In addition to the building properties effect on energy consumption, it is important to consider occupant’s energy behavior and their interaction with building systems in energy calculations. According to studies, energy retrofit regardless of considering this factor, has a lower effect on reducing the energy consumption. This study investigates the impact of energy retrofit in two (retrofitted...
multi-path is favorite alternative for sensor networks, as it provides an easy mechanism to distributetraffic, as well as considerate fault tolerance. in this paper, a new clustering based multi path routingprotocol namely ecrr (energy efficient cluster based routing algorithm for improving reliability) isproposed, which is a new routing algorithm and guarantees the achievement to required qos ...

in the last quarter of the century, a substantial amount of research work has been conducted on optimization of energy consumption by refrigeration systems and on proper design and construction of household refrigerator-freezers. the importance of such energy optimization schemes stems from the environmental impacts of freon (r-12) used as the working refrigerant in household refrigerator – fre...
The present study draws attention to increasing energy efficiency in private households enabled by systematic integration of end consumers by using an innovative interface. The object of investigation is referred to technical and social requirements towards a consumer interface to present energy consumption. As the success of interfaces is a question of consumer-friendly design it was questione...
train energy saving problem investigates how to control train's velocity such that the quantity of energy consumption is minimized and some system constraints are satis ed. on the assumption that the train's weights on different links are estimated by fuzzy variables when making the train scheduling strategy, we study the fuzzy train energy saving problem. first, we propose a fuzzy energy ...
Abstract. Considering the need to save energy consumption in less developed countries, it seems necessary to identify the effective factors of energy growth in the economy of OPEC countries. Energy intensity represents the energy required to produce a unit of product at the national level. Energy intensity at the level of an industry or a specific production process is calculated in terms of ph...
gas motion within the cylinder is one of the major factors that control the combustion process in spark ignition engine. it also has significant impact on heat transfer. both the bulk gas motion and the turbulence characteristics of the flow are important and governing the overall behavior of the flow. an arrangement for obtaining a stratified charge, using port injection, is proposed for a cur...
