(Master thesis, 2006)Oppgaven dreier seg om den nasjonale prøven i matematikk 1MX som ble gjennomført den 15. april 2005. Fokus er rettet mot de oppgavene i prøvesettet som hadde til hensikt å måle elevens kompetanse innenfor representasjoner, ... -
New applications of extremely regular function spaces
(Peer reviewed; Journal article, 2019)Let L be an infinite locally compact Hausdorff topological space. We show that extremely regular subspaces of C0(L) have very strong diameter 2 properties and, for every real number ε with 0 <ε<1, contain an ε-isometric ... -
Newton og Leibniz´ arbeid med utviklingen av kalkulus sett i lys av dagens lærebøker : med spesiell vekt på hovedteoremet i kalkulus og regnemåter
(Master thesis, 2010)I denne oppgaven har jeg arbeidet med den historiske kalkulusen til Newton og Leibniz og sammenliknet den med tilsvarende kapitler i norske lærebøker. Jeg har lagt spesielt vekt på måten hovedteoremet i kalkulus blir ... -
Nivådelt undervisningsopplegg i grunnkurs i matematikk for økonomistudenter : en undersøkelse
(Master thesis, 2008)Målet med denne masteroppgaven var å undersøke et nivådelt undervisningsopplegg i grunnkurs matematikk for økonomistudenter. Nivådelingen var basert på studentenes egne oppfatninger av hvor gode matematikk kunnskaper de ... -
Non-homogeneous continuous time Markov chain model for information dissemination on Indonesian Twitter users
(Peer reviewed; Journal article, 2023)Nonhomogeneous Continuous-Time Markov Chain (NH-CTMC) is a stochastic process that can be used to model problems where the future state depends only on the current state and is independent of the past. The transition ... -
A Non-normal-Mode Marginal State of Convection in a Porous Rectangle
(Journal article; Peer reviewed, 2019)The fourth-order Darcy–Bénard eigenvalue problem for onset of thermal convection in a 2D rectangular porous box is investigated. The conventional type of solution has normal-mode dependency in at least one of the two spatial ... -

The object-tool duality in mathematical modelling - a framework to analyze students’ appropriation of Sankey diagrams to model dynamic processes
(Peer reviewed; Journal article, 2020)Students often do not experience the relevance of learning mathematics. This paper reports on an exploratory case study, in which a class of grade 8 students (n=35) was introduced to Sankey diagrams. The aim was to explore ... -
Omvendt undervisning i matematikk : en studie av elevers oppfatning av undervisningsmetoden
(Master thesis, 2013)Many teachers want to try out different teaching methods to find the one that makes students learn best. In today's society we surround ourselves with technology most of the day and there are several teaching methods that ... -
On concept images of monotonicity of Finnish secondary students – with comparison and reference to tertiary students
(Master thesis, 2017)This study is titled “On concept images of monotonicity of Finnish secondary students – with comparison and reference to tertiary students”. The aim is to examine: (1) What kind of aspects of monotonicity are present and, ... -
On Daugavet indices of thickness
(Peer reviewed; Journal article, 2021)Inspired by R. Whitley's thickness index the last named author recently introduced the Daugavet index of thickness of Banach spaces. We continue the investigation of the behavior of this index and also consider two new ... -

On stability of linear dynamic systems with hysteresis feedback
(Journal article; Peer reviewed, 2020)The stability of linear dynamic systems with hysteresis in feedback is considered. While the absolute stability for memoryless nonlinearities (known as Lure’s problem) can be proved by the well-known circle criterion, the ... -

On the asymptotic behavior of solutions to a class of third-order nonlinear neutral differential equations
(Peer reviewed; Journal article, 2020)By using comparison principles, we analyze the asymptotic behavior of solutions to a class of third-order nonlinear neutral differential equations. Due to less restrictive assumptions on the coefficients of the equation ... -

On the thermal instability in a horizontal rectangular porous channel heated from below by a constant flux
(Journal article; Peer reviewed, 2014)The onset of thermoconvective instability in a rectangular horizontal channel filled with a fluid-saturated porous medium is studied. The channel is heated from below with a constant flux. The top wall is maintained at a ...
