Hierarchy and Expansiveness in Two-Dimensional Subshifts of Finite Type
(Turku Centre for Computer Science, 2016-03-11)
Subshifts are sets of configurations over an infinite grid defined by a set of forbidden patterns. In this thesis, we study two-dimensional subshifts offinite type (2D SFTs), where the underlying grid is Z2 and the ...
Efficient Optimization Algorithms for Nonlinear Data Analysis
(Turku Centre for Computer Science, 2014-12-05)
Identification of low-dimensional structures and main sources of variation from multivariate data are fundamental tasks in data analysis. Many methods aimed at these tasks involve solution of an optimization problem. Thus, ...
Conservation Laws in Cellular Automata
(Turku Centre for Computer Science, 2009-04-17)
Conservation laws in physics are numerical invariants of the dynamics of a system. In cellular automata (CA), a similar concept has already been defined and studied. To each local pattern of cell states a real value is ...

On Identifying and Locating-Dominating Codes in the Infinite King Grid
(Turku Centre for Computer Science, 2012-12-13)
Word Equations and Related Topics. Independence, Decidability and Characterizations
(Turku Centre for Computer Science, 2012-05-18)
The three main topics of this work are independent systems and chains of
word equations, parametric solutions of word equations on three unknowns,
and unique decipherability in the monoid of regular languages.
The ...
Numbers and Languages
(Turku Centre for Computer Science, 2013-03-15)
The thesis presents results obtained during the authors PhD-studies. First systems of language equations of a simple form consisting of just two equations are proved to be computationally universal. These are systems over ...
Stability Analysis in Multicriteria Discrete Portfolio Optimization.
(Turun yliopistoAnnales Universitatis Turkuensis A I 507, 2015-02-20)
Almost every problem of design, planning and management in the technical and organizational systems has several conflicting goals or interests. Nowadays, multicriteria decision models represent a rapidly developing area ...
On Short Exponential Sums Involving Fourier Coefficients of Holomorphic Cusp Forms
(Turku Centre for Computer Science, 2008-05-05)
By an exponential sum of the Fourier coefficients of a holomorphic cusp form we mean the sum which is formed by first taking the Fourier series of the said form,then cutting the beginning and the tail away and considering ...
Extracting information from high-throughput gene expression data with pathway analysis and deconvolution
(Turun yliopisto, 2022-05-06)
Modern technologies allow for the collection of large biological datasets that can be utilised for diverse health-related applications. However, to extract useful information from such data, computational methods are needed. ...
