this present research work was carried out to evaluate the energy consumption in a typical iranian building based on the forecast of climatic variables. thus, the lars-wg model was validated for some northwest stations of iran, including tabriz, ardebil, oromieh, kermanshah, hamedan, sannandaj, qazvin, and zanjan. the average monthly outdoor temperature was forecasted from 2011 to 2100. the rel...

objective: the main objective pursued in this paper is to investigate the energy consumption for drying of potato slices using vacuum-infrared drying method. methods: drying of potato slices with the thicknesses of 1, 2 and 3 mm were conducted at vacuum levels of zero (without vacuum), 20, 80 and 140 mm [hg], infrared radiation at power levels of 100, 150 and 200 w in the three repetition. resu...

the municipality of tehran is intending to construct a permanent international flower exhibition. the activities for construction began in the year 2006. the exhibition has three distinct areas namely “northern area”,”southern area” and “central area”. in northern and southern area the flowers are supposed to be preserved and in central area, they will be sold out. in the present st...

due to shortage of precipitation and the spatial and periodical disparity of rainfalls, iran iscounted among the arid and semi-arid countries of the world, and therefore the water utilities have put thecontrol of consumption and efficient use of water high on their priorities. water consumption management isconsidered as a field of energy management, and the impacts of effective measure related...

Clustering is an effective technique that can greatly contribute to overall system scalability, lifetime, and energy efficiency in wireless sensor networks (WSNs). In this paper, we propose an energy efficient clustering algorithm for WSNs based on the LEACH algorithm. LEACH (Low Energy Adaptive Clustering Hierarchy) is one of the most well known energy efficient clustering algorithms for WSNs....

Data transfer is an indispensable step that is widely involved in the maintenance and processing of Cloud data. Due to rapid growth in Cloud data, methods of reducing the huge energy consumption of data transfer in the Cloud have become a challenge. In this paper, we propose a novel energy-efficient data transfer strategy called LRCDT (Link Rate Controlled Data Transfer). By scheduling bandwidt...

Unsupervised competitive learning algorithms for clustering of sensor nodes in wireless sensor networks are evaluated with a large scale data set in this paper. The Centroid Neural Network (CNN) is compared with Fuzzy c-Means (FCM) algorithm in determining cluster heads among given sensor nodes. The cluster heads are combined with Low Energy Adaptive Clustering Hierarchy (LEACH) for minimizing ...

In WSN, data aggregation is an important process for reducing the energy consumption. We can reduce energy consumption by using the efficient technique for data aggregation. Also, achieving the reliability and robustness of transferring data is one of the major issues and challenges. in order to produce both reliability and energy efficiency, in this paper we propose to design a Mobile Sink for...

A mobile ad hoc network is a self organizing temporary network. It consists of mobile nodes roaming here and there. Routing in such networks is a challenging task. Various routing protocols have been proposed since the origin of MANETS. DSR is the most popular routing protocol based on source routing. This paper is an extensive study of DSR taking various performance parameters. Effect of these...
