Oct 22, 11:25am to 12:40pm
Applied Mathematics - Seminar - E1 242
Abstract: This presentation includes two models that independently analyze the morphological stability of tumor spheroids. The interface is being modeled as an elastic membrane which has a bending rigidity dependent on the curvature. An investigation is being performed on how various physical... read more

Oct 20, 4:40pm to 5:55pm
Applied Mathematics - Colloquia - E1 104
Abstract: In numerical computations and engineering simulations, solving large dense linear systems is usually the major cost. Examples include discretized integral equations, Schur complements in direct factorizations of sparse matrices, radial basis function interpolations, spectral... read more

Applied Mathematics - Seminar - E1 242
Abstract: With SPH there are generally two ways to model the surface tension effect: one is based on a macroscopic surface tension model; the other one uses microscopic inter-phase potentials. The approach using a macroscopic surface-tension model usually defines a color function,... read more

Applied Mathematics - Seminar - E1 242
Abstract:  The Laplace operator appears in the Navier-Stokes equations, the geophysical flow equations, and the equation for substance transport in fluids.  It comes out so often that we at times forget its origin, let alone its connection with modern stochastic analysis, stochastic... read more

Applied Mathematics & Data Science - Seminar - SB 220
Data Science is rapidly becoming a mainstream and mission critical function across enterprises. What does it mean from a practitioners point of view – what business value and return on investment are expected, what types of problems are encountered in the field, what daily tasks are typically... read more

Oct 1, 11:25am to 12:40pm
Applied Mathematics - Seminar - E1 242
Abstract: Many physical problems involve moving interfaces. We review a curvature weakening model. We consider the interface to be an elastic membrane with a bending rigidity , a function of the local curvature. And we can also use a boundary integral method to solve the problem numerically.... read more

Applied Mathematics - Colloquia - E1 104
Sparse matrix algorithms lie in the intersection of graph theory and numerical linear algebra, and are a key component of high-performance combinatorial scientific computing. This talk highlights four of my contributions in this domain, ranging from theory and algorithms to reliable mathematical... read more

Yan-Feng Guo
Sep 24, 11:25am to 12:40pm
Applied Mathematics - Seminar - E1 242
Abstract: The existence of a compact random attractor for the stochastic complex Ginzburg-Landau equation with multiplicative noise has been investigated on unbounded domain. The solutions are considered in suitable spaces with weights. According to crucial properties of Ornstein-Uhlenbeck process... read more

Sep 22, 4:40pm to 5:55pm
Applied Mathematics - Colloquia - E1 104
Abstract: Contemporary statistical procedures are making inroads into a diverse range of applications in the natural sciences and engineering. However it is difficult to use those procedures "off-the-shelf" because they have to be properly tuned to the particular application.  ... read more

Applied Mathematics & Data Science - Seminar - E1 124
Researchers in medicine and the social sciences attempt to identify and document causal relationships. Those not fortunate enough to be able to design and implement randomized control trials must resort to observational studies. To preserve the ability to make causal inferences outside the... read more
