Michael Farnsworth and Faculty Mentor: Brian Iverson, Mechanical Engineering Introduction There are three major types of heat transfer: conduction, convection, and radiation. In many cases, radiation is ignored due to the fact that the amount of heat transferred by this method tend to be small compared to conduction and convection. However, in space and in […]
Design and Comparison of Variable-Stiffness Compliant Joints for Haptic Devices
David Usevitch and Faculty Mentor: Mark Colton, Mechanical Engineering Introduction Haptic interfaces or devices are computercontrolled robotic systems that seek to replicate the touch experience of a human user1. The purpose of this research is to develop a viable variable-stiffness compliant joint for haptic interfaces that eliminate rotation joints or screw mechanisms that induce friction, […]
Safety Analysis of a Flashing Drum Steam Generation System
Jacob Ladd with Cade Memmott, Chemical Engineering Introduction The goal of the Integral, Inherently Safe Light Water Reactor (I2S-LWR) Research Project is to design a more inherently safe reactor. This reactor is capable of cooling the core with no external power and no operator action.[1] In the I2S-LWR design, micro-channel heat exchangers (MCHX) facilitate heat […]
Safety of Tubular Nylon Webbing: The Effect of Wet and Cold Environments
Caleb Duncan and Landon Wright with John Salmon, Mechanical Engineering Tubular nylon webbing is an effective and relatively inexpensive anchoring solution for search and rescue groups, fire departments, canyoners, and rock climbers. As an anchoring solution nylon webbing is vital to the safety of anyone who uses it. Serious injury or death will often occur […]
Effect of Thickness on Fatigue Life on Creased Thin PLA
Peter Schleede with Larry Howell, Mechanical Engineering Introduction Origami-based engineering creates products that solve problems inherent in other designs. For example, they can compress into smaller volumes, achieve new and unique motions, and lessen or mitigate numbers of welds, fasteners, or other joining methods. However, a weakness of these designs is the necessity of folding […]
Development of a Flow Duration Curve to Determine Hydropower Feasibility
Susan Estep with Elise Estep and Dr. Jim Nelson, Civil and Environmental Engineering The purpose of this project was to derive Flow Duration Curves (FDCs) by three separate methods in order to compare the accuracy of these methods. The FDCs would be used to estimate the amount of water that would be consistently available for […]
Droplets Rolling on Superhydrophobic Inclines Simulating Real World Application Environments
Braquel Burnett and Faculty Mentor: Julie Crockett, Mechanical Engineering Superhydrophobic surfaces offer unique characteristics such as extreme water repellency, drag reduction and enhanced condensation rates. These effects are possible due to a combination of micro/nano-texturing and a hydrophobic chemical coating. With the advent of micro/nano-fabrication, research and development on superhydrophobic surfaces has sky-rocketed due to […]
The Influence of Crystallographic Constraints on Percolation
Jarrod Lund and Faculty Mentor: Oliver Johnson, Mechanical Engineering Introduction Within polycrystalline materials (e.g. metals and ceramics), grain boundary networks (GBN) influence the effective properties such as diffusion, conductivity, and crack and creep propagation1. In precision applications such as jet engine turbine blades and solid oxide fuel cells, understanding and characterizing GBN are essential for […]
Let’s Find Out! Motivating Motivational Interview Evidence-based Practice in TR
Lora Hughes and Neil Lundberg, Recreation Management Introduction Diseases related to aging, developmental disorders, mental illnesses, acquired physical disabilities, and traumatic events cause untold human suffering each year. Many professionals seek to alleviate such suffering, including the discipline of therapeutic recreation (TR), which uses a holistic process of targeted interventions, leisure education, recreation participation, and […]
The Impact of Government Loan Expansion on Post-Graduation Outcomes: A Longitudinal Study
Mark Johnson and Taylor Nadauld, Department of Finance Introduction The availability of higher education is linked to more affluent and prosperous societies. In the United States, policy makers have attempted to make post-secondary education readily available through grants and loans. In the past two decades student loans have exploded to become the second largest segment […]
