A Posteriori Error Estimation for Finite Element Methods and Iterative Linear Solvers
(Dr. ingeniøravhandling, 0809-103X; 2001:98, Doctoral thesis, 2001)This thesis addresses a posteriori error estimation for finite element methods and iterative linear solvers. Adaptive finite element methods have gained a lot of popularity over the last decades due to their ability to ... -
Depth consistent pp and ps seismic angle tomography
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:18, Doctoral thesis, 2004)This thesis addressed the problem of finding background models yielding depth consistent migrated PP and PS images, i.e. geologically equivalent reflectors should be imaged at the same depth in the two images. The tomographic ... -
Modes of description and indicators of formalism in students' descriptions of eigenvectors
(Peer reviewed; Journal article, 2023)In the study presented in this paper, we investigate students' concepts of eigenvectors in an early stage of their education on linear algebra. The different descriptions used by the students for eigenvectors are analysed ... -
Numerical Solution og Coupled CFD Problems by the Domain Decomposition Method
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:102, Doctoral thesis, 2004)In this thesis we look at the efficient numerical solution of two complex multi-physics problems which both have very important applications. The first problem is related to the numerical simulation of extrusion of aluminium. ... -
On Eigen-decompositions and Adaptivity of Markov Chains
(Dr. ingeniøravhandling, 0809-103X; 2003:102, Doctoral thesis, 2003)Part I and Part III-V concern Markov chain Monte Carlo and in particular those algorithms related to the Metropolis-Hastings algorithm. In Part I-II we apply an eigendecomposition of the transition probability matrix. The ... -
