Genetic Group Animal Models in the Genomics Era
(Master thesis, 2021)Denne masteroppgaven tar for seg bruk av dyremodeller med genetiske grupper i studier der vi ser på villdyr-populasjoner. Dyremodellen er en generalisert lineær blandet modell som lar oss undersøke genetiske parametere i ... -
Genomic estimation of quantitative genetic parameters in wild admixed populations
(Peer reviewed; Journal article, 2022)1. Heritable genetic variation among free-living animals or plants is essential for populations to respond to selection and adapt. It is therefore important to be able to estimate additive genetic variance VA, which can ... -
Genomic prediction including SNP-specific variance predictors
(Journal article; Peer reviewed, 2019)The increasing amount of available biological information on the markers can be used to inform the models applied for genomic selection to improve predictions. The objective of this study was to propose a general model for ... -
Gentle Algebras and a Geometric Model for the Module Category
(Master thesis, 2021)I denne oppgaven viser vi at milde algebraer er isomorfe til flisalgebraer. Flisalgebraer kan visulaiseres som en lamineringsalgebra, som brukes til å gjenopprette den milde algebraen. Disse isomorfiene danner grunnlaget ... -
Genuine-commutative structure on rational equivariant K-theory for finite abelian groups
(Peer reviewed; Journal article, 2022)In this paper, the authors build on their previous work to show that periodic rational -equivariant topological -theory has a unique genuine-commutative ring structure for a finite abelian group. This means that every ... -
Geodesics on Surfaces
(Master thesis, 2016)We study geodesics on surfaces in the setting of classical differential geometry. We define the curvature of curves and surfaces in three-space and use the fundamental forms of a surface to measure lengths, angles, and ... -
Geometric and Functional Analytic Aspects of Time-Frequency Analysis
(Doctoral theses at NTNU;2022:74, Doctoral thesis, 2022)Sammendrag på norsk Denne avhandlingen omhandler geometriske og funksjonalanalytiske aspekter ved tid-frekvensanalyse. Mer spesifikt drøfter avhandlingen de tre følgende delvis relaterte temaene: Dekomponeringsrom: I ... -
Geometric and integrability properties of Kahan?s method: The preservation of certain quadratic integrals
(Peer reviewed; Journal article, 2019)Given a quadratic vector field on possessing a quadratic first integral depending on two of the independent variables, we give a constructive proof that Kahan's discretization method exactly preserves a nearby modified ... -
Geometric Hodge filtered complex cobordism
(Doctoral theses at NTNU;2022:238, Doctoral thesis, 2022)We define geometric Hodge filtered complex cobordism groups MUn(p)(X) for complex manifolds X. Refining the Pontryagin–Thom construction, we give a natural isomorphism MUn(p)(X) ƒ MUnD (p)(X), where MUnD(p)(X) are the Hodge ... -
Geometric Hodge filtered complex cobordism
(Peer reviewed; Journal article, 2023)We construct a geometric cycle model for a Hodge filtered extension of complex cobordism for every smooth manifold with a filtration on its de Rham complex with complex coefficients. Using a refinement of the Pontryagin–Thom ... -
Geometric integration of nonlinear wave equations
(Master thesis, 2007)We give an short introduction to the Camassa-Holm equation and its travelling wave solutions. Many well-known equations in mathematical physics describe geodesic flows on appropriate Lie groups. The choice of group and ... -
Geometric Integration of ODEs Using Multiple Quadratic Auxiliary Variables

Geometric pushforward in Hodge filtered complex cobordism and secondary invariants
(Journal article; Peer reviewed, 2024)We construct a functorial pushforward homomorphism in geometric Hodge filtered complex cobordism along proper holomorphic maps between arbitrary complex manifolds. This significantly improves previous results on such ... -
Geometric reduction and the three body problem
(Doktoravhandlinger ved NTNU, 1503-8181; 2012:211, Doctoral thesis, 2012)This dissertation investigates a particular reduction of the three body problem, using a combination of Riemannian geometry and geometric invariant theory of three body motions in Euclidean space. Our point of departure ... -

Geometry-Based Modeling of Wideband Industrial Indoor Radio Propagation Channels
(Chapter, 2015)In this paper, we present a geometrical scattering model for a typical class of industrial indoor environments. The proposed industrial reference model takes into account scattering components arising from metallic structures ... -
Geostatistical Analysis of DHS Data: Accounting for Random Displacement of Survey Locations

Geostatistical Modeling under Positional Uncertainty
(Master thesis, 2023)I denne oppgaven undersøker vi posisjonell usikkerhet i geostatistisk modellering. Et sentralt eksempel på posisjonell usikkerhet er bruken av geografisk maskering (geomaskering) ment til å beskytte personvern. Geomaskering ... -
A geostatistical spatially varying coefficient model for mean annual runoff that incorporates process-based simulations and short records
(Peer reviewed; Journal article, 2022)We present a Bayesian geostatistical model for mean annual runoff that incorporates simulations from a process-based hydrological model. The simulations are treated as a covariate and the regression coefficient is modeled ... -
Global Bifurcation of a Nonlocal Equation
(Master thesis, 2022)Vi studerer en dispersiv likning av typen fraksjonell Korteweg–de Vrie [38, 46] med en ikke-lokal ikkelineæritet som er en Coifman–Meyer operator [14], som når betraktet i stabile variabler antar formen -µϕ + Λ^s ϕ + ϕ Λ^r ...
