Automated model-based transmission line fault location method using reduced equivalent circuit [PDF]

open access: yes, 2019
Transmission lines are a vital part of power systems and are prone to a variety of short-circuit faults. Transmission line faults must be accurately identified and cleared so as to restore the faulted line back to normal operation in the shortest amount ...

ACCURACY ESTIMATES OF THE FAULT LOCATION METHODS OF ARTIFICIAL TRANSMISSION SHORT CIRCUIT LINE 220-330 KV

open access: yesВестник Северо-Кавказского федерального университета, 2022
To determine the place of damage (OMP) on power lines (transmission lines) are used fixing devices (FP) and having the function of OMP emergency event recorders (RAS) and microprocessor protection terminals. The analysis of accuracy of WMD devices for 2017 presented in the article revealed an unacceptable error in 87 cases out of 1415 actuations.

Antenna representation in two-port network scattering parameter [PDF]

open access: yes, 2011
This paper proposes a representation of antenna in two-port network s-parameter, by exploiting the analogy between the antenna and a two-port network, to produce a suitable method for evaluating antennas in system and circuit simulation.

Functional and Structural Evidence of Neurofluid Circuit Aberrations in Huntington Disease

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Disrupted neurofluid regulation may contribute to neurodegeneration in Huntington disease (HD). Because neurofluid pathways influence waste clearance, inflammation, and the distribution of central nervous system (CNS)–delivered therapeutics, understanding their dysfunction is increasingly important as targeted treatments emerge.

Wavelet-Based High-Order Adaptive Modeling of Lossy Interconnects [PDF]

open access: yes, 2001
—This paper presents a numerical-modeling strategy for simulation of fast transients in lossy electrical interconnects. The proposed algorithm makes use of wavelet representations of voltages and currents along the structure, with the aim of reducing the

Effectiveness of rTMS on Working Memory and Inhibitory Impairments in Patients With Post‐Stroke Executive Deficits

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Considerable efforts have been dedicated to developing effective treatments for post‐stroke executive impairment (PSEI), among which repetitive transcranial magnetic stimulation (rTMS) has shown great potential. This study aimed to investigate the therapeutic effects of high‐frequency rTMS on working memory (WM) and response ...

A modified implementation of the Folded Line Equivalent transmission line model in the Alternative Transient Program

open access: yes, 2022
This paper proposes a modified implementation of the Folded Line Equivalent transmission line model to represent three-phase transmission lines. The Folded line equivalent decomposes a line into its open circuit and short circuit contributions.
