Leticia Adams and Dr. Eliza Tanner, Communications Over the past ten years, Chilean media have had more access to international media due to Chile’s expanding telecommunications platform. The purpose of this study was to investigate whether or not international media coverage of human rights (HR) issues influences Chilean media coverage of HR issues. I define […]
Stereogram Printer
Daniel E. Smalley and Dr. Richard H. Selfridge, Electrical and Computer Engineering The goal of this creative works project was to build an inexpensive Stereogram printer capable of producing three-dimensional images from a series of two-dimensional pictures. This type of printer is very useful for making hologram-like images of objects and scenes that would be […]
A Compliant Orthoplanar Piezoelectric Actuator
Aaron Shelley and Dr. Larry Howell, Mechanical Engineering This research focused on developing a new actuator/motor by integrating two previously unrelated technologies. In the past, piezoelectric crystals have been used primarily to measure acceleration in the engineering field, because of their unique nature of generating electricity when changes in their position occur. Modern researchers now […]
Low-Frequency Ultrasound Increases Outer Membrane Permeability of Pseudomonas aeruginosa and Escherichia coli
Christopher M. Runyan and Dr. William G. Pitt, Chemical Engineering Introduction Our lab has investigated the use of low-frequency ultrasound as an adjuvant to antibacterial therapy. We have found that ultrasound can increase killing of certain combinations of antibiotics with bacteria. Ultrasound at very low frequencies, alone, may kill bacteria; however, these frequencies are harmful […]
Real-time Adaptive Cancellation of non-Stationary Interference in Radio Astronomy
Andrew Poulsen and Dr. Brian Jeffs, Electrical and Computer Engineering When images of remote galaxies/stars are observed by radio telescope, much sensitivity can be blurred by interference. This interference can be caused by both the atmosphere and man-made sources. Specifically, the Russian GLONASS satellite system transmits data at a bandwidth wherein much information important to […]
Unity IV: Fuselage Body Design, Analysis, Testing, and Construction
Alexis J. Pabst and Dr. Paul Eastman, Mechanical Engineering Introduction The Unity IV rocket is a twenty-foot tall rocket with a 16.5-inch diameter. It is a super-sonic, hybrid rocket that uses a solid propellant and liquid oxidizer. The rocket has been designed and built by students from three Utah universities. It is intended to take […]
Development of Instruments for the Diagnosis and Treatment of Hydrocephalus
Ryan T. Ochsner and Dr. Mark Manwaring, Electrical and Computer Engineering The Brain Instrumentation Laboratory (1220 SWKT) associated with the Department of Neuroscience and Electrical and Computer Engineering at Brigham Young University specializes in the development of new technologies which may facilitate the management of diseases of the brain. Of specific interest to the laboratory […]
Development of Stable Silica Washcoats for Monolithic Substrates
Ethan A. Mastny and Dr. Calvin H. Bartholomew, Chemical Engineering The objective was to develop an efficient procedure for depositing silica washcoats onto cellular, ceramic monoliths while ensuring that the silica maintains its desired properties of surface area and pore structure and is stable against erosion. Catalyst coated ceramic monoliths find application in automotive emissions […]
Use of Linear Analysis of Microstructures in Defining Performance Closures for Highly Constrained Mechanical Design
Mark Lyon and Dr. Brent L. Adams, Mechanical Engineering Using methods described by Adams1, the design of a compliant beam was modeled in a multidimensional Fourier design space. A compliant beam is one that achieves motion through bending. The motivation for the problem was a bicycle derailleur. A compliant beam could replace the entire rear […]
A New Stereology
Ryan J. Larsen and Dr. Brent L. Adams, Mechanical Engineering Much research in recent years has focused on producing polycrystalline materials with high numbers of special grain boundaries. Special grain boundaries are defined as boundaries with desirable properties, such as resistance to corrosion, cracking, or precipitation. Most researchers describe grain boundary geometry only with the […]
