A common problem in molding high-precision plastics involves getting the molds sized so that parts come out in the correct size and shape. C-MOLD, a producer of CAE tools, thinks it has solved the problem, particularly for such unwieldy semi-crystalline materials as nylons or PETs, based on new simulation software it has developed. The "scientific procedure" for capturing the effect of crystallinity on material properties is based on research done by C-MOLD, the Cornell Injection Molding Program (CIMP), and experimental validation performed by the Polymers Department of the GM Research and Development Center. With the simulation, "we can now capture the cooling rate dependence of (shrinkage and warpage) properties by incorporating crystallization kinetics," says Manju Mahishi, project leader. No other simulation software uses fundamental material properties that yield this level of accuracy." E-mail firstname.lastname@example.org.
It won't be too much longer and hardware design, as we used to know it, will be remembered alongside the slide rule and the Karnaugh map. You will need to move beyond those familiar bits and bytes into the new world of software centric design.
People who want to take advantage of solar energy in their homes no longer need to install a bolt-on solar-panel system atop their houses -- they can integrate solar-energy-harvesting shingles directing into an existing or new roof instead.
Kaspersky Labs indicated at its February meeting that cyber attacks are far more sophisticated than previous thought. It turns out even air-gapping (disconnecting computers from the Internet to protect against cyber intrusion) isn’t a foolproof way to avoid getting hacked. And Kaspersky implied the NSA is the smartest attacker.
