(Master thesis / Masteroppgave, 2008)This paper is compilated as a masters degree assignment at the Faculty of Mathematics and Natural Science, University of Oslo. Today, Bubble Deck is used to reduce the net weight of a concrete slab. This is done by casting ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2016)In the Barents Sea and adjacent water, fishing grounds are closed for shrimp fishing by the Norwegian Directorate of Fisheries Monitoring and Surveillance Service (MSS) if the expected number of juvenile fish caught are ...
-
(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2017)Knowledge about how many fish that have been killed due to bycatch is an important aspect of ensuring a sustainable ecosystem and fishery. We introduce a Bayesian spatio-temporal prediction method for historical bycatch ...

(Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2018)For a tropical manifold of dimension n we show that the tropical homology classes of degree (n-1, n-1) which arise as fundamental classes of tropical cycles are precisely those in the kernel of the eigenwave map. To prove ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2021)We establish variants of the Lefschetz section theorem for the integral tropical homology groups of tropical hypersurfaces of tropical toric varieties. It follows from these theorems that the integral tropical homology ...

(Research report / Forskningsrapport, 2009)We study the robustness of the sensitivity with respect to parameters in expectation functionals with respect to various approximations of a Lévy process. As sensitivity parameter, we focus on the delta of an European ...
-
(Research report / Forskningsrapport, 2006)This paper proposes a general non-Gaussian Ornstein-Uhlenbeck model for a joint financial process based on marginal Lévy measures joined by a Lévy copula. Simulated processes then result from choices of marginal measures ...
-
(Master thesis / Masteroppgave, 2019)An extended LIBOR forward rate model is derived through what we call the HJM-Lévy framework. The resulting model is a geometric Itô-Lévy process, of which the well known geometric Brownian motion with deterministic volatility ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2016)libRadtran is a widely used software package for radiative transfer calculations. It allows one to compute (polarized) radiances, irradiance, and actinic fluxes in the solar and thermal spectral regions. libRadtran has ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)We prove Lieb type convexity and concavity results for trace functionals associated with positive operator monotone (decreasing) functions and certain monotone concave functions, together with strictly positive linear maps ...
-
(Master thesis / Masteroppgave, 2012)This master's thesis studies the kayak rudder flow phenomena and uses analytic, numerical and experimental methods to describe the force coefficients of kayak rudders. Also an analysis of the sport of flatwater kayaking ...

(Master thesis / Masteroppgave, 2021)In statistical analysis of data we are interested in understanding or estimating certain aspects of the probability distribution generating the data. The aspects we are interested in does not always relate to all the ...
-
(Master thesis / Masteroppgave, 2020)Statistical boosting is a powerful tool that has become increasingly more popular in recent years. It works very well in the high-dimensional data setting, and it has many beneficial properties, e.g., shrinkage, automated ...
