Use Of Multi-Criteria Decision Analysis With Fuzzy Measures In Historical Gis, Jeanne Marie Jones

Master's Theses

Geographic information systems (GIS) can enhance historical research by providing tools to explore the spatial relationships of locations in historical sources. However, no widespread methods currently exist for translating vaguely defined historical spatial information into GIS data formats and producing a location estimate. Other GIS techniques do exist that can model the necessary process. Multi-criteria decision analysis with fuzzy measures can be applied to vague historical records to approximate location. The Wieslander Vegetation Type Map dataset is used to demonstrate the model effectiveness. Results show that this technique successfully translated written descriptions of location into raster, or grid-based, surfaces within …

Learning Financial Literacy In The Family, Maria Paula Calamato

Master's Theses

This thesis examines the relationship between parental involvement and student level of financial literacy. Past studies have established that children's financial behavior and attitudes are shaped by their parents who pass on norms and social values to them. Using a convenience sample of 108 undergraduate students at a local state university, the present research tested whether children who had higher levels of financial literacy had parents who had taught them financial knowledge. The results of the test show that students' level of financial literacy is not significantly related to parental involvement.

Design And Analysis Of Multistage Cooperative Broadcast With Amplify And Forward Relays, Bhargava Yammanuru

Master's Theses

Cooperative communication achieves spatial diversity by having the transceivers in an ad-hoc network pool their resources at the physical layer and cooperatively transmit their information. For this to be possible without adding a large overhead, we need low overhead-distributed protocols. This thesis proposes one such distributed scheme for wireless ad-hoc networks.

In this work, we study the propagation of the signal in a cooperative network where a single source message is retransmitted by multiple stages (levels) of relays. Relays are assumed to have limited computational abilities and hence adopt the amplify-and-forward scheme. At each node, cooperative diversity is obtained by …

Structure-Function Relationship Studies Of The Udp-Glucose Pyrophosphorylase From Escherichia Coli, Agnieszka Maria Orlof

In plants, UDP-Glc PPase is necessary for sucrose synthesis while mammals utilize this enzyme for the production of glycogen. A bacterium such as Escherichia coli uses UDP-Glc PPase for biosynthesis of the lipopolysscharide core which forms a cell wall.

This study focused on UDP-Glc PPase from Escherichia coli which is encoded by both galU and galF genes. The first part of this project investigated amino acids that could play an important role in the function of UDP Glc PPase (GalU). Based …

Design Techniques To Improve Time Dependent Dielectric Breakdown Based Failure For Cmos Circuits, Emanuel S. Tarog

Master's Theses

This project investigates the failure of various CMOS circuits as a result of Time Dependent Dielectric Breakdown (TDDB) and explores design techniques to increase the mean time to failure (MTTF) of large-scale circuits. Time Dependent Dielectric Breakdown is a phenomenon where the oxide underneath the gate degrades as a result of the electric field in the material. Currently, there are few well documented design techniques that can increase lifetime, but with a tool chain I created called the MTTF Analyzing Program, or MAP, I was able to test circuits under various conditions in order to identify weak links, discover relationships, …

Charge Injection And Clock Feedthrough, Jonathan Yu

Master's Theses

Turning off a transistor introduces an error voltage in switched-capacitor circuits. Circuits such as analog-to-digital converters (ADC), digital-to-analog converters (DAC), and CMOS image sensor pixels are limited in performance due to the effects known as charge injection and clock feedthrough. Charge injection occurs in a switched-capacitor circuit when the transistor turns off and disperses channel charge into the source and drain. The source, which is the sampling capacitor, experiences an error in the sampled voltage due to the incoming channel charge. Simultaneously, the coupling due to gate-source overlap capacitance also contributes to the total error voltage, which is known as …

Numerical Simulation Of Capsule Dissolution In The Usp Apparatus Ii, Jasmine Han

Master's Theses

The capsule is the second most common type of drug dosage form, yet detailed research of capsule dissolution in the USP Apparatus II (a paddle dissolution apparatus that mimics the drug dissolution process in an in vivo environment) is not well reported. In this work, a mathematical model was developed that incorporates both the dissolution of the capsule shell and the slug within the capsule shell. Capsule shell dissolution was modeled with the assumption that the shell undergoes an erosion process only. The capsule slug dissolution model incorporated mass transfer principles, Markov chain theory, and the influence of hydrodynamics on …

Cooperative Symbol-Based Signaling For Networks With Multiple Relays, Yuanyuan Quan

Master's Theses

Wireless channels suffer from severe inherent impairments and hence

reliable and high data rate wireless transmission is particularly challenging to

achieve. Fortunately, using multiple antennae improves performance in wireless

transmission by providing space diversity, spatial multiplexing, and power gains.

However, in wireless ad-hoc networks multiple antennae may not be acceptable

due to limitations in size, cost, and hardware complexity. As a result, cooperative

relaying strategies have attracted considerable attention because of their abilities

to take advantage of multi-antenna by using multiple single-antenna relays.

This study is to explore cooperative signaling for different relay networks,

such as multi-hop relay networks formed …

Emissions And Impacts From Prescribed Fire In A Longleaf Pine Ecosystem, Scott James Strenfel

Characterization Of Protein Residue Surface Accessibility Using Sequence Homology, Radhika Pallavi Mishra

Master's Theses

Residues present on the surface of the proteins are involved in a number of functions, especially in ligand-protein interactions, that are important for drug design. The residues present in the core of the protein provide stability to the protein and help in maintaining protein structure. Hence, there is a need for a binary characterization of protein residues based on their surface accessibility (surface accessible or buried). Such a classification can aid in the directed study of either residue type.

A number of methods for the prediction of surface accessible protein residues have been proposed in the past. However, most of …

Courtship And Copulation In Glaucous-Winged Gulls, Larus Glaucescens, Kelly M. Mcwilliams

Master's Theses

Using video recordings and scan counts, I examined the occurrence, sequences, and durations of behavior and environmental factors associated with courtship and copulation in glaucous-winged gulls, Larus glaucescens. Males and females in a pair had equivalent pre- and post-Mount behavior occurrences and durations. The main courtship sequence was Head Toss -- Courtship Beg/Respond -- Mounted/Mount, and felames appeared to initiate transitions between these pre-Mount behaviors. More Mounts occurred during the egg-laying stage of the breeding season, but copulation duration, wing-flag duration, and cloacal contacts per copulation showed no significant differences across sampling periods. Poisson analysis showed no significant grouping …

The Design And Manufacture Of A Light Emitting Diode Package For General Lighting, Michael S. Krist

Master's Theses

Lighting technologies have evolved over the years to become higher quality, more efficient sources of light. LEDs are poised to become the market standard for general lighting because they are the most power efficient form of lighting and do not contain hazardous materials. Unfortunately, LEDs pose unique problems because advanced thermal management is required to remove the high heat fluxes generated by such relatively small devices. These problems have already been overcome with complex packaging and exotic materials, but high costs are preventing this technology from displacing current lighting technologies.

The purpose of this study is to develop a low-cost …

The Distribution Of Gnrh And Erbeta In Pre- And Post-Pubertal Male Rats, Maysaa Nageeb

Master's Theses

The hypothalamic-pituitary- gonadal axis is intrinsic in regulating reproductive function. Each part orchestrates the synthesis and release of a key hormone. At the level of the hypothalamus, Gonadotropin- releasing hormone (GnRH) is released and it is the

most upstream regulator of sexual maturation. GnRH neurons express a type of estrogen receptor, ERbeta, which suggests that estradiol (E2) plays a direct role in modulating GnRH function (Herbison and Pape 2001). The objective of this study was to determine if gonadal steroid hormones regulate the expression of ERbeta and GnRH mRNA in the male brain during pubertal development. In-situ hybridization was used …

Localization And Functional Analysis Of Plasmodium Falciparum Genes Pfl2550w And Pff0750w, Carolyn Jane Strobel

Master's Theses

Malaria is a parasitic disease that causes over a million deaths worldwide each year. Understanding development through the parasite's life cycle is necessary to stop disease transmission. As the genetic basis for the crucial transition from the erythrocytic asexual cycle to gametocytogenesis is unknown, we hope to better understand this transition by studying sexual stage genes and their roles in gametocytogenesis. PFL2550w and PFF0750w are genes upregulated during gametocytogenesis that were identified by a whole-genome microarray comparing gene expression between gametocyte-producing and gametocyte-deficient strains. In this study, PFL2550w was shown to be a soluble protein that is exported from the …

The Obama Effect And Its Relationship To The Perceptions Of Blacks On Education And Social Mobility, Lydia K. Young

Master's Theses

The educational system in the United States has been characterized as political, a meritocracy (Hurn, 1992), a structure that socializes citizens (Warren, 1996), a system that marginalized those of races marked other or defined as minority by society (Ratvich, 1983; West, 1993; Katz, 1999) and, most importantly for this study, the key to a more equitable society through schooling and personal beliefs and the possibility of lifelong achievement (Anderson, 1988). Our educational system, ever changing and complicated by definition and action, plays a large role in one's perception of the ability of people to achieve social mobility -- especially for …
