Functional analysis to inform early design decisions for novel systems with substantial operations and maintenance costs

Creator:: Algarra, Nathan
Abstract:: Long field-life systems are those for which operational, as opposed to capital, expenditures dominate the life time cost of the system. In established product categories, operational experience and historical maintenance data allows engineers to make informed decisions influencing maintenance during the early design stages when design changes are at their...

Agile Bipedal Locomotion via Hierarchical Control by Incorporating Physical Principles, Learning, and Optimization

Creator:: Green, Kevin
Abstract:: Robotic Bipedal locomotion holds the potential for efficient, robust traversal of difficult terrain. The difficulty lies in the dynamics of locomotion which complicate control and motion planning. Bipedal locomotion dynamics are dimensionally large problems, extremely nonlinear, and operate on the limits of actuator capabilities, which limit the performance of generic...

Modeling Methods for Hydraulic Fracturing Wastewater Treatment Applications

Creator:: O'Hern, Hannah
Abstract:: Modeling of hydraulic fracturing wastewater treatment systems must be very accurate so it can be used for real-time modeling and control of the process. The treatment of hydraulic fracturing wastewater is complex because of the variability of the composition of hydraulic fracturing wastewater. In this work, literature review of hydraulic...

Fouling Characterization in Hypersaline Wastewater Treatment

Creator:: Messer, Morgan S.
Abstract:: Water supplies are diminishing worldwide and by 2025 two thirds of the population could be living in regions of water scarcity (local demand for water is greater than water supply). One method to increase available water sources is to use desalination technologies to separate water from saline solutions. While desalination...

Predicting Properties of Bio-jet Fuels using Machine Learning and ATR-FTIR Spectroscopy

Creator:: Mayer, Morgan A.
Abstract:: High-potential molecules derived from biomass sources may suitably replace or supplement traditional nonrenewable hydrocarbon fuels to reduce pollution and fuel processing costs. Due to expensive and time-consuming property testing, models that predict key properties from optical data would initially vet potential additives before investment and bench-scale testing. Attenuated Total Reflection...

Numerical and Analytical Evaluation of Residual Stresses in Deep Rolling

Creator:: Nelson, Dallas
Abstract:: Deep rolling is a surface finishing technique that is widely used in several industries, specifically aerospace and automotive. Extending fatigue life by inducing compressive residual stresses at and below the deep rolled surface has been the primary driving force behind this newfound popularity. Understanding the development of the residual stresses...

Design Optimization of a Structurally Flexible Wave Energy Converter with a Direct Search Algorithm

Creator:: Berrier, Austin S.
Abstract:: Several wave energy converter designs have been recently proposed that are made of flexible materials. Flexible devices are able to generate electricity by being stretched, and are intended to simplify deployment and maintenance concerns over existing wave energy devices. Due to the relative infancy of flexible wave energy converters, however,...

Pre-Prototyping Framework: An Early Design Prototyping Methodology for Human-Centered Products and Workplaces

Creator:: Ahmed, Salman
Abstract:: Prototyping is a crucial step in product design and development, but it is also known as the highest sunk cost. The top 20 Research and Development (R&D) department spends 142 billion dollars, yet 40 to 46 percent of this money goes into developing products that cannot even make to the...

Advanced Computational Modeling and Design of Wave Energy and Floating Offshore Wind Energy Technologies

Creator:: Mankle, Hannah L.
Abstract:: Given the immense energy potential of oshore wind and ocean waves, offshore renewable energy can significantly contribute to the renewable energy landscape. Fixed floating wind is already making strides internationally with increased electricity capacity, while floating offshore wind turbines and marine hydrokinetic (MHK) technology have significant potential that can...

Wave Energy From Idea, to Concept, to Converter: Structuring Methods for Design and Evaluation of Wave Energy Devices

Creator:: Trueworthy, Ali May
Abstract:: The amount of energy we use and the ways that we get that energy sit on the edge of dramatic change as the carbon budget which can keep the planet under 1.5C of global average temperature increase gets smaller (Allen, 2018). In response, we continue to research and develop renewable...
