Mitigating Diminishing Manufacturing Sources/Material Shortages (Dms/Ms) And Obsolescence For The T-6 Canopy Fracturing Initiation System (Cfis), Richard P. Carrano

Theses and Dissertations

The Joint Primary Aircraft Training System (JPATS) lost the supplier for its canopy fracturing initiation system (CFIS) with no prospect for a replacement. This forced a complete CFIS redesign to supply both an active production line and sustain fielded aircraft. Compounding the problem, the existing CFIS became obsolete, which forced an interim design to be produced until a final long term solution was fielded. This thesis developed a method to optimize the redesign by determining the lowest cost path for both fielding the interim design and phasing in the final retrofit. Using the Excel Solver® modeling program, an optimal rate …

Simplified Daylight Spectrum Approximation By Blending Two Light Emitting Diode Sources, Jacob M. Gilman

Theses and Dissertations

Energy-conscious facility designs strive to include natural daylight in workspaces. To improve the efficiency of illumination, significant efforts are underway to adopt more efficient light emitting diode (LED) lamps and to effectively integrate daylight with active dimming of electric lighting. However, the correlated color temperature (CCT) and spectral content of daylight varies throughout the day while existing electric light sources produce light with a fixed CCT, resulting in mixed-illumination environments. The color rendering requirements for a lamp that permits the selection of color temperature across a significant portion of the daylight locus is explored. The analysis indicates that it is …

Ql+ Body Temperature Regulating Vest, Melissa Goss, Brittnee Cubero, Dillon Lynch, Greg Olsen, Julian Jazayeri

Biomedical Engineering

The purpose of this project is to design a thermal vest to be worn by individuals with spinal injuries to help regulate their core body temperature. Individuals with spinal injuries have impaired thermoregulation abilities which increase their susceptibility to succumbing to either heat stroke or hypothermia. This project focused on preventing heat stroke by inducing a cooling mechanism. To provide this cooling mechanism, a thermoelectric cooler was used to chill water in a reservoir. This water is then pumped through tubing sewn into the vest. The chilled water will absorb heat from the human body and return to the reservoir. …

Engineering Leadership, Mike Murphy, Eugene Coyle

Books/Book chapters

By 1921 the American sociologist Thorstein Veblen in his book The Engi-neers and the Price System argued for a technocracy in which the welfare of humanity would be entrusted to the control of the engineers because they alone were competent to understand the complexities of the industrial system and processes and thereby optimize and maximize its output. This chapter sets out to explore the extent to which Veblen’s technocratic leadership thesis has come to pass. We first review the role of the engineer in society and in the context of Europe, the US and China, and examine the influence of …

Fall Risk Assessments Based On Postural And Dynamic Stability Using Inertial Measurement Unit, Jian Liu, Xiaoyue Zhang, Thurmon E. Lockhart

Computer Sciences and Electrical Engineering Faculty Research

Objectives: Slip and fall accidents in the workplace are one of the top causes of work related fatalities and injuries. Previous studies have indicated that fall risk was related to postural and dynamic stability. However, the usage of this theoretical relationship was limited by laboratory based measuring instruments. The current study proposed a new method for stability assessment by use of inertial measurement units (IMUs).

Methods: Accelerations at different body parts were recorded by the IMUs. Postural and local dynamic stability was assessed from these measures and compared with that computed from the traditional method. Results: The results demonstrated: 1) …

Hispanic Maternal And Children's Perceptions Of Neighborhood Safety Related To Walking And Cycling, Norma Olvera, Dennis W. Smith, Chanam Lee, Jian Liu, Jay Lee, Stephanie Kellam, Jun-Hyun Kim

Computer Sciences and Electrical Engineering Faculty Research

This study examined neighborhood safety as perceived by children (mean age=10 years) and their mothers, and its association with children's physical activity. For all eight safety items examined, children perceived their environment as less dangerous than mothers (p<0.05). None of the multiple regression models predicting children's physical activity by safety perceptions were significant (p>0.10). The maternal perception model explained the highest percentage of variance (R²=0.26), compared to the children's perception model (R²=0.22). Findings suggest that future studies should explore relations between self-reported and objectively measured safety barriers to Hispanic youth walking and cycling.

Design And Experimental Validation Of Continuous Dna Separation Using Itp-Based Microfluidic Device, Nora C. M. Goscinski, Mary E. Rosa, Elizabeth K. Wheeler, Maxim Shusteff

Chemistry and Biochemistry

We have demonstrated a chip-based microfluidic device suitable for rapid and high-throughput DNA separation and purification for downstream analysis.

Application Of Drum-Buffer-Rope Methodology In Scheduling Of Healthcare System, Arefeh Mohammadi, Emmanuel S. Eneyo

Durham School of Architectural Engineering and Construction: Faculty Publications

Theory of constraints (TOC) is a management philosophy that seeks to increase throughput (efficiency or performance) of the system by identifying those processes that are constraining the system bottlenecks. There have been very few profound studies of TOC in health care systems. In order to fill this gap, this study was conducted to determine how healthcare systems are utilizing components of TOC to schedule operations and what results are being obtained. This is done by using a patient flow model for a radiotherapy section of a hospital. The drum-buffer-rope (DBR) was used as the methodology for scheduling this flow. Successful …
