Increasing energy demand and environmental problems caused by the consumption of fossil fuels have made the use of passive solar energy methods more necessary, especially in commercial centers. On the other hand, the growth of science and technology in the world and the use of intelligent systems in construction, has led to the completion of common methods. The purpose of this study is to inves...
To prevent further increases in energy consumption, the government of Iran commenced energy subsidy reform in 2010. This paper investigates the fuel conservation effects of the reform in Iran using a homothetic translog cost function that provides estimates of the own- and cross-price elasticities of fuel demands. The percentage reduction in fuel demands is estimated using the likely effect of ...
The Cloud Computing model leverages virtualization of computing resources allowing customers to provision resources on-demand on a pay-as-you-go basis. During recent years, the power consumption of datacenters in cloud environment attracted researchers. Optimization of energy consumption can be performed by different methods including virtual machine (VM) consolidation. This technique can reduc...
The limited resources of energy, the significant rise in energy consumption, and its devastating effects on the environment are among reasons to save and optimize energy consumption. To minimize the dependence on energy, innovative low-energy structures can be built. Since the maximum amount of energy (about 40 percent) is consumed in the building sector and most of it is spent in cooling, heat...
The ever raising request for energy and resource limitations in the world, particularly Iran, have ever increasing attention to intense research in optimization, and economization of energy consumption. Since, the application of traditional methods for production of sugar especially in Iran is associated with high consumption of energy and water, using of pulsed electric field (PEF) technology ...
Energy is one of the primary inputs in textile processing industries that have a significant impact on the cost of a cotton product. The energy cost-share is reported between 5-10% of the total production cost of woven cotton fabric in textile factories of developed countries. However, it is far higher in developing countries. This study aims to contribute to the understanding of energy use and...
many studies have been done on hybrid vehicles in the past few years. the full hybrid vehicles need a large number of batteries creating up to 300 (v) to meet the required voltage of electric motor. the size and weight of the batteries cause some problems. this research investigates the mild hybrid vehicle. this vehicle includes a small electric motor and a high power internal combustion engine...
Energy, as one of the most important production factors and also one of the most essential final products, has a special place in the economic growth and development of countries. Financial development is also known as one of the factors affecting economic growth, which can affect energy consumption in different ways. In this research, using composite data and the PVAR (vector autoregression) m...
Today, the agricultural sector is heavily dependent on energy to meet the growing demand of worldchr('39')s growing population food. This study aims to determine energy indices and equations based on its energy consumption and production. 380 farmers out of total number of 31190 irrigated wheat farmers of Isfahan were selected across the 24 borough of the province (based on Cochranchr('39')s r...
Due to increasing population and decreasing energy sources, this research studies the consumption of domestic energy. The purpose of this study is to predict the factors affecting household energy consumption. To do this, we use 3 algorithms, M5Rules, K-nearest neighbor and random forest, available in Weka software. In this study, the feature correlation algorithm is used to select the most imp...
