Tässä tutkielmassa konstruoidaan minimaalidiskriminanttisia jakoalgebroja. Jakoalgebroja on mahdollista hyödyntää langattomassa tiedonsiirrossa käytettävien ns. aika-avaruuskoodien tuottamisessa. Syy etsiä mahdollisimman ...
From the beginning of set theory to Lebesgue’s measure problem
(Turun yliopisto, 2020-01-16)
Descriptive set theory has its origins in Cantor’s work on pointsets in the 1870s. Cantor’s construction of real numbers and proof of the non-denumerability of real numbers were the first results towards a new theory. ...
Bundle methods in nonsmooth DC optimization
(Turun yliopisto, 2018-06-21)
Due to the complexity of many practical applications, we encounter optimization problems with nonsmooth functions, that is, functions which are not continuously differentiable everywhere. Classical gradient-based methods ...
On using distances to locate vertices: resolving sets and metric bases of graphs, two generalisations and their forced vertices
(Turun yliopisto, 2021-06-18)
A graph consists of vertices that are connected by edges. A resolving set of a graph is a subset of its vertices that gives a unique combination of distances to every vertex of the graph. We can use the distances we are ...
On location, domination and information retrieval
(Turku Centre for Computer Science, 2020-09-25)
The thesis is divided into two main branches: identifying and locatingdominating codes, and information retrieval. The former topics are motivated by the aim to locate objects in sensor networks (or other similar applications) ...

Generalized Orlicz spaces and partial differential equations with application to image restoration
(Turun yliopisto, 2022-11-11)
The research area of this thesis is nonlinear functional analysis, a branch of Mathematics which examines questions related to qualitative aspects of solution of a differential equation, such as existence, uniqueness, ...
Mechanistic population Models in Biology: Model Derivation and Application
(Turun yliopistoAnnales Universitatis Turkuensis AI 400, 2009-09-24)
In general, models of ecological systems can be broadly categorized as ’top-down’ or ’bottom-up’ models, based on the hierarchical level that the model processes are formulated on. The structure of a top-down, also known ...

Conformal invariants
(Turun yliopisto, 2010-05-14)
This master thesis investigates the moduli of families of curves and the capacities of the Gr¨otzsch and Teichm¨uller rings, which are applied in the main parts of this
master thesis. The extremal properties of these rings ...
