Modeling and design of on-chip interconnect continue to be a fundamental roadblock for high-speed electronics. The continuous scaling devices interconnects generates self mutual inductances, resulting in generating second-order dynamical systems. model order reduction is an essential part any modern computer-aided tool prefabrication verification the components interconnects. existing methods u...
one of the most commonly used techniques to reduce the corrosion rate of rebar in concrete is addition substances named corrosion inhibitors into the concrete. corrosion inhibitor is chemical compounds that were added to concrete to prevent corrosion of steel in concrete. sodium nitrate is a type of anodic inhibitors that this study investigatesthe effect of this inhibitor on the properties of ...
this thesis attempts to measure learning styles, self efficacy and intrinsic motivation as predictors of iranian ielts reading comprehension. in order to address this issue, a quantitative study was conducted on some randomly selected intact students at ferdowsi university. these two groups were assigned as they were undergraduate (ba=91) and graduate (ma =74) students; they were all aged betwe...
the main purpose of this study was to investigate any relationship between high school efl teachers metaphorical understandings of their role in class and their self-efficacy beliefs. teachers metaphors were elicited through two different prompts: one picturing what they believed a language teacher should be like in class, and the other demonstrating what they are actually like in class; such...
Abstract This Review examines methods to model Josephson devices such as arrays of superconducting quantum interference (SQUIDs) and rows within two-dimensional filters or SQIFs. The emphasis is on high temperature (HTS) devices, though the techniques apply for any operating temperature. use freely-available proven software first extract all self mutual inductances thin-film device, then incorp...
The paper is focused on the optimization of compensation network a wireless power transfer system (WPTS) intended to operate in dynamic conditions. A laboratory prototype WPTS has been taken as reference this work, allowing for experimental data and all numerical models here presented reproduce configuration existing device. model used perform FEM analysis with variable relative positions emitt...
An inductance calculation method, which is based on calculating the current distribution of a fluxoid-trapped superconducting loop by using the expression of momentum and the Maxwell equations, is reconstructed to enable calculation of arbitrary 3D structures which have a ground plane (GP). Calculation of the mutual inductances of the superconductor system is also incorporated into the algorith...
The air-cored resonant induction machine removes the magnetic core, so fields produced by windings are truly 3-D in nature. end-windings normally regarded as a nonactive and leakage source conventional iron-cored machines now become an active part contribute to torque production. Therefore, electromagnetic modeling can no longer be reduced 2-D analysis, inductance calculation becomes key proble...
The leakage field in shell-type transformers is strongly affected by the boundary conditions introduced core walls and thus effect of should be considered properly inductance calculation. In this paper, a new method for accurate calculation multi core-segment with circular windings presented. For purpose, first, expressions self mutual inductances are derived cylindrical coordinates considering...
The article discusses the selection of cables for power lines connecting wind turbine generators at plant. screen cross-section these should be selected considering value current double line-to-earth fault. To calculate this current, dimensions cable known. However, parameters are hidden and cannot used during designing. Therefore, a highly simplified method is currently in practice. It shown t...
