Firsthand Lessons in Globalization
The best way to prepare U.S. engineering students to be globally competitive, says Belle Wei, dean of engineering at San Jose State University, is to show them what they're up against. That's why Wei pioneered the school's Global Technology Initiative, which sends selected students on an expenses-paid tour of Asian companies and universities. Wei also works closely with Silicon Valley com.

JPEG2000 Codec for Robust, Scalable Video
The JPEG2000 wavelet-based algorithm generates a compressed codestream that retains the ability to easily extract different representations of the image, including different frame dimensions, without transcoding or recompressing. Yes, the name sounds dated (note MPEG-4 is even older, dating to 1998) but with the ability to simultaneously deliver HD and lower resolution video from the same signal, the six-year old JPEG2000 codec has a very bright future for broadcast, surveillance and consumer video applications, says Analog Devices.

Taking Care Of Data
Time travel is perhaps the most alluring feature of continuous data protection, or CDP. In stark contrast to traditional nightly data backups to tape, CDP solutions record every change to specified file types, allowing government users to move systems backward in time--two hours or even two minutes--and recover information that was perfectly intact before a nasty virus hit or servers crashed.

Implementing Matrix Inversions in Fixed-point Hardware
We impliment fixed-point matrix inversion on a Virtex-4 FPGA using a synthesizable QR-decomposition MATLAB model and the AccelDSP Synthesis tool. The resulting function occupies 12% of a XC4VSX55 device and has a 1.7 MSPS data rate.
