This thesis considers a class of propositional boolean formulas on which various problems related to satisfiability are efficiently solvable by a dynamic programming algorithm. It mainly consists of two larger parts: the ...
Master thesis
• #### Towards Correct Modelling and Model Transformation in DPF ﻿

(The University of Bergen, 2016-06-14)
Model-driven engineering (MDE) is a model-centric software development methodology. It promotes models as first-class entities in software de- velopment. Models are used to represent software along software devel- opment ...
Doctoral thesis
• #### Using Smart Cards to Mitigate Security Threats on Mobile Devices ﻿

(The University of Bergen, 2016-05-31)
This master thesis developed and tested the idea that smart cards are able to help mitigate security threats on mobile devices that are handling sensitive data. Investigating the limitations of smart cards is a fundamental ...
Master thesis
• #### MultiPath TCP-communication (in NorNet Core) ﻿

(The University of Bergen, 2016-05-31)
Technology is constantly evolving, and we are currently witnessing a digital revolution with a tremendous growth of interconnected devices. The scale of the Internet and the amount of transported data is constantly ...
Master thesis
• #### Incompleteness of the Inference System BNeg ﻿

(The University of Bergen, 2016-05-31)
Any propositional discourse can be represented as a propositional theory in a specific form in such a way that the theory is inconsistent if and only if the discourse is paradoxical. Propositional theories in this form ...
Master thesis
• #### SelGenes: a tool for selecting marker genes in heterogeneous samples ﻿

(The University of Bergen, 2016-05-31)
SelGenes is a tool for selecting marker genes for the dominating cell type in heterogeneous samples. Based on a framework from an existing algorithm, SelGenes selects cell-type specific marker genes for the dominating ...

• #### A 43k Kernel for Planar Dominating Set using Computer-Aided Reduction Rule Discovery ﻿

(The University of Bergen, 2016-02-15)
In this thesis we explore the technique of Region Decomposition for finding kernels for Planar Dominating Set. We redefine some concepts used in earlier work, fixing some ambiguities on the way. From those concepts we ...
Master thesis
• #### Output-Sensitive Filtering of Streaming Volume Data ﻿

(John Wiley & Sons Ltd, 2016-02)
Real-time volume data acquisition poses substantial challenges for the traditional visualization pipeline where data enhancement is typically seen as a pre-processing step. In the case of 4D ultrasound data, for instance, ...
Journal article
• #### Case Studies in Constructive Mathematics ﻿

(The University of Bergen, 2016-01-22)
The common theme in this thesis is the study of constructive provability: in particular we investigate aspects of ﬁnite sets and Kan simplicial sets from a constructive perspective. There are numerous deﬁnitions of ...
Doctoral thesis
• #### Statistical and Algebraic Properties of DES ﻿

(Springer, 2016)
D. Davies and S. Murphy found that there are at most 660 different probability distributions on the output from any three adjacent S-boxes after 16 rounds of DES. In this paper it is shown that there are only 72 different ...
Chapter
• #### Parameterized Graph Modification Algorithms ﻿

(The University of Bergen, 2015-12-10)
Graph modification problems form an important class of algorithmic problems in computer science. In this thesis, we study edge modification problems towards classes related to chordal graphs, with the main focus on trivially ...
Doctoral thesis
• #### Independent Set on P5-free graphs, an empirical study ﻿

(The University of Bergen, 2015-11-20)
We implement the recent polynomial time algorithm for the independent set problem on P5-free graphs, and study the performance of this algorithm on graphs of size up to 50. Our empirical results show that the algorithm ...
Master thesis
• #### Efforts towards accessible and reliable bioinformatics ﻿

(The University of Bergen, 2015-11-19)
The aim of the presented work was contributing to making scientific computing more accessible, reliable, and thus more efficient for researchers, primarily computational biologists and molecular biologists. Many approaches ...
Doctoral thesis

(The University of Bergen, 2015-11-18)
This master thesis has been performed at the Department of Informatics, University of Bergen between February and November 2015. The work has been supervised by Professor Matthew G. Parker as a part of the research interest ...
Master thesis
• #### Towards a Secure Framework for mHealth. A Case Study in Mobile Data Collection Systems ﻿

(The University of Bergen, 2015-11-05)
The rapid growth in the mobile communications technology and wide cellular coverage created an opportunity to satisfy the demand for low-cost health care solutions. Mobile Health (a.k.a. mHealth) is a promising health ...

• #### Additive Schwarz preconditioner for the finite volume element discretization of symmetric elliptic problems ﻿

(Springer Netherlands, 2015-09-25)
A symmetric and a nonsymmetric variant of the additive Schwarz preconditioner are proposed for the solution of a class of finite volume element discretization of the symmetric elliptic problem in two dimensions, with large ...
