In this study, spatial and temporal profiles of an Nd-YAG laser beam pressure pulse are experimentally characterized and fully captured for use in numerical simulations of laser impact welding (LIW).Both axisymmetric, Arbitrary Lagrangian-Eulerian (ALE) and Eulerian dynamic explicit numerical simulations of the collision and deformation of the flye
A new aim for grassland management is to increase soil organic carbon (SOC) and to offset CO2 emissions by companies.This practice of carbon ranching may be informed by grazing-induced shifts in plant biomass and diversity which may foretell changes in SOC.Unfortunately, little is known about how grazing-induced shifts in plant properties correspon
Abstract One of the present great challenges is finding nonprecious materials characterized by efficient electrocatalytic behavior in order to substitute the expensive platinum-based materials for the purpose of hydrogen evolution reactions (HERs).In this study, ZIF-67 and ZIF-67 were used as precursors in order to fabricate metallic-doped N-enrich
Abstract A characterization technique, including a mathematical model involving extensive computational resources, is introduced to study the behavior of an electro-optical space switch based on semiconductor optical amplifier (SOA).The model encompasses the precise emulation of device Mat nonlinearities and its transient performance, allowing the
