Wikipedia is not the Enemy Project Assignment Example | Topics and Well Written Essays - 750 words

Wikipedia is not the Enemy Project - Assignment Example Its importance to the society makes it is worth being included in Wikipedia. Writing Entrepreneurship as a topic in Wikipedia is not enough. The author must ensure a proper breakdown into smaller and detailed subtopics. As an author, I would include detailed subtopics like definition and background, importance, definition and qualities of an entrepreneur and types of entrepreneurship. In the listing, I would also include the potential sources of finance for startups, forecasters of success in entrepreneurship and examples of successful entrepreneurs and entrepreneurship. At the end of the article, I would include a reference list. In the topic, the most potentially controversial parts are the definition and the sources of finance for startups parameters for measuring success because they are not measurable, and every individual can have their opinion. I would gain information on entrepreneurship from business journals, books and newspapers because they provide a lot of information (Wikipedia 1). The entry of entrepreneurship article in Wikipedia is a shorter version compared to what other sources provide. Wikipedia has divided it into numerous subtopics namely definition, background, history, definition and skills of and entrepreneur, psychological makeup, project entrepreneurship, financing, predictors of success, recent developers and referencing with further reading. The entry was last revised on 27, October 2014 at 1307 hours. The experts cited in the article include Joseph Schumpeter, Jean Baptist, Peter Drucker and Frank Knight (Wikipedia 1). The history subtopic in the article is shorter and less informative. The barriers to entrepreneurship that the article provides are outdated with the old days of 17th and 19th centuries. The 21st century needs more descriptive and informative barriers. The subtopics of background and history have been de-emphasized, and the interested reader may feel frustrated. A reader might also feel cheated

Aircraft System Principles and Applications Assignment

Aircraft System Principles and Applications - Assignment Example Effect of air density on aircraft performance Air density is responsible for lifting the aircraft at the start of flight. It is also responsible for favorable amount of fuel consumption as air density affects air fuel mixture which is burned to run the engine. Therefore, fuel consumption and lift of aircraft not only depends on density but also depends upon temperature and pressure, indirectly. Â  Effect of air pressure on aircraft performance An aircraft requires maintaining a specific pressure to keep flying in the air or to move to higher altitudes. As the lift of aircraft is directly affected by the density of air, so in order to move to higher altitudes density of aircraft must be greater than 1225 gm/m-cube. Reduction in density results in lesser amount of air molecules moving around the plane and hence, lesser amount of thrust is applied on the plane than is required to move at higher altitude(FAA). Â   Effect of air pressure on aircraft performance Air may have parcels of air that are having raised temperatures and this raised temperature significantly reduces density of air within these parcels. Whenever a plane enters from a parcel of lower temperature to a parcel of higher temperature, it undergoes variation in performance. Due to lower density, flight of plane is adversely affected and it also affects the fuel efficiency of the engine due to insufficient air required to inject fuel. Therefore, planes are equipped with turbochargers. in order to maintain air pressure. Question 2 Explain the function and operation of aircraft pneumatic systems and their associated status indicators? Old aircraft systems were based on high pressure pneumatic systems which make use of air as a power transmission medium. Most common components that make use of pneumatic system are: Brakes Closing and opening of doors Operation of emergency devices, for example landing gears, flaps etc. Driving of hydraulic and water pumps etc. Pneumatic power systems are most commonly named as vacuum pressure systems, where pressure is measured by making use of suction pressure. Vacuum pressure system facilitates following components named, pumps, relief valves, vacuum air filter, suction gauge gyro instruments(FAA). Before the air enters the pneumatic system, it is passed through the air filter in order to filter out impurities and dust particles. These particles, if enter the pneumatic system, damage the system adversely. After that it is served to the pumps which are used to pump out air at desired pressure required by the pneumatic system. It is considered the most important part of the system without which system would not work. The pumped air is
