The energy gain reduction due to shadow inside a flat-plate solar collector
Renewable Energy, 2020Shadow on the absorber plate of a flat-plate solar collector or a solar cooker box can reduce absorbed energy. The main goal of this research is to investigate the effective factors on the shadow formation inside a solar collector.

MIMO gain and energy efficiency in LTE
2012 IEEE Wireless Communications and Networking Conference (WCNC), 2012Current 3GPP specifications for LTE include the use of MIMO as a key technology. MIMO can be seen from two different perspectives: if increased data rates are targeted, for a given value of SNR, one gets improved data transmission; however, from an energy efficiency viewpoint, lower values of SNR are needed for the same reference data rate, therefore ...

In Mexico, the owners of homes use roof coating materials for waterproofing purposes and usually select them just for aesthetic reasons. In this work, four concrete roofs with different waterproofing materials (terracotta, white, gray, and black) were ...

The Biomass Energy Transformation and Energy Gain of Wheat
Advanced Materials Research, 2013The biomass replaces the petroleum as energy is involved in energy transformations. There are two grade transformations from the wheat which are the fuel ethanol and the marsh gas ferment. The study on their transformation mechanisms and how to improve their energy efficiency will be benefit for both the academic and practical significance.

High Energy Gain Upconversion in Monolayer Tungsten Disulfide Photodetectors.
Nano letters (Print), 2019Photodetectors usually operate in the wavelength range with photon energy above the bandgap of channel semiconductors so that incident photons can excite electrons from valence band to conduction band to generate photocurrent. Here, however, we show that
