This research will examine th...

A solar still is a viable option when the demand of potable water does not exceed more than 3 litres. Enhancement in distillate output from the solar still is a main goal of many researchers all over the world. In this research, the effect of copper and aluminium plates on distillate output is investigated experimentally as well as theoretically at different water depths under the same climate ...

The global auroral dissipation power as observed by the imager on the Polar spacecraft is used as a proxy for the power dissipation of the Earth’s magnetosphere to examine whether or not the magnetosphere is an avalanching system. It is found that the probability density distributions for the area and power of auroral activity sites have a power law component within a finite scale range, sugges...

In this study, an artificial neural network based model for prediction of solar energy potential in Kerman province in Iran has been developed. Meteorological data of 12 cities for period of 17 years (1997–2013) and solar radiation for five cities around and inside Kerman province from the Iranian Meteorological Office data center were used for the training and testing the network. Meteorologic...

The increased availability of solar energy potential, especially in southern latitudes as the Mediterranean Sea and Aegean regions, constitutes a strong motivation for design development floating offshore platforms suitable deployment operation sea environment. In this work, boundary element method is applied to hydrodynamic analysis pontoon-type structures carrying photovoltaic panels on deck....

Separating global horizontal irradiance measurements into direct and diffuse components has been vigorously discussed over the past half-century of solar radiation research leading to the creation of many models which attempt to compute these components with varying degrees of success. However, over the course of this discussion, nearly all studies have focused on hourly values, with no studies...

solar radiation data play an important role in solar energy relevant researches. these data are not available for some locations due to the absence of the meteorological stations. therefore, solar radiation data have to be predicted by using solar radiation estimation models. this study presents an integrated artificial neural network (ann) approach for estimating solar radiation potential over...

Over the past decade, Si bulk multicrystal has emerged as the substrate material for commercial solar cells. To accelerate the adoption of solar cells to the world, ongoing research targets further reductions in energy costs by improving material performance, while reducing manufacturing costs and raw material costs. We approached this issue from deep understanding of crystal physics of Si mult...

The magnetic structure and geomagnetic response of 73 magnetic clouds (MC) observed by the WIND and ACE satellites in solar cycle 23 are examined. The results have been compared with the surveys from the previous solar cycles. The preselected candidate MC events were investigated using the minimum variance analysis to determine if they have a flux-rope structure and to obtain the estimation for...
