Laura L. Huntzinger and Dr. Harold L. Miller, Psychology Self-control has been defined by researchers as choosing larger, more delayed reinforcers over smaller, less delayed reinforcers (1). The term impulsiveness is used to describe the opposite of self-control, that is, choosing smaller, less delayed rewards rather than larger but more delayed rewards. Research involving adult […]

Statistical Process Control Methods for Multiple Stream Processes: A Comparative Study
Jared Caleb Christensen and Dr. Scott D. Grimshaw, Statistics The Shewhart control chart is the most common statistical process control (SPC) tool used to determine stability. One fundamental assumption of the Shewhart chart is that the output comes from a single, continuous stream. This implies the monitoring of a single source of variation. Filling machines […]
Synchronous Data Link Control Communication Chip
C. Alva Barney and Dr. Doran K. Wilde, Electrical and Computer Engineering In conjunction with the ORCA research grant I was able to design, layout and simulate an integrated Synchronous Data Link Control (SDLC) communication chip. SDLC communication chips are commonly used to transfer data between computers in serial bit-wise transmission. Extensions of the SDLC […]
Control Chart Development for the Coefficient of Variation
Geraldine Madariaga and Dr. C. Shane Reese, Statistics Introduction Industries use control charts to evaluate whether or not a process is “in control” or producing parts that meet the standards of quality. Control charts are based on the principle that variation between samples can be predicted based on sampling distributions. Parts are measured and the […]
Broadband Active Noise Control for Small Axial Fans
Scott Jensen and Dr. Scott Sommerfeldt, Physics and Astronomy The problem of actively reducing noise from a small axial fan, a.k.a. a computer fan, is a complicated and difficult problem. A team of several BYU students have been working on the problem for about four years now. About a year ago, we started to solve […]
An Ultra-Stable Laser Current Controller
Marshall van Zijll and Dr. Dallin Durfee, Physics Our research group has spent lots of effort and time building an ultra-stable laser current controller. This stability is essential for our application of atom interferometry so that our measurements could be very precise. The overall development of our controller has taken almost a year longer than […]
MULTIDRUG-RESISTANT TUBERCULOSIS: STRATEGIES FOR IDENTIFICATION AND CONTROL
Wendy Chao and Dr. Richard Robison, Microbiology After over a century of decline, tuberculosis (TB) has re-emerged as the leading killer among infectious diseases. In addition, Mycobacterium tuberculosis, the causative agent of TB, has developed strains resistant to multiple antibiotics, making the disease increasingly difficult to treat. Rapid diagnosis is critical in treating multidrug-resistant TB […]
PRESSURIZED, CONTROLLED ATMOSPHERES AS A METHOD OF LONGTERM PRESERVATION OF FRUIT
Stuart C. Wooley and Dr. Darrell J. Weber, Botany and Range Science The bane of all fruit growers and sellers is that fruit rots either before and during transport or on the store shelf. This creates income loss for the grower and grocer and reduces quality of produce. For example, some fruits like strawberries have […]
TRANSLATIONAL CONTROL OF POLY(A)-BINDING PROTEIN EXPRESSION
Eliott Spencer and Dr. Roger Kaspar, Chemistry Poly(A)-binding protein or PABP is found in high concentrations in all eukaryotic cells. Cell biologists have speculated for a long time that PABP plays an important role in stabilizing the fragile MRNA molecule so that it can be more effectively translated into its final gene product. PABP does […]
Body Weight and Self-control in Pigeons
Daniel Watkins and Dr. Harold Miller, Psychology Recent approaches have interpreted self-control in terms of temporal factors. Most recent models posit that self-control amounts to a choice between a smaller reward that is available sooner and a larger reward that is available later. The model is applicable to both humans and nonhumans. Additionally, the model […]
