The behavior of small atomics cluster largely depends on their geometry,
due to the high ratio of surface atoms to interior atoms. One interesting aspect
to study clusters centers around characterizing the transition behavior between
nite and bulk materials, where the ratio of surface atoms to interior atoms is
very...
In this paper, I used a linguistic lens of translanguaging and semiotics to examine how K-12 mathematics teacher candidates (TCs) create meaning around computer science (CS) and mathematics concepts in a computational thinking (CT) setting. I defined the term “disciplinary repertoire” as a mirror to the concept of a linguistic...
The Introductory Physics 20X series has developed an advanced, metacognitive curriculum which requires a high degree of active learning in order for students to succeed in the class. Recently, the series has been transferred to the online campus, Ecampus, and is now available for distance learners. My work is focused...
ThermoSolver is an educational thermodynamics software program designed to be both
easy to use and useful in that it permits the user to make nontrivial chemical engineering
thermodynamic calculations. The software program accompanies the textbook
Engineering and Chemical Thermodynamics by Milo Koretsky, and is available for free
download from the...
Learning about periodic and oscillatory systems is a huge step in an undergraduate's
comprehensive understanding of physics and complex systems such as solids. However,
understanding how specific changes to such a system affect aspects of the entire system can
be difficult. The goal of this study is to create a...
Inertial microfluidics refers to the manipulation of the location and velocity of particles suspended in microscale fluid flow without the introduction of outside forces. It has promising applications in flow cytometry and other biomedical technologies because of the potential for lowering cost and complexity relative to current particle focusing methods....
Artificial collectives are useful for accomplishing tasks that require teamwork from multiple simple robots. Multiple robot and collective testbeds have been developed, yet none stay committed to leverage the local interactions, group size, and imperfect information assumptions that strengthen biological collectives. A review of the collective and multiple robot literature,...
Using research on student motivation as well as Project-Based Learning as a theoretical framework, this thesis outlines the creation process for a set of curricula. These curricula were designed to address topics of markedly low student motivation in the first term of an introductory physics with calculus course (PH 211)...
Optical tweezers are capable of trapping micron sized particles through the transfer of
the momentum of light. These capabilities are expanded through the use of computer
controlled holograms for beam shaping. This hologram creation is facilitated through the use of
a spatial light modulator, which is a liquid crystal device...
The potential of red blood cell (RBC) and platelet damage was studied for a novel microfluidic hemoperfusion device currently in development at Oregon State University for use in treating sepsis. COMSOL 4.4's computational fluid dynamics (CFD) module was used to examine shear rate profiles in laminar, Newtonian blood flow throughout...
