Probabilistic Cable Aging Diagnosis And Prognosis With Reflectometry And Capacitance Methods, Xuan Wang
Probabilistic Cable Aging Diagnosis And Prognosis With Reflectometry And Capacitance Methods, Xuan Wang
Theses and Dissertations
Safe and reliable operation of power plants and power transmission are critical to economy and society. Cables in power generation and transmission are subject to various thermal, chemical, and mechanical stresses, which generally lead to aging and degradation of cable insulation. It is reported that some cables with a projected lifetime of 40 years need to be replaced in 10-15 years. Poorly maintained aged cables can adversely affect power delivery and lead to catastrophic events, such as blackout, fires, and loss of lives. The current research on cable is mainly focused on the detection and localization of hard faults, which …
Achieving Sustainability In Urban Transit And High-Occupancy Vehicle Systems Through Emerging Technologies And Operations, Ruixiao Sun
Theses and Dissertations
It is critical to reduce road transportation emissions, as it is the major source contributing to greenhouse gas emissions (GHGs) and air pollution. However, the increasing travel demand due to the rise of population and economy makes the task challenging. Mathematically, road transportation emissions can be minimized in the manner of reducing total vehicle miles traveled (VMT) and lowering vehicle emission rate. Many strategies have been proven viable for achieving transportation sustainability. For example, the total VMT can be reduced by switching low-occupancy transportation modes (i.e., driving alone) to high-occupancy transportation modes (i.e., public transit, ridesharing). The development of alternative-fuel …
Improving Ideation Of User Actions Using A Novel Ideation Method, Thomas L. Ashworth
Improving Ideation Of User Actions Using A Novel Ideation Method, Thomas L. Ashworth
Theses and Dissertations
During early stages of the design process, ideation methods are used to generate a set of potential solutions based on a particular need. Solutions to design problems generally require both technology and user actions (or tactics) of some sort, although solution ideas may omit explicit mention of either technology or tactics. Previous research suggests that an explicit consideration of tactics in early-stage ideation enables design teams to improve the quantity, quality, variety, and novelty of their idea sets. In this paper, a novel ideation method known as the Random Prompts method is presented, and its performance is evaluated against a …

An Investigation Of The Impact Gender-Specific Course Grouping Has On Female Middle-School Students' Concept Of And Interests Toward Technology And Engineering, Thomas Broderick Walsh
Theses and Dissertations
Attempts to improve retention, interest, and enrollment of females in Technology & Engineering Education courses have included a variety of approaches including female-only classes. However, the implications of such courses have not been thoroughly investigated. Therefore, an investigation of female-only classes was undertaken; the findings revealed that the overall enrollment of females went up in the course and in subsequent classes, these students maintained their interests and attitudes towards Technology and Engineering, their perceptions of an engineer's gender changed from that of mostly male to mostly female, and their concepts of what an engineer does changed from mostly building or …
Technology And Tactics As Dimensions Of Design: Explicit Representation Of User Actions In The Product Design Space, Tyler Stapleton
Technology And Tactics As Dimensions Of Design: Explicit Representation Of User Actions In The Product Design Space, Tyler Stapleton
Theses and Dissertations
The initial phases of the design process -- including interactions with stakeholders, ideation of concept candidates, and the selection of the best candidates --- have a large impact on the success of a project as a whole. Much of the value generated during these phases comes from the designers' exploration of the design space as they create concepts for the final solution. Unfortunately, an entire dimension of the design space is often ignored during the initial phases of the design process -- the tactics dimension. Engineers tend to emphasize the design of technology in their work, while paying less attention …
Enhancements In Alginate Microencapsulation Technology & Impacts On Cell Therapy Development, Marwa Belhaj
Enhancements In Alginate Microencapsulation Technology & Impacts On Cell Therapy Development, Marwa Belhaj
Theses and Dissertations
Biodegradable alginate microcapsules (MC) are recently becoming widely used in the biomedical field, and have shown effectiveness as a drug delivery system. Alginate has been used in microencapsulation due to its simple gelling process, biodegradability, excellent biocompatibility, and its stability under in-vivo conditions. Alginate polymer is a natural polysaccharide derived from brown seaweed and has the ability to polymerize rapidly in the presence of cations to form a porous matrix. In order to advance the previous system for efficient protein and peptide delivery, we further lyophilized the peptide-filled microcapsules and we were able to rehydrate, and test them for sustained …
An Investigation Of The Impact A Rov Competition Curriculum Has On Student Interest In Stem, Specifically Technology And Engineering, Daniel Gordon Bates
An Investigation Of The Impact A Rov Competition Curriculum Has On Student Interest In Stem, Specifically Technology And Engineering, Daniel Gordon Bates
Theses and Dissertations
This research investigates the impact a Remotely Operated Vehicle (ROV) program has on student interest in, and perception of, technology and engineering (sTEm). ROV programs embed areas of science, technology, engineering and math (STEM) into their curriculum; however, emphasis for this study is placed on interest and perception of the "T" and "E" of STEM. Although there are many articles detailing the benefits of ROV programs, there is little empirical data documenting the impact on student interest and perception of sTEm. This study outlines the background of a few major ROV programs in the U.S.; specifically Utah Underwater Robotics (UUR), …
