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 ... -
A Study of the Modelling Error in two Operator Splitting Algorithms for porous Media Flow
(Department of Applied Mathematics report, Research report, 1997-10) -
A Study of the Verigin Problem with Application to Analysis of Water Injection Tests
(Department of Applied Mathematics report, Research report, 1985-03) -
A Study on Continuous Max-Flow and Min-Cut Approaches
(Chapter; Peer reviewed, 2010)We propose and investigate novel max-flow models in the spatially continuous setting, with or without supervised constraints, under a comparative study of graph based max-flow / min-cut. We show that the continuous max-flow ... -
A study on iterative methods for Richards' equation
(Peer reviewed; Journal article, 2016-04)This work concerns linearization methods for efficiently solving the Richards equation, a degenerate elliptic-parabolic equation which models flow in saturated/unsaturated porous media. The discretization of Richards’ ... -
Sub-bases of pleasant h-bases
(Department of Pure Mathematics report no. 14, Research report, 1987-02) -
Sub-Riemannian geometry of spheres and rolling of manifolds
(Doctoral thesis, 2011-04-29) -
Sub-semi-Riemannian geometry on Heisenberg-type groups

Subsea pump vibration analysis for predictive maintenance
(Master thesis, 2015-11-29)The goal of this study is to compare vibration signals of subsea pumps from two different time periods. These signals are gathered for predictive maintenance reasons. Vibration analysis is one of the most efficient tools ... -
SUCCESS: SUbsurface CO2 storage–Critical elements and superior strategy
(Peer reviewed; Journal article, 2011)SUCCESS is a Center for Environmental Energy Research in Norway and performs research related to geological storage of CO2 in the subsurface. The SUCCESS centre is established by the Research Council of Norway together ... -
Sudden wave flooding on steep rock shores: a clear but hidden danger
(Journal article; Peer reviewed, 2024)It is shown that very steep coastal profiles can give rise to unexpectedly large wave events at the coast. We conduct a statistical analysis of runs from a nearshore Boussinesq-type model to demonstrate that under certain ... -
Supervised Continuous Max-flow for Segmentation of Images with Intensity Inhomogeneities
(Master thesis, 2016-05-26)In this thesis we propose a regional adaptive active contour model for segmenting images with intensity inhomogeneities effectively. This model includes a regularization term, a global energy term and a local energy term. ... -
Sur la distance à l'instabilité de polynômes matriciels quadratiques / On the distance to instability of quadratic matrix polynomials
(Peer reviewed; Journal article, 2019-06-27)A bisection method is developed for computing the distance to instability of quadratic matrix polynomials. The computation takes rounding errors into account. -
Sur le transport de masse produit par des oscillations en milieu compressible, dissipatif et inhomogène
(Department of Applied Mathematics report, Research report, 1972-12) -
Surface reconstruction Using Probability Based Photo-Consistency
(Master thesis, 2009-12-04)We reconstruct the surface of an object seen from many different angles. We construct an energy functional by using visibility constraints and photo-consistency. This is then solved by the piecewise constant level set method.
