Matrix factorizations for self-orthogonal categories of modules
(Peer reviewed; Journal article, 2020)For a commutative ring S and self-orthogonal subcategory C of Mod(S), we consider matrix factorizations whose modules belong to C. Let f∈S be a regular element. If f is M-regular for every M∈C, we show there is a natural ... -
Matui’s AH Conjecture for Graph Groupoids
(Peer reviewed; Journal article, 2021)We prove that Matui’s AH conjecture holds for graph groupoids of infinite graphs. This is a conjecture which relates the topological full group of an ample groupoid with the homology of the groupoid. Our main result ... -
Maximal norm Hankel operators

Maximal τ_d-rigid pairs
(Journal article; Peer reviewed, 2020)Let C be a 2-Calabi–Yau triangulated category, T a cluster tilting object with endomorphism algebra Γ. Consider the functor C(T,-): C -> mod Γ. It induces a bijection from the isomorphism classes of cluster tilting objects ... -
Maximum Principles for Differential Equations
(Master thesis, 2014)maximum principle is one among the most useful and best known tools used in the study of partial differential equations. This principle is a generalization of the well known fact of calculus that any function u(x) which ... -
Maximum Principles in Differential Equations
(Master thesis, 2012)The aim of this thesis is to investigate the maximum principle, which is one of the most important tools employed in differential equations. Specifically, we explore the maximum principle for linear second-order elliptic ... -
Mean field limit for one dimensional opinion dynamics with Coulomb interaction and time dependent weights
(Journal article; Peer reviewed, 2024)The mean field limit with time dependent weights for a 1D singular case, given by the attractive Coulomb interactions, is considered. This extends recent results (Ayi and Duteil, 2021; Duteil, 2022) for the case of regular ... -
Measurement of the dispersion relation for random surface gravity waves
(Journal article; Peer reviewed, 2015)We report laboratory experiments and numerical simulations of the Zakharov equation, designed to have sufficient resolution in space and time to measure the dispersion relation for random surface gravity waves. The experiments ... -
Measuring Summary Quality using Weak Supervision
(Master thesis, 2021)I dette arbeidet analyserer vi tilstandsrapportar for bustad, og deira samandrag. Studiar har antyda at mange kjøparar av bustad ikkje tek seg tid til å lese heile tilstandsrapportar, og berre les samandrag i staden. Dette ... -
Mesh Generation Techniques for Isogeometric Analysis
(Master thesis, 2015)In any method aimed at solving a boundary value problem using isogeometric analysis, it is imperative to find a high quality parameterization of the domain over which the partial differential equation is posed. The ... -
meta4diag: Bayesian bivariate meta-analysis of diagnostic test studies for routine practice
(Journal article; Peer reviewed, 2017)This paper introduces the R package meta4diag for implementing Bayesian bivariate meta-analyses of diagnostic test studies. Our package meta4diag is a purpose-built front end of the R package INLA. While INLA offers full ... -
Metakognisjon og generalisering: En studie om utfordringer og metakognitiv påvirkning i generaliseringsprosessen
(Master thesis, 2010)Målet med studien var å utvide perspektivet på elevers læring i algebra. Studien ble basert på følgende problemstilling: Hvordan virker elever sin metakognisjon inn på løsning av generaliserings¬oppgaver? Gjennom en ... -
Metaplectic transformations and finite group actions on noncommutative tori
(Journal article; Peer reviewed, 2019)In this article we describe extensions of some K-theory classes of Heisenberg modules over higher-dimensional noncommutative tori to projective modules over crossed products of non\-commutative tori by finite cyclic groups, ... -
Metaplectic Transformations for Gabor Frames and Equivalence Bimodules
(Master thesis, 2023)Målet med denne avhandlingen er å presentere og utforske en symplektisk tilnærming til gaboranalyse – gaboranalyse er et emne innen tid-frekvens-analyse som er nært knyttet både til informasjon- og kommunikasjonsteknologier ... -
Meteorological observations in tall masts for the mapping of atmospheric flow in Norwegian fjords
(Peer reviewed; Journal article, 2020)Since 2014, 11 tall meteorological masts have been erected in coastal areas of mid-Norway in order to provide observational data for a detailed description of the wind conditions at several potential fjord crossing sites. ... -
Methods for Analysis of Big Data.: A Combination of the Lasso Method and the Case-Crossover Design for Investigating Potential Drug Side Effects on Myocardial Infarction
(Master thesis, 2014)The current master thesis was written during the academic year 2013 − 2014 atthe Norwegian University of Science and Technology (NTNU). It concerns the im-plementation of the case-crossover design in a combination with the ... -
Methods for Analyzing the 12 Run Plackett-Burman Design
(Master thesis, 2014)In the early stages of an experimental analysis it is often of interest to determine the most important factors. The main goal of this master thesis is to study and compare different methods for determining the active ... -
Methods for Dealing with Censored Data using Experimental Design
(Master thesis, 2013)In reliability theory, it is common that data are missing due to censoring. This results in an incomplete data set which is often difficult to analyze. Methods are tested in search of the missing values, creating a fictional ... -
Methods for Extreme Value Statistics Based on Measured Time Series
(Master thesis, 2008)The thesis describes the Average Exceedance Rate (AER) method, which is a method for predicting return levels from sampled time series. The AER method is an alternative to the Peaks over threshold (POT) method, which is ... -
