Globally Convergent Numerical Methods for Some Coefficient Inverse Problems
Found in: Computing in Science and Engineering
By Jianguo Xin, Larisa Beilina, Michael Klibanov
Issue Date:September 2010
pp. 64-77
How can we differentiate between an underground stone and a landmine? A class of new numerical methods aims to address this question using globally convergent—rather than locally convergent—algorithms for coefficient inverse problems....
Implementation of hierarchical bases in FEMLAB for simplicial elements
Found in: ACM Transactions on Mathematical Software (TOMS)
By Jianguo Xin, Joseph E. Flaherty, Katia Pinchedez
Issue Date:June 2005
pp. 187-200
We present the implementation of well-conditioned hierarchical bases for one-dimensional, triangular and tetrahedral elements in finite element FEMLAB software. Using the domain mesh information provided by FEMLAB, we found an easy way to maintain the cont...
