A necessary and sufficient condition under which the weight w : E → R⁺ on the graph G has a unique continuation to a metric d : V x V → R⁺ is found.

On Rainbow Cycles And Proper Edge Colorings Of Generalized Polygons, Matt Noble

Theory & Applications of Graphs

An edge coloring of a simple graph G is said to be proper rainbow-cycle-forbidding (PRCF, for short) if no two incident edges receive the same color and for any cycle in G, at least two edges of that cycle receive the same color. A graph G is defined to be PRCF-good if it admits a PRCF edge coloring, and G is deemed PRCF-bad otherwise. In recent work, Hoffman, et al. study PRCF edge colorings and find many examples of PRCF-bad graphs having girth less than or equal to 4. They then ask whether such graphs exist having girth greater than …

Supporting Spatial Reasoning: Identifying Aspects Of Length, Area, And Volume In Textbook Definitions, Eryn M. Stehr Maher, Jia He

Mathematical Sciences: Faculty Publications

Length, area, and volume share structural similarities enabling flexibility in reasoning for real-world applications. Deep understanding of structures can help teachers connect these concepts to support their students’ mathematical reasoning and practices involving real-world situations. In mathematics textbooks designed for future teachers, definitions of length, area, and volume vary from procedural (e.g., use a ruler to measure side lengths, use formulas to calculate measures) to conceptual (e.g., construct appropriate n-dimensional units that tessellate the n-dimensional space) to formal (e.g., construct a function mapping qualitative size to a quantity of appropriate units). Most textbooks describe length, area, and volume …

Fabrication And Investigation Of Microfluidic Devices That Produce Non-Linear Chemical Gradients, Elijah L. Waters

College of Graduate Studies: Theses & Dissertations

Investigation of cell chemotaxis requires controlled chemical gradients. We investigated microfluidic devices that could enhance small populations' cell assays because of their ability to generate various chemical gradients. Our five designs generate different chemical concentration landscapes that we can easily convert into tools to study cell response to growth factors. Gradient landscapes occurred by splitting and mixing two input fluid concentrations using bifurcations, trifurcations, and Y-mixing junctions in three consecutive steps. Such fluid flow manipulations resulted in nine concentration streams entering a 0.54-mm-wide gradient chamber. The first design used a 1:1 ratio Y-mixer (unbiased) when blending two concentrations, resulting in …

Endogenous Antioxidant Response And Lipid Peroxidation Levels In Muscle Tissue Of The Cownose Ray (Rhinoptera Bonasus), Bailey Berry

College of Graduate Studies: Theses & Dissertations

Oxidative stress is the result of an imbalance between reactive oxygen species (ROS) and antioxidant response within cells. ROS generation is a natural consequence of ETC activity within the mitochondria and is associated with aerobic metabolism. Oxidative stress data on elasmobranch muscle is limited, with previous studies primarily focusing on mammalian and teleost muscle. Elasmobranch skeletal muscle is generally composed of large proportions of white muscle fibers (anaerobic), low proportions of red muscle fibers (aerobic), and low proportions of pink muscle fibers (anaerobic). The cownose ray, a benthopelagic batoid species, presents an interesting model of study because it contains relatively …

Campus Safety Data Gathering, Classification, And Ranking Based On Clery-Act Reports, Walaa F. Abo Elenin

College of Graduate Studies: Theses & Dissertations

Most existing campus safety rankings are based on criminal incident history with minimal or no consideration of campus security conditions and standard safety measures. Campus safety information published by universities/colleges is usually conceptual/qualitative and not quantitative and are based-on criminal records of these campuses. Thus, no explicit and trusted ranking method for these campuses considers the level of compliance with the standard safety measures. A quantitative safety measure is important to compare different campuses easily and to learn about specific campus safety conditions.

In this thesis, we utilize Clery-Act reports of campuses to automatically analyze their safety conditions and generate …
