To overcome the detrimental effect of residual stress in welded joints, which affects the overall performance of the welded structure, this paper studies the magnitude and distribution of residual stress after welding and local post-weld heat treatment (PWHT).The coupled thermo-metallurgical-mechanical model for welding 6 mm thick Ti-6Al-4V (TC4) t
For wildland firefighters, the ability to efficiently evacuate the fireline is limited by terrain, vegetation, and fire conditions.The impacts of terrain and vegetation on evacuation time to a safety zone may not be apparent when considering potential control locations either at the time of a wildfire or during pre-suppression planning.To address t
RasGRP1 and SOS are Ras-specific nucleotide exchange factors that have distinct roles in lymphocyte development.RasGRP1 is important in some cancers and autoimmune diseases but, in contrast to SOS, its regulatory mechanisms are poorly understood.Activating signals lead to the membrane recruitment of RasGRP1 and Ras engagement, but it is unclear how
Operation optimization for large-scale offshore wind farms can cause the fatigue loads of single wind turbines to exceed their limits.This study aims to improve the economic profit of offshore wind farms by conducting multi-objective Standing Wooden Plaque optimization via decoupled group operations of turbines.To do this, a large-scale wind farm i
