- ontrolling oscillations in high-order accurate methods through neural networksWhile discontinuous Galerkin methods have proven themselves to be powerful computational methods, capable of accurately solving a variety of PDE's, the combination of high
- Neuroendocrine stress response and PTSDThe hypothalamic-pituitary-adrenal (HPA) axis is a neuroendocrine system that regulates numerous physiological processes. Disruptions are correlated with stress-related diseases such as PTSD and major
- A touch of non-linearity in fluid fields: where spheres 鈥渢hink鈥 collectively and swim togetherFrom crawling cells to orca whales, swimming in nature occurs at different scales. The study of swimming across length scales can shed light onto
- Practical and Theoretical Questions in Network Synchronization: Optimization and Control Collective behavior in large ensembles of network-coupled dynamical systems remains an active area of research in the nonlinear dynamics and networks
- Feedback-based online algorithms for time-varying network optimizationThe talk focuses on the synthesis and analysis of online algorithmic solutions to control networked systems based on performance objectives and engineering constraints that may
- Finite-Horizon Approximate Linear Programs for an Infinite-Horizon Revenue Management ProblemApproximate linear programs have been used extensively to approximately solve stochastic dynamic programs that suffer from the well-known curse of
- Inference on Winners Many empirical questions can be cast as inference on a parameter selected through optimization. For example, researchers may be interested in the effectiveness of the best policy found in a randomized trial, or the
- Spectral Problems in Inverse Scattering for Inhomogeneous MediaThe inverse scattering problem for inhomogeneous (possibly anisotropic) media amounts to solving a nonlinear ill-posed equation, thus presenting difficulties in arriving at a solution.
- Granular flow: Particle Size Segregation and New Constitutive LawsThe segregation of particles of different sizes can be achieved by vibration or by shear flow. I describe a nonlinear conservation law that captures the main features of segregation
- Differential imaging of evolution in elastic backgrounds with unknown microstructureMajor components of nuclear power plants e.g., reactors, fuel cells and containment vessels are comprised of highly heterogeneous composites that (a) their topology
