Viskoelastisen mallin sovittaminen kostean paperin jännitysmittauksiin
(2018)
Kostean paperin jännitys riippuu venymän lisäksi ajasta, jolloin jännityksen sanotaan olevan viskoelastista. Tässä kandidaatintutkielmassa sovitettiin viskoelastinen malli kostealle paperille tehtyihin jännitysmittauksii ...
Hamiltonian Monte Carlo and non-Gaussian random field priors for x-ray tomography
(2019)
Solving a statistical inverse problem requires selecting an appropriate prior distribution to model the phenomenon in question and using numerical algorithms, like MCMC methods, to calculate the estimates in practise. ...
On numerical implementation of α-stable priors in Bayesian inversion
(Lappeenranta-Lahti University of Technology LUT, 2023-12-08)
In this thesis, we introduce numerical approximations of Levy α-stable random field priors for Bayesian inversion. The α-stable processes are well-studied in stochastic process literature, and they can be potentially ...
