Biological Low-Voltage Scanning Electron Microscopy. Edited by Heide Schatten and James B. Pawley. Springer Science+Business Media, LLC, New York; 2008, 317 pages. ISBN 978-0-387-72970-1; e-ISBN 978-0-387-72972-5 - Volume 15 Issue 6
A new circuit configuration for the generation of both reactive power and harmonic current is presented. Unlike Thyristor Controlled Reactors (TCR), the voltage across an inductor is pulse–width modulated in such a way to produce the required line current. In this presentation the switched inductor is producing laggin…
This paper describes a deep trench module development for a Smart Power Technology by introducing a lateral dielectric isolation. The approach to introduce the new isolation type in a modular way has impact on the process development and the layout environment. The work describes the advantages and the limitations of…
This report details the chemical and radionuclide contaminant results for the characterization of the 2009 First Quarter sampling of Tank 50 for the Saltstone Waste Acceptance Criteria (WAC). Information from this characterization will be used by Liquid Waste Operations (LWO) to support the transfer of low-level aqueo…
Abstract Semiempirical, ab initio, and density functional theory (DFT) studies were conducted on a homologous series of straight chain perfluoroalkyl carboxylic acids (PFCAs) ranging in chain length from C~1~ (trifluoroacetic acid; TFA) to C~9~ (perfluorodecanoic acid). Regardless of perfluoroalkyl chain length and co…

The resonant tunneling phenomenon is well understood in quantum mechanics. We argue why a similar phenomenon must be present in quantum field theory. We then use the functional Schrödinger method to show how resonant tunneling through multiple barriers takes place in quantum field theory with a single scalar field. We…
The growing need for clean air has prompted automobile manufacturers to invest large amount of time and money to control the emission from the automobile. The use of catalytic converter is one of the popular methods to control the emission from the vehicle. The catalytic converters are active only after reaching the ‘…
It is no news that the automotive engineering body has been challenged to design vehicle body-in-whites (BIW) to accommodate passive and active safety systems, include functional attributes such as panorama windows, facilitate passenger access, increase loading and fuel capacity, comfort and NVH, quality and cost-bene…
Abstract The behavior of oxide scales on Fe‐20Cr alloy was investigated in constant load at 1173 K in air. The objective was to understand the effect of mechanical loading on the deformation of oxide scales. It was carried out mainly by comparison of surface morphologies of oxidized specimens observed by scanning elec…

The introduction of nuclear power is a challenging, time-consuming and complex endeavor. After lengthy deliberations and research, some discover they are not prepared to take on the responsibilities or make the necessary investments to pursue nuclear power at this time. In particular, as countries begin to study their…
Power losses and voltage stresses are a problem in active filters. This paper proposes a voltage-source active filter (VSAF) with an LCLC-circuit which has lower voltage stresses, smaller power losses and smaller inductors than a conventional VSAF. The method is based on the series capacitor structure used to block th…
Exhaust pollutants of diesel engines have to be drastically reduced. The oxides of nitrogen (NOx) and particulate matter (PM) form the main challenge for diesel exhaust cleaning. The fuel economy of the engines must also be kept at an adequate level to prevent the increase in CO2 emissions and operational costs. For d…
A dismantlable (=dismantle-able) adhesion method using electromagnetic induction heating (IH) and thermoplastic adhesive has been proposed. The feature of this method is easily able to bond and dismantle in many times. In conventional interior works, a circle type induction coil is applied. But this coil is ineffectiv…
In addition to the IEEE Standard Test Procedure for Induction Motors (IM), several advanced methods have been presented to achieve higher accuracy on parameters estimation. Some of them allow to estimate with high precision only a specific parameter, while others improve the parameters estimation at the price of high…
Steam-generating sheets for disposable body warmers were prepared using techniques in papermaking processes, from slurries of iron powder, fibrillated cellulose fiber, and activated carbon powder with various weight ratios. Heat generation behavior of the composite sheets was compared with mat-formed samples. Composit…
In the title centrosymmetric binuclear complex, [Cd(2)(NO(2))(4)(C(11)H(9)N(5))(2)], the unique Cd(II) ion is in a distorted dodeca-hedral CdN(3)O(5) coordination environment. The two inversion-related Cd(II) ions are separated by 3.9920 (6) Å and are bridged by two O atoms from two nitrite ligands. There are two type…
Shunt Active Power Filters (APF's) are becoming an important consideration for installations where a large number of non-linear loads are responsible for failure to comply with standards for harmonic distortion of the current waveform [16, 17]. This paper is concerned with a control strategy for a voltage-fed shunt AP…
In this paper, the field of the permanent magnets of a PM machine is investigated. The focus is to calculate the field and its fourier components analytically depending on two main factors for machine design: magnet width (in circumferential direction) and magnet skewing. Skewing in a limited number of steps is regard…
