Improving Artistic Workflows For Fluid Simulation Through Adaptive And Editable Fluid Simulation Techniques, Sean A. Flynn Apr 2021

Improving Artistic Workflows For Fluid Simulation Through Adaptive And Editable Fluid Simulation Techniques, Sean A. Flynn

Theses and Dissertations

As the fidelity of computer generated imagery has increased, the need to digitally create convincing natural phenomena like fluids has become fundamental to the entertainment production industry. Because fluids are complex, the underlying physics must be computationally simulated. However, because a strictly physics-based approach is both computationally expensive and difficult to control, it does not lend itself well to the way artists and directors like to work. Directors require control to achieve their specific artistic vision. Furthermore, artistic workflows rely on quick iteration and the ability to apply changes late in the production process. In this dissertation we present novel …

Detection Of Gold Cysteine Thiolate Complexes On Gold Nanoparticles With Time-Of-Flight Secondary Ion Mass Spectrometry, Yolanda Hedberg, Jonas Hedberg, Valentin Romanovski, Elena Romanovskaia, Heng-Yong Nie Apr 2021

Detection Of Gold Cysteine Thiolate Complexes On Gold Nanoparticles With Time-Of-Flight Secondary Ion Mass Spectrometry, Yolanda Hedberg, Jonas Hedberg, Valentin Romanovski, Elena Romanovskaia, Heng-Yong Nie

Chemistry Publications

Gold (Au) nanoparticles (NPs) are widely used in nanomedical applications as a carrier for molecules designed for different functionalities. Previous findings suggested that biological molecules, including amino acids, could contribute to the dissolution of Au NPs in physiological environments and that this phenomenon was size-dependent. We, therefore, investigated the interactions of L-cysteine with 5-nm Au NPs by means of time-of-flight secondary ion mass spectrometry (ToF-SIMS). This was achieved by loading Au NPs on a clean aluminum (Al) foil and immersing it in an aqueous solution containing L-cysteine. Upon rinsing off the excessive cysteine molecules, ToF-SIMS confirmed the formation of gold …

Polymer Particles For The Intra-Articular Delivery Of Drugs To Treat Osteoarthritis, Xueli Mei, Ian J. Villamagna, Tony Nguyen, Frank Beier, C. Thomas Appleton, Elizabeth R. Gillies Apr 2021

Polymer Particles For The Intra-Articular Delivery Of Drugs To Treat Osteoarthritis, Xueli Mei, Ian J. Villamagna, Tony Nguyen, Frank Beier, C. Thomas Appleton, Elizabeth R. Gillies

Chemistry Publications

Osteoarthritis (OA) is a leading cause of chronic disability. It is a progressive disease, involving pathological changes to the entire joint, resulting in joint pain, stiffness, swelling, and loss of mobility. There is currently no disease-modifying pharmaceutical treatment for OA, and the treatments that do exist suffer from significant side effects. An increasing understanding of the molecular pathways involved in OA is leading to many potential drug targets. However, both current and new therapies can benefit from a targeted approach that delivers drugs selectively to joints at therapeutic concentrations, while limiting systemic exposure to the drugs. Delivery systems including hydrogels, …

Removal Of Carbamazepine Onto Modified Zeolitic Tuff In Different Water Matrices: Batch And Continuous Flow Experiments, Othman A. Al-Mashaqbeh, Daniel D. Snow, Diya A. Alsafadi, Layal Z. Alsalhi, Shannon L. Bartelt-Hunt

School of Natural Resources: Faculty Publications

Carbamazepine (CBZ) is the most frequently detected pharmaceutical residues in aquatic environments effluent by wastewater treatment plants. Batch and column experiments were con-ducted to evaluate the removal of CBZ from ultra-pure water and wastewater treatment plant (WWTP) effluent using raw zeolitic tuff (RZT) and surfactant modified zeolite (SMZ). Point zero net charge (pHpzc), X-ray diffraction (XRD), X-ray fluorescence (XRF), and Fourier Transform Infrared (FTIR) were investigated for adsorbents to evaluate the physiochemical changes resulted from the modification process using Hexadecyltrimethylammonium bromide (HDTMA-Br). XRD and FTIR showed that the surfactant modification of RZT has created an amorphous surface with new alkyl …

Multilattice Tilings And Coverings, Joshua Randall Linnell Apr 2021

Multilattice Tilings And Coverings, Joshua Randall Linnell

Theses and Dissertations

Let L be a discrete subgroup of \mathbb{R}^n under addition. Let D be a finite set of points including the origin. These two sets will define a multilattice of \mathbb{R}^n. We explore how to generate a periodic covering of the space \mathbb{R}^n based on L and $D$. Additionally, we explore the problem of covering when we restrict ourselves to covering \mathbb{R}^n using only dilations of the right regular simplex in our covering. We show that using a set D= {0,d} to define our multilattice the minimum covering density is 5-\sqrt{13}. Furthermore, we show that when we allow for an arbitrary …

Networking Frameworks: A Method For Analyzing The Complexities Of Classroom Cultures Focusing On Justifying, Eva Thanheiser, Kathleen Melhuish, Amanda Sugimoto, Brenda Rosencrans, Ruth Heaton Apr 2021

Networking Frameworks: A Method For Analyzing The Complexities Of Classroom Cultures Focusing On Justifying, Eva Thanheiser, Kathleen Melhuish, Amanda Sugimoto, Brenda Rosencrans, Ruth Heaton

Mathematics and Statistics Faculty Publications and Presentations

In this paper, we network five frameworks (cognitive demand, lesson cohesion, cognitive engagement, collective argumentation, and student contribution) for an analytic approach that allows us to present a more holistic picture of classrooms which engage students in justifying. We network these frameworks around the edges of the instructional triangle as a means to coordinate them to illustrate the observable relationships among teacher, students(s), and content. We illustrate the potential of integrating these frameworks via analysis of two lessons that, while sharing surface level similarities, are profoundly different when considering the complexities of a classroom focused on justifying. We found that …

Investigating The Hydrology Of The Western Greenland Ice Sheet: Spatiotemporal Variability And Implications On Ice-Dynamics, Jessica Z. Mejia Apr 2021

Investigating The Hydrology Of The Western Greenland Ice Sheet: Spatiotemporal Variability And Implications On Ice-Dynamics, Jessica Z. Mejia

USF Tampa Graduate Theses and Dissertations

Since the 1990's the Greenland Ice Sheet (GrIS) has been losing mass at an accelerating rate in response to climatic warming and is currently the largest terrestrial contributor to sea-level rise. While ice sheet models agree the GrIS will continue losing mass throughout the century, there are significant uncertainties associated with future sea-level rise contributions. Predicting the GrIS's response to future climate warming scenarios is limited by gaps in our understanding of the links between ice sheet hydrology and dynamics. Meltwater produced on the ice surface flows within supraglacial streams that deliver it to crevasses or moulins—vertical conduits extending from …

Listening To Women: Using A Mixed-Methods Approach To Understanding Women’S Desires And Experience During Childbirth, Nicole Loraine Falk Smith Apr 2021

Listening To Women: Using A Mixed-Methods Approach To Understanding Women’S Desires And Experience During Childbirth, Nicole Loraine Falk Smith

USF Tampa Graduate Theses and Dissertations

This dissertation is based on evolutionary medicine and applied anthropological research where the narratives and biology of modern women are used to inform evolutionary theory, specifically obligate midwifery, and modern birth practices. Improvements to the US maternity care systems are needed as rates of maternal mortality and morbidity are continually higher than rates in other technologically advanced nations. Additionally, women birthing under the technocratic model of care, as is predominant in the US, report trauma and post-traumatic stress disorders due to their birthing experience, and more women are experiencing postpartum depression. Thus, I seek to use an evolutionary medicine perspective …

The Dns Bake Sale: Advertising Dns Cookie Support For Ddos Protection, Jacob Davis Apr 2021

The Dns Bake Sale: Advertising Dns Cookie Support For Ddos Protection, Jacob Davis

Theses and Dissertations

The Domain Name System (DNS) has been frequently abused for Distributed Denial of Service (DDoS) attacks and cache poisoning because it relies on the User Datagram Protocol (UDP). Since UDP is connection-less, it is trivial for an attacker to spoof the source of a DNS query or response. DNS Cookies, a protocol standardized in 2016, add pseudo-random values to DNS packets to provide identity management and prevent spoofing attacks. This work finds that 30% of popular authoritative servers and open recursive resolvers fully support cookies and that 10% of recursive clients send cookies. Despite this, DNS cookie use is rarely …

A Dft Study Of The Adsorption Of Deep Eutectic Solvents Onto Graphene And Defective Graphene Nanoflakes, Mehdi Shakourian-Fard, S. Maryamdokht Taimoory, Hamid Reza Ghenaatian, Ganesh Kamath, John F. Trant Apr 2021

A Dft Study Of The Adsorption Of Deep Eutectic Solvents Onto Graphene And Defective Graphene Nanoflakes, Mehdi Shakourian-Fard, S. Maryamdokht Taimoory, Hamid Reza Ghenaatian, Ganesh Kamath, John F. Trant

Chemistry and Biochemistry Publications

The interaction of four deep choline chloride-derived eutectic solvents (DESs) with both graphene nanoflakes (GNF) and its defective double-vacancy and Stone–Wales forms (DV-GNF and SW-GNF), was evaluated using density functional theory (DFT). The presence of defects increases the adsorption energy of DESs, following the order DES∩DV-GNF > DES∩SW-GNF > DES∩GNF. Non-covalent interaction and energy decomposition analyses show that the interactions are noncovalent and dominated by dispersive forces. Furthermore, we find that the presence of aromatic moieties in the DESs increases the van der Waals interactions with the surfaces. These interactions decrease the HOMO-LUMO (Eg) energy gap of the surfaces and thus increase …

Carbon Dots For Specific “Off-On” Sensing Of Co2+ And Edta For In Vivo Bioimaging, Xiangping Wen, Guangming Wen, Wenyan Li, Zhonghua Zhao, Xine Duan, Wenjun Yan, John F. Trant, Yingqi Li

Chemistry and Biochemistry Publications

Fluorescent carbon dots (CDs) were hydrothermally synthesized from a mixture of frozen tofu, ethylenediamine and phosphoric acid in an efficient 64% yield. The resulting CDs exhibit good water solubility, low cytotoxicity, high stability, and excellent biocompatibility. The CDs selectively and sensitively detect Co2+ through fluorescent quenching with a detection limit of 58 nM. Fluorescence can be restored through the introduction of EDTA, and this phenomenon can be used to quantify EDTA in solution with a detection limit of 98 nM. As both analytes are detected by the same CD platform, this is an “off-on” fluorescence sensor for Co2+ and EDTA. …
