Normal 0 false false false EN-US X-NONE AR-SA MicrosoftInternetExplorer4 Measurement of solar radiance demands expensive devices to be used. Alternatively, estimator models are used instead. In this paper, a new method based on the empirical equations is introduced to estimate the monthly average daily global solar radiation on a horizontal surface. The proposed method uses Intelligent Water ...

Abstract Optical tweezers are powerful tools based on focused laser beams. They able to trap, manipulate, and investigate a wide range of microscopic nanoscopic particles in different media, such as liquids, air, vacuum. Key applications this contactless technique have been developed many fields. Despite progress, optical trapping planetary exploration still be developed. Here we describe how c...

Daily solar radiation forecasting has recently become critical in developing energy and its integration into grid systems. Despite the huge number of proposed techniques, an accurate estimation remains a significant challenge because non-stationary variation components due to continuously changing climatic conditions. Usually, several input data predictors are used for process, which can cause ...

The vast range of the electromagnetic spectrum and the wide range of potential signaling methods make comprehensive searches for extraterrestrial signals difficult. Perhaps because of this, in nearly five decades of SETI searches no indications of extraterrestrial civilization have been seen. Expanding technologies and new instruments can help close the gaps in the SETI search space. New techni...

We estimate the frequency of intermittent hypermutation events and disruptions of planetary/satellite photochemistry due to ultraviolet radiation from core collapse supernova explosions. Calculations are presented for planetary systems in the local Milky Way, including the important moderating effects of vertical Galactic structure and UV absorption by interstellar dust. The events are particul...
