OPTIMIZATION OF ACTIVATED TUNGSTEN INERT GAS WELDING PROCESS PARAMETERS USING HEAT TRANSFER SEARCH ALGORITHM: WITH EXPERIMENTAL VALIDATION USING CASE STUDIES

Optimization of Activated Tungsten Inert Gas Welding Process Parameters Using Heat Transfer Search Algorithm: With Experimental Validation Using Case Studies

The Activated Tungsten Inert Gas welding (A-TIG) technique is characterized by its capability to impart enhanced penetration in single pass welding.Weld bead shape achieved by A-TIG welding has a major part in deciding the final quality of the weld.Various machining variables influence the weld bead shape and hence an optimum combination of machini

Detailed modeling of mountain wave PSCs

Polar stratospheric clouds (PSCs) play a key role in polar ozone depletion.In the Arctic, PSCs can occur on the mesoscale due to orographically induced gravity waves.Here we present a detailed study of a mountain wave PSC event on 25-27 January 2000 over Scandinavia.The mountain wave PSCs were intensively observed by in-situ and remote-sensing tech
