The Effective Behavior of Thermoelectric Composites
Thermoelectric materials have attracted significant interests recently for their capability in converting heat directly into electricity and vice versa, and thus promise a wide range of energy and environmental applications. ... -
Effects of Advanced Modeling on High-Performance, Multi-Rotor Drone Dynamics and Energy Efficiency
This work focuses on using a dynamics-based approach to understand the effects of modeling choices on simulation of high-performance multi-rotor drones carrying heavy suspended payloads. Three aspects of the modeling and ... -
Effects of Fuel Composition on Combustion Stability and NOX Emissions for Traditional and Alternative Jet Fuels
Synthetic jet fuels are studied to help understand their viability as alternatives to traditionally derived jet fuel. Two combustion parameters - flame stability and NOX emissions - are used to compare these fuels through ... -
Effects of Temperature and Fuel Dilution on Soot Yields in an Inverted Gravity Flame Reactor
Inverted laminar co-flow diffusion flames varied by dilution and preheat are characterized by temperature and soot emission measurements. Flame conditions vary by fuel structure (ethane, ethylene, methane), fuel dilution ... -
Efficient Image Analysis for Low Quality Medical Images
Medical images captured with low-cost devices have some similar low quality characteristics such as a small field of view (FOV) compared to the overall size of the imaged area, low or degraded spatial resolution, and ... -
Electrohydrodynamic Actuators for Propulsion and Flow Control
Non-thermal plasma (NTP) actuators have been studied in the context of flow control, noise and drag reduction, lift augmentation, and laminar-turbulent transition control. These actuators have the advantages of simple ... -
Electrokinetic Locomotion
(2013-07-25)The past decade has seen the rapid development of synthetic particles capable of propelling themselves at the micro- and nanometer scale through aqueous media. Several groundbreaking experiments have shown these so-called ... -
Electromagnetic Thermoelectric Energy Harvesting Device
The International Energy Agency (IEA) reports 17.6% annual growth rate in sustainable energy production. However, sustainable power generation based on environmental conditions (wind, solar) requires an infrastructure that ... -
Electrowetting Liquid Lens Oscillations for Optical Applications
The ability to modulate the phase of a transmitted beam over space and time is valuable in optical systems. Adaptive optics systems, such as retina imaging systems, can require dynamic wavefront correction and shaping of ... -
Environmental Chamber to Regulate Film Morphology for Solar Energy Materials Printing Using Additive Manufacturing and Investigating the Role of Additives in Perovskites
Flexible ink solar cells are gaining increased interest from photovoltaic researchers and the rapid development in the field of additive manufacturing has made the fabrication of solution- processed hybrid organic-inorganic ... -
Environmental Noise from Underwater Explosions and the Impact of the Seabed on the Received Levels
In the following work measurements of underwater explosions from three experimental sites area presented and compared. The goals of this work are to present the measurements of small underwater explosions (charges weighing ... -
Estimation of Acoustic Particle Motion and Source Bearing Using a Drifting Hydrophone Array Near a River Current Turbine to Assess Disturbances to Fish
River hydrokinetic turbines may be an economical alternative to traditional energy sources for small communities on Alaskan rivers. However, there is concern that sound from these turbines could affect sockeye salmon ... -
Evaluating Embedded Heater Bonding for Composites
Out-of-autoclave bonding of high-strength carbon-fiber composites structures can reduce costs associated with autoclaves. Nevertheless, a concern is whether out-of-autoclave bonding results in a loss of delamination ... -
Evaluating multimodal biofeedback to target and improve motor control in cerebral palsy
Early gait rehabilitation is a critical priority for individuals with cerebral palsy (CP), as neurologic injury in development alters motor control and can lead to a series of progressive impairments which may limit ... -
Evaluation of Gait and Muscle Function with Ankle Foot Orthoses
Many individuals with cerebral palsy (CP) and stroke are prescribed ankle foot orthoses (AFOs) for use during daily life. AFOs have been shown to improve pathologic gait and walking speed in CP and stroke by providing ... -
Evaluation of muscle synergies in individuals with cerebral palsy
Cerebral palsy (CP) originates from a brain injury, causing impairments in motor control specific to the individual. These motor impairments manifest themselves differently between individuals, resulting in altered and ... -
Evaluation of the Mechanical Properties of Solid Oxide Fuel Cell Materials
In the pursuit of economic sources of “green energy”, Solid Oxide Fuel Cells (SOFCs) are of substantial interest due to their high efficiency, long-term stability, low emissions, and relatively low costs. With a capability ... -
EVAPORATION OF LIQUID DROPLETS ON FLAT AND CURVED SOLID SUBSTRATES
We study the evaporation of liquid droplets on flat and curved heated substrates. We derive an evolution equation for the drop thickness to evaluate its shape as it evaporates on a curved substrate. We adopt a one-sided ... -
Excitation Emission Matrix Fluorescence Spectroscopy based Sensing of Combustion Generated Particulate Matter
Human exposure to particulate matter (PM) is associated with adverse health effects, including cardiopulmonary diseases, neurological diseases, and lung cancer. PM can originate from mobile and industrial combustion sources, ... -
Excitation Emission Matrix Fluorescence Spectroscopy for analysis of Reactive Oxygen Species in Combustion Particulate Matter
The presence of particulate matter (PM) in the environment can lead to adverse health impacts, including respiratory, cardiovascular, neurological, and lung cancer. Air pollution has been estimated to cause 4.9 million ...
