Process Parameter Influence on Tensile Property of Friction Stir Processed Al/Ni-Fe Composite
Annals of "Dunarea de Jos" University of Galati, Fascicle XII, Welding Equipment and Technology, 2020 Friction stir processing (FSP) is a solid-state processing technique that has proven to be an efficient surface modification process for producing aluminium matrix composites (AMCs). However, practical challenges still occur during the processing of AMCs

Speed of Light on Rotating Platforms
Foundations of Physics, 1998 It is often taken for granted that on board a rotating disk it is possible to operate a \QTR{it}{global}3+1 splitting of space-time, such that both lengths and time intervals are \QTR{it}{uniquely} defined in terms of measurements performed by real rods and real clocks at rest on the platform.
