The ever-increasing demand for high data storage capacity has spurred research on development of innovative technologies and new storage materials. Conventional GByte optical discs (DVDs and Bluray) can be transformed into ultrahigh capacity storage media by encoding multi-level and multiplexed information within the three dimensional volume of a recording medium. However, in most cases the rec...

The magnetic relaxation of ferromagnetic powders has been studied for many years, largely due to its importance to recording technologies. However, only recently have experiments been performed that resolve the magnetic state of individual sub-micron particles. Motivated by these experimental developments, we use droplet theory and Monte Carlo simulations to study the time and field dependence ...

For System-on-Chip (SoC) using deep sub-micron technologies, semiglobal and global interconnects are susceptible to crosstalk defects that may lead to mal-function and timing failures. Removal of crosstalk defects is becoming important to ensure error-free operation of an SoC. To efficiently evaluate crosstalk-defect coverage, it is necessary to understand the factors affecting this noise. In t...

Optical Coherence Tomography (OCT) is a novel biomedical imaging technique which uses lowcoherence optical interferometry to obtain micron-scale resolution tomographic images of subsurface tissue structure noninvasively. We have developed OCT scanners compatible with minimally invasive delivery technologies (i.e., biomicroscopy, endoscopy) capable of imaging up to video rate. Clinical studies o...

We present new room-temperature 1100 - 1800 cm^{-1} spectra of melilite silicates and 600 2000 three randomly orientated fine-grained carbonates to determine the possible carrier(s) a 6.9~micron absorption feature observed in variety dense astronomical environments including young stellar objects molecular clouds. focus on low-mass post-AGB star Sakurai's Object which has been forming substanti...

fuel wood provides the main source of energy for cooking and space heating for over 80 percent of households living in kenya. the heavy reliance on the biomass energy has exerted an imbalance in demand and supply consequently resulting in adverse environmental effects in kenya. as part of innovation efforts, several energy-conserving technologies have been developed. a unique cook stove named m...
