Exploring Run-Time Reduction In Programming Codes Via Query Optimization And Caching, Venkata Krishna Suhas Nerella

Doctoral Dissertations

"Object oriented programming languages raised the level of abstraction by supporting the explicit first class query constructs in the programming codes. These query constructs allow programmers to express operations on collections more abstractly than relying on their realization in loops or through provided libraries. Join optimization techniques from the field of database technology support efficient realizations of such language constructs. However, the problem associated with the existing techniques such as query optimization in Java Query Language (JQL) incurs run time overhead. Besides the programming languages supporting first-class query constructs, the usage of annotations has also increased in the software engineering …

Design, Development And Characterization Of A Novel Neutron And X-Ray Combined Computed Tomography System, Vaibhav Sinha

Doctoral Dissertations

"Visualizing the three dimensional structure of objects (e.g. nuclear fuel, nuclear materials, explosives and bio materials) and phenomena (e.g. particle tracking) can be very important in nondestructive testing applications. Computed tomography systems are indispensable tools for these types of applications because they provide a versatile non-destructive technique for analysis. A novel neutron and X-ray combined computed tomography (NXCT) system has been designed and developed at the Missouri University of Science & Technology. The neutron and X-ray combined computed tomography system holds much promise for non-destructive material detection and analysis where multiple materials having similar atomic number and differing thermal cross …

Research Papers

To use the multivariate linear regression model, tests of hypotheses are needed. This paper gives F approximations to the widely used Wilk, Pillai, and Hotelling Lawley test statistics, and gives plots to check goodness and lack of fit, to check for outliers and influential cases, and to check whether the error distribution is multivariate normal.

The Implications Of Accountability Models Weighing The Same Student Data Differently, Neely Traylor

Online Theses and Dissertations

There is little debate about whether or not the U.S. education system is in need of reform. Some people believe that public education reform will come about with high-stakes accountability and policies like No Child Left Behind (2001). States around the nation are facing similar questions. For example, how do we best determine college and career readiness and assess the quality of the education provided by our schools? The most common indicator of quality in public schools has been achievement test scores. This study examined three elementary and two high school drafts of the Kentucky educational accountability system known as …

Gaussian Amicable Pairs, Ranthony Ashley Clark

Online Theses and Dissertations

Amicable pairs are two integers where the sum of the proper divisors of one is the other and vice versa. Since the Gaussian integers have many of the properties of the regular integers, we sought to discover whether there exist any pairs of Gaussian integers with the same property. It turns out that they do exist. In fact, some of the normal amicable pairs carry over as Gaussian amicable pairs. Also discovered are pairs that have a complex part.

Effective Methods Of Formative Assessment, Chelse Rae Bugg

Online Theses and Dissertations

The purpose of this research is to explore the implementation of formative assessment in the mathematics classroom. Formative assessment is considered to be any data-driven activity that an educator uses to help guide and improve instruction. While there is an abundance of research that concludes that formative assessment does indeed improve student achievement, practical methods of implementation are not thoroughly discussed. To partially determine which methods of formative assessment most positively impact student achievement, a study was conducted at Lafayette High School. The researcher compared two popular methods of formative assessment: daily exit slips and unit probing (pre-, middle-, and …

Increasing Automaticity, Sara Burns

Online Theses and Dissertations

Automaticity is defined as the process of developing fluency in mathematics and the ability to answer a basic math problem routinely. Automaticity is one of the most important skills that a student can possess in mathematics. While there are many ways that an educator can implement strategies to increase automaticity in the classroom, the purpose of this study was to determine which of these methods of implementation is more effective: requiring students to practice automaticity three times per week or requiring students to practice automaticity five times per week.

Online Theses and Dissertations

CONTEXT: Concussions are a major concern in sport and healthcare professionals are recognizing its profoundness in the impact it has on athletes. There may be limitations in the current approach to assessments among each individual evaluation involved; however, the combination of all three assessments adds to its strength and determining the overall understanding of the concussion and its effects. Any measure of assessment that connects underlying issues arising from concussion to help decrease long-term impairments by returning to play prematurely, risking further injury, is essential. The need for a dual-task assessment delivers an increased sensitivity to the assessment by combining …

Positive Solutions, Existence Of Smallest Eigenvalues, And Comparison Of Smallest Eigenvalues Of A Fourth Order Three Point Boundary Value Problem, Sarah Schulz King`

Online Theses and Dissertations

The existence of smallest positive eigenvalues is established for the linear differential equations $u^{(4)}+\lambda_{1} q(t)u=0$ and $u^{(4)}+\lambda_{2} r(t)u=0$, $0\leq t \leq 1$, with each satisfying the boundary conditions $u(0)=u'(p)=u''(1)=u'''(1)=0$ where $1-\frac{\sqrt{3}}{3}\le p < 1$. A comparison theorem for smallest positive eigenvalues is then obtained. Using the same theorems, we will extend the problem to the fifth order via the Green's Function and again via Substitution. Applying the comparison theorems and the properties of $u_0$-positive operators to determine the existence of smallest eigenvalues. The existence of these smallest eigenvalues is then applied to characterize extremal points of the differential equation $u^{(4)} + q(t)u = 0$ satisfying boundary conditions $u(0) = u'(p) = u''(b) = u'''(b)= 0$ where $1-\frac{

The Relationship Between Teacher Efficacy And Use Of Data To Inform Instruction In Two Turnaround Middle Schools, Peggy Conrad Petrilli

Online Theses and Dissertations

Schools across our county must ensure that an increasing percentage of students meet state-specified proficiency standards for the schools to be rated as making Adequate Yearly Progress (AYP). The longer a school fails to make AYP, the more severe are the corrective actions that must be undertaken.

This study looks at two turnaround middle schools in the western United States, which were determined to be among the lowest-performing five percent in their state. The turnaround model adopted by this school district is the transformational model of school turnaround. This model requires replacing at least 50% of the staff and principal, …

A Room Of One's Own? Accessory Dwelling Unit Reforms And Local Parochialism, Margaret F. Brinig, Nicole Stelle Garnett

Journal Articles

Over the past decade, a number of state and local governments have amended land use regulations to permit the accessory dwelling units (“ADUs”) on single-family lots. Measured by raw numbers of reforms, the campaign to secure legal reforms permitting ADUs appears to be a tremendous success. The question remains, however, whether these reforms overcome the well-documented land-use parochialism that has, for decades, represented a primary obstacle to increasing the supply of affordable housing. In order to understand more about their actual effects, this Article examines ADU reforms in a context which ought to predict a minimal level of local parochialism. …

Predictors Of The Number Of Under-Five Malnourished Children In Bangladesh: Application Of The Generalized Poisson Regression Model, Mohammad Mafijul Islam, Morshed Alam, Md Tariquzaman, Mohammad Alamgir Kabir, Rokhsona Pervin, Munni Begum, Md Mobarak Hossain Khan

Journal Articles: Biostatistics

BACKGROUND: Malnutrition is one of the principal causes of child mortality in developing countries including Bangladesh. According to our knowledge, most of the available studies, that addressed the issue of malnutrition among under-five children, considered the categorical (dichotomous/polychotomous) outcome variables and applied logistic regression (binary/multinomial) to find their predictors. In this study malnutrition variable (i.e. outcome) is defined as the number of under-five malnourished children in a family, which is a non-negative count variable. The purposes of the study are (i) to demonstrate the applicability of the generalized Poisson regression (GPR) model as an alternative of other statistical methods and …

Joint Entropy Of Continuously Differentiable Ultrasonic Waveforms, M S. Hughes, John E. Mccarthy, J N. Marsh, S A. Wickline

Mathematics Faculty Research

This study is based on an extension of the concept of joint entropy of two random variables to continuous functions, such as backscattered ultrasound. For two continuous random variables, X and Y, the joint probability density p(x,y) is ordinarily a continuous function of x and y that takes on values in a two dimensional region of the real plane. However, in the case where X=f(t) and Y=g(t) are both continuously differentiable functions, X and Y are concentrated exclusively on a curve, γ(t)=(f(t),g(t)), in the x,y plane. This concentration can only be represented using a mathematically "singular" object such as a …
