In 1989, “Back to the Future 2” was released in theaters. From that day on, people had become enamored with the idea of a hover board. A form of transportation that didn’t require the use of wheels. One that did not have the problems of traveling over various types of surfaces. Whether it was grass, dirt, concrete, or water. The hover board would move as long as there was enough momentum and a way for the person to push the board forward. In the 27 years since the movie, many people have tried to

electricity to homes, businesses and industry, all of which were made possible by electrical engineers. Some of the most prominent pioneers in electrical engineering include Thomas Edison (electric light bulb), George Westinghouse (alternating current), Nikola Tesla (induction motor), Guglielmo Marconi (radio) and Philo T. Farnsworth (television). These innovators turned ideas and concepts about electricity into practical devices and systems that ushered in the modern age. The field now covers

researchers because these media can support negative reflection and refraction. That is; when a perfect electric conductor (PEC) interface is placed in a chiral nihility medium, only a backward wave can be seen as a reflected wave, whereas in chiral media two reflected forward waves can exist [7,22-25]. is the modal effective refractive index. For guided modes to occur within the core and evanescent tails within the cladding we require: 0 and 0 2 2 2 2 c f k k . For surface modes to

“Cyborg: a person whose body contains mechanical or electrical devices and whose abilities are greater than the abilities of normal humans” (Merriam-Webster). Neil Harbisson, self-proclaimed cyborg is standing on the platform at the TED Global Conference 2012 in Edinburgh, Scotland in quite a colorful ensemble with something that looks like a microphone attached to his head. This immediately captures my attention and I start wondering where this is going to go. Harbisson is both human and machine

Abstract-This paper is based on the “Three phase motors protection” from various faults. This paper emphalis on various difficulties such as phase reversal in single and three phase systems, dropout of line, damage due to overload, failure of single phase there will be usually recommended to perform in complex environmental conditions. This includes in built cut-off frequency having several facilities together with timer in off condition and a starter which is automatic. This main circuit of this

Electricity is a form of energy resulting from the existence of charged particles such as electrons either statically as a charge as a current. Electricity has to do with electrons by When these electrons move between the atoms, a current of electricity is created. But since electricity is a natural force that exists in our world, it didn't have to be invented. Most of the people give credit to Benjamin Franklin for discovering electricity, but Benjamin Franklin had one of the greatest scientific

Nikola Tesla Hi today we will be talking about an australian immigrant named Nikola Tesla he was born on July 10,1856 in smiljan croatia.But today it is now just croatia in his time Tesla went to america to become an inventor in 1884.Back then thousands of immigrants were all crammed on to one boat and if they wanted to bring anything valueable there was a little space for lugage.When Nikola went to america he worked with Thomas Edison over time Tesla and Edison grew to be ferice competers but rather

oscillator is a simple one to implement and being a current oscillator it is helpful for the system [1]. The AC power is then transferred wirelessly through inductive coupling. In inductive coupling power is transferred between coils of wire by a magnetic field. Fig. 2 shows the block diagram for the wireless power transfer through inductive coupling. The transmitter and receiver coils together form a transformer. An alternating current (AC) through the transmitter coil (L1) creates an oscillating
