Harley Hanes, NC State, Sensitivity and Identifiability Analysis of Boundary Penalties in a Galerkin Reduced Order Model.

SAS 1220

Galerkin reduced-order models (ROMs) approximate computational fluid simulations by reducing snapshot data to a basis of proper orthogonal decomposition (POD) modes and solving for modal coefficients with ordinary differential equations. Galerkin ROMs reduce computational cost and can approximate flows with alternate Reynolds numbers, while parametric reduced order models allow adjustment of other system parameters. However,…

Differential Equations and Nonlinear Analysis Seminar: Robin Neumayer, CMU, USA, Quantitative Faber-Krahn Inequalities and Applications

Zoom

Among all drum heads of a fixed area, a circular drum head produces the vibration of lowest frequency. The general dimensional analogue of this fact is the Faber-Krahn inequality: balls have the smallest principal Dirichlet eigenvalue among subsets of Euclidean space with a fixed volume. I will discuss new quantitative stability results for the Faber-Krahn…

Math Honors Presentation Session

Zoom

Differential Equations and Nonlinear Analysis Seminar: Francesca Bucci, Università degli Studi di Firenze, Italy, Riccati theory in the realm of PDE’s: state of the art and recent advances in the optimal control of evolution equations with memory

Zoom

The well-posedness of Riccati equations plays a central role in the study of the optimal control problem with quadratic functionals for linear partial differential equations (PDEs). Indeed, it allows the synthesis of the optimal control by solving the Riccati equation corresponding to the minimization problem, and then of the closed-loop equation. In this lecture I…

RESCHEDULED Thomas J. R. Hughes, University of Texas at Austin, Isogeometric Analysis: Mathematical and Engineering Perspectives

Zoom

The vision of Isogeometric Analysis (IGA) was first presented in a paper published October 1, 2005 . Since then it has become a focus of research within both the fields of Finite Element Analysis (FEA) and Computer Aided Design (CAD) and has become a mainstream analysis methodology and provided a new paradigm for geometric design…

Abhi Chowdhary, NC State, Infinite-dimensional Bayesian inversion for fault slip from surface measurements

SAS 1220

Given the inability to directly observe the conditions of a fault line, inversion of parameters describing them has been a subject of practical interest for the past couple of decades. To resolve this under a linear elasticity forward model, we consider Bayesian inference in the infinite dimensional setting given some surface displacement measurements, resulting in…

Explorations in Mathematical Modeling and Biofluids

SAS 1102

Speaker: Lisa Fauci, Professor of Mathematics, Tulane University Abstract: In the past decade, the study of the fluid dynamics of swimming organisms has flourished. My research has been centered on answering questions about biophysics using computational models of fluid flow: How do mammalian sperm penetrate the outer layer of an egg for successful fertilization?  How…
