Pulsed Optical Injection Steering in Multistable Semiconductor Laser Arrays under Correlated Noise
Max M. Chumley, Herbert G. Winful
We demonstrate robust programmable state preparation in small Vertical Cavity Surface Emitting Laser (VCSEL) arrays with optical feedback using transient optical injection in the f…
Dynamical System Parameter Path Optimization using Persistent Homology
Max M. Chumley, Firas A. Khasawneh
Nonlinear dynamical systems are complex and typically only simple systems can be analytically studied. In applications, these systems are usually defined with a set of tunable para…
Hall Effect Thruster Forecasting using a Topological Approach for Data Assimilation
Max M. Chumley, Firas A. Khasawneh
Hall Effect Thrusters (HETs) are electric thrusters that eject heavy ionized gas particles from the spacecraft to generate thrust. Although traditionally they were used for station…
Topological Approach for Data Assimilation
Max M. Chumley, Firas A. Khasawneh
Many dynamical systems are difficult or impossible to model using high fidelity physics based models. Consequently, researchers are relying more on data driven models to make predi…
A Nonlinear Delay Model for Metabolic Oscillations in Yeast Cells
Max M. Chumley, Firas A. Khasawneh, Andreas Otto +1
We introduce two time-delay models of metabolic oscillations in yeast cells. Our model tests a hypothesis that the oscillations occur as multiple pathways share a limited resource…
Pattern Characterization Using Topological Data Analysis: Application to Piezo Vibration Striking Treatment
Max M. Chumley, Melih C. Yesilli, Jisheng Chen +2
Quantifying patterns in visual or tactile textures provides important information about the process or phenomena that generated these patterns. In manufacturing, these patterns can…
Topological Measures for Pattern quantification of Impact Centers in Piezo Vibration Striking Treatment (PVST)
Melih C. Yesilli, Max M. Chumley, Jisheng Chen +2
Surface texture influences wear and tribological properties of manufactured parts, and it plays a critical role in end-user products. Therefore, quantifying the order or structure…
Delay Parameter Selection in Permutation Entropy Using Topological Data Analysis
Audun D. Myers, Max M. Chumley, Firas A. Khasawneh
Permutation Entropy (PE) is a powerful tool for quantifying the complexity of a signal which includes measuring the regularity of a time series. Additionally, outside of entropy an…
