Search-Based Model Summarization, Lokesh Krishna Ravichandran

Masters Theses

"Large systems are complex and consist of numerous components and interactions between the components. Hence managing such large systems is a cumbersome and time consuming task. Large systems are usually described at the model level. But the large number of components in such models makes it difficult to modify. As a consequence, developers need a solution to rapidly detect which model components to revise. Effective solution is to generate a model summary. Although existing techniques are powerful enough to provide good summaries based on lexical information (relevant terms), they do not make use of structural information (component structure) well. In …

Effect Of Mix Parameters On Longevity Of Bituminous Mixtures, Clayton Reichle

Masters Theses

"This study was performed to evaluate the effects of varying aggregate sources, aggregate gradations on the stripping and rutting potential of bituminous based plant mixes specified by the Missouri Department of Transportation. The different aggregate combinations included two different aggregate sources (Potosi Dolomite and Jefferson City Dolomite) including two variations for the Jefferson City Dolomite mix to simulate a marginally in-specification mix and an out-of-specification but in-field tolerance mix. The "field" mix simulated the marginal mix where field tolerance of high dust and low binder content were maximized. All three mixes were evaluated for stripping susceptibility using the Tensile Strength …

Secure Design Defects Detection And Correction, Wenquan Wang

Masters Theses

"Bad design and software defects often make source codes hard to understand and lead to maintenance difficulties. In order to detect and fix such defects, researchers have systematically investigated these issues and designed different effective algorithms to tackle the problems. However, most of these methods need source codes/models for defect detection and correction. Commercial companies, like banks, may not be willing to provide their source models due to data security. Therefore, it is a huge challenge to detect software detects by a consulting company as well as to keep source models confidential. This thesis analyze security issues in existing approaches …

New Sensorless, Efficient Optimized And Stabilized V/F Control For Pmsm Machines, Seyed Hesam Jafari

Masters Theses

"With the rapid advances in power electronics and motor drive technologies in recent decades, permanent magnet synchronous machines (PMSM) have found extensive applications in a variety of industrial systems due to its many desirable features such as high power density, high efficiency, and high torque to current ratio, low noise, and robustness. In low dynamic applications like pumps, fans and compressors where the motor speed is nearly constant, usage of a simple control algorithm that can be implemented with least number of the costly external hardware can be highly desirable for industry. In recent published works, for low power PMSMs, …

Broad-Spectrum Antibacterial Properties Of Metal-Ion Doped Borate Bioactive Glasses For Clinical Applications, Megan Ottomeyer

Masters Theses

"Bioactive glasses with antimicrobial properties can be implemented as coatings on medical devices and implants, as well as a treatment for tissue repair and prevention of common hospital-acquired infections such as MRSA A borate-containing glass, B3, is also undergoing clinical trials to assess wound-healing properties. The sensitivities of various bacteria to B3, B3-Ag, B3-Ga, and B3-I bioactive glasses were tested. In addition, the mechanism of action for the glasses was studied by spectroscopic enzyme kinetics experiments, Live-Dead staining fluorescence microscopy, and luminescence assays using two gene fusion strains of Escherichia coli.

It was found that gram-positive bacteria were more …

Improving Life Cycle Management Plans For Power Plant Components, Srinath Raghavan

Masters Theses

"Life cycle management (LCM) combines a set of technical and economic activities with the specific goal of improving the long term economic value of an asset. It is necessary to perform a sound LCM exercise on the utility or industrial asset to maintain the profitability of a plant. In most industries, the maintenance budget is either higher than optimal or lower than required, that result in expensive outages, damages and accidents. An LCM plan is a guide to make operational decision for a component over its life cycle. LCM typically consists of a preventive maintenance schedule, condition monitoring, inspection activities, …

Common Mode Current Estimation For Cable Bundle Inside A Vehicle, Dazhao Liu

Doctoral Dissertations

"In the Section 1, it introduces a methodology to simulate the currents and fields during an air discharge ESD into a product by combining a linear description of the behavior of the DUT with a non-linear arc resistance equation. The most commonly used test standard IEC 61000-4-2 requires using contact mode discharges to metallic surfaces and air discharge mode to non-conducting surfaces. This paper proposes a method that combines the linear ESD generator full wave model and the non-linear arc model to simulate currents and fields in air discharge mode. In Section 2, when simulating surface and thin wire structures, …

Common Host-Derived Chemicals Increase Catches Of Disease-Transmitting Mosquitoes And Can Improve Early Warning Systems For Rift Valley Fever Virus, David P. Tchouassi, Rosemary Sang, Catherine L. Sole, Armanda D.S. Bastos, Peter E.A. Teal, Christian Borgemeister, Baldwyn Torto

All Peer-Reviewed Publications

Rift Valley fever (RVF), a mosquito-borne zoonosis, is a major public health and veterinary problem in sub-Saharan Africa. Surveillance to monitor mosquito populations during the inter-epidemic period (IEP) and viral activity in these vectors is critical to informing public health decisions for early warning and control of the disease. Using a combination of field bioassays, electrophysiological and chemical analyses we demonstrated that skin-derived aldehydes (heptanal, octanal, nonanal, decanal) common to RVF virus (RVFV) hosts including sheep, cow, donkey, goat and human serve as potent attractants for RVFV mosquito vectors. Furthermore, a blend formulated from the four aldehydes and combined with …

Cannabis Use And Its Socio-Demographic Correlates Among In-School Adolescents In Zambia, Seter Siziya, Adamson S. Muula, Chola Besa, Olesegun Babaniyi, Peter Songolo, Njinga Kankiza, Emmanuel Rudatsikira

Faculty Publications

Background

Cannabis dependence in adolescents predicts increased risks of using other illicit drugs, poor academic performance and reporting psychotic symptoms. The prevalence of cannabis use was estimated two decades ago in Zambia among secondary school students. There are no recent estimates of the extent of the problem; further, correlates for its use have not been documented in Zambia. The objective of study was to estimate the current prevalence of cannabis use and its socio-demographic correlates among in-school adolescents.

Methods

We conducted secondary analysis of data that was obtained from the 2004 Zambia Global School-Based Health Survey. Logistic regression analysis was …

Alcohol Consumption And Its Correlates Among Residents Of Mining Town, Kitwe, Zambia: 2011 Population Based Survey, Cosmas Zyaambo, Olesegun Babaniyi, Peter Songolo, Adamson S. Muula, Emmanuel Rudatsikira, Seter Siziya

Faculty Publications

Alcohol consumption is a risk factor for non-communicable diseases such as cardiovascular diseases, liver cirrhosis and cancers. It has also been associated with risky sexual behaviors, hence, attributed as a factor in the increase of HIV incidence and prevalence. A cross sectional study was conducted using a modified World Health Organizations Global Non Communicable Diseases (NCD) Surveillance Initiative NCD-STEPs 1and 2. Multivariate logistic regression was used to examine the determinants of alcohol consumption. A total of 1627 individuals participated in the survey, of which 42.3% were males. Some 22.3% (36.2% of male and 12.1% of female; p<0.001) participants reported to have consumed alcohol during the 30 days preceding the survey. The factors considered to be associated with alcohol consumption were age, sex and smoking. Compared to respondents age 25-34 years, respondents of age 35-44 years were 38% (AOR = 1.38, 95%CI [1.11, 1.70]) more likely to report having consumed alcohol and those aged 45 years or older were 26% (AOR = 0.74, 95%CI [0.60, 0.93]) less likely to report having consumed alcohol. Female respondents were 47% (AOR = 0.53, 95%CI [0.46, 0.60]) less likely to report consuming alcohol compared to male respondents. Compared to respondents who reported smoking cigarettes, those who did not smoke cigarettes were 51% (AOR = 0.49, 95%CI [0.40, 0.59]) less likely to consume alcohol. The rate of alcohol consumption is high in this mining town. Factors identified in this study as associated with alcohol consumption, i.e., male sex, age, cigarette smoking, should be considered in designing interventions to curtail the level of alcohol consumption.

Self - Inflicted Serious Injuries Among Adolescents In Zambia, Adamson S. Muula, Seter Siziya, Emmanuel Rudatsikira

Faculty Publications

Injuries are a growing cause of morbidity and mortality in the world. Data from Southern Africa are limited, possibly because of limited research prioritization of the issue and pre-occupation with communicable diseases. This study was conducted to estimate the prevalence of, and assess factors associated with, self-inflicted serious injuries among in-school adolescents in Zambia. We used data collected from the 2004 Zambia Global School-Based Health Survey to estimate prevalence of self-inflicted serious injury within the past 12 months. Logistic regression analysis was conducted to assess the association between selected predictor variables and reported history of having seriously injured oneself. Out …

Social Workers As Senior Executives: Does Academic Training Dictate Leadership Style?, Lauri Goldkind, Manoj G. Pardasani

Social Service Faculty Publications

The range and patterns of leadership styles in human service organizations are important for social work educators and their students to understand if social work administrators are to compete successfully in the marketplace for executive director and other top management roles. Using a sample of executive directors of human service organizations located in a state in the Northeast section of the U.S., the Multifactor Leadership Questionnaire (MLQ) was used to explore their leadership style. The authors compare various elements of leadership style (charisma, inter-personal transactions, reactions to work issues, etc.) as well as perceptions of effectiveness and satisfaction with leadership …

On Characterizations Of Exponential Distribution Through Order Statistics And Record Values With Random Shifts, M. Ahsanullah, Imtiyaz A. Shah, George Yanev

School of Mathematical & Statistical Sciences Faculty Publications

Distributional relations of the form Y d= X +T where X, Y, and T are record values or order statistics and the random translator T is independent from X are considered. Characterizations of the exponential distribution when the ordered random variables are non-neighboring are proved. Corollaries for Pareto and power function distributions are also derived.

The Two-Phase Arterial Blood Flow With Or Without A Catheter And In The Presence Of A Single Or Multi Stenosis, Ani E. Garcia, Daniel N. Riahi

School of Mathematical & Statistical Sciences Faculty Publications

We consider the problem of blood flow in an artery with or without a catheter and in the presence of single or multi stenosis whose shape is based on the available experimental data for the stenosis in a human’s artery. The presence of stenosis in the artery, which locally narrows portion of the artery, can be a result of fatty materials such as cholesterol in the blood. The use of catheter is important as a standard tool for diagnosis and treatment in patience whose blood flow passage in the artery is affected adversely by the presence of the stenosis within …

Zero-Bounded Limits As A Special Case Of The Squeeze Theorem For Evaluating Single-Variable And Multivariable Limits, Eleftherios Gkioulekas

School of Mathematical & Statistical Sciences Faculty Publications

Many limits, typically taught as examples of applying the ‘squeeze’ theorem, can be evaluated more easily using the proposed zero-bounded limit theorem. The theorem applies to functions defined as a product of a factor going to zero and a factor that remains bounded in some neighborhood of the limit. This technique is immensely useful for both single-variable limits and multidimensional limits. A comprehensive treatment of multidimensional limits and continuity is also outlined.

On Equivalent Characterizations Of Convexity Of Functions, Eleftherios Gkioulekas

School of Mathematical & Statistical Sciences Faculty Publications

A detailed development of the theory of convex functions, not often found in complete form in most textbooks, is given. We adopt the strict secant line definition as the definitive definition of convexity. We then show that for differentiable functions, this definition becomes logically equivalent with the first derivative monotonicity definition and the tangent line definition. Consequently, for differentiable functions, all three characterizations are logically equivalent.

The Data/Information/Knowledge/Wisdom Hierarchy Goes To Seminary, Terry Dwain Robertson

Faculty Publications

In Information Science studies, the Data/Information/Knowledge/Wisdom (DIKW) hierarchy is a conventional construct for making sense of the terms. However, when examined with any rigor, the distinctions become challenged and the hierarchy appears to fail. I suggest that the reason for this is the tacit classification of this hierarchy as a disciplinary ontological narrative. With context-appropriate definitions and delimitations, the DIKW hierarchy can still be useful as a model for specific applications in information literacy pedagogy. This is illustrated in the context of theological education by using the construct to differentiate the identification of primary sources in the Seminary disciplines.

Rights In The Age Of Identity Politics, Avigail Eisenberg

Osgoode Hall Law Journal

In 1982, the Charter of Rights and Freedoms was entrenched in the Constitution at the height of what has come to be known as an era of identity politics. The influence of identity politics on Canadian jurisprudence is evident both in some of the specific rights entrenched in the Charter and in the manner these rights have been interpreted. This paper examines two approaches to Charter interpretation that use the resources of identity politics. On the identity approach, claims individuals and groups make about their identities in the course of advancing rights claims are treated as immutable, non-negotiable facts, rather …

Aboriginal And Treaty Rights And Violence Against Women, John Borrows

Osgoode Hall Law Journal

Violence against Indigenous women is a crisis of national proportions. Unfortunately, Indigenous peoples have been prevented from arguing that Indigenous communities are a constitutional site of activity for dealing with such violence. This article suggests that Aboriginal and treaty rights under section 35 of the Constitution could play a significant role in ensuring that all levels of government are seized with the responsibility for dealing with violence against women. This article explores how section 35 could be reinterpreted in ways that place issues of gender and violence at the heart of its analysis.
