This paper studies how to exploit the predicted information to maximize energy efficiency (EE) of a system supporting hybrid services. To obtain an EE upper bound of predictive resource allocation, we jointly optimize resource allocation for video on-demand (VoD) and real-time (RT) services to maximize EE by exploiting perfect future large-scale channel gains. We find that the EE-optimal predic...
The rapidly growing world energy use has already raised concerns over energy resources and greenhouse gas (GHG) emissions. Since the global contribution from residential buildings towards energy consumption, has steadily increased between 20% and 40% and as large openings have considerable energy and heat loss in dwellings, this paper establishes a coefficient of heat loss and air infiltration ...
Increasing energy cost and reduction of fossil fuel resources have been resulted in increasing demand of renewable energy, such as micro biomass particles in small scale Stirling engines to generate combined heat and power. In such Stirling engines, biomass particles are burnt in external combustion chamber and then, the generated heat is transferred to the working fluid of the engine cycle. Th...
Energy is one of the most important requirements in development of societies. In the last decade, widespread attention has been paid to renewable energies. Despite the obvious advantages of renewable energy resources, their dependence on climate change is one of the most fundamental problems facing to the development of them. Optimal design of hybrid renewable energy systems is a major issue in...
Offsetting cities’ dependence on fossil fuels is one of the key factors for meeting the environmental targets set out by the European Commission (EC) by 2020 [3]. The penetration of small-scale renewable resources in domestic households (photovoltaic panels and micro wind mills) empowers dwellings to collectively reduce their carbon footprint. Incentivizing the injection and trade of locally-pr...
in the present study an attempt has been made to use a non-parametric method data envelopment analysis (dea) for assessing source-wise and operation-wise the technical efficiency (te) and return-to-scale (rts) for paddy production in four zones of the state of punjab, india. the results were then compared to corresponding ones already obtained from a parametric method (cobb-douglas production f...
