Get Moving with Quad in Motion
The third annual Quad in Motion will take place from 8 a.m. to 4 p.m. Wednesday, Sept. 13, on the Quad. The Office of Health Promotion and Wellness wants all 6000+ employees to keep the Quad in Motion by walking or running for at least 30 minutes that day. Employees are asked to sign up
Applied Math Seminar – Xu Zhang, Mississippi State University
228 Gordon Palmer Hall Tuscaloosa, AL, United StatesTitle: Immersed Finite Element Methods for Interface Problems Basic idea, Development, Analysis, and Applications Abstract: Simulating a multi-scale/multi-physics phenomenon often involves a domain consisting of different materials. This often leads to the so-called interface problems of partial differential equations. Classical finite elements methods can solve interface problems satisfactorily if the mesh is aligned with interfaces; otherwise the
Applied Math Seminar – Mojdeh Rasoulzadeh, University of Alabama
228 Gordon Palmer Hall Tuscaloosa, AL, United StatesTitle: Effective models of flow in highly heterogeneous fractured/vuggy porous media Abstract: The presence of vugs and fractures in porous media can significantly affect pressure and flow behavior of a fluid. In this talk, I will present the effective models of flow in a porous medium including multi-scale fractures and several vuggs of various
Analysis Seminar – Michael Dabkowski (Lawrence Technological University)
227 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United StatesTitle: Global Stability of a Class of Nonlinear PDE with a Nonlocal Term Abstract: We will establish global asymptotic stability results for a class of non-linear PDE which arise in approximations of models of particle coarsening. These PDE must satisfy a conservation of mass constraint which induces a nonlocal term into the equation. Our method

Analysis Seminar – David Cruz-Uribe, University of Alabama
Title: A gentle introduction to Rubio de Francia extrapolation Abstract
Applied Math Seminar – Brendan Ames, University of Alabama
228 Gordon Palmer Hall Tuscaloosa, AL, United StatesTitle: Semidefinite relaxation of the clustering problem and first-order methods for their solution Abstract: I will discuss a novel relaxation approach for the graph clustering problem. Although intractable in worst-case, much recent research has established that clusters can be recovered if the underlying network or data is well-behaved. In particular, I will provide conditions on
Applied Math Seminar – Wei Zhu, University of Alabama
228 Gordon Palmer Hall Tuscaloosa, AL, United StatesTitle: New augmented Lagrangian method for a curvature dependent segmentation model Abstract: Augmented Lagrangian methods (ALMs) have proved to be successful for the minimization of curvature dependent functionals in image processing. However, those ALM based algorithms often suffer from choosing appropriate penalty parameters in the numerical implementation. In this talk, we will discuss our recent
Analysis Seminar – Kabe Moen, University of Alabama
227 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United StatesTitle: Commutators and weighted norm inequalities Abstract: We will review the theory of commutators and BMO functions. As an application of the theory of weighted norm inequalities we will show that the commutator of an operator that satisfies certain weighted norm inequalities is bounded on L^p. We also show show a converse to this result.
Colloquium – Zhimin Zhang, Wayne State University
346 Gordon Palmer Hall 505 Hackberry Lane, Tuscaloosa, AL, United StatesTopic: Polynomial Preserving Recovery for Gradient and Hessian Abstract: Post-processing techniques are important in scientific and engineering computation. One of such technique, Superconvergent Patch Recovery (SPR) proposed by Zienkiewicz-Zhu in 1992, has been widely used in finite element commercial software packages such as Abaqus, ANSYS, Diffpack, etc.; another one, Polynomial Preserving Recovery (PPR) has been
