This link sends you to a short biography about Nikola Tesla. Nikola Tesla got encouraged by his mom to start his career. He started his career by going to America by boat and he was hired by Thomas Edison to do basic electrical engineering. Soon after that, he started redesigning the direct current generators that ran Edison’s business. Then Edison offered Tesla $50,000 for the new improvements on the generators. After Tesla’s work was done, Edison claimed that he wasn’t serious about the…

I am a student of electrical and electronic Engineering and I like taking up my further studies with an outlook of innovative research. I frame my goals in that direction and put up the hard work to realize them as I strongly believe that the hard work is the key to success. I have a strong feeling that whatever the goals I have and whatever the strong frame work I prepare, the set goals may not be realized unless there is congenial academic environment and also an efficient academic agency to…

Thomas Alva Edison possessed a tremendous amount of skills as an inventor and dedicated a great amount of time and efforts in his laboratory. Edison realized at a young age that creating and inventing intrigued him. He drafted a great amount of notebooks containing sketches, ideas, and explanations for his inventions. His ambitions and aspirations led Edison to own many companies and accumulate over 1,000 patents for his inventions. As an inventor, Thomas grew up with a mindset that he would…

1.1 Dielectric Materials Dielectric materials are insulating materials that exhibit the property of electrical polarization. Dielectric materials support charge by acquiring a polarisation in an electric field. 1.1.1 Electric susceptibility and permittivity When a capacitor with capacitance C0 is filled with a dielectric material, its charge storage capacity (capacitance) increases to a value of C. Than susceptibility (χ^') of the dielectric materials is given by χ^'= (C-C_0)/C Dielectric…

Paving the way for a getter future, and becoming an Electrical Engineer. Many reasons are responsible for this sudden career change. After discussing a ling self-evaluation with my wife, whom I trust more than one, we feel that a change may be needed for our children to have certain opportunities. As a result, I have decided to pursue a career in Electrical Engineering with a primary goal in mind—becoming a Sr. Engineer. I believe now is the right time to begin a new career change. Not only is…

3.4. Electrochemical performance of Li1.2Ni0.13Co0.13Mn0.54O2 3.4.1. Electrochemical charge/discharge behavior Figure 9 (a-d) shows the charge/discharge profiles of four Li1.2Ni0.13Co0.13Mn0.54O2 electrodes (EV, CA/EDTA, CA and EDTA) cycled at 0.1C between 2.0 and 4.8 V, while Fig. 9(e) depicts the initial charge/discharge profiles of four Li1.2Ni0.13Co0.13Mn0.54O2 electrodes under the same conditions. All the initial charge/discharge profiles show the same general features. All the initial…

Once he returned home he began drawing the plans for his electrical telegraph. His first model was composed of a wooden frame, which would hold an electromagnet, paper, and a marking pencil suspended from a pendulum. The pencil would mark on the paper as the electric circuit was opened and closed. What is now known today as Morse code is what Samuel Morse created when he used dots and dashes in his telegraph. To continue his experiments and research he needed financial support. Fortunately,…

Explanation of EMG signals EMG stands for electromyography. Muscle fibres generate tiny electrical currents prior to the production of muscle force. These currents are generated by the exchange of ions across muscle fibres membranes, a part of the signalling process for the muscle fibres to contract. EMG is the signal made, it can be measured by applying conductive elements or electrodes to the skin surface, or invasively with the muscle. When using EMG, tiny devices named electrodes are used…

James Watt: He Made it Better Imagine the world without trains? Meaning, there would not be a thomas the train to teach kids important life lessons through the TV and children's books. I don’t know about you but a world without Thomas the train is not a world I would want to live in. Remember the family favorite book and later movie called “The Polar Express?” How weird would it have been if instead of going to the North pole by a magical train, they traveled by car or plane. Totally ruins the…

Thomas Edison was one of the greatest inventors and entrepreneurs of the Gilded Age, bringing forth great changes in our society many years ago. Some may be wondering why someone would say this, primarily knowing Edison as the inventor of the modern day lightbulb, but there is more to the inventor than meets the eye upon further examination. Entrepreneurs are defined by the Edison Innovation Foundation as “agents of change”, who create products and services for the world, thus creating massive…
