The realization of sustainable development depends on the efficient use of energy resources. Energy consumption productivity and efficiency are among important indices that play a critical role in explaining the behavior of energy consumption structure of different economic sectors, which in turn, plays a key role in policy making. From among economic sectors, the agriculture sector, as an impo...
this paper surveys economic growth and energy consumption relationship by new econometric methods in different sectors of iran. this study uses panel error correction model and panel co integration and causality tests to investigate short run and long run relationship between energy and value added growth in different sectors of iran’s economy with regards to energy price in the time period of ...
cities are a focal point of energy consumption. accessibility to public services has a significant impact on the balance of public and private energy uses, which are two sectors that are directly affected by urban planning (the third is industrial). this paper establishes the relative magnitudes of service accessibility enhancement on urban energy efficiency in comparison to other factors, and ...
with the increasing world population and limitations on arable land, increasing the yield per unit is one of alternatives human food supply. greenhouse cultivation as one ways of increase the performance can arrive this purpose. but the energy restriction of another human challenges, so that increase the performance without considering energy consumption almost appears to be meaningless. due to...
The changes of spatial pattern in energy consumption have an impact on global climate change. Based on the spatial autocorrelation analysis and the auto-regression model of spatial statistics, this study has explored the spatial disparities and driving forces in energy consumption changes in China. The results show that the global spatial autocorrelation of energy consumption change in China is...
energy as an important production factor has significant effects on economic growth. identifying the relationship between energy and economic growth can help to improve governmental energy policies. applying ardl and ecm methods, this paper examines the longrun and shortrun causality relationships between (1) energy consumption and economic growth and (2) energy consumption and employment in va...
We present a tool that, using a team's existing test cases, performs repeated measurements of energy consumption based on instructions executed, objects generated, and blocking latency, generating a distribution of energy use estimates for each test run, recording these distributions in a time series of distributions over time. Then, when these distributions change substantially, we inform the ...
Focal changes in the cerebral metabolic rate of glucose utilization (CMRglc) are small (10-40%) during sensory activation in awake humans, as well as in awake rodents and primates (20-50%). They are significantly larger (50-250%) in sensory activation studies of anesthetized rats and cats. Our data, in agreement with literature values, show that in the resting anesthetized state values of CMRgl...
Introduction & Objective: Common methods for dewatering of wastewater sludge need chemi-cals and high energy consumption and have low efficiency and environmental acceptability because of colloidal and jelly property of bacteria cells of sludge. Furthermore, their operat-ing is completely complicated. In this study electro-flotation way, as a novel method, was performed to cover these limitatio...
