Faculty Publications

Single crystals of the lanthanide-containing iridate, disamarium sodium iridium hexaoxide, Sm₂NaIrO₆, were prepared via high-temperature flux growth and structurally characterized by single-crystal X-ray diffraction. The compound crystallizes in the monoclinic space group P2₁/n and is a double perovskite, consisting of a 1:1 ordered rock-salt-type lattice of corner-shared NaO₆ and IrO₆ distorted octahedra. Samarium occupies the eightfold coordination site generated by the connectivity of the octahedra.

An Architecture Design For A Real-Time Web-Based Visualization In The Grid Environment, Bhargavi Sura

Theses and Dissertations

Situations like war, terrorist attacks, fire accidents, floods, storms, etc., which threaten human life and property, demand immediate action to decrease the damage caused by them. A system is needed that predicts the future events based on what has happened and notifies the concerned personnel. The situation could be better understood in less time if the data is represented as colored, shaded and moving images rather than as numbers. Such a system requires a real-time Web-based visualization system with easy and secure access to grid resources, presenting easy-to-read graphics through a simple interface provided by a Web browser, and responding …

An In Vitro Evaluation Of Chitosan As A Biomaterial Focusing On The Effects Of The Degree Of Deacetylation, Virginia Hamilton

Theses and Dissertations

The material characteristics play a role in the suitability of chitosan for biomedical applications. This is not surprising since the degree of deacetylation of chitosan influences antimicrobial activity, degradation rate, immune reaction and mechanical properties such as strength and elongation. This study examines chitosans of variable material characteristics for wound and bone healing applications. Chitosan films of 76, 78, 80, 87, 91, 92, and 95% degree of deacetylation were tested in vitro for cellular responses by fibroblast and bone cell lines. The in vitro responses were compared to the material characteristics of molecular weight, degree of deacetylation, swelling index, and …

A Sliding Interface Method For Unsteady Unstructured Parallel Flow Simulations, Eric Lindsay Blades

Theses and Dissertations

The primary objective of this study is to develop a sliding interface method for simulations involving relative rotational grid motion suitable for unstructured grid topologies. The present method alleviates computationally expensive grid deformation, remeshing, and hole cutting procedures. Rotational motion is accomplished by rigidly rotating a subdomain representing the moving component. At the subdomain interface boundary, the faces along the interfaces are extruded into the adjacent subdomain to create new volume elements and provide a one-cell overlap. These new volume elements close the control volumes for the nodes on the interface surface and allow a flux to be computed across …

Development Of A Distributed Model For The Biological Water Processor Of The Water Recovery System For Nasa Advanced Life Support Program, Sachin Vishwas Puranik

Towards A Methodology For Interactive Virtual Design Assessment, Kang Li

Theses and Dissertations

Complex interactive behaviour involves cognitive, sensation and motor behaviour and may consist of several sub interactive behaviours. It needs to be examined from different points of view. Although explaining everything in one model is not currently possible, it is possible to connect information from different sources to get a better understanding of the interaction to benefit product design. The long-term objective of our study is to develop a methodology for interactive virtual design assessment to study the interactive behaviour and achieve compatibility. This study summarized two experiments which covered many aspects of interactive behaviours in seated posture. Experiment one addressed …

The Creation Of Boron Deep Levels By High Temperature Annealing Of 4h-Sic, Hrishikesh Das

Theses and Dissertations

Creation of semi-insulating layers in SiC is highly desirable for high voltage device fabrication. Specifically PiN diodes can be fabricated with a compensated semi-insulating layer that would be capable of blocking a large reverse voltage. Semi-insulating (SI) behavior in SiC has been traditionally achieved via passivation of shallow dopants with vanadium-related deep levels. Degraded electrical properties of SiC devices result from the use of vanadium compensated SiC because unintentional formation of additional defects due to vanadium segregation and stress generation in the material occur. In this work, the possibility of low doped or SI epilayers via engineering of the boron …

Gml Represntation For Interoperable Spatial Data Exchange In A Mobile Mapping Application, Venu Madhav Singh Kanaparthy

Theses and Dissertations

Geographic information is critical to GIS applications located remotely for executing business operations. GIS applications need to interoperate to be able to share information for analysis and decision making process. Heterogeneity and complexity of information models and structures limit the data flow and application interoperation. Advancements in Internet technologies provided new opportunities for delivering spatial information to remote users. However, spatial data delivered is in proprietary structures, limiting the utility to GIS applications. To enable information flow between GIS applications a portable data modeling approach is necessary. However, geographic information is inherently complex to model. A comprehensive and standardized vocabulary …

Improved Estimation Of Epitaxial Thin Film Thickness And Doping Using Fourier Transform Infrared Reflection Spectroscopy, Swapna Geetha Sunkari

Theses and Dissertations

Film thickness, free carrier concentration and free carrier mobility are critical figures of merit for silicon carbide epitaxial growth. Room temperature Fourier Transform Infrared (FTIR) reflection spectroscopy can estimate these parameters non-destructively and is capable of high-resolution wafer mapping. Commercially available equipment has greatly simplified the application of this technique by coupling a high performance automated spectrometer with model-based data analysis and interpretation based on the personal computer. While powerful numerical techniques run fast and efficient on modern computers, it is essential that low-order, well-conditioned models are needed. The observed reflectance spectrum is the result of reflection and refraction of …

Theoretical Modeling Approach For A Common Residential Electrically Heated Oven And Proposed Oven Design Modification, Mark Allan Breen

Theses and Dissertations

Current research has developed a fully predictive model of an electrically heated common residential oven. This system was modeled using a fully explicit approach and, where applicable, considered natural convective correlations, various radiation networks, and conduction relations. Two oven configurations were modeled, a conventional (unmodified) residential oven and a modified design. By comparing the theoretical results obtained through modeling with experimental results, verification of the modeling assumptions and results has been achieved. This research has produced an analytical design tool for predictive modeling of time dependant surface temperatures, maximum expected temperatures, and the baking performance of various oven designs. Thus …

Common Injuries Of Musicians, Lynette Lukomski

Honors Theses

Musicians face many challenges throughout their careers; dealing with an injury should not be one of them. Unfortunately, studies show that up to seventy-five percent of musicians suffer playing-related injuries. These injuries can retard musical growth, can take time out of practices and performances, and may cost a musician his/her job. Fortunately, many non-invasive treatments can be used if injuries are diagnosed quickly, and prevention techniques are available to prevent an injury from ever occurring. Factors such as age and genetics (physical and mental characteristics inherited from parents) should be considered as well when a musician decides his/her practice schedule. …

Site-Specific Prediction And Measurement Of Cotton Fiber Quality, Rui Wang

Theses and Dissertations

Maintaining cotton fiber quality is crucial for the survival of the U.S. cotton industry. Previous studies have indicated that spatial variability of fiber quality parameters exists in cotton fields. If site-specific measurement and prediction of quality is possible, then fiber could be segregated during the harvesting process, thus increasing the overall price a producer would receive for his crop. Because of the importance of fiber micronaire to the textile industry, the fact that micronaire exhibits moderate variation in the field, and the fact that it has been shown to be related to optical properties of cotton fibers, micronaire measurement was …

Comparing Spectral-Object Based Approaches For Extracting And Classifying Transportation Features Using High Resolution Multi-Spectral Satellite Imagery, Sunil Reddy Repaka

Theses and Dissertations

Recent developments in commercial satellite products have resulted in a broader range of high quality image data, enabling detailed analysis. Transportation features have historically been difficult to accurately identify and structure into coherent networks; prior analyses have demonstrated problems in locating smaller features. One problem is that roadways in urban environments are often partly obscured by proximity to land cover or impervious objects. Ongoing research has focused on object-based methods for classification and different segmentation techniques key to this approach. For this application, software packages such as eCognition have shown encouraging results in assessing spatial and spectral patterns at varied …

Ecological And Genetic Consequences Of Seasonal Drought On Stream Communities Inhabiting Pool Refugia, Joseph William Love

Theses and Dissertations

In intermittent streams, hydrological variation is probably the single-most important factor affecting fish assemblage structure. While the response of aquatic assemblages to seasonal or annual variation in hydrology is well-known, less attention has been devoted to how assemblages respond to natural, intraseasonal drought. To explore this question, I conducted summer surveys of fish and aquatic insect assemblages occupying pool refugia in first to third order, intermittent streams in the Saline river drainage in the Ouachita highlands (central Arkansas, U.S.A.)(2001?2003). The goals of this project were: 1) to relate assemblage variability of fishes and aquatic insects to environmental gradients during summer …

Distributed Generation Impact On Fault Response Of A Distrubution [I.E., Distribution] Network, Venkata Ramanujam Kanduri

Theses and Dissertations

Electric power systems are a key infrastructure today. Power systems can be divided into three major parts: generation, transmission, and distribution. Out of these the distribution system is the most complex part and least studied system. In order to have continuous and reliable power to all customers it is necessary to have a good protection system. Major disturbances that are caused and last for a very short duration are called faults. With the advent of distributed generation (DG), the understanding of fault response has become more difficult. This thesis presents the study of the fault response and the factors that …

Analysis Of The Design And Operation Of Mix-Bank Resequencing Areas, Arunkumar Subramanian

Theses and Dissertations

Automotive assembly plants work on a pre-planned job sequence in order to optimize the performance of the assembly line. However, the job sequence becomes scrambled due to factors such as plant layout, process design, variability and uncertainty. Assembly plants use either a mix-bank or an automatic storage and retrieval system to regenerate the sequence before final assembly. A mix-bank, which is a set of parallel lanes, is the most common method used in the automotive industry to reconstruct the sequence. Only the first vehicles on the lanes are available for sequencing in a mix-bank set-up. Hence the lane selection policy …

A newly designed ICP torch was presented. Limits of detection were measured for elemental mercury, both in an ICP as well as in a cold mercury chemical generator. The efficiency of the technique was compared with laser-induced fluorescence (LIF) in the ICP. Isotopically resolved spectra of uranium were collected with this technique and results were compared to previous studies using LIF. Gas temperature and electron density estimations were done by lineshape measurements on lead atoms in the ICP. …

Investigation Of Order Parameters And Critical Coupling For The Peierls Extended Hubbard Model At One-Quarter Filling, Rahul Padmakar Hardikar

Theses and Dissertations

The determination of the phase boundary between the charge density wave and the Luttinger Liquid phase for the one-dimensional Peierls extended Hubbard model is done using Stochastic Series Expansion and comparison is done with the phase boundary for the Extended Hubbard model. The result of adding an electron-phonon interaction is that the charge density wave phase weakens. par The energy autocorrelation time is reported for the Extended Hubbard Model and the Peierls Hubbard Model. For coupling near and above the critical coupling the autocorrelation time increases exponentially. par Also investigated is the presence of a spin gap and the critical …

Gas Hydrates To Capture And Sequester Co2, Tao Ding

Theses and Dissertations

Reducing atmospheric CO2, a main source of greenhouse gas, has been accentuated recently. One focus is capture, separation, and sequestration of industrial CO2. As a hydrate former, CO2 forms hydrates at moderate temperatures and pressures. This phenomenon could be utilized to capture and separate CO2 from flue gases, and also has the potential to sequester CO2 in the deep sds. This research investigated the CO2-N2 separation efficiency of gas hydrates; it investigated the sequestration potential of CO2 hydrates in ocean sediments. The catalytic effect of surfactants in these processes was investigated. A fluorosurfactant FS-62 was mixed with SDS at 100ppm/1000ppm …

Atmospheric Circulation And Cyclone Frequency Variations Linked To The Primary Modes Of Greenland Snow Accumulation, Jeffrey C. Rogers, Deborah J. Bathke, Ellen Mosley-Thompson, Sheng-Hung Wang

School of Natural Resources: Faculty Publications

Data from 34 Greenland firn cores, extending from 1982 to 1996, are used to identify spatial accumulation variability patterns and their associated atmospheric circulation and cyclone frequencies. The first principal component, representing west-central Greenland accumulation, is correlated to NAO variability, having increased southwesterly (northeasterly) flow over that area during high (low) accumulation winters. The flow is linked to a relative increase in cyclone activity on the west central region of the ice sheet during high accumulation periods. The second principal component represents accumulation over southeastern Greenland where strong westerly flow leads to high accumulation and an increase in lee cyclones …
