S100A4 mRNA-protein relationship uncovered by measurement noise reduction
(Journal article; Peer reviewed, 2020)Intrinsic biological fluctuation and/or measurement error can obscure the association of gene expression patterns between RNA and protein levels. Appropriate normalization of reverse-transcription quantitative PCR (RT-qPCR) ... -
Sammenhenger mellom koder, matroider, grafer og simplisielle komplekser
(Master thesis, 2008)Denne masteroppgaven handler hovedsakelig om å studere sammenhenger mellom ulike em- ner innen algebra og kombinatorikk. De matematiske konseptene som studeres, er lineære koder, matroider, grafer og simplisielle komplekser, ... -
Sampling error distribution for the ensemble Kalman filter update step
(Peer reviewed; Journal article, 2011-07-06)In recent years, data assimilation techniques have been applied to an increasingly wider specter of problems. Monte Carlo variants of the Kalman filter, in particular, the ensemble Kalman filter (EnKF), have gained significant ... -
Samtalekvalitet, strategier og forståelse i arbeid med Elevgenererte eksempler
(Master thesis, 2019-06-22)Jeg har forsket på Elevgenererte eksempler som didaktisk tilnærming i trigonometri i 2 klasser på videregående skole. I den forbindelse har jeg analysert datamaterialet mitt for samtalekvalitet, strategier og forståelse ... -
Samtaletrekk i forbindelse med progresjon i forståelse i matematikk

SBP-SAT schemes for hyperbolic problems
(Master thesis, 2019-06-13)Numerical methods for solving partial differential equations is an important field of study, as it helps us to describe many different processes in the world. An important property of a numerical method, is that it should ... -
Scene Reconstruction Using Level Sets and Graph Cuts
(Master thesis, 2009-07-17) -
Scroll codes over curves of higher genus
(Peer reviewed; Journal article, 2010)We construct linear codes from scrolls over curves of high genus and study the higher support weights di of these codes. We embed the scroll into projective space Pk-1 and calculate bounds for the di by considering the ... -
Sediment Transport and Floods In A Changing Climate
(Master thesis, 2020-06-17)Rainfall intensity and river flood magnitudes in Norway are expected to increase in the near future due to climate change. This thesis investigates the morphological impacts this increase in rainfall intensity will have ... -
Segmentation of data traces with applications to dipmeter oil well measurements
(Statistical report no. 18, Research report, 1988-02) -
Selection for biparental inheritance of mitochondria under hybridization and mitonuclear fitness interactions
(Journal article; Peer reviewed, 2021)Uniparental inheritance (UPI) of mitochondria predominates over biparental inheritance (BPI) in most eukaryotes. However, examples of BPI of mitochondria, or paternal leakage, are becoming increasingly prevalent. Most ... -
Semi-conditional variational auto-encoder for flow reconstruction and uncertainty quantification from limited observations
(Journal article; Peer reviewed, 2021)We present a new data-driven model to reconstruct nonlinear flow from spatially sparse observations. The proposed model is a version of a Conditional Variational Auto-Encoder (CVAE), which allows for probabilistic ... -
Semi-H-type groups and Semi-Damek-Ricci spaces
(Master thesis, 2019-06-22) -
Semiparametric model selection for copulas
(Master thesis, 2013-06-03)This thesis will consider the performance of the cross-validation copula information criterion, xv-CIC, in the realm of finite samples. The theory leading to the xv-CIC will be outlined, and an analysis will be conducted ... -
Sequential Data Assimilation in High Dimensional Nonlinear Systems
(Doctoral thesis, 2011-10-21)Since its introduction in 1994, the ensemble Kalman filter (EnKF) has gained a lot of attention as a tool for sequential data assimilation in many scientific areas. Due to its computationally fast and easy to implement ... -

Sequestration of Carbon in Saline Aquifers Mathematical and Numerical Analysis
(Doctoral thesis, 2004-04-30)The work in this thesis focuses equally on two main topics. The first of these subjects deals with development of criteria for monotonicity of con- trol volume methods. These methods are important and frequently used for ... -
Sexual dimorphism in the familial aggregation of tinnitus
(Journal article; Peer reviewed, 2020-11)Twin and adoption studies point towards a genetic contribution to tinnitus; however, how the genetic risk applies to different forms of tinnitus is poorly understood. Here, we perform a familial aggregation study and ... -
The Sibling Distribution for Multivariate Life Time Data
(Journal article; Peer reviewed, 2021)A flexible class of multivariate distributions for continuous lifetimes is proposed. The distribution is defined in terms of the age-at-death of m siblings. The expression for the joint density is derived using classical ... -
Sigma coordinate pressure gradient errors and the basin problem
(Master thesis, 2010-04-15)This work will focus on how the internal pressure gradient errors affect the numerical instability in idealised ocean basins. The nature of the errors will be investigated and discussed. First, in Chapter 1, the ocean model ...
