Background: Recently, ultrasonic neuromodulation research has been an important and interesting issue. Ultrasonic neuromodulation is possible by the use of low-intensity transcranial focused ultrasound (tFUS) to stimulate or inhibit the neural structures. The primary capability of this method is the improvement in the treatment progress of certain neurological and psychiatric disorders noninvas...
structural, optical and electrical properties of silvernanoparticlesdeposited by spin coating method
in this study, silver nanoparticles were synthesized by chemical reduction method at different concentrations of ag colloid in the range of 500-16000 ppm. nanoparticles were deposited by spin coating method on pre-etched glass and si substrates. structural, optical and electrical properties of the samples were studied using scanning electron microscopy equipped with edax, uv-vis spectrophotomet...
Today, smart grids are one of the important topics in the field of electrical engineering. In this paper, after identifying the communication layers among the components of a smart home in the introduction, some of the most important communication protocols ruling will be abbreviately discussed over the smart homes. Then, applying the household electrical load management program by smart homes,...
Abstract General faults in regular electrical railways system could be detect by implementing the specific protection functions such as ground fault or sensitive earth fault. Otherwise, in ungrounded electrical railway systems which using both feeding and return contact rail at the same time, fault detection cannot done with above-mentioned function. Due to recent growth in electrical railway ...
abstract according to increase in electricity consumption in one hand and power systemsreliability importance in another , fault location detection techniqueshave beenrecentlytaken to consideration. an algorithm based on collected data from both transmission line endsproposed in this thesis. in order to reducecapacitance effects of transmission line, distributed parametersof transmission line...
Carbon nanostructures via adding to a polymer matrix, while improving the electrical, mechanical and optical properties of the nanocomposites, are widely used in the industry, medicine, and agriculture. The authors presented several investigations on a new type of gamma dosimeter based on the polymer-carbon nanostructures nanocomposite. In this research, the electrical percolation threshold of ...
Introduction: Electrocutions have a low frequency and severe consequences. The purpose of this study was to analyze the parameters related to electrical accidents, and evaluation of electrical safety performance of small-scale industries. Method: This study was conducted in 2019 on 232 small-scale industries. Electrical accidents over a 7-year period were studied. The tools used included elect...
using principle of minimum total potential energy approach in conjunction with rayleigh-ritz method, the electro-thermo-mechanical axial buckling behavior of piezoelectric polymeric cylindrical shell reinforced with double-walled boron-nitride nanotube (dwbnnt) is investigated. coupling between electrical and mechanical fields are considered according to a re...
in this research using the theory of induction motor (um), a um with liquid as secondary part is planned and manufactured. the main objective for planning of this motor is to investigate the possibility of chemical liquids pumping such as liquid poison and acids. results of many laboratory tests are shown to conclude that pumping force in the manufactured pump is dependent on many factors su...
Transcutaneous electrical nerve stimulation (TENS) is an analgesia inducing method with increasing applications in clinical procedures. In this study we tried to evaluate the role of the adrenergic system and its different adrenoceptor subtypes in TENS-induced analgesia. Two types of low and high frequency electrical stimuli were used in rats through needle electrodes, inserted at the base ...
