Relational Specification As A Testing Oracle, Harjinder Sandhu

Graduate Theses, Dissertations, and Problem Reports (ETD)

Software engineering community is well aware of the usefulness of formal methods for specifying, designing and testing of the software. Despite this testing literature rarely deals with specification based testing. Testing from formal specifications offers a simple, structured and more rigorous approach to the functional tests than testing techniques. An important application of specification in testing is providing test oracles. The rise of use of computers in control safety critical systems, i.e., flight control systems, necessitates that rigorous system testing is performed before the deployment. In flight control systems, requirements are mostly concerned with the safety and maneuverability of an …

A Deafening Silence: Various School Systems' Reactions To Student Sexual Victimization By School Personnel, Marilyn K. Snyder

Theses and Dissertations

This study examined the responses of various school systems to learning of the sexual abuse of students by adult members of the school communities. The focus was on the reasons for the school systems decisions to accept or reject a report of sexual victimization of students, the levels of acceptance or rejection indicated by their reactions to the reports, and the aftermaths of the choices.

Data were gathered primarily through in-depth interviews with victims and their family members and friends, perpetrators, and school administrators, board members, and counselors. Document analysis supplemented the interviews. Themes in the data were elicited by …

Effective Bandwidth For Traffic Engineering, Mark J. Clement, Rob Kunz, Seth Nielson, Quinn O. Snell

Faculty Publications

In today’s Internet, demand is increasing for guarantees of speed and efficiency. Current routers are very limited in the type and quantity of observed data they can provide, making it difficult for providers to maximize utilization without the risk of degraded throughput. This research uses statistical data currents provided by router vendors to estimate the impact of changes in network configuration on the probability of link overflow. This allows service providers to calculate in advance, the effect of grooming on a network, eliminating the conservative trial-and-error approach normally used. These predictions are made using Large Deviation Theory, which focuses on …

Explorations In The Classification Of Vertices As Good Or Bad., Eugenie Marie Jackson

Electronic Theses and Dissertations

For a graph G, a set S is a dominating set if every vertex in V-S has a neighbor in S. A vertex contained in some minimum dominating set is called good; otherwise it is bad. A graph G has g(G) good vertices and b(G) bad vertices. The relationship between the order of G and g(G) assigns the graph to one of four classes.

Our results include a method of classifying caterpillars. Further, we develop realizability conditions for a graph G given a triple of nonnegative integers …

Radical P-Chains In L3(2)., Donald Dewayne Belcher

Electronic Theses and Dissertations

The McKay-Alperin-Dade Conjecture, which has not been finally verified, predicts the number of complex irreducible characters in various p-blocks of a finite group G as an alternating sum of the numbers of characters in related p-blocks of certain subgroups of G. The sub-groups involved are the normalizers of representatives of conjugacy classes of radical p-chains of G. For this reason, it is of interest to study radical p-chains. In this thesis, we examine the group L₃(2) and determine representatives of the conjugacy classes of radical p-subgroups and radical p-chains for …

A Data Layout Descriptor Language (Ladel)., Ashfaq Ahmed Jeelani

Electronic Theses and Dissertations

To transfer data between devices and main memory, standard C block I/O interfaces use block buffers of type char. C++ programs that perform block I/O commonly use typecasting to move data between structures and block buffers. The subject of this thesis, the layout description language (LADEL), represents a high-level solution to the problem of block buffer management. LADEL provides operators that hide the casting ordinarily required to pack and to unpack buffers and guard against overflow of the virtual fields. LADEL also allows a programmer to dynamically define a structured view of a block buffer's contents. This view includes the …

Leveraging Test Measurements Into Proposing Additional Domain Tests., Radhika Turlapati

Electronic Theses and Dissertations

Accuracy and efficiency are extremely critical factors for large real-time control applications. A small oversight can cause catastrophic failure of a real-time system. Thus, these applications have to be tested meticulously to prevent any catastrophe that might occur. But, testing these applications exhaustively is not tractable, mainly due to the inherent complexity of the applications and also the huge amount of inputs and outputs that these applications involve. In order to save valuable amounts of time and resources, automated testing is imperative. Also, quantitative metrics have to be provided that assess the existing quality of the system and help increase …

In-Situ Spectroscopic Studies Of Electronic Processes In Buckminsterfullerene Thin Films, Gordon Chambers

Doctoral

This study attempts to develop an understanding of the electronic processes active within the solid state of C60. The emphasis throughout the work has been upon the generation and spectroscopic identification of any species, which could potentially contribute to electronic conduction in thin films of C60. The relative importance of these inter-and intramolecular processes in terms of their contribution to the electronic transport is discussed through the comparison of the properties of the molecule with the properties of the bulk solid

Initially the low intensity optical properties of the C60 molecule in solution and in solid were assessed. Vibrational spectroscopy …

Intensification In A Risky Environment: The Case Of Improving Private Grazing Land For Beef Production In Utah, Louise D. Sainsbury

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Utah ranchers commonly face risks to their livelihoods. The objective of this work was to determine if ranchers could make profitable improvements to private land forage given the combined threat of low beef prices, drought, and possible loss of public grazing.

We used linear programming (LINDO) to identify the most profitable solutions for private land investment with an 11-year simulation. Operations were divided into small, medium, and large size classes. Various forage improvements and public permits were options. Two phases of a beef price cycle (peak and trough) and 2 precipitation patterns (wet and drought) were combined as joint favorable …

Idmp-Based Fast Handoffs And Paging In Ip-Based Cellular Networks, Archan Misra, Subir Das, Ashutosh Dutta, Sajal K. Das

Research Collection School Of Computing and Information Systems

We consider the use of our previously proposed Intra-Domain Mobility Management Protocol (IDMP) in fourth-generation mobile networks. On evaluating the heterogeneous access technologies, cellular layouts, and application characteristics of 4G environments, we realize a need to reduce both handoff latency and the frequency of mobility-related signaling. We first present IDMP's fast intradomain handoff mechanism that uses a duration-limited proactive packet multicasting solution. We quantify the expected buffering requirements of our proposed multicasting scheme for typical 4G network characteristics and compare it with alternative IP-based fast handoff solutions. We also present a paging scheme under IDMP that replicates the current cellular …

Scheduling Flexible Flowshops With Sequence -Dependent Setup Times, Kanchana Sethanan

Exploring The Effectiveness Of Self-Management Programs For Students With Disruptive Behaviors: A Comprehensive Literature Review, Heidi Kupiec

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Disruptive behaviors exhibited by children and youth pose a major problem for students exhibiting the behaviors, their peers, parents, and teachers. Disruptive behaviors including shouting, aggression, off-task behaviors, and noncompliance, correlate with poor social skills, low peer acceptance, higher rates of academic deficiencies, and in adulthood instability in relationships and employment. Self-management programs employ traditional behavior management methods and with self-management components to teach students to self-monitor or evaluate their behavior. By teaching students to be aware of and to manage their own behavior students may be better able to generalize appropriate behaviors to other less supervised settings, complete more …

Stress Concentration Around Dowel Bars In Jointed Rigid Concrete Pavements, Mourad Youssef Riad

Graduate Theses, Dissertations, and Problem Reports (ETD)

In this study, the magnitude and state of stresses induced around dowel bars were identified through detailed 3D Finite Element (3DFE) modeling of dowel jointed rigid pavement structures. Both straight and skewed joints were modeled using extremely fine meshing that allows accurate modeling of the friction and separation at dowel concrete interfaces. The model response was examined for the case of joint loading with an equivalent axle load of 18000 lb. It was found that significantly large tensile stresses develop in the concrete on both sides of the loaded dowel. The magnitude of the tensile stress approaches the tensile modulus …

A Study Of Parental Involvement At A Blue Ribbon Elementary School On The Texas-Mexico Border, Jay Scott Hollinger

Theses and Dissertations - UTB/UTPA

The involvement of parents in their children's education influences student achievement. In 1995, researchers identified mechanisms necessary for effective parent involvement. Although substantial research has been done on parent and family involvement, few studies have described the phenomenon among low socioeconomic Mexican-American families. In 1996, one case study was conducted at a high school and another was conducted at a middle school on the Texas-Mexico border. These studies described strategies and tactics used by the principal, teachers, and support staff to influence parents to become more involved in their children's education. The present study expands on these works by investigating …

A Natural Channel Design To Restore The Greenwater River, Washington, Gregory J. Laurie

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Channelization of the Greenwater River has resulted in a loss of habitat for Chinook salmon, a species listed as threatened under the Endangered Species Act. In order to restore habitat for fish and other aquatic organisms, a design was developed to restore meanders to the original floodplain. The channel design process began at the watershed scale, and progressed down to the scale of the stream channel. A twelve-step design process was followed that considered the influence of watershed disturbances on channel forming processes. Trends in sediment yield were assessed using an existing landslide inventory, and changes in channel pattern were …

Characteristics Of Nest Sites Of Northern Bobwhites In Western Oklahoma, Darrell E. Townsend Ii, Ronald E. Masters, Robert L. Lochmiller, David M. Leslie Jr., Stephen J. Demaso, Alan D. Peoples

United States Geological Survey: Staff Publications

Previous authors have described nesting habitat of the northern bobwhite (Colinus virginianus) throughout its range, but few have compared structural or compositional differences of vegetation between nest sites and random non-use sites, and successful and non-successful nests. From 1996-1998, we compared cover and structure of 85 plant species from 80 nest sites of northern bobwhite in western Oklahoma. Nest sites were consistently associated with greater structural complexity than what was available at random. Bobwhites selected nest sites with a greater coverage of grass (ca. 50%) and woody (ca. 20-30%) vegetation with a relatively low percentage of bare ground, …

Search For The Supersymmetric Partner Of The Top Quark In Pp̅ Collisions At √S=1.8 Tev, T. Affolder, Kenneth A. Bloom, Collider Detector At Fermilab Collaboration

Kenneth Bloom Publications

We report on a search for the supersymmetric partner of the top quark (top squark) produced in tt̅ events using 110 pb^-1 of pp̅ collisions at √s =1.8 TeV recorded with the Collider Detector at Fermilab. In the case of a light top squark, the decay of the top quark into a top squark plus the lightest supersymmetric particle (LSP) could have a significant branching ratio. The observed events are consistent with standard model tt̅ production and decay. Hence, we set limits on the branching ratio of the top quark decaying into a top squark plus LSP, excluding branching …

A Landau-Ginzburg Description Of Sb Overlayers, Ralph Skomski, T. Komesu, H.-K. Jeong, C.N. Borca, Peter A. Dowben, D. Ristoiu, J.P. Nozieres

Peter Dowben Publications

The spin polarization of Sb overlayers on the semi-Heusler alloy NiMnSb is investigated in terms of the Landau-Ginzburg approach. The half-metallic semi-Heusler alloy NiMnSb acts as a ferromagnetic perturbation and induces a spin polarization in the semimetallic Sb overlayer. Using a Gaussian approximation, the propagation of the spin perturbation in the overlayer is calculated. The results are compared with spin-polarized inverse photoemission spectroscopy (SPIPES) results and with recent spin-dependent envelope-function approximation (SDEFA) predictions. The Landau-Ginzburg parameters are both band-structure and temperature dependent, and it is argued that thermal spin excitations lead to an injection depth decreasing as 1//T law at …
