Effects of surface active elements on weld pool formation using TIG arcs
Abstract A-TIG welding is the welding process where powdered activating flux (welding facilitating agent) with oxides such as TiO2 and Cr2O3 as the main constituents is dissolved by volatile solvent, such as methyl ethyl ketone and acetone and is applied using a brush, in advance, on the base metal surface which is then subjected to TIG welding.1 A ...

Channel Estimation for Reconfigurable Intelligent Surface With a Few Active Elements [PDF]
In this paper, a channel estimation technique for reconfigurable intelligent surface (RIS)-aided multi-user multiple-input single-output communication systems is proposed. By deploying a small number of active elements at the RIS, the RIS can receive and
