The prop ortion of legal person shares is relatively concentrated, they have the ability to supervise the management of commercial banks in the management of the behavior, so that it is more in line with the interests of shareholders. The proportion of legal person shares is large, because the legal person shares cannot flow, can only transfer agreement, with strong stability, and therefore they are more concerned about the long-term development of commercial banks, they have stronger motivation to supervise and control the commercial bank management. Therefore, to increase the proportion of corporate shares, improve the modern enterprise system of commercial banks, play its role in the supervision of bank governance, so that the corporate shareholders in the management of commercial banks play a more important role is to improve the performance of commercial banks is an inevitable choice. 1.3 increase the proportion of floating shares of Listed Banks The empirical results show that there is no obvious correlation between the proportion of tradable shares and bank performance, but this does not mean that the proportion of tradableShow MoreRelatedThe Financial Analysis Of Terms On The Tunisian Stock Exchange1252 Words   |  6 Pages Table 2 of the descriptive statistics shows a summary of the variables that were taken from the financial statements and the annual reports of sampled firms on the Tunisian Stock Exchange.

History Of The Aircraft Propeller Essay Example For Students

History Of The Aircraft Propeller Essay History of the PropellerThe aircraft propeller looks like a simple mechanism to the uneducated individual. To the educated, an aircraft propeller represents the highest sophistication in aerodynamics, mechanical engineering and structural design. This report will touch on the history of the propeller, from early pioneers/experiments, advancement during/after the war, all the way up to current applications of the propeller. The creation of the propeller can be traced back to Leonardo da Vinci. Da Vincis ?helical screw? helicopter is believed to be the ancestor of the air propeller and the helicopter rotor. The first idea of a propulsive airscrew, however, belongs to J.P. Paucton, a French mathematician. Paucton envisioned a flying machine that had two airscrews, one for propulsion and the other for sustaining flight. The idea of using an airscrew for propulsion was utilized during the late 1700s to early 1800s. Only after experimentation did the inventors conclude that more propulsive power could be obtained by merely straightening out the surface of the airscrew blades. Attempts to utilize the ?straight blade? propeller were made by balloonists. These contraptions were quite strange and hardly fulfilled their purpose of actually propelling the balloon. The basic propeller had evolved from the simple concepts of da Vinci, and was slowly becoming an effective means of aerial propulsion. To reach the next plateau of flight an increased knowledge of the propeller would be needed, and the mysteries of the propeller and mechanical power would need to be solved. These substantial tasks remained for aviations pioneers to tackle during the 19th century. Throughout the 19th century, aviation pioneers explored and tinkered with the concepts of flight to design a viable airship. Some pioneers tried to transform the balloons into navigable cigar shaped airships by experimenting with sails, propellers, and paddlewheels but all produced limited results. Other experimenters, who were convinced that man flight should have wings, worked to establish basic principles in aerodynamics, flight stability and control, as well as propulsion. Controlled mechanical flight came on August 9, 1884. Charles Renard and A.C. Krebs flew the airship ?La France? on a closed circuit from Chalais-Meudon to Villacoublay and back in 23 minutes. The airship ?La France? was powered by a 9 horsepower electric motor that drove a 23ft diameter propeller and reached a speed of 14.5 mph. This flight was the birth of the dirigible, a steerable, lighter-than-air ship with adequate propulsion. Another important milestone in aviation, was the understanding of aerodynamics. Sir George Cayley, a British theorist, was acclaimed as the father of aerodynamics. He established a solid foundation of aerodynamic principles that were essential to the success of other pioneers. In 1875, Thomas Moy created a large model that had twin 12ft propellers with 6 blades each! Interestingly enough these blades could be adjusted to produce maximum thrust under certain conditions, an early recognition of the need for changing blade pitch. Without a doubt, the most expensive and spectacular project of its time was that carried out by Sir Hiram Maxim. His numerous experiments with propellers, culminated in the construction of a huge, four-ton biplane in 1890. This contraption was powered by two 180hp steam engines that each drove propellers 17ft, 10inches in diameter and weighing 135lbs. The two-blade propellers, inversely tapered and squared at the tips 5 ? ft wide, were made of American Pine, planed smooth, covered with glued canvas and stayed to the propeller shafts with steel wire to handle the high thrust loads. These massive propellers produced 1,100lbs of thrust each during full power while rotating at 425rpm. Maxims jumbo creation didnt last long however, it jumped the test track and suffered extensive damage. Dmitry Ivanovich Mendeleleyev Was Born In The Town Of Tobolsk, Siberia EssayAdvanced applications of the propeller are currently being experimented by Hamilton Standard. The new idea deals with transport category aircraft and the introduction of the ?un-ducted fan?. This design incorporates the reliability of the turbine engine, with the efficiency of a prop. Expected savings of 25% in fuel costs drive the ongoing interest in this application. The design utilizes 8-10 thin but very wide, closely spaced, swept angle blades to propel an aircraft at speeds approaching the speed of sound (mach .8). It will be interesting to see how the role of the propeller develops as time goes on. This report has sparked my interest in propellers. I have never researched this topic before and feel that Ive benefited from writing it. I enjoyed researching the history of the propeller and its contributions to aviation milestones. Ive taken you, the reader, from the early experiments of da Vinci, the wo oden props of the Wright brothers, the design of the variable pitch propeller, through the advanced concept of the ?un-ducted? fan. I hope this report was as interesting to read as it was to write.

Matrix Essays - Fictional Cyborgs, The Matrix, Australian Films

Matrix The Matrix (1999) is an extension of the existentialist motifs of the mid 20th Century set in the 23rd, for its obvious influences from the American Noir Style. This is apparent when looking at the five points of this existentialism. First, Thomas A. Anderson (Keanu Reeves), a.k.a. "Neo," is portrayed from the beginning of the film as a "normal Joe" who holds the potential of a world savior, yet without the narcissism. He does not have X-ray vision or the ability to leap tall buildings in a single bound, but rather, he is a lowly computer programmer for a respectable computer company. He does not appear important to anyone else in the film at first, and it is because of his lifestyle. Mister Anderson is immersed in the world of computers. As a result, he is lonely and alienated from the world or "reality." This feeling is also reflected in the high, swooping camera angle found in the film, which is characteristically Noir. But what is reality? The truth? "Neo" makes the conscious choice to "see how deep the rabbit hole goes." One finds out later in the film that at the point of making such a choice, he was nothing... or nothing more than an oversized Energizer; but upon choosing the "truth" he is also trying to "free his mind" from the prison he cannot taste or touch or see. Neo is doomed to fail, as no one has come before him to succeed in the freeing of his own mind. As a result, he is under a sentence of death; the system is set up against him; the Matrix has him... he struggles with the choice between life and death, as he must let his instructor, Morpheus (Lawrence Fishburne), die or sacrifice himself to save him. There is only one element holding his life in tact: Fate... At first, Mister Anderson does not like the idea of fate, as he cannot stand the idea of not being able to control his own destiny. Throughout the entire film, as Mister Anderson further transpires to his alter ego Neo, he struggles to accept the reality of his destiny. But something happens that makes Mister Anderson realize the authenticity of his destiny; he learns that he is, in fact, "the One" who is to save the world from Artificial Intelligence. No one can change their destiny if they do not realize that their pseudo-reality is a part of them. There are also other characteristics of a Noir film in the Matrix. The chiaroscuro lighting is very apparent in many scenes. Also, it invokes a great sense of alienation with its Noir-like high angle shots. The entire film is very dark and rainy. There are also many reflections, which are found in many Noir films, such as Orson Welles' Citizen Kane (1941). Kane was an obvious motivation and influence on this film, as was Alfred Hitchcock's Rope (1948), as mentioned by producer Joel Silver, editor Zach Staenberg and Effects Supervisor John Gaeta. These people had the Noir template in consideration when writing and editing this film. It is evident that Agent Smith (Hugo Weaving), the head Sentient Program hunting Neo, is the hard-boiled detective, and Neo is the "Fugitive from a Chain Gang" that is always on the run. Moreover, there is the classic "tilt shot" seen in the film that clues the viewer to the film's Noir-like style. This modern-day, science fiction, Kung Fu fighting Neo-Noir (no pun intended) thriller is clearly rooted in film classics from the past. "Wake up, Neo... The Matrix has you..." Thomas A. Anderson is a respectable software programmer for a respectable computer company. He pays his taxes, has a social security number, and even helps his landlady take out her garbage. He's just a normal guy in a normal job, doing the normal thing, much like Sam Spade in the Maltese Falcon. But one thing the viewer does not count on is Mister Anderson's alter ego, Neo, to be one of the world's most renowned computer hackers, guilty of virtually ever computer crime there is a law for. It is not until this e-lifestyle starts to spill over into his "real" life that he must start to make choices... choices that will forever change the way he sees the world, and changes that will forever impact his effect on that world. Neo feels alone in his quest for the "Truth." He is trying desperately to find out what is out there, and most importantly, "What is the Matrix?" He begins to
