Dynamic Modeling, Simulation And Control Design Of A Parafoil-Payload System For Ship Launched Aerial Delivery System (Slads), Anand S. Puranik

Dissertations, Master's Theses and Master's Reports - Open

The objective of this research was to develop a high-fidelity dynamic model of a parafoilpayload system with respect to its application for the Ship Launched Aerial Delivery System (SLADS). SLADS is a concept in which cargo can be transfered from ship to shore using a parafoil-payload system. It is accomplished in two phases: An initial towing phase when the glider follows the towing vessel in a passive lift mode and an autonomous gliding phase when the system is guided to the desired point. While many previous researchers have analyzed the parafoil-payload system when it is released from another airborne vehicle, …

Dynamic Modeling Of Active Regeneration In Catalyzed And Non-Catalyzed Diesel Particulate Filters, Aamod Pethe

Dissertations, Master's Theses and Master's Reports - Open

Particulate matter (PM) emissions standards set by the US Environmental Protection Agency (EPA) have become increasingly stringent over the years. The EPA regulation for PM in heavy duty diesel engines has been reduced to 0.01 g/bhp-hr for the year 2010. Heavy duty diesel engines make use of an aftertreatment filtration device, the Diesel Particulate Filter (DPF). DPFs are highly efficient in filtering PM (known as soot) and are an integral part of 2010 heavy duty diesel aftertreatment system.

PM is accumulated in the DPF as the exhaust gas flows through it. This PM needs to be removed by oxidation periodically …

Topological Changes In 2d Simplicial Meshes For The Simulation Of Fractures, James R. Thunes

Dissertations, Master's Theses and Master's Reports - Open

A method for the introduction of strong discontinuities into a mesh will be developed. This method, applicable to a number of eXtended Finite Element Methods (XFEM) with intra-element strong discontinuities will be demonstrated with one specific method: the Generalized Cohesive Element (GCE) method. The algorithm utilizes a subgraph mesh representation which may insert the GCE either adaptively during the course of the analysis or a priori. Using this subgraphing algorithm, the insertion time is O(n) to the number of insertions. Numerical examples are presented demonstrating the advantages of the subgraph insertion method.

Performance Characteristics And Design Recommendations For Biomass-Burning Stoves Using Earthen Construction Materials , Nicholas H. Schreiner

Dissertations, Master's Theses and Master's Reports - Open

This report provides an analysis of the thermal performance and emissions characteristics of improved biomass stoves constructed using earthen materials. Commonly referred to as mud stoves, this type of improved stove incorporates high clay content soil with an organic binder in the construction of its combustion chamber and body. When large quantities of the mud material are used to construct the stove body, the stove does not offer significant improvements in fuel economy or air quality relative to traditional open fire cooking. This is partly because a significant amount of heat is absorbed by the mass of the stove reducing …

Attempting To Improve Standardized Test Results Using Study Islands' Web-Based Mastery Program , Paul J. Dube'

Dissertations, Master's Theses and Master's Reports - Open

State standardized testing has always been a tool to measure a school’s performance and to help evaluate school curriculum. However, with the school of choice legislation in 1992, the MEAP test became a measuring stick to grade schools by and a major tool in attracting school of choice students. Now, declining enrollment and a state budget struggling to stay out of the red have made school of choice students more important than ever before. MEAP scores have become the deciding factor in some cases.

For the past five years, the Hancock Middle School staff has been working hard to improve …

Locating American Indian Sciences : A Report On The Development, Use, And Analysis Of A Survey Of Perceptions, John Eric Holmlund

Dissertations, Master's Theses and Master's Reports - Open

All students in the United States of America are required to take science. But what if there is not a science, but in fact a number of sciences? Could every culture, perhaps every different grouping of people, create its own science? This report describes a preliminary survey, the goal of which is to improve the teaching of science at American Indian Opportunities and Industrialization Center in Minneapolis, Minnesota by beginning to understand the differences between Western and American Indian sciences.

Enumeration Of Inequivalent Cycle Decompositions, William J. Laffin

Dissertations, Master's Theses and Master's Reports - Open

A k-cycle decomposition of order n is a partition of the edges of the complete graph on n vertices into k-cycles. In this report a backtracking algorithm is developed to count the number of inequivalent k-cycle decompositions of order n.

Parallel Algorithm For Solving Integer Linear Programs, David O. Torrey Jr.

Dissertations, Master's Theses and Master's Reports - Open

Linear programs, or LPs, are often used in optimization problems, such as improving manufacturing efficiency of maximizing the yield from limited resources. The most common method for solving LPs is the Simplex Method, which will yield a solution, if one exists, but over the real numbers. From a purely numerical standpoint, it will be an optimal solution, but quite often we desire an optimal integer solution. A linear program in which the variables are also constrained to be integers is called an integer linear program or ILP. It is the focus of this report to present a parallel algorithm for …

Development Of An Optimization Model For Biofuel Facility Size And Location And A Simulation Model For Design Of A Biofuel Supply Chain, Fengli Zhang

Dissertations, Master's Theses and Master's Reports - Open

To mitigate greenhouse gas (GHG) emissions and reduce U.S. dependence on imported oil, the United States (U.S.) is pursuing several options to create biofuels from renewable woody biomass (hereafter referred to as “biomass”). Because of the distributed nature of biomass feedstock, the cost and complexity of biomass recovery operations has significant challenges that hinder increased biomass utilization for energy production. To facilitate the exploration of a wide variety of conditions that promise profitable biomass utilization and tapping unused forest residues, it is proposed to develop biofuel supply chain models based on optimization and simulation approaches. The biofuel supply chain is …

Chorister Formation Preferences In A Women's Choir, Janna Montgomery

Electronic Theses and Dissertations

While conductors and audience members are not committed to a single formation, choristers have a clear preference: sectional or mixed. Why is this? Participants in this study included forty-six members of an auditioned women's choir from a large southern university who completed a survey after singing in sectional and mixed formation. These SSAA results maintain previous research findings by James Daugherty, Debra Atkinson, and Christopher Aspaas, et al. from female choristers in SATB settings: most women prefer mixed formation. All 46 of the participants (100%) perceived that formation generally affects the choral sound, so they think formation is important. Women's …

Changing Teacher Candidates’ Perceptions Of Literacy In Content Classes: The Role Of Expert-Novice Dialogues, Peter Thacker, Sally Hood

Northwest Journal of Teacher Education

This manuscript details an exploratory study of an assignment in a literacy across the curriculum course that assisted teacher candidates to recognize the distance between expert and novice readers in their content specific teaching. The study explores how teacher candidates discovered strategies necessary to build comprehension of disciplinebased texts, particularly for novice readers. Data collection included multiple entries from thirty teacher candidate journals that were generated during partnered dialogues. Journals were analyzed for clues as to how teachers can better approach helping students to read varied disciplines’ texts with greater comprehension. Findings suggest that by placing teacher candidates in the …

Exploring Teacher Candidates’ Motivations To Teach, Maureen Siera, Steve Siera

Northwest Journal of Teacher Education

This qualitative study explored teacher candidates’ motivations to become teachers. As part of the application process, students are required to complete an onsite essay about why they want to become a teacher. The authors examined application essays of 53 candidates to identify motivations for becoming a teacher. From the data, we identified tentative categories and themes that explained students’ motivations for pursuing a program in teacher education. Upon refinement, these categories seem to group into three, not always mutually exclusive, themes: Altruism (Developing the student and Making a difference), Personal Fulfillment (Making a difference, Sharing knowledge and experience, Dispositional motivators, …

Six Japanese Gardens And Trois Rivières: Delta: An Analysis Of Kaija Saariaho’S Two Major Works For Solo Percussion And Electronics, Bradley Edward Meyer

Theses and Dissertations--Music

Music for solo multiple-percussion (“multi-percussion”) has been rapidly developing in terms of quantity of and creativity exhibited within works since this genre was established in the late 1950s. It is important to underscore, analyze, and question the music of composers who have helped further multi-percussion towards the highest level of musical excellence possible as the genre continues to expand and mature. Finnish-born composer Kaija Saairaho has achieved international fame and success with her acoustic, electronic, and electro-acoustic (the simultaneous combination of electronic and acoustic elements) compositions. She has a large body of musical works, including two compositions for solo percussionist …

From Programmatic Reform To Social Science Research: The National Tax Association And The Promise And Perils Of Disciplinary Encounters, Ajay K. Mehrotra, Joseph J. Thorndike

Articles by Maurer Faculty

This article uses the history of the National Tax Association (NTA), the leading twentieth-century organization of tax professionals, to strengthen our empirical understanding of the disciplinary encounter between law and the social sciences. Building on existing sociolegal scholarship, this article explores how the NTA embodied tax law's ambivalent historical interaction with public economics. Since its founding in 1907, the NTA has changed dramatically from an eclectic and catholic organization of tax professionals with a high public profile to an insular, scholarly association of mainly academic public finance economists. Using a mix of quantitative and qualitative historical evidence, we contend that …

Enhancing The Learning Experience: Learning For The Unknown Future, Barry Ryan

Conference papers

In this presentation the effects of an altered teaching methodology, in which the "student as producer" approach was adopted, are outlined. Currently, many students exist as knowledge consumers; however, Neary and Winn (2009) have suggested the positive effect on students learning through the inclusion of research-like activities at the core of the undergraduate curriculum; the students act as "producers" of knowledge.

New Mexico’S Major Reservoirs: An Overview, Susan Kelly, Diego Urbina

Water Matters!

This paper describes the salient facts about the major water storage reservoirs in New Mexico. For each reservoir, we address the purposes of water storage allowed by law, storage capacity, the responsible operating agency, and some key operational issues. This is by necessity a vast simplification of the topic.Books, articles, research reports, operation manuals, and other materials on these topics run into the hundreds. Millions of dollars have been spent on technical studies and computer models to understand,and sometimes alter, the operations of various dams and reservoirs.

Neutrosophic Interpretation Of The Analects Of Confucius, Florentin Smarandache, Fu Yuhua

Branch Mathematics and Statistics Faculty and Staff Publications

This book is the companion volume of "Neutrosophic Interpretation of Tao Te Ching,” its purpose is to extend the foundation and application range of “The Analects of Confucius.” The reasons for this are as follows. Firstly, we are willing to point out that The Analects of Confucius already has some limitations, because many questions we are interested in cannot be answered within “The Analects of Confucius.” For example, The Analects of Confucius basically discussed the matters in China, however considering all possible situations it should matter in foreign countries as well, i.e. the “global village.” This was impossible in Confucian …

Ecological Benefits Of Mitigation On A Large River Mainstem In An Intensively Mined Appalachian Watershed, Eric Mitchell Miller

Graduate Theses, Dissertations, and Problem Reports (ETD)

Large scale surface mining in the central Appalachians causes significant alteration of headwater catchments, and these impacts may be offset through implementation of stream restoration projects. As an example, several habitat enhancement structures (cross-vanes and j-hooks) were constructed along a 13.7 km section of the Little Coal River as mitigation for mining impacts in the region. The objectives of our study were to: 1-quantify changes in channel morphology, habitat quality, sediment composition, bank stability, biological communities and organic matter processing in response to habitat enhancing structures; 2-relate changes in structural and functional attributes of the Little Coal River mainstem to …

Exploring Us Textbooks’ Treatment Of The Estimation Of Linear Measurements, Kuo-Liang Chang, Lorraine Males, Aaron Mosier, Funda Gonulates

Department of Teaching, Learning, and Teacher Education: Faculty Publications

Learning to estimate a linear measurement is critical in becoming a successful measurer. Research indicates that the teaching of the estimation of linear measurement is quite open and that instruction does not make explicit to students how to carry out estimation work. Because written curriculum has been identified as one of the main sources affecting teachers’ instruction and students’ learning, this study examined how estimation of linear measurement tasks were presented to students in three US elementary mathematics curricula to see how much and in what ways these tasks were presented in an open manner. The principal result was that …

The Importance Of School Culture In The Advancement Of 21st Century Learning Environments: A Qualitative Study., Lydotta M. Taylor

This qualitative study aims to make explicit the importance of school culture and teacher involvement in shaping and implementing reform efforts. Over the past 60 years, a variety of political leaders have led numerous education reform efforts. The importance of school culture has often been missing from the reform efforts. This study reviews the effectiveness of the Who Took My Chalk?â„¢ intervention and the six defining characteristics of the intervention: student engagement, collaboration, goal setting, action planning, assessing attitudes, and engaging openness. The data collected for this study include pre- and post- interview responses from school faculty on the six …

Role Of Inhibition In Binaural Processing, Jesse M. Thompson

Graduate Theses, Dissertations, and Problem Reports (ETD)

The medial and lateral superior olives (MSO, LSO) are the lowest order cell groups in the mammalian auditory circuit to receive massive binaural input. The MSO functions in part to encode interaural time differences (ITD), the predominant cue for localization of low frequency sounds. Binaural inputs to the MSO consist of excitatory projections from the cochlear nuclei (CN) and inhibitory projections from both the medial nucleus of the trapezoid body (MNTB) and lateral nucleus of the trapezoid body (LNTB). The interaction of excitatory and inhibitory currents within an MSO cell's soma and dendrites over the backdrop of its intrinsic ionic …
