This thesis presents a comprehensive investigation into the design of roller coasters. The study includes an overview of various roller coaster types, cart design, brake design, lift hill and launch design, support design, and roller coaster safety. Utilizing No Limits 2 to design the layout and CAD software for component design, a scale model roller coaster was designed. The physics of the roller coaster and its structures were analyzed and a scale model was produced. Afterward, an accelerometer was used to collect G force data as the cart moved along the track. However, the collected data differed from the expected results, as the launch speed was higher than predicted due to more friction than anticipated. As a result, further optimization of the design and models used to design the scale model roller coasters is necessary.

This paper documents the design, analysis, and construction of a towing tank suitable for experimental studies within a Reynolds number less than approximately 500,000, for test models of varying shape. The design and manufacturing of a towing tank provides Arizona State University with laboratory equipment for experimental fluid mechanics. The design consists of a 3-meter-long, 0.5-meter-wide, and 0.8-meter-high cast acrylic tank with aluminum welded-frame supports. There is a pulling mechanism consisting of a belt drive and linear rail guide system that will be positioned on top of the tank. The pulling mechanism is currently in the prototype development stage. The prototype serves as a proof of concept for the final design, as data has been collected and analyzed using MATLAB, resolving the drag force of a submerged test model. This paper demonstrates the design process, prototype development, and construction of the towing tank. The original goal of this research was to answer questions about optimization of a swimmer’s technique by providing strong experimental results and deep analysis of the factors affecting performance. However, there were tasks along the way that shifted the focus from experimentation and analysis to design and manufacturing.

This honors thesis proposes a sustainable solution for providing off-grid solar energy to rural communities lacking grid energy infrastructure. The proposed design emphasizes sustainability, low cost, reliability, and ease of maintenance and manufacturing. The report compares pre-built solar systems currently available for purchase with the proposed design. The project includes a user manual draft to ensure long-term sustainability and troubleshooting. Additionally, there is a detailed engineering design for a battery storage solution, electrical component design, and solar panel mounting system. A rural community in northern Arizona serves as an example for the project completed in collaboration with ASU's EPICS program and EWB Chapter. The project is ongoing, with future work to optimize and improve the proposed system design.

The study tested the parameterized neural ordinary differential equation (PNODE) framework with a physical system exhibiting only advective phenomenon. Existing deep learning methods have difficulty learning multiple dynamic, continuous time processes. PNODE encodes the input data and initial parameter into a set of reduced states within the latent space. Then the reduced states are fitted to a system of ordinary differential equations. The outputs from the model are then decoded back to the data space for a desired input parameter and time. The application of the PNODE formalism to different types of physical systems is important to test the methods robustness. The linear advection data was generated through a high-fidelity numerical tool for multiple velocity parameters. The PNODE code was modified for the advection dataset, whose temporal domain and spatial discretization varied from the original study configuration. The L2 norm between the reconstruction and surrogate model and the reconstruction plots were used to analyze the PNODE model performance. The model reconstructions presented mixed results. For a temporal domain of 20-time units, where multiple advection cycles were completed for each advection speed, the reconstructions did not agree with the surrogate model. For a reduced temporal domain of 5-time units, the reconstructions and surrogate models were in close agreement. Near the end of the temporal domain, deviations occurred likely resulting from the accumulation of numerical errors. Note, over the 5-time units, smaller advection speed parameters were unable to complete a cycle. The behavior for the 20-time units highlighted potential issues with imbalanced datasets and repeated features. The 5-time unit model illustrates PNODEs adaptability to this class of problems when the dataset is better posed.

A new uniaxial testing apparatus that has been proposed takes advantage of less costly methods such as 3D printing of tensile fixtures and image reference markers for accurate data acquisition. The purpose of this research is to find methods to improve the resolution, accuracy, and repeatability of this newly designed testing apparatus. The first phase of the research involved building a program that optimized the testing apparatus design depending on the sample being tested. It was found that the design program allowed for quick modifications on the apparatus in order to test a wide variety of samples. The second phase of research was conducted using Finite Elements to determine which sample geometry reduced the impact of misalignment error most. It found that a previously proposed design by Dr. Wonmo Kang when combined with the testing apparatus lead to a large reduction in misalignment errors.
