In this paper, we present mathematical analyses to consider the effect of material properties on the sensitivity of the Microelectromechanical systems (MEMS) piezoelectric hydrophone and improve the sensitivity by choosing the proper material. The selected structure in the present paper is a piezoelectric hydrophone able to work at low frequencies. The piezoelectric hydrophones are widely used ...
There is cause and effect relationship between increase in load due to increasing penetration of electric vehicles (EV) load that causes unbalanced conditions and affect the power quality such as voltage degradation and even damage the equipment if the system is not properly managed. This paper presents detailed review of energy supply and management in conjunction with load synchronization thr...
anxiety disorders are the most common reasons for referring to specialized clinics. if the response to stress changed, anxiety can be greatly controlled. the most obvious effect of stress occurs on circulatory system especially through sweating. the electrical conductivity of skin or in other words galvanic skin response (gsr) which is dependent on stress level is used; beside this parameter pe...
the industrial growth of any developing country largely depends on the availability of abundant energy resources. according to the energy survey carried out by international atomic energy agency, (1) the contribution which nuclear energy will make towards the total energy requirements of the developed countries of the world by the end of the century will be about 50%. in iran by the year 1992 t...
have the potential to reduce their maximum peak dmand charges without sign$imntly afecting production. Working toward greater electrical tlCficiency will not only reduce your plant’s power costs but will also help your electric utility provide more efficient serdce at lower rates. This Technology Update helps you identijij whether your plant has the potential for reducing maximum demand and des...
adsorption of cyanogen molecule on the surface of pristine and sc-doped b12n12 nanocage is scrutinized using at dft calculations to investigating its potential as chemical nanosensors. the results show that cyanogen is weakly adsorbed on the pristine b12n12 and consequently its electrical properties are changed insignificantly. in order to improve the properties of the nanocage sensor, sc dopin...
In this study, a micro-CHP system using a gas internal combustion engine with a maximum power of 5 kW of thermal and electricity energy has been designed and fabricated. This system will be able to resolve the consumption of heat and electrical energy for single households. The operation of micro CHP system results indicated that the efficiency of the system was increased about 70% as compared ...
This paper has reported on the electrical and nonstructural of polymer-based materials in corporation NiO (Nickel oxide) in concentrations of 0.2%, 0.4% and 0.8% by weight of PVA (polyvinyl alcohol) polymer. Nanocrystallites phases and properties were characterized with using X-ray diffraction (XRD), Fourier transfer infrared radiation (FTIR),Energy distribution X-ray(EDX) techniques and X-Map ...
In recent years, using new methods in utilization of energy resources has become necessary due to environmental pollution and restriction of energy resources. The hybrid system presented in this article produced power with SOFC and Stirling engine. The purpose is to analyze a 50 kW Solid Oxide Fuel Cell that could produce enough thermal energy for a 10 kW Stirling engine working in the hybrid s...
