(Doctoral thesis / Doktoravhandling, 2022)One of the biggest open problems in Complex Geometry is whether every open Riemann Surface admits a proper holomorphic embedding into the 2-dimensional euclidean complex space, as this provides a good representation of ...

Properties of Estimators for Cumulative Baseline Hazard from Case-control Studies in the Relative Risk ModelRestricted Access (Master thesis / Masteroppgave, 2012)Sampling techniques such as case-cohort and nested case-control studies, allows us to analyze survival data under the relative risk model assumption, without having to collect data for the full cohort. This can reduce the ...
-
(Master thesis / Masteroppgave, 2010)Nested case-control studies (NCC) reduce the cost of large cohort studies, but are statistically less efficient since all information is only available for cases and controls. In particular in a competing risk situation ...

(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2018)Knowledge about how information is stored in neurons of animals and in the human brain is still incomplete. A hypothesis related to long-term changes in synaptic efficiency has strong experimental support, but does not ...
-
(Master thesis / Masteroppgave, 2021)In this thesis we consider a general stochastic interest rate under the HJM (Heath-Jarrow-Morton) framework. We further present a general model for the pricing of life insurance policies allowing for a wider range of ...

Proxy expenditure weights for Consumer Price Index: Audit sampling inference for big-data statistics (Journal article / Tidsskriftartikkel / AcceptedVersion; Peer reviewed, 2021)Abstract Purchase data from retail chains can provide proxy measures of private household expenditure on items that are the most troublesome to collect in the traditional expenditure survey. Due to the inevitable ...

(Master thesis / Masteroppgave, 2009)An important topic in biomechanical flow is the study of aneurysms. Aneurysm can be found in bifurcation and curved blood vessels. These can rupture leading to life threatening situations. In this thesis we will look at ...
-
(Journal article / Tidsskriftartikkel / PublishedVersion; Peer reviewed, 2022)We developed a novel, pump-less directional flow recirculating organ-on-a-chip (rOoC) platform that creates controlled unidirectional gravity-driven flow by a combination of a 3D-tilting system and an optimized microfluidic ...

(Research report / Forskningsrapport, 2005)The paper introduces the pyramid probability distribution through its density in two dimensions, and investigates its properties and those of its copula. The research focuses on ways in which the pyramid distribution ...
