New FOSLS Formulation of Nonlinear Stokes Flow for Glaciers
07 Feb 2016 | | Contributor(s):: Jeffrey Allen
This talk describes two First-order System Least-squares (FOSLS) formulations of the nonlinear Stokes flow used to model glaciers and ice sheets. The first is a Stress formulation and the second a Stress-Vorticity formulation. Both use fluidity, which is the reciprocal of viscosity and avoid the...
Multilevel Markov Chain Monte Carlo for Uncertainty Quantification in Subsurface Flow
04 Feb 2016 | | Contributor(s):: Christian Ketelsen
The multilevel Monte Carlo method has been shown to be an effective variance reduction technique for quantifying uncertainty in subsurface flow simulations when the random conductivity field can be represented by a simple prior distribution. In state-of-the-art subsurface simulation the...
[Illinois] Fluidic Nanoprobes for In Vitro Single Cell Studies
17 Dec 2013 | | Contributor(s):: Horatio Espinosa
A robust method for single cell access to deliver genes and small molecules to primary and sensitive cells is needed to advance the state-of-the-art in personalized medicine and therapeutics. To realize this goal, a microfluidic chip, so-called nanofountain probes (NFP), has been developed for...
