Cameron Bell and Dr. Matthew Jones, Mechanical Engineering The development of a light woodstove that is able to be conveniently packed is of great importance for anyone in an emergency situation. The ability to purify water by boiling it, cook food, and reduce food weight by bringing dry ingredients could dramatically increase the chances of […]
CNT Adhesion
Devan Anderson and Professor Brian Jensen, Mechanical Engineering Introduction Carbon Nanotubes (CNTs) are grown on a silicon wafer that usually has had various metals deposited onto the surface. For many applications of CNTs it is desirable that the CNT arrays remain attached to the silicon wafer, however, thus far the CNT community has been unsuccessful […]
An Investigation of Methods for Actuating Robot Arms: Direct vs. Pulley vs. Bowden Cable Actuation Methods
Dallin Swiss and Dr. Mark Colton, Mechanical Engineering Introduction A group of BYU researchers and therapists designed a robot named “Troy” for use in studies to investigate robot-assisted therapy for children with autism [1]. Troy was considered effective and successful but studies suggest that developing a new robot with greater realism and additional capabilities may […]
Measuring Combustion Efficiency of Improved Cookstoves and Associated Air Quality
Whitney Steed, Erin Hamson, and Jeff Lord with Dr. Matt Jones, Mechanical Engineering Introduction Statistics report that approximately three billion people in the world prepare their meals using solid fuels1. The incomplete combustion that comes from burning these solid fuels creates harmful fumes and particulate matter that damage human health. Our goal was to create […]
An Analytical Model for Heat Transfer through a Thermoelectric Device Used in Waste Heat Recovery
Zachary Smith and Dr. Matthew Jones, Mechanical Engineering Introduction A considerable amount of energy that is produced in a typical power generation process is rejected to the environment as low-grade waste heat. This heat is rejected at a temperature that is difficult to efficiently convert into electricity. One promising method of recovering this waste heat […]
Stability of n=6 Normal and Right-Angled Kaleidocycles Under the Influence of Energy Elements
Brett Rowberry and Dr. Larry Howell, Mechanical Engineering Normal and right-angled n=6 kaleidocycles are structures composed of six tetrahedra. They are capable of continuous rotation while only requiring 240° of rotation on each joint between adjacent tetrahedra. Because of this fact, kaleidocycles may be made fully compliant with no moving parts. Having continuous rotation in […]
Design of a Robot Head for an Assistive Robot used in the Clinical Treatment of Children with Autism
Jacob Robinson and Dr. Mark Colton, BYU Mechanical Engineering Introduction Autism is a spectrum disorder that is characterized by an impairment of the child’s social relationships, communication skills, and imaginative thought, resulting in a decreased quality of life for the child and his or her family, as well as significant economic costs to society. Although […]
Influence of Intermediate Lamina Propria Composition on Synthetic Vocal Fold Vibration: A Comparison of the EPI and Stiff Ligament Models
Ryan Jenkins and Dr. Scott Thomson, Mechanical Engineering Introduction: The vocal folds are two multi-layered regions of tissue located in the larynx that vibrate as air flows past from the lungs. This vibration is the basis of voiced speech, one of mankind’s primary means of expression. Due to a complex fluid-structure-acoustic interaction and the inaccessibility […]
Direct Generation of Smart Pareto Sets in Multiobjective Optimization
Braden Hancock and Dr. Christopher A. Mattson, Mechanical Engineering Department Introduction In October 2013, we proposed the development of a method to directly generate smart Pareto sets of solutions in multiobjective optimization problems. Thanks to the opportunity that we received to pursue this research through an ORCA grant, we were able to develop that technology […]
Development of a One-piece, Aramid-polyurethane Bumper System For Automobiles
Brent Zollinger and Dr. Christopher Rotz, Mechanical Engineering The automobile bumper system—consisting primarily of a decorative fascia, structural cross-beam, and energy absorber—is an ideal candidate for redesign using advanced technology. This report examines a concept that integrates the three main components of the bumper system into one by using high-performance materials. A one-piece, aramid-polyurethane composite […]
