This thesis investigates vibration-based damage identification problems in smart structures. Vibration-based damage metrics suffer from small sensitivity of modal properties to damage, thus making it difficult to detect, locate, and determine the...
Geology -- Guatemala -- Lake Atitlan area; Volcanism -- Guatemala -- Lake Atitlan area; Calderas -- Guatemala -- Lake Atitlan area.
Geological mapping, petrological and geophysical studies in the lake Atitlan area, Guatemala, have revealed four distinct periods of stratovolcano growth, each followed by major silicic eruptions and caldera collapse. The first period (12 - 11 my...

Many modern information management tasks consist of an observer that must maintain current knowledge of a collection of changing information. The goal of this observer is to maintain acceptably accurate state estimates given limited observation...
Coronary artery bypass graft (CABG) surgery is a leading treatment option for extending and/or improving the quality of life for patients suffering from heart disease. While we have witnessed improvements in mortality and morbidity secondary to...
The effects of vacancies on the mechanical properties of FeAl single crystals and polycrystals have been investigated. Scanning calorimetric results indicate that vacancies in quenched Fe-40Al undergo rearrangement at ~550K, and then annihilate at...

Neuropathic pain is a debilitating condition that affects millions of individuals worldwide. Unfortunately, opioids are only partially effective in treating neuropathic pain while entraining tolerance and a myriad of side effects from the high...
Photodynamic therapy (PDT) is used to cause specific tissue destruction, using photochemical reactions that result from light excitation of photosensitizer, which has localized in the target tissue. The process of photosensitizer photobleaching was...

The Internet has become a virtual place where people not only operate in isolation but also interact with other Internet users. Collaborative systems are becoming more popular. Applications now being introduced could provide better remote education...
The focus of this thesis is the study of nuclearity and exactness for groupoid crossed product C*-algebras. In particular, we present generalizations of two well-known facts from group dynamical systems and crossed products to the groupoid setting....
In order to most effectively investigate protein structure and improve protein function, it is necessary to carefully plan appropriate experiments. The combinatorial number of possible experiment plans demands effective criteria and efficient...
This research attempts to combine known methodology with new chemistry towards the preparation of extended polycyclic aromatic hydrocarbons (PAH). The generation and Diels-Alder trapping of 1,7- and 2,6-naphthalene bisarynes was attempted for the...
In this thesis I present analyses of optical and X-ray data of early-type galaxies in nearby rich clusters as part of the NOAO Fundamental Plane Survey. Spectroscopic parameters, including linestrengths and velocity dispersions are measured for...
Chlorinated ethenes are ubiquitous environmental pollutants of public concern due to their potential toxicity and carcinogenicity. Under appropriate conditions anaerobic bacteria mediate the dechlorination of perchloroethylene (a common dry...

I tackle the problem of naming and sharing resources across administrative boundaries. Conventional systems manifest the hierarchy of typical administrative structure in the structure of their own mechanism. While natural for communication that...
Cataclysmic variable stars are a broad class of close binary systems in which matter is transferred from a normal secondary star onto a white dwarf. This thesis reports spectroscopy of a number of examples, aimed mostly at clarifying the underlying...
