Hybrid Sol–Gel Glasses With Glass-Transition Temperatures Below Room Temperature, Andrei Jitianu, Guadalupe Gonzalez, Lisa C. Klein

Publications and Research

Melting gels are hybrid gels that have the ability to soften and flow at around 100 ° C for some combinations of mono- and di-substituted alkoxysiloxanes, where substitutions are either all aromatic or all aliphatic. In this study, melting gels were prepared using phenyltriethoxysilane (PhTES) and dimethyldiethoxysilane (DMDES), meaning both an aromatic and aliphatic substitution. Differential scanning calorimetry was performed to identify glass-transition temperatures, and thermal gravimetric analysis coupled with differential thermal analysis (TGA-DTA) was performed to measure weight loss. The glass-transition temperatures ( T g ) ranged from – 61 ° C to + 5.6 ° C, which are …

Salad: A Multimodal Approach For Contextual Video Advertising, Chen Xiang, Tam Nguyen, Mohan Kankanhalli

Computer Science Faculty Publications

The explosive growth of multimedia data on Internet has created huge opportunities for online video advertising. In this paper, we propose a novel advertising technique called SalAd, which utilizes textual information, visual content and the webpage saliency, to automatically associate the most suitable companion ads with online videos. Unlike most existing approaches that only focus on selecting the most relevant ads, SalAd further considers the saliency of selected ads to reduce intentional ignorance. SalAd consists of three basic steps. Given an online video and a set of advertisements, we first roughly identify a set of relevant ads based on the …

The Development Of An All Quadrilateral Boundary Conforming Grid Generator For High Order Finite Element Methods, Mary A. Barker

Masters Theses and Doctoral Dissertations

A grid generator is developed that produces all quadrilateral meshes. The scheme is automated to work for arbitrary choice of geometry. In addition, a Non-Uniform Rational B-Spline curve fitter is implemented to replicate the curvature of the geometries. The grid elements on the boundaries conform to the curved structure to support high order accuracy for a finite element scheme. Various geometries are used to test the robustness and generality of the meshing algorithm. The initial problems that were encountered are discussed and the solutions explained. The speed of the algorithm is discussed together with the effect of grid and geometry …

A Parabolized Navier-Stokes Method For Wind Farm Applications, Anshul Mittal

Masters Theses and Doctoral Dissertations

Fluid flow simulations play an important role in the wind industry. With the development of large wind farms, flow simulations through an entire wind farm are becoming a necessity. These are required for designing the layout of new wind farms in the development stage and for forecasting power production from the existing ones for operational purposes. Conventional Navier-Stokes simulations (commonly referred to as CFD simulations) are computationally very expensive since they require a supercomputer with runtimes of several weeks. A Parabolized Navier-Stokes (PNS) method is developed and implemented in this study. The developed PNS method requires less stringent approximations as …

Utilizing Monte Carlo Simulations To Optimize Institutional Empiric Antipseudomonal Therapy, Sarah J. Tennant, Donna R. Burgess, Jeffrey M. Rybak, Craig A. Martin, David S. Burgess

Pharmacy Practice and Science Faculty Publications

Pseudomonas aeruginosa is a common pathogen implicated in nosocomial infections with increasing resistance to a limited arsenal of antibiotics. Monte Carlo simulation provides antimicrobial stewardship teams with an additional tool to guide empiric therapy. We modeled empiric therapies with antipseudomonal β-lactam antibiotic regimens to determine which were most likely to achieve probability of target attainment (PTA) of ≥90%. Microbiological data for P. aeruginosa was reviewed for 2012. Antibiotics modeled for intermittent and prolonged infusion were aztreonam, cefepime, meropenem, and piperacillin/tazobactam. Using minimum inhibitory concentrations (MICs) from institution-specific isolates, and pharmacokinetic and pharmacodynamic parameters from previously published studies, a 10,000-subject Monte …

Generalized Techniques For Using System Execution Traces To Support Software Performance Analysis, Thelge Manjula Peiris

Open Access Dissertations

This dissertation proposes generalized techniques to support software performance analysis using system execution traces in the absence of software development artifacts such as source code. The proposed techniques do not require modifications to the source code, or to the software binaries, for the purpose of software analysis (non-intrusive). The proposed techniques are also not tightly coupled to the architecture specific details of the system being analyzed. This dissertation extends the current techniques of using system execution traces to evaluate software performance properties, such as response times, service times. The dissertation also proposes a novel technique to auto-construct a dataflow model …

Modification Of Cellular Dna By Synthetic Aziridinomitosenes, Chris M. Mallory, Ryan P. Carfi, Sangphil Moon, Kenneth A. Cornell, Don L. Warner

Chemistry and Biochemistry Faculty Publications and Presentations

Two synthetic aziridinomitosenes (AZMs), Me-AZM and H-AZM, structurally related to mitomycin C (MC) were evaluated for their anticancer activity against six cancer cell lines (HeLa, Jurkat, T47D, HepG2, HL-60, and HuT-78) and tested for their DNA-modifying abilities in Jurkat cells. Cytotoxicity assays showed that Me-AZM is up to 72-fold and 520-fold more potent than MC and H-AZM, respectively. Me-AZM also demonstrated increased DNA modification over MC and H-AZM in alkaline COMET and Hoechst fluorescence assays that measured crosslinks in cellular DNA. Me-AZM and H-AZM treatment of Jurkat cells was found to sponsor significant DNA-protein crosslinks using …

Quiet-Sun Network Bright Point Phenomena With Sigmoidal Signatures, David L. Chesney, Hakeem M. Oluşeyi, Norton Brice Orange, Patrick R. Champey

Aerospace, Physics, and Space Science Faculty Publications

Ubiquitous solar atmospheric coronal and transition region bright points (BPs) are compact features overlying strong concentrations of magnetic flux. Here, we utilize high-cadence observations from the Atmospheric Imaging Assembly on board the Solar Dynamics Observatory to provide the first observations of extreme ultraviolet quietSun (QS) network BP activity associated with sigmoidal structuring. To our knowledge, this previously unresolved fine structure has never been associated with such small-scale QS events. This QS event precedes a bi-directional jet in a compact, low-energy, and low-temperature environment, where evidence is found in support of the typical fan-spine magnetic field topology. As in active regions …

Interpreting Unique Colloidal Response Of Tio2 Nanomaterials To Controlled Sonication For Understanding Their Assembly Configuration, Siyang Wu

Earth & Environmental Sciences Theses - Archive

It is important to determine the assembly configuration of engineered nanomaterials (ENMs) particularly between aggregate or agglomerate because the assembly configuration greatly influences their fate and transport behavior in the aquatic environment. Aggregated particles are more subject to segregation upon changes of environmental conditions (vice versa) than agglomerated particles. As a strategic tool for investigating the time-resolved reversible segregating and assembling behavior of ENMs and thus estimating their assembly configuration, controlled sonication process was proposed. It was hypothesized the unique colloidal response of ENMs to sonication, with respect to changes in size, might be their intrinsic property associated with assembly …

Earth & Environmental Sciences Theses - Archive

The Early Pennsylvanian Marble Falls Formation in the Fort Worth Basin (FWB) of North-Central Texas was deposited in a broad carbonate ramp system during the initial stages of Ouachita orogenesis. It extends across an area of more than 15,000 square miles and comprises an assortment of facies that vary considerably across the region due to high-frequency sea-level fluctuations. The Marble Falls has been studied extensively in outcrop around the periphery of the Llano Uplift where it was informally divided into lower and upper members separated by a regional unconformity representing the Morrowan-Atokan boundary. A sequence of the Marble Falls Formation …

Developing A System To Arrest Transformation Using A Zebrafish Model For Melanomagenesis, Cory Haluska

Theses, Dissertations and Culminating Projects

The recent emergence of RNA-guided CRISPR-Cas9 gene editing system adapted from the natural defense mechanism found in bacteria and archaea has made the manipulation of genetic loci more feasible than ever. Using this technique we attempted to eliminate a target sequence of about 20 nucleotides from the promoter of the protein ICER (Inducible cAMP Early Repressor) located just upstream of the start sequence. ICER is a small transcription factor and supposed tumor suppressor protein that comes from the CREM (cAMP Responsive Element) gene. ICER has been found to be absent in tumor cells, marked for degradation by the ubiquitin-proteasomal pathway. …

Retention Of Community College Students In Online Courses, Sarah Krajewski

Dissertations

The issue of attrition in online courses at higher learning institutions remains a high priority in the United States. A recent rapid growth of online courses at community colleges has been instigated by student demand, as they meet the time constraints many nontraditional community college students have as a result of the need to work and care for dependents. Failure in an online course can cause students to become frustrated with the college experience, financially burdened, or to even give up and leave college. Attrition could be avoided by proper guidance of who is best suited for online courses. This …

Rank Based Procedures For Ordered Alternative Models, Yuanyuan Shao

Dissertations

The ordered alternatives in a one-way layout with k ordered treatment levels are appropriate for many applications, especially in psychology and medicine. There is extensive literature in this area, and many parametric and nonparametric approaches have been introduced. Abelson-Tukey (AT) test is a frequently used parametric method. Its coefficients provide an ideal way of combining means for the purpose of detecting a monotonic relationship between the independent and dependent variables. The AT method, though, is not robust. Furthermore, our initial empirical studies show that it is not more powerful than the Jonckheere-Terpstra (JT) and the Hettmansperger- Norton (HN) nonparametric tests …

Infrasound From Volcanic Rockfalls, Jeffrey B. Johnson, Timothy J. Ronan

CGISS Publications and Presentations

Proximal infrasound arrays can robustly track rapidly moving gravity-driven mass wasting, which occurs commonly at erupting volcanoes. This study reports on detection, localization, and quantification of frequent small rockfalls and infrequent pyroclastic density currents descending the southeast flanks of Santiaguito’s active Caliente Dome in January of 2014. Such activities are identified as moving sources, which descend several hundred meters at bulk flow speeds of up to ~10 m/s, which is considerably slower than the descent velocity of individual blocks. Infrasound rockfall signal character is readily distinguishable from explosion infrasound, which is manifested by a relatively fixed location source with lower …

Battery Energy Storage System: A Financial Analysis For Microgrids, Nikitas Zagoras

All Theses

Renewable Energy Sources are becoming more popular mostly due to their reduced carbon footprint. One major issue that keeps them from becoming more popular is their output variability. Energy Storage Systems have been gaining a lot of “traction” into the power grid since they can address that variability and make RES more controllable. In this thesis, various Energy Storage Systems are introduced, while Battery Energy Storage Systems and their various technologies are studied in more detail. BESS are commonly used in supporting Photovoltaic Power Plants, as they provide the convenience of a shared DC bus. This thesis also includes an …

Estimation On Gibbs Entropy For An Ensemble, Lekhya Sai Sake

Electronic Theses, Projects, and Dissertations

In this world of growing technology, any small improvement in the present scenario would create a revolution. One of the popular revolutions in the computer science field is parallel computing. A single parallel execution is not sufficient to see its non-deterministic features, as same execution with the same data at different time would end up with a different path. In order to see how non deterministic a parallel execution can extend up to, creates the need of the ensemble of executions. This project implements a program to estimate the Gibbs Entropy for an ensemble of parallel executions. The goal is …
