Clement Klienstreuer, a professor of mechanical and aerospace engineering at North Carolina State University, is using computer simulation and fluid dynamics for designing experimental blood vessels, arteries, and bypass grafts. With funding from the National Institutes of Health and the National Science Foundation, he is heading up a team of vascular surgeons and engineers aiming to design a better arteriovenous access graft. The grafts serve as portals through which blood passes for kidney dialysis and other procedures. Conventional designs are Teflon-based and prone to frequent failure. One of the keys to the new graft is a graft hood, which complicates its design, but improves blood flow. For a copy of the paper describing the new graft geometry, contact Linda E. Rudd, North Carolina State University Engineering Publications at email@example.com or call (919) 515-3848.
New versions of BASF's Ecovio line are both compostable and designed for either injection molding or thermoforming. These combinations are becoming more common for the single-use bioplastics used in food service and food packaging applications, but are still not widely available.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This radio show will show what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
