Patrick J. Sedivy and Dr. Fernando S. Fonseca, Civil and Environmental Engineering The Problem Pultruded Fiber-Reinforced Polymer (FRP) structures are an attractive alternative to steel which is corrosive and heavy. However, FRP beams and columns cannot be connected using conventional methods such as bolting or welding. Anthony G. Cockbain demonstrated the potential of a monolithic […]

Torsion Testing Of The Isotruss
Jeff Brimhall and Dr. David W. Jensen, Civil And Environmental Engineering BACKGROUND The IsoTruss is an innovative structural member made up of a unique geometric configuration and composite material that has tremendous potential for use in civil infrastructure, aerospace and other applications. This unique geometric configuration, which uses minimal material, yet maintains a very high […]
Outcome Testing and the Role of Bilingual Fluency in a Southeast Asian Population
Shelby L. Ferrin and Dr. Michael J. Lambert, Psychology Psychological outcome measures are designed to measure levels of psychological functioning. Scores on such measures may be compared across time to calculate a psychotherapy client’s progress, recovery, or deterioration. Additionally, scores from large populations may be normalized to indicate what therapists designate as levels of clinical […]
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 […]
Destructive Testing Versus Nondestructive Evaluation: A Statistical Comparison
Geraldine Hansen and Dr. C. Shane Reese, Statistics Researchers and developers in manufacturing and industry are often confronted with the problem of testing component functionality. Two important testing methods used on equipment are destructive testing (DT) or nondestructive evaluation (NDE). DT implies that the part is destroyed by disassembly, or it is destroyed by utilizing […]
Static Strength and Durability Testing of Biomass Fly Ash in Concrete
John Hema and Dr. Fernando Fonseca, Civl and Environmental Engineering Fossil fuels are used in modern power plants throughout the world to produce electrical energy. This process increases air pollution and generates millions of tons of a by-product known as fly ash. Fly ash is the inorganic residue that remains after pulverized coal is burned. […]
Fatigue Testing a Laminated Compliant Clutch
Daniel Brown and Dr. Robert H. Todd, Mechanical Engineering Compliant mechanisms derive motion from flexible segments, rather than from joints. A BYU student, Nathan Crane, used compliant design concepts to develop a prototype centrifugal clutch.1 Manufacturing considerations led to a design incorporating many layers rather than a single solid piece.2 Further testing verified the engagement […]
Testing Cognition in Amazona spp
Heidi Francis and Dr. Steven L. Peck, Integrative Biology Animal intelligence has been studied for years, yet very few people are aware that parrots are ranked near the top with regards to cognition. For almost 20 years Dr. Irene Pepperberg has been teaching African Grey parrots to communicate using language, these birds then use English […]
Defining Species Concepts: Testing Species Boundaries of Sceloporus Grammicus
Daniel H. Chappell and Dr. Jack W. Sites, Jr. Integrative Biology Species concepts are the methods biologists use to name and describe species. There are many important reasons for having an empirically based species concept. Species definitions are important to the fields of population biology and phylogenetics. Species are the fundamental unit of evolution. Operationally […]
Testing the Fisher effect under fractional integration
Mark J Jensen and Scott G. Murdock, Economics Abstract. In this paper we model inflation and the nominal interest rate as a fractionally integrated, autoregressive, moving average (ARFIMA) process in order to test the theoretical proposition that nominal interest rates move one for one with inflation, thus, leaving the real interest rates unchanged; i.e. the […]
