ABSTRACT Characterizing the sub-mm Galactic emission has become increasingly critical especially in identifying and removing its polarized contribution from one emitted by cosmic microwave background (CMB). In this work, we present a parametric foreground removal performed on to sub-patches identified celestial sphere means of spectral clustering. Our approach takes into account efficiently bot...

Space is the driving force of world’s sustainable development, and ensuring sustainability human activity in space also necessary. Robotic arm active debris capture removal (RA-ADCR) a noteworthy technology for containing dramatic increase maintaining orbital safety. This review divides RA-ADCR progress history into three periods presents status related research. Two major development trends ar...

background: electrochemical methods, as one of the advanced oxidation processes (aops), have recently been applied to remove different contaminants from water and wastewater. this study compares the performance of anodic oxidation (ao) and electro-fenton (ef) methods on waste sludge treatment. methods: this experimental study was performed on real sludge and the effect of operating parameters s...
