“Thousands of workers from China helped build America’s Transcontinental Railroad” (Lewis). Kenneth Oppel and Kristin Lewis are both authors of two great stories with different aspects of America’s Transcontinental Railroad. Kenneth Oppel is the author of “The Ghost Boy”, a story about a fourteen year old boy named Luke is traveling on a train with his father. He happens to stumble upon a ghost; a victim to the making of the Transcontinental Railroad. Kristen Lewis is the author of an…

Introduction “What one man calls God, another calls the laws of physics.” [1]. Nikola Tesla was born in the industrial age under the Austrian empire on 10th July 1856. Being raised with advance knowledge of engineering and science, Tesla started his career with the emerging electric power industry in the early 1880’s for whom he worked for until the late 1880’s. His first significant achievement happens with AC or Alternating Current. He has owned the patents for the Alternating Current…

In 1959, metal–oxide–semiconductor field-effect transistor (MOSFET) was invented by Dawon Kahng and Martin M. (John) Atalla at Bell Labs. Julius Edgar Lilienfeld had already patented the basic principle of this kind of transistor in 1925. But later the Bell Labs edition was allocated the name bipolar junction transistor, or merely junction transistor, and design of Lilienfeld came to be identified as field effect transistor. Later, Jean Hoerni found that Silicon dioxide (SiO2) should be used to…

Andie McLeod 10/31/17 Davis P 3 Xtra Credit Report Rough Draft Thunder and Lightning. Used in the oldest of stories to express the great power of the gods, the existence of thunder and lightning has been around forever. Regardless there were no letters or primary documents of the event, we are all familiar with the story of the “kite and the key”, the Great Benjamin Franklin experiment which is responsible for the discovery of the properties of lightning, regardless he was not the first to…

4.1.4 Development of Feed Forward Control model in Simulink To implement feed forward control. Firstly, the transfer function of the linear DC Motor model has to be obtained. Actually in our case, the input of the plant is current so the transfer function of the mathematical model in ratio of angular velocity to current has to be obtained. It is given by: G(s)=Ω_1/I_a =R_A/K_M 1/(T_e s+1) where T_e=(J_meq R_A)/(K_m Cϕ) is electro-mechanical time constant. The feed forward control could be…

Scientists that i truly admire I have two scientists who I admire Thomas Alva Edison and Humphry Davy. Thomas Alva Edison is one of the best investors; Thomas Alva Edison was conceived in 1847 out of a residential community in Ohio. His instructors thought he was a moderate student, so his mom showed him herself, moving his enthusiasm for science. In 1869, subsequent to moving to New York, he enhanced a machine called the 'ticker'. It was utilized for handing-off data about the share trading…

How Electro-mechanical Actuator Works? A Rotary Electromechanical Actuation system with an Electric Motor, a gear box & an elastic spring to absorb peak torque loads experienced during operational life. The Schematic below describes the system. Fig. 1.1 Rotary Electro-mechanical Actuator Gearbox Requirements: The Gear Box at the Motor Output is intended to amplify the torque output of the Motor with reduction in speed. The tentative ratio is set at 10:1. Functional Requirements of…

Have you ever heard of Samuel Morse? If you have then you know that he was a co-inventor of Morse Code. Morse Code is a systematic way of transmitting information via code and it is sent either from light or from off and on tones. Samuel Morse is known for much more than Morse Code, however. He originally gained his reputation for being a portrait painter and by helping invent the single-wired telegraph. Because of what is being called the Industrial Revolution many new inventions like Morse Code…

bulb. Tesla worked under Edison as his apprentice when he was working on the light bulb. While Tesla was under Edison, JP Morgan was trying to find an industry that he could rise from the ground, and that's when he found Edison with electricity and the light bulb. JP Morgan went against everything his successful father ever told him when he took the risk of financially helping Edison. After Tesla pitched his idea of the AC light bulb to Edison over and over again he finally resigned.…

Sarah Ruhl's Eurydice deals with themes of the human condition. Ruhl crosses a wide spectrum of all things that make us human, including mortality, suffering, fear, ignorance, nativity, creativity, and familial and romantic love. My goal in the staging of this scene is to wake up these aspects of the human condition for each audience member individual. These experiences are universal, although there are a million different ways to experience each one. My staging will take the audience through…
