For producing realistic images, reflection is an important visual effect. Reflections of the environment are important not only for highly reflective objects, such as mirrors, but also for more common objects such as brushed metals and glossy plastics. Generating these reflections accurately at real-time rates for interactive applications, however, is a difficult problem. Previous works in this...

The Best-Offset (BO) prefetcher submitted to the DPC2 contest prefetches one line into the level-two (L2) cache on every cache miss or hit on a prefetched line. The prefetch line address is generated by adding an offset to the demand access address. The BO prefetcher tries to find automatically an offset value that yields timely prefetches with the highest possible coverage and accuracy. It eva...

Computer modeling of 10 patients' computed tomographic scans was used to study the variables affecting hip arthroplasty range of motion before bony impingement (ROMBI) including acetabular offset and height, femoral offset, height and anteversion, and osteophyte removal. The ROMBI was compared with the ROM before component impingement and the native hip ROM. The ROMBI decreased with decreased t...

Control of band discontinuities in semiconductor heterostructures may introduce a new important degree of freedom in the design of heterojunction devices and allow independent optimization of carrier injection, carrier confinement and ionization thresholds in high speed and optoelectronic devices. We will review recently proposed methods to microscopically control heterojunction parameters by m...
