The importance of energy in the sustainable development of societies and its role in the economic, social and political relations of today's world is indisputable. The availability and proper use of energy resources ensures the full development of any country. Because of the importance of this issue, the topic of energy literacy was introduced in science education in the recent years. Textbooks...
The main aim of this paper is to evaluate the energy efficiency in 30 provinces of Iran by applying the different methods of DEA and Anderson and Peterson during the period of 2009-2013. Also, since classical analysis models do not differentiate efficient cases, the AP method (Anderson-Peterson) was used to rank efficient units for evaluating efficiency correctly. So that combination of input v...
With development of distributed generation in industrial microgrids (IMGs), the energy management program is used for optimal scheduling of production and consumption that reduced the operation cost. By restructuring in power systems and increasing energy prices in some hours of the day, more attention has been paid to the demand side management programs. In this paper a new model for controlla...
Necessity and importance of energy in state economic, social, and political structure and stability of and terminable fossil resources have been centerpiece of attention to energy issue in last few years. Urban railway, as one of the main pillars of urban economy, has increased the importance of this sector based on mass transit with advantages such as economic savings in fuel consumption, prev...
A critical need in wireless sensor networks is to achieve energy efficiency during routing as the sensor nodes have limited energy resources. The efficient energy consumption is the main issue in wireless sensor network. The efficient protocol should minimize the energy consumption. This paper presents a survey on energy efficient routing protocols in wireless sensor networks. Keywords— WSN, Ro...
the purpose of this study is to identify challenges of digital resources in academic libraries of kerman province. research methodology is descriptive- survey, a questionnaire is used for gathering data. research sample includes 41 librarians of kerman libraries and their managers. results show that economic challenges, in order, are: infrastructures and equipment purchasing, printed and digit...
The growing geographic disconnect between consumption of goods, the 26 extraction and processing of resources, and the environmental impacts associated with 27 production activities makes it crucial to factor global trade into sustainability assessments. 28 Using an empirically validated environmentally extended global trade model we examine the 29 relationship between two key resources underpi...
Aims: Increasing consumption of the earth's primary resources (materials and energy) in addition to the production of environmental and atmospheric pollutants (especially CO2), poses a serious threat to sustainable human life. The aim of this study was to evaluate the effect of using concrete, brick and wood in traditional construction in northwestern Iran on energy consumption and carbon emiss...
Backgrounds and Objectives:Today the crisis rising from over consumption energy and materialand environmental pollution pose serious problems that challenges present resources of man.Sustainable development is probably an inevitable strategy for human being in such a way that theleast possible damage be inflicted to the environment.In this way, the role played by universities in reaching the ob...
