Accurate prediction of the future electricity consumption is crucial for production electricity management. Since the storage of electrical energy is very difficult, reliable and accurate prediction of power consumption is important. Different approaches for this purpose were used. In this paper, Grey model (1,1) based on grey system theory has been used for forecasting results. Annual electric...

nowadays, transportation sector consumes about 27 percent of the whole energy in iran. therefore, after domestic and business sectors which consume about 40 percent of the whole energy, transportation is placed in the second rank. however, the financial value of transportation is of the highest importance. moreover, having 55percent of gasoline product consumption transportation has been also r...

globalization, increasing the global regulations of governmental and non-governmental organizations and customers’ request regarding to environmental compliance issues have led to organizations considering the green supply chain management to improve the environmental and economic performance. in order to maximize the efficiency of energy consumption and resources across the supply chain, green...

introduction: the relative costs of generating energy vary considerably depending on location. since hospital managers confront serious financial problems, they need to look for ways to use energy more efficiently. this study aimed to study the rate of energy use (water, gas and electricity) in a number of hospitals in isfahan from 1378 to 1382 and to compare the results with the available stan...

energy consumption in iran is a subject of debate. some may think that oil is cheap in iran and thus no need for this kind of research. this simple minding is erroneous first because iran subsidizes billion dollars each year for the imported diesel fuel specially for agricultural use and second because energy studies reveal the degree of professionally using the technology. we can easily find t...

One of the crucial questions to develop Autonomous Mobile Robotic systems is the energy consumption, its monitoring and management all along the mission. Mission complexity and fault tolerance capabilities require to exploit system redundancies, in terms of algorithms and hardware recruitment. This choice has an evident impact on energy consumption. This paper proposes an identification protoco...

abstract the aim of this study was to determine the input–output energy consumption in different levels of tomato production. the data used in the study were obtained from 140 tomato growers in different villages of marand township by using a face to face questionnaire. the results showed that the amount of energy consumed in tomato production was 65.2 gjha-1 which about 51% of this was generat...

Reducing energy consumption is critical to prolonging the battery life in portable devices. With rising energy costs and increases in energy consumption by devices in stationary systems energy expenses of large corporations can annually reach into millions of dollars. Subsequently, energy management has also become important for desktop machines in large scale organizations. While energy manage...

Managing power consumption while simultaneously delivering acceptable levels of performance is becoming a critical issue in several application domains such as wireless computing. We integrate compiler-assisted techniques with power-aware operating system services and present scheduling techniques to reduce energy consumption of applications that have deadlines. We show by simulation that our d...

Concerns about global Climate and sustainable energy are perhaps among the most inevitable and fanatical issues of the present time. To tackle concerns arising from high energy consumption and its adverse environmental impact, in recent years has caused manufacturers to establish energy management cell and policymakers to formulate policies. These Policies and required to be firmly held, in ord...
