Due to the resource constraint and dynamic parameters, reducing energy consumption became the most important issues of wireless sensor networks topology design. All proposed hierarchy methods cluster a WSN in different cluster layers in one step of evolutionary algorithm usage with complicated parameters which may lead to reducing efficiency and performance. In fact, in WSNs topology, increasin...

this paper describes the application of process integration principles to the design of oil refineries hydrogen network. in this regard, a design hierarchy as well as heuristics and required guidelines are proposed. the recommended rules compensate lack of procedure to the design and make the design process easier. the guiding principles of the design are based upon pinch technology and extendi...

From a general perspective, urbanism can be assumed as a bipolar world. On one hand, large-scale plans formulated by official organizations are shaping urban environment and the entirety of our cities; on the other hand, social activists and artists, active in the field of cities, are making an effort to give it a human character. According to De Certo (1984), the first approach to city, adopte...

Climate change has become a challenge with adverse impacts on the Earth. Reducing the use of fossil fuel is a primary step to solve environmental problems. As the population continues to rise, to meet the growing demand for construction with a large share in energy Consumption, Efforts to make the built environment more energy efficient is crucial. The main objective of this research is to eval...

A model capable of simulating evaporators with multiple modules under frosting conditions was developed and validated. Effects of various geometrical parameters on fan and compressor power consumption were quantified and some general guidelines for design were developed. These general guidelines were used to design new prototypes for a given external load keeping in mind the packaging restricti...

This paper surveys the most promising low-power and energy-efficient asynchronous design techniques that can lead to substantial advantages over synchronous counterparts. Our discussions cover macro-architectural, micro-architectural, and circuit-level differences between asynchronous and synchronous implementations in a wide range of designs, applications, and domains including microprocessors...

Energy efficiency has a vital role to mitigate increased power consumption and carbon dioxide emissions. Future wireless communication systems should be designed in such a way that energy efficiency as an important design rule. Heterogeneous Networks (HetNets) have recently being considered as an effective approach to provide better cellular network coverage and capacity. In the proposed system...
