This paper presents a passivity-based control (PBC) design methodology for three-phase voltage source inverters (VSI) for uninterruptable power supply (UPS) systems where reduced harmonic distortions for the nonlinear load, reduced output voltage overshoot, and a hubbell 5362w restricted settling time are required.The output filter design and modif
Correlation between air pollutants concentration and meteorological factors on seasonal air quality variation
Introduction: Hitherto studies have concentrated on the pollution concentration in an ambient environment not putting into cognizance meteorological factors that can determine the fate/trail of the pollutant in the atmosphere.Materials and methods: Accordingly, the study monitored ambient topical air triplicate day-time concentration of NO2, PM10,
Autobullectomy: A rare case of spontaneous resolution of infected giant bullae
Introduction: Bullous lung disease is a common presentation in patients with chronic obstructive pulmonary disease (COPD).The giant pulmonary bulla occupies one third of involved hemithorax and characterized by the existence of centrilobular emphysema in non bullous lung.Sometimes air reabsorbs spontaneously leading to shrinkage and regression of b
First-in-human demonstration of floating EMG sensors and stimulators wirelessly powered and operated by volume conduction
Abstract Background Recently we reported the design and evaluation of floating semi-implantable devices that receive power from and bidirectionally communicate with an external system using coupling by volume conduction.The approach, of which the semi-implantable devices are proof-of-concept prototypes, may overcome some limitations presented by ex
POWER TRANSMISSION LINE RECONSTRUCTION FROM SEQUENTIAL OBLIQUE UAV IMAGES
With the accelerated development of the global economy, the scale of UHV (Ultra High Voltage) large-capacity transmission lines has increased dramatically.Nevertheless, existing transmission line inspection methods rely on human inspectors detecting abnormal facilities from ground level or helicopters.Those methods not only require extremely high l
