A sustainable development of world economy implies that industrial energy conservation is indispensable. Therefore, managerial aspects of industrial energy conservation need to be studied. In this article, a tool is described that enables to study the influence of sequential decision making on the design (choice of unit operations) and, consequently, on the specific energy consumption of a prod...

In sensor network, energy conservation is one of the most critical issues since sensor nodes should perform a sensing task for a long time (e.g., lasting a few years) but the battery of them cannot be replaced in most practical situations. For this purpose, numerous energy conservation schemes have been proposed and duty cycling scheme is considered the most suitable power conservation techniqu...

this paper investigates the relationship between total energy consumption and gdp in six countries of the middle east , including iran,pakistan,saudi arabia,oman,bahrain and the united arab emirates. the data are annual and spanning the period 1980-2012.we employed hsiao’s (1981) methodology to examine causality relation between total energy consumption and gdp.the empirical findings show a uni...

in this study, the optimal cropping patterns based on individual aims are presented and followed by a multi-objective cropping pattern with emphasize on the use of conservation tillage methods in darab region presented. individual goals consisted of maximizing gross margin and food secin this study, the optimal cropping patterns based on individual aims were presented and followed by using a mu...

In today’s World, ICT(Information communications technology)is growing with full swing for every small or large scale businesses and this has given a boost to the technology like “Cloud Computing”. In implementation, it is a very challenging technology in itself. Out of different challenges, energy conservation and security issues are the most demanding in cloud computing in the present scenari...

A complete and explicit classification of all independent local conservation laws of Maxwell’s equations in four dimensional Minkowski space is given. Besides the elementary linear conservation laws, and the well-known quadratic conservation laws associated to the conserved stress-energy and zilch tensors, there are also chiral quadratic conservation laws which are associated to a new conserved...

We discuss the work-kinetic energy theorem and the mechanical energy conservation theorem in the context of general physics courses. The motivation is the fact that all modern texts on introductory mechanics show the same conceptually dangerous statement that besides obliterating the concept of mechanical work, diminishing the importance of the work-kinetic energy theorem, leads to erroneous ap...

A number of studies have estimated how much energy conservation is achieved by providing households with real-time information on energy use via in-home displays. However, none of these studies tell us why real-time information changes energy-use behavior. We explore the causal mechanisms through which real-time information affects energy consumption by conducting a randomized-control trial wit...

Wireless Sensor Networks are gaining more and more importance in present era. Recent Advances in WSN have extended the applicability of these to wide range of real time applications. One of these recent advances in WSN is invention of Heterogeneous Wireless Sensor networks (HWSN). Compared to Homogenous, Heterogeneous have large curve of applicability. However, whether it is Homogenous WSN or H...
