A mathematical model based on d-q axis theory and dynamic performance characteristic of brushless resolvers is discussed in this paper. The impact of rotor eccentricity on the accuracy of position in precise applications is investigated. In particular, the model takes the stator currents of brushless resolver into account. The proposed model is used to compute the dynamic and steady state e...

A study on the evaluating equivalent damping and response modification factors of frames equipped by Pall Friction Dampers is presented. To do so, buildings with various stories were considered. Nonlinear and linear dynamic time history analysis has been performed to evaluate equivalent damping for Pall Friction Dampers. Ground motions with various frequency characteristics scaled with Iranian ...

The goal of this paper is the experimental validation a gray-box equivalent modeling approach applied to microgrids. main objective represent dynamic response microgrid with simplified model. contribution work two-step process, composed by definition nonlinear model operational constraints, adapted environment, and identification procedure used define parameters. Once parameters are identified,...

The promotion of human welfare is undoubtedly one of the greatest challenges of economic development. To achieve this, many developing countries adopted trade liberalisation in the late 1980s, premised on the theoretical evidence based on the definitive Heckscher-Ohlin theory which predicts gains for the poor. The empirical support for this theory, however, is at best mixed. This paper employs ...

C photosensors principally consist of a zero or reverse biased photodiode connected to an amplifying transistor as shown in fig.1. Impinging photons generate electron-hole pairs in the photodiode which are separated due to the electric field in the space charge region of the pn-junction. The associated charge transport results in a signal dependent photocurrent iph = q/ t. The transistor either...

this paper presents a comprehensive case study on electro-mechanical analysis of mems[1] variable capacitors. using the fundamental mechanical and electrical equations, static and dynamic behaviors of the device are studied. the analysis is done for three different modes, namely: dc (static mode), small signal ac and large signal regime. a complete set of equations defining dynamic behavior of ...
