Aaron Harrison and Dr. Vincent Wilding, Department of Chemical Engineering The Uros Islands in Peru, also known as the floating islands on Lake Titicaca, are made from reeds by the inhabitants. These reeds serve not only as shelter, but also as the main cooking fuel for nine months of the year. During the other three […]
Stand-Alone Lance for Nanoinjection of DNA
Mark Fernelius and Dr. Larry Howell, Department of Mechanical Engineering Technologies for injecting DNA into egg cells have greatly facilitated genetic research. Microinjection is a current standard for this purpose. It uses a hollow glass needle to inject a solution containing DNA into cells. Although widely used, microinjection has several significant challenges. First, the DNA […]
An Improved Estimation of Passive Wrist Stiffness Using Various Techniques
Will Drake and Dr. Steven Charles, Department of Mechanical Engineering The wrist plays a vital yet frequently overlooked role in positioning and supporting the hand during activities of daily living. Particularly during low-level activities (such as typing), passive joint stiffness dominates wrist dynamics and constitutes the main obstacle to motion. In spite of its importance, […]
Combustion-Driven Water Heating in Huatta, Peru: A Solution for Third-World Countries
Brandon Decker and Dr. Matt Jones, Department of Mechanical Engineering This group aimed to construct a system that heated water to at least 38°C (100 OF) – warm enough for bathing, dish washing, and washing hands. Our goal was to create a system inexpensive and simple enough for implementation in Huatta, Peru. We also aimed […]
Modular Containerized Provisional Habitations for Emergency Disaster Relief
Matthew Butler and Professor Brian Capt, School of Technology Perhaps the greatest challenge to this project was determining which materials to use in the construction of the modules. There are a multitude of materials that could have been used for the project, many of which might have worked well for the designated use. The shelters have […]
Tapered Photoresist in the Manufacture of Nanosieves
Meagan Bracken and Dr. Aaron Hawkins, Department of Electrical and Computer Engineering The purpose of this project was to assist in the manufacturing of nanosieves. The device is designed to separates nano-size particles from the fluid substance in which they are contained. An example of this, and one of the main targets of this project, is the […]
Waste Treatment for the Uros Islands
Spencer Bowen and Dr. Randy Lewis, Department of Chemical Engineering The goal of this project was to design and install one bio-toilet system before the end of May 2011 in cooperation with the inhabitants of the Uros Islands on Lake Titicaca, Peru. The system is composed of two parts: the bio-toilet infrastructure and the treatment […]
Forked Shaped Rebound Droplet for Impingement on Anisotropic Superhydrophobic Surfaces
David Bilodeau and Dr. Daniel Maynes, Department of Mechanical Engineering Background Many metals rust when exposed to moisture and that rusting can cause the item that is made of that metal to break down. A superhydrophobic surface can repel liquids and keep metals from rusting longer. Superhydrophobic surfaces have existed in nature for a long […]
Measurement of Steel Corrosion in Bridge Decks by Impedance Spectroscopy
Paul Bartholomew and Dr. Brian Mazzeo, Department of Electrical and Computer Engineering On bridge decks, a specified thickness of concrete cover, usually between 2.0 and 3.0 in., is provided over the embedded reinforcing steel as a protective layer. When chloride ions penetrate the concrete cover, corrosion of the reinforcement can occur [1, 2, 3]. Corrosion […]
Brain Electrophysiological Source Localization of MMN & P300 Response in Auditory Processing
Amy Ragsdale and Dr. David McPherson, Department of Communication Disorders Source localization is a tool used to identify a precise visual location within the brain which allows for interpretation of the source of the brain activity. In this research, source localization is used to provide a more accurate identification and evaluation of the neurophysiological sources that contribute to […]
