Electric utility regulators and policy makers implement incentive-based regulation to improve electric utilities efficiency or manage the cost of electricity. However, poorly implemented may produce undesired results such as low reliability poor quality service. Moreover, competition within electricity sector is likely be because high barriers entry, vertically integrated utilities, capital req...

abstract: enviromental concerns, improvements in renewable energy technologies, governmental incentives for the use of these resources, and increased t&d; costs, are the main factors driving the energy sector into a new era, where considerable portions of electrical demand will be met through widespread installation of distributed energy resources (ders). the virtual power plant (vpp) is a dece...

background: the i-space is a radiological imaging system in which computed tomography (ct)-scans can be evaluated as a three dimensional hologram. the aim of this study is to analyze the value of virtual reality (i-space) in diagnosing acute occult scaphoid fractures.   methods: a convenient cohort of 24 patients with a ct-scan from prior studies, without a scaphoid fracture on radiograph, yet ...

the purpose of this study was to evaluate the rate of using standards of designing electronic courses in educational contents of state-virtual universities in iran. the method of the study was a descriptive-survey one. the statistical population was the educational content of electronic courses in state-virtual universities such as university of science and technology, and shiraz university. da...

As the climate crisis worsens, power grids are gradually transforming into a more sustainable state through renewable energy sources (RESs), storage systems (ESSs), and smart loads. Virtual plants (VPP) an emerging concept that can flexibly integrate distributed resources (DERs), managing manage output of each DER unit, as well consumption loads, to balance electricity supply demand in real tim...

in this research, the calculation method of aerodynamic loads on an airplane in all flight situations is presented. in order to find an calculation equation for aerodynamic loads on an airplane in all flight conditions, the f-5 aircraft is selected as a prototype is divided into one hundred small parts longitudinally. therefore, the numerical solutions are taken place in different conditions of...

There is abundant literature regarding virtual reality as a technology of interest in the present age. However, there are few comprehensive studies on strategies that can improve the level of urban design research using this technique. To investigate the issue, this paper first reviews the concept of virtual reality. Next, the opinions of experts in the field of virtual reality technology are s...
