The short story “In a Grove” written by a brilliant Japanese writer Ryunasuke Akutagawa, brings into question the certainty of human knowledge and the tendency to lie by illustrating a balance between illusion and reality. The story is a series of testimonials about a murder. However, Akutagawa does not necessarily provide us with enough distinction between the truths and lies. What he did, was present us with enough information to leave us pondering on what events really occurred. According to…

In these applications, the three-level inverters often need to operate with modulation indices (m) lower than 0.5 [6]- [10]. Additionally, at lower modulation indices, traction drives operating with induction motors (IMs), interior permanent magnet motors (IPMs) or synchronous reluctance motors (SynRMs) may need to provide higher reactive power, thus operating with a lower power factor (pf) [9], [11]- [17]. For example, in [9], the power factor of IPMSMs at 0.2 modulation index is shown to be…

introduction of lower frequency harmonics in the spectrum increase current THD which may heat up the motor and the magnet. Thus, in the future study, hardware validation will be done to test the impact of the proposed strategy on the SUMO MD drive system, and an operating region would be defined in which the strategy can be used without any appreciable effect on the motor.

Rotor and touchdown bearing models Fig. 1 features the case study of the high-speed rotor. The photo was taken after manufacturing of the electric motor part, when the rotor was carried to the laboratory for an experimental modal analysis. During normal operation, the rotor is supported by AMBs. In the dropdown event, the rotor is in contact with touchdown bearings at both ends of the rotor. Fig. 1. Rotor under investigation. In this work, the finite element model of the rotor employs…

Title Mark Dowie’s opinion on this concept is that no profit is worth more than a human life. In his article he talks in depth about Ford Motor companies and a car they designed and produced in the seventies, the Pinto. The Pinto was a very rushed project that focused more on making a profit than the quality and safety of the vehicle. The entire tone of the article casts a harsh judgmental light on the decisions made during that project. He makes it very obvious that he opposes Ford decisions…

Tesla at current Tesla right now has sold 10,500 cars in the first half of 2013 and is expected to sell more next year. Total revenues are 560 million and net income is more than 10 million dollars. These are numbers that will continue to grow to take up more and more market and BMW needs to fully understand how Tesla is now in this position. It is very important that BMW understands both from a strategic viewpoint and execution viewpoint, how to best counteract this sudden rise in a…

Tesla Model S Sedan: An example of ad Project Management (Disclaimer, I am a huge fan of the Tesla product line) Elon Musk, CEO of Tesla Motors, has put together something no one previously thought was possible. An electric car that is practical and luxurious. Tesla sales have increased, 52% in Q2 2015 and are expected to continue to rise as more people become fed up with the oil industry and want to make a positive impact on the environment. Additionally Tesla cars have scored the highest…

Children develop at unique rates. The child for this paper is three years old and lives with both of her parents. The goal of this paper will be to approximate her development. There are many aspects of development; this paper will be focusing on Erickson’s psychosocial stages, Piaget’s stage theory, and her level of physical development. This particular child lives with both of her parents. The subject is three years old and is an only child. The subject is with her mother the most; the mother…

Augmenting Motor Skill Acquisition In an attempt to describe the augmentation of motor skill acquisition I am going refer to the work of Schmidt and Lee (2014) throughout this assignment and inform my comments around a skill used in basketball; the free throw. A free throw is a skill that is generally unaffected by environmental factors, such as opposition. This results in a stable and highly predictable environment throughout performance. These characteristics of a free throw describe a closed…

If you are like most people in the business world you have closely followed General Motors (GM). GM has many issues that face it today. Some of those issues are; Toyota has outsold Chevy in several previous months, lack of sales has led to increased inventory levels, a very complicated bureaucracy, very low profits, issues in their European market, and most recently a large amount of recalls on the automobiles they did sell. If you look at all of these problems individually, the causes are…
