Stochastic Automatic Gradient Tree Boosting
(Master thesis, 2021-11-22) -
Stochastic chain-ladder models in nonlife insurance
(Master thesis, 2008)This thesis examines the stochastic models which reproduce chain-ladder estimates used in reserve estimation for nonlife insurance. The chain-ladder method provides no information regarding the variability of the outcome, ... -
Stochastic data assimilation of observations with a detection limit
(Doctoral thesis, 2019-09-16) -
Stochastic organelle genome segregation through Arabidopsis development and reproduction
(Journal article; Peer reviewed, 2024)Organelle DNA (oDNA) in mitochondria and plastids is vital for plant (and eukaryotic) life. Selection against damaged oDNA is mediated in part by segregation – sorting different oDNA types into different cells in the ... -
Stochastic unit-root processes
(Master thesis, 2016-06-01)In practice there are many types of processes that have near unit roots and are very difficult to distinguish from standard unit-root processes, given a finite sample. In our thesis we study a particular class of such ... -
Stokes drift and particle trajectories induced by surface waves atop a shear flow
(Journal article; Peer reviewed, 2024)Surface waves and currents are crucial to the mass transfer in the air-sea interaction as they can drive a variety of dynamical processes. How mass can be transported by surface waves and current coupling is addressed ... -
Streamline based History Matching
(Master thesis, 2009-05-07)Streamline based reservoir simulation has been used with great success in the petroleum industry for decades. Fast computational speed together with the fact that sensitivities can be computed analytically along streamlines ... -
A Streamline Front Tracking Method for Two- and Three-Phase Flow Including Capillary Forces
(Contemporary Mathematics; 295, Chapter, 2002) -
A streamline front tracking method for two- and three-phase flow including capillary forces.
(Department of Applied Mathematics report, Research report, 2001-10) -
Streamline methods for parabolic differential equations.
(Master thesis, 2008)Parabolic advection-diffusion equations arise when modelling flow in porous media. We will in this thesis discuss two different problem set-ups from which these types of equations arise. - Groundwater contamination with ... -
Streamline Tracing on Irregular Grids
(Master thesis, 2003) -
Stromule Geometry Allows Optimal Spatial Regulation of Organelle Interactions in the Quasi-2D Cytoplasm
(Journal article; Peer reviewed, 2023)In plant cells, plastids form elongated extensions called stromules, the regulation and purposes of which remain unclear. Here, we quantitatively explore how different stromule structures serve to enhance the ability of a ... -
A strongly degenerate convectio-diffusion Problem modeling centrifugation of flocculated Suspensions.

Strongly interacting solitary waves for the fractional modified Korteweg-de Vries equation
(Journal article; Peer reviewed, 2023)We study one particular asymptotic behaviour of a solution of the fractional modified Korteweg-de Vries equation (also known as the dispersion generalised modified Benjamin-Ono equation): ∂tu + ∂x(−|D|αu + u3) = 0. The ... -
Students’ evaluation of academic courses: An exploratory analysis to an Italian case study
(Journal article; Peer reviewed, 2021)Students’ evaluations of teaching is a common practice in higher education institutions, with the main purpose of improving course quality and effectiveness. In this paper we would like to contribute to the existing ... -
A study in the effects of different treatments on the growth of high fluorescence virus.
(Master thesis, 2011-09-01) -
A study in Univalence
(Master thesis, 2014-06-02)In this master thesis we want to study the newly discovered homotopy type theory, and its models within mathematics. We look at models in simplicial sets, simplicial symmetric monoids, and a new category which could be ... -
A study of different interactions between solitary waves for fractional Korteweg-de Vries type equations
(Doctoral thesis, 2023-01-13)Denne avhandlingen er satt sammen av tre artikler. I den første konstruerer vi $N$-soliton løsninger for den fractional Korteweg-de Vries (fKdV) ligningen $\partial_t u - \partial_x\left(|D|^{\alpha}u - u^2 \right)=0,$ i ... -
A study of the diffusive properties of a modified compressible Navier-Stokes model
(Journal article; Peer reviewed, 2022)The aim of this study is to provide further validation for the weakly well-posed modified compressible Navier-Stokes system proposed in Svärd (Phys A 506:350–375, 2018) when applied to ideal gases. We do so by considering ... -
A study of the influence of vorticity, capillarity and slope angle on the properties of shoaling and breaking waves
(Doctoral thesis, 2021-10-28)Fluid motion and wave patterns have fascinated humans for centuries if not millennia. Water waves have been studied out of curiosity such as observing the ripples created by a stone dropped in a pond as well as practical ...
