A reference standard for a unit of measurement is an artifact that embodies the quantity of interest in a way that ties its value to the reference base. The selection of an appropriate reference standard is a crucial point in the performance evaluation of wire rope electromagnetic testing (EMT) instrument. In this paper, a 3-D finite element model (FEM) has been developed to study three referen...

This paper is concerned with the existence of globally smooth solutions for the second boundary value problem for Monge-Ampere equations and the application to regularity of potentials in optimal transportation. The cost functions satisfy a weak form of our condition A3, under which we proved interior regularity in a recent paper with Xi-nan Ma. Consequently they include the quadratic cost func...

On any compact Kähler manifold, Mabuchi [16], Semmes [17], and Donaldson [5] introduced a Weil-Peterson type metric in the space of Kähler metrics and proved that it is a formally non-positively curved symmetric space of “noncompact” type. According to [17], the geodesic equation can be transformed into a homogenous complex Monge-Ampere equation. In [5], Donaldson proposed an ambitious program ...

This paper presents a detailed recent research trend on multi-phase induction machines, which include multiphase induction motor as well as the multiphase induction generator. Electrical power system developed so far was of three phases since the beginning of the last century but research in the field of multi-phase machines have attracted increased interest in recent years due to the several a...

High-power Free-Electron Lasers were made possible by advances in superconducting linacs operated in energy-recovery mode. In order to get to very high power levels, say a fraction of a megawatt average power, many technological barriers are yet to be broken. We describe work on CW, high-current and high-brightness electron beams. This will include descriptions of a superconductinglaser-photoca...

This paper is concerned with the employment of an autonomous and intelligent agent within the context of a 3-dimensional virtual environment. As the agent is immersed within the virtual environment, it empowers the 3D world with mechanisms to adjust itself to the specific needs of its user. Therefore, the agent serves as a middle layer between user and the environment. The 3-dimensional environ...

The Human Body Is Electricity Based. Electricity made inside the body cells, using low levels of electric currents at one-millionth of an Ampere –called a micro-current– provides power for the body. Injured cells resist the body's natural micro-current. This causes the natural micro-current to take the path of least resistance around the area of injury rather than through it. This prevents the ...

This study investigates the influence of buried magnet arrangement on efficiency and drivability performance provided by an on-board interior permanent synchronous machine for a four-wheel-drive electric car with two single-speed powertrains. The relevant motor characteristics, including flux-linkage, inductance, electromagnetic torque, iron loss, total efficiency, are analyzed set six configur...
