Deploying new healthcare technologies for proactive health and elder care will become a major priority over the next decade, as medical care systems worldwide become strained by the aging populations. This thesis presents ...

Image segmentation, the process of decomposing an image into meaningful regions, is a fundamental problem in image processing and computer vision. Recently, image segmentation techniques based on active contour models with ...

Silicon nanoparticles are candidate charge trapping and storage elements for future high density, low-voltage nonvolatile memory devices. Most previous works have studied nanoparticles of larger than 5 nm size and exhibited ...

The progress of large-area 2D- and 3D-photonic crystals (PCs) at optical and near infra-red frequencies has been limited by fabrication challenges. Periodic nanostructures must be patterned in high-index and crystalline ...

A set of novel mechanisms for the manipulation of light in the nanoscale is provided. In the class of all-dielectric material systems, techniques for the suppression of radiative loss from incomplete-photonic-bandgap ...

The theory, design and experimental results of a wideband 140 GHz, 1 kW pulsed gyro-traveling wave amplifier are presented. The gyro- TWA operates in the HE(0,6) mode of a novel cylindrical confocal waveguide using a ...
