This research (1) integrated a fluorescent dye injection and monitoring system for measuring the mixing of a fluorescent dye tracer (fluorescein) in permeable (sandy) sediments with a cabled ocean observatory, Kilo Nalu, Oahu, Hawaii, and (2) used this system to conduct remotely controlled in situ measurements of wave-enhanced porewater mixing in a physically well-characterized wave-dominated s...

This chapter describes the challenges of effectively utilizing distributed resources in a new Professional Campus Environment. In this environment, the synthesis and manipulation of multimedia data from physically distinct locations is a critical activity which requires development of advanced network technology. Such a network will make use of fiber-optic interconnects, highthroughput, low-lat...

In this thesis we explore a novel technique to fabricate sub-micron diameter tapered fibers for sensor applications. Physically the light propagating in a tapered fiber has an evanescent field that extends into the medium surrounding the fiber containing an analyte. A sub-micron diameter taper can expels most the electromagnetic energy into the medium thus increasing the sensitivity of the meas...

Diffusion-weighted MRI has enabled the imaging of white matter architecture in vivo. Fiber orientations have classically been assumed to lie along the major eigenvector of the diffusion tensor, but this approach has well-characterized shortcomings in voxels containing multiple fiber populations. Recently proposed methods for recovery of fiber orientation via spherical deconvolution utilize a sp...

Background and Objectives: Constructs of behavioral models such as trans-theoretical model can be associated with healthy eating behaviors like increasing fiber intake. They can also be effective in improving these behaviors in patients with diabetes. This study aimed to assess the association of self-efficacy and decisional balance with stages of change for fiber intake and glycemic control in...

Lamb wave propagation in fiber-reinforced composite plates is featured by a pronounced directivity of wave energy transfer along the fibers from a point surface source. In the case of non-point (sized) source, the main lobe of radiation diagram may turn with frequency up to the orthogonal to the fibers direction. This effect has been theoretically studied and physically explained in the context...
