Understanding Synesthesia And Impact For Learning, Kateri Lynn Wheeler

Dissertations, Masters Theses, Capstones, and Culminating Projects

Synesthesia is a neurological disorder that has to do with the ‘union of the senses.’ The literature reveals that students with synesthesia are affected with various degrees of severity. Students may hear a bell ring. Their brain is wired to take that sound and interpret it differently, through color, texture, taste, sound or temperature among other things. While some people hear a bell, others may also experience the activation of another sense. The difficulties these students exhibit involves longer processing or thinking time to sort out the extra stimulus. Limiting sound environments and other visual cues like color coding to …

Surface Shape Perception In Volumetric Stereo Displays, Meng Zhu

All Dissertations

In complex volume visualization applications, understanding the displayed objects and their spatial relationships is challenging for several reasons. One of the most important obstacles is that these objects can be translucent and can overlap spatially, making it difficult to understand their spatial structures. However, in many applications, for example medical visualization, it is crucial to have an accurate understanding of the spatial relationships among objects. The addition of visual cues has the potential to help human perception in these visualization tasks. Descriptive line elements, in particular, have been found to be effective in conveying shape information in surface-based graphics as …

Predictive Maturity Of Inexact And Uncertain Strongly Coupled Numerical Models, Ismail Farajpour

All Dissertations

The Computer simulations are commonly used to predict the response of complex systems in many branches of engineering and science. These computer simulations involve the theoretical foundation, numerical modeling and supporting experimental data, all of which contain their associated errors. Furthermore, real-world problems are generally complex in nature, in which each phenomenon is described by the respective constituent models representing different physics and/or scales. The interactions between such constituents are typically complex in nature, such that the outputs of a particular constituent may be the inputs for one or more constituents. Thus, the natural question then arises concerning the validity …

Can Clustering Improve Requirements Traceability? A Tracelab-Enabled Study, Brett Taylor Armstrong

Master's Theses

Software permeates every aspect of our modern lives. In many applications, such in the software for airplane flight controls, or nuclear power control systems software failures can have catastrophic consequences. As we place so much trust in software, how can we know if it is trustworthy? Through software assurance, we can attempt to quantify just that.

Building complex, high assurance software is no simple task. The difficult information landscape of a software engineering project can make verification and validation, the process by which the assurance of a software is assessed, very difficult. In order to manage the inevitable information overload …

Contract As Pattern Language, Erik F. Gerding

Washington Law Review

This essay examines how patterns enable the transformation of contractual provisions into contracts, contracts into transactions, and transactions into markets. Although contract design patterns are broader than contract boilerplate (as described in Part II.C. below), some of the extensive legal scholarship on boilerplate19 helps explain how contract patterns generate agreements, transactions, and markets. The work of Henry Smith on the modularity of contract boilerplate proves particularly useful in this regard. Contract patterns perform several functions. Contract patterns break complex problems and bargains into components. Attorneys can then repeatedly apply these particular solutions to similar problems. Patterns also serve as heuristics …

Putting The Ghost Back In The Machine: A Defense Of Common Sense Dualism, Matthew Andrew Skene

Dissertations - ALL

Gilbert Ryle once ridiculed substance dualism, describing it as the view that we are a "ghost in the machine." Since that time, substance dualism has found few defenders, and a presumption toward naturalism has dominated philosophical inquiry. Here, I offer an unapologetic defense this unfashionable view of the self. To do so, I first explain why philosophy should endorse a shift in method away from naturalism and toward common sense philosophy. I then show how, from within that approach, substance dualism is far better supported than its competitors. My defense of the common sense method rests heavily on an account …

Pedagogical Promise, Disciplinary Practice, And The Fashioning Of Identities Among Marshallese Youth In Primary School, Laurence Marshall Carucci

Pacific Studies

This paper examines the educational experiences of elementary grade students from the Ujelang/Enewetak community across two distinct periods and locations: those residing on Ujelang Atoll in the 1970s and those living in Hawai‘i in 2002–2003. These children belong to a community that has endured profound historical trauma and rapid social transformation, while maintaining a strong commitment to preserving its cultural and historical identity. The study situates the community within the broader context of colonial and postcolonial displacement, highlighting the devastating impact of World War II and U.S. nuclear testing on Enewetak. It explores how these historical events have shaped migration …

Findings from this study support the viability and benefits of applying blended learning in teacher education at the program level. On the other hand, …

Cultural Adaptations Of American Teachers In International Schools, David J. Alban

Dissertations

Global competition of academic aptitude between countries has sparked policymakers’ concerns with the performance of the United States educational system leading to many educational reforms that direct educators to diversify their instruction to meet the needs of all students. Advances in technology and travel allow people to interact with other cultures creating more globalized societies. These two converging issues place a greater significance on educators to understand the interplay between culture and their teaching practices.

Literature reveals that the influence of home and community cultures affects the learning behaviors of students (Davis-Kean, 2005: Wang, Beras, & Eberhard, 2005; Sigel, Stinson, …

Fuzzy Search Strategy Generation For Adversarial Systems Using Fuzzy Process Particle Swarm Optimization, Fuzzy Patterns, And A Hunch Factor, Stephany Coffman-Wolph

Dissertations

Adversarial game-playing situations have been studied in both game theory and artificial intelligence since the 1950s. However, developing strategies for game playing is challenging due to the large search tree size as the environment size increases. The research presented develops a centralized fuzzy search strategy to find winning strategies for adversarial situations using fuzzy logic. The aforementioned fuzzy algorithm, Fuzzy Strategy Finder (FSF), can be used to find valid strategies for any problem that can be written as a Reti-like or zero-sum game. Using several chess endgames, the FSF will be shown to have a faster runtime without a significant …

Development Of Polarization Analysis Of Resonant Inelastic X-Ray Scattering, Xuan Gao

Dissertations

Resonant inelastic x-ray scattering (RIXS) is a powerful technique in condensed matter physics for studying the electronic excitations in novel materials of interest. In currently operating hard x-ray RIXS instruments the energy and momentum transfers are measured while the outgoing polarization is not measured due to significant technical challenges. But the outgoing polarization of the scattered photons provides valuable information (excitation symmetry) about the states involved in the scattering which is difficult to determine without polarization analysis. Polarization analysis has proved extremely valuable in soft x-ray RIXS, and so a polarization analysis system is being developed to fill the technical …

Quantifying Value In Public Health: Using Economic Methods To Analyze System Change, Theresa M. Green

Dissertations

In this time of economic downturn, it is becoming increasingly important for organizations, including those in public health, to “prove their worth,” to show the value in improvement strategies. Health agencies have learned to discuss impact in terms of health outcome and mortality/morbidity measures. However, it is critical that these impacts are also expressed in a way that shows cost-efficiency and economic benefit especially for promising, evidence-based public health interventions. Although several methods of economic evaluation including cost-effective analysis, cost-utility analysis, or cost-benefit analysis and return on investment (ROI) have been used in social sciences and health research, fewer examples …

Client-Based Qos Monitoring And Evaluation Architecture For Network Infrastructure And Services, Ammar Mohammed Kamel

Dissertations

Providing an efficient Quality-of-Service (QoS) measurement model is a challenging problem in today’s mobile computing and telecommunications networks. Currently, most of QoS techniques utilize service measurements that are collected by the network elements (i.e., network-side monitoring) to evaluate the network performance. However, this process does not take into account the service performance from the clients' perspective and might contradict with the Service Level Agreement (SLA). In order to overcome the limitations of service-side QoS monitoring, a number of research studies have been conducted to present alternative architectures and algorithms for client-side QoS service assessment in computer networks. The client-side QoS …

Utilizing Persistent Scatterer Interferometry To Investigate The Nature And Factors Controlling Nile Delta Subsidence, El Hachemi Yousef Bouali

Masters Theses

The Nile Delta in Egypt is being threatened by two continuous and relatively slow hazards: encroachment from the Mediterranean Sea as sea levels rise and land subsidence of the delta itself. The magnitude of sea level rise has been actively monitored, while the subsidence of the Nile Delta has not been adequately quantified spatially and temporally. Instead, all previous studies have either focused on measuring average Holocene subsidence rates or modern subsidence rates on local scales (point- or city-scale).

The overall study objective is three-fold: (1) to measure and map the spatial variations in subsidence rates across the entire Nile …

Application Of Fractional Moments For Comparing Random Variables With Varying Probability Distributions, Munther R. Al Shami, A. R. Mugdadi, R. R. Nigmatullin, S. I. Osokin

Applications and Applied Mathematics: An International Journal (AAM)

New methods are being presented for statistical treatment of different random variables with unknown probability distributions. These include analysis based on the probability circles, probability ellipses, generalized mean values, generalized Pearson correlation coefficient and the beta-function analysis. Unlike other conventional statistical procedures, the main distinctive feature of these new methods is that no assumptions are made about the nature of the probability distribution of the random series being evaluated. Furthermore, the suggested procedures do not introduce uncontrollable errors during their application. The effectiveness of these methods is demonstrated on simulated data with extended and reduced sample sizes having different probability …

The Importance Of Mapping To The Next Generation Retinal Prosthesis, Jonathan Gesell

Student Work

Evolutionarily, human beings have come to rely on vision more than any other sense, and with the prevalence of visual-oriented stimuli and the necessity of computers and visual media in everyday activities, this can be problematic. Therefore, the development of an accurate and fast retinal prosthesis to restore the lost portions of the visual field for those with specific types of vision loss is vital, but current methodologies are extremely limited in scope. All current models use a spatio-temporal filter (ST), which uses a difference of Gaussian (DOG) to mimic the inner layers of the retina and a noisy leak …

Collaboration Between Grant-Making Organizations, Evaluators, And Program Staff Related To Standardized Evaluation Requirements, Kristin M. Everett

Dissertations

Nonprofit organizations have received funding from grant-making organizations and foundations for many years. These funds have been used to support programs developed by the nonprofit organization. Over the years, two critical developments have occurred between grant-making organizations and nonprofit organizations related to evaluation and collaboration. First, grant-making organizations and nonprofit organizations are combining funds and resources to collaborate on projects. Second, program evaluation has become an essential piece of many grant-funded projects.

Historically, nonprofit organizations receiving funding from multiple sources were required to implement multiple monitoring and evaluation plans and write a report for each funder. These reports use staff …

Viscosity Dependence Of Faraday Wave Formation Thresholds, Lisa Michelle Slaughter

Physics

This experiment uses an electromagnetic shaker to produce standing wave patterns on the surface of a vertically oscillating sample of silicon liquid. These surface waves, known as Faraday waves, form shapes such as squares, lines, and hexagons. They are known to be dependent upon the frequency and amplitude of the forcing as well as on the viscosity and depth of the liquid in the dish. At a depth of 4mm and for various silicon liquids having kinematic viscosities of 10, 20, and 38 cSt, we determined the acceleration at which patterns form for frequencies between 10 and 60 Hz. For …

Designing A Robust Production System For Erratic Demand Environments., Joseph Elias El-Khoury 1963-

Electronic Theses and Dissertations

Production systems must have the right type of material in the right quantities when required for production. They must minimize the work in progress while ensuring no stock-outstock-out occurs. While these twin opposing goals are achievable when demand is stable, they are difficult to realize under an erratic demand pattern. This dissertation aims to develop a production system that can meet erratic demands with minimal costs or errors. After a detailed introduction to the problem considered, we review the relevant literature. We then conduct a numerical analysis of current production systems, identify their deficiencies, and then present our solution to …

Gravitational And Electromagnetic Waves On The Null Cone, Maria Babiuc-Hamilton

Physics Faculty Research

Gravitational radiation is properly defined only at future null infinity, but mathematically it is estimated at a finite radius, and then extrapolated. Our group developed a characteristic waveform extraction tool, implemented in an open source code, which computes the gravitational waves infinitely far from their source, in terms of compactified null cones, by numerically solving Einstein equation. We add electromagnetic waves to the null cone, by deriving a formulation of the Einstein-Maxwell equations suitable to be numerically implemented into a characteristic code, that will evolve and calculate both the gravitational waves and their electromagnetic counterparts all the way to infinity.

Kinematic Synthesis Of Planar, Shape-Changing, Rigid Body Mechanisms For Design Profiles With Significant Differences In Arc Length, Shamsul A. Shamsudin, Andrew P. Murray, David H. Myszka, James P. Schmiedeler

Mechanical and Aerospace Engineering Faculty Publications

This paper presents a kinematic procedure to synthesize planar mechanisms capable of approximating a shape change defined by a general set of curves. These “morphing curves,” referred to as design profiles, differ from each other by a combination of displacement in the plane, shape variation, and notable differences in arc length. Where previous rigid-body shape-change work focused on mechanisms composed of rigid links and revolute joints to approximate curves of roughly equal arc length, this work introduces prismatic joints into the mechanisms in order to produce the different desired arc lengths. A method is presented to iteratively search along the …

The Role Of Youth Program Leaders In The Use Of Technology: Challenges And Opportunities For Youth-Serving Organizations, Mimi Nichter, Lynne Borden, Veronica Przybyl

Journal of Youth Development

Youth-serving organizations offer young people an opportunity to gain skills and advance their knowledge of current and evolving technology through experiential learning. The key to ensuring that young people have meaningful learning experiences is directly related to the youth program leader who is responsible for designing and implementing these programs. Programs conducted by well-trained and well-prepared adults are an essential component of community-based interventions. To date, there is relatively limited research on how technology such as smart phones can be used in community-based programs and the success or failure of this as a strategy for delivering information and engaging young …

Several New Families Of Jarratt’S Method For Solving Systems Of Nonlinear Equations, V. Kanwar, Sanjeev Kumar, Ramandeep Behl

Applications and Applied Mathematics: An International Journal (AAM)

In this study, we suggest and analyze a new and wide general class of Jarratt’s method for solving systems of nonlinear equations. These methods have fourth-order convergence and do not require the evaluation of any second or higher-order Fréchet derivatives. In terms of computational cost, all these methods require evaluations of one function and two first-order Fréchet derivatives. The performance of proposed methods is compared with their closest competitors in a series of numerical experiments. It is worth mentioning that all the methods considered here are found to be effective and comparable to the robust methods available in the literature.

A Note On The Qualitative Behavior Of Some Second Order Nonlinear Equation, Juan E. Nápoles Valdes

Applications and Applied Mathematics: An International Journal (AAM)

In this paper, we present two qualitative results concerning the solutions of some second order nonlinear equations, under suitable assumptions. The first result centers on the boundedness of the solutions while the second discusses the square integrability of the solutions. These results are obtained by extending and improving the current literature through sound mathematical analysis.
