and ice particles above the freezing level collide. Once the liquid and ice particles collide, they build up large electrical fields in the clouds. A “spark” occurs whenever these electric fields become large enough to produce static electricity. The static electricity reduces the charge separation. The spark made…

ALTERNATE ENERGY GENERATION REPORT: SOLAR, HYDROELECTRICITY, WIND The world is constantly revolving around energy, as the population of the earth grows; the demand for electricity significantly increases as well. As society has evolved, technology has also evolved, becoming more focused on luxurious electronic items while also emphasizing a "greener" earth in the form of alternate energy sources. While these alternate energy sources have some obvious benefits, there are also some significant…

they spin the shaft which is connected to the electrical generator. Turbines are complicated machines that includes sophisticated gearboxes for increasing the spinning shaft speed from 30 to 60 (rpm) required by most of the generators to produce electricity. The power in the win is directly proportional to the cube of the wind speed, to make that clear, for example a 20 (KPH) wind speed will generate 8 times the power of 10 (KPH). However this doesn’t happen a lot cause of the wind change in…

Who was a better inventor LeoNardo DA Vinci or Thomas Edison? It has been long debated on who was a better inventor, Leonardo DA Vinci or Thomas Edison? Thomas Edison might have been a leading inventor in his time, because he created the light bulb but that was really his main achievement. Leonardo DA Vinci was better because he had more inventions, better known for his work, and he was specialized in many lines of inventing. Now you really need to think Thomas Edison was responsible for…

“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…
