Research
My research interests center on integrating dynamics, control, and machine learning to push the boundaries of robotics and, where applicable, tackle challenges across a range of scientific disciplines.
Stability Prediction via Parameter Estimation from Milling Time Series
James D. Turner,
Sam A. Moore,
Brian P. Mann
Journal of Sound and Vibration, 2023 paper
This paper introduces an approach to milling stability analysis whereby the vibration behavior of a milling tool during
cutting is used to directly obtain the parameters of a delay differential equation model of milling.
A Model-Free Sampling Method for Basins of Attraction Using Hybrid Active Learning

Communications in Nonlinear Science and Numerical Simulation. 2022 paper project page
This work introduces a model-free sampling method for basins of attraction. The proposed method is based upon hybrid active learning and is designed to find and
label the “informative” samples, which efficiently determine the boundary of basins of attraction.
Supervised Learning for Abrupt Change Detection in a Driven Eccentric Wheel
Sam A. Moore,
Dean Culver,
Brian P. Mann
International Modal Analysis Conference, 2022
paper
This paper seeks to explore and compare supervised learning methods for phase identification
(i.e., roll, slip, and hop) in simulated data from a driven eccentric wheel as a prototypical non-smooth system.
The Eccentric Disk and Its Eccentric behavior
Sam A. Moore,
Dean Culver,
Brian P. Mann
European Journal of Physics, 2021
paper
An eccentric disk has a non-constant normal force and therefore has four distinct phases of motion: oscillations about a stable equilibrium, roll without slip, roll with slip, and hop.
In this work, the system is analytically modeled using an augmented Lagrangian formulation, solved with numerical integration, and experimentally realized.
