Abstract—In this paper, the diagnosis of soft faults in lossy electric transmission lines is studied through the inverse scattering approach. The considered soft faults are modeled as continuous spatial variations of distributed characteristic parameters of transmission lines. The diagnosis of such faults from reflection and transmission coefficients measured at the ends of a line can be formul...

An efficient transient analysis of lossy lines with nonlinear loads requires the ability to compute and represent a suitable set of line impulse responses. In this paper, we propose the evaluation of the matched-line impulse responses by means of an algorithm for the numerical inversion of the Laplace Transform. Based on a discussion of the structure of the impulse responses, we demonstrate how...

in this paper power system model is represented in a new domain that relates to multi-resolution analysis (mra) space. by developing mathematical model of elements in this space using galerkin method, a new alternative method for power system simulation in nonsinusoidal and periodic conditions is developed. the mathematical formulation and characteristics of new proposed space is expressed. als...

The series-connected lossy Josephson transmission line (JTL), constructed basically from junctions, capacitors, and resistors, is considered. continuum approximation equation describing the JTL derived. From latter, equations pump, signal, idler interaction are derived, thresholds for parametric amplification calculated.

Spatial moisture distribution in natural soil or other material is a valuably information for many applications. Standard measurement techniques give only mean or punctual results. Therefore a new inversion algorithm has been developed to derive moisture profiles along single TDR sensor-probes. The algorithm uses the full information content of TDR reflection data measured from one or both side...

In this paper, we propose an adaptive priority-based selective repeat ARQ (PSR-ARQ) transmission scheme for transmitting video over a single-hop lossy wireless link. If transmission errors occur in a lower layer of the video, the errors propagate to all the higher layers of related frames resulting in significant degradation of the video quality at the receiver. Due to the limited channel bandw...

Since past investigations have shown that radio frequency (RF) signal transmission in the bore of a railgun can be practical, the feasibility of using time domain reflectometry and well-established transmission line theory is investigated as a means to determine armature position during launch. This report describes the transmission line model of the HEMCL and initial measurements suggesting th...

A new, comprehensive CAD-oriented modeling methodology for single and coupled interconnects on an Si–SiO2 substrate is presented. The modeling technique uses a modified quasi-static spectral domain electromagnetic analysis which takes into account the skin effect in the semiconducting substrate. equivalent-circuit models with only ideal lumped elements, representing the broadband characteristic...
