Study on the unbalanced current injection capability of grid-connected photovoltaic neutral-point-clamped inverter
Due to high penetration of distributed generation units in power system, fault ride through (FRT) capability is one of the new requirements of the medium-scale grid-tied photovoltaic power plants (PVPPs). This paper proposes ...
Effect of Exergames on Depression: A Systematic Review and Meta-Analysis
Depression is a major public health concern in current society. In recent years many studies began to investigate the potential benefits of exergames on depression. The current study aimed to provide a systematic review ...
Southeast Asia’s recurring smoke haze crisis : what can be done?
The smoke haze crisis in Southeast Asia has come back with a vengeance, threatening the lives and health of millions. No one seems to know how best to deal with it or how long it will last this time.
Iterative tuning strategy for setting phase splits with anticipation of traffic demand in urban traffic network
Facing large-scale urban traffic network, countless effort has been made toward intelligent and efficient urban traffic control system to better use existing traffic infrastructures. Recently, a novelty pre-timed traffic ...
Hierarchical Sandwich-Like Structure of Ultrafine N-Rich Porous Carbon Nanospheres Grown on Graphene Sheets as Superior Lithium-Ion Battery Anodes
A sandwich-like, graphene-based porous nitrogen-doped carbon (PNCs@Gr) has been prepared through facile pyrolysis of zeolitic imidazolate framework nanoparticles in situ grown on graphene oxide (GO) (ZIF-8@GO). Such ...
Surface Plasmon Polariton-coupled Waveguide Back Reflector in Thin-film Silicon Solar Cell
Surface plasmon polariton (SPP) waveguide-coupled back reflector geometry is proposed for efficient light trapping and broadband absorption enhancement in thin-film silicon solar cells. The proposed geometry takes advantage ...
Triggers of key calcium signals during erythrocyte invasion by Plasmodium falciparum
Invasion of erythrocytes by Plasmodium falciparum merozoites is a complex multi-step process mediated by specific interactions between host receptors and parasite ligands. Reticulocytebinding protein homologues (RHs) and ...
Laboratory measurements of vortex-induced sediment pickup rates
In the present study, vortices were generated in open channel flow with a cross-flow cylinder installed horizontally near the bed. Sediment pickup rates were then measured over the channel bed downstream the cylinder using ...
Construction of Efficient 3D Gas Evolution Electrocatalyst for Hydrogen Evolution: Porous FeP Nanowire Arrays on Graphene Sheets
A novel 3D hierarchical nanocomposite of vertically aligned porous FeP nanowires on reduced graphene oxide is prepared as a demonstration of constructing an efficient hydrogen evolution catalyst. Extension of this ...
Is ‘Trojan Horse’ : seeing wood for the trees?
Western media reports have played up the threat of Islamic State “sleeper cells” infiltrating Europe with the recent refugee exodus. Do these reports reflect genuine concerns or over wrought fear-mongering? What are the ...
