Mountain View Design Project, John Barney, Sue Frye, Michaele Pride Mar 2013

Mountain View Design Project, John Barney, Sue Frye, Michaele Pride

Design and Planning Assistance Center - Projects

Mountain View is a unique community bound by the Bosque and rich history of industry, agriculture, urban settlement and dispute. The boundary along 2nd Street marks the division within the community and its sense of place. It also marks a challenge to rethink the parameters of economy, ecology and welfare and reconcile the disparities between them. Our assignment was simple. Redesign 2nd Street. But along the way we realized that Mountain View holds much more meaning and purpose. This neighborhood has the potential to face its challenges through innovative, elegant design and serve as an example of a beautiful reconciliation. …

Topological Dynamics Of Spike-Timing Dependent Plastic Neural Networks, David Stone Jan 2013

Topological Dynamics Of Spike-Timing Dependent Plastic Neural Networks, David Stone

Psychology ETDs

The effects of continual spike-timing dependent plasticity (STDP) on the topology of evolving neural networks were assessed. After a period of stabilization, a number of topological features were monitored periodically throughout simulations of network activity to quantify changes in network structure. Under a range of different input regimes and initial network configurations, each network maintained a robust and highly stable global structure. At the same time, a substantial set of small three-neuron subgraphs (triads) continued to undergo an array of changes and revealed a dynamic local topology. These findings suggest that on-going STDP provides an efficient means of selecting and …

Human Inspired Pattern Recognition Via Local Invariant Features, Dominic Ron Maestas Jan 2013

Human Inspired Pattern Recognition Via Local Invariant Features, Dominic Ron Maestas

Mechanical Engineering ETDs

Vision is increasingly becoming a vital element in the manufacturing industry. As complex as it already is, vision is becoming even more difficult to implement in a pattern recognition environment as it converges toward the level of what humans visualize. Relevant brain work technologies are allowing vision systems to add capability and tasks that were long reserved for humans. The ability to recognize patterns like humans do is a good goal in terms of performance metrics for manufacturing activities. To achieve this goal, we created a neural network that achieves pattern recognition analogous to the human visual cortex using high …

Biofilm Formation By Shewanella Oneidensis Mr-1 Towards Fundamental Understanding Of Anode Respiring Communities, Jared Roy Jan 2013

Biofilm Formation By Shewanella Oneidensis Mr-1 Towards Fundamental Understanding Of Anode Respiring Communities, Jared Roy

Nanoscience and Microsystems ETDs

Microbial fuel cells are bioelectrochemical devices where, on the anode, microorganisms oxidize complex carbon sources and reduce the electrode via complex mechanisms of extra-cellular electron transfer (EET). To date, Geobacter sulfurreducens has been identified as producing not only the largest current density but also large population density biofilms, of the known model organisms commonly used within the field. Another common model organism associated with microbial fuel cells is Shewanella oneidensis, containing multiple EET mechanisms and an apparent inability to form multi-layered biofilms in anaerobic culturing, i.e. microbial fuel cell operating conditions. In contrast to G. sulfurreducens, S. oneidensis biofilm formation …

Chemical and Biological Engineering ETDs

Polymer electrolyte membrane fuel cells are a promising alternative energy source, capable of being deployed as successful replacements in many stationary and mobile applications. These devices, however, lack durability, and this has become one of the limiting factors for commercialization. Many projects have focused on finding ways to improve their lifetimes, but few have tried to examine the underlying causes behind their corrosion. The goal of this project was to identify which parameters have a significant impact, both positive and negative, on PEMFC durability. To do this, three series of samples were analyzed using microscopic, spectroscopic, and electrochemical methods. Electron …

Are Graduate Students Rational? Macroeconomic Determinants Of Graduate Enrollment And Completions In The Biomedical Sciences, John Clack Jan 2013

Are Graduate Students Rational? Macroeconomic Determinants Of Graduate Enrollment And Completions In The Biomedical Sciences, John Clack

Economics ETDs

The National Institutes of Health (NIH) budget doubling from 1998 through 2003 stimulated demand for biomedical scientists, increasing both relative wages and employment. However, because research doctorates in these fields may take six years or more to complete, there is a substantial lag in the labor supply response to changing market conditions. Rational expectations models assume that prospective graduate students can forecast their expected future wages, taking into account other students likely responses and thus also future employment levels. However, prior research on student enrollment and degree completion in science and engineering fields suggests that market conditions at the time …

Transport Theoretical Studies Of Some Microscopic And Macroscopic Systems, Alden Astwood Jan 2013

Transport Theoretical Studies Of Some Microscopic And Macroscopic Systems, Alden Astwood

Physics & Astronomy ETDs

This dissertation is a report on theoretical transport studies of two systems of vastly different sizes. The first topic is electronic motion in quantum wires. In recent years, it has become possible to fabricate wires that are so small that quantum effects become important. The conduction properties of these wires are quite different than those of macroscopic wires. In this dissertation, we seek to understand scattering effects in quantum wires in a simple way. Some of the existing formalisms for studying transport in quantum wires are reviewed, and one such formalism is applied to calculate conductance in some simple systems. …

Nanomechanical Characterization Of Asphalt, Hasan Faisal Jan 2013

Nanomechanical Characterization Of Asphalt, Hasan Faisal

Civil Engineering ETDs

In this study, asphalt binder and asphalt concrete (AC) materials are characterized using laboratory nanoindentation testing and mechanical models. Traditionally, laboratory nanoindentation test data is analyzed using the Oliver-Pharr method to determine elastic modulus and hardness of materials. In a nanoindentation test, a test sample surface is indented or loaded by a hard indenter tip and then unloaded. In the past, several studies of the polymer materials area have selected a loading rate and dwell time (i.e., the peak load is kept constant for a few seconds before unloading) to avoid or minimize the viscous effect of a material. No …

Whither The World Polity? A Contribution To The Study Of International Organizations Through Survival Analysis Of Oecd Accession Rates, Kathryn Overton Jan 2013

Whither The World Polity? A Contribution To The Study Of International Organizations Through Survival Analysis Of Oecd Accession Rates, Kathryn Overton

Sociology ETDs

Accession to international governmental organizations (IGOs) has become an important corollary of modern international relations. Not only have IGOs proliferated significantly over the past fifty years, but, institutionalist paradigms, such as World Polity theory, suggest membership to such entities is inherent to the definition of modern statehood. Although IGO accession is rather commonplace, a full understanding of the motivation and gains associated with such commitments is not fully established. The current project contributes to this scholarly debate by applying World Polity theory to the question of why IGOs actively invite certain states into membership negotiations. The author employs a survival …

Biological And Biomimetic Oxygen Electro-Reduction By Enzymes, Shayna Brocato Jan 2013

Biological And Biomimetic Oxygen Electro-Reduction By Enzymes, Shayna Brocato

Chemical and Biological Engineering ETDs

Enzyme catalysts are a viable alternative to the traditional platinum based catalysts for the complete oxidation of complex fuels. Efficient oxidation of multi-carbon compounds, selective catalytic activity eliminating the need for fuel purification, and high performance under mild temperature and pH conditions make enzyme catalysts appealing for applications in vivo, implantable, and in vitro, portable energy sources. The full catalytic potential of enzymes can only be obtained if the full energy potential of a biofuel, complete oxidation to CO2, is obtained; this requires multiple reactions, i.e. multiple enzymes or an enzyme cascade. The efficiency of enzyme cascades improves with quaternary …
