Design Of A Chemical Agent Detector Based On Polymer Coated Surface Acoustic Wave (Saw) Resonator Technology, Lane Leslie Manoosingh Jun 2004

Design Of A Chemical Agent Detector Based On Polymer Coated Surface Acoustic Wave (Saw) Resonator Technology, Lane Leslie Manoosingh

USF Tampa Graduate Theses and Dissertations

This dissertation presents the design of a unique prototype chemical agent detector which utilizes an array of polymer coated SAW resonators as the sensor elements. The design's particular embodiment is that of a testing platform for evaluating the utility of constructing a portable chemical agent detector, utilizing commercially available SAW resonators. It involves the consolidation of the sub-systems comprising a large laboratory development system, into a portable enclosure.

A combination of design techniques, utilized to achieve an overall balance between the physical dimensions of the system and its detection performance, comprises the unique nature of the overall design of this …


Near-Death Experiences, Religion, And Life After Death, Holly Wallace Apr 2004

Near-Death Experiences, Religion, And Life After Death, Holly Wallace

USF Tampa Graduate Theses and Dissertations

This thesis investigates current scientific literature on near-death experiences (NDE), focusing on two common types of models used to explain the NDE: biological models and spiritual models. Four biological models and two spiritual models are presented and evaluated. During the evaluation, particular emphasis is placed on how these models accommodate veridical evidence. I found that, of the biological models, only one could account for veridical evidence, whereas both of the spiritual models provided explanations of these strange occurrences. From this conclusion, the implications of NDE research on human survival are explored.
