Object tracking and classification using distributed acoustic sensing
(Master thesis, 2024)Multi-objekt målfølging (MOT) omfatter et matematisk rammeverk laget for å estimere kinematiske egenskaper av objekter som beveger seg i henhold til en dynamisk modell i et begrenset overvåket romlig område. Bayesiansk ... -
Objective Beliefs and Bayes Estimators: An Approach to Parameter Estimation Using Objective Priors and Distance Between Distributions
(Master thesis, 2020)Denne oppgaven tar for seg problemet med å estimere parametre i statistisk analyse, og i særdeleshet Bayesiansk analyse. Gitt en modell utledes objektive a priori-fordelinger for parametrene. De resulterende fordelingene ... -
Objective inference for correlation
(Master thesis, 2021)Denne masteroppgaven tar for seg problemstillingen om å hente mest mulig informasjon om korrelasjonen i en binormal fordeling basert på observerte punkter i planet. Forventningsverdiene og variansene er antatt kjente. Til ... -
Obstructions to the Surjectivity of the Thom Homomorphism
(Master thesis, 2020)Vi presenterer de grunnlegende egenskapene til stabil homotopiteori og generalisert kohomologi og konstruerer Thom-homomorfien fra kompleks kobordisme til singulær kohomologi. Deretter studerer vi denne homomorfien mer ... -
Obtaining Numerical Solutions to Ordinary Differential Equations on Differentiable Manifolds with Lie Group Integrators
(Master thesis, 2021)Ordinære differensiallikningar (ODE-ar) er sentralt i fleire fagfelt; til dels mekanikk, finans, og det å lage vêrmeldingar. Dei velkjende Runge-Kutta metodane er ein av dei vanlegaste måtane å finne numeriske løysingar ... -
Offline Assisted Group Key Exchange
(Journal article; Peer reviewed, 2018)We design a group key exchange protocol with forward secrecy where most of the participants remain offline until they wish to compute the key. This is well suited to a cloud storage environment where users are often offline, ... -
Ola Bratteli and His Diagrams
(Peer reviewed; Journal article, 2020) -
Om Banachs fikspunktteorem og The Scottish Café: -Anvendelser av Banachs fikspunktteorem. -Kulturhistorisk bakgrunn for forståelsen av The Scottish Café.
(Master thesis, 2006)Sammendrag I kapittel 1 gjøres klart hvilke forkunnskaper som er nødvendige for å kunne forstå og ha utbytte av å lese denne oppgaven. Det henvises også til litteratur som kan brukes som oppslagsverk hvis noen begreper ... -
Om Buen: Form, Optimering og Dynamikk
(Master thesis, 2012)Denne masteroppgaven i analyse undersøker noen interesante matematiske problemer tilknyttet buemaking og bueskyting. Dette inkluderer temaer som form og optimering av en bue. Vi vil beskrive en bues form og hvordan denne ... -
On (co)ends in ∞-categories
(Peer reviewed; Journal article, 2022)In this short note we prove that two definitions of (co)ends in ∞-categories, via twisted arrow ∞-categories and via ∞-categories of simplices, are equivalent. We also show that weighted (co)limits, which can be defined ... -
On a (No Longer) New Segal Algebra: A Review of the Feichtinger Algebra
(Journal article; Peer reviewed, 2018)Since its invention in 1979 the Feichtinger algebra has become a useful Banach space of functions with applications in time-frequency analysis, the theory of pseudo-differential operators and several other topics. It is ... -
On a Low-Rank Matrix Single-Index Model
(Journal article; Peer reviewed, 2023) -
On a shallow water wave equation
(Doktoravhandlinger ved NTNU, 1503-8181; 2006:103, Doctoral thesis, 2006)The main topic of this thesis is the study of a nonlinear partial differential equation, the Camassa-Holm (CH) equation: ut - utxx + 3uux - 2uxuxx -uuxxx = 0. -
On a Traffic Flow Model
(Doktoravhandlinger ved NTNU, 1503-8181; 2008:256, Doctoral thesis, 2008) -
On Accumulated Cohen's Class Distributions and Mixed-State Localization Operators
(Journal article; Peer reviewed, 2019)Recently we introduced mixed-state localization operators associated with a density operator and a (compact) domain in phase space. We continue the investigations of their eigenvalues and eigenvectors. Our main focus is ... -
On angular measures in axiomatic Euclidean planar geometry
(Peer reviewed; Journal article, 2022)We address the issue of angular measure, which is a contested issue for the International System of Units (SI).We provide a mathematically rigorous and axiomatic presentation of angular measure that leads to the traditional ... -
On approximations of the forward-backward algorithm for a switching linear Gaussian model.
(Master thesis, 2009)In this report, the forward-backward algorithm is derived and explained for a one-layer and a two-layer Hidden Markov model. We describe the structure of the hidden Markov models, before we enter the world of the ... -
On cluster-tilting modules for some symmetric algebras
(Master thesis, 2020)Klassifisering av kluster-vipping-modular til nokre symmetriske algebraar -
On complex dynamics in a Purkinje and a ventricular cardiac cell model
(Journal article; Peer reviewed, 2021)Cardiac muscle cells can exhibit complex patterns including irregular behaviour such as chaos or (chaotic) early afterdepolarisations (EADs), which can lead to sudden cardiac death. Suitable mathematical models and their ... -
On conjectures of Hovey–Strickland and Chai
(Peer reviewed; Journal article, 2022)We prove the height two case of a conjecture of Hovey and Strickland that provides a K(n)-local analogue of the Hopkins–Smith thick subcategory theorem. Our approach first reduces the general conjecture to a problem in ...
