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, ...
Deﬁning Contexts in Context-Free Grammars
(Turku Centre for Computer Science, 2015-09-25)
This thesis introduces an extension of Chomsky’s context-free grammars equipped with operators for referring to left and right contexts of strings.The new model is called grammar with contexts. The semantics of ...
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 ...
Order-Theoretic Methods for Space-Time Coding: Symmetric and Asymmetric Designs
(Turku Centre for Computer Science, 2009-01-09)
Statistical Methods for Conservation and Alignment Quality in Proteins
(Turun yliopistoAnnales Universitatis Turkuensis AII 228, 2008-11-07)
Construction of multiple sequence alignments is a fundamental task in Bioinformatics. Multiple sequence alignments are used as a prerequisite in many Bioinformatics methods, and subsequently the quality of such methods can ...
Qualitative Characteristics and Quantitative Measures of Solution's Reliability in Discrete Optimization: Traditional Analytical Approaches, Innovative Computational Methods and Applicability
(Turun yliopistoAnnales Universitatis Turkuensis A I 451, 2012-12-18)
The purpose of this thesis is twofold. The first and major part is devoted to sensitivity analysis of various discrete optimization problems while the second part addresses methods applied for calculating measures of ...
Hyperbolic type metrics and distortion of quasiconformal map pings
(Turun yliopistoAnnales Universitatis Turkuensis A I 462, 2013-05-23)
This Ph.D. thesis consists of four original papers. The papers cover several topics from geometric function theory, more specifically, hyperbolic type metrics, conformal invariants, and the distortion properties of ...
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 ...
Adaptive Dynamics of Resource Specialization
(Turun yliopistoAnnales Universitatis Turkuensis A I 508, 2015-03-13)
Ecological specialization in resource utilization has various facades ranging from nutritional resources via host use of parasites or phytophagous insects to local adaptation in different habitats. Therefore, the evolution ...
Garbling Schemes and Applications
(Turku Centre for Computer Science, 2017-03-17)
The topic of this thesis is garbling schemes and their applications. A garbling scheme is a set of algorithms for realizing secure two-party computation. A party called a client possesses a private algorithm ...
