Visualizations move researchers toward new era in aerospace design
At the Air Force Research Laboratory's
Computational Sciences Center in Ohio, research
aerospace engineer Dr. Jose Camberos and his colleagues are diligently working to coax accurate calculations of electromagnetic equations from a computer program, Cobra, originally based on the Cobalt 60 code for solving fluid dynamics equations. The effort represents a significant step towards to the Computational Science Center's ultimate goal: computer-simulated aerospace experimentation that is both reliable and comprehensive.

The magic of corporate strength from within
Companies garner their strengths from a variety of sources. Some get their power from the market position of their products. Others enjoy the strength that comes from being a large, well-funded organization. Intangibles like innovation, creativity, and customer service can be the driving force behind success. However, Rick Carmichael, vice president of corporate marketing, Nextest
Systems, believes there is another source of power that can be
at the core of a great company's success. It's
called energy and drive. Read the full article
Making a living shooting onesies and twosies
In the dialect of the manufacturing belt along Lake Michigan,
"shooting a onesie" is machinist slang for a
single fabrication of a part from specs.
Traditionally, manufacturers, designers, and
inventors had to wait in line at their local machine
shop for these small custom orders. Now, with the
advent of home CNC machining and request-for-bid
websites, prototype work is going to machinists
working for themselves. Read the full article

Inexpensive adaptive optics achieved by Sandia's optical clamp
Sometimes a poor man's tool is all it takes. Adaptive optics, known for its computer control of subdivided, individually angled mirrors, is an efficient but expensive way to correct distortions in laser beams. The mirrors automatically adjust until an undistorted beam is obtained in a way formerly thought unachievable by a single large mirror. Now researchers at Sandia National Laboratories have developed a device (resembling an inexpensive vise similar to those bolted to many home workshop benches) that corrects optical distortions simply through pressure changes to a single reflecting surface.

Wheels: Computers expose the physics of NASCAR
It's an odd combination of Navier-Stokes equations and NASCAR driving. Computer scientists at the University of Washington have developed software that is incorporated in new technology that allows ESPN audiences to instantaneously see how air flows around speeding cars. Read the full article

GearedUp Share your opinions and ideas on designs and pressing industry topics This week: Tinkering with products
Last week, teenager George Hotz announced to the world that he'd unlocked the infamous iPhone from AT&T's exclusive contract with Apple. The move frees iPhone users to use SIM cards from other networks. Hotz and his collaborative team of international hackers took over 500 hours and a mountain of Red Bull to complete the step-by-step process instructions over the course of the last two months. Since engineers are constantly tinkering with their own stuff, what kind of other modifications have you made to some of your favorite after-market products? Read the full article
