Recycling of Carbon Fiber Reinforced Polymers in Subcritical Water with Acetic Acid Amendment
A novel single-stage solvolysis process is proposed for recycling carbon fibers from an unknown epoxy-based composite material using 50 wt % acetic acid under subcritical conditions. The process yields 100 % recovery ... -
Reduced Deformation Transport of Flexible Objects using Decentralized Robot Networks
This dissertation presents and evaluates new control approaches for flexible object transport using robot networks. Recent works have investigated bio-inspired strategies to transport objects using decentralized robot ... -
Reducing Socket Discomfort and Torsional Stresses for Individuals With Lower-Limb Amputation Using a Novel Prosthesis
Individuals with lower-limb amputation often suffer pain and discomfort at the socket-residual limb interface after using their prosthesis. A portion of this pain and discomfort can be isolated to the transverse plane. It ... -
Remote Visualization and Detection of Foreign Object Debris in Aerospace Manufacturing using a Low-Cost Depth Camera
Performing work within limited access environments such as aircraft wings is ergonomically hazardous. Often, mechanics are required to crawl through a waist-sized access hole to perform work in a wing. Within these spaces, ... -
Research on the Static Response Mechanism of Event Cameras and Their Applications in Static Scenes
Event cameras are novel sensors that have gained significant importance in the field of dynamic vision since the first prototype in 2008. Unlike conventional frame-based cameras, event cameras exhibit independent and ... -
Resistive Embedded Heating for Homogeneous Curing of Composite Damage Repair
The increased use of composite materials in passenger aircrafts has resulted in an escalation of maintenance issues associated with composite structure damage from a variety of causes including impacts during towing, bird ... -
Resolving Spatial Resource Gradients at Tidal Energy Sites
(2012-08-10)Station-keeping, a vessel-based spatial surveying method for resolving details of the hydrokinetic resource, is presented in the context of the general methodology and also for the specific case of a survey conducted in ... -
Rheology and Microfluidic flows of a cationic surfactant and hydrotropic salt mixture
The widespread use of wormlike micellar solutions is commonly found in household items such as cosmetic products, industrial fluids used in enhanced oil recovery and as drag reducing agents, and in biological applications ... -
RoboFly: Towards Autonomous Flight of a Multimodal Insect-Scale Robot
Insect-sized robots have numerous applications due to their small size. For example, they can go into confined spaces where humans or larger robots cannot. These applications include gas leak detections in pipelines, search ... -
Robotic Target Following Under Dynamic and Collaborative Vision Feedback
Following rapidly and precisely a moving target has become the core functionality in robotic systems for transportation, manufacturing, and surgery. Among existing target following methods, vision-based tracking continues ... -
Robust Sparse Identification and Saddle Mediated Transport of Nonlinear Dynamics
The data-driven modeling approach has become increasingly popular to model the system where the first-principled approach is prohibitively challenging, such as finance, climate science, biology, epidemiology, etc. The ... -
Role of NNH in Low-NOx Hydrogen Combustion
The role of the NNH mechanism in NOx formation is investigated using a jet stirred reactor (JSR). Two sets of experiments are performed over a wide range of fuel-air equivalence ratios (0.8-1.3) for combustion of hydrogen. ... -
Rule based behavior classification via accelerometry in transtibial amputees
A high-performing and comfortable prosthesis follows from an understanding of how amputee activity modulates residual limb volume and socket fit. There are currently very few systems available which capture general long-term ... -
SAE Level 2 ADAS - Controller Design for UW EcoCAR
This work focuses on building a supervisory controller for the UW EcoCAR to incorporate SAE level 2 autonomy features. It comprises Adaptive Cruise Control (ACC), Automatic Emergency Braking (AEB) and Steering Assistance. ... -
Sample Preparation for Point-of-Care Nucleic Acid Amplification Testing of Bloodborne Viruses
Nucleic acid amplification tests (NAATs) provide high diagnostic accuracy for infectious diseases and quantitative results for monitoring viral infections. The majority of NAATs require complex equipment, cold chain dependent ... -
Scaling Effects on the Hydrodynamics and Performance of Current Turbines
The performance of a current turbine is influenced by numerous variables related to the geometry of the turbine and channel, the fluid properties, and the external forces acting on the system. These variables can be ... -
Scaling of Point-Absorber Wave Energy Converter Hydrodynamics
Wave energy converters (WECs) are devices that generate mechanical or electrical power from the motion of ocean waves. Point absorber WECs react to the motion of the ocean waves at or near the surface, and have a characteristic ... -
Screening Tests of Composites for Use in Tidal Energy Devices
(2011-06-09)Four different composite material systems are subjected to nine months of in situ exposure at a potential tidal energy site. These four systems are fiberglass/epoxy, carbon fiber/epoxy, fiberglass/vinylester, and carbon ... -
Sensing and Actuating with Fringing Electric Field
(2013-04-17)Many researchers worldwide have used the fringing electric field (FEF) to develop different devices and technologies to fulfill industrial requirements. In some cases, simple analytical models fulfill development requirements, ... -
Sensory Feedback in Lower Limb Prostheses
Does the loss of limb necessarily entail the loss of sensation that limb provided? We argue that it does not. Targeted Reinnervation surgery provides a way to restore native feelings of sensation: it is an increasingly ...
