Surrogate Neural Networks for Efficient Simulation-based Trajectory Planning Optimization
… networks to reduce the computation time of simulation-based optimization of a reference trajectory. Simulation-based optimization is necessary when there is no analytical form of the system accessible, only input-output data that can be used to create a surrogate model of the simulation. …

Potential energy function development and dynamics of energy transfer and fragmentation for collisions of protonated peptide ions with organic surfaces
… used to prepare microarrays. Chemical dynamics simulations give near quantitative energy transfer probabilities for projectile ion collisions with surfaces as compared to experimental results, and there is substantial interest to extend this work to soft-landing. However, to model these …

Feasible Workspace for Robotic Fiber Placement
… to verify the feasibility of straight-line trajectory paths and to locate all valid towpreg segments in the workspace, with no focus on optimization. The algorithm is applied preliminary to a three-link planar arm; and a 6-dof Merlin robot is subsequently considered to verify the towpreg …

A Computational Framework for Dimensionally Reduced Particle Dynamics in Magnetic Nozzle Fields: An Adiabatic Invariant Approach
This thesis investigates a dimensional reduction strategy for modeling charged particle trajectories in electromagnetic fields representative of magnetic nozzle expansion regions. By employing Julia’s DifferentialEquations.jl and Python’s scientific libraries, particle trajectories are integrated …
