Electric chair

First off, for this compare and contrast, I will be talking about the similarities between the two cars. The first similarity is the leather. They both have leather interior but I prefer the Chevy’s leather as it looks more fitting. The leather in the Jetta looked forced to be in the car, it didn’t look natural. The second similarity is the price range. These cars are both very affordable, even for younger high school kids if they have the motivation to save. The Volkswagen Jetta is about…

To facilitate an accurate description of the localized d and f electrons in the solids, the self interaction correction is introduced. Within the LSDA, the spurious self-interaction tends to underestimate their localization. In SIC-LDA formalism, the localized electrons see a potential (SIC potential) different from that of the delocalized ones for which the self-interaction vanishes and whose potential therefore reduces to that of the LSDA. It is known that self-interaction is important only…

Given the current outlook of the lithium-ion battery market, it is time for The Electric Company (TEC) to make its next great leap: an international venture. The coming growth of the electric vehicle industry and the feasible landscape for TEC’s rise to market dominance makes now the time to move. Then, since the decision for expansion seems to be nothing more than an afterthought at this point, the question becomes where? Based on a number of exogenous factors, as well as intrinsic qualities,…

Motor & Gearbox The mirrors are required to rotate specific angles. To be able to achieve specific angles we need a stepper motor. The stepper motor is known to divide one revolution into equal steps which is our main requirements for the rotation of the mirrors. Figure ‎2-13: The Stepper Motor The following table shows the stepper motor specifications: Table ‎2-1: Stepper Motor Specifications Current 4.2 A Angle 1.8° Torque 8.34 N.m The desired torque calculated to withstand the mirror…

Maintenance of recreational vehicles What is an RV? The word RV stands for “Recreational Vehicles”. This is a new, entirely different and a revolution in the generation of vehicles and automobiles. These are described as such vehicles that have all the features and facilities of home. They have quite a large living space, equipped with all the necessary items of home like kitchen, bathroom, bedroom, dining room, lounge equipped with all basic facilities like TV, light, fan, sofa or a desk,…

Chapter-III OPERATING PRINIPLE AND LOSSES IN PEM FUEL CELL The polymer membrane is the heart of the PEM fuel cell which has some unique features. It allows protons but it is impermeable to gases, and hence it is known as a Proton Exchange Membrane. The membrane, which is squeezed between two electrodes (electrically conductive carbon cloths or carbon fiber papers) acts as electrolyte. A layer of catalyst particles (platinum) is placed at the interface between the porous electrode and polymer…

Nowadays, most of the developing countries aim to improve their public transportation services so as to reduce traffic congestion and face the increased private cars ownership. Many systems have been proposed to improve the level of service of public transit. One of these systems is the Bus Rapid Transit (BRT) which combines the exclusive right of way, speed and reliability of railways and the flexibility and cost saving of buses. A number of cities use road lanes that are fully dedicated to…

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…

The Origins of Electric Guitar By: Pierce Bradley The electric guitar, an invention that’s not even a century old yet that has an intrinsic role in the history of music, especially the last 40 to 50 years having turned the guitar into an iconic figurehead and institution for musicians old and new. An though the electric guitar is less than a hundred years old it has ancestry in older, classical acoustic instruments built as early as 1779. The first electric guitar was dated in 1931. It’s a…
