Using N-Dimensional Volumes For Mathematical Applications In Spectral Image Analysis, Amanda Ziemann

Theses

The ability to detect an object or activity -- such as a military vehicle, construction area, campsite, or vehicle tracks -- is highly important to both military and civilian applications. Sensors that process multi and hyperspectral images provide a medium for performing such tasks. Hyperspectral imaging is a technique for collecting and processing imagery at a large number of visible and non-visible wavelengths. Different materials exhibit different trends in their spectra, which can be used to analyze the image. For an image collected at n different wavelengths, the spectrum of each pixel can be mathematically represented as an n-element vector. …

Optimal Discrete-In-Time Inventory Control Of A Single Deteriorating Product With Partial Backlogging, Yang Tan

USF Tampa Graduate Theses and Dissertations

The implicit assumption in conventional inventory models is that the stored

products maintain the same utility forever, i.e., they can be stored for an infinite period of

time without losing their value or characteristics. However, generally speaking, almost all

products experience some sort of deterioration over time. Some products have very small

deterioration rates, and henceforth the effect of such deterioration can be neglected.

Some products may be subject to significant rates of deterioration. Fruits, vegetables,

drugs, alcohol and radioactive materials are examples that can experience significant

deterioration during storage. Therefore the effect of deterioration must be explicitly taken

into …

Finite Element Analysis Of Thermoelectric Systems With Applications In Self Assembly And Haptics, Patrick T. Mcknight

USF Tampa Graduate Theses and Dissertations

Micro-scale self assembly is an attractive method for manufacturing sub-millimeter sized thermoelectric device parts. Challenges controlling assembly yield rates, however, have caused research to find novel ways to implement the process while still resulting in a working device. While a typical system uses single n-type and p-type material elements in series, one method used to increase the probability of a working device involves adding redundant parallel elements in clusters. The drawback to this technique is that thermal performance is affected in clusters which have missing elements. While one-dimensional modeling sufficiently describes overall performance in terms of average junction temperatures and …

Neural Coding And Decoding, Alexander Dimitrov

Systems Science Friday Noon Seminar Series

Methods based on Rate Distortion theory have been successfully used to cluster stimuli and neural responses in order to study neural codes at a level of detail supported by the amount of available data. They approximate the joint stimulus-response distribution by quantizing paired stimulus-response observations into smaller reproductions of the stimulus and response spaces. An optimal quantization is found by maximizing an information-theoretic cost function subject to both equality and inequality constraints, in hundreds to thousands of dimensions. This analytical approach has several advantages over other current approaches:

• it yields the most informative approximation of the encoding scheme given the …

Comparison Of Risky Decision Making Processes In Dyads And Individuals, Moumita Mukherjee

USF Tampa Graduate Theses and Dissertations

The thesis compared the likelihood of taking risks in dyads and individuals in

varying situations. Patterns of risky decision making were examined in the standard risky

choice task and a novel risk management task. The relative successes of two theories of

risky decision making were assessed: Prospect Theory emphasizes perceptual and

psychophysical processes, whereas Security-Potential/Aspiration Level Theory

emphasizes dispositional and motivational processes. The thesis also examined dyads’

decision behavior in light of competing social influence perspectives regarding risky

versus cautious shifts and group polarization.

Participants, as individuals or as part of a dyad, made decisions in 23 trials about

hypothetical …

Stereotype Logit Models For High Dimensional Data, Andre Williams

Theses and Dissertations

Gene expression studies are of growing importance in the field of medicine. In fact, subtypes within the same disease have been shown to have differing gene expression profiles (Golub et al., 1999). Often, researchers are interested in differentiating a disease by a categorical classification indicative of disease progression. For example, it may be of interest to identify genes that are associated with progression and to accurately predict the state of progression using gene expression data. One challenge when modeling microarray gene expression data is that there are more genes (variables) than there are observations. In addition, the genes usually demonstrate …

Endothelial Cell Capture Of Heparin-Binding Growth Factors Under Flow, Bing Zhao, Changjiang Zhang, Kimberly Forsten-Williams, Jun Zhang, Michael Fannon

Ophthalmology and Visual Science Faculty Publications

Circulation is an important delivery method for both natural and synthetic molecules, but microenvironment interactions, regulated by endothelial cells and critical to the molecule's fate, are difficult to interpret using traditional approaches. In this work, we analyzed and predicted growth factor capture under flow using computer modeling and a three-dimensional experimental approach that includes pertinent circulation characteristics such as pulsatile flow, competing binding interactions, and limited bioavailability. An understanding of the controlling features of this process was desired. The experimental module consisted of a bioreactor with synthetic endothelial-lined hollow fibers under flow. The physical design of the system was incorporated …

Leveraging Information Technology Within A Roman Catholic Diocese, Sidney K. Rodriguez

Regis University Student Publications (comprehensive collection)

Parishes within the Roman Catholic Church face many of the same concerns as any other non-profit organization. Dependencies on donations and volunteer help restrict the parish to leverage technology to gain efficiencies. Parishes have an additional concern. Although grouped under a Diocese, this hierarchical structure is not a standard, top-down directive organization. A Roman Catholic Diocese is a "subsidiarity". Decisions are made at the lowest level, specifically; decisions on how to operate and administer the parish are given to the pastor or parish director of that parish. Acknowledging that leveraging technology is a way to gain efficiencies, the ability to …

Mutual Elements And Substrate Effect Analysis On Patch Antenna Arrays, Matthew J. Wallace

USF Tampa Graduate Theses and Dissertations

There have been many different technology advancements with the invention of solid state electronics, leading to the digital era which has changed the way users employ electronic circuits. Antennas are no different; however, they are still analog devices. With the advancements in technology, antennas are being fabricated on much higher frequencies and with greater bandwidths, all while trying to keep size and weight to a minimum. Centimeter and millimeter wave technologies have evolved for many different radio frequency (RF) applications. Microstrip patch antennas have been developed, as wire and tubular antenna elements are difficult to fabricate with the tolerances required …

Identification And Optimization Of Classifier Genes From Multi-Class Earthworm Microarray Dataset, Ying Li, Nan Wang, Chaoyang Zhang, Ping Gong

Faculty Publications

Monitoring, assessment and prediction of environmental risks that chemicals pose demand rapid and accurate diagnostic assays. A variety of toxicological effects have been associated with explosive compounds TNT and RDX. One important goal of microarray experiments is to discover novel biomarkers for toxicity evaluation. We have developed an earthworm microarray containing 15,208 unique oligo probes and have used it to profile gene expression in 248 earthworms exposed to TNT, RDX or neither. We assembled a new machine learning pipeline consisting of several well-established feature filtering/selection and classification techniques to analyze the 248-array dataset in order to construct classifier models that …

Vector Measures Without Weak Compactness: Part Iii, Iwo Labuda

Analysis Seminar

The title above refers to a 1955 paper of Bartle, Dunford, and Schwartz 'Weak Compactness and Vector Measures' in which integration of scalar functions with respect to a vector measure was first defined. Vector measures considered in the original paper were Banach space valued and the notion of weak compactness played the key role in the development of the theory. 55 years later, I am happy to report that the theory can be developed without any constraints on the range space (and so the notion of weak topology is not even available, in general). Let �� be a σ-algebra of …

Long Cycles In 3-Connected Graphs With Bounded Degrees, Guantao Chen

Combinatorics Seminar

In 1993 Jackson and Wormald conjectured that if G is a 3-connected n-vertex graph with maximum degree d 2'. 4 then G has a cycle of length O(n10gd-1 2). In this talk, I will report progresses on this conjecture and related problems.

Packing Virtual Machines Onto Servers, David Luke Wilcox

Theses and Dissertations

Data centers consume a significant amount of energy. This problem is aggravated by the fact that most servers and desktops are underutilized when powered on, and still consume a majority of the energy of a fully utilized computer even when idle This problem would be much worse were it not for the growing use of virtual machines. Virtual machines allow system administrators to more fully utilize hardware capabilities by putting more than one virtual system on the same physical server. Many times, virtual machines are placed onto physical servers inefficiently. To address this inefficiency, I developed a new family of …

Tensorial Reconstruction At The Integrand Level, G. Heinrich, Giovanni Ossola, T. Reiter, F. Tramontano

Publications and Research

We present a new approach to the reduction of one-loop amplitudes obtained by reconstructing the tensorial expression of the scattering amplitudes. The reconstruction is performed at the integrand level by means of a sampling in the integration momentum. There are several interesting applications of this novel method within existing techniques for the reduction of one-loop multi-leg amplitudes: to deal with numerically unstable points, such as in the vicinity of a vanishing Gram determinant; to allow for a sampling of the numerator function based on real values of the integration momentum; to optimize the numerical reduction in the case of long …
