On Enforcing Maximum Principles and Element-Wise Species Balance for Advective-Diffusive-Reactive Systems
… systems that provide accurate and physical solutions for a wide range of input data (e.g., Péclet and Damköhler numbers) and for complicated geometries. It is well-known that physical quantities like concentration of chemical species and the absolute temperature naturally attain non-negative …

CLASSIFICATION RESULTS FOR SEMILINEAR ELLIPTIC EQUATIONS
This thesis addresses classification problems of solutions to semilinear elliptic equations, with a particular focus on the study of symmetry and rigidity results. The thesis is divided into four chapters. In Chapter 1 we consider solutions to some semilinear elliptic equations on complete …

SCIENTIFIC MACHINE LEARNING METHODS FOR REACTIVE-TRANSPORT AND THERMAL-TRANSPORT PROBLEMS
… and cannot use the limited time history of solutions that might be available. The framework developed for reactive-transport problems overcomes this shortcoming to improve prediction accuracy using available time-history data. The framework uses convolutional neural networks for capturing …
