Stochastic stability and global bifurcations in gyroscopic mechanical systems
… parametrically excited by small periodic or stochastic perturbations is studied. In the case of random excitation, the almost-sure and moment asymptotic stability of two- and four-dimensional dynamical systems subject to small intensity noise is investigated. The almost-sure stability is …

Stochastic Stefan problems: existence, uniqueness, and modeling of market limit orders
In this thesis we study the effect of stochastic perturbations on moving boundary value PDE's with Stefan boundary conditions, or Stefan problems, and show the existence and uniqueness of the solutions to a number of stochastic equations of this kind. We also derive the space and time regularities …

Orbital Maneuvers and Interplanetary Trajectory Design via Reinforcement Learning
… presence of system uncertainties and unmodeled perturbations. Classical approaches to low-thrust trajectory design are predominantly grounded in optimal control theory, which relies on the availability of precise dynamical models and often requires problem-specific reformulation and solver …

Experimentally informed bottom-up model of yeast polarity suggests how single cells respond to chemical gradients
… representing polarity protein dynamics with a stochastic module representing vesicle trafficking on a plane with periodic boundary conditions. We found that the model could not quantitatively reproduce step-length and turning angle distributions, which suggested that some mechanisms driving …

Resilient operations of smart highways : platooning, ramp metering, and incident management
… under a broad range of disruptions, modeled as stochastic perturbations in highway capacity or traffic demand. In particular, we focus on three types of highway operations: vehicle platooning, ramp metering, and capacity-aware routing/demand management. Our approach relies on (i) modeling …
