The reaction of zinc chloride with Mn is conducted in both Cu and alumina pans. It was postulated that zinc chloride might be reacting with Cu in Cu pan. The reaction between zinc chloride and Mn is also observed. The reactions of chromium chloride and chromium chloride hexahydrate with Zn and Mn are conducted in Cu pans. The obtained TG/DTA plots showed reactions in all the cases. The reactions with chromium chloride hexahydrate are observed …

A Reusable Persistence Framework For Replicating Empirical Studies On Data From Open Source Repositories, Scott Bong-Soo Chun

Theses and Dissertations

Empirical research is inexact and error-prone leading researchers to agree that replication of experiments is a necessary step to validating empirical results. Unfortunately, replicating experiments requires substantial investments in manpower and time. These resource requirements can be reduced by incorporating component reuse when building tools for empirical experimentation. Bokeo is an initiative within the Sequoia Lab of the BYU Computer Science Department to develop a platform to assist in the empirical study of software engineering. The i3Persistence Framework is a component of Bokeo which enables researchers to easily build and rapidly deploy tools for empirical experiments by providing an easy-to-use …

Large Scale Application Of Vibration Sensors For Fan Monitoring At Commercial Layer Hen Houses, Ji-Qin Ni, Yan Chen, Claude A. Diehl, Albert J. Heber, Bill W. Bogan, Li-Long Chai

School of Agricultural & Biological Engineering Faculty Publications

Continuously monitoring the operation of each individual fan can significantly improve the measurement quality of aerial pollutant emissions from animal buildings that have a large number of fans. To monitor the fan operation by detecting the fan vibration is a relatively new technique. A low-cost electronic vibration sensor was developed and commercialized. However, its large scale application has not yet been evaluated. This paper presents long-term performance results of this vibration sensor at two large commercial layer houses. Vibration sensors were installed on 164 fans of 130 cm diameter to continuously monitor the fan on/off status for two years. The …

Capture And Access Of Multiple Screen Presentations, Kelv H. Cutler

Theses and Dissertations

Knowledge transferred during meetings is often ephemeral in nature and thus must be captured if it is to be retained. Ideally, a capture solution should be able to 1) accommodate any number of screens without sacrificing image quality and 2) allow dynamic access to a complete media capture while the capture is taking place. Both students and employees can benefit from the information captured during the lectures and meetings for enhanced discussion and afterward for knowledge retention. Current systems do not support multiple screen capture well, and no system supports dynamic access to the active meeting capture during the meeting. …

Sequence Stratigraphy Of The Lower Pennsylvanian (Bashkirian, Morrowan) Round Valley Limestone, Split Mountain Anticline (Dinosaur National Monument) And In The Eastern Uinta Mountains, Utah, Nathan Robert Davis

Theses and Dissertations

The Early Pennsylvanian (Bashkirian/Morrowan) Round Valley Limestone of northeastern Utah was deposited on the Wyoming shelf, a slowly subsiding depositional surface located between the Eagle and Oquirrh basins. The 311-foot-thick Round Valley Limestone displays a distinct cyclicity formed by stacked, meter-scale parasequences, comprised of a limited suite of open- to restricted-marine limestones with minor interbeds of siltstone and shale. Open-marine deposits are characterized by mudstone and heterozoan wackestone-packstone microfacies (MF1-4) and comprise the lower portions of parasequences. Rocks of these microfacies were deposited during maximum high-order transgression of the shelf. As sediment filled the limited accommodation, the shelf became restricted, …

Eit, Slow Light, And Sealing Methods For Embedding Rubidium Into The Arrow System, Katherine Barnett Hurd

Theses and Dissertations

Light-matter interactions are fundamentally based on the quantum mechanical principles that govern photons, electrons and other fundamental particles. One very interesting phenomenon within all of light-matter interactions is Electromagnetically Induced Transparency(EIT). This phenomenon causes an otherwise absorbing atomic transition to stop absorbing through quantum mechanical interference of probability wave functions. Corresponding to that change in absorption, will be a sudden, large change in the index of refraction. This change in the index of refraction leads to another phenomenon in which the group velocity of light can be slowed down dramatically. In the past, many researchers have been able to achieve …

An Evaluation Of Multiple Choice Test Questions Deliberately Designed To Include Multiple Correct Answers, Kim Scott Thayn

Theses and Dissertations

The multiple-choice test question is a popular item format used for tests ranging from classroom assessments to professional licensure exams. The popularity of this format stems from its administration and scoring efficiencies. The most common multiple-choice format consists of a stem that presents a problem to be solved accompanied by a single correct answer and two, three, or four incorrect answers. A well-constructed item using this format can result in a high quality assessment of an examinee's knowledge, skills and abilities. However, for some complex, higher-order knowledge, skills and abilities, a single correct answer is often insufficient. Test developers tend …

Dynamical Grouping In Complex Systems, Zhenyuan Zhao

Open Access Dissertations

Quantifying the behavior of complex systems arguably presents the common ¡°hard¡±problem across the physical, biological, social, economic sciences. Individual-based or agent-based models have proved useful in a variety of different real world systems: from the physical, biological, medical domains through to social and even financial domains. There are many different models in each of these fields, each with their own particular assumptions, strengths and weaknesses for particular application areas. However, there is a lack of minimal model analysis in which both numerical and analytic results can be obtained, and hence allowing different application domains to be analyzed on a common …

The game theory methodology is used …

Warped Product Einstein Metrics Over Spaces With Constant Scalar Curvature, Chenxu He, Peter Petersen, William Wylie

Mathematics - All Scholarship

In this paper we study warped product Einstein metrics over spaces with constant scalar curvature. We call such a manifold rigid if the universal cover of the base is Einstein or is isometric to a product of Einstein manifolds. When the base is three dimensional and the dimension of the fiber is greater than one we show that the space is always rigid. We also exhibit examples of solvable four dimensional Lie groups that can be used as the base space of non-rigid warped product Einstein metrics showing that the result is not true in dimension greater than three. We …

Evaluation Real-Time Data Warehousing Challenges From A Theoretical And Practical Perspective, Dale Hargens

Regis University Student Publications (comprehensive collection)

The concept of real-time data warehousing has grown in popularity in recent years as organizations demand access to critical pieces of data in real-time to produce analytics and make business decisions to gain competitive advantage. Real-time data warehousing systems differ substantially from traditional data warehousing systems, thus, presenting a unique set of organizational and operational challenges. The basis for the research was to investigate whether adequate information is available regarding the organizational and operational challenges of real-time data warehousing and whether that information is available to the database community. This exploration was done by gathering primary research, conducting a case …

Evaluation Of Hydraulic Efficiency Of Disinfection Systems Based On Residence Time Distribution Curves, Jordan M. Wilson, Subhas K. Venayagamoorthy

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

Hydraulic efficiency is a vital component in evaluating the disinfection capability of a contact system. Current practice evaluates these systems based upon the theoretical detention time (TDT) and the rising limb of the residence time distribution (RTD) curve. This evaluation methodology is expected because most systems are built based on TDT under a "black box" approach to disinfection system design. Within recent years, the proliferation of computational fluid dynamics (CFD) has allowed a more insightful approach to disinfection system design and analysis. Research presented in this study using CFD models and physical tracer studies shows that evaluation methods based upon …

The Vinylguaiacol/Indole Or Vgi ("Veggie") Ratio: A Novel Molecular Parameter To Evaluate The Relative Contributions Of Terrestrial And Aquatic Organic Matter To Sediments., Michael A. Kruge, Kevin K. Olsen, Jaroslaw W. Slusarczyk, Elaine Gomez

Department of Earth and Environmental Studies Faculty Scholarship and Creative Works

The organic matter (OM) fraction of estuarine sediments is often distinctive and thus diagnostically useful in determinations of sedimentary provenance. Among the most fundamental distinctions to be made is that between terrestrial and aquatic OM. To supplement the parameters commonly used for this purpose (e.g., C/N and stable isotope ratios), we proposed the Vinylguaiacol/Indole or VGI ("Veggie") ratio, defined as [vinylguaiacol / (indole + vinylguaiacol)] using data produced by analytical pyrolysis-gas chromatography/mass spectrometry of dried, homogenized sediment samples. The ratio employs the peak areas of these two compounds on the mass chromatograms of their molecular ions (m/z 150 and 117). …

ABSTRACT Stephen K. Biermann PERCEPTIONS OF EFFECTIVE INSTRUCTION IN COMMUNITY COLLEGES: A STUDENT VIEW This qualitative study was designed to identify key elements of effective instruction as perceived by community college students. Since the majority of research pertaining to effective instruction has been primarily conducted using a quantitative format, it is important to consider other methodologies for future research. The use of qualitative research helped capture student dialogue in its fullest, unhindered by the constraints of a survey tool or scale. The students involved in the study voluntarily participated in either individual interviews or focus groups and commented upon various …

Representation And Validation Of Domain And Range Restrictions In A Relational Database-Driven Ontology Maintenance System, Patrick G. Edgett, Leong Lee, Jennifer L. Leopold, Alton B. Coalter

Computer Science Faculty Research & Creative Works

An ontology can be used to represent and organize the objects, properties, events, processes, and relations that embody an area of reality [1]. These knowledge bases may be created manually (by individuals or groups), and/or automatically using software tools, such as those developed for information retrieval and data mining. Recently the National Science Foundation funded a large collaborative development project for the semi-automated construction of an ontology of amphibian anatomy (AmphibAnat [2]). to satisfy the extensive community curation requirements of that project, a generic, Web-Based, multi-user, relational database ontology management system (RDBOM [3]) was constructed, based upon a novel theoretical …

The Role Of Discriminatory Experiences On Hispanic Students’ College Choice Decisions, Amanda Taggart, Gloria Crisp

Teacher Education and Leadership Faculty Publications

This study examined the impact of discriminatory experiences on Hispanic students’ decisions concerning postsecondary enrollment. Logistic regression was used to identify variables associated with Hispanic students’ decisions to attend either a 2- or a 4-year institution within the context of theory concerning college choice/success. Data were drawn from a nationally representative sample ( n = 2,210) of Hispanic students from the ELS:2002 data set. Results indicated that Hispanic students were less likely to attend a 4-year institution if they personally experienced or perceived others being discriminated against during high school. Findings suggest that discriminatory high school experiences may contribute to …

Chaos And Universality In Two-Dimensional Ising Spin Glasses, Alan Middleton, Creighton K. Thomas, David A. Huse

Physics - All Scholarship

Recently extended precise numerical methods and droplet scaling arguments allow for a coherent picture of the glassy states of two-dimensional Ising spin glasses to be assembled. The length scale at which entropy becomes important and produces "chaos", the extreme sensitivity of the state to temperature, is found to depend on the type of randomness. For the $\pm J$ model this length scale dominates the low-temperature specific heat. Although there is a type of universality, some critical exponents do depend on the distribution of disorder.

An Adaptive Coverage Control Algorithm For Deployment Of Nonholonomic Mobile Sensors, Chaouki T. Abdallah, Jose Marcio Luna, Rafael Fierro, John Wood

Electrical & Computer Engineering Faculty Publications

We show the Lyapunov stability and convergence of an adaptive and decentralized coverage control for a team of mobile sensors. This new approach assumes nonholonomic sensors rather than the usual holonomic sensors found in the literature. The kinematics of the unicycle model and a nonlinear control law in polar coordinates are used in order to prove the stability of the controller applied over a team of mobile sensors. The convergence and feasibility of the coverage control algorithm are verified through simulations in Matlab. Furthermore, some experiments are carried out using a team of four Pioneer 3-AT robots sensing a piecewise …

An Algorithm For Predicting Attitudes Of Floating Bodies With Arbitrary Configurations In Liquids, Jiann-Lin Chen, Chun-I Chen, Li-Ming Chu

Journal of Marine Science and Technology–Taiwan

A robust and efficient algorithm is proposed to quasiunsteadily predict attitudes of floating bodies with arbitrary configurations. Numerical techniques for accuracy and computing time saving are addressed. A floating cylinder was modeled as a benchmark, by theoretical and experimental approaches, to validate the developed program. Attitudes of two kinds of floating bodies, which are a body composed of multiple objects and a submarine-like submersible, were simulated to show the feasibility of the present algorithm. Interestingly, the simulated results of a slender body, such as a cylinder or a submersible, show that the attitude variation is very sensitive to the longitudinal …
