John W.M. Bush, an associate professor in mathematics at MIT, has studied the underlying hydrodynamics of the seemingly miraculous feat of walking on water (as some insects do). By using mathematics, high-speed photography, and flow visualization techniques, he discovered something short of a miracle: The insects use one set of legs like oars, sculling their way across the water's surface. A full report is in the August 7 issue of Nature Magazine.
This slideshow includes several versions of multi-materials machines, two different composites processes including one at microscale, and two vastly different metals processes. Potential game-changers down the line include three microscale processes.
Hosted CAD or PDM systems is an emerging technology that offers many advantages over traditional on premise workstation CAD configurations and is making many companies rethink how to deliver future CAD software solutions.
