Membership Functions For A Fuzzy Relational Database: A Comparison Of The Direct Rating And New Random Proportional Methods, Shweta Sanghi

Theses and Dissertations

Fuzzy relational databases deal with imprecise data or fuzzy information in a relational database. The purpose of this fuzzy database implementation is to retrieve images by using fuzzy queries whose common-language descriptions are defined by the consensus of a particular user community. The fuzzy set, which is presentation of fuzzy attribute values of the images, is determined through membership function. This paper compares two methods of constructing membership functions, the Direct Rating and New Random Proportional, to determine which method gives maximum users satisfaction with minimum feedback from the community. The statistical analysis of results suggests the use of Direct …

Meta-Analysis Of Open Vs Closed Surgery Of Mandibular Condyle Fractures, Marcy Lauren Nussbaum

Theses and Dissertations

A review of the literature reveals a difference of opinion regarding whether open or closed reduction of condylar fractures produces the best results. It would be beneficial to critically analyze past studies that have directly compared the two methods in an attempt to answer this question. A Medline search for articles using the key words 'mandibular condyle fractures' and 'mandibular condyle fractures surgery' was performed. The articles chosen for the meta-analysis contained data on at least one of the following: postoperative maximum mouth opening, lateral excursion, protrusion, deviation on opening, asymmetry, and joint pain or muscle pain. Several common statistical …

Isolation Of Legionella Pneumophila From Well-Maintained Emergency Showers And Eyewash Stations, Jessica Mae Myers

Theses and Dissertations

Legionella pneumophila is a gram-negative bacterium responsible for Legionnaire's disease, and is commonly transmitted via aerosolized water. Legionella colonization of emergency eyewash and shower stations may pose an exposure hazard to users of these stations. There is little information about the role of these stations as significant reservoirs for Legionella. Samples were collected from 67 stations in an industrial facility. At the time of this study, the stations within this facility were under a routine maintenance program that included at least monthly flushing. This study also included the analysis for other bacterial organisms to determine an association between the presence …

Bayesian Analysis, Endogenous Data,And Convergence Of Beliefs, Andrew T. Foerster

Theses and Dissertations

Problems in statistical analysis, economics, and many other disciplines often involve a trade-off between rewards and additional information that could yield higher future rewards. This thesis investigates such a trade-off, using a class of problems known as bandit problems. In these problems, a reward-seeking agent makes decisions based upon his beliefs about a parameter that controls rewards. While some choices may generate higher short-term rewards, other choices may provide information that allows the agent to learn about the parameter, thereby potentially increasing future rewards. Learning occurs if the agent's subjective beliefs about the parameter converge over time to the parameter's …

Improving Student Art Vocabulary Retention, Michelle Bena Mckenna

Theses and Dissertations

The purpose of this investigation was to research vocabulary strategies that could help improve student art vocabulary retention. The subjects were five intact 3rd grade classes at a culturally diverse elementary school outside of Washington, DC. The vocabulary strategies, concept wheel and semantic mapping, were modified and incorporated into a string printmaking unit for two of the five classes. The remaining three classes were taught the same printmaking unit, with the exclusion of the modified vocabulary activities. The results of a labeling assessment given to each class on three separate occasions indicate that the incorporation of vocabulary activities does help …

Copyright And Open Access: Reconsidering University Ownership Of Faculty Research, Robert C. Denicola, Robert C. Denicola

Nebraska Law Review

In 2001, a group of prominent scientists urged a boycott of scholarly journals that refused to provide free online access to research articles within six months after publication. In an open letter to colleagues they pledged to "publish in, edit or review for, and personally subscribe to only those scholarly and scientific journals" that complied with their demand. They defended their stand with the proposition that "[a]s scientists, we are particularly dependent on ready and unimpeded access to our published literature, the only permanent record of our ideas, discoveries, and research results, upon which future scientific activity and progress are …

Numerical Modeling Of Deformations Caused By Carbon Dioxide Sequestration In Coal Seams, Xiaochao Tang

Graduate Theses, Dissertations, and Problem Reports (ETD)

Atmospheric concentrations of CO2, as the most prevalent greenhouse gas, have been dramatically increased due to the anthropogenic emission mainly from fuel combustion. Geologic sequestration of CO2 in coal seams is an attractive choice to mitigate global CO2 emissions and its consequences. It can also provide secondary benefits such as enhanced coalbed methane production.;Three coal sites from Appalachian basin and Black Warrior basin were selected to numerically study the effects of CO2 injection in coal seams on overburden deformations. Finite element method was used for the analysis of overburden response. The analysis consisted of two phases---CO 2 injection and pore …

Shoeprint Analysis: A Gis Application In Forensic Evidence, Michael Anthony Walnoha Jr.

Graduate Theses, Dissertations, and Problem Reports (ETD)

The overall intent of this study is to illustrate how GIS and crime mapping methods can be applied to forensic evidence to better understand and comprehend spatial patterns that exist in these data. This study bridges common crime mapping principles such as hot spot mapping, exploratory data analysis, and spatial statistics to spatial forensic evidence investigation. In particular, forensic shoeprint evidence is examined and spatial relationships are analyzed using both exploratory and confirmatory statistical analysis. It is found that crime mapping principles can be indirectly related to shoeprint evidence mapping. Exploratory spatial data analysis is extremely helpful in breaking up …

Asymptotic Solutions Of Almost Diagonal Differential And Difference Systems, Fei Xue

Graduate Theses, Dissertations, and Problem Reports (ETD)

New methods for both asymptotic integration of the linear differential systems Y'(t) = [D( t) + R(t)]Y( t) and asymptotic summation of the linear difference systems Y(t + 1) = [D(t)+ R(t)]Y(t) are derived. The fundamental solution Y(t) = phi( t)[I+P(t)] for differential and difference systems is constructed in terms of a product. The first matrix function phi(t) is decided by the diagonal matrix D(t) and the second matrix I + P(t) is a perturbation of the identity matrix I. Another fundamental solution Y( t) = [I + Q(t)]phi( t) is also constructed for difference systems. Conditions are given on …

Development Of A Small Separation Riser For Fine Coal Particles, Haroon Akhtar

Graduate Theses, Dissertations, and Problem Reports (ETD)

The wet, density based, separation processes employed at the coal preparation plant do not deal with particles under the size of 150 micrometers, resulting in the waste of precious coal resources. An exploratory fluidized bed riser system was developed to separate pyrite from fine coal particles under 150 micrometers in diameter. Gas velocity U0 and solid mass flux G p were the controlled variables so that the flow pattern within the riser was in the transition region from fast fluidization to dilute regime. Nine tests were conducted using coal and nine tests were conducted using a mixture of 10% iron …

Some New Methods For Image Compression, Muhammad Aslam

Graduate Theses, Dissertations, and Problem Reports (ETD)

The vanishing moment of wavelets and associated multi-resolution framework yield an efficient representation of smooth functions with wavelet approximation. However as pointed out in many papers, the similar result cannot be expected for the piecewise smooth functions with large jumps. In other words, wavelet approximation cannot achieve the same approximation order in the vicinity of jumps as in the smooth regions. Large wavelet coefficients associated with jumps are generated and consequently produce oscillations near discontinuities in the reconstructed signal. This is the so-called Gibbs phenomenon or a Ringing effect. In this thesis, we develop a technique which reduces the Gibbs …

Examining Problem-Solving Interpretations: The Role Of Age, Sex, And Femininity, Jennifer A. Flinn

Graduate Theses, Dissertations, and Problem Reports (ETD)

The current study examined age and sex differences in communal interpretations (statements focusing on the needs of others), and whether participants' femininity mediated these differences. One hundred and ninety six participants, 121 younger adults (M=19.26, SD=131: 53 M, 68 F) and 75 older adults (M=73.74, SD=7.65: 36 M, 39 F), were given a vignette regarding a hypothetical job relocation problem that involved either a male or female protagonist. To assess interpretations, participants were asked to indicate all the issues to be considered. The degree to which interpretations reflected communal concerns was coded. Results showed that women had higher communal interpretation …

Relationship Between Damper Resistance And Damper Insertion Depth, Ranjit Jangam

Graduate Theses, Dissertations, and Problem Reports (ETD)

Experiments were performed to determine a predictive model for sliding gate damper resistance (Xdamper). Independent variables included eight ratios of insertion depth (I) to duct diameter (D), two different values of D, four different levels of air velocity, two damper orientations, and two damper edges (Concave/Straight). Analysis of Log (Xdamper) values showed a highly linear relationship with I/D and high statistical significance (p<0.05) for all independent variables and for most two-way interactions. Nearly the entire regression model (R2 = 0.985) was explained by I/D, so all but I/D and Edge were dropped from the final model: Y Log(Xdamper) = -1.434 + 0.089*(Edge) + 4.30*( I/D) (R2 = 0.978). The resulting predictive model: Xdamper = 0.037*10(0.089*(Edge )+4.3*I/D). However error for untransformed Xdamper increased sharply with increasing (I/D) and percent errors were as high as 125% across all values of (I/D). Hence the predictive models are useful for only initial rough adjustment and should be followed by final trial and error adjustment to goal air flow.

Fast Time-Varying Dispersive Channel Estimation And Equalization For 8-Psk Cellular System, Sang-Yick Leong, Jingxian Wu, Chengshan Xiao, Jan C. Olivier

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, a novel channel-estimation scheme for an 8-PSK enhanced data rates for GSM evolution (EDGE) system with fast time-varying and frequency-selective fading channels is presented. via a mathematical derivation and simulation results, the channel impulse response (CIR) of the fast fading channel is modeled as a linear function of time during a radio burst in the EDGE system. Therefore, a least-squares-based method is proposed along with the modified burst structure for time-varying channel estimation. Given that the pilot-symbol blocks are located at the front and the end of the data block, the LS-based method is able to estimate …

Ultrawideband (UWB) is one of the promising technologies for future short-range high data rate communications (e.g. for wireless personal area networks) and longer range low data rate communications (e.g. wireless sensor networks).Despite its various advantages and potentials (e.g. low-cost circuitry, unlicensed reuse of licensed spectrum, precision ranging capability etc.), UWB also has its own challenges. The goal of this dissertation is to identify and address some of those challenges, and provide a framework for practical UWB transceiver design.In this dissertation, various modulation options for UWB systems are reviewed in terms of their bit error rate (BER) performances, spectral characteristics, modem …

Ventricle Slice Detection In Mr Images Using Hough Transform And Object Matching Techniques, Chintan Thakkar

USF Tampa Graduate Theses and Dissertations

The determination of the center slice, defined as a slice through the lateral ventricles in the axial plane in a volume of MR images is important to the segmentation of the image into its anatomical parts. The center or ventricle slice in a set of MR images is recognized by the shape of the ventricles in the axial plane as depicted by the cerebro-spinal fluids in the image. Currently, no technique exists to detect this slice and the purpose of this thesis is to find a slice through the lateral ventricles in the axial plane from a volume of MRI …

Cool White Dwarfs In The Sloan Digital Sky Survey, Mukremin Kilic, Jeffrey A. Munn, Hugh C. Harris, James W. Liebert, Ted Von Hippel, Kurtis A. Williams, Travis S. Metcalfe, D. E. Winget, Stephen E. Levine

Publications

A reduced proper motion diagram utilizing Sloan Digital Sky Survey (SDSS) photometry and astrometry and USNO-B plate astrometry is used to separate cool white dwarf candidates from metal-weak, high-velocity, mainsequence Population II stars (subdwarfs) in the SDSS Data Release 2 imaging area. Follow-up spectroscopy using the Hobby-Eberly Telescope, the MMT, and the McDonald 2.7 m telescope is used to demonstrate that the white dwarf and subdwarf loci separate cleanly in the reduced proper motion diagram and that the contamination by subdwarfs is small near the cool white dwarf locus. This enables large, statistically complete samples of white dwarfs, particularly the …
