Cumulants in Non-commutative:Probability via Hopf Algebras
(Doctoral theses at NTNU;2022:370, Doctoral thesis, 2022)The notion of cumulants plays a significant role in the combinatorial study of noncommutative probability theory. In this thesis, we study several problems associated with the notions of cumulants for free, Boolean and ... -

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

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 ... -

Efficient Solvers for Field-Scale Simulation of Flow and Transport in Porous Media
(Doctoral theses at NTNU;2019:374, Doctoral thesis, 2019)The first part of the thesis serves as an introduction to modelling of flow and transport in porous media from the perspective of reservoir simulation. We discuss generation of computational grids and discretization ... -
Elevenes motivasjon for å lære matematikk og undersøkende matematikkundervisning
(Doktoravhandlinger ved NTNU, 1503-8181; 2007:262, Doctoral thesis, 2007)Avhandlingen fokuserer på elevenes motivasjon for å lære matematikk. Studiens overordnede forskningsspørsmål er: Hvordan kan elevers motivasjon for å lære matematikk utvikle seg når de opplever en matematikkundervisning ... -

Ensemble-based data assimilation methods applied to geological process modeling
(Doctoral theses at NTNU, 2018:404, Doctoral thesis, 2018)Summary: Data assimilation is the art of conditioning a numerical simulation of a physical process on observations of the real process. That is, adjusting estimates so that they agree not only with a mathematical model ... -

Fault controlled pressure modelling in sedimentary basins /
(Dr. ingeniøravhandling, 0809-103X; 2000:22, Doctoral thesis, 2000)The starting point for this Dr. Ing. thesis was the requirement for models describing basin scale overpressure for use in basin modelling studies. It is necessary to identify, understand and describe both the generating ...
