Preston Manwaring and Dr. Mark Manwaring, Electrical and Computer Engineering Electro-anesthesia devices offer the ability to alleviate pain and maintain drug-induced anesthesia without re-administering drugs by passing a specially designed electrical current through the brain to sustain naturally or chemically produced endorphins. This potential extends the clinicians armementarium for pain management, drug-addiction rehabilitation, and general […]
Reproducible, Low-temperature Growth of Nanocrystals in an Amorphous Silicon Film
Spencer Kellis and Dr. Aaron Hawkins, Electrical and Computer Engineering During Plasma-Enhanced Chemical Vapor Deposition (PECVD) crystal growth, an electric field between two charged plates dissociates a gas into a cloud of positive and negative ions called a plasma. The silicon ions descend to the silicon wafer and bond to the surface. Temperature is controlled […]
Electromagnetic Properties of Water in the Presence of a Protein
Kelly Jeppesen and Professor Travis Oliphant, Electrical Engineering Light scattering is a means of detecting certain chemical properties of a sample of material. As a photon (light packet) encounters any material, there is some probability that the photon will be absorbed. The energy from an absorbed photon will either work to heat the sample or be reemitted. […]
Alignment of Metal Electrodes with Optical Fibers
Benjamin Ipson and Dr. Stephen Schultz, Electrical and Computer Engineering The field of fiber optics is becoming an increasingly important field to the world of communications. With increased use of optical fibers for communication comes the need for devices to use with the fibers. I have been working on the creation of an in-fiber electro-optic […]
Anisotropic Etching in Silicon and Other Materials Using a Reactive Ion Etcher
Justin Henrie and Dr. Aaron Hawkins, Electrical and Computer Engineering Microfabrication technology has been one of the major areas of advancement of technology from the latter half of the twentieth century until today. Initially, microfabrication wasn’t a new concept—it started as a way to make large, complex electronic circuits smaller, and therefore more durable and […]
Calibration of SeaWinds on ADEOS-II via the QuikSCAT Calibration Ground Station
Spencer Haycock and Dr. David G. Long, Electrical and Computer Engineering Introduction A scatterometer is essentially an orbiting radar aimed at the Earth’s surface. It can be used to study weather patterns, track icebergs, observe polar sea ice, detect climatic changes, and estimate environmental factors such as vegetation and soil moisture. Correct calibration of the […]
Co-validation of Jason-1 and QuikSCAT Wind Speeds Within the Context of TRMM Rain Data
Ryan Halterman and Dr. David Long, Electrical and Computer Engineering SeaWinds on QuikSCAT is a satellite-based scatterometer designed to measure near-surface winds over the earth’s oceans. Ocean surface wind speed is an important parameter in many short-term and long-term climate and weather analyses. QuikSCAT is a rapidly developed replacement for the successful, although prematurely terminated, […]
Multi-Agent Communication Framework
Ryan R. Falke and Dr. James Archibald, Electrical and Computer Engineering Multi-agent systems consisting of large numbers of autonomous robots are ideal candidates for tasks that could threaten human lives. However, the complexity and quantity of work required for precise coordination within such systems can be considerable. Our team developed a powerful but lightweight communication […]
Construction of an On-chip Microfluidic Pumping System
Ghassan Sanber and Dr. Aaron Hawkins, Electrical and Computer Engineering The fabrication and testing of micro-scale electroosmotic pumps, made with a thin-film deposition process compatible with standard silicon processing, is described. The fabrication method relies on chemical vapor deposition and chemical sacrificial etching to form long hollow fluid microchannels. Each pump consists of parallel narrow […]
Integrated Optics – Coupling and Guiding
Josh Kvavle and Dr. Aaron Hawkins, Electrical and Computer Engineering The computer has changed every aspect of the modern world. It almost seems that this burst of technological advance in computers will continue without limit. One can go and buy a computer with more “gigahertz” today for less that another bought one for the week […]
