Algebraic Cryptanalysis of Cryptographic Schemes with Extension Field Structure
(Doctoral thesis, 2021-09-06)Post-Quantum Cryptography studies cryptographic algorithms that quantum computers cannot break. Recent advances in quantum computing have made this kind of cryptography necessary, and research in the field has surged over ... -
Algebraic Reasoning About Timeliness
(Journal article; Peer reviewed, 2023)Designing distributed systems to have predictable performance under high load is difficult because of resource exhaustion, non-linearity, and stochastic behaviour. Timeliness, i.e., delivering results within defined time ... -
Algebravansker. Hva er årsaken til at elevene syns algebra er vanskelig? Er det hull i grunnleggende kunnskap og/eller misoppfatninger hos elever på videregående skole som gjør at algebra er vanskelig for dem?
(Master thesis, 2017)I denne oppgaven kommer det fram hva årsaken og problemer elever på videregående kan ha i algebra som gjør at de syns algebra er vanskelig, og gjør det dårlig i dette emnet. Resultatene fra TIMSS Advanced i 2015 viser at ... -
Alginate and tunicate nanocellulose composite microbeads – Preparation, characterization and cell encapsulation
(Journal article; Peer reviewed, 2022)Alginate has been used for decades for cell encapsulation. Cellulose nanofibrils (CNF) from tunicates are desirable in biomedicine due to high molecular weight, purity, crystallinity, and sustainable production. We prepared ... -

Algorithmic Complexity of Clustering and Low-Rank Approximation Problems
(Doctoral thesis, 2021-03-29)The two most popular unsupervised learning problems are k-Clustering and Low-Rank Approximation. Consider a set of n datapoints, in the k-Clustering problem, the objective is to partition these points into k clusters and ... -
An Algorithmic Meta-Theorem for Graph Modification to Planarity and FOL
(Journal article; Peer reviewed, 2020)In general, a graph modification problem is defined by a graph modification operation ⊠ and a target graph property 𝒫. Typically, the modification operation ⊠ may be vertex removal, edge removal, edge contraction, or edge ... -
Algorithms for covering multiple submodular constraints and applications
(Journal article; Peer reviewed, 2022)We consider the problem of covering multiple submodular constraints. Given a finite ground set N, a weight function \(w: N \rightarrow \mathbb {R}_+\), r monotone submodular functions \(f_1,f_2,\ldots ,f_r\) over N and ... -
Algorithms for Linearly Ordered Boolean Formulas
(Master thesis, 2016-06-30)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 ... -
Algorithms for rainbow vertex colouring diametral path graphs

Algorithms for the Rainbow Vertex Coloring Problem on Graph Classes
(Journal article; Peer reviewed, 2020)Given a vertex-colored graph, we say a path is a rainbow vertex path if all its internal vertices have distinct colors. The graph is rainbow vertex-connected if there is a rainbow vertex path between every pair of its ... -
Algoritmisk tenkning og kreativitet
(Master thesis, 2023-06-01)Den raske teknologiutviklingen har ført til at det stadig stilles nye krav til befolkningens kompetanse og ferdigheter. Algoritmisk tenkning og kreativitet anses som essensielle ferdigheter i det 21.århundre. Gjennom ... -
Alias - Designing an application for creating personalised comics aimed for the Children and Youth Clinic at Haukeland University Hospital
(Master thesis, 2019-12)Information that is handed out by hospitals is not always personalised for patients and their motivation is often lacking. Communication between healthcare and patients is mostly textual and verbal, sometimes overwhelming, ... -
ALICE measurement of the \(J/\psi\) nuclear modification factor at mid-rapidity in Pb–Pb collisions at \(\sqrt{{s}_{NN}}=\) 5.02 TeV
(Peer reviewed; Journal article, 2017-11)ALICE at the LHC provides unique capabilities to study charmonium production at low transverse momenta ( p T ). At central rapidity, ( |y|<0.8 ), ALICE can reconstruct J/ ψ via their decay into two electrons down to zero ... -
ALICE measurements of flow coefficients and their correlations in small (pp and p–Pb) and large (Xe–Xe and Pb–Pb) collision systems
(Peer reviewed; Journal article, 2019)Many observables which are used as a signature of the collective effects in heavy-ion collisions when measured in high multiplicity pp and pA interactions reveal a very similar behaviour. We will present first measurements ... -
ALICE results on system-size dependence of charged-particle multiplicity density in p–Pb, Pb–Pb and Xe–Xe collisions
(Peer reviewed; Journal article, 2019)Particle production at LHC energies involves the interplay of hard (perturbative) and soft (non-perturbative) QCD processes. Global observables, such as the charged-particle multiplicity, are related to the initial geometry ... -
ALICE TPC Upgrade Activities for LHC Run 3 and Beyond: "SAMPA ASIC Tests with GEM Detector Prototype"
(Master thesis, 2015-09-11)The Time Projection Chamber (TPC) signal readout of the ALICE detector is being upgraded to accommodate the higher collision rates and -energies during LHC Run 3 in 2018. Due to the increased collision rates, the TPC drift ... -
