The focus on the braking phase, especially recuperation that offers highest saving potential.Energetic was carried out as a part current railway reconstruction study, which good example possible energetic calculation use. Energetic are p...

Recently, wireless sensor network (WSN) is the popular scope of research. It uses too many applications such as military and non-military. WSN is a base of the Internet of Things (IoT), pervasive computing. It consists of many nodes which are deployed in a specific filed for sense and forward data to the destination node. Routing in WSN is a very important issue because of the limitation of the...

One of the important issue in MANETs is an energy saving and security. Each node in MANETs has limited energy resource, so that the lifetime of the network is one of the major critical issues. This paper studied SVM data aggregation method for classifying nodes according to their threshold values, this method eliminated the data redundancy and outliers but classification method is not much enou...

from 60 decade  sustainability issues  and sustainable developing  have opened a way in scientific meetings associated with  environment and urbanization and architecture. sustainability goals are improving of environment situation , less pollution  and at least interference on  land and interaction of  natural and artificial environment , that most of these cases attracted attention in archite...

Fuel wood provides the main source of energy for cooking and space heating for over 80 percent of households living in Kenya. The heavy reliance on the biomass energy has exerted an imbalance in demand and supply consequently resulting in adverse environmental effects in Kenya. As part of innovation efforts, several energy-conserving technologies have been developed. A unique cook stove named M...

Cloud computing is becoming an important opportunities for industry to provide a high degree of scalability and serviceability of computing resources. In order to integrate the system resource, utilize the resource flexibly, save the energy consumption, and meet the requirements of users in the cloud computing environment, one of the positive solutions is to apply the virtualization technology....

The exergy analysis is a proper method for performance evaluation of industrial systems. A generic and detailed analysis of the GPCSs on the second gas pipeline of Iran  is made by the means of exergy. The two main improvement measures of fuel pre-heating and steam injection technologies are presented for the current conventional stations. Steady state equations regarding the second law of ther...
