...philosophical work of Immanuel Kant (Schultz & Schultz, 2011). Kant believed that experiences were created not from association, but through the perception of those experiences (Schultz & Schultz, 2011). There is a certain level of individuality in this statement, as individual perception is not something that can be simply classified in a way that was satisfactory to a more scientific model. For me, seeing the color green immediately leads me to reflect upon my grandmother and my great deal of pleasant experiences and memories. My perception of the color green, therefore, is wholly distinct from a simplistic explanation of the hue or tone of the color. Another interesting influence of Gestalt psychology was physics professor Ernst Mach. Mach used his physics background to explain that perceptions of objects do not change, although the meaning of the object might (Schultz & Schultz, 2011). Going back to my earlier example, the color purple is still perceived as the color purple, but the meaning and the experience related to my perception of the color might in fact be different from...

...child I’ve been fascinated with military aircraft and the pursuit of speed. From the Bell X-1 to the famed SR-71 Blackbird and beyond, high-speed flight has been a chase toward an ever increasing limit. Several factors contribute to the aerodynamics of supersonic flight and many limitations apply as the envelope is pushed. I will focus the perspective of this paper on design characteristics, engine technology, and atmospheric considerations and take a peek into the future of hypersonic flight. In order to discuss the design characteristics of high-speed aircraft, a definition for the speed regimes must be given. Supersonic flight is typically defined as greater than Mach 1 but less than Mach 3. “High” Supersonic flight is a narrow band of operation from Mach 3 to 5 and hypersonic flight is in excess of Mach 5 (Benson, 2013). Shape technology and wing design are the primary areas of concern in setting out to build an aircraft capable of supersonic speeds. If airflow velocities reach sonic speeds at some location on an aircraft further acceleration results in the onset of compressibility effects such as shock wave formation, drag increase, buffeting, stability, and control difficulties (FAA, 2008). The shock wave produced by transonic and supersonic flight is responsible for most problems with airflow and can ultimately lead to flow separation, which will destroy lift. Modern aircraft wings are designed to mitigate these issues. One of the most uniform...

...Aerodynamics of Supersonic Aircraft Name: Institution: Aerodynamics of Supersonic Aircraft The world over the past three decades has experienced manned aircraft travelling at supersonic speeds. Supersonic aircraft exhibit a much higher propulsion system as opposed to the previous aircraft, therefore, they are more efficient (Winchester, 2008). In this respect, the designer cannot allow this efficiency to drop below the theoretical optimum in spite of the increased complexity and weight. In addition, these types of aircraft have a greater interaction between the airframe and the engine than their previous counterparts. Apparently, it is no longer possible to rationalize between optimizing a propulsion package to a separately optimized airframe (Torenbeek, 2013). The two parts work in tandem and thus they should be fully integrated into all aspects by the designer. Supersonic aircraft refer to those planes that travel at a relatively faster speed compared to that of sound (Gunston, 2008). These types of planes were developed in the mid-twentieth century and had been extensively deployed purely for research and military works. Two types of airlines, namely the Concorde and the A-11/SR-71 aircraft mark the development of a novel class of planes designed purposely for supersonic operation. The most typical example of a supersonic aircraft is the jet fighter, however, it does not travel at a speed that exceeds that of sound. Other examples include the Conair B-58 and XB-70 (Mindling...

...DIFFERENT TYPES OF AIRCRAFT ENGINE AIR INLET Air intake (inlet) — For subsonic aircraft, the inlet is a duct which is required to ensure smooth airflow into the engine despite air approaching the inlet from directions other than straight ahead. This occurs on the ground from cross winds and in flight with aircraft pitch and yaw motions. The duct length is minimized to reduce drag and weight.[1] Air enters the compressor at about half the speed of sound so at flight speeds lower than this the flow will accelerate along the inlet and at higher flight speeds it will slow down. Thus the internal profile of the inlet has to accommodate both accelerating and diffusing flow without undue losses. For supersonic aircraft, the inlet has features such as cones and ramps to produce the most efficient series of shockwaves which form when supersonic flow slows down. The air slows down from the flight speed to subsonic velocity through the shockwaves, then to about half the speed of sound at the compressor through the subsonic part of the inlet. The particular system of shockwaves is chosen, with regard to many constraints such as cost and operational needs, to minimize losses which in turn maximizes the pressure recovery at the compressor. An intake, or especially for aircraft inlet, is an air intake for an engine. Because the modern internal combustion engine is in essence a powerful air pump, like the exhaust system on an engine, the intake must be carefully engineered and tuned...

...Persuasive Messages Christina Morgan Com 295 September 21, 2015 Edward Dempsey Persuasive Messages Dear Sir., The creative production team has come up a design for a new car. Now that the design of muscle cars is coming back we want to introduce a new muscle car that is a combination of all the classics such as the; 1964 ½ Mustang Mach 1, 1979 Grand Torino GT, Cobra 428, 1968 Shelby Mustang, and the 1971 Mustang Boss 351. Each of these provided a unique design on their own with similar motor styles. The current name we are calling this is the “The Cobra Sting”. With the economy on the rise and car sales picking back with a renewed interest in muscle cars that has not been seen in many years we believe that with the right design, this car could put Ford back on the #1 sales list. Each member of the creative production team agreed that the ultimate muscle car appeals to all demographics of age and sex. Instead of mass production, we suggest producing only 50 to 60 show room modules. This will give clients something to view, test drive, and inspect. We can allow custom orders for certain colors, though we believe that there should be one model with all the pluses of modern technology with the design of the classics. Today’s cars are made of plastic and fiber glass, this car “The Cobra Sting” should go back to the roots of the classics of metal with a combination of fiberglass. According to Bankrate.com the Ford Mustang Cobra is still ranked the #1 Muscle Car in America...

...Shock Waves (2009) 19:453–468 DOI 10.1007/s00193-009-0220-z ORIGINAL ARTICLE Some physical aspects of shock wave/boundary layer interactions Jean Délery · Jean-Paul Dussauge Received: 9 February 2009 / Accepted: 29 June 2009 / Published online: 26 July 2009 © Springer-Verlag 2009 Abstract When the flow past a vehicle flying at high velocity becomes supersonic, shock waves form, caused either by a change in the slope of a surface, a downstream obstacle or a back pressure constraining the flow to become subsonic. In modern aerodynamics, one can cite a large number of circumstances where shock waves are present. The encounter of a shock wave with a boundary layer results in complex phenomena because of the rapid retardation of the boundary layer flow and the propagation of the shock in a multilayered structure. The consequence of shock wave/ boundary layer interaction (SWBLI) are multiple and often critical for the vehicle or machine performance. The shock submits the boundary layer to an adverse pressure gradient which may strongly distort its velocity profile. At the same time, in turbulent flows, turbulence production is enhanced which amplifies the viscous dissipation leading to aggravated performance losses. In addition, shock-induced separation most often results in large unsteadiness which can damage the vehicle structure or, at least, severely limit its performance. The article first presents basic and well-established results on the physics of SWBLI corresponding to...

...Understanding Machiavellianism and Narcissism Roshan Priyadarshi (B14103) Vishwajeet Goel (B14121) Madhur Maheshwari Tanveer Ali (B14118) Ankur Gupta Section B Abstract This paper tries to explore the concept of Narcissism and Machiavellianism and the effect of these on a person’s personality as a whole. Narcissism, personality trait of egoism, conceit, or simple selfishness and Machiavellianism, employment of cunning and duplicity in statecraft or in general conduct, if in excess seem to have a negative effect on a person’s behaviour. The characteristics of the person indulging in these traits are analysed through this research and also the effects of their presence in excess to . Machiavellianism and narcissism can be called to be some of the most important and governing constituents of one’s personality and thus governs the behaviour of people at their workplace or in their decision making to a great extent. Consequences of very high or very low Machiavellianism and narcissism can be grave and therefore effects of both these conditions are evaluated. Also methodologies to determine the level of Narcissism and Machiavellianism in an individual are discussed through this paper. Hopefully this research will provide insights to the positive and negative effects of Narcissism and Machiavellianism and assist the reader in avoiding or minimising the negative effects of these. Narcissism The term was coined by Freud after Narcissus who in Greek myth was a pathologically...

...and turbo jet engines. Nozzles come in several different types, whether its convergent, divergent, convergent –divergent and divergent-convergent nozzle. Convergent nozzles are used to accelerate subsonic flow to sonic (m=1) and a convergent divergent nozzle accelerates the flow from sonic to supersonic. This investigation looks into the flow of a fluid through a converging nozzle therefore subsonic and sonic flow will be considered. Objective To study the thrust produced by a convergent nozzle operating under both subsonic and choked conditions. This was achieved using three methods; firstly by calculating the volumetric flow rate (Q) for each condition then plotting these results against the pressure ratio. From these graphs the Mach number can be deduced at the throat of the nozzle. At the throat of the nozzle is also where choking occurs when the appropriate conditions are applied. The last step is to produce a graph of non-dimensional thrust for each condition against the pressure ratio. Background Theory A nozzle is a mechanical device that is designed to control the characteristics of a fluid as it exits from an enclosed chamber into a different medium. All gas turbine engines have nozzles that produce thrust, to conduct the exhaust gases back to the free stream and to set the mass flow rate through the engine. The nozzle is usually located downstream of the...

...Stephanie Snowden FIN 322 Assignment 1 The State of South Carolina 1. The state of South Carolina is planning to invest state pension money in the stock market as a result of the efforts of city Treasurer Richard Eckstrom who believed that instead of investing the state pension funds exclusively in government and corporate bonds, diversification into equity securities would substantially increase return on investment without substantially increasing risk. 2. Investing in the stock market involves more risk than investing in bonds, and stocks are not guaranteed to return anything to the investor. However, investing in the stock market also presents the possibility for higher returns, the benefit of partial ownership in a company and the unlimited potential of a rising stock price, as well as the opportunity of further diversification of the portfolio. 3. The differences in return between stocks and bonds are that stocks have a higher return than bonds as shown with the average returns. Bonds have an average return ranging from about 3% to about 6% while stocks show an average return of about 13%. The risk in investments between stocks and bonds are shown in the standard deviation. While bonds have lower returns they also are less risky and less volatile than stocks. The volatility of bonds range from about 4% to about 9% while the volatility of stocks is about 20%. 4.

...for the compressors, however, axial and centrifugal compressors do have different efficiencies. Similarly, equal basis leads to have the same temperature approach for the air-cooler (or water coolers), however between mixed refrigerant and propane, the heat exchange area will be much lower for mixed refrigerant if the approach is kept identical. The end flash vapour quantity has also a big influence on the process efficiency, but each process has a different fuel gas consumption. Those added factors may lead to wide differences. Axens has calculated the effect of all those parameters on efficiency. The equipment characteristics play also an important role in the comparison: the limitations of axial compressors, of centrifugal compressors (Mach number) and possibly spiral-wound exchangers maximum size do have to be taken into account. Even the gas turbines or alternative drivers chosen can be well adapted to one process, but not to the other.
