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 paper, an attempt has been made to introduce a new control strategy including plug-in hybrid electric vehicle (phev) and diesel engine generator to control the voltage and frequency of autonomous microgrids. the proposed control strategy has multiple advantages over the recent control methods in microgrids. the proposed method applies the primary and secondary frequency control strategy...

At present, a major concern regarding data centers is their extremely high energy consumption and carbon dioxide emissions. However, because of the over-provisioning of resources, the utilization of existing data centers is, in fact, remarkably low, leading to considerable energy waste. Therefore, over the past few years, many research efforts have been devoted to increasing efficiency for the ...

A WSN (wireless sensor network) consists of thousands of sensor nodes which have limited energy, memory, and computation capability. In some of extreme environment, it becomes difficult to replace the sensor nodes once they used up the resources. Therefore, many researchers in this field focus on how to design an efficient routing protocol to prolong the life span of the network. The hierarchic...

Mobile devices, such as smartphones, have become an important part of modern lives. However, as these devices have tremendously become popular they are attracting a range of attacks. Malware is one of the serious threats posed to smartphones by the attackers. Due to the limited resources of mobile devices malware detection on these devices remains a challenge. Malware detection techniques based...

due to shortage of precipitation and the spatial and periodical disparity of rainfalls, iran iscounted among the arid and semi-arid countries of the world, and therefore the water utilities have put thecontrol of consumption and efficient use of water high on their priorities. water consumption management isconsidered as a field of energy management, and the impacts of effective measure related...

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...

The current economic paradigm, which is based on increasing human population, economic development, and standard of living, is no longer compatible with the biophysical limits of the finite Earth. Failure to recover from the economic crash of 2008 is not due just to inadequate fiscal and monetary policies. The continuing global crisis is also due to scarcity of critical resources. Our macroecol...

Mobile Ad Hoc Networks (MANET) can be considered as a class of unstructured networks created by a number of autonomous wireless and sensor nodes. The inherent characteristics of such networks have made specific applications, such as multimedia transfer and challenging. Basically, the functionality of a node and very few resources directly affect the delivery of packets which depends on the ...

An important task of operating systems is to schedule shared resources fairly between several parties. Precise accounting of consumed resources is the key to that goal. However, most operating systems only use very basic accounting strategies. This thesis discusses methods for resource accounting and introduces a powerful, yet easy to use accounting model based on resource containers. The goal ...
