Energy harvesting

This paper evaluates an energy harvesting strategy for UAVs from sunlight and laser beams on cloudy days with a low-level cloud layer. The channel models and harvested powers for both cases are considered and analyzed using mathematical equations and simulation results.

This paper investigates the system performance of hybrid time-power switching based relaying (TPSR) energy harvesting enabled in the multisource half-duplex relaying network over the Rayleigh fading channel. The outage probability (OP) of the proposed system model with implementing maximal ratio combining (MRC) and selection combination (SC) technique at the receiver is presented and analyzed.

The aim of this thesis is investigate and design a small antenna which can be embedded onto a Polyethylene substrate (used for making roof tiles). The antenna can be used to harvest ambient energy by connecting it to a rectifier. Due to the dimensional constraints of a roof tile as well as the materials used, there are limitations imposed on the antenna size, and thus the radiation efficiency and bandwidth often become a limiting factor in the overall performance of the system.

The efficiency of light harvesting in higher plant photosynthesis is regulated in response to external environmental conditions. Under conditions of excess light, the normally highly efficient light-harvesting system of photo-system II is switched into a state in which unwanted, potentially harmful, energy is dissipated as heat.

Dams and particle separation is important in the process of harvesting rice (rice; wheat) and energy intensive. There have been many studies on various parts of the dam to improve your drum beats combine harvesters were introduced in recent years. Research division beating drums beating two types of tangential to the direction tangential feed was made in 2007 with the aim of: increasing particle separation distribution of the dam, the dam reduced energy costs, reduce the impact split ...
