Dynamics of the N-fold Pendulum in the Framework of Lie Group Integrators
(Peer reviewed; Journal article, 2022)Since their introduction, Lie group integrators have become a method of choice in many application areas. Various formulations of these integrators exist, and in this work we focus on Runge-Kutta-Munthe-Kaas methods. First, ... -
Dynamics of transcendental Henon maps
(Journal article; Peer reviewed, 2019)The dynamics of transcendental functions in the complex plane has received a significant amount of attention. In particular much is known about the description of Fatou components. Besides the types of periodic Fatou ... -
Dynamics of transcendental hÉnon maps III: Infinite entropy
(Peer reviewed; Journal article, 2021)Very little is currently known about the dynamics of non-polynomial entire maps in several complex variables. The family of transcendental Hénon maps offers the potential of combining ideas from transcendental dynamics in ... -
Dynamics of transcendental Hénon maps-II
(Peer reviewed; Journal article, 2022)Transcendental Hénon maps are the natural extensions of the well investigated complex polynomial Hénon maps to the much larger class of holomorphic automorphisms. We prove here that transcendental Hénon maps always have ... -
Dynamisk programvare som medierende verktøy i matematikkundervisningen
(Master thesis, 2011)Målet med denne studien er å se på elevers bruk av dynamisk programvare i matematikkundervisningen. I den forbindelse er det sett etter hvilke muligheter som åpner seg og hvordan kunnskapen til elevene påvirkes av bruk av ... -
The E_2-term of the K(n)-local E_n-Adams spectral sequence
(Peer reviewed; Journal article, 2016)Let E=Enbe Morava E-theory of height n. In[8]Devinatz and Hopkins introduced the K(n)-local En-Adams spectral sequence and showed that, under certain conditions, the E2-term of this spectral sequence can be identified with ... -
Early gut mycobiota and mother-offspring transfer 2017 Aug 24;5(1):107. doi: 10.1186/s40168-017-0319-x.
(Journal article; Peer reviewed, 2017)Background The fungi in the gastrointestinal tract, the gut mycobiota, are now recognised as a significant part of the gut microbiota, and they may be important to human health. In contrast to the adult gut mycobiota, the ... -
Early Prediction of Cervical Cancer Using Matrix Factorization
(Master thesis, 2020)En av hundre norske kvinner kommer til å utvikle livmorhalskreft innen en alder av 75. Kreften er den tredje mest hyppige blant kvinner i alderen 25 til 49. De nordiske screeningprogramme for livmorhalskreft har en påvist ... -
Ecological dynamics and large scale phenotypic differentiation in density-dependent populations
(Journal article; Peer reviewed, 2019)Spatial differentiation of phenotypes is assumed to be determined by a combination of fluctuating selection producing adaptations to the local environment and a homogenizing effect of migration. We present a model with ... -
The ecological dynamics of the coronavirus epidemics during transmission from outside sources when R0 is successfully managed below one
(Peer reviewed; Journal article, 2021)Since COVID-19 spread globally in early 2020 and was declared a pandemic by the World Health Organization (WHO) in March, many countries are managing the local epidemics effectively through intervention measures that limit ... -
Ecological mechanisms explaining interactions within plant-hummingbird networks: morphological matching increases towards lower latitudes
(Peer reviewed; Journal article, 2020)Interactions between species are influenced by different ecological mechanisms, such as morphological matching, phenological overlap and species abundances. How these mechanisms explain interaction frequencies across ... -
Edge detection and Gabor analysis
(Doktoravhandlinger ved NTNU, 1503-8181; 2011:236, Doctoral thesis, 2011) -
Edge-Detection in Signals using the Continuous Wavelet-Transform.: Edge-Detection in Medical UltraSound Images.
(Master thesis, 2006)Today, UltraSound (US) images are often used in medical examination and surgery. An improvement of the quality of these US-images will lead to many advantages, which is a big motivation for research on this field. One ... -

An education spaces framework to define interactive and collaborative practices over the physical-hybrid-virtual continuum.
(Peer reviewed; Journal article, 2021)A new industrial revolution is slowly affecting our social, political, economic, and cultural lives. A fusion of technologies and research is emerging within several fields such as robotics, artificial intelligence, the ... -
Effect of Briefing on Acupuncture Treatment Outcome Expectations, Pain, and Adverse Side Effects among Patients with Chronic Low Back Pain: A Randomized Clinical Trial
(Peer reviewed; Journal article, 2021)Importance: In observational studies, patients’ treatment outcome expectations have been associated with better outcomes (ie, a placebo response), whereas concerns about adverse side effects have been associated with an ... -
Effect of convective mixing process on storage of CO2 in saline aquifers with layered permeability.
(Journal article, 2021)Convective mixing of free-phase CO2 and brine in saline aquifers is an established technique to accelerate the CO2 dissolution process. Correct estimation of the convection onset time and rate of CO2 dissolution into brine ... -
Effect of Safe Failures on the Reliability of Safety Instrumented Systems
(Master thesis, 2008)Safety instrumented systems (SISs) are of prime importance to the process industry to avoid catastrophic consequences or even loss of human life. The dangerous situations that any equipment may face should be analysed in ... -
Effect of turbulence intensity on the performance of an offshore vertical axis wind turbine
(Journal article; Peer reviewed, 2015)Offshore wind energy is one of the most competitive renewable energy resources available to us, which until now been under- exploited. Most of the problems associated with wind farm installation like land acquisition, low ...
