  • Thunderstorms Research Paper

    Exploring a Childhood Concept - Thunderstorms What scares you? Concepts formed as a child often change as he or she grow into an adult; perhaps the ideas around magic or fairies. Other concepts such as fears are common, but can turn into debilitating fears or even phobias. Treatment for debilitating fears could improve children 's overall mental health, if left untreated they could lead to other disorders, such as anxiety and depression (Dingfelder, 2005). .In this paper, we will explore the concept of thunderstorms formed by a young girl, and how it lingered on until adulthood. She was not able to change this concept developed as a child until she had two young girls of her own, and was faced with a thunderstorm. Thunderstorms As A Child As a young girl growing up in rural northeast Ohio, she can remember the thunderstorms. The loud crashing and booming, the flashes of lightening and torrential downpours. She did not like thunderstorms, they scared her immensely. Her parents would try to sooth her with “everything is okay” “it is just a noise”, but she felt the unease of her parents, and was sure there was something to fear. At night, she would run into their room quite as a mouse, after a long debate with her stuffed animal friends in her room as to which she would take with her and if everyone was sure there was no thunderstorm monster lurking in the hallway. Once she was in her parents’ bedroom, she pulled out the sleeping bag stashed under the bed earlier in the night…

  • Unintended Consequences Of Global Warming

    will help any progress in the science . Denying that there is any ambiguity would not serve the scientist’s purpose as a scientist, though maybe it would as a politician. We cannot say that we know what the future holds for us. We have reasons to be uncertain, and reasons to examine these potential threats that exist on the horizon. But most of all, it is important to undertake this scientific endeavor in the name of science, welcoming doubt and distrust as a extremely important tool in the…

  • Da Vinci Vs Thomas Edison

    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…

  • Analysis Of 'The Ghost Boy And This Railroad Changed America'

    “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…

  • The Reflection Of Mechanical Power

    The wind turbines are used to change the kinetic energy to electrical energy & mechanical power as we all know that but what happens inside of that mechanism is what is important. Most turbines have from 2 to 3 blades and the wind moving over the blades causes them to rotate, as the blades rotate 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)…

  • Michael Faraday: How Thomas Edison Changed The World

    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…

  • MOSFET Case Study

    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…

  • Simulink Case Study

    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…

  • Electro Mechanical Actuator Case Study

    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…

  • AC Voltage Advantages And Disadvantages

    One of the main organs that electricity can really harm is the heart. The heart can become ‘frozen’ or fibrillated. If the heart is frozen there is a greater chance for it to return to normal beating rather than if it was fibrillated. In the case of fibrillation the heart’s muscles can all move at once and be all over the place. The heart won’t be able to function as normal. Current approaches 100milliamps or more can be fatal. The skin will result in numerous burns from the electricity and…
