Before the modern era, cities were built on a scale that did not change the environmental balance significantly. With the expansion of population and the expansion of cities and the conversion of settlements into big cities and metropolises, new conditions have emerged which show that cities today make their own climates. The new climates created in these areas are completely different from the...
Energy as one of the most important factors of production, as well as one of the most important marginal products, has effential role in trade and economic development.The importance of energy has increased after the two oil crises in 1970’s. The relationship between energy and trade is an important topic to study for several reasons. If energy consumption is found to Granger cause export...
Abstract This study was conducted to reduce energy consumption and consumed electricity costs at drinking water pumping stations in villages located at the central part of Khorramabad city in 2017. In this study, 10 wells and pumping stations from a total of 48 wells and pumping stations in Khorramabad were selected randomly. The energy consumption, energy intensity, the effect of the capacito...
the hot charging of continuously cast slabs steel is usually considered an effective method to reduce theenergy consumption in the hot rolling mills. in this work the application and optimizing of hot charging ofcontinuously cast slab in mobareke steel company has been investigated. mathematical relationship betweenthe cooling time of the stack of slabs and its mass average temperature is descr...
This study examines the relationship between energy consumption and economic growth in the Iranian economy. To that end, a wavelet transformation technique is used, which allows us to combine the time domain and frequency domain characteristics of two time series together. Using this approach and data for the period 1991:2 – 2017:1, this study tries to overcome the shortcomings of standard eco...
introduction in the wastewater treatment industry, the general attentionis mostly paidto the effluent quality standards. regardless of energy consumption, the treatment plants have been designed based on experience rather than the latest scientific findings.the treatment plants are considered as a part of energy equipment which largely consumed electrical energy.thus, electricity is the great p...
existed electricity grids deliver produced power to the consumer passing through transmission and distribution grids. according to high losses of these grids in transmission level and inexistence of bilateral interaction for simultaneous information exchange, a concept of smart grids were made by capabilities such as consciously participation of consumers in the smart electricity grids, an amou...
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...
