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
Title:Â Immersed Finite Element Methods for Interface Problems Basic idea, Development, Analysis, and Applications Abstract:Â 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
Title: 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
Title: 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

Title: 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
