Comparison of the Accuracy and Applicability of Forebody Wake Effect Models for Parachute System Design

Creator:: Kemling, Gabriel H. and Blunck, David L.
Abstract:: The forebody wake effect (FWE) is important to consider when designing parachute systems because it can affect parachute performance. Parachutes work by altering the aerodynamic properties of an attached forebody to control a descent. The FWE can reduce parachute drag, causing the system to descend faster than desired. This drag...

Multi-Scale Study of Ember Production and Transport under Multiple Environmental and Fuel Conditions

Creator:: Hudson, Tyler R.
Abstract:: Spot fires caused by lofted embers (i.e., firebrands) can be a significant factor in the spread of wildland fires. Embers can be especially dangerous near the wildland-urban interface (WUI) because of the potential for the fire to be spread near or on structures. Many studies have investigated the transport of...

Temperature Evolution of Nonreacting Spark Kernels at Sub-Atmospheric Pressures

Creator:: Caplan, Daniel L.
Abstract:: In the event of a mid-flight flameout of a gas turbine engine, reignition is paramount to occupant safety. Ignition at high altitude can be challenging, due in part to the potentially lower ambient pressures. An understanding of the effects of sub-atmospheric pressures on the temperature evolution of spark kernels is...

Acceleration of Long-Range Ordering in NiCrFe Alloys Via Proton Irradiation

Creator:: Evered, Cole E.
Abstract:: This work explores the hypothesis that proton irradiation is a feasible alternative to simulate accelerated thermal aging for Ni2Cr long-range ordered phase formation within NiCr and NiCrFe alloys. In this study, various model alloys and commercial alloys 690 and 690+P (0.01 wt.% P) were subject to 2 MeV proton irradiation...

Chemical Solution Deposition and in-situ Structural Characterization of Pb-free, Bi-based, Piezoelectric Thin Films

Creator:: Fox, Austin J.
Abstract:: This work explores the electric field induced strain mechanisms in environmentally benign Bi0.5Na0.5TiO3 (BNT) based piezoelectric thin films. Although BNT-based materials show promise as replacements for toxic Pb-based piezoelectrics, the displacement mechanisms are not consistent between thin films and bulk materials, and the differences have yet to be well understood....

Computational Modeling of Smoldering Combustion in Wildland Fuels

Creator:: Jayasuriya, Waduge Jayani A.
Abstract:: Smoldering combustion in wildland fires is a critical phenomenon that needs in-depth study because it can initiate with weaker ignition sources, can persist for long periods, is difficult to suppress, and can transit to flaming combustion. Cellulose, hemicellulose, and lignin are the major organic constituents within biomass, in varying proportions...

Adaptive Learning Module for Introduction to Materials Science

Creator:: Nigon, Nutnicha
Abstract:: There is a growing need for individualized instructional designs in 4-year institutions due to: 1) growing undergraduate enrollment trends across the U.S., 2) broader diversity in students backgrounds, and 3) the growing prevalence of asynchronous remote learning. With the growth in computer technology in education, tools such as adaptive intelligent...

Designing and Evaluating a User Interface for Multi-Robot Furniture

Creator:: Stoddard, Brett
Abstract:: A chair, once placed, will stay put until moved. Or will it? With the rise of technology being embeddable into everyday objects, what if that chair could move itself? Such robotic furniture has been featured in advertisements, art, and Human-Robot Interaction (HRI) research. Existing methods for operating robotic furniture have...

Initial Designs for Improving Conversations for People Using Speech Synthesizers

Creator:: Nguyen, Duy M.
Abstract:: This thesis aims to determine the impact that Augmentative and Alternative Communication (AAC) devices have on social interactions, and then improves the AAC user experience through a user focus design process. AAC devices enable people who cannot speak to communicate with others. Unfortunately, they are tedious to use and make...

Evaluating the Effect of Emotions on Student Learning using Prescriptive and Open-ended Lab Activities for a Lean Manufacturing Engineering Course

Creator:: Perez, Maritza
Abstract:: Research has shown that emotional connections during lab activities increase learning in chemistry and physics courses. However, little research has examined the effects of emotion in engineering courses, and these studies have recognized a dearth of research examining the ability of students to apply engineering concepts in real-world applications based...
