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, ...
Subshifts with Simple Cellular Automata
(Turku Centre for Computer Science, 2014-06-28)
A subshift is a set of in nite one- or two-way sequences over a xed nite set, de ned by a set of forbidden patterns. In this thesis, we study subshifts in the topological setting, where the natural morphisms between ...
Order-Theoretic Methods for Space-Time Coding: Symmetric and Asymmetric Designs
(Turku Centre for Computer Science, 2009-01-09)
On Identifying and Locating-Dominating Codes
(Turku Centre for Computer Science, 2011-06-22)
On Distributed Storage Codes
(Turku Centre for Computer Science, 2015-02-13)
Distributed storage systems are studied. The interest in such system has become relatively wide due to the increasing amount of information needed to be stored in data centers or different kinds of cloud systems. There are ...
On The Mean Square of Quadratic Dirichlet L-Functions at 1

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 ...
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 ...
Rich Words and Balanced Words
(Turku Centre for Computer Science, 2016-09-23)
This thesis is mostly focused on palindromes. Palindromes have been studied extensively, in recent years, in the field of combinatorics on words.Our main focus is on rich words, also known as full words. These are words ...
