Jared Keeley and Dr. Aaron Hawkins, Electrial and Computer Engineering Main Text In the field of micro-electromechanical systems (MEMS) and micro-opto-electromechanical systems (MOEMS) fabrication, photoresists are used to form 3D structures on a scale of micro- or even nanometers. This is necessary to create the microelectronics used in many devices. One structure that photoresist can […]
Post-Translational Modification in Cell-Free Protein Synthesis
Anna Katz and Dr. Brad Bundy, Chemical Engineering Introduction The purpose of this project was to examine the phenomenon of eukaryotic myristoylation in a prokaryotic cell-free environment. Basically the idea is that eukaryotic cells such as those within humans have a more robust system for synthesizing protein but it is cheaper, faster, and more easily […]
Piezoresistivity in Nickel Nanostrand Composite Materials as Studied by Three-Dimensional Reconstruction on Focused Ion Beam Serial-Sections
Oliver Johnson and Dr. David Fullwood, Mechanical Engineering Main Text The development of a large-strain sensor technology will open doors for improved engineering design and scientific research in many fields. Such a technology would allow for advances in biomechanical engineering, e.g., prosthetic limb and artificial organ design. Additionally this kind of sensor technology could be […]
Effect of Variability in Concrete Cover on Concrete Bridge Deck Service Life
Jeffrey Hoki and Dr. W. Spencer Guthrie, Civil and Environmental Engineering Before reliable data could be gathered, proper procedures for using a covermeter needed to be established. The American Society for Testing and Materials (ASTM) does not currently have a standard for testing rebar cover depth by means of an electromagnetic covermeter. Therefore, the only […]
Thermal Protection For Extreme Labor
Christopher Hanks and Professor Dave Morgan, Industrial Design Many people died when temperatures rose to 115°F in Southeastern Europe in July of 2000(Blumberg). The Sahara Desert exceeds 120°F, creating a nearly inhospitable environment. The temperature off of the Phoenix Airport runway was reported at 150°F the summer of 2009. This very same environment is the workplace […]
Autonomous Soaring Using Real-Time Wind Estimation
Mark J. Cutler and Dr. Timothy McLain, Department of Mechanical Engineering Small unmanned aerial vehicles (UAVs) are obtaining increasing utilization in many applications. Their small size (0.5-4m wingspan) allows them to fly close to the ground, providing useful observation and tracking data. This small size, however, comes at the expense of flight time. As UAV […]
Critical Component Selection for Implementing Barriers to Reverse Engineering
Shane K. Curtis and Dr. Christopher Mattson, Mechanical Engineering Main Text Reverse engineering is a prominent design strategy in industry, employed by many to uncover the enabling technologies of innovative products. Unfortunately, there is little motivation for original designers to create new products if competitors can reverse engineer these products and reproduce them at a […]
Economic and Environmental Justification of a Thermoelectric Waste Heat Recovery System
John Christiansen and Dr. Matthew Jones, Mechanical Engineering Department Introduction In recent years, the concepts of energy, energy production, effects of energy consumption on the environment, and sustainable development have become increasingly significant as members of society become more aware of their level of energy consumption. However, in energy production for home, commercial, or industrial […]
High-Speed Full-Spectrum Interrogation of Fiber Bragg Gratings for Composite Impact Sensing
Spencer Chadderdon and Dr. Richard Selfridge, Electrical and Computer Engineering Fiber Bragg gratings (FBG) sensors are useful for static and dynamic event monitoring which make then suitable for a wide variety of applications. Dynamic interrogation of FBG sensors has primarily been performed using peak-tracking methods that have repetition rates approaching the megahertz range. However, tracking […]
Dynamic Loading on Horizontal Axis Wind Turbine Blades
Christopher Brinkerhoff and Professor Julie Vanderhoff, Mechanical Engineering Introduction Currently, there is much interest involving technologies dealing with clean and renewable energy sources. The current goal in the United States is to produce 20% of its electrical needs by wind power by the year 2030. Wind energy is seen as a viable option for further research […]
