This study aims to optimize the energy supply system of a greenhouse considering twelve different climate conditions in Iran. For this purpose, an integrated two-objective linear energy optimization model has been developed to control the inside temperature and provide the required heating, cooling, and electricity by receiving electricity, gas, and water. The mentioned goals are to minimize op...
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...
during the 1960s, the relatively new approaches like environmental warfare and intentional environmental deterioration came in to the global security and strategic literature. till now, through different conventional and unconventional wars, the governments have imposed intentional and unintentional adverse effects on the environment some of which are lasting for decades. the application of wea...
The study assessed the quantity and value of food crop outputs of the gender categories in the Anambra state. At this research estimated the quantity and energy content of food stuffs consumed as well as required by each gender headed households, estimated the extent and magnitude of food security and insecurity in the area among the gender categories and examined the determinants of food secur...
the hydrogen abstraction reaction of oh radical with ch3ch2ocf2chf2 (hfe-374pc2) is investigated theoretically by semi-classical transition state theory. the stationary points on the potential energy surface of the reaction are located by using kmlyp density functional method along with 6-311++g(d,p) basis set. vibrational anharmonicity coefficients, xij, required for semi-classical transition ...
in forging design the significant parameters are maximum load or energy which are required for the selection of forging press or hammer. these two parameters are varied by the other paramelers such as the geometry of die cavity, flash dimensions, shape of the work piece, friction, mechanical properties of the metal to be forged, temperature, strain rate, and number of the forging operation. the...
Solar energy is a renewable energy source for power generation. The most important issue that today is the main barrier to using solar energy is its economic justifiably as compared to other electrication methods. The purpose of this paper is to feasible the construction of a 1 MW photovoltaic power plant connected to the network in order to provide part of the electrical charge required by the...
the monte carlo method can be used to describe any technique that approximates solutions to quantitative problems through statistical sampling. this method is considered to be the most accurate method for dose calculation in radiotherapy. for complete modeling of a linear accelerator, it is required that the manufactured information covers all data, but some data such as primary electron energy...
