Mathematics Colloquium: Fernando Guevara Vasquez (University of Utah)**Thursday, May 3 2012 at 3:30 PM**
Mathematics Colloquium, featuring Fernando Guevara Vasquez (University of Utah), titled, "Active exterior cloaking for the Helmholtz equation," will occur May 3 at 3:30 p.m. in TLC 032.
ABSTRACT: We present a way of using active sources to hide objects from a known incident field. The active sources cancel out the incident field in a region while having a small far field. Since very little waves ...

Mathematics Colloquium: Jodi Mead (Boise State University)**Thursday, April 19 2012 at 3:30 PM**
Mathematics Colloquium, with Jodi Mead (Boise State University), titled "Inverse Problems and Uncertainty Quantification," will occur April 19 at 3:30 p.m. in TLC 032.
ABSTRACT: Combining physical or mathematical models with observational data often results in an ill-posed inverse problem. Regularization is typically used to solve ill-posed problems, and it can be viewed as adding statistical or...
