...Development of the F-117 began as a top secret "black project" at Lockheed's famed Advanced Development Projects unit, better known as the "Skunk Works." First developing a model of the new aircraft in 1975, dubbed the "Hopeless Diamond" due to its odd shape, Lockheed built two test aircraft under the Have Blue contract to test the design's radar-defying properties. Smaller than the F-117, the Have Blue planes flew night test missions over the Nevada desert between 1977 and 1979. Utilizing the F-16's single-axis fly-by-wire system, the Have Blue planes solved the instability issues and were invisible to radar. Pleased with the program's results, the US Air Force issued a contract to Lockheed on November 1, 1978, for the design and production...

...Film Critique: STEALTH Cheri Adams ENG225 Instructor: Matthew Norsworthy May 15, 2011 Film Critique: Stealth Stealth was made in 2005 and is presented by Columbia Pictures, directed by Rob Cohen, Produced by Mike Medavoy. The Executive Producer was Arnold Messer. The movie starts out with wording and music, similar to Star Wars, giving the prologue of the movie. I feel that the Director’s vision is that he is trying to warn us about what the future is capable of happening, if we put “brains” in computers. In this thesis I will be telling you about the movie so you will be able to understand what is happening. I will also be telling you who is in the movie and what their roles are, the style and directing of the movie. I will also Critique the film regarding the flaws that was done, the editing to the style and the acting. The Original music was done by BT. Music plays throughout the movie; the colors are neutral at the beginning of the movie with certain key items showing full color, in one scene a United States flag is flying on a building. Dean Semler does the Cinematography’s work. His work includes Secretariat (2010) and Mad Max: Fury Road (pre-production) (2012). Stephen Rivhin did the film editing. His most recent work was Avatar (2009), Pirates of the Caribbean: At World’s End (2007) and Pirates of the Caribbean: Dead Man’s Chest (2006). Making a movie is a genuinely collaborative effort...

...Military Technology Technology in the military has greatly increased strength and eased the ranking among world powers and effected the development of new military weapons. The term "Survival of the fittest" means that the strong will succeed but the meek will not, this is the case with military technology. The U.S. has the best technology in the world, therefore we are the highest military power. Technology is a very important part of warfare. Technology is driven by the military. The army's race during the cold war, spawned some of the greatest technical achievements in human history. Space travel for example is a result of the X-plane project. The Internet was produced by the military as well. If we stop investing in military technology, we risk our safety. If other nations had more advance technology than we do, they would have more power than we do. If that was to happen, we face the threat of that nation taking over us. Military technology may be divided into five categories. Offensive arms harm the enemy, while defensive weapons ward off offensive attacks. Transportation technology moves soldiers and weaponry; communications coordinate the movements of armed forces; and sensors detect forces and guide weaponry. There are many types of technological developments in the military happening at all times. They range from new aircraft to sophisticated guidance systems. Teams of specialists work for years to develop some of our simplest equipment. These people's...

...Sleight of Hand, Sleight of Mind Orson Welles' F for Fake and the Art of the Cinematic Con Orson Welles' 1974 "film essay" F for Fake opens with a scene of Welles, in the role of a magician, performing a sleight of hand trick with a young child, "transforming" the key the young boy has presented him into a coin and then showing how the young boy had the key all the time in his pocket. The magic was the perfect illustration of Welles' purpose in the film. F for Fake was a film about fraud and deceit, about how the makers of art (and, in particular, film) use "trickery" to fool their intended audience into believing something that is not true. The film focuses on three known "charlatans" (Elmyr de Hory, Clifford Irving, and Welles himself) who used their talents to produce such magnificent forgeries that they were able to fool everyone (even so-called "experts") into believing in the truth of their claims. Despite the status of this film as one of Welles' "minor" films from late in his life (it was one of the last films he completed prior to his death in 1985), it has had a tremendous impact on filmmaking, both in a technical sense (the film's complex editing of various film stocks and styles) and in a textual sense. Welles' identification of the ways in which an audience can be manipulated into believing anything as long as it has the "air" of authenticity has had a tremendous impact on current filmmaking, especially in the realm of horror filmmaking with the current crop...

Introduction (Background and Purpose) The data use for this paper was constructed in the following way. The data are drawn from the OPE Campus Safety and Security Statistics website database to which crime statistics (as of the 2010 data collection) are submitted annually, via a web-based data collection, by all postsecondary institutions that receive Title IV funding (i.e., those that participate in federal student aid programs). This data collection is required by the Jeanne Clery Disclosure of Campus Security Policy and Campus Crime Statistics Act and the Higher Education Opportunity Act. The outcome of this process was that the enrolments is not influenced significantly by the price or living conditions of the campus. When reading some articles I was personally very surprised about this since normally the living conditions should be influent more than the other factors in the enrolments. Based on this, I was very interested which other factors influence to students’ decisions. That is why I chose this dataset to analyze for the final term paper in the course of econometrics. 2.

...camera). Aperture size is usually calibrated in f-numbers or f-stops. i.e. those little numbers engraved on the lens barrel like f22 (f/22),16 (f/16), f/11, f/8.0, f/5.6, f/4.0, f/2.8, f/2.0, f/1.8 etc. Each of this value represents one time the amount of light either more or less in quantity. Meaning to say, f/16 will let in 1X the amount of light than a diaphragm opening of f/22 and so forth; while on the other hand, an aperture of f/4.0 will let in 1X lesser than that of f/2.8 etc. . (i) As controller of light • Also known as the f-nos, changing the size of the aperture the lens opening through which the light enters the camera can change the exposure the amount of light that reaches the film. • Whereas the shutter speeds controls the length of time light strikes the film the f-no controls the brightness of the light. • It works like the pupil of an eye i.e. it can be enlarged or contracted to admit more light or less. • In a camera, this is done with a diaphragm which is a thin overlapping metal leaves located inside the lens. The leaves are movable – meaning they can be swung out of the way so that most of the light reaches the surface of the lens passes through. • They can be closed so that the aperture becomes very small and allows little light to pass. • The aperture size is indicated by f-nos or f-stop. The standardized series of numbers commonly used on the f-stop scale runs as follows:...

...Light The main factors effecting a photo when using a camera are ISO, the aperture and the shutter speed. ISO is the level of sensitivity to available light. The numbers usually are low if the sensitivity is low compared to available light and high if there is more sensitivity. However the higher the sensitivity, the higher he grain. This can be affective if this is the style you want, however you have to remember the aperture effects the image. Shutter Speed is the length of time a camera shutter is open to expose light into the camera. The measurements usually range from fractions of a seconds to actual seconds. Slow shutter speeds allow more light into the camera and are used for low-light and night photography, while fast shutter speeds help to freeze motion so can be used to create action shots. The aperture is the hole within in the lens hat allows he light to get into the camera. The larger the hole, the more light passes to the camera and vice versa. Aperture also controls the depth of field, which is the section you image that is in focus. If the aperture is very small, the depth of field is large, while if the aperture is large, the depth of field is small. As you take an image and press the shutter button, the subject enters your camera lens in a form of light. If your subject is well-lit, there is plenty of light that travels into the lens, whereas if you are taking a picture in a dim environment, there is not much light that travels into the lens. When...

...Lexus LFA – Love at first sight. Lexus has long been a luxury car contributor to the motoring world, so when it was announced that they have been working on a 200mph supercar, I was quite skeptical about it. I mean, Lexus? With a supercar? Is it going to be hideous? Is it going to be a total failure? Is it going to tarnish their name altogether? There were the ones who thought it would be a step too high, and then there were the people who were pretty excited as to how this supercar would actually turn out afterall. Either way, in one way or another, everyone wanted to see what this 200mph lexus supercar was going to be all about. Did lexus pull this one off? First came the figures.A naturally aspirated V10 engine, 552 bhp, six-speed automated sequential gearbox, top speed of 203mph, 0-100km/h in 3.7 seconds. Not bad, sounds like a proper supercar to me. Then came the price,a whopping US$375,000. We all know Lexus is technically Toyota and they weren’t the best at making supercars before this. So to command a hefty price tag for something this company has never tried before (a shot at a 200mph supercar that is), I hoped for the best nevertheless. The Lexus LFA was unveiled on the 21st of October 2009 at the 41st biennial Tokyo Motor Show. A white supercar with a carbon fiber roof and a rear spoiler that would automatically be deployed at speeds above 50mph. I fell in love with the car the moment I saw the pictures. Before this, no supercar was my dream car, the Ferraris and...
