Adaptive Protection Scheme For A Real-World Microgrid With 100% Inverter-Based Resources, Trupal Patel

All Theses

The integration of renewable and distributed energy resources to the electric power system is expected to increase, especially at the distribution level. As more renewable generation connects to distribution systems, it is imminent that existing distribution feeders will be converted to microgrids. Microgrids are systems, typically at distribution voltage level, sustained by distributed and often renewable sources, that can operate in grid-connected and islanded modes. Microgrids offer resilience by providing the flexibility of supporting the grid in normal operation and operating as self-sustained islands when the grid is disconnected.

As the grid transforms to a modular system consisting of many …

Fruit Bagging: A Small-Grower And Consumer Horticultural Practice Across The Southeastern United States, Ann Katherine Kule

A New Family Of Fault Tolerant Quantum Reed-Muller Codes, Harrison Beam Eggers

All Theses

Fault tolerant quantum computation is a critical step in the development of practical quantum computers. Unfortunately, not every quantum error correcting code can be used for fault tolerant computation. Rengaswamy et. al. define CSS-T codes, which are CSS codes that admit the transversal application of the T gate, which is a key step in achieving fault tolerant computation. They then present a family of quantum Reed-Muller fault tolerant codes. Their family of codes admits a transversal T gate, but the asymptotic rate of the family is zero. We build on their work by reframing their CSS-T conditions using the concept …

Stock Plant Management Techniques Affect Postharvest Flower Development Of Impatiens ×Hybrida, Mary Anna Vargo

All Theses

Stock plants provide a supply of unrooted cuttings for the asexual propagation of selected ornamentals. The primary goals of stock plant management are to maintain completely vegetative plants and to maximize shoot production. However, the result of producing vegetative cuttings can be slow production time, i.e., long production schedules for the greenhouse business that propagates and flowers the plants. Therefore, the first objective was to examine alternate methods of stock plant management in order to produce cuttings that flower in a shorter time period, e.g., 5-6 weeks from the start of propagation (“sticking”). Hybrid impatiens (Impatiens ×Hybrida) …

Cost-Benefit Analysis Of Constructing And Operating A Streetcar System In Buffalo, Ny, Daniel Kevin Zielinski

Applied Economics Theses

In about 30 of the largest 300 US metro areas, fixed-rail electric streetcars have been reintroduced or refurbished after 75 years of policy favoring petroleum-powered buses. Unlike buses, new streetcar systems are designed to enhance or regenerate economic activity along their routes in urban centers that lack the population density to support subway systems. This paper assesses the criteria utilized by the US Department of Transportation in its decision-making process for supporting streetcar projects. Using multi-factor cost-benefit analysis, a model of a potential streetcar reintroduction for Buffalo, New York is presented.

Improving Emergency Airway Care At A Critical Access Hospital, Kelly Mitchell

Student Projects for Graduate Degrees

Emergency airway care is of the highest priority in caring for patients arriving at the emergency department with critical injuries and conditions. Intubation via laryngoscopy is the gold standard for placing an endotracheal tube to manage ventilation. In rural areas, emergency airway care is often the responsibility of non-expert providers who rarely have the opportunity to perform this life-saving procedure. These less experienced providers often take a longer time and make more attempts at endotracheal intubation. Multiple attempts and increased time taken to secure an airway are associated with higher morbidity and mortality. A critical review of the literature supports …
