3D-printed Microfluidic Control Systems
Microfluidic devices are tools for manipulating fluids in microchannels to achieve a variety of functions, for instance, sample mixing, analytes testing and detection, dispensing, etc. These functions provided by microfluidic ... -
A Biomechanically and Anatomically Realistic Foot Model (BAREFOOT)
Traditionally, investigators utilize human studies, cadaver studies, and finite element model studies to conduct lower limb biomechanical research. In other realms of biomechanics, a fourth alternative has been recently ... -
A Coronally-Clutching Ankle to Improve Amputee Balance on Coronally-Uneven and Unpredictable Terrain
To improve amputee balance on coronally-uneven and unpredictable terrain, a coronally-clutching ankle (CCA) prosthesis was developed and tested using amputee participants. In its adapting mode, the CCA device enabled free ... -
A Custom Fabricated Low Weight On-Board Vision Sensor for Insect Scale Robot
Controlled flight of insect scale ( 100 mg) Micro Aerial Vehicles (MAVs) has to date required offboard sensors and computation. Achieving autonomy in more general environment will require integrating sensors such as a ... -
A GPU Accelerated Signed Distance Voxel Modeling System
This dissertation presents the capability of GPU-based parallel computing to support inter- active editing of solids represented by interpolated grids of signed distance values. The basic format of values on a grid is ... -
A Heuristic Optimization Approach to Hydrodynamic Wave Energy Converter Geometry
Ocean waves are an abundant global resource that can be converted to mechanical and electrical power. Modern research on wave energy conversion began in the 1970s, with many types of wave energy converter designs under ... -
A Learning Approach for Extending Human-Robot Collaboration to Manufacturing-Specific Tasks
This thesis presents the development and evaluation of methods for extending shared autonomy to limited-access manufacturing telerobotics. Shared teleoperation has potential to reduce strenuous working conditions and ... -
A Novel Walking Cane with Haptic Biofeedback Reduces Degenerative Loading in the Arthritic Knee
Knee osteoarthritis is the most common joint disorder and a leading cause of ambulatory disability in adults. Conservative treatments of osteoarthritis are lacking and the most commonly prescribed mobility aid, the walking ... -
A Passive Pediatric Exoskeleton to Improve the Walking Ability of Children with Neuromuscular Disorders
Children with neuromuscular disorders, such as cerebral palsy (CP) often have walking limitations. Assistive devices for home use, such as walkers and crutches, may not provide optimal participation opportunities or lead ... -
A Quasi-Passive Biarticular Prosthesis and Novel Musculoskeletal Model for Transtibial Amputees
University of Washington Abstract A Quasi-Passive Biarticular Prosthesis and Novel Musculoskeletal Model for Transtibial Amputees Andrea Willson Chair of the Supervisory Committee: Patrick Aubin, Ph.D. Affiliate Assistant ... -
A Study of Machining Effects on the Surface Integrity, Strength Properties, Damage Evolution and Fatigue Strength of Composite Laminates
A Study of Machining Effects on the Surface Integrity, Strength Properties, Damage Evolution and Fatigue Strength of Composite Laminates Harinder Singh Oberoi Chair of the Supervisory Committee: Dr. Ramulu Mamidala Department ... -
A study on the fracturing behavior and scaling of carbon/glass hybrid composites
One of the factors hindering the broad application of composites is their relative brittleness leading to sudden failure with no significant damage precursors. This makes designing with composites very challenging and ... -
A Vehicle Dynamics Model for Torque Vectoring During a Turn.
The focus of this research work is to develop a comprehensive vehicle dynamics model which addresses the coupling between longitudinal, lateral and vertical dynamics. Besides providing information about the translational ... -
Abrasive Waterjet Contour Cutting of Thick Titanium/Graphite Laminates
One of the primary focus in aerospace industry is the reduction of buy-to-fly ratio. Although TiGr laminates are molded/autoclaved to a near net shape, secondary machining such as drilling, peripheral machining and contouring ... -
Advanced Environmental Monitoring for Marine Renewable Energy
Marine renewable energy has the potential to provide clean, reliable power to coastal communities and offshore facilities. However, the effects that marine energy development might have on the environment are not yet well ... -
Advanced Methods to Produce and Characterize Transport Properties of Novel Nanoporous Polymers
In this work, experimental techniques, equipment, apparatuses, models, algorithms, and software codes were developed to explore the nanoporous structure of polyetherimide (PEI) created using the solid-state foaming process. ... -
Advancements in Optical Properties of Thermochromic VO2 Films through Experimental and Numerical Investigations
The Department of Energy reports that buildings consume more than 40% of primary energy in the U.S. and that this trend will continue for the foreseeable future. Furthermore, windows constitute a major path for energy ... -
Advancements in Process Development and Mechanical Properties of Recycled Glass Building Materials Through Experimentation and Analytical Modeling
Over the past 50 years U.S. consumers and municipalities have made efforts to decrease landfill waste and reduce raw material extraction through recycling. The rate of recycling has risen tenfold over that time period and ... -
Advancing Marine Renewable Energy Monitoring Capabilities
Marine renewable energy is poised to contribute substantially to electricity generation over the coming decades. Marine resources are abundant, but generation options must harness these resources in an economically-competitive ... -
Aerodynamic Removal and Characterization of Particulate Trace Residues on Model Surfaces
Trace residues of illicit substances and biological contamination of the surfaces remain accessible for long times because of their volatility. Although the non-contact surface sampling has been demonstrated using ...
