Meta-Network Analysis Of Complex Construction Systems: Improving Project Efficiency Using Novel Computer-Based Analytic Methodology, Ethan Cummiskey

Honors Scholar Theses

The objective of this study is to build upon the framework of a meta-network approach to assessing vulnerabilities in construction projects. By viewing these complex environments as configurations of various nodes and links, it is possible to show the relationship between each entity in the project and the overall completion that is achieved from these connections. To expand upon previous studies, the vulnerabilities measured from this approach will be used to optimize the current network to eliminate any shortcoming in the project model. By investigating the congruence of different agents on the project, resources and informational nodes can be supplied …

An Assessment Of Renewable Energy Technology Implementation In Storrs, Connecticut: Emissions Reduction And Feasibility Of A Microgrid System At Uconn, Sophie Macdonald

Honors Scholar Theses

The purpose of this project is to design a clean energy-sourced microgrid for UConn’s main campus that would reduce the university’s energy emissions while remaining within the geographic boundaries of viable UConn-owned land. Economic cost was not considered in this analysis; instead, emissions and space constraints were the optimized measures of value and feasibility. Sources of energy that were considered include photovoltaics (PV), wind turbines, hydrokinetic systems, and fuel cells. Energy storage capacity was included in the analysis as well. The overall system was optimized first by ignoring space constraints and for a minimum of 10% reduction from the current …

Promoting The Sustainable Utilization Of Groundwater Resources In Ethiopia Using The Integrated Groundwater Footprint Index, Xinyu Lin

Honors Scholar Theses

The country of Ethiopia is highly vulnerable to human-caused climate change and is already suffering from the effects. The predominately rural population relies heavily on small-scale agriculture, with 78% of households having at least one member engaged in the field, yet staple crops are highly susceptible to droughts and other weather shocks. Total and agricultural GDP growth in the country have been strongly linked to inter-annual rainfall variability, of which Ethiopia has among the highest in sub-Saharan Africa. A decrease in rainfall since the 1970s has been one of the primary causes of low crop yields, and stresses the immediate …

Mechanism Of Insulin Aggregation: Applied To Alzheimer's Disease, Milos Atz

Honors Scholar Theses

Alzheimer’s disease, a debilitating neurodegenerative illness, is caused by the irreversible aggregation of beta-amyloid proteins in the brain. In Alzheimer’s brains, the protein can become disfigured, causing it to aggregate into long, insoluble fibers that deposit on brain tissue. Studying the aggregation mechanisms of amyloid proteins can lead to a deeper understanding of the progression of Alzheimer’s disease and possibly point towards a potential cure or treatment for the disease. Heat induced aggregation of insulin provides a model system to study the aggregation of amyloidogenic proteins. This study investigates the early stages of heat induced insulin aggregation using dynamic light …

Optimizing Polymer Fluorescence For Explosives Detection, Rose K. Cersonsky

Honors Scholar Theses

Pyrene is commonly used for explosives detection, as when mixed with polystyrene, the fluorescence intensity of the resulting film can be used as an indicator of the presence of nitro-aromatic, nitro-ether, or nitro-amine explosives. Previous studieshave tested a three-component system including pyrene, polystyrene, and a salt, tetrabutylammonium hexafluorophosphate (TBAHP). From these previous studies, it has been seen that vapor pressure of the preparation area is a governing factor in the formation of excimers, which are instrumental in achieving and maintaining fluorescence intensity. In this study, three parameters – solution concentration, film thickness, and molecular weight of polystyrene are examined to …

Improved Tissue Caliper, Kenneth Ted-Luck Hung

Honors Scholar Theses

My honors thesis will be covering the work that I am doing for my senior design project. My senior design project involves building a tissue caliper for medical device company, Covidien. During medical research and development it is often necessary to measure and document the thickness of tissue samples and media (simulated tissue foam). A device known as a tissue caliper is currently used to perform such measurements. Our project requires us to design, build, calibrate, and validate an instrument, which will be capable of measuring sample thicknesses ranging from 0.10 to 1.00 inches with an accuracy of ± 0.005 …

Eurotech Students In Germany: Preparation, Experience And Outcome, Daisy A. Michaels

Master's Theses

Higher education study abroad programs for U.S. students are on the rise. A variety of undergraduate disciplines are being coupled with international components to bring U.S. students to a higher level of global awareness to meet the demands of today’s economy. The University of Connecticut’s Eurotech Program is an example of this trend. Its students earn degrees in both German and engineering in a five year program. They are given practical training through study and internships in Germany under the auspices of the Baden-Württemberg Exchange Program. One of the Eurotech Program’s major goals is to enhance job opportunities for its …

Automation Of Orthodontic Wire Tester For Performing Three Point Bending Tests, Adithya Venkatesan

Master's Theses

Abstract

Understanding the biomechanical factors in orthodontics is important in order to improve the overall effectiveness of actual clinical treatment. An accurate method to study the threedimensional (3D) force systems and the resulting movements of teeth during orthodontic treatment is needed along with the understanding of the material properties of any orthodontic wire. Until recently, most of the orthodontic biomechanics literature was limited to twodimensional experimental studies. Recent advances in threedimensional computer modeling have also been developed but have been limited to the manual control of tooth movement. Overall, there is very little published evidence in the literature on the …
