Wind power production has been under the main focus for the past decade in power production and tremendous amount of research work is going on renewable energy, specifically on wind power extraction. Wind power provides an ecofriendly power generation and helps to meet the national energy demand when there is a diminishing trend in terms of non-renewable resources. This paper reviews the modeli...

The purpose of the research was to study the effect of microwave power inpretreatment of fresh waterhyacinth on biogas production. The variations of microwave power levels are 240; 400; 560 and 800 W. The variations of microwave heating time are 5; 7 and 9 min. The unpretreated fresh water hyacinth are used as control. The result of research showed that the microwave pretreatment of fresh water...

due to the increasing cost and environmental impacts of fossil fuel consumption, using the renewable energies in data center has become an important and essential priority. although using renewable energies has less environmental harmful effects, but the high investment needed for their installations as well as their fluctuating power production characteristic, restricts their usage such that m...

this paper aims to signalize the substantial fact that the major focus and the joint aspect to fulfill the purposes of human development, sustainable development, social justice, competitive power and resilience of national economy is to promote the power of national production. to fulfill this purpose, we used institutional theoretical system for presenting the analysis and signalized the meth...

In a wind farm, the upstream wind turbine may cause power loss to the downstream wind turbines due to the wake effect. Meanwhile, the energy production is determined by the power generation and the lifetime of the wind turbine. In this paper, an optimal active power control method is proposed to maximize the energy production of wind farms by considering the wake effect and the lifetime of wind...

in the last years of the twentieth century and the early years of the twenty first century, globalization with all its aspects and effects, has laid a ground which has originated and/or deepened structural weaknesses of states, their inability to answer the citizens’ demands and functional crisis of states. formation of international institutions, international non-governmental organizations (n...
