Increasing concerns about energy and emissions from fuel consumption in gas turbines has attracted many researchers to protect the environment and reduce pollutants in the world. The main objective of this paper is to investigate the increasing efficiency of three-stroke gas turbine operation based on the technical analysis of the operation of three-axis gas turbine cycles with non-design condi...

Mobile communication is more vulnerable to security attacks such as interception and unauthorized access than xed network communication. To overcome these problems, many protocols have been proposed to provide a secure channel between a mobile station and a base station. However, the public-key based protocols are not fully utilized due to the poor computing power and the small battery capacity...

Iran’s environmental condition is critical, since it is experiencing desertification, unsustainable development and overpopulation. The objective of this study is power source replacement in natural gas stations that operate with natural gas compressors, through using electrical motors, which can be fed by a 160 MW geothermal power plant, as an alternative to gas turbines. Application of such a...

Standing on the south bank of Thames, today, its chimneys reconstructed, brickwork restored, roof replaced, Battersea Power Station betrays few troubles that plagued development and redevelopment (Figure 1). Like many London’s power stations, began as two separate units: A, western wing, opened in 1933, B, eastern 1955. Unlike these other however, which ‘B’ building formed an ad hoc response to...

The Information and Communication Technology sector consumes approximately 3% of the world’s electrical energy due to exploding demand for internet service. most energy-intensive part cellular communications is base station, which there are about four million them deployed globally. As Fifth Generation (5G) wireless networks introduced, number stations will be growing in parallel with data traf...

The growing awareness towards energy efficient cellular networks has paved way for new technologies in designing green cellular networks. According to technical analysts, the base stations are the most energy intensive part of a typical cellular network. Saving power in base stations is therefore the primary focus in green cellular networks. The main goal of designing green base stations is for...

Multivariable regression and artificial neural network procedures were used to modeling of the input power and gas holdup of flotation. The stepwise nonlinear equations have shown greater accuracy than linear ones where they can predict input power, and gas holdup with the correlation coefficients of 0.79 thereby 0.51 in the linear, and R2=0.88 versus 0.52 in the non linear, respectively. ...

in this paper by using concepts of graph theory, forces method and substructure ing method for analysis of structures, some methods have been introduced for optimal analysis of structures in a large scale, using substructuring method. planar rigid frames assuming linear behavior and small deformations, have been optimal analyzed, by using forces method. thus, a fortran power station computation...
