Dru Bailey and Professor Robert Barrett, Illustration When I began the process of applying for this grant, my idea was to go to Haiti and serve the children there. However, after I had received the ORCA grant, I discovered that groups were no longer allowed into the country due to safety issues during the elections in […]
DS3 Web Interface
Kevin Wong and Dr. Gordon Romney, Information Technology As digital media storage is growing ever more popular, security of this data is becoming more and more important. Intruders can relatively easily alter digital files and documents. Several customers, such as the Harold B. Lee Library, the archivist of the Dead Sea Scrolls, and the Director […]
Stress-Induced Development of Human Vocal Fold Morphology
Kendall Teichert and Dr. Scott Thomson, Mechanical Engineering Introduction Ramig and Verdolini state: “it has been estimated that 3% to 9% of the total population in the United States has a voice disorder.” One way to better understand voice disorders is to learn about the development of the structures and properties, or morphology, they affect. […]
Tumor Drug Concentration Due to Ultrasonic Drug Delivery
Bryant Staples and Dr. William Pitt, Chemical Engineering The tri-block copolymer, Pluronic P105, has been found to be an ideal ultrasonically activated drug delivery vehicle because it forms micelles with hydrophobic polypropylene oxide cores that sequester hydrophobic drugs (Fig. 1). These micelles release their contents upon the application of low frequency ultrasound [1] such that […]
Unnecessary Compaction Effort Due to the 95% Fixation
Aaron B. Smith and Dr. Travis Gerber, Civil and Environmental Engineering Introduction When soils are compacted, they become stronger and experience less settlement. Because of these improved characteristics, soils are usually compacted to some specified level before a foundation is built on top of them. The difficulty encountered is how to determine what the specified […]
Charpy Impact Study of Friction Stir Welded X-65 Steel
David Segrera and Dr. Tracy Nelson, Mechanical Engineering Industrial need for a high-strength, ferritic steel exhibiting desirable weldability, malleability, and corrosion resistance properties has led to the development of high strength, low alloy (HSLA) X-65 Steel. This class of steel uses small amounts of alloying material and very little carbon to make it more corrosion […]
Digital Signature Signing Server Project Management and Client Support
Frederick Penrose and Dr. Gordon Romney, Information Technology Proposal With the ever increasing move to electronic documents in every industry and field, digital security is becoming a greater concern for everyone. Various departments within BYU have the concern of distributing images to the public and in-turn persons from the public fraudulently change the images and […]
Frequency Response of Skin Vibration on the Head and Neck during Speech
Ben Pence and Dr. Scott Thomson, Mechanical Engineering During speech, the vocal folds vibrate resulting in audible sounds. In addition to being transmitted through the vocal tract these vibrations are also transmitted through several layers of various types of tissue throughout the head and neck, resulting in small, but measurable, skin surface vibration. Contact microphones […]
A Self-Powered Wireless Microphone
Joel Neff and Dr. Brian D. Jensen, Mechanical Engineering The idea for our project was to use vibrations from the human vocal folds to harvest energy during speech. This energy would then be used to power a wireless throat microphone, which would acquire a speech signal and then transmit it to a fixed receiver for […]
Microfabrication of Electron Sources
Jeffrey Maas and Dr. Aaron Hawkins, Electrical Engineering Microfabrication of Electron Sources as it applies to Chemical Sensors has been a useful project. With the decreasing dimensions of the handheld mass spectrometer it is becoming increasingly more important to develop an on board electron source for localized source emission. This project has been undertaken as […]
