Optimal Relaxation Weights For Multigrid Reduction In Time (Mgrit), Masumi Sugiyama

Mathematics & Statistics ETDs

Based on current trends in computer architectures, faster compute speeds must come from increased parallelism rather than increased clock speeds, which are stagnate. This situation has created the well-known bottleneck for sequential time-integration, where each individual time-value (i.e., time-step) is computed sequentially. One approach to alleviate this and achieve parallelism in time is with multigrid. In this work, we consider the scheme known as multigrid-reduction-in-time (MGRIT), but note that there exist other parallel-in-time methods such as parareal and the parallel full approximation scheme in space and time (PFASST). MGRIT is a full multi-level method applied to the time dimension and …

Managing Overheads In Asynchronous Many-Task Runtime Systems, Bibek Wagle

LSU Doctoral Dissertations

Asynchronous Many-Task (AMT) runtime systems are based on the idea of dividing an algorithm into small units of work, known as tasks. The runtime system is then responsible for scheduling and executing these tasks in an efficient manner by taking into account the resources provided to it and the associated data dependencies between the tasks. One of the primary challenges faced by AMTs is managing such fine-grained parallelism and the overheads associated with creating, scheduling and executing tasks. This work develops methodologies for assessing and managing overheads associated with fine-grained task execution in HPX, our exemplar Asynchronous Many-Task runtime system. …

Cfd Analysis Of Bridge Pier Geometry On Local Scour Potential, Erin M. Dougherty

LSU Master's Theses

Scour at bridge piers is one of the highest contributing failure factors of bridges. One way to minimize local scour is to alter the flow around a bridge pier and thereby reduce the strength of the downflow and horseshoe vortices. There are many flow-altering scour countermeasures including altering the geometry of the pier itself or by adding a plate or sheath to the base of the pier. Computational Fluid Dynamics (CFD) is a useful method to model and analyze the effects of pier configuration on flow velocity distribution profiles and bed shear stress. The hydrodynamic component of local scour at …

The University of Iowa’s Robot Theater Project teaches computational thinking and promotes STEM education in the context of the performing arts. Students write scripts and program robots to give live performances on stage; over the past 5 years we have taught 122 students to program robots, and our robots have performed in front of several thousand students, teachers, and parents. In this experience report, we introduce the project, describe the framework used to coordinate the behavior of multiple robots in a scene, and discuss the challenges with live performances involving robot actors from different manufacturers. We also describe an initiative …

International Competition As Stopgap Curriculum: Case Study Of Ryerson Invitational Thrill Design Competition, Kathryn Woodcock

Symposium on Education in Entertainment and Engineering

Students aspiring to careers in the themed entertainment and attractions industry have few formal options to learn and demonstrate skills and knowledge specific to the industry. Students have shown initiative in developing extracurricular activities, and industry has reached out to offer “next generation” programs and internships. It still remains problematic for industry employers to select the best qualified students from a large pool of aspirants and for motivated candidates to stand out as highly qualified for these opportunities. The Ryerson Invitational Thrill Design Competition (RITDC) was developed to address this problem. RITDC provides learning experiences and performance evaluation with not …

The Benefits Of Music Education In Urban Education, Emily E. Mattulke

The International Undergraduate Journal For Service-Learning, Leadership, and Social Change

In an attempt to show the benefits of music education in urban education, a student observer’s own accounts are analyzed alongside empirical data. The studies of Adrian Hille, Jürgen Schupp, and Peter Miksza are paired with her own anecdotes to create a full picture of music’s effect on a child’s education, especially those from lower income environments. Conclusively, it is found that urban education thrives in the presence of music education, and that the slow stripping away of music programs in American education is detrimental to these benefits, especially for those in impoverished areas where the benefits can be extremely …

Mapping Crustal Shear Wave Velocity Structure And Radial Anisotropy Beneath West Antarctica Using Seismic Ambient Noise, J. P. O'Donnell, Audrey D. Huerta, J. Paul Winberry

All Faculty Scholarship for the College of the Sciences

Using 8- to 25-s-period Rayleigh and Love wave phase velocity dispersion data extracted from seismic ambient noise, we (i) model the 3-D shear wave velocity structure of the West Antarctic crust and (ii) map variations in crustal radial anisotropy. Enhanced regional resolution is offered by the UK Antarctic Seismic Network. In the West Antarctic Rift System (WARS), a ridge of crust ∼26–30km thick extending south from Marie Byrd Land separates domains of more extended crust (∼22km thick) in the Ross and Amundsen Sea Embayments, suggesting along-strike variability in the Cenozoic evolution of the WARS. The southern margin of the WARS …

A Class Of N-Player Colonel Blotto Games With Multidimensional Private Information, Christian Ewerhart, Dan Kovenock

ESI Working Papers

We consider a class of incomplete-information Colonel Blotto games in which N ≥ 2 agents are engaged in (N + 1) battlefields. An agent’s vector of battlefield valuations is drawn from a generalized sphere in L_p-space. We identify a Bayes-Nash equilibrium in which any agent’s resource allocation to a given battlefield is strictly monotone in the agent’s valuation of that battlefield. In contrast to the single-unit case, however, agents never enjoy any information rent. We also outline an extension to networks of Blotto games.

Bis(Tetra­Phenyl­Arsonium) Hexa­Fluorido­Technetate(Iv) Dihydrate: Preparation, Structure And Spectroscopic Analysis, Samundeeswari Mariappan Balasekaran, Frederic Poineau

Chemistry and Biochemistry Faculty Research

Reports of quadrivalent transition-metal fluoride salts containing bulky organic cations are limited. In this context, we prepared the bis­(tetra­phenyl­arsonium) hexa­fluorido­technetate(IV) dihydrate salt, (C24H20As)2[TcF6]·2H2O, by a cation metathesis reaction of (NH4)2[TcF6] in water. This is the first report of an arsonium salt of the hexa­fluorido­technetate(IV) dianion. (AsPh4)2[TcF6]·2H2O crystallizes in the triclinic space group P[\overline{1}]. The [TcF6]2− anion adopts a slightly distorted octa­hedral geometry with an average Tc—F bond length of 1.933 Å. The cyclic voltammogram of (AsPh4)2[TcF6]·2H2O in CH3CN shows a one-electron reversible oxidation wave at 1.496 V.

Teachers And Administrators Explain How And Why Teachers Change Instructional Methods In A Pre-K Through Eight Catholic School, Judith A. Deeley

USF Tampa Graduate Theses and Dissertations

This qualitative exploratory study explored how and why teachers at four small Catholic schools in the state of Florida transformed by changing instructional methods to offer full integration of science, technology, religion, engineering, arts and mathematics (STREAM) approaches into learning experiences for grades pre-k through eight. There was a time up until the early 2000s that Catholic school enrollment was at capacity and did not require differentiation based upon unique student learning needs. However, students of current times reflect a higher need for educational approaches that are both differentiated and engaging.

Exploring Teacher Candidates' Facilitation Of Common Core Mathematical Practice Three, Andrea Scalzo Willson

USF Tampa Graduate Theses and Dissertations

The Common Core State Standards in Mathematics (CCSSM, 2010), refer to eight distinct Mathematical Practices describing what students should be doing for optimal learning during mathematics lessons. Specifically, Mathematical Practice 3 (MP3), “construct viable arguments and critique the reasoning of others” (CCSSM, 2010, para 4), posits students who are proficient in mathematics are able to compare different solutions, distinguish correct and logically sound answers from those that are incorrect and then explain why the solution is incorrect (CCSSM, 2010). MP3 requires teachers to provide opportunities for students to engage in discussions beyond just “show and tell” talk to develop a …

Dynamic Prediction Of Runway Configuration And Airport Acceptance Rate, Yuan Wang

USF Tampa Graduate Theses and Dissertations

Automated prediction of runway configuration and airport capacity is critical for the future generation of air traffic management. In the future aviation industry, multi-sources weather forecast information will be available for air traffic decision-making units; how to use these data efficiently is key for overall efficiency of air traffic management. Currently, air traffic management personnel lack tools to assist them to translate weather forecast data into real-time airport capacity. Runway configurations and AARs of airports in a multi-airport system are determined by different air traffic controller personnel. The lack of synchronization may lead to the loss of efficiency of the …

© Copyright © 2019 Shah, Li, Kury, Zeb, Khatoon, Liu, Yang, Liu, Yao, Khan, Koh, Jiang and Li. Ischemic strokes are categorized by permanent or transient obstruction of blood flow, which impedes delivery of oxygen and essential nutrients to brain. In the last decade, the therapeutic window for tPA has increased from 3 to 5–6 h, and a new technique, involving the mechanical removal of the clot (endovascular thrombectomy) to allow reperfusion of the injured area, is being used more often. This last therapeutic approach can be done until 24 h after stroke onset. Due to this fact, more acute …

The Use Of Social Media In Emergency Management By Public Agencies And Non-Governmental Organizations: Lessons Learned From Areas Affected By Hurricanes Isaac, Sandy, And Harvey, Ryan Hamilton Kirby

LSU Doctoral Dissertations

Natural disasters are increasingly costly for the United States. The literature suggests emergency managers may improve disaster outcomes and enhance disaster resilience by supplementing their official public-communications methods with more bi-directional communication tactics using social media. This study aims to understand how social media is used within the “whole community” of emergency management in areas affected by recent hurricanes. The first research objective examines how social media is used by governmental and non-governmental organizations across the four phases of emergency management (preparedness, response, recovery, mitigation). The second objective is to identify challenges governmental and non-governmental groups have encountered and strategies …

The Effects Of Temperature On The Yields Of Aliphatic And Aromatic Products From The Supercritical Pyrolysis Of 1-Octene, Elizabeth Anne Hurst

LSU Doctoral Dissertations

Prior to their combustion, fuels for future high-speed aircraft are expected to experience supercritical conditions, leading to the production of polycyclic aromatic hydrocarbons (PAH), precursors to solid carbonaceous deposits, via pyrolytic reactions. These solid deposits can clog fuel-transfer lines, causing unsafe aircraft operation. To prevent the formation of fuel-line deposits, it is critical to understand the reaction pathways that lead to PAH formation in the supercritical fuel pyrolysis environment.

To better understand the role of large 1-alkenes in PAH formation, supercritical pyrolysis experiments with model fuel 1-octene, a representative 1-alkene product from supercritical n-alkane pyrolysis, have been performed. The …

Validation Of Gaseous Absorption & Cloud Attenuation Models Utilizing A 72 Ghz Terrestrial Link, Ralph Lyndon Gesner

Electrical and Computer Engineering ETDs

Interest in the W & V-bands of the radio frequency (RF) spectrum has become steadily more desirable for system designers due to the ever increasing need for greater communication bandwidths and higher data rates. The 40 GHZ to 110 GHz range that constitutes the W & V-bands provide a unique solution to both of these current demands by providing a bandwidth nearly double that of all current RF frequencies in use. To date, this range has only been used for point to point satellite and short link communications meaning these bands have remained largely unexplored and undeveloped.

Biomimetic Light Harvesting In Metalloporphyrins Encapsulated/Incorporated Within Metal Organic Frameworks (Mofs)., Abdulaziz A. Alanazi

USF Tampa Graduate Theses and Dissertations

The Global energy supply relies mostly on fossil fuels and only 10% comes from renewable energy. These places humankind in an unsafe situation as the fossil fuel resources won’t last forever. More efficient use of renewable energy is required sooner than later to meet the growing energy need. A promising approach is to utilize light harvesting chromophores (e.g., porphyrin derivatives) to advance organic photovoltaics and increase its efficiency or to improve photocatalysts. Metal-organic frameworks (MOFs) can be employed to aid the self-assembly of the porphyrin chromophores in a large light-harvesting system comparable to the natural photosystem. The advantage of using …

Introducing A Mobile Health Care Platform In An Underserved Rural Population: Reducing Assimilations Gaps On Adoption And Use Via Nudges, Joseph Hodges

USF Tampa Graduate Theses and Dissertations

Rural communities are often overlooked when it comes to offering cutting edge consumer healthcare technologies. Mobile applications usually exclude populations in rural demographics due to the infrastructure requirements and available technology in the region. The population studied is a low income rural health plan in southwest Georgia. They are uniquely considered as they have the highest healthcare costs in the U.S. and are compared to healthcare costs among higher income populations like Vail, Colorado. Innovations, such as mobile healthcare applications, have the capacity to offset some of these costs, but even if adoption occurs, this does not guarantee use will …
