Flexibility in the manufacturing of cold-formed steel (CFS) cross-sectional shapes provides a unique opportunity to improve load-carrying capacity these elements, leading more efficient and economic structural systems. This paper presents practical constrained optimization methodology for pin-ended anti-symmetric CFS beam-columns members with different lengths subjected various combinations axi...

The main purpose of this work is to shed light on the possibility producing huge amount energy based construction matter-antimatter plasma in a molecular crystal. It assumed that two beams isothermal hydrogen and antihydrogen are injected into palladium crystal leading state composed particles antiparticles. collapse releases which can be used as fuel for space shuttles. Thus, novel system pres...
