Multi-Disciplinary Analysis Surrogate Based On Twin-Generator Generative Adversarial Networks For Electric Drone, Samuel Sisk Apr 2023

Multi-Disciplinary Analysis Surrogate Based On Twin-Generator Generative Adversarial Networks For Electric Drone, Samuel Sisk

NASA-Missouri Space Grant Consortium

Multi-Disciplinary Analysis and Optimization (MDAO) plays an important role in the future of aviation, especially relating to Urban Air Mobility (UAM). MDAO for UAM effectively quantifies and maximizes system performance and safety while minimizing cost or consumption. Electric drone takeoff trajectory design aims to minimize energy consumption while fulfilling acceleration and other constraints to keep passengers comfortable. Conventional simulation-based MDAO is computationally expensive due to repeatedly evaluating physics-based models while naïvely constructing machine learning predictive models, also known as surrogate models, do not scale well with large-scale problems due to the “curse of dimensionality”. A twin-generator generative adversarial networks (Twin-GAN) …

Lunar In-Situ Aluminum Production Through Molten Salt Electrolysis (Lisap-Mse), Jacob Ortega, Jeffrey D. Smith, Fateme Rezaei, David Bayless, William P. Schonberg, Daniel S. Stutts, Daoru Frank Han

NASA-Missouri Space Grant Consortium

The goal of Artemis is to establish a sustained presence on the Moon. To achieve so, numerous resources are necessary. The Moon contains several essential elements needed to sustain human presence. Most of those elements are trapped in the form of minerals. To refine those minerals into useful materials, reduction methods are needed. Most reduction methods on Earth require large amounts of mass and power which is unrealistic for early stages of building a lunar base. To solve this problem, we are developing a concept of Lunar In-Situ Aluminum Production through Molten Salt Electrolysis (LISAP-MSE).

The LISAP-MSE project, if successful, …


3d Reconstruction Of Syndactylized Hand In Autodesk Recap Photo With Arduino, Caleb E. Scheideger Apr 2023

3d Reconstruction Of Syndactylized Hand In Autodesk Recap Photo With Arduino, Caleb E. Scheideger

ONU Student Research Colloquium

Syndactyly is one of the most common congenital malformations of the hand and is a result of a failed separation of adjacent digits. These digits are common among congenital limb malformations that affect 1 out of 2,000-3,000 people at birth. A reconstructive surgery would be needed to separate the digital skin, reconstruct the web space between fingers, and cover the separated digits with soft tissues. Finding the optimal shape and size for a dorsal flap in the web commissure reconstruction is important to avoid web creep. Conducting a numerical study with known mechanical properties, such as Young’s Modulus of the …

Promoting Skills In Children And Teens With Autism Spectrum Disorder Through Play And Steam, Meaghan Mcleod Mozingo, Krzysztof J. Rechowicz Apr 2023

Promoting Skills In Children And Teens With Autism Spectrum Disorder Through Play And Steam, Meaghan Mcleod Mozingo, Krzysztof J. Rechowicz

Modeling, Simulation and Visualization Student Capstone Conference

Individuals with autism spectrum disorder (ASD) have a low employment rate. This is caused by a lack of support from employment resources and the negative stigma associated with common characteristics associated with ASD. With limited career-building activities and events, it is difficult for individuals with ASD to identify their skills, strengths, and career opportunities. Parental support is crucial when seeking employment opportunities for their children. Through the use of play, children with ASD engaged and explored their skills with science, technology, engineering, arts, and math-centered activities. This paper highlights the events and shows the proposed redesign for an additional workshop.

The Legacy Of Colonization And Civil Societies In South Africa, Erika Frydenlund, Melissa Miller-Felton, Bolu Ayankojo

Modeling, Simulation and Visualization Student Capstone Conference

This research analyzes the unique ways that civil societies operate in Sub-Saharan Africa in the context of post-apartheid Cape Town, South Africa. Decades after the demise of apartheid, remnants of inequality remain without the promise of actionable change. We used a computational modeling approach to understand the dynamics of migrants in the receiving community as derived from qualitative interviews conducted with 24 stakeholders in Cape Town, South Africa between 2020 and 2021. Our findings show that the presence of NGOs can promote access to resources and reduce xenophobia if they can have the right influence on government policies.
