1. In The Matrix, The “Matrix” Is An Idealized World That

1. In The Matrix, the â€Å"matrix† is an idealized world that is essentially a computer simulation which prevents humans from seeing the real world, which is full of many difficult troubles and dangerous situations. The Matrix prevents humans from seeing this truth about the real world and allows for humans to live in a simulated world representative of life in the year 1999. Meanwhile, in The Allegory of the Cave, the cave is a cave where three prisoners have been chained up for their whole lives. These prisoners have their legs and necks chained so that they can only look straight ahead at the cave wall in front of them. There is a fire behind the prisoners so that the prisoners are only able to view the shadows of the movements behind them†¦show more content†¦Morpheus and his crew initially believe that Neo is â€Å"the one† to free mankind from the trappings of the matrix and to expose humans to the real world outside of the matrix. Meanwhile, the escaped prisoner is set free from the cave and is forcefully dragged into the sunlight. Over time, the escaped prisoner adjusts to the brightness of the world outside of the cave and learns that the reality he once believed to be true in regards to the shadows is not actually true. The escaped prisoner eventually believes that life outside of the cave is much more profound than life inside of the cave and wants to bring the other prisoners into the real world. However, the other prisoners do not believe what the escaped prisoner is telling them about the real world as they have never left the cave and do not want to leave the cave. The purposes of Neo and the escaped prisoner are similar because they are set free from the worlds they have lived in their whole lives to discover the truth about the world. Both Neo and the escaped prisoner similarly aspire to bring others into the light about the realities of the worlds they both live in, but face various challenges along the way, in Neo†™s case destructive technology and violence and in the prisoner’s case ignorance and stubbornness. Both characters attempt to use their newly-discovered truths about the realities of their lives to free other characters fromShow MoreRelatedModule Guide For Assessment Hand2718 Words   |  11 PagesLIBRARY WORKBOOK Exercises 1 – 4: Using the Library Catalogue: HAND THESE IN FOR MARKING – See module guide for assessment hand in date Note: Books other than those specifically mentioned may be used to help you to answer some of these questions. 1.

Rhetorical Analysis Of Seabiscuit An American Legend

Rhetorical Devices Examined in Seabiscuit: An American Legend How does a scrawny, bitter, and lazy horse become the champion of 33 races and holder of 13 track records? A heroic symbol to the United States, Seabiscuit was the epitome of how persistence, courage, and dedication are enough to transform an underdog into a victorious winner. During the 1930s, when America was still in the grip of the Great Depression, Seabiscuit managed to capture the nation s imagination and unite the country. With the help of the radio, a novel invention which made live broadcasts viable coast to coast, the country was able to follow the tale of the classic underdog and discover how the little horse with a big heart overcame a career ending injury to win†¦show more content†¦His rags-to-riches career as a bicycle salesman turned automobile dealer and then distributor. It also describes the accidental death of his son in a car accident, the collapse of his first marriage, and the introduction o f horse racing to Tijuana in conjunction with the economic effects of Prohibition. Additionally, the reader learns the the circumstances under which Howard met and married his second wife, Marcela, and the unusual chain of events that encouraged Howard’s involvement in horse racing. Another key figure is Seabiscuit’s trainer, Tom Smith, an old cowboy with an intuitive understanding of horse psychology. Smith, a man of few words but a brilliant trainer of horses, learns to approach each horse as an individual and to tailor training methods. These unorthodox training techniques helped cure Seabiscuit of several of his bad habits, including his reckless behavior towards jockeys. Seabiscuit s primary jockey, John â€Å"Red† Pollard, was an impoverished rider struggling to pursue his financially unstable dreams. So desperate to make money, Pollard outworked himself doing strenuous tasks to make it by. Pollard was even rendered blind in his right eye while exercising a horse for only fifty cents. Visually damaged by a clump of dirt that struck him in the head and plagued by injuries to his shoulder and his leg served as stressors that rendered Pollard

Wireless Charging For Electric Cars-Free-Samples for Students

Question: Discuss about the Batteries and Wireless Charging For Electric Cars. Answer: Introduction Environment and energy have been playing important roles in the electric transportation system. Electric vehicles have high flexibility and charging is not easy for them. EVs keep high battery backup as storage for electricity to operate in a long distance. As stated by Vaka and Keshri (2017), the wireless power transfer can alienate charging system and its battery capacity is less than the storage system. Importance An internal combustion engine can run swiftly in case of a long way, however, EV needs high power battery efficiency. This high power battery can be expensive for use; however wireless charging system can be cost effective for energy use and gasoline-powered vehicles. Battery needs a charging system and plug-in methods, wireless charging can be beneficial for this. Charging cables can also bring hazards, however, in WPT, drivers just need to park their cars near a charging station and dynamic WPT will charge the cars (Li and Mi 2015). This wireless battery charging provides 20%more battery back-up than conductive charging. Of late, the wireless charging generates high demand in the market and researchers are working out with magnetic resonance theory. Magnetic coupler design is important in sending the wireless power and it is of two types, primary coupler and pick up coupler. Themes: Dynamic charging: Dynamic charging is a way to provide charging to the EV during driving and it can provide solutions to the range anxiety while driving. In dynamic charging, there are two kinds of the magnetic coupler, one is long track coupler and other is narrow-width track coupler. With the use of narrow track design, construction cost can be decreased. In designing the track, pickup coil can cover only a little portion (Maglaras et al. 2014). Contactless power transfer: Contactless power transfer is a wireless process that can be transmitted electrical energy to the electrical devices. In case of EVs, the wireless power supply can be categorised into two, radiative and non-radiative. Moreover, in using of non-radiative techniques, power can be transmitted through magnetic fields by inductive coupling to wires and coils (Qui et al. 2014). Inductive power transfer: The principle of using the inductive power transmission is depended on the transmitting coil with another receiver coil. Two coils are coupled through magnetic inductors which induce through voltage. According to Miller et al. (2014), the more coupling will be efficient, the more the power transfer will be convenient. The distance between ratio inductors may determine the coupling strength and it can be depended on the shape and size of coils. In-motion wireless charging: Wireless Power transfer can be described as safe and convenient. It is an autonomous way of charging the vehicles as it does not require bulky charging system to carry in EVs. In-motion wireless charging helps to reduce the battery shape and increases the battery life as a whole. Question: What are the ways to use wireless charging and battery in Electrical vehicles? Findings: Wireless charging is the future of WPT and it can be used by dynamic charging. This technique is efficient, easy-to-use and convenient charging method for giving charge to the EV. This technique is helpful in the automotive industry with the beneficence of resonant magnetic induction procedure for using energy wirelessly. WPT involves disciplines of magnetic supply of energy and power electronics with the use of mechanical engineering and communication. However, a magnetic field is related to low density and high frequency. Circuit analysis is important with an analytical approach to the finite element methods. Electrification is important in transportation as it important that it cannot be avoided due to energy-related issue. Wireless charging and battery is not only the concept of charging the vehicles but also it is a customer-centric operation in a daily based worked. Further, wireless system provides the benefits of recharging in the parking space. It provides the advantage in c harging the battery in a consistent way without the complex system. The users need to have the plugs, cables; adaptors and it can multiply the charging facility with gadgets. The system of little and often charging system days are gone and the people are using this in forefront trends. An EV can be charged at anywhere and it cannot be possible at wired charging (Yilmiz and Krein 2013)). Vehicles to grid power transfer are becoming popular with bi-directional converters that have inductive links. It is important to have the converters and controllers intact with the presence of coils and wires from AC supply of energy. Conclusion Different technologies can be taken to use of wireless power transfer to the EVs, however inductive power supply with magnetic use can be helpful and it is cost effective. Coils and wires can be used to improve the efficiency. Various types of compensation topologies can be used that may increase the performance indexes. Using of wireless charging is nowadays is important as it provides relief from the burden of equipment with promoting the green energy.
