A Cubic Spline Projection Method for Computing Stationary Density Functions of FrobeniusPerron Operator
(2022)Stationary density functions of FrobeniusPerron operators have critical applications in many fields of science and engineering. Accordingly, approximating stationary density functions f* is important and the focus of this ... 
A decoupled scheme for a singlephase model in ferrohydrodynamics
(2024)In this Ph.D. research, we propose numerical approximations of a simplified model for single phase ferrofluid flow, which consists of the Navier–Stokes equations coupled with the Poisson equation. Using several spatial and ... 
A Longitudinal study of modelingbased college algebra and its effect on student achievement
(2020)Low success rates and high withdrawal rates in gateway courses like College Algebra have deterred some students from attaining their educational goals. The university of study developed a ModelingBased College Algebra ... 
A Mathematical Modelling Approach to Analyze the Dynamics of Math Anxiety
(2022)The main objective of this study is to develop a mathematical modeling framework for a deeper understanding of dynamics of math anxiety as a contagious process. Borrowing from theories of the spread of infectious disease, ... 
A modeling framework for spatial transmission of Covid19 in local communities
(2022)COVID19 is the recent infectious disease caused by the severe acute respiratory syndrome novel coronavirus (SARSCoV2). Because the transmissibility of the virus is relatively high and the outbreaks remained undetected ... 
A study of carbon and iron charged point defects in gallium nitride: electronic structure implications for highpower photoconductive solid state switch applications
(2021)There is growing demand for highperformance electronics in high volt age, high current, and high frequency efficiency requirements that current materials (e.g., Si) are not fulfilling. Within the last few years, the ... 
A study of homological invariants modulo an exact zero divisor
(2024)Let Q be a commutative local ring and R a quotient ring of Q by an ideal generated by an exact zero divisor. We use differential graded structures to describe a construction that produces a minimal free resolution of an ... 
Ab initio computational applications to complex biomolecular systems
(University of MissouriKansas City, 20120117)A series of biomaterial related systems ― including water and DNA molecules ― have been studied using ab initio (firstprinciples) methods. By investigating the properties of water as the preliminary step, the hydrogen ... 
Alternatively certified and traditionally certified secondary school mathematics teachers' student success on the Missouri Assessment Program
(University of MissouriKansas City, 20120514)Since the 1980s, alternative certification programs, with the goals of improving the quality and quantity of teachers, have been preparing teachers through streamlined coursework tailored to the individual teachers' ... 
Anisotropic Mesh Adaptation for Image Segmentation based on Partial Differential Equations
(2020)As the resolution of digital images increases significantly, the processing of images becomes more challenging in terms of accuracy and efficiency. In this dissertation, we consider image segmentation by solving a partial ... 
Application of Ab Initio Calculations and Molecular Dynamics to Collagen and Brome Mosaic Virus
(University of MissouriKansas City, 2016)Molecular Dynamics (MD) simulations are no more accurate than the underlying force field which represents the molecular interactions. In this thesis, we have calculated ab initio atomic partial charges for proteins of ... 
Applications of multivariate analysis to understand the dynamics of African conflicts
(2020)Africa that is known for the birthplace of humanity has become a continent of all kind of devastating conflicts. This is a major concern because these conflicts are having lasting negative impact on the socioeconomic ... 
Bayesian Change Point Analysis of Copy Number Variants Using Human Next Generation Sequencing Data
(2014)Read count analysis is the principal strategy implemented in detection of copy number variants using human next generation sequencing (NGS) data. Read count data from NGS has been demonstrated to follow non homogeneous ... 
Cohomology of Finite Modules over Short Gorenstein Rings
(2016)We study two formal power series in the indeterminate t that generalize the Poincar´e series of a module. In the context of a Gorenstein local ring whose maximal ideal m satisﬁes m³ = 0, we prove that these two power ... 
Comparative Investigation of LIBS Spectra and Crater Morphology During Laser Ablation of Eutectic BiSn Alloys
(2022)Laserbased methods such as pulsed laser deposition (PLD) that are used for fabricating structural and functional materials are ripe for dramatic improvement. However, because laser–material interactions are dependent on ... 
Comparing Multiple Measure Placement Models in Mathematics
(2020)Accurate placement into an initial college mathematics course is a key step toward the successful completion of college mathematics and, eventually, a college degree. Conversely, misplacement in mathematics may lead to a ... 
Convolutional Neural Networks for Early Diagnosing of Breast Cancer
(2022)Due to the high demand for mammograms, radiologists are swamped with many patients' mammograms. Radiologists' workload has increased dramatically over the last 15 years during oncall hours. This rise is due to an increase ... 
Design of Instrumentation and Methodologies for Determination of Free Neutron Characteristics
(University of Missouri  Kansas City, 2017)Measuring neutron source‐dependent free neutron properties over a large neutron energy range, with human‐portable instrumentation, continues to push the frontier of neutron detection instrumentation design and analysis ... 
Detecting changepoints in a Compound Poisson Process
(University of MissouriKansas City, 2012)A statistical change point problem was first studied in the mid1950s in the context of quality control in industrial processes. A change point is defined as a point in the time order when the probability distribution ... 
Development of an advanced Hybrid (U)RANS/LES turbulence models using Scale Adaptive Simulation (SAS) method
(2022)Turbulence is a ubiquitous phenomenon occurring in most practical fluid flows. The accurate prediction of turbulent flows is evident in optimizing and developing highly efficient modern fluid systems. Several turbulence ...
