Optical Modelling of Thin Films: Applying Effective Medium Theory to Mixtures of TiO₂ and SnO₂

Creator:: Wulf, Julian J.
Abstract:: This study used SCOUT optical modelling software to create models of the reflectance and transmittance spectra generated by mixtures of titanium dioxide (TiO2) and tin oxide (SnO2). These models enabled identification of how altering the ratio of a mixture changes the optical response. By being able to identify how altering...

Beating Modes in Protostellar Disks

Creator:: Varga, Attila V.
Abstract:: Computational simulations of disks are becoming an important tool to predict the the evolution of protostars and disks to better understand the formation of planets. Past research has shown that the evolution of disks and their protostar can be altered through the interaction between gravity and hydrodynamic instabilities. We perform...

Project BoxSand : Impact of Online Course Material and Mastering Physics Interactions on Exam Performance in a Flipped Classroom Environment

Creator:: Bigelow, Jake J.
Abstract:: A flipped classroom provides students with course content in the form of videos, readings, and/or simulations that they complete during the time traditionally used for homework assignments while in-class time is devoted to hands-on group learning activities. Project BoxSand is gathering quantitative data on how students in a flipped classroom,...

Fabrication and optical measurement of flip-chips for noninvasive electrostatic gating of nanomaterials

Creator:: Nichols, Dublin MacCray
Abstract:: Electrostatic gating of nanomaterials allows researchers to control carrier density and shape potential barriers that confine carriers. Lithographic patterning followed by metal deposition is the standard technique to define electrostatic gates; however, the methods of fabricating these devices often involve harsh processing. For example, taking a material to high temperatures...

A Generalized Scheme for Creating Regge Calculus Models of General Relativity

Creator:: Hanson, Ben R.
Abstract:: Solutions to Einstein's equations are usually found by considering ideal, simplified models. However, if the real world always matched ideal physics models, then farmers would milk black and white spheres. To combat this, Regge calculus was developed as a numerical approximation scheme for general relativity. In Regge calculus curved manifolds...

Cancer Cell Detection with Mask R-CNN

Creator:: Wong, Ryan
Abstract:: Instance segmentation, the classification and localization of objects in an image, is a problem in cellular biophysics due to the physiological relevance of cell morphology. Particularly, cancer cells migrate in tissue space by changing their body shape similarly to how humans extend their limbs to swim through water. Monitoring such...

Development of a Brownian Motion Experiment for an Undergraduate Laboratory Course

Creator:: Wennstrom, Elena
Abstract:: A new class at Oregon State, PH 317: Experimental Physics, is designed to simulate a traditional laboratory research experience for undergraduate students. Several weeks of the class is devoted to Brownian motion experiments. Although this is a common topic for undergraduate lab classes, the experiment still needed some basic exploration...

Detecting Nanohertz Gravitational Waves by Searching for and Timing Millisecond Pulsars

Creator:: Nye, Brandon J.
Abstract:: Detecting gravitational waves is a topic at the forefront of physics. The first gravitational wave was detected by LIGO in 2015. This wave had a frequency in the 10s of Hz. This project is focused on detecting gravitational waves on the nanohertz spectrum using a pulsar timing array. This array...

Searching for Pulsars for Use in Gravitational Wave Detection

Creator:: Connolly, Genevieve J.
Abstract:: Gravitational waves (GWs) are disturbances in spacetime that can be caused by events such as black hole mergers and supernovae, as well as continuous sources such as binary star systems. GWs offer a new avenue of astrophysical research and can reveal information about the early universe. GW detection can be...
