Elevated inflammation has been repeatedly observed in posttraumatic stress disorder (PTSD), and it may drive the development of both psychiatric symptoms and physical comorbidities. However, it is not clear if elevated inflammation is a feature of both remitted and current PTSD, and little is known about relationships between specific clusters of PTSD symptoms and inflammation. Exaggerated threat...
With growing electricity demand and environmental concerns, renewable energy especially wind energy has been moved into the center of concentration recently. The wind energy conversion (WECS) system has connected to the power grid to provide the consumer electricity demand. The various area where researchers have underwritten could be classified in various methods. The main unease of many previous...
Modeling and modifying wind energy conversion systems are becoming extremely attractive topics for scientists and engineers around the world. Assessing the potential of wind as a basic and indispensable part of wind farm establishment is also taken into consideration by many researchers. In this paper, we study the wind energy potentiality of Butterworth, Malaysia by comparing the wind power density...
Considering the increasing rate of energy consumption, dramatic lack of energy sources and approaching energy crises in the world the increase in the efficiency of electrical appliances and using renewable energy has recently become indisputable part of new technologies. Consequently, in this article an attempt will be made to introduce a new and simple method to increase the efficiency of On-site...
Nowadays researchers all around the world are looking for alternative option for fossil energy resources by renewable and sustainable energies. Wind energy as one of the cheapest and sustainable energy sources has drawn attentions among energy decision makers and researchers. In this paper, we studied the wind energy potentiality of the Kuala Terengganu, Malaysia by means of statistical analysis of...
Attitude control of a satellite is performed by controlling two main parameters, angular speed and altitude. An inappropriate value for each of these parameters can lead the satellite to be lost in space or fall to the earth. This paper presents altitude and speed control of geostationary satellites by means of two controllers, the first one is a PID controller for regulating the altitude and the...
In this paper a boundary model is defined to assess the power quality and loading cost function of power systems. Each bus is assigned a position in the space state model that is calculated using a simple equation. The state space representation of buses in the boundary model facilitates analysis of power system including the effects disturbances, linear and nonlinear loading, as well as reactive...
