Cylindrical holes were once the industry standard for air film cooling on turbine engine components. The cooling holes were traditionally formed using an electro-discharge machine (EDM) with a round ...

Even as technology advances—leaving many of the old ways of building obsolete—certain traditional crafts and building techniques continue to captivate our imaginations with their simple ingenuity and ...

High-speed digital simulations usually begin with a time-domain specification of the driving signal. The specification calls out every moment at which the driving signal, or “excitation,” should ...

Researchers at Caltech make progress in medical imaging by adapting astronomical optics. A reflector shapes light waves to counterbalance distortion. Researchers in Caltech’s Andrew and Peggy Cherng ...
