Hindfoot Kinematics of Healthy Subjects Using Lateral Wedge Insoles in a Biplane Fluoroscopy System
Lateral wedge insoles (LWIs) are a type of orthosis used to reduce the external knee adduction moment (EKAM), which is associated with the development and progression of tibiofemoral osteoarthritis. However, their effect ... -
Holistic Modeling, Design & Analysis of Integrated Stirling and Auxiliary Clean Energy Systems for Combined Heat and Power Applications
The research revolves around the development of a model to design and analyze Stirling systems. Lack of a standard approach to study Stirling systems and difficulty in generalizing existing approaches pose stiff challenges. ... -
Hybrid Vehicle Supervisory Controller Development Process to Minimize Emissions and Fuel Consumption in EcoCAR 2
This thesis presents the design process used to create and validate a hybrid vehicle supervisory control system for a plug-in hybrid electric vehicle in the EcoCAR 2 competition. The vehicle utilized a Parallel through the ... -
Hypoxic Intrusions to Puget Sound from the Pacific Ocean
(2014-04-30)Oceanic intrusions of dense, hypoxic water regularly occur at the entrance to Puget Sound, WA (USA), and may be significant to regional dissolved oxygen levels. Seabed observations at Admiralty Inlet from 2009 to 2013 show ... -
Image Fusion for Misaligned Visual and Thermal Images
The main challenge of a Wilderness Search and Rescue (WiSAR) mission is tocover a large area within a reasonable and short amount of time effectively. The recent development in the area of sensor-equipped Unmanned Aerial ... -
Implications of Biofouling on Cross-flow Turbine Performance
While biofouling is known to degrade the performance of marine energy conversion systems, prior experimental work has not explored this topic for cross-flow turbines. Here, we present experiments that investigate the impact ... -
Improving the Accuracy of 3-D Reconstruction in Robotic Vision Applications
Three-dimensional (3D) surface reconstruction is a process for retrieving the 3D shape and appearance of real objects or scenes. The generated 3D point clouds can be used in many fields, including entertainment, measurement, ... -
Improving the Manufacturability of Active Microfluidic Devices using Stereolithography (SL)
Microfluidic devices are instrumental in a variety of scientific and biomedical applications. These devices have revolutionized scientific research in areas ranging from cancer diagnostics to drug discovery and neuroscience. ... -
Improving Wearable Devices for Virtual Reality using Soft Robotics
With the ever growing popularity of wearable devices, virtual reality and augmented reality, human-computer integration is not far from our reach. Wearable devices are meant to be worn as an extension of the human body. ... -
In Silico Techniques to Improve Understanding of Gait in Cerebral Palsy
In this dissertation we focus on utilizing computer-aided engineering techniques to improve our understanding of gait in cerebral palsy (CP). CP is the most common motor disability in children and arises from a non-progressive ... -
In-vitro Clot Formation and Failure
A primary cause of bleeding and mortality after traumatic injury is failure of hemostatic clot formation at wound sites. After trauma, approximately 25-30% of severe injured patients display trauma induced coagulopathy ... -
Individually-controllable magnetic artificial cilia for microfluidic manipulation tasks
This thesis presents the design, modeling, and control of a magnetic artificial cilia system in which the cilia are individually controllable. In nature, cilia exhibit metachronal waves, or a phase difference between ... -
Inferring human intent in novice human-in-the-loop control tasks
Inferring intentions is fundamental to successful interaction among two or more agents. For example, in learning from a teacher the student must be able to first understand the teacher’s intent from the displayed demonstrations ... -
The Influence of Materials and Fabrication Techniques on Dye-sensitized Solar Cell Performance
(2013-04-17)The performance of dye-sensitized solar cells (DSC) as reported in the literature varies even when the materials and/or methods cited are essentially the same. DSC performance even varies significantly within a single lab ... -
Instrumented Footwear to Measure Plantar Tissue Properties
The prevalence of diabetes is increasing in the United States, and the lack of a cure makes it imperative to manage symptoms to prevent overall health from worsening. Diabetes-related foot complications include peripheral ... -
Integrating natural and synthetic systems for airborne bio-hybrid chemical sensing devices
Chemical sensing is a universal capability of living organisms across all scales and taxa. Most animals depend on this ability for their survival and flying animals have evolved sophisticated sensing capabilities and ... -
Intermittent turbulence in the very stable Ekman layer
(2000)This study describes a Direct Numerical Simulation (DNS) of a very stable Ekman layer in which a constant downward heat flux is applied at the lower boundary, thus cooling the fluid above. Numerical experiments were performed ... -
Investigation of biomarker-targeted SERS nanoparticles for multiplexed molecular imaging of fresh tissue specimens
Biomarker-targeted surface-enhanced Raman scattering (SERS) nanoparticles (NPs) have been explored as a viable option for targeting and imaging multiple cell-surface protein biomarkers of cancer. A previously-developed ... -
An Investigation of Lean Blowout of Gaseous Fuel Alternatives to Natural Gas
