Optimal Overcurrent Relay Coordination: A Review

Procedia Engineering, 2013
AbstractThis paper presents an overview on optimal overcurrent relay coordination in protection system and protective relays. Efforts have been made to include all methods used for the coordination of overcurrent relays. It includes techniques, such as Artificial Intelligence (AI) and Nature Inspire Algorithm (NIA) as well as other conventional methods

A Tac1‐Expressing Brainstem Pathway Underlies the Pathogenesis of Trigeminal Neuralgia

Advanced Science, EarlyView.
A critical TG‐Sp5CTac1‐PBNTac1 pathway drives trigeminal neuropathic pain (TNP). Tac1‐expressing parabrachial nucleus (PBNTac1) neurons exhibit heightened responses to innocuous stimuli in TNP, and chemogenetic inhibition of these neurons effectively prevents TNP development.

A Soft Robotic Model for Simulating Heart Valve Disease and Cardiac Interventions

Advanced Science, EarlyView.
This paper introduces a fully synthetic fabrication methodology for a soft robotic, in‐vitro model of the left‐heart, complete with a functioning mitral valve apparatus. With a view towards patient‐specific modeling, we demonstrate physiological flow and pressure waveforms, tunable mitral valve function with clinical imaging compatibility, and its use ...

Considering Pilot Protection in the Optimal Coordination of Distance and Directional Overcurrent Relays

Iranian Journal of Electrical and Electronic Engineering, 2015
The aim of the relay coordination is that protection systems detect and isolate the faulted part as fast and selective as possible. On the other hand, in order to reduce the fault clearing time, distance protection relays are usually equipped with pilot ...

OPTIMUM OVERCURRENT RELAY’S COORDINATION USING MULTIPLE STANDARD RELAYS CHARACTERISTICS

International Journal of Technical Research & Science
Relay Coordination is very crucial task as it required coordination of primary and backup relays. in past various authors have proposed modification in standard overcurrent relays characteristic, modification in objective function to achieve optimum results of operating time of primary as well as backup relays. In this paper, considering normal inverse,

Alternating High‐Fat and Polysaccharide Diets Modulates Gut Phage‐Bacterial Interplay

Advanced Science, EarlyView.
This study reveals how alternating high‐fat and polysaccharide diets reshape the human gut virome and enhance phage‐bacteria interactions. Using large‐scale metagenomic meta‐analysis and a time‐resolved mouse model, the authors show that diets strongly modulate phage abundance, lifestyle, and gene exchange, offering new insights into nutrition‐guided ...
