Information and Communication technology (ICT) takes the main role in the economic growth of a country and has many applications such as mobile network, healthcare, navigation system, internet, weather forecasting and home automation. Healthcare devices manufacture incorporate ICT components in their product for remote monitoring and delivering health associated services. Due to this additional...
Modern technological solutions in electrical applications require, above all, high energy efficiency. This means that such applications, materials with the highest possible conductivity should be used for conductive elements. Of all metals, copper is natural choice. Copper cables or wires networks and installations provide better thermal guarantee reliability - which translates into quality of ...
Abstract Cables headed with crimped lugs are frequently used in test laboratories temperature rise tests carried out to validate electrical devices. The increase the resistance of connections can cause high dissipation power and heat during these tests, impairing their outcome. This work evaluates effect thermal stresses on dissipated connections. was found be more sensitive than mechanical one...
Introduction The Riata and Riata ST implantable cardioverter-defibrillator (ICD) leads, a narrow caliber silicone lead without an outer jacket, have been shown to be prone to structural and electrical failure. While much interest has been shown in potentially lethal high-voltage (HV) failures caused by electrical short circuits due to a breach in the ethylene tetrafluoroethylene (ETFE) insulati...
We propose a planning method for offshore wind farm electrical collector system (OWF-ECS) with double-sided ring topology meeting the “N-1” criterion on cable faults, in which submarine cables layout of OWF is optimized considering length and power losses. The proposed mixed-integer quadratic programming (MIQP) model based Capacitated Vehicle Routing Problem (CVRP) formulation network expansion...
Electrical grid layout optimization should consider the placements of turbines and substations include effects such as wake losses, power losses in cables, availability different cable types, reliability-based operational/decommissioning cost besides initial investment cost. Hence, optimizing levelized energy is beneficial capturing long-term effects. The main contribution this review paper to ...
Protective relays work in concert with sensing and control devices to accomplish their function. Under normal power system operation, a protective relay remains idle and serves no active function. But when fault or undesirable condition arrives Relay must be operated and function correctly. A Power System consists of various electrical components like Generator, transformers, transmission l...
Introduction: Opiates cause dependency via affect on central nervous system. Locus coeruleus nucleus is a main group of noradrenergic neurons in the brain that plays an important role in the expression of opioid withdrawal signs. During opioid withdrawal, brain waves change in addition to physical and behavioral signs. In this study, we examined the effects of locus coeruleus electrical sti...
Subsurface power grids constitute one of the largest copper stocks in many industrialized cities. Over time, parts and zones of these systems have been continuously disconnected and abandoned, resulting in the emergence of urban infrastructure ores. This study aims to assess how current conditions and practices influence economic and environmental motives of cable recovery from such power grids...
