Study Of Si-Gan Photoconductive Switches Operating Modes Using Near-Ir Radiation, Nicolas Eduardo Gonzalez Padilla

Electrical and Computer Engineering ETDs

One of the most promising solid-state devices for fast switching and radio frequency generation applications is the photoconductive switch (PCSS). These devices have been thoroughly explored since the late 1980s and exhibit remarkable switching properties in gallium arsenide (GaAs). With recent advances in wide bandgap (WBG) semiconductor manufacturing processes, there has been an increasing interest in using WBG semiconductors to implement PCSS. WBG semiconductors could exhibit the same switching characteristics as GaAs while overcoming their poor power management and short lifetime under pulsed power conditions, making PCSS a reliable option in high-power applications. Gallium Nitride (GaN) has emerged as one …

Oxygenic photosynthesis supports the majority of life on Earth through the capture of energy from sunlight and the assimilation of CO2 into basic building blocks of cells. Microalgae are fast growing and account for about half of global photosynthesis. In addition, they can be cultivated and their metabolism can be redirected to generate additional useful products ranging from biofuels to pharmaceuticals. However, the efficiency of metabolite production is severely impacted by the slow diffusion of CO2 through water and the high energetic costs of harvesting microalgae from liquid cultures. Microalgae grow in open water, but they also form …

Reference Governor For Air-Conditioner, Ganiyu E. Azeez Nov 2023

Reference Governor For Air-Conditioner, Ganiyu E. Azeez

Mechanical Engineering ETDs

Advanced control for heating ventilation and air-conditioning (HVAC) systems has primarily focused on optimizing energy efficiency. However, ensuring the safe and reliable operation of HVAC equipment is another crucial control objective. This Thesis presents a reference governor (RG) that can augment existing energy-optimized controllers with the capability to enforce constraints to ensure safe and reliable operation. The RG makes minimal adjustments to the reference room temperature setpoint to ensure that the refrigerant entering the compressor is super-heated, thereby preventing potential damage. Designing the RG requires synthesizing a constraint admissible positive invariant (CAPI) set which characterizes the subset of states for …

A high-fidelity computational solver was developed with direct numerical simulation (DNS), large eddy simulation (LES), and Concurrent Precursor Method (CPM) capabilities. Extensive validation ensured the solver's accuracy in modeling fluid dynamics, including the wake characteristics of both utility and miniature-scale wind turbines. Key performance statistics (e.g., velocity and turbulence intensity profiles) were compared against established theoretical, computational, and experimental results. The study examined the influence of ground clearance on turbine performance, comparing two scenarios with different hub heights. Results showed that larger ground clearance facilitates quicker wake recovery. Finally, the study uses a nine-turbine array model to explore wind farm …


A Phenomenological Study Of Successful Superintendent Retention In A North-Central New Mexico School District, Adán G. Delgado Nov 2023

A Phenomenological Study Of Successful Superintendent Retention In A North-Central New Mexico School District, Adán G. Delgado

Teacher Education, Educational Leadership & Policy ETDs

Superintendent of Schools is uniquely critical in a school district due to its tremendous effect on the operational and cultural bearing of the organization (Myers, 2011). Superintendent turnover can hinder district reform and improvement (Grissom & Andersen, 2012; Marzano, 2006). The United States and New Mexico struggle with superintendent retention and northern New Mexico is especially plagued with short superintendent tenure (Grissom & Andersen, 2012; NMPED Stat Books, 2021; Sawchuck, 2022). In this study, I investigated the initial selection and subsequent interactions and relationships between school board members and superintendents. Using a phenomenological approach, I interviewed two superintendents and four …

Improving Human-Automation Collaboration In Motion Planning, Torin J. Adamson Oct 2023

Improving Human-Automation Collaboration In Motion Planning, Torin J. Adamson

Computer Science ETDs

Human-automation collaboration is becoming a part of everyday life as AI helps us drive, make decisions, and solve a variety of other tasks. However, safe and effective collaboration systems depend on factors in trust, communication, and more. Existing studies to explore these are typically carried out in laboratory settings, providing robust data under tight environmental control. However, human behavior evolves over time, driven by external factors that cannot be fully captured in single participation sessions. These factors form the "human context", contextualizing the behavioral data for a more complete understanding. In this thesis, video game adaptations upon conventional subject studies …
