(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Excitable biological cells, such as cardiac muscle cells, can exhibit complex patterns of oscillations such as spiking and bursting. Moreover, it is well known that an enhancement in calcium currents may yield certain kind ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Early afterdepolarizations (EADs) are pathological voltage oscillations during the repolarization phase of cardiac action potentials. They are considered as potential precursors to cardiac arrhythmias and have recently ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2022)In a railway network, a deadlock occurs when two or more trains are preventing each other from moving forward by each occupying the tracks required by the other. Deadlocks are rare but pernicious events in railroad operations, ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)This is a report of an analysis of some of the data generated by a national survey of teaching approaches used in higher education mathematics courses. The overall purpose of the survey was to explore how widespread is the ...

(Master thesis / Masteroppgave, 2017)Conventional 2D medical ultrasound imaging is based on analyzing the backscatter (echoes) from multiple, focused, transmitted acoustic beams. Most imaging systems are very similar in the way they create and record beams. ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2019)Wind dispersal of seeds is an essential mechanism for plants to proliferate and to invade new territories. In this paper we present a methodology used in our recent work [Rabault, Fauli, and Carlson, Phys. Rev. Lett. 122, ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2023)Rayleigh–Bénard convection (RBC) is a recurrent phenomenon in a number of industrial and geoscience flows and a well-studied system from a fundamental fluid-mechanics viewpoint. In the present work, we conduct numerical ...
-
(Master thesis / Masteroppgave, 2013)Introduction: An aneurysm is an acquired, abnormal dilation of a blood vessel. Computational fluid dynamics (CFD) have been used to try and understand this phenomena. CFD studies use assumptions in the simulation model and ...
-
(Master thesis / Masteroppgave, 2017)The mechanical behavior of the heart has been modeled for decades by using continuum mechanics and numerical methods. A widely used, but rarely discussed, assumption is that inertial effects can be neglected in these models. ...

(Master thesis / Masteroppgave, 2021)In regression problems, it is often of interest to assume that the relationship between a predictor variable and a response variable is monotone. In this thesis, we focus on general additive regression, in which each ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2020)Sediment slumps are known to have generated important tsunamis such as the 1998 Papua New Guinea (PNG) and the 1929 Grand Banks events. Tsunami modellers commonly use solid blocks with short run-out distances to simulate ...
