High order volume preserving integrators for three kinds of divergence-free vector fields via commutators
(Huiyan Xue, 2013)
In this paper, we focus on construction of high order volume preserving integrators for divergence-free vector fields of the monomial basis, exponential basis and tensor product of the monomial and exponential basis. We ...
A unified multilevel framework of upscaling and domain decomposition
(International Center for Numerical Methods in Engineering (CIMNE), 2010)
We consider multiscale preconditioners for a class of mass-conservative domain-decomposition (MCDD) methods. For the application of reservoir simulation, we need to solve large linear systems, arising from finite-volume ...
Compositional reservoir simulation with emphasis on the IMPSAT formulation
(The University of Bergen, 2006-04-07)
New examples of curves with a one-dimensional family of pencils of minimal degree
We give a geometric construction of sub-linear systems on a K3 surface consisting of smooth curves C with infinitely many g1 gon(C)’s.
Mål for asymmetri og kurtose
(The University of Bergen, 2010-04-13)
Critchley og Jones (2008) innfører nye mål for asymmetri og kurtose. Denne oppgåva drøftar måla som teoretiske mål og med tanke på estimering.
Robust Multiscale Control-volume Methods for Reservoir Simulation
(The University of Bergen, 2012-04-30)
Reversible Jump Markov Chain Monte Carlo: Some Theory and Applications
(The University of Bergen, 2014-03-10)
The history of MCMC, theories of Bayesian thinking and model choice, the Accept- Reject-algorithm, Markov chains, the Metropolis- Hastings-algorithm and the reversible jump MCMC are explained. Then the reversible ...
Oribatid mites in a changing world
(The University of Bergen, 2011-12-09)
The main scope of this thesis is to illustrate the validity of oribatid mites as tools for palaeoecological reconstructions. Palaeoecology studies the responses of past organisms to past environmental changes. This ...
Ruin probability and optimal dividend policy for models with investment
(The University of Bergen, 2012-11-06)
<p>In most countries the authorities impose capital requirements on insurance companies in order to avoid the adverse consequences to society when insurance companies default on claims. Since holding capital is costly, ...
Multiscale mass conservative domain decomposition preconditioners for elliptic problems on irregular grids
Multiscale methods can in many cases be viewed as special types of domain decomposition preconditioners. The localisation approximations introduced within the multiscale framework are dependent upon both the heterogeneity ...
