Analysis of Trivium Using Compressed Right Hand Side Equations
(Chapter; Peer reviewed, 2012)We study a new representation of non-linear multivariate equations for algebraic cryptanalysis. Using a combination of multiple right hand side equations and binary decision diagrams, our new representation allows a very ... -
An Approach for Investigation of Geochemical Rock-Fluid Interactions
(Chapter, 2014)Geochemistry has a substantial impact in exploiting of geothermal systems. When water is injected in a geothermal reservoir, the injected water and in-situ brine have different temperatures and chemical compositions and ... -
Basin Interactions and predictability
(Chapter, 2020) -
Classifying and Measuring Student Problems and Misconceptions
(Norsk informatikkonferanse, Chapter; Peer reviewed, 2013)In this paper we report on an attempt to classify student problems and mistakes, and measuring the frequency of particular problems in a firstsemester programming course. We also propose a scheme for annotating student ... -

Colluding Tags Attack on the ECC-based Grouping Proofs for Rfids
(Chapter, 2012)Recently, a new privacy-preserving elliptic curve based grouping proof protocol with colluding tag prevention( CTP) has been proposed. The CTP protocol is claimed to be resistant against colluding tags attacks in which the ... -
Community Detection on the GPU
(Chapter; Peer reviewed, 2017)We present and evaluate a new GPU algorithm based on the Louvain method for community detection. Our algorithm is the first for this problem that parallelizes the access to individual edges. In this way we can fine tune ... -
A Comparative Analysis of Feature Selection Methods for Biomarker Discovery in Study of Toxicant-Treated Atlantic Cod (Gadus Morhua) Liver
(Communications in Computer and Information Science; 1056, Chapter; Peer reviewed, 2019)Univariate and multivariate feature selection methods can be used for biomarker discovery in analysis of toxicant exposure. Among the univariate methods, differential expression analysis (DEA) is often applied for its ... -
Comparison of Discrete and Continuous Models for the Pooling Problem
(Chapter; Peer reviewed, 2011)The pooling problem is an important global optimization problem which is encountered in many industrial settings. It is traditionally modeled as a bilinear, nonconvex optimization problem, and solved by branch-and-bound ... -
Computational Science in the 17th Century. Numerical Solution of Algebraic Equations: Digit–by–Digit Computation
(Chapter, 2022)In this paper we give a complete overview of test–problems by Viète from 1600, Harriot from 1631 and Oughtred from 1647. The original material is not easily accessible due to archaic language and lack of conciseness. Viéte’s ... -
A Continuous Max-Flow Approach to Minimal Partitions with Label Cost Prior
(Chapter; Peer reviewed, 2011)This paper investigates a convex relaxation approach for minimum description length (MDL) based image partitioning or labeling, which proposes an energy functional regularized by the spatial smoothness prior joint with a ... -
Convective chimneys and plumes in the Northern Greenland Sea
(Geophysical Monograph Series;30, Chapter, 2005)In the Boreas Basin in the northern Greenland Sea, convection has been observed to be localized as narrow structures - chimneys - in which the water masses may be homogeneous from the surface through great depths. An ... -
Coring of unconsolidated permafrost deposits: methodological successes and challenges
(Chapter; Peer reviewed, 2015)This technical note presents three scales of drilling infrastructure for comparison. These three methods include: (1) a small hand-drill designed for retrieving cores down to ca. 5 m depth, (2) the medium-scale UNIS ... -
Cyclic homology in a special world
(Chapter, 2020)In work of Connes and Consani, Γ-spaces have taken a new importance. Segal introduced Γ-spaces in order to study stable homotopy theory, but the new perspective makes it apparent that also information about the unstable ... -
Det regionale i det internasjonale - en internasjonaliseringsstrategi for høyskolene på Vestlandet
(Chapter, 2018)Fra å starte som rene undervisningsinstitusjoner har høyskolene nå fått krav om å være relevante i en forskningssammenheng. Spørsmålet er da – hvordan kan små institusjoner i utkanten av verden operere internasjonalt? Mitt ... -
Differential Fault Analysis of Trivium
(Lecture Notes in Computer Science; 5086, Chapter; Peer reviewed, 2008)Trivium is a hardware-oriented stream cipher designed in 2005 by de Canni`ere and Preneel for the European project eStream, and it has successfully passed the first and the second phase of this project. Its design has a ... -
Direct data transfer between SOAP web services in Orchestration
(Chapter; Peer reviewed, 2012)In scientific data analysis, workflows are used to integrate and coordinate resources such as databases and tools. Workflows are normally executed by an orchestrator that invokes component services and mediates data transport ... -
Domain decomposition preconditioning for non-linear elasticity problems
(Chapter; Peer reviewed, 2014)We consider domain decomposition techniques for a non-linear elasticity problem. Our main focus is on non-linear preconditioning, realized in the framework of additive Schwarz preconditioned inexact Newton (ASPIN) methods. ... -
Effective permeability of deformation bands in fault damage zones – Can deformation bands reduce the risk of fault leakage?
(SINTEF Proceedings;7, Chapter, 2021)Faults are major geological structures that can dominate the flow paths in subsurface reservoirs by, e.g., connecting otherwise unconnected layers. In CO2 storage sites where the faults act as the main structural trap, the ...
