Light And Truth: Measuring Unseen Harm In Individuals And Communities, Hannah Pfost
Light And Truth: Measuring Unseen Harm In Individuals And Communities, Hannah Pfost
Undergraduate Honors Theses
While the fields of physics and international development may seem disparate, the insights gained from studying each one of them can improve understanding of the other. Here, I demonstrate that concept as applied to computational optics and historical memory. Thus, the purpose of this project is threefold: (1) to computationally model light transport through tissue, and use that model to inform choices about a physical system; (2) to determine the types of historical memory recommended in the final reports of truth commissions; and (3) to give evidence for the usefulness of human-centered design in both areas. To model light transport, …
Computational Development Of A Miniature Quantum Dot Spectrometer For Use In Space, Joseph Richardson
Computational Development Of A Miniature Quantum Dot Spectrometer For Use In Space, Joseph Richardson
Undergraduate Honors Theses
Miniature spectrometers are of great interest to NASA as necessary instrumentation is scaled down and optimized for specific space application. Semiconductor nanocrystals called quantum dots (QD) are being used to create a miniature high-resolution filter-based spectrometer, with the goal of use in space within 5 years. Computational imaging techniques— such as automated image analysis and mathematical spectrum reconstruction algorithms—are key to making the QD spectrometer a reality. This thesis will discuss the process of developing these computational methods, along with the improvements that have occurred from previous work.
Emergent Properties Of The Transport Of Sand, Eric Lenhart
Emergent Properties Of The Transport Of Sand, Eric Lenhart
Undergraduate Honors Theses
In the interest of drawing conclusions about Aeolian environments based on remote imaging, we investigated how air flow forms self-organizing patterns, such as ripples, across loose particulate surfaces. Specifically, we analyzed various models of sand transport, particularly Nishimori’s model, to note the effects of altering various parameters, including wind direction, saltation length, diffusion, and a saltation proportionality constant. As a measure of the frustration of the emergent patterns, Y-junctions were counted at various values of the parameters. A strong correlation with the saltation proportionality constant and no correlation with the saltation height were found. As an additional use of the …
