Calculation of Hall coefficient in semiclassical approach requires the first and the second derivatives of the energy bands at the Fermi level. We use the Maximally Localized Wannier Function technique to determine the required band derivatives and calculate the ordinary Hall conductivity and ordinary Hall coefficient in Al,Cu, Pd, Li, Au, Ag and Pb cubic metals.
Energy outputs from ethanol produced using corn, switchgrass, and wood biomass were each less than the respective fossil energy inputs. The same was true for producing biodiesel using soybeans and sunflower, however, the energy cost for producing soybean biodiesel was only slightly negative compared with ethanol production. Findings in terms of energy outputs compared with the energy inputs wer...
In driving and when you brake, a lot of energy is dissipated to stop the car; especially in urban areas where the vehicle is driving in a stop-and-go pattern. This energy, which is dissipated by the brake pads, can be stored in the vehiclechr('39')s battery. In Hybrid and Electric Vehicles, a regenerative brake can be used alongside the mechanical brakes to regenerate some energy while braking....
The indispensable vital structure in any harbor is a breakwater in order to make available calm water region inshore. Pile breakwater can be employed as a small coastal protection structure where tranquility required is low. This study is concerned with CFD study on the performance of perforated hollow pile to dissipate wave energy and the novelty of this investigation is the role of perforatio...
With increasing population, demand for chicken meat has increased and resource constraints have led to increased production with an emphasis on improving the productivity of inputs and energy indices, so studying energy consumption in broiler production is important. One of the important issue in broiler industry is energy consumption. In this study, energy consumption flow and amount of energy...
With the increasing installed capacity of desalination, the greenhouse gas emission for generating the required energy to power the desalination plants is also becoming the focus of attention in the world community. Domestic reverse osmosis membranes have been very successful technology especially in the developing world to provide safe drinking water. The novel concept of photovoltaic powered ...
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...
