Application of a Bayesian Choice Model on Monthly Client Data - at SpareBank 1 SMN
(Master thesis, 2015)This paper applies a Bayesian Dynamic Choice model on monthly collected client data at SpareBank 1 SMN in order to examine the rate at which they enter or leave Life- and Danage-insurance. The main goal of the paper is ... -
Application of Nek5000 to dispersion simulations
(Master thesis, 2016)Simulations of turbulent flow and gas dispersion are performed using Nek5000, with and without a subgrid-scale model. The results are compared with data from wind- tunnel experiments and previously performed simulations ... -
Application of the wavelet transform for analysis of ultrasound images
(Master thesis, 2008)In this master thesis we analyse medical ultrasound images using the wavelet transform. Mathematical theory is introduced for both one-dimensional and two-dimensional functions. Three edge detectors based on the mathematical ... -

Applications of p-adic Numbers to well understood Quantum Mechanics: With a focus on Weyl Systems and the Harmonic Oscillator
(Master thesis, 2012)In this thesis we look at how it is possible to construct models in quantum mechanics by using p-adic numbers. First we look closely at different quantum mechanical models using the real numbers, as it is necessary to ... -

(Master thesis, 2016)Applications of Paillier s crypto system to electronic voting. -
Applications of splitting Methods and exponential Integrators to an electro-chemical Heart Cell Model
(Master thesis, 2007)In this thesis we discuss how a system of ordinary differential equations (ODE) describing electro-chemical processes in a heart cell can be solved by numerical methods. The system is stiff, and explicit numerical solvers ... -
Applying hybrid methods to reduce nonphysical cycles in the flux field
(Master thesis, 2012)In this thesis we present the theoretical background for the two-point flux-approximation method; (TPFA), mimetic discretisation methods, and the multipoint flux approximation method; (MPFA). Theoretical arguments concerning ... -
Applying quantum harmonic analysis to Convolutional Neural Networks
(Master thesis, 2023)I løpet av de siste fem årene har rammeverket for tid-frekvensanalyse blitt komplementert med begreper som blandet tilstandslokalisering operatorer, Cohen-klassen til en operator og dens akkumulerte versjon. Inspirasjonen ... -
Approximate Bayesian Inference Based on Expected Evaluations
(Peer reviewed; Journal article, 2023)Approximate Bayesian computing (ABC) and Bayesian Synthetic likelihood (BSL) are two popular families of methods to evaluate the posterior distribution when the likelihood function is not available or tractable. For existing ... -
Approximate Bayesian Inference for Latent Gaussian Models
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:214, Doctoral thesis, 2007)This thesis consists of five papers, presented in chronological order. Their content is summarised in this section. Paper I introduces the approximation tool for latent GMRF models and discusses, in particular, the ... -
Approximate Bayesian inference for spatial econometrics models
(Journal article; Peer reviewed, 2014)In this paper we explore the use of the Integrated Laplace Approximation (INLA) for Bayesian inference in some widely used models in Spatial Econometrics. Bayesian inference often relies on computationally intensive ... -

Approximate elements for set optimization problems with respect to variable domination structures
(Peer reviewed; Journal article, 2022)We consider set optimization problems governed by the upper set less relation introduced by Kuroiwa. We extend some known results from the literature to a setting that includes (a) variable domination structures and (b) ... -
Approximate Filtering Approaches for Switching Linear Dynamical Systems
(Master thesis, 2022)«State-observation model» er et dynamisk Bayesiansk nettverk (DBN) som inneholder to mengder stokastiske variabler som utvikler seg over tid; en skjult mengde og en observert mengde. De mest kjente «state-observation» ... -
Approximate marginal inference in binary Markov random fields using a mean squared error energy approximation and the junction tree algorithm
(Master thesis, 2016)In this thesis, we use a mean squared error energy approximation for edge deletion in order to make performing inference in Markov random fields using the junction tree algorithm tractable, and by that develop an approximate ... -
Approximate recursive algorithm for finding MAP of binary Markov random fields
(Master thesis, 2010)The purpose of this study was to develop a recursive algorithm for computing a maximum a posteriori (MAP) estimate of a binary Markov random field (MRF) by using the MAP-MRF framework. We also discuss how to include an ... -
Approximate recursive calculations of discrete Markov random fields
(Master thesis, 2010)In this thesis we present an approximate recursive algorithm for calculations of discrete Markov random fields defined on graphs. We write the probability distribution of a Markov random field as a function of interaction ... -
Approximation numbers of composition operators on H^p spaces of Dirichlet series
(Journal article; Peer reviewed, 2016)By a theorem of the first named author, $\varphi $ generates a bounded composition operator on the Hardy space ${\mathscr{H}}^p$of Dirichlet series $(1\le p<\infty )$ only if $\varphi (s)=c_0 s+\psi (s)$, where $c_0$ is a ... -
