It is extremely critical for an emergency response to quickly and accurately use source term estimation (STE) in the event of hazardous gas leakage. To determine appropriate algorithm, four swarm intelligence optimization (SIO) algorithms including Gray Wolf optimizer (GWO), particle (PSO), genetic algorithm (GA) ant colony (ACO) are selected be applied STE. After calculation, all can obtain le...

<span lang="EN-US">This paper presents a new control strategy based on the combination between resonant controller and disturbance-observer (RSCDO) for stand-alone four-leg Voltage Source Inverter (VSI). The aim of is to regulate inverter output voltage, reducing as much possible voltage Total Harmonic Distortion (THDv) in every load condition. allows adjust fundamental harmonic, whereas ...

This paper proposes and demonstrates, in full scale, a novel type of energy geostructure (“the Climate Road”) that combines ground-source heat pump (GSHP) with sustainable urban drainage system (SUDS) by utilizing the gravel roadbed simultaneously as an source rainwater retarding basin. The Road measures 50 m × 8 1 (length, width, depth, respectively) has 800 geothermal piping embedded roadbed,...
