Quantifying Complex Systems Via Computational Fly Swarms, Troy Taylor
Quantifying Complex Systems Via Computational Fly Swarms, Troy Taylor
Senior Theses
Complexity is prevalent both in natural and in human-made systems, yet is not well understood quantitatively. Qualitatively, complexity describes a phenomena in which a system composed of individual pieces, each having simple interactions with one another, results in interesting bulk properties that would otherwise not exist. One example of a complex biological system is the bird flock, in particular, a starling murmuration. Starlings are known to move in the direction of their neighbors and avoid collisions with fellow starlings, but as a result of these simple movement choices, the flock as a whole tends to exhibit fluid-like movements and form …
The Computational Study Of Fly Swarms & Complexity, Austin Bebee
The Computational Study Of Fly Swarms & Complexity, Austin Bebee
Senior Theses
A system is considered complex if it is composed of individual parts that abide by their own set of rules, while the system, as a whole, will produce non-deterministic properties. This prevents the behavior of such systems from being accurately predicted. The motivation for studying complexity spurs from the fact that it is a fundamental aspect of innumerable systems. Among complex systems, fly swarms are relatively simple, but even so they are still not well understood. In this research, several computational models were developed to assist with the understanding of fly swarms. These models were primarily analyzed by using the …
Thin Film Thermal Deposition At Various Pressures, James Kela Yee Keen Grace
Thin Film Thermal Deposition At Various Pressures, James Kela Yee Keen Grace
Senior Theses
This research was to verify the hypothesis that resistivity of metal's thin film deposited in a low-pressure environment is the same as its solid material. Thermal Evaporation is a thin film deposition technique in which metal inside a vacuum is evaporated, then deposited onto a surface. Higher quality metal films are deposited when the vacuum pressure is lower. At higher pressures, more air molecules are trapped within the layers of metal, thus increasing scattering sites and increasing the resistance. However, reaching a lower pressure requires more time and effort. In this research, films were deposited at various pressures and resistivities …
Competing Theories Of Pitch Perception: Frequency And Time Domain Analysis, Nowell Thacher Stoddard
Competing Theories Of Pitch Perception: Frequency And Time Domain Analysis, Nowell Thacher Stoddard
Senior Projects Spring 2017
Pitch perception is a phenomenon that has been the subject of much debate within the psychoacoustics community. It is at once a psychological, physiological and mathematical issue that has divided scientists for the last 200 years. My project aims to investigate the benefits and shortcomings of both the place theory and time theory approaches. This is done first by a model consistent with the long-standing focus on the frequency domain, and then by expanding to a more modern approach that functions in the time domain.
