Deep Learning with emphasis on extracting information from text data
(Master thesis, 2016)In this thesis the Natural Language Processing (NLP) problems of predicting the negative or positive sentiment of a movie review (sentiment analysis) and Automated Essay Grading (AES) were analyzed. The data set used for ... -
Deep neural network enabled corrective source term approach to hybrid analysis and modeling
(Peer reviewed; Journal article, 2022)In this work, we introduce, justify and demonstrate the Corrective Source Term Approach (CoSTA)—a novel approach to Hybrid Analysis and Modeling (HAM). The objective of HAM is to combine physics-based modeling (PBM) and ... -
Deep neural networks on diffeomorphism groups for optimal shape reparametrization
(Journal article; Peer reviewed, 2023)One of the fundamental problems in shape analysis is to align curves or surfaces before computing geodesic distances between their shapes. Finding the optimal reparametrization realizing this alignment is a computationally ... -
Defining and applying a new approximation for the parametric probability densities of spherical particle profile sizes
(Peer reviewed; Journal article, 2022)A novel approximation for the parametric probability densities of spherical particle profile diameters is suggested. The spheres are approximated from solids obtained by rotating regular polygons around their axes of ... -
Definitions for Plaintext-Existence Hiding in Cloud Storage
(ARES 2018;Article No. 41, Chapter, 2018)Cloud storage services use deduplication for saving bandwidth and storage. An adversary can exploit side-channel information in several attack scenarios when deduplication takes place at the client side, leaking information ... -
Deformations and Balian-Low theorems for Gabor frames on the adeles

Degeneration and related partial orders in representation theory.
(Doctoral thesis at NTNU;2015:265, Doctoral thesis, 2015) -
Degeneration as a Partial Order on Module Categories
(Master thesis, 2007)Chapter 1 contains most of the background material for this thesis. In Chapter 2 we provide a formal method for determining degeneration for algebras of finite representation type. In Chapter 3 we give an alternative ... -
Degeneration of Representations of Algebras and Quivers
(Master thesis, 2022)Representasjonar av assosiative algebraar er homomorfiar frå algebraen inn i ein matrisealgebra. Ein gruppeverknad kan definerast på mengda av representasjonar som korresponderar med konjugering av matriser. Banene under ... -
Degenerations and other partial orders on the space of representations of algebras
(Master thesis, 2013)Let K be a field and¤be an artin K-algebra. Let r epd¤represent the set of all¤-modules with the length equal to a natural number d as a K-vector space. The set of modules r epd¤ is equipped with the action of the general ... -
Degenerering i modulvarieteter
(Master thesis, 2021)La M og N vera to matriser, og la den generelle lineære gruppa av invertible matriser verke på desse ved konjugering. Då seier me at M degenererer til N dersom N ligg i tillukkinga av banen til gruppeverknaden på M. Dersom ... -
Delousing Effect and Welfare Implications of Non-Medicinal Delousing Methods
(Master thesis, 2023)Lakselusen (Lepeophtheirus salmonis) er en parasitt som påvirker velferden til atlanterhavslaksen. De siste årene har det vært økende interesse for å bruke ikke-medikamentelle metoder for å bekjempe lus, men disse behandlingene ... -
Demographic routes to variability and regulation in bird populations
(Journal article; Peer reviewed, 2016)There is large interspecific variation in the magnitude of population fluctuations, even among closely related species. The factors generating this variation are not well understood, primarily because of the challenges ... -
Demonstrating the impact of bidirectional coupling on the performance of an ocean-met model
(Journal article; Peer reviewed, 2017)The mass, momentum and energy fluxes between the atmosphere and ocean surface depend on the state of the ocean surface. The fluxes in turn can significantly alter the nature of the marine boundary layer and the state of ... -
Den Cramér-stokastiske modellen for primtala
(Bachelor thesis, 2020)Målet med denne oppgåva er å introdusera Cramér-modellen, og å drøfta om den modellerer primtala på ein rimeleg måte. Motivasjonen bak modellen vert forklart og modellen vert definert. Somme av krava modellar av primtala ... -
Depth consistent pp and ps seismic angle tomography
(Doktoravhandlinger ved NTNU, 1503-8181; 2004:18, Doctoral thesis, 2004)This thesis addressed the problem of finding background models yielding depth consistent migrated PP and PS images, i.e. geologically equivalent reflectors should be imaged at the same depth in the two images. The tomographic ... -
Derived categories of gentle and skewed-gentle algebras: A combinatorial approach
(Doctoral thesis at NTNU;2015:278, Doctoral thesis, 2015) -
Derived equivalence classification techniques for Nakayama algebras
(Doctoral theses at NTNU;2024:18, Doctoral thesis, 2024)In the representation theory of finite dimensional algebras, the fundamental goal is to understand the structure of the category mod⇤ of finite dimensional modules over an algebra ⇤. While solving this problem is difficult ... -
Design Optimization of Propeller Duct
(Master thesis, 2009)This Master Thesis ends up in a design optimization of a propeller duct profile as an example of multi-objective optimization with computationally expensive objective function evaluation. Computational Fluid Dynamics ... -
Design- and Model-Based Approaches to Small-Area Estimation in a Low and Middle Income Country Context: Comparisons and Recommendations
(Peer reviewed; Journal article, 2020)The need for rigorous and timely health and demographic summaries has provided the impetus for an explosion in geographic studies in low- and middle-income countries. Many of these studies present fine-scale pixel-level ...
