A composite photonic crystal that allows on-chip control over the emission direction of a semiconductor laser diode looks set to benefit mobile projection displays, lasers printers and chip-to-chip ...

When used in structural engineering, the term deflection refers to load-induced displacement, which typically affects beam designs. It can be an extremely complicated value to calculate when ...

The construction of concrete-filled steel tube tied-arch bridges typically employs the “beam first and arch later” methodology. In this approach, tie beams are initially constructed on temporary ...
