model which is called the ecoliner. It is a type of cargo vessel which propels by using combination of high-tech sail and engine power. This combined feature, make it possible to work like a normal cargo ship with similar service of speed, freight price and other factors. Using this ecoliners , as ocean transports will decrease the pollution emissions to 50% of the ship. MV Ashington vessel is a bulk carrier which has auxiliary propulsion with the use aerodynamic wing sail. (http://www.shipspotting.com/gallery/photo.php?lid=823976) A computer controlled wingsail fitted to the 6,500 dwt dry cargo ship mv Ashington resulted in a fuel savings average of 8% and, under favourable circumstances, of up to 20%. (htt p://www.maritimejournal.com/features101/power-and-propulsion/wingsail_ready_for_small_commercial_vessels) The wing-sail have two significant drawbacks which are considered. First one is that the moments coupled with the lift forces which produce the propulsion also can create a large aerodynamic drag force which acts as a huge drawback when sailing directly into a head wind(Clayton, 1987).Rigid sails then usually themselves into the wind direction when no force can be created while some design allow the surface to be folded using hydraulic controls such that the direction can be controlled. In general wing-sails have a high lift coefficient compared to soft sails which will be discussed in further topics. This means this system has more advantage over the other conventional sails even though initial investment in the system will be high. Various designs now incorporate a frame with a material surface to keep the minimum weight. Flettner Rotor Rig: Flettner rotors consist of cylinders which are of spinning type and tall mounted onto the vessels deck. The vessel is set in motion by using the Magnus effect. The Magnus effect is produced whenever pressure difference occurring around spinning object. This concept was done by researcher Anton Flettner, a German naval architect. Later researchers conducted experimenting into its operation in 1980 when Saudi oil crisis happened. But this system never overtook the diesel engine usage. However in the 1920s Fletner rotor operated in sea for a quiet a long year proving reliable form of wind propulsion. To understand this system works, an understanding of the Magnus effect is necessary. The Magnus effect or force happens when there is a pressure difference around a spinning object. Because of this change in boundary later around this object happens, a lift force is generated in direct propulsion to the acceleration it imparts on the air streaming by (Seufert, 1983). This lift force happens due to Bernoullis principle; this use of the principle is highly effective and is described as practicable. Soft Sail: Soft Sail system consists of two main types, the modern square rig and the fore and aft rig. The square rig is the most efficient running rig and useful to longer routes with more constant and foreseeable winds.Fore and aft rig type is suitable to short routes, where the wind speed and direction be unlike. In modern day shipping the soft sails is not used, because of its large propulsion of deck space and needs constant manning. The reason for this is because the other types of sailing systems are more effective and efficient compared to these soft sails. The sky sail lakes large portion of deck space and always need constant manning. With deck space is considered more important for carrying cargos in present shipping world, it makes less effective in use and outweighs the advantages of any soft sail systems. The future of ship propulsion may consider this soft sail with combining with other types of propulsion to take advantages and use it in a efficient way. However there are some smaller vessels like fishing boats still depend on soft sails as an auxiliary propulsion force and the uses of soft sail are important in this fishing boats Towing Kites (Skysails): Towing Kites function on same basis as several conventional kite arrangements used on such things as Paragliding and kite boarding, etc. the propulsion of the vessel is assisted by the kite which harness the energy from wind. Since wind-conditions are not always sufficient, the Skysails system is designed to function as a supplementary power source, in addition to the ships engine. Skysail consists of a towing kite, a control system, a launch and recovery system and a wind-optimized routing system. The Para foil kite is constructed out of  high-strength, weatherproof textiles, and  is designed in such a way that it can achieve optimal aerodynamic efficiency at any wind speed. The steering system operates automatically and is composed of the control pod and the control system. The towing kite and the towing rope are linked by the control pod. Much like autopilot systems in airplanes, the Skysails sensors collect data that is processed by the systems software, which sends control orders accordingly. The launch and recovery system is responsible for automatically recovering and launching  the towing kite, control pod and towing rope. The kite is attached at only one point to the launch and recovery mast, enabling high manoeuvrability. A telescopic mast lifts the towing kite  during its launch. The wind unfolds the kite to its full size while the reef system launches the reef ropes. While the towing kite is decoupled from the launch and recovery mast, the towing rope is released. The power transmission system consists of a  towing rope, a force transmission point (tow point), and winch, and is responsible for transferring the tractive force from the kite to the ship.  The mounting system ensures that the towing kites force is aligned ideally to suit the winds direction. The routing system is composed of  a weather forecasting performance calculator, which processes the weather forecasting data and of a decision-making model, which calculates the optimal route following priorities set by the ships owner. Finally, the routing system has a route recommendation feature, which translates the information into a series of waypoints read by the shipmaster. The SkySails system also improves the ships safety and performance on water as it damps the waves so that the ship suffers from less slamming and torsion forces. In addition, as a result of smoother sailing, the ships life is extended. A short video of a ship equipped with the SkySails system is available (http://www.maplesoft.com/company/casestudies/skysails.aspx) The steering system of skysail operates automatically meaning that there is no input need via crew, just observation. The skysail system will have a control pod situated on the high strength towing rope and the kite. This pod changes the profile of the kite such that it ultimately controls its flyting path in line with ship needed direction. Wind-Turbine: Wind turbines are widely used in land; however it has not yet been applied on at large scale in the shipping industry. Wind turbines at sea could perform two functions as electricity generation and in aid of propulsion. The drawback using wind turbine is it will be ineffective at no wind and counterproductive at high wind conditions.many smaller vessels have used wind turbines directly connected through gearbox to the propeller. But large vessels need large size machine to drive the generators which makes complex engineering to make it work stable. Also this system will need more time to get fitted, assembled such that it means it will be suitable for future vessels. APPLICATION OF WASP SYSTEMS: The use and development of WASP systems in the modern day shipping should be considered to make an adequate conclusion .At present WASP system are at very small percentage of the global marine transportation industry. The different types of systems are already present in use various ships and also in small vessels such that it makes easy to have a very good potential in upcoming years since the price of fossil fuels hikes and also they pollute the air which made global impact to cut the harmful exists of these pollution.by looking at the advantages and the usefulness of WASP systems and its drawbacks, various factors related to it can be analysed. The further topics will discuss about the advantages and applications of these systems. POTENTIAL OF PRESENT WASP IN PLACE: WASP is already in place for long ago in small vessels like boats in fishing industry. Currently WASP is present in less in global marine industry but its still considered as notable, potential system to avoid fossil fuels.by analysis the various factors and cases, understanding can be done greater. Oil crisis happened in 1970s and 1980s , the Japanese were very conscious and tried to look into alternative to the field of ship propulsion and some 17 sail- assisted tankers were produced with all having similar design. The first vessel with name Shin-Aitoku-Maru (DWT: 1600), in 1980 reached 11knots speed when the sea and ship conditions were good. These sails travelled in sea during that oil crisis but later the oil prices dropped down again .this made the diesel engines to overcome those sails and the marine industry discarded to use the systems .however the environmental concern arrived in 2010 regarding water and air pollution due to the fossil fuel .this play a massive role to change the world to look into alternative energy sources that can be used in sea and imposing rules and regulations on various pollution factors. APPLICATION OF WASP: The application of WASP systems are vastly used in fishing industry in smaller vessels. Many American and European boats have small auxiliary soft sails but they are used rarely. Large commercial fishing vessels does not utilise wind at all, since it would be impractical most often. They increase work load on crew with others factors including cost of the equipment and less knowledge to use the system of WASP will make it difficult to use it. It can be seen in statistics that WASP could be used in fishing fleet to a greater extent that actually works. By looking at historical research, wind has been used ad earlier way of propulsion when no engines exists. The transaction from the main form of propulsion changing from wing to coal- fire propulsion units took place so quick over a time spam of 30 years. However increase in price of fuel and pressure to reduce fuel consumption. Skysails are used by Wesselss Sipping Company on three vessels where some good results have ben obtained. WHERE WASP MAY BE APPLIED: Although climate change has occurred since the creation of the Earth today it represents a setback to a society that grew in the last two centuries to over 7 billion with an associated energy demand based primarily on the consumption of fossil fuels. The global population is expected to peak at 9.2 billion around 2075, while social development is desired to continue.so its important that WASP could be used in various ships propulsion. WASP may not be a good solution in making all vessels more efficient and reduce fuel consumption. But some vessels use the benefit of this systems.in recent years Ultra Large Crude Carriers (ULC) and Very Large Crude Carriers (VLC) dominates the transport of crude oil and the benefits of WASP on such kind of carriers are hard to be seen in practice. But smaller carriers may benefit from WASP technology and vessels which run on lower speed can use this type of propulsion to reduce fuel consumption. For example, steam coal and iron ore are usually stored on a very large scale before the resource is even utilised. In that case the vessels can carry them with the use of WASP which can produce 11-13 knots speed and its practicable. FACTORS One of the weapons used by all vessels, the WASP combat is essentially highly advanced missiles that contain a variety of sub munitions. The computer that controls each one is also able to analyse tactical situations and plot the best path to achieve your goal and ensure success. The WASP has a maximum acceleration of 20g when using standard fusion fuel. This acceleration and speeds allows the WASP conditions for manoeuvre and more power. This speed advantage and acceleration allows you to run more. In addition to attacking enemy ships or space stations, WASP combat can also be used as a defines drones. In this mission profile, WASP can also be used as thermonuclear warheads or anti-matter ahead of the enemy. The health and economic impacts In this area, we are only beginning to understand the true extent of the consequences on utilization of WASP systems. Intuitively there is an accumulation of pollutants through the food chain and possibly in our drinking water supplies. But, according to Technical Document Management Measures National Pollution Control Environmental Protection Agencies, published in November 2001, petrol, oil, diesel fuel, and batteries and acidic cleaning compounds, and solvents involved in the maintenance of the boats ( as methylene chloride, tetrachloroethene, trichloroethene, and trichlorethylene) trickle in lakes, rivers and coastal areas, and many of these pollutants, particularly some of the heavy metals are attached to sediments and are eventually found in the food chain through either plankton or other organisms and then concentrated through the food chain, being a major environmental threat as well as a big human health problem when it comes to fish consumption. The high speed of supply and refuelling system used by WASP does not mask the problems caused by liquid spills and toxic gases; rather, it completely solves the problems. Industry There are economic consequences for the marine industry. The short-term impacts that cause direct financial costs are cleaning and punitive actions associated with them. Over time, the waters are much polluted, further legislative measures are introduced. Clean water is essential for multibillion dollar industry. Environment Supply system by WASP system is a high-speed refilling helps the environment in many respects, eliminating damage caused by other products refuelling. This product eliminates the smoke harmful gas that gives off the oil, polluting the air. It eliminates the greenhouse gases that pollute the earth and our ozone layer. This system prevents leaks that harm the soil. There was never a supply system created before can eliminate all kinds of damage, and that works without causing pollution. The high speed of supply and refuelling system using the WASP does not mask the problems caused by liquid spills and toxic gases, however, solve them by complete. Most of the damage caused by the emission engines and oil leaks comes from petroleum. Small leaks, despite being isolated events tend to occur every day around the world, they are, gallons of oil pollution in our waters. A small fuel leak affects a disproportionate amount of water on the surface of the ocean. In the UK the legal limit leaking oil and one drop of oil for every 2 litres of water in a proportion of 15mg per litre. Therefore, a single litre of oil can contaminate one million litres of water. And this is a chronic problem to be solved, and the reaction of sunlight, the chemicals become infinitely more toxic, and prolonged exposure affects thousands of fish species and a myriad of creatures such as shellfish, marine plants and damage as algae and their reproduction when exposed to oil. And the old trick of using soap or detergents to make the brightness disappear, is not only illegal, but it only makes pollution worse, and eventually adding surfactants to the mixture, whic h attach to the gills of fish and destroy their ability to breathe. The effect is catastrophic. And, as if that were not enough, the increase in population drives the development of the industry, and a lot of pressure on the marine environment. The impact on marine life inevitably leads to an impact on human health. WASP Systems are specialized in projects for supply, installation and commissioning of water systems and wastewater treatment systems, gray water recycling, along with some simple write-downs and innovative energy systems. The system creates a vacuum seal ventilating, and dramatically reduces the incidence of unintended leakage of gas that would normally escape to the atmosphere. The main advantage of the invention is that it allows the filling very quickly, which will significantly reduce operating costs for operators of vessels and facilities loading terminals. Applications for the WASP system will focus initially on three distinct segments in the market within the maritime industry: nautical recreation, navigation and commercial refuelling (as tugs, barges, ferries and commercial vessels), and loading of liquid cargo from ships that cross oceans. The deployment of this system in the world will eliminate millions of tons of harmful particles of gas to the atmosphere, and prevent millions of gallons of fuel from spreading into watercourses .freighters with this product, which is able to increase the delivery time cargo 100% and thus may reduce the time spent in each vessel terminals. We can shorten the terminal for vessels which reduces the rate per ton of whole load of liquid therefore increase the amount of deliveries for all vessels. We can reduce the waiting time for vessels which reduces the rate per ton of whole load of liquid therefore increase the amount of deliveries to all ships refuelling and increased how it works at high speeds. Our product also eliminates many greenhouse gases and gases hazardous to health that are associated with refuelling which in turn becomes safer for everyone to use our product to refuel. Currently we are working together this time with a major oil company and help them in their oils movement worldwide. 6.2 Economic factors Economic factors in the application of WASP freighters These ships can perform rapid sustained combat operations at sea as a centrepiece strategy. To carry out its core mission, WASP has a support system that synchronizes the simultaneous horizontal and vertical flow of cargo and vehicles throughout the ship. The ship propulsion can generate a total of 400 tons of steam per hour. If the energy of the two boilers were converted into electrical current could power a city of 160,000 inhabitants. Electric generators aboard a ship can provide more than 16,000 kilowatts of energy. Two stations provide a capacity of 450,000 litres to 200,000 litres of water per day supply. Chapter 5: Case Study 5.1: MS Beluga Skysails MS Beluga Skysails with its computer-controlled kite (top right corner) One of the latest innovations in the heavy cargo ship which increases fuel prices has been a return to wind power. The MS Beluga SkySails is a heavy carrier that uses a towing kite system as part of its propulsion systems. The ship was launched and followed early sea trials in the North Sea in January 2008, the vessel embarked on its maiden voyage from Bremerhaven, Columbuskaje to Guanta, Venezuela. On route, the efficiency of the system was applicable in winds of up to force five for 8 hours a day. The system was hailed as a success, with calculated savings of up to 2.5t of fuel/$1,000 a day. With larger sails of 600m ², fuel savings can get up to 35%, possible. CONSTRUCTION The system has been developed by SkySails SkySails GmbH and Co. KG. The Beluga SkySails was equipped to navigate with a candle paraglider 160m  ². The area of à ¢Ã¢â€š ¬Ã¢â‚¬ ¹Ãƒ ¢Ã¢â€š ¬Ã¢â‚¬ ¹the kite can be increased to 320m ². A pipe controlled by computer, is connected to the ship by a system of rope. The system can control the kite at altitudes between 100m and 500m to maximize the benefit of the wind. With oil prices so high, a cargo ship 87m average could save about à ¢Ã¢â‚¬Å¡Ã‚ ¬ 300,000 a year. The system can potentially be adjusted to any ship. The overall reduction of carbon dioxide transport arrives at an estimate of considerable million tons per year. The BBC said there is something magical, a giant cargo ship being pulled on its way to the sea with ten thousand tons of metal, and with the sun shining giant masts. But there is something even more magical about the MS Beluga SkySails. On the face of it, this ship leading, for example, parts of a production line of wood to Venezuela looks like any other cargo ship. MS Beluga SkySails believes its fuel bill will be cut by  £ 800 ($ 1,560) a day. We can demonstrate that it is possible to combine economy and ecology, says Verena Frank of Beluga Shipping, and explains, Economy, because you can reduce consumption and fuel costs and, moreover, contribute to ecology, reducing emissions carbon dioxide. the kite is controlled by computers. a computer helps to make it fly, and maximize the power it produces, the other computer adjusts the direction of the kite. If the project is successful, we expect to see kites even higher very soon sum up to 5,000 square feet in size, pulling ships ac ross the seas and oceans. Graphic Steve Rosenberg explains, See how the ship kite works: of all the CO2 that is pumped into the atmosphere today, 4% comes from ships. Thats more than the aviation industry, mainly because 90% of world trade is done by sea. The MS Beluga SkySails believes it has the solution environmentally, with a mission to transform the green oceans. Once the ship reaches the open sea, reveals a new weapon in the fight against global warming: a kite. The 160m2 kite is hoisted on a mast and for half an hour or so, he stands there at the top of the mast, not making a big thing. The wind and certainly a wonderful thing, because it only needs a bit of wind to make everything else work. Half an hour later, however, the wind makes the kite start to fly hundreds of feet in the air and helping to pull the ship. The paragliding and synonym of power to the engines of the ship, so you can work on reduced power: which means less carbon emissions. It also means lower bills in fuel costs. With the price of trans portation fuel that has doubled in the past two years, paragliding promises great savings. How the Ship-Parrot The kite helps reduce annual fuel costs 10-35%. Fuel economy also means fewer carbon emissions harmful to the atmosphere. The large towing kite resembles a glider and is shaped like an airplane wing, so you can take advantage of different wind directions. The kite operates at 100-300m above the surface much larger than a normal sailing boat where winds are stronger and more stable. The kite can be used in winds of 12-74 km / h (or 7 to 40 knots).

Use of Symbolism in The Rime of the Ancient Mariner Essay -- Samuel Ta

Samuel Taylor Coleridge’s use of symbolism in The Rime of the Ancient Mariner lends the work to adults as a complex web of representation, rather than a simple story about a sailor. The author uses the story of a sailor and his adventures to reveal aspects of life. This tale follows the Mariner and his crew as they travel between the equator and the South Pole, and then back to England. Without the symbols, The Rime of the Ancient Mariner would be simply a poem about an old mariner who is telling a story about killing a bird to a guest at a wedding. Of course, anyone who reads the poem can see that there is more to it than just a simple telling of a story. The first symbol in the poem is the wedding that the guest and the Mariner are at. This is a highly significant detail, because Coleridge could have made the story telling take place at any setting, but he chose a wedding. The reason for this was because a wedding is a very religious and very happy occasion. Weddings symbolize new beginnings and happiness. The reason that Coleridge decided to have this horrid tale told at a wedding could be for any number of reasons. I feel that the setting was chosen because of the new beginnings implied. As the Mariner tells his tale, the guest is held captive and when the story is done, the guest becomes essentially a new man and goes off to live the rest of his life. Had the tale taken place at a funeral, the heavy feeling of ending would have destroyed the symbolism of new beginnings. It could have been an ending for life, for happiness, and for everything else. If this had happened, then the fact that he rose the next day would not have been as significant. Therefore, the wedding is a very important symbol for this poem. Another significant symbol throughout the poem is the albatross. It first appears in the first section and it is a symbol of good omen for the sailors. The albatross is a white bird, which is probably the reason why many Christians of the time saw it as a holy symbol. Because it was a white bird, which was a sign of righteousness, it therefore was considered a good omen. In this poem, the albatross symbolizes good fortune. When the Mariner kills the albatross, for absolutely no reason, the good fortune that has come upon the ship leaves. Symbolically, the Mariner did not kill a simple seabird, but instead an omen of good fortune, which is why... ...riner took a gamble with his religion, and now the pair is taking a gamble for his life. Life-In-Death ultimately wins over Death in the game, and the Mariner’s shipmates die at his feet, yet he lives on. The Rime of the Ancient Mariner is a highly significant poem of a complex web of representation that is very dependent on symbolism. The symbols of the wedding, the albatross, the blood that the Mariner sucks in order to announce the ship and the game between Death and Life-In-Death are only a few of the symbols that add meaning and depth to the poem. If it were not for the symbols, the poem would simply be the story of a Mariner telling his tale to a wedding guest, and then the poem would have no meaning to anyone. When reading this poem, the reader can feel much like the wedding guest, entranced and hypnotized by the storyteller. This is because of the symbolism exhibited through the poem. Even if the reader of the poem does not fully understand the symbols in the verse, the intuitive mind will catch them and understand the detailed meaning. The symbols themselves in The Rime of the Ancient Mariner are therefore the part of the poem that makes it so intense and interesting.

Pleasantville Essay -- TV Shows Pleasantville Essays

Pleasantville If you think about it, today’s world is not such what we call â€Å"user-friendly† place. Unemployment, severe diseases, global droughts and other dreadful natural disasters that are about to happen to our lives. Even better, the more time passes, the more chances you get to face them in the future. But what the heck, everyone will eventually face all of those problems one day. Danger, devotion, abomination, curiosity, and alterations are always present in our lives. You might think that Pleasantville is pleasant. Well do I have some news for you: nope. The name â€Å"Pleasantville† is just a simple irony that’s all. In Pleasantville, everyone is so empty in their minds. For instance, every character always did the same thing over and over. It’s like everything falls into the right way that it should be. The basketball players always score, the wives are always cooking and taking good care of the husbands and children. Husbands are working, children are little precious angels who never get in any kind of trouble. No worries, no problems, just plain good stability. There is no wrong for them because everything was in sync. It would be really tough to adjust to that kind environment where everything becomes dull and unbearable. No color, no fire, nothing exciting except the way Bud made every shot to the basket without even trying to. No changes what’s so ever. As soon as the characters saw changes, everything was getting completely different....

The Regency Hotel management aimed at developing motivation among employees. However the employees were not motivated. Increased fru stration, stress, Job dissatisfaction and high turnover were some of the factors that immemorial employees. Encouraging innovativeness and creativity among employees is an essential component of a successful organization. The free environment provided by the organization was not effectively utilized by the employees.The performance of the organization depreciated as a result. Motivated staff Improved performance of organization Empowerment Empowerment refers to increasing the spiritual, political, social or economic strength of the individuals. It often involves the empowerment developing confidence in their capacities. In some situations empowerment could motivate employees. The problem n the hotel is the measurement of a major or a minor issue. There is not a definition or standard states what a major issue is. Actually employee needs to know what he/ she can touch and what he/she cannot.Conflict comes when the management disagrees with the employees' view.

What the front-counter boy has done may annoy the front-counter manager. Issues ; Consequences After Empowerment Empowerment can be described as People having the skills and the self-belief to proactively deal with issues and make the most of the opportunities available to them. UT soon after the execution of empowerment Becker realism that things are not going according to his expectation because staff of regency grant don't know what is empowerment? Because they use to work as per their manager order in the previous management they are not allowed to innovate & generate anything new ,Ana were Electorates Day teen sensor managers Ana rater all tens teen note want o take risk and get punished by the management but general manger back in America was working in a empowered environment where staff has a power of decision making & can take minor decision on their own . Classically it's a cultural difference between management and staff, where people+ from Thailand believe in team work and management is from America who believes in individuality they believe that they can do anything unaccompanied which was the first issue. Outcomes Of The Failure Of Empowerment Due to failure of empowerment hotel regency grand was losing its profit, client's and tutus in Bangkok as well as it's intangible assets like market value and quality standards began to decline.Becker thought that empowerment will help his hotel to earn more profit and guest satisfaction but his strategies backfired on the hotel reputation, resulting in the decline of the overall Performance of the hotel. It was for the first time that there were an increase in number of guest complaints both verbally and in written. Guest started complaining about the services provided to them and above all disgrace in the news paper as one of the Sais's nightmare hotel. Criticism about service standards of the hotel, Staffs were also not happy takes it to the inequity among the employees.Back biting among employees was commonly seen now and good working atmosphere was harshly strained. Lack of team spirits among the employees now they were against each other when mistakes were made by any employee. Unclear power hierarchy Unclear power hierarchy Another major issue encountered at the Regency Grand Hotel which affected the organizational culture was the problem of unclear power hierarchies which lead to staff not understanding their role clearly in the decision making process. Employees were given empowerment but this proved to be problematic as staff were unable to discern between what constituted a major or minor problem.Staff found that in many cases when they did make a decision it was later overturned by supervisors. One part of the process of empowe rment is impact. â€Å"Empowered employees view themselves as active participants in the organization; that is, their decisions and actions have an influence on the company's success† (Ms Shame, 2008, p. 185). Becker introduced empowerment but this part of the process was distorted as the employees felt that their decisions were not valued and often overturned. Additionally, Becker stated he would not tolerate the same mistake twice.Staff now found it easier to revert back to their old ways of passing all problems over to their supervisors. This was directly counteractive to the plan of â€Å"allocating more decision-making authority to front line employees† (Machines, 2008, p. 192). This further reduced the effect of empowerment. Job Design and Role Ambiguity Job Design and Role Ambiguity Employees were uncertain of the types of issues that were to be considered â€Å"Minor† and â€Å"Major†. Without clarification, they continued to refer problems to man agement.Jobs that have ambiguous demands, Jobs that have too many demands, and Jobs that do not allow the employee to participate in work related echelons are Kelly to anneal attempts at stressful performance, tenured frustrating higher order needs† (Behr, Walsh ; Table, 1976, 42). This frustration results in reduced effort and motivation. They go further to state that â€Å"Effort toward quality is related to role ambiguity in that concern with the quality of one's work is not maintained if it is unclear what constitutes task success†(Behr et al, 1974, 46).Supervisors were unsure and reversed employee decisions to refer them on to higher evils of management. Role Conflict: The front-line staff were expected to experiment and be creative in dealing with situations at work, but were only allowed to make a mistake once. This resulted in reduced learning capacity as employees began behaving defensively in order to avoid reprimands for errors. Reduced Job Satisfaction: Incr ease in customer complaints, increase in absenteeism and employee turnover. Intra-organizational relationships suffered as trust was lost and fear reigned.Poor reviews due to declining levels of customer service. Role Ambiguity Role ambiguity Role ambiguity was another issue for the Hotel. Role ambiguity can be defined as a lack of information needed to perform the role (Pearce, 1981; Cooper et al. , 2001). This issue can lead to many problems. â€Å"Employees who experience role ambiguity tend to perform at lower levels than employees who have a clear understanding of Job requirements and what is expected of them. Likewise, role ambiguity is reflected in employees' uncertainty concerning appropriate actions in commonly occurring Job situations.It explicitly results when employees are not clear concerning the amount of authority they have and when they do not know others' Job reference expectations Job design According to the Job characteristics model, employees are more motivated and satisfied when Jobs have higher levels of characteristics. People have different skills, it is important to put the right person into the right position. A few employees of the hotel were transferred to other positions when the acquisition was done.They might not have the abilities to complete the full range of the new work. Recommendations Recommendations for introduction into the Regency Grand Hotel In addition to the exercise, relaxation techniques and learning and development solutions, it is commended that Employee Assistance Programs be introduced to the Hotel, this program offers employees a service whereby challenging situations can be discussed with counselors and psychologists who can provide tools that will embed coping mechanisms (Traveler and Protocol, 2005).Recommended stress reducing strategies Physical activities Relaxation techniques Learning and development solutions Employee assistance program O The remedy for the situations that have evolved within the hotel is to clearly define each person's role and make them aware of the importance their part plays in the overall operation of the hotel. Ensure employees are aware AT tenet irresponsibleness Ayatollah to Attlee want Is a major Ana melon problem and make it clear to members of staff who has the power to make decisions at each level, would also be of great assistance.For example if a problem arises at the front counter with a customer which would incur a minimal cost to the organization this could be handled by reception staff with little impact on the supervisor and within a much faster time frame causing less inconvenience to already disgruntled customers. This could be achieved by removal of the ‘same mistake twice rule' that Becker introduced. In this way employees would truly feel empowered to make decisions that would have an impact on the organization thereby feeling that they were an important part in the hierarchy that exists in the hotel.Address Managerial / Supervisory l evel employees' concerns at losing power. Reward them for encouragement and development of front-line team results. Conclusion The majority of problems experienced during the acquisition of the Regency Hotel may have been avoided or at least reduced dramatically through effective communication strategies, incorporating a comprehensive feedback loop to ensure understanding of changes and new requirements on an organizational level as well as individual level for all employees.Cultural, personal and organizational aspects should be taken into account; and changes to Job design and Job roles should be made clear to ensure successful adoption of the new system. At this stage, the Regency hotel is in a state of flux, with reduction in staff retention, profit and reputation. Effective change management strategies as outlined in this presentation should now be introduced to assist the employees to build a new Organizational Culture and incorporate the Empowerment strategy.
