The development of different forms of measurement models for impedance has allowed examination of key assumptions on which the use of such models to assess error structure are based. The stochastic error structures obtained using the transfer-function and Voigt measurement models were identical, even when non-stationary phenomena caused some of the data to be inconsistent with the Kramers–Kroni...

In this paper a novel method for computing the radiation pattern and also the input impedance of a planar rectangular micro-strip antenna array with consideration of mutual coupling and mutual impedance is presented. Each two triangles with a common edge make an Edge element or RWG. Any such edge element is considered as an infinitesimal dipole. The electrical currents over each dipole can be c...

The purpose of this study is to provide a new approach for detection using bio-impedance. This impedance is measured by the four-electrode method. As the impedance changes resulting from ankle, knee, and hip movements depended heavily on electrode placement, we determined the optimal electrode configurations for those movements by searching for high correlation coefficients, large impedance cha...

BACKGROUND Intrathoracic impedance-derived OptiVol fluid index calculated using implanted devices has been shown to predict mortality; direct measurements of impedance have not been examined. We hypothesized that baseline measured impedance predicts all-cause mortality; changes in measured impedance result in a change in the predicted mortality; and the prognostic value of measured impedance is...

microgrid presents an efficient and novel solution for integrating many new energy generating resources with traditional distribution networks. having an appropriate protective scheme is a fundamental challenge in achieving microgrid plans. it is proven that traditional protective plans are not efficient for protecting microgrid, since the network is dynamic and the level of fault current chang...

Abstract The integrated study of seismic attributes and inversion analysis can provide a better understanding for predicting the hydrocarbon-bearing zones even in extreme heterogeneous reservoirs. This aims to delineate characterize gas saturated zone within reservoir (Cretaceous C-sand) interval Sawan field, Middle Indus Basin, Pakistan. hydrocarbon bearing is well identified through attribute...

A transceiver for a 25.8 Gbps/lane with a re-timer IC has been developed for information and communication equipment. Since a 1-unit interval (UI) is very narrow at 38.8 ps at 25.8 Gbps, power integrity (PI) jitter due to power supply fluctuation cannot be ignored. In this paper, we proposed a decoupling-capacitors (Decaps) placement technique to reduce power distribution network impedance (Zpd...

A 4-interval forced-choice procedure was used to determine the detection threshold for electric shock in psychopathic and nonpsychopathic criminals. The use of a constant-current stimulator, a concentric electrode, and monitoring of the skin-electrode impedance permitted precise control over the characteristics of shock administered. The results indicated that the psychopathic Ss had a signific...

High throughput applications using broadband impedance spectroscopy as method for label free detection are limited by measurement speed and the enormous amount of raw data. Although often ignored, the fastest method for determining the passive electrical properties is the processing of the answer after step excitation. Sampling with constant time interval is common but not feasible for real tim...
