Amphibious emergency support operations involve rapidly changing information, high stress, and significant cognitive demands, which can make decision-making and situation awareness more difficult for operators. When interfaces are poorly designed, they can contribute to issues such as alarm flooding, confusion from incomplete information, and delayed responses, all of which increase operational risk during time-critical disaster situations. This study explores whether using generative AI to assist with interface design will improve performance (output quality and effort) and usability compared to a manual sketch mock-up. Participants were asked to design a dashboard interface to support disaster relief operations following a Category 5 …

Analytical And Numerical Solutions For The Hydrogen Atom, Kassidy Myers
Discovery Day - Daytona Beach
The Schrödinger equation is the foundational equation of non-relativistic quantum mechanics. The hydrogen atom is the simplest system for solving this equation, as it consists of only one proton and one electron. In this project, we work on the Schrödinger equation that models the spherically symmetric states of the hydrogen atom that depend only on the radial coordinate. We simplified and nondimensionalized the radial equation and solved the resulting equation using a power series (Frobenius) method. This approach revealed the physically meaningful solutions and led to quantized energy levels. In addition to finding the analytical solution, we numerically solve the …

Ai-Driven Scheduling Algorithms For Private Aviation, Tayan Benson, Jessica Buskey, Gabriel Camacho, Caitlyn A. Gabrinowitz
Discovery Day - Daytona Beach
Private aviation scheduling is complex and dynamic, requiring frequent aircraft repositioning based on demand and operational constraints, unlike fixed commercial airline schedules. As fleets grow beyond 300 aircraft, traditional deterministic methods become too slow, leading to the use of approaches such as genetic algorithms, but neural network-based methods have not seen in-depth exploration. This project models aircraft scheduling as a network, where airports and flights form a graph. It explores advanced AI methods, including graph neural networks and spatio-temporal graph neural networks (STGNNs), to capture both network structure and time constraints. The goal is to generate efficient daily schedules from …

MMRL-XMO Industrial Seminar
The evolution of lightweight biological structures for thermal regulation and structural stiffness, driven by multifunctionality requirements and ecological environments, provides a valuable blueprint for the development of lattice structures capable of both heat dissipation and mass reduction. Biological systems such as butterfly wing scales, weevil exoskeleton, toucan beak, pomelo peel, and other hierarchical porous morphologies exhibit highly optimized geometries that balance thermal management, mechanical performance, and lightweighting. Engineering lattice structures, including both strut-based and surface-based lattice topologies, offer analogous design strategies that can replicate these biological functionalities while remaining tailorable to not only the functionality and application-specific requirements but also …

Powder Metal Characterization For Additive Manufacturing, Paul Mort, Donovan Stumpf, Rajeshree Varma, Dina Khattab, Xiaoling Shen, Michael Titus, Michael Sealy, Jeff Jaworek, Jake Kim, Langdon Feltner
MMRL-XMO Industrial Seminar
Powder characterization is important for specification and qualification of powder feedstock materials used in powder-bed additive manufacturing. Characteristics include both distributed properties (i.e., particle morphology, size, shape, curvature distributions) as well as ensemble behavior including flow, spread-ability, and packing. Ensemble behavior is highly sensitive to boundary conditions in thin-layer processing, for example as required for additive manufacturing, thin-layer calendaring for dry-cathode processing, and many tribology-related applications. Particulate flow and packing are inherently multi-body ensemble processes; the distributed characteristics of particulates comprise said multi-body effects. Characterization of powder feedstock is important for manufacturing process control, resource efficiency, and product quality. This …
Generative Ai For Decision Making In The Manufacturing Systems, Xingyu Li
Generative Ai For Decision Making In The Manufacturing Systems, Xingyu Li
MMRL-XMO Industrial Seminar
Manufacturing systems increasingly demand real-time, multi-objective, and human-aligned decision-making that existing approaches cannot provide. In this study, we introduce the Generative Manufacturing System (GMS), a paradigm that reframes manufacturing decisions as samples from a learned conditional distribution, replacing inference-time search in the existing optimization-based approaches. Two instantiation examples are presented in manufacturing decision-making, including layout design and production scheduling, using domain-adapted diffusion models conditioned on operational constraints and human preferences. Experiments demonstrate 100% feasibility, near-zero objective matching error, and 25x decision making speed gain, establishing generative AI as a scalable, efficient, and human-centric decision-making engine for modern manufacturing systems.

A Generalized Real-Time Geometric Virtualization Of Material Removal Processes For A Factory Digital Twin Platform, Jongwoo Han, Chang Hyeon Mun, Martin Byung-Guk Jun, Hyung Wook Park
MMRL-XMO Industrial Seminar
As the transition toward autonomous smart factories and Cyber-Physical Production Systems (CPPS) accelerates, real-time digital twin implementation of manufacturing processes has emerged as a critical enabling technology. However, existing virtualization approaches present fundamental limitations: mesh-based Boolean methods are computationally infeasible for real-time processing due to their CPU-bound operations, while pure voxel-based methods suffer from staircase artifacts at geometric boundaries and exhibit exponentially increasing computational demands as resolution improves. To overcome these limitations, this paper proposes a GPU-accelerated real-time geometric virtualization method combining Signed Distance Field (SDF) with the Marching Cubes algorithm. The proposed method executes massively parallel SDF subtractive operations …

MMRL-XMO Industrial Seminar
Architected solids that combine high stiffness, strength, toughness, and ductility in one geometry are difficult to manufacture without specialised feedstocks or sequential consolidation. Two complementary architectures are built here from a single curvature-programmed building-block library of four constant-mean-curvature (CMC) shell topologies — Schwarz Primitive (SP), Schwarz Diamond (SD), Schoen's I-WP, and FRD — that share commensurate cubic facets and admit C0 /C1 /C2 continuity at every interface. Multi-objective hybridisation gives an open-cell metamaterial with specific axial stiffness E*/ρ* = 63.6 GPa·cm3 ·g-1 and specific peak compressive stress σpeak/ρ* = 416.9 MPa·cm3 ·g-1, exceeding the I-WP single family by 40% in …

An Automated Construction Framework For Immersive Digital Twins With Ground-Based Cad Pose Estimation, Huichan Park, Yuseop Sim, Byoungkwon Yoon, Asif Tanveer, Martin Byung-Guk Jun, Sang Won Lee
MMRL-XMO Industrial Seminar
This paper presents an automated workflow for constructing an immersive digital twin by combining multimodal field sensing, ground-based CAD-to-point-cloud registration, and physics engine-based scene generation. To reduce human intervention during digital twin construction, the proposed pipeline estimates machine poses by registering CAD-derived point clouds to a colorized point cloud map. Instead of relying on unconstrained six-degree-of-freedom point cloud registration algorithms, such as Iterative Closest Point (ICP) or TEASER++, the proposed method detects the ground plane, reduces the search space to planar translation and yaw, and applies coarse-to-fine slicing followed by 3-DoF planar ICP refinement. The method was evaluated using two …

However, many Wire Electrical Discharge Machining (Wire EDM) systems remain legacy machines with limited access to controller-level data, making non-invasive sensing approaches necessary. This study proposes a lightweight two-stage sound-based operational state monitoring framework using an Internal Sound Sensor (ISS) and a 1D convolutional neural network (CNN). The ISS, built around a stethoscope-inspired bell structure, captures machine-specific acoustic signatures while suppressing ambient machine-shop noise and spark-related acoustic interference. The proposed framework classifies machine states in two stages: Stage 1 identifies coarse states such as beep, …

Development Of A Cold Spray-Based Dry Manufacturing Process For Lfp Battery Cathode, Hayoung Jeong, Martin Byung-Guk Jun
Development Of A Cold Spray-Based Dry Manufacturing Process For Lfp Battery Cathode, Hayoung Jeong, Martin Byung-Guk Jun
MMRL-XMO Industrial Seminar
Conventional lithium-ion battery cathodes are typically fabricated through slurry-based processing, which requires organic solvents, coating, drying, and post-processing steps. Although this process is widely used, the use of toxic solvents such as N-methyl-2-pyrrolidone and the long drying process increases manufacturing complexity, energy consumption, and environmental burden. In this work, a cold spray-based solvent-free process was investigated as a one-step route for fabricating lithium iron phosphate cathode layers. A representative cathode composite powder consisting of lithium iron phosphate, carbon black, and polyvinylidene fluoride was prepared with a weight ratio of 10:1:1. To improve powder feeding behavior, 0.1 wt% fumed silica was …

Multi-Scale In-Situ Powder Stream Characterization For Laser Directed Energy Deposition, Guang Yang, Clara Mock, Salil Bapat, Ajay Malshe
MMRL-XMO Industrial Seminar
Powder stream quality in laser directed energy deposition (L-DED) is a critical determinant of deposition consistency and final part quality, yet it remains largely uncharacterized in real-time during operation. This paper presents a dual-scale, vision-based in-situ characterization framework that addresses powder stream monitoring at two complementary levels: macro-scale flow quality assessment for real-time process monitoring and micro-scale particle tracking for digital twin data acquisition. Both scales are implemented on a single high-speed camera reconfigured between two resolution and frame-rate settings, eliminating the need for dedicated multi-camera infrastructure. At the macro scale, an OpenCV-based image processing pipeline operating at 1280 × …

Controllable Failure In 3d Printed Carbon Fiber Petg Using Programmable Cooling Conditions, Anna Keim, Monique Mcclain
MMRL-XMO Industrial Seminar
The tensile properties of 3D printed specimens using fused filament fabrication (FFF) are the subject of extensive research. Forced convection from print cooling fans has been shown to have a measurable effect on print quality and tensile performance because the cooling rate of the polymer strongly controls interlayer adhesion. Print fan speeds are typically kept constant throughout a print, but changing the fan cooling throughout a print has the potential to locally tune interlayer strength and therefore, the location of break. This work shows the effect of selectively cooling printed regions, with the goal of repeatably inducing failure in these …

Large Language Models (LLMs) have recently shown strong performance across various domains, including manufacturing, where they are increasingly used with multi-agent systems for semi-autonomous tasks such as real-time machine monitoring and operator support. However, their reliability remains a concern due to hallucination, where outputs may appear plausible but contain incorrect or inconsistent information. To address this issue, this study proposes a semantic evaluation methodology for assessing the reliability of LLM-generated content in machining environments. The approach is based on the embedding model BGE-M3 and focuses on capturing semantic consistency between machine observations and LLM-generated operational recommendations by comparing them against …

High-temperature thermal barrier systems require a graded architecture that transitions from a metallic substrate to a ceramic top coat to mitigate damage caused by mismatches in coefficients of thermal expansion (CTE). This study presents a convergent manufacturing strategy that integrates twisted wire gas tungsten arc (GTA) surfacing with cold sintering (CS), followed by CO₂ laser sintering, to fabricate a robust thermal barrier. High entropy alloy (HEA) bond coats with Al-Cr-Fe-Ni-based compositions were deposited onto Inconel 625 substrates using semi-automatically twisted commercial welding wires (Inconel 625, SS308Lsi, and Al ER4043) via GTA surfacing, resulting in HEA layers predominantly composed of >60 …
