FINITE ElEMENT METHODS APPLIED TO GROUNDWATER MODEL PROBLEMS, IMPLEMENTED WITH THE USE OF FEniCs
(Master thesis, 2011)In this thesis an attempt is made to discuss the finite element meth-ods and FEniCs. Its main objective is to provide a general overview offinite element method specially, variational formulation of partial differen-tial ... -
Finite element solutions to the wave equation in non-convex domains - A relaxation of the CFL condition in the presence of local mesh refinement
(Master thesis, 2017)Finite element solutions in non-convex domains generally suffer from reduced convergence rates due to reduced regularity. This is also the case for the wave equation. To remedy the situation, (strong) local mesh refinement ... -
Finite type cluster-tilted algebras and cluster structures in 2-CY categories
(Doktoravhandlinger ved NTNU, 1503-8181; 2009:145, Doctoral thesis, 2009) -
Finite-rank Bratteli-Vershik diagrams are expansive—a new proof
(Journal article; Peer reviewed, 2017)Downarowicz and Maass (Ergod. Th. and Dynam. Sys. 28 (2008), 739–747) proved that the Cantor minimal system associated to a properly ordered Bratteli diagram of finite rank is either an odometer system or an expansive ... -
Finite-Volume High-Fidelity Simulation Combined with Finite-Element-Based Reduced-Order Modeling of Incompressible Flow Problems
(Journal article; Peer reviewed, 2019)We present a nonintrusive approach for combining high-fidelity simulations using Finite-Volume (FV) methods with Proper Orthogonal Decomposition (POD) and Galerkin Reduced-Order Modeling (ROM) methodology. By nonintrusive ... -
Finiteness Obstruction in Model Categories
(Master thesis, 2021)Vi viser in denne oppgaven at det er en naturlig måte og gjøre god for endelighets obstruksjon i en generell modell kategori. Operatoren $(Wa(-), w(-))$ vises å være en funktor fra modell kategorier hvor det eksisterer ... -
Finitistic Dimension Conjecture
(Master thesis, 2021)I denne oppgaven oppsummerer vi arbeidet gjort på finitistisk dimensjonsformodning for endeligdimensjonale algebraer siden den først ble postulert i 1960. Vi fokuserer spesielt på å vise hvilke klasser av algebraer hvor ... -
A FIRST BIBLIOGRAPHY ON SET AND VECTOR OPTIMIZATION PROBLEMS WITH RESPECT TO VARIABLE DOMINATION STRUCTURES
(Journal article; Peer reviewed, 2022)This bibliography lists 107 papers dealing with variable domination structures in vector and set optimization, and its applications and numerics. A classification is given in terms of different sub-branches where variable ... -
First- and Second-Order Analysis for Optimization Problems with Manifold-Valued Constraints
(Peer reviewed; Journal article, 2022)We consider optimization problems with manifold-valued constraints. These generalize classical equality and inequality constraints to a setting in which both the domain and the codomain of the constraint mapping are smooth ... -
Flat Bundles Over Some Compact Complex Manifolds
(Journal article; Peer reviewed, 2019)We construct examples of flat fiber bundles over the Hopf surface such that the total spaces have no pseudoconvex neighborhood basis, admit a complete Kähler metric, or are hyperconvex but have no nonconstant holomorphic ... -
Flerspråklige elever i møte med tekstoppgaver i matematikk - En casestudie av 18 voksne innvandrerelever som belyser hvilke utfordringer de opplever i arbeidet med tekstoppgaver i matematikk
(Master thesis, 2017)Målet med denne oppgaven er å belyse hvilke aspekter ved tekstoppgaver i matematikk oppleves som vanskelige for flerspråklige elever. Motivasjonen bak temavalget er et ønske om å kunne konkretisere hvilke tiltak som kan ... -
Flexible modelling of spatial variation in agricultural field trials with the R package INLA
(Journal article; Peer reviewed, 2019)The objective of this paper was to fit different established spatial models for analysing agricultural field trials using the open-source R package INLA. Spatial variation is common in field trials, and accounting for it ... -
Flow equivalence and orbit equivalence for shifts of finite type and isomorphism of their groupoids
(Journal article; Peer reviewed, 2018)We give conditions for when continuous orbit equivalence of one-sided shift spaces implies flow equivalence of the associated two-sided shift spaces. Using groupoid techniques, we prove that this is always the case for ... -
Flow-times in an M/G/1 Queue under a Combined Preemptive/Non-preemptive Priority Discipline.: Scheduled Waiting Time on Single Track Railway Lines
(Master thesis, 2010)A priority based rule for use during the process of scheduling trains oper- ating on a single track railway line was proposed by the Norwegian railway operator and owner, Jernbaneverket. The purpose of this study is to ... -
Follow-the-leader models can be viewed as a numerical approximation to the Lighthill-Whitham-Richards model for traffic flow
(Journal article; Peer reviewed, 2018) -
A footnote to a theorem Halász
(Journal article; Peer reviewed, 2020)We study multiplicative functions f satisfying |f(n)|≤1 for all n, the associated Dirichlet series F(s):=∑∞n=1f(n)n−s, and the summatory function Sf(x):=∑n≤xf(n). Up to a possible trivial contribution from the numbers ... -
Forecast Uncertainty for Univariate Time Series Using Generative Adversarial Networks
(Master thesis, 2020)Når man skal predikere fremtidige verdier av en tidsrekke er usikkerheten i prediksjonene en viktig faktor. Nylig har konkurranser innen tidsrekke-prediksjon vist at nevrale nettverk presterer svært godt, men usikkerhetsmålet ... -
Forecasting Child Mortality while Accounting for Complex Survey Design
(Master thesis, 2019)Barnedødelighetsrater er viktige indikatorer på en nasjons helse. FNs tusenårsmål (MDG) og bærekraftsmål (SDG) fokuserer på å redusere barnedødelighet. Man trenger nøyaktige estimater og prediksjoner for nyfødtdødelighet ... -
Forecasting Day-Ahead Electricity Spot Prices, With Applications to the German Electricity Market
(Master thesis, 2019)Denne masteroppgaven har studert det tyske elektrisitetsmarkedet, i den hensikt å predikere neste dags elektrisitetsspotpriser. Tre modeller er presentert; den første modellen er en "persistence"-modell, som fungerer som ... -
Forecasting Red Wine Rankings at Vinmonopolet with Machine Learning
(Master thesis, 2021)I Norge blir salg av drikkevarer med over 4,75 % alkohol monopolisert av Vinmonopolet og kontrollert av strenge lover som forbyr reklame. Vinmonopolet bytter produktutvalg annenhver måned, der de lanserer nye produkter og ...
