1. Ickes, Henry E. A Solid Object Floating in a Bath of Three Fluids.

Degree: MS, Mathematics, 2018, Texas State University – San Marcos

We consider a bounded container filled by three immiscible fluids and a solid object, presumably floating at one or more of the interfaces. Fluids are modeled by Caccioppoli sets. The energy in our model is assumed to come from gravity, adhesion energy, and surface tension. We shall use the theory of functions of bounded variation to show that the energy functional attains a minimum for some configurations of the fluids and solid. Advisors/Committee Members: Treinen, Raymond (advisor), Torrejon, Ricardo (committee member), Welsh, Stewart (committee member).

Subjects/Keywords: Bounded variation; Caccioppoli set; Functions of bonded variation; Numerical analysis

2. McCray, Gilbert C. Computation of Liquid Drops Geometry with Motion of the Contact Curves.

Degree: MS, Applied Mathematics, 2017, Texas State University – San Marcos

This paper covers the modeling of homogenous liquids adhering to a uniform solid surface. It is divided into two separate problems: the sessile drop on a horizontal plane, and the liquid bridge between two horizontal planes held apart at a fixed distance. We prove a volume formula for both problems. We use numerical methods to solve the differential equations that describe the surface of the liquid. We use a model to compute velocity along the contact line, which is the rate at which the liquid expands along the solid surface. We study the issue of the receding and advancing along the plate or plates. Advisors/Committee Members: Treinen, Raymond F. (advisor), Dix, Julio G. (committee member), Welsh, Stewart C. (committee member).

Subjects/Keywords: Sessile drop; Liquid bridge; Contact line; Contact angle; Geometry; Surface chemistry; Capillarity

3. Starkey, Christina M. Reflective Journaling as a Tool to Support Learning Mathematical Proof.

Degree: PhD, Mathematics Education, 2016, Texas State University – San Marcos

This study investigates how reflective writing supported students’ learning to prove in an Introduction to Advanced Mathematics course. The students submitted weekly journal entries that were composed of unstructured prompts and structured, proof-related prompts. Students’ reported benefits from the journals were coded according to Borasi and Rose’s (1989) framework for student benefits from journaling in mathematics, and students’ journals about their proof writing process were coded according to Raman’s (2003) ideas about proof writing. In the unstructured journals, students demonstrated primarily therapeutic, problem solving, and content benefits. However, students reported experiencing mostly problem solving and content benefits, as well benefits related to dialoguing with the instructor. A positive and significant correlation was found between the number of journals completed and course grade, which suggests a relationship present between the two. Over half of the students felt the journals influenced their learning to prove by helping them pin down their understandings and write about proof ideas in their own words, which they then connected to the more formal writing in their proofs. There did not seem to be a relationship between the journals and students’ views about mathematics, likely because students rarely wrote about their views related to the nature of mathematics or proving. Advisors/Committee Members: Sorto, M. Alejandra (advisor), Welsh, Stewart (advisor), Warshauer, Hiroko (committee member), White, Alexander (committee member), Wilson, Nancy (committee member).
