Mulige aktive forurensningskilder i havneområdet i Trondheim
(Master thesis, 2010)Trondheim havn er en stor transporthavn hvor det er påvist sterkt forurensede bunnsedimenter i store deler av havneområdet. Sammen med Trondheimsfjorden Interkommunale Havn (TIH), har Trondheim kommune satt i gang prosjektet ... -
Multi-Factor Interest Rate Models and Portfolio Management within Life Insurance Companies in Low-Rate Environments
(Master thesis, 2016)In this Master's thesis we study the equity market and the two multi-factor interest rate models Heath-Jarrow-Morton model (HJM) and the LIBOR market model (LMM) on the Norwegian, European and US interest rate market. These ... -
Multi-fidelity information fusion with concatenated neural networks
(Journal article; Peer reviewed, 2022)Recently, computational modeling has shifted towards the use of statistical inference, deep learning, and other data-driven modeling frameworks. Although this shift in modeling holds promise in many applications like design ... -
Multi-instance Secure Public-Key Encryption

Multi-user security for Schnorr-like signature schemes
(Bachelor thesis, 2022)I denne oppgaven skal jeg først ta for meg et sikkerhetsbevis for Schnorr-signaturalgoritmen. Beviset inneholder flere steg der vi begynner med Schnorrs identifikasjonsprotokoll som er basert på vanskeligheten ved å løse ... -
Multicomplexes and their spectral sequences
(Master thesis, 2022)Multikomplekser generaliserer kjedekomplekser og dobbeltkomplekser. Vi ser hovedsaklig på spektralfølgen tilhørende et multikompleks over en kropp og gir betingelser for degenerasjon på første side i spektralfølgen. Videre ... -
Multicriteria optimization problems
(Bachelor thesis, 2021)In this bachelor thesis, we will consider various themes in multiobjective optimization. In particular, we will look at some optimality notions, existence results, scalarization results, and some problems in uncertain ... -
Multifactor Interest Rate Models in Low-Rate Environments
(Master thesis, 2013)This thesis studies a multi-factor Heath-Jarrow-Morton model and a LIBOR mar- ket model on the Norwegian, European and US interest rate market. The main concerns are the low-rate environment and exposure to negative interest ... -
Multigrid preconditioning of the linear elasticity equation
(Master thesis, 2016)Multigrid methods are known to be very efficient linear solvers for 2nd order elliptic PDEs. In this thesis we consider multigrid methods, and the use of such as preconditioners, when solving the linear elasticity equation. ... -
Multilevel Analysis Applied to Fetal Growth Data with Missing Values.
(Master thesis, 2006)Intrauterine growth retardation means that the growth of a fetus is restricted as compared with its biological growth potential. This contributes to an increased risk for illnesses or death of the newborn. Therefore it ... -

A multimesh finite element method for the Navier–Stokes equations based on projection methods
(Peer reviewed; Journal article, 2020)The multimesh finite element method is a technique for solving partial differential equations on multiple non-matching meshes by enforcing interface conditions using Nitsche’s method. Since the non-matching meshes can ... -
Multiple Proposal Strategies for Markov Chain Monte Carlo
(Master thesis, 2006)The multiple proposal methods represent a recent simulation technique for Markov Chain Monte Carlo that allows several proposals to be considered at each step of transition. Motivated by the ideas of Quasi Monte Carlo ... -
Multiplicative and semi-multiplicative functions on non-crossing partitions, and relations to cumulants
(Peer reviewed; Journal article, 2023)We consider the group (Ǧ, ∗)of unitized multiplicative functions in the incidence algebra of non-crossing partitions, where “∗” denotes the convolution operation. We introduce a larger group (Ǧ, ∗) of unitized functions ... -
Multiscale Finite Volume Methods: Extension to Unstructured Grids with Applications in Reservoir Simulation
(Master thesis, 2012)In reservoir simulations, one of the biggest challenges is solving large modelswith complex geological properties. Because reservoirs can be several kilome-ters long, and still be geologically inhomogeneous over centimeters, ... -
Multiscale Methods and Flow-based Gridding for Flow and Transport In Porous Media
(Doktoravhandlinger ved NTNU, 1503-8181; 2010:181, Doctoral thesis, 2010)The topic of this thesis is fast and accurate simulation techniques used for simulations of flow and transport in porous media, in particular petroleum reservoirs. Fast and accurate simulation techniques are becoming ... -
Multiscale Modelling of Elastic Parameters
(Master thesis, 2008)Petrophysical properties in general and elasticity in particular have heterogeneous variations over many length scales. In a reservoir model, on which one for example can simulate fluid flow, seismic responses and resisitivity, ... -
Multiscale Simulation of Thermal Flow in Porous Media
(Master thesis, 2016)In this thesis we develop a multiscale method that solves non-isothermal flow in porous media. A sequential formulation is established that decouples corresponding equations into three systems, one pertaining pressure, one ... -
Multistate models in survival analysis using INLA, applied on data for resuscitation after cardiac arrest
(Master thesis, 2022)Levetidsanalyse er studiet av data som beskriver tiden til en bestemt hendelse. Inkludering av flere hendelser er ofte nødvendig for å lage en mer nøyaktig modell av verden, og disse modellene blir referert til som ...
