Undergraduate Honors Theses

Cognitive decline increasingly plague older adults. Although various studies have correlated aerobic exercises with decreased incidence of the development and progression of cognitive deterioration in older adults, there is no evidence as to whether or not the Wii Fit Plus Rhythm Kung-Fu, Hula-Hoop and the Wii Just Dance can improve the cognitive function of older adults as measured by the Standardized Mini Mental State Examination (SMMSE) instrument. A descriptive study design was used to explore the feasibility of implementing an aerobic exercise program for older adults in an assisted living facility using these Wii games, and evaluating whether or not …

Time-Averaged Surrogate Modeling For Small Scale Propellers Based On High-Fidelity Cfd Simulations, Joseph Ray Carroll

Theses and Dissertations

Many Small Unmanned Aerial Vehicles (SUAV) are driven by small scale, fixed blade propellers. The flow produced by the propeller, known as the propeller slipstream, can have significant impact on SUAV aerodynamics. In the design and analysis process for SUAVs, numerous Computational Fluid Dynamic (CFD) simulations of the coupled aircraft and propeller are often conducted which require a time-averaged, steady-state approximation of the propeller for computational efficiency. Most steady-state propeller models apply an actuator disk of momentum sources to model the thrust and swirl imparted to the flow field by a propeller. These momentum source models are based on simplified …

Diffusion Tensor Imaging In Hiv And Hepatitis C Coinfection, Jodi Michelle Heaps

Dissertations

Previous studies have demonstrated that infection with both human immune deficiency virus (HIV) and hepatitis C (HCV) is associated with impaired cognitive function. It is unclear whether co-infection is associated with neuroimaging markers of brain dysfunction. The purpose of the present study was to compare HIV+ individuals, HIV/HCV+ individuals, and seronegative controls using diffusion tensor imaging (DTI) to assess the microstructural integrity of white matter tissue. Methods: Twenty-five HIV+ patients, 25 HIV/HCV+ patients, and 25 seronegative controls matched for age were included in the study. All participants completed an MRI session, neuropsychological testing, and an evaluation of clinical variables including …

Delamination Detection In Concrete Using Disposable Impactors For Excitation, Anjali Narendra Patil

Theses and Dissertations

Delaminations in concrete bridge decks result primarily from corrosion of the reinforcing bars (or rebar). This corrosion leads to volumetric expansion of the rebar. When the rebar expands, concrete cracks, and there is a localized separation of the concrete cover from the underlying concrete. Impact-echo testing is an effective technique to map delaminations on concrete bridge decks. However, mapping speed is limited by necessary retrieval of the impactor for traditional tests. To achieve higher scanning speeds, it is advantageous to use both a non-contact measurement (air-coupled impact-echo) and disposable-impactor excitation. Disposable impactors have the potential advantage of achieving greater deck …

Transmission Shift Map Optimization For Reduced Electrical Energy Consumption In A Pre-Transmission Parallel Plug-In Hybrid Electric Vehicle, Jonathan Dean Moore

Theses and Dissertations

The use of an automatic transmission in pre-transmission parallel hybrid electric vehicles provides greater potential for powertrain optimization than conventional vehicles. By modifying the shift map, the transmission’s gear selection can be adjusted to reduce the energy consumption of the vehicle. A method for determining the optimal shift map for this hybrid vehicle has been implemented using global optimization and software-in-the-loop vehicle simulation. An analysis of the optimization has been performed using software-in-the-loop and hardware-in-the-loop simulation and evaluates two vehicle modes: regenerative braking active and regenerative braking disabled. The results of these two modes illustrate the successful implementation of the …

Modeling Dendritic Solidification Using Lattice Boltzmann And Cellular Automaton Methods, Mohsen Eshraghi Kakhki

Theses and Dissertations

This dissertation presents the development of numerical models based on lattice Boltzmann (LB) and cellular automaton (CA) methods for solving phase change and microstructural evolution problems. First, a new variation of the LB method is discussed for solving the heat conduction problem with phase change. In contrast to previous explicit algorithms, the latent heat source term is treated implicitly in the energy equation, avoiding iteration steps and improving the formulation stability and efficiency. The results showed that the model can deal with phase change problems more accurately and efficiently than explicit LB models. Furthermore, a new numerical technique is introduced …

Drawing Lessons From The U.K. Constitutional Reform Act Of 2005, Terence J. Lau

Management and Marketing Faculty Publications

In this City Square dialogue, Professor Judith Maute provided the initial spark in her important 2007 article on reforms to judicial selection in the United Kingdom.[1] In her article, Professor Maute outlined the breathtaking and daring changes implemented in the U.K. that upended centuries of tradition to modernize and strengthen public confidence in the judiciary. Most significant among these changes were the creation of a Supreme Court and dramatically moving the process of becoming a judge away from a secretive appointment to a professional Judicial Appointments Commission.[2] The reforms eschew direct affirmative action, but place an explicit value on diversity …

A Dynamic Hybrid Rans/Les Modeling Methodology For Turbulent/Transitional Flow Field Prediction, Mohammad Faridul Alam

Theses and Dissertations

A dynamic hybrid Reynolds-averaged Navier-Stokes (RANS)-Large Eddy Simulation (LES) modeling framework has been investigated and further developed to improve the Computational Fluid Dynamics (CFD) prediction of turbulent flow features along with laminar-to-turbulent transitional phenomena. In recent years, the use of hybrid RANS/LES (HRL) models has become more common in CFD simulations, since HRL models offer more accuracy than RANS in regions of flow separation at a reduced cost relative to LES in attached boundary layers. The first part of this research includes evaluation and validation of a dynamic HRL (DHRL) model that aims to address issues regarding the RANS-to-LES zonal …

A Multiple Case Study For Calibrating Acoustic Backscatter To Total Suspended Material In A Large River System, Brittany Lynne Gunkel

Theses and Dissertations

Sediment transport measurements are determined using techniques such as bedmaterial and suspended-sediment sampling, and more recently the conversion of acoustic backscatter (ABS). Acoustic waves scatter and attenuate while passing through a watersediment mixture and the backscatter is converted to sediment concentration, size, and shape. A multiple case study performed using data from West Bay, Old River, and Mississippi River at Vicksburg show the variability of a large river system TSM flux during assorted hydrographs and two methods (CHL and moving boat) capture the events. After processing and applying the two methods the results showed that the methods are typically within …

Differentiation Of Fungal Phytopathogens By Ft-Ir And Maldi-Tof Ms, Curtis Muldrow Atkinson

Theses and Dissertations

The use of matrix assisted laser desorption ionization time-oflight mass spectrometry, Fourier transform infrared spectroscopy, and other analytical means of identifying and differentiating microorganisms hold much promise. These analytical tools have been extensively assessed for their ability to differentiate bacteria and fungi. Most of this research has been coordinated in medically relevant microorganisms, but the technology can work just as well with agriculturally important microorganisms. In this thesis, these technologies were reviewed and then subsequently studied for their ability to differentiate Aspergillus species (that devastate corn and other crops yearly with aflatoxin contamination), as well as Macrophomina phaseolina and Thielaviopsis …

A Comparison Of Participant Gains In Attitude And Behavior After Experiencing A Food Safety Curriculum In Traditional And Computer Delivered Environments, Jennifer Knowles Schilling

Simulation Of The Impact And Solidification Of Super Cooled Water Droplets, Joshua Daniel Blake

Theses and Dissertations

In order to study inlight ice adhesion at the droplet-scale, a strategy is presented to simulate the impact and solidification of a supercooled water droplet on a cooled substrate. Upon impact, nucleation is assumed to occur instantaneously, and properties of the droplet are chosen to account for the nucleation process. Simulations are performed in ANSYS Fluent using a coupled Volume of Fluid and Level-Set method to capture the air-water interface and an Enthalpy-Porosity method to capture the liquid-solid interface. Calibration of a simulation parameter, Amush, is performed in order to match experimental data for different surface types and surface temperatures. …

Strategies For Optimization Of Diesel-Ignited Propane Dual Fuel Combustion In A Heavy Duty Compression Ignition Engine, Chad Duane Carpenter

Theses and Dissertations

A 12.9 L heavy duty compression ignition engine was tested with strategies for dual fuel optimization. The effects of varied intake manifold pressure as well as split-injection strategies at a load of 5 bar BMEP and 85 PES were observed. These results were used to allow testing of split-injection strategies at a higher load of 10 bar BMEP at 70 PES that were void of MPRR above 2000 kPa/CAD. The split-injection strategies at 5 bar BMEP showed that lower BSNOx can be achieved with minimal drop in FCE. Varying intake manifold pressure revealed that combustion occurs earlier in a cycle …

Automatic Modulation Recognition For Aeronautical Telemetry, Jacob William Frogget

Theses and Dissertations

This these explores automatic modulation recognition as applied to PCM/FM, SOQPSK- TG and ARTM CPM. It found that the likelihood based approach is intractable. The statistical features of the amplitude, phase and frequency are ineffective at distinguishing these modulation types. A method based on the phase changes between symbols is developed and shows that as long as symbol timing is established, this method can effectively distinguish PCM/FM, SOQPSK-TG and ARTM CPM for signal-to-noise ratios above 30 dB. Another method, the Bianchi-Loubaton- Sirven technique, was able to distinguish PCM/FM and SOQPSK-TG but was unable to distinguish ARTM CPM. A happy byproduct …

Findings from this study provided insight as to how women prefer receiving information from their health care providers concerning their diagnosis of HPV. …

Hand Hygiene Perceptions Of Student Nurses., Brittany Berger

Undergraduate Honors Theses

Compliance with hand hygiene is widely recognized as the most important factor in preventing transmission of infection to patients in healthcare settings (Haas and Larson, 2007). Hand hygiene dramatically decreases the potential pathogens on hands and is considered the first measure for decreasing the risk of transmitting organisms to patients, healthcare professionals, and family members. Noncompliance with hand hygiene practices has been shown to increase healthcare-associated infections, costing hospitals $35.7-$45 billion each year (Centers for Disease Control and Prevention [CDC], 2012). Education about hand hygiene starts in school and should transfer into the real world of nursing. The purpose of …

Impact Of Oxidative Stress On Female Fertility., Tasha Harris

Undergraduate Honors Theses

This study examined nutritional status and fecundity of women and was approved for patient enrollment by the ETSU Institutional Review Board (IRB). Once enrolled, participants filled out two food frequency questionnaires (FFQ, fruit/vegetable intake, fat intake), self-reported anthropometric data, and had one 5 mL vacutainer of whole blood (EDTA) collected for measures of oxidative stress (OS), coenzyme Q10 level, and fatty acid profile of the red blood cell (RBC) membrane. Participants were either designated to the case group (13 women experiencing fertility problems and an anti-mullerian hormone level of 1 ng/ml or less (AMH, <1 ng/mL)) or the control group (13 women experiencing normal ovulation cycles and no evidence of polycystic disease). This study hypothesized that the case group would have poorer plasma antioxidant status, consume more dietary saturated fat and have lower levels of omega-3 and higher levels of omega-6 fatty acids in the RBC membrane. Results showed that case participants had significantly higher body mass index (BMI) when graduating from high school, BMI upon enrollment in the study, and trended to gain more weight since high school. Antioxidant status of the plasma tended to be higher for the case group. This result was surprising as case participants consumed significantly fewer servings of fruits and vegetables (sources of antioxidants) than control subjects. FFQ results indicated that case participants consumed significantly higher amounts of total fat (g), saturated fat (g), unsaturated fat (g), and their diets had a higher dietary fat percent. No significant differences were noted in the individual fatty acids isolated from the RBC membrane or in calculated ratios of fatty acid between case and control groups. The fatty acid profile from RBC membranes are in agreement with self-reported fat intake from FFQ data and may provide a rationale for no differences observed between the two groups.

The Effect Of The Flipped Classroom Model On Achievement In An Introductory College Physics Course, Joshua Brian Winter

Theses and Dissertations

The flipped or inverted classroom model is one in which the time and place for traditional lecture and homework are reversed. Traditional lecture is replaced by online videos assigned as homework. This frees up time in class to be spent with more student centered activities such as discussion based concept questions and group problem solving. While growing in popularity, research on the effectiveness of this format is sparse. In this quasi-experimental study, two sections of an introductory algebra-based college physics course were examined over a five week period. Each section was taught with either the traditional or flipped model and …
