Investigating The Effect Of An Upstream Spheroid On Tandem Hydrofoils, Joel Tynan Guerra
Investigating The Effect Of An Upstream Spheroid On Tandem Hydrofoils, Joel Tynan Guerra
Master's Theses
This thesis documents a series of three dimensional unsteady Reynolds Averaged Navier-Stokes CFD simulations used to investigate the influence of an upstream prolate spheroid body on tandem pitching hydrofoils. The model is validated by performing separate CFD simulations on the body and pitching hydrofoils and comparing results to existing experimental data. The simulations were run for a range of Strouhal numbers (0.2-0.5) and phase differences (0-π). Results were compared to identical simulations without an upstream body to determine how the body affects thrust generation and the unsteady flow field.
The combined time-averaged thrust increases with Strouhal number, and is highest …
Compartmentalization Of Dna-Based Molecular Computing Elements Using Lipid Bilayers, Aurora Fabry-Wood
Compartmentalization Of Dna-Based Molecular Computing Elements Using Lipid Bilayers, Aurora Fabry-Wood
Biomedical Engineering ETDs
This dissertation will present a progression from the detection of double-stranded DNA using a combination of toehold-mediated strand displacement and DNAzyme reactions in dilute saline solutions, to the generation of separate compartments to allow standardization of DNA computing elements, by protecting from complementary strands. In well-mixed solutions complementary regions cause spurious interactions. Importantly, these compartments also provide protection from nucleases. Along the way we will also explore the use of silica microsphere supported lipid bilayers to run compartmentalized DNA reactions on a fluid surface and the design of a molecule capable of DNA-based transmembrane signal transduction.
Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender
Radical Social Ecology As Deep Pragmatism: A Call To The Abolition Of Systemic Dissonance And The Minimization Of Entropic Chaos, Arielle Brender
Student Theses 2015-Present
This paper aims to shed light on the dissonance caused by the superimposition of Dominant Human Systems on Natural Systems. I highlight the synthetic nature of Dominant Human Systems as egoic and linguistic phenomenon manufactured by a mere portion of the human population, which renders them inherently oppressive unto peoples and landscapes whose wisdom were barred from the design process. In pursuing a radical pragmatic approach to mending the simultaneous oppression and destruction of the human being and the earth, I highlight the necessity of minimizing entropic chaos caused by excess energy expenditure, an essential feature of systems that aim …

Nature is a constant source of inspiration for engineers and scientists through its simple, effective, and elegant solutions to many complex problems. Smart materials and soft robotics have been seen to be particularly well suited for developing biomimetic devices and are active fields of research. In this study, the design, modeling, and optimization of a new biomimetic soft robot is described. Preliminary work was made in the modeling of a biomimetic robot based on the locomotion and kinematics of jellyfish. Modifications were made to the governing equations for jellyfish locomotion that accounted for geometric differences between biology and the robotic …
