On Curvature and Separability in Unconstrained Optimisation
(Doctoral thesis, 2006-06-16) -
On cutwidth parameterized by vertex cover
(Peer reviewed; Journal article, 2014-04)We study the CUTWIDTH problem, where the input is a graph G, and the objective is find a linear layout of the vertices that minimizes the maximum number of edges intersected by any vertical line inserted between two ... -
On Dasgupta’s Hierarchical Clustering Objective and Its Relation to Other Graph Parameters
(Journal article; Peer reviewed, 2021)The minimum height of vertex and edge partition trees are well-studied graph parameters known as, for instance, vertex and edge ranking number. While they are NP-hard to determine in general, linear-time algorithms exist ... -
On decoding additive generalized twisted Gabidulin codes
(Journal article; Peer reviewed, 2020)In this paper, we consider an interpolation-based decoding algorithm for a large family of maximum rank distance codes, known as the additive generalized twisted Gabidulin codes, over the finite field Fqn for any prime ... -
On Derivative-Free Optimisation Methods
(Master thesis, 2023-05-15)As part of the field of mathematical optimisation, derivative-free optimisation is the study of optimisation methods that are not granted full access to the derivative of the objective function. In this master's thesis, ... -
On dynamical downscaling of ENSO-induced oceanic anomalies off Baja California Peninsula, Mexico: role of the air-sea heat flux
(Journal article; Peer reviewed, 2023)The El Niño Southern Oscillation (ENSO) phenomenon is responsible for important physical and biogeochemical anomalies in the Northeastern Pacific Ocean. The event of 1997-98 has been one of the most intense in the last ... -
On effect of wave breaking on short wind waves
(Peer reviewed; Journal article, 2004-10)The paper presents an attempt to estimate short wave generation by wave breaking. A breaking wave crest disturbs the surface and generates sub-surface turbulence. The locally disturbed area further disperses and feeds short ... -
On Energy Conversion in a Sigma coordinate Oceaan Model
(Department of Applied Mathematics report, Research report, 1999-08) -
On equivalence between known families of quadratic APN functions
(Journal article; Peer reviewed, 2020)This paper is dedicated to a question whether the currently known families of quadratic APN polynomials are pairwise different up to CCZ-equivalence. We reduce the list of these families to those CCZ-inequivalent to each ... -
On Existence and Admissibility of Singular Solutions for Systems of Conservation Laws
(Journal article; Peer reviewed, 2022)A weak notion of solution for systems of conservation laws in one dimension is put forward. In the framework introduced here, it can be shown that the Cauchy problem for any n×n system of conservation laws has a solution. ... -
On Extremal Bases for the h-range Problem, I
(Department of Pure Mathematics report no. 53, Research report, 1989-11) -
On Extremal Bases for the h-range Problem, II
(Department of Pure Mathematics report no. 55, Research report, 1990-02) -
On extremal function in one class of mapping with finite distortion
(Master thesis, 2017-07-26) -
On flow properties of surface waves described by model equations of Boussinesq type
(Doctoral thesis, 2012-03-23) -
On freshwater and the density-driven circulation in the northern seas
(Doctoral thesis, 2017-11-29)The Arctic Ocean and the Nordic Seas are freshening, in part due to anthropogenic climate change. Within the northern seas, seawater density is in part dominated by temperature, and in part by salinity. This reflects on ... -
On generalized algebraic theories and categories with families
(Journal article; Peer reviewed, 2021)We give a syntax independent formulation of finitely presented generalized algebraic theories as initial objects in categories of categories with families (cwfs) with extra structure. To this end, we simultaneously define ... -
On giant shoulders: how a seamount affects the microbialcommunity composition of seawater and sponges
(Journal article; Peer reviewed, 2020)Seamounts represent ideal systems to study the influence and interdependency of environmental gradients at a single geographic location. These topographic features represent a prominent habitat for various forms of life, ... -
On how the power supply shapes microbial survival
(Journal article; Peer reviewed, 2021)Understanding how environmental factors affect microbial survival is an important open problem in microbial ecology. Patterns of microbial community structure have been characterized across a wide range of different ... -
On integration of rock physics in quantitative seismic interpretation
(Doctoral thesis, 2017-01-23) -
On interpolation-based decoding of a class of maximum rank distance codes
(Journal article; Peer reviewed, 2021)In this paper we present an interpolation-based decoding algorithm to decode a family of maximum rank distance codes proposed recently by Trombetti and Zhou. We employ the properties of the Dickson matrix associated with ...
