Three models have been created to visualize and characterize the voltage response of a standing wave accelerating cavity system. These models are generalized to fit any cavity with known values of the quality factor, coupling factor, and resonant frequency but were applied to the Arizona State Universities Compact X-ray Free Electron Laser. To model these systems efficiently, baseband I and Q measurements were used to eliminate the modeling of high frequencies. The three models discussed in this paper include a single standing wave cavity, two cavities coupled through a 3dB quadrature hybrid, and a pulse compression system. The second model on two coupled cavities will demonstrate how detuning will impact two cavities with the same RF source split through a hybrid. The pulse compression model will be used to demonstrate the impact of feeding pulse compression into a standing wave cavity. The pulse compressor will demonstrate more than a 50\% increase of the voltage inside the cavity.

The vast majority of matter found within the universe is from the dark sector composed of 75% dark energy and 20% dark matter. While the accelerated expansion rate of the universe is attributable to dark energy, dark matter is fundamentally defined as an unknown substance that interacts gravitationally with its surroundings. The research presented here investigates the methods derived from observational signatures to construct theoretical models of dark matter.

Music festivals bring large numbers of attendees together so they can enjoy themselves and listen to their favorite music. Although these festivals create a sense of community and excitement, they are some of the most unsustainable events on the globe as most festivals are powered with gas generators which spew tons of greenhouse emissions into the atmosphere. These generators can produce twice as much carbon dioxide as the power grid, and if festivals want to modernize their events to help our planet, more sustainable energy solutions are needed (Soucy, 2022). Using Tempe Beach Park as a venue for a two-day music festival, the power demands must be analyzed and then I will provide potential power solutions for this event and highlight which solutions are the best in terms of practicality, cost, and sustainability. In this report, I analyzed solar power, battery energy storage, and biodiesel, as well as other alternative solutions. I found that while solar power and battery storage are extremely expensive, they produce clean energy and do not give off any emissions. For smaller festivals, cost will be a big deciding factor in determining how to power the festival. Biodiesel serves as a cost-effective sustainable alternative that can reduce carbon emissions by up to 85%. If a festival has the budget to put in a couple hundred thousand or million dollars into the power system, they should invest that money into sustainable solutions. While biodiesel still gives off carbon emissions, it isn’t too expensive and should be used in cases where festivals are using gas generators and do not have the funds to invest in a clean power system. Festivals can decide what factors matter the most to them, and choose whether these solutions could be implemented at their festivals.

The thesis explores the avenues of machine learning principles in object detection using TensorFlow 2 Object Detection API Libraries for implementation. Integrating object detection capabilities into ESP-32 cameras can enhance functionality in the capstone dragster application and potential applications, such as autonomous robots. The research implements the TensorFlow 2 Object Detection API, a widely used framework for training and deploying object detection models. By leveraging the pre-trained models available in the API, the system can detect a wide range of objects with high accuracy and speed. Fine-tuning these models using a custom dataset allows us to enhance their performance in detecting specific objects of interest. Experiments to identify strengths and weaknesses of each model's implementation before and after training using similar images were evaluated The thesis also explores the potential limitations and challenges of deploying object detection on real-time ESP-32 cameras, such as limited computational resources, costs, and power constraints. The results obtained from the experiments demonstrate the feasibility and effectiveness of implementing object detection on ESP-32 cameras using the TensorFlow2 Object Detection API. The system achieves satisfactory accuracy and real-time processing capabilities, making it suitable for various practical applications. Overall, this thesis provides a foundation for further advancements and optimizations in the integration of object detection capabilities into small, low-power devices such as ESP-32 cameras and a crossroad to explore its applicability for other image-capturing and processing devices in industrial, automotive, and defense sectors of industry.

This project seeks to mitigate the reduced video quality from data compression due to bandwidth limits, which hinders the transmission of emotional information. The project applies selective compression to a prerecorded video to produce a modified video that compresses the background and preserves important emotional information. The effect of this selective compression was assessed through data collection of user emotional and visual response. The final end goal was to publish a paper summarizing the conclusions drawn from all of the lab data that was collected.

One answer to the lack of general knowledge for alternative energy and integration topics is seen in the workforce development content Laboratory of Energy and Power Solutions has generated for the past 6 years. LEAPS is a world-changing organization that provides both technical and business solutions in areas of grid modernization, workforce development, and global energy access that facilitates the global transition to a resilient, low-carbon economy. This paper will aim to explain the contributions of David Hobgood, an Arizona State University senior, to LEAPS workforce development content through the course of the Spring 2022 semester. This paper goes into detail on the process of completing this educational content, amplifies key aspect, and presents the results of a two week pilot that presented the generated content.

This study measure the effect of temperature on a neural network's ability to detect and classify solar panel faults. It's well known that temperature negatively affects the power output of solar panels. This has consequences on their output data and our ability to distinguish between conditions via machine learning.

This project examines the dynamics and design of control systems for a rocket in propulsive ascent and descent using a simplified model with motion constrained to a vertical plane. The governing differential equations are analyzed. They are then linearized, after which transfer functions are derived relating controllable input variables to controlled output variables. The effect of changes in various parameters as well as other aspects of the system are examined. Methods for controller design based on the derived transfer functions are discussed. This will include the discussion of control of the final descent and landing of the rocket. Lastly, there is a brief discussion about both the successes and limitations of the model analyzed.
