Are Computers Changing the Way Humans Think - 988 Words

There has always been controversy as to whether computers hurt the way people think. Computers have hurt society more than it has helped. Although computers have benefits such as helping you for school work in making quicker decisions for you, and it makes it easier to do essays by using word; it has also hurt society because it makes us become lazier, makes online dating dangerous, and makes people addicted to the Internet. One benefit of computers is that they help students with school work. Students are able to find things quicker for research papers, etc. Also it can be easier for students to type instead of writing out their essays. Students can get ideas from people through blogs and chat. ( Christine Zuchora - Walske 61)†¦show more content†¦People can really be meeting kidnappers or someone dangerous they don’t even know about. When they tell them about him/her self people go along with everything they have to say. Online dating can lead to violence and finding them in jail or dead. Then when all that stuff happens family members going crazy and feel sad because what has happen to their loved one. People also talk to someone from the Internet because things are going thru there mind or something is going on with them that they try to find a way to leave there house. One good reason for online dating is that some people will end up finding there true love on the Internet. Findi ng someone’s true love there can change there whole life to worse than better or vice versa it is very dangerous. Online dating should stop and they need to stop with facebook, and all the other online dating websites that they have now. Parents should know what their kids get on and they should get there passwords for any website they have and check who they communicate with that’s my opinion. Online dating needs to stop immediately! ( Ford, Matt. Web.)

The Impacts Of Premarital Sex And Cohabitation On Marriage

Phat (Kevin) Phan English 1302 Professor Randall Watson December 8th, 2014 The Impacts of Premarital Sex and Cohabitation on Marriage Becoming popular from the 1950s until now, premarital sex and premarital cohabitation have been considered as the norms in the United States. While most people agree that premarital sex is one of the ways to find out whether the couple is perfect for each other, others incline its consequences. Because the United States is described as the Salad Bowl, in which numerous ethnicities, religions, and cultures are not assimilable, it exists some different perceptions about sex out of marriage. By reviewing the reasons and pointing the consequences of having sex and living together before marriage, it is obvious†¦show more content†¦Defending the judgment that premarital sex and cohabitation is acceptable and permissible, people who had sex before their marriage or just agree with it expound some reasons. First of all, living together and sex outside marriage have been increasing because of social pressure. In a community, a person who does not follow common norms is abnormal. Acc ording to the research in 2011, Mashau learned that a person would be seen as stupid, rural, and sophisticated without participating in premarital sex as his/her peers. It means that some people might neither agree nor disagree with premarital sex, yet they try to ‘simulate’ what most people do in order to be ‘normal’. Giving another reason to protect their opinion, people believe having sex and living together before marriage help them be ready for marriage. Marriage is the most important event in a person’s life; thus, everyone wants to find a fitting spouse with whom they are going to live in the rest of the life. They worried a wrong decision will destroy their marriage, even their life. The contribution of premarital sex and cohabitation is a suitable choice which not only helps the couples understand each other but also gets their relationship closer. The couples believe engaging in sex and living together before marriage are the processes whic h they are more likely experience the needs of marriage than the couples did not. As a result, the couples that think they

Immigration And The United States - 965 Words

Immigration is what shapes the picture of today’s present-day world. Traveling from country to country for trading and other necessities or personal reasons has been popular since historic times. Immigration means the one way movement of people to a specific country or place. People, or immigrants, move out of their native country for numerous reasons. The aspiration for a better life and future and improved employment opportunities are the key driving forces for immigrants to migrate. The United States is no less than immigrants coming from diverse parts of the world. Because of this, the United States implemented immigration laws and policies. The United States immigration policy has endured great change since the era of the 20th century. There are several reasons that have subsidized to this change in policy. These reasons being poverty, lack of jobs and political problems. The United States has altered its immigration policy various times in the past century but the motive s for immigration have stayed mostly the same. Immigration has continuously played an essential role in American History. The United States current immigration policy continues to be the utmost open immigration policy in the world.

Impacts of Turbofan Engine in the Aviation Industry

Question: Discuss about the Impacts of Turbofan Engine in the Aviation Industry. Answer: Introduction Turbofan engine is among the most common type of gas turbine engine used today (Hall, 2015). The first turbofan engine was manufactured by Rolls-Royce Limited in 1950s. The engine had a by-pass ratio is 0.25. In 1960s, Volvo Flygmotor and Pratt Whitney also started manufacturing turbofan engines. Today, these engines are manufactured by different manufacturers, including General Electric, CFM International LEAP, Engine Alliance, and International Aero Engines, among others (Lucintel, 2012). The main motive of developing turbofan engine was to overcome the two main disadvantages of its predecessor, turbojet engine. The disadvantages were: poor fuel efficiency at lower altitudes and poor runway performance. Turbofan engine has successfully overcome these drawbacks of turbojet engine. Therefore turbofan engine was developed so as to replace turbojet engine. Since its invention, turbofan engine has greatly revolutionized the aviation industry by enabling quieter flights and lower fuel c onsumption by aircrafts. The purpose of this report is to discuss various elements of turbofan engine, including its components, operation, advantages and disadvantages. Operation of Turbofan Engine The basic operation of a turbofan engine is similar to that of other turbine engines, where air is drawn into the engine, compressed, mixed with fuel, ignited and exhausted to create thrust that propels the aircraft. The main components of turbofan engines are: fan, compressor, combustor, turbine and nozzle/mixer, as shown in Figure 1 below (Cutler, 2016). These components are similar to those of a turbojet except the fan. In other words, a turbofan engine has similar components to those of a turbojet engine only that the former has a fan. Figure 1: Components of a turbofan engine The fan draws in large amounts of air into the turbofan engine. The air passes through two parts. Some of it flows into the core of the engine where it will be combusted whereas some of the air (called bypass air) is directed via a duct outside the engine core (Chmiel, (n.d.)). The bypass air has three main functions: it generates additional thrust; blankets the exhaust air leaving the engine thus making the engine to produce less noise; and cools the engine. Bypass ratio is the ratio of quantity of air passing outside the core of the engine to the air passing through the engines core (Hall, 2015). According to DutchOps.com (2012), turbofan engines can be classified into two groups based on their bypass ratios: low and high bypass ratio turbofan engine. The air flows through the axial flow compressor, which uses its spinning blades to accelerate the speed of the air and compress it. Stators, which are positioned between compressor blades, converts rotational energy of the air into st atic pressure thus increasing overall air pressure. In addition, the stators straighten the air flow making it ready to move into the succeeding set of spinning blades. The air then enters the combustor where it mixes with fuel and gets ignited. The combustor comprises of several parts, as shown in Figure 2 below (Cutler, 2016). Figure 2: Parts of turbofan engine combustor The diffuser is used for slowing down air entering the combustor from the compressor, which helps in easing the ignition. Swirler and dome are used for increasing air turbulence for easy mixing with the fuel. The fuel injector supply fuel that mixes with the air to create the desired fuel/air mixture. The actual combustion occurs in the liner, which comprises of various inlets for allowing entry of air at different points within the combustion zone. The igniter is used for lighting the fire to start the actual combustion process. After leaving the combustor, the high-speed and hot air passes over the blades of the turbine. The blades draw energy from the air, rotating the turbine and engine shaft that is fixed to it. The same shaft is also connected to compressor and fan hence when the turbine rotates, the compressor and fan also keep on drawing in more air. The nozzle is where the high speed air from the turbine gets exhausted at the back of the engine thus creating a thrust that pushes the airplane forward. This is in accordance with third law of Isaac Newton, which states that for every action force creates an equal reaction force that acts in the opposite direction. Advantages off Turbofan Engine There are several advantages of a turbofan engine. Some of these advantages are as follows: Higher Fuel Efficiency A turbofan engine has a higher fuel efficiency. The engine burns less fuel than most of the other gas turbine engine thus saving fuel costs. In addition, this also reduces the amount of harmful emissions that the engine releases to the atmosphere (Whitfield, 2016). High Thrust A turbofan engine generates very high thrust compared to other turbine gas engines. The high thrust results from the air passing through the engines core and the bypass air (Stratos Jet Charters, Inc., 2010). With the other gas turbine engines, thrust is only generated by air flowing through the engines core. However, turbofan engine generates thrust from the air flowing through the engines core and the extra thrust from the bypass air flowing through the bypass duct. QuieterMotion A turbofan engine is quitter than majority of gas turbine engines. There are two factors contributing to this quietness. First, it is the bypass air that masks the exhaust air leaving the engine thus making the engine quieter. Second, it is the blades tips that are confined inside the turbofan engine casing thus controlling noise levels and preventing noise from leaving the engine casing. These two elements make the aero-acoustic properties of turbofan engines to be greater than most gas turbine engines. Greater Efficiency A turbofan engine is more efficient to control especially when the airplane is flying at low altitudes. This does not only help the pilots to be in more control of the airplane but also improves the overall safety of the persons onboard. Greater speeds A turbofan engine can fly at greater speeds than other conventional airplane engines. One of the factors enabling this is the design of the turbofan engine blades. The blade tips of a turbofan engine are designed to exceed the drag divergence speed. This capability of exceeding the drag divergence speed makes it possible to the turbofan engine to accelerate at very high speeds than most turbine gas engines. No orMinimal Vibrations A turbofan engine produces zero or very minimal vibrations. This has two benefits: it increases the comfort of the cabin crew and passengers, and also increases the longevity of aircraft components (Shields and Carmel, 2013). With less vibrations, it means that the airplane flies smoothly with minimal upheaval. Also, there are less interactions between various components of the airplane components thus reducing the likelihood of wear and tear that could otherwise cause damages and reduce the lifespan of these components. Therefore if maintained properly, turbofan engines are more durable than other gas turbine engines. Short Takeoff Balance Another major advantage of turbofan engines is that they have the capacity to facilitate short takeoff distance. The turbofan engines fan draws large amounts of air into the engine thus generating adequate thrust quickly to propel the aircraft. Therefore airplanes using turbofan engines do not require longer runway distances to takeoff as they can generate sufficient thrust within a very short distance. Disadvantages of Turbofan Engine Despite the many advantages, turbofan engines also have some disadvantages. The key disadvantages are as discussed below Larger Frontal Area The frontal area of a turbofan engine is usually larger and this is mainly because of the large size of the fan. The large frontal area helps in drawing in more air into the engine. However, this large front area usually translates into more weight. In general, turbofan engines are usually heavier than their predecessors turbojet engines. Less Efficient at Greater Altitudes One advantage is that the efficiency of a turbofan engine is greater when the airplane is flying at a lower altitude. However, this becomes a disadvantage when the airplane is moving at a higher altitude. The less efficiency at greater altitudes means that the airplane may be difficult to control and it is likely to start consuming more fuel. Conclusion Turbofan engines have had significant impacts in the aviation industry. The engines comprises of five main parts: fan, compressor, combustor, turbine and nozzle. They generate great thrust through air flowing pass the engines core and bypass air passing through bypass duct. These engines have reduced noise levels of airplane engines, increased fuel efficiencies, reduced fuel costs for many airlines, minimized carbon emissions, and increased fuel speeds. Considering its advantages, many airlines and aircraft owners/operators prefer turbofan engines than any other gas turbine engine. With the current innovative technologies, it is expected that turbofan engines will continue improving the aviation industry in different ways. Works Cited Chmiel, M. (n.d.).

Schlieffens Plan Essay Example For Students

Schlieffens Plan Essay In 1904 France and Britain signed the Entente Cordiale. The reason for this alliance was to get a few countries grouped together against the perceived threat of Germanys powerful army. Talk also began to add Russia to this alliance bringing all three, France, Britain and Russia together. As a result of these alliances the German military began to fear the possibility of being attacked from both sides all at once from France, Britain and Russia. Germany gave Alfred von Schlieffen, the German Army Chief of Staff, the responsibility for coming up with a plan to defeat the allies. This plan was called the Schlieffen Plan. The Plan involved hitting France hard, with 90 percent of the total German army. The remaining 10 percent of the army would stay back and defend again any Russian advances on Germany. Schlieffen thought that taking out France was the key to winning the war as quickly as possible. He thought that if France was defeated then Britain and Russia would not want to continue the fighting. Schlieffen estimated that it would take at least six weeks for Russia to organize there large army for an attack on Germany. This meant that it was very important that Germany was able to invade and defeat France before then. In August 1914 the Schlieffen Plan was put into effect and the German Army invaded Luxembourg and Belgium. Germany thought they would have no problem taking out the two cities but were unexpectedly held up by the Belgium army. While being held up there they were again surprised as to how quickly the Russian army was able to advance into East Prussia. Soon after which the British force also reached France and Belgium to fight against the Germans. The French and British fell back to the other side of the River Seine and regrouped. After which, another French moved in and attacked the Germans at full force and managed to cut a huge hole in the German army splitting them into two groups. The French then entered the gap between the German forces trying to keep them divided. The Germans came very close to defeating the French army until the French brought in reserve troops to reinforce the front line. The Germans could not break through the French and were soon after ordered by the German Chief of Staff to stop and retreat from the French. After the retreat the British and French then came back across the river. The Schlieffen plan did not work at all like they hoped. Germany was not able to get their quick victory over France and were instead overpowered and forced back. Although the Schlieffen Plan did not succeed, this did not mean that the German army had been beaten. The Germans retreat was a successful one and they were able to fall back and build trenches between the North Sea to the Swiss Frontier. It was good for Germany that they were able to get out in time and secure a position, but was a bad situation because it took away any possibility of a quick war.
