This paper presents a thermoeconomic analysis of polygeneration system based on solar-assisted desiccant cooling. The overall plant layout supplies electricity, space heating and cooling, domestic hot water, freshwater for residential building. combines photovoltaic/thermal collectors, photovoltaic panels, biomass boiler coupled with reverse osmosis air conditioning. was modeled in TRNSYS simul...

Worldwide efforts are being made to increase the use of renewable energy in order to reduce the emission of greenhouse gases. Africa is blessed with abundant resources of fossil fuels as well as renewable energy resources. Yet the continent, especially sub-Saharan Africa, is afflicted with power crisis. For example, in Nigeria, erratic electricity supplies will persist unless the government div...

Shortage of electricity is one of the main problem in the development of rural areas in Pakistan. Photovoltaic techniques are generally attaining an escalating attention and they're to become very competitive alternative, additionally, environmental issues such as population and global warming impact are attracting experts towards green electricity sources such as solar systems. A standout amon...

On 6 May 1995, the Médecins sans Frontières (MSF) coordinator in Kinshasa, Democratic Republic of the Congo (DRC), received a request for assistance for what was believed to be a concurrent outbreak of bacillary dysentery and viral hemorrhagic fever (suspected Ebola hemorrhagic fever [EHF]) in the town of Kikwit, DRC. On 11 May, the MSF intervention team assessed Kikwit General Hospital. This i...

tant Abt Associates Inc, showed that 90% do not have a consistent water supply and 50% do not have electrical generators. “We never have a day without the electricity cutting off for 12 hours or longer, and half of these centers have no generator,” said Alwan. The same survey showed that 95% of those centers do not have gynecologic tables or electrocardiogram machines. “When we say there’s a sc...

A model predictive control (MPC) framework, exploiting both feedforward and feedback control loops, is employed to minimize large disturbances that occur in military water networks. Military installations’ need for resilient and efficient water supplies is often challenged by large disturbances like fires, terrorist activity, troop training rotations, and large scale leaks. This work applies th...

The spread of HIV in Ivory Coast is examined to evaluate Ivorian perspectives’ on which factors explicate the rising of HIV. This study reports the findings of an in-depth mixed method study with 39 teachers, 63 sixth grade students, eight school administrators, and 20 community elders. The study found that factors such as lack of condom distribution in school, high rates of sexual partner chan...

nowadays, electricity is one of the most significant infrastructures required for economic development of countries. hence, predicting electricity demand is very important especially in industry as a major electricity-consuming sector. the majority of studies under the subject of electricity demand have been performed by econometrics and it is not possible to investigate the effect of different...
