The Effects of a User Interface on Productivity The Whiteboard LMS

by

Jeremiah Jackson and Dr. Barry Mark Lunt, Information Technology Common among modern universities, BYU included, is usage of Learning Management Systems, commonly known as LMS. LMS are electronic classrooms, often online, that allow for the learning process to continue outside of the traditional classroom setting. For several years, BYU has strived to use the Blackboard […]

Zero Power Shock Sensors Using Bistable Compliant Mechanisms

by

Brett Hansen and Dr. Stephen Schultz, Electrical and Computer Engineering There are various applications for shock sensors, ranging from cell phones, to postal packaging, to automobile safety designs. These devices are designed to indicate when a predetermined threshold of impact force has been experienced. The designs of these sensors are varied. Some employ electrical stimuli […]

Development of Models of Laryngeal Cartilage Using MRI Images

by

Brianne Hamilton and Dr. Scott L. Thomson, Mechanical Engineering The study of vocal fold vibration allows for greater understanding of how speech production occurs and of the prevention, diagnosis, and treatment of associated physiological disorders. Until now an environment to test vocal fold models which are anatomically similar in both form and function has not […]

Fiber-Optic Chemical Sensor

by

John D. Gordon and Dr. Stephen Schultz, Electrical and Computer Engineering Volatile organic compounds (VOC’s) are valuable throughout many industrial and academic settings. These chemicals, however, often raise environmental and health related concerns. For example, chlorinated hydrocarbons (CHC’s) are often used as cleaning solvents but have significant ozone depleting potential. In addition, many CHC’s are […]

Impedance Detection of Biological Molecules in Microfluidic Channels

by

Daniel Evans and Dr. Aaron Hawkins, Electrical and Computer Engineering At the current time, the most sensitive detection methods for biological molecules are based on fluorescent tags. This requires the use of optical sources and detectors as well as the introduction of a fluorophore that can be attached to a molecule of interest. In light […]

The Mechanism of Gravity Induced, Counter-current Flow of Oil and Water in Porous Beds

by

Kari Cook and Dr. Hugh Hales, Chemical Engineering Purpose Computerized simulation of the flow in underground petroleum reservoirs is widely used by oil companies to optimize the production of oil and gas. Such simulations are known in the Industry as “reservoir simulation”. They are based on Darcy’s Law, smoothly varying flow potentials, and the assumption […]

Polyurethane (PU) Foam Synthesis and Lean Manufacturing An Effective Business Suitable in Developing Countries

by

Sebastian Acosta, Danny Parades, and Dr. Robert Todd. Department of Mechanical Engineering Our ORCA project was motivated by the realization that many South American countries have not taken full advantage of the polyurethane industry. The manufacturing of PU and its applications may contribute to the economic and social growth in less-developed nations. This may be […]

Twelve-month-olds’ Discrimination of Monkey Faces: Evidence for Perceptual Narrowing?

by

Ross Magnum and Dr. Ross Flom, Department of Psychology Experience plays a critical role in the development of infants’ perceptual abilities. Studies have shown that during the early stages of development, about six months of age, infants are capable of discriminating between a large number of faces, including faces from different species or races (Pascalis, […]
