Applications of Max-Plus Algebra to Scheduling
(Åbo Akademis förlag - Åbo Akademi University Press, 12.05.2021)Max-plus algebra provides mathematical theory and techniques for solving nonlinear problems that can be given the form of linear problems, when arithmetical addition is replaced by the operation of maximum and arithmetical ... -
Boundary identification in the domain of a parabolic partial differential equation
(Åbo Akademi - Åbo Akademi University, 16.01.2009)Bakgrunden och inspirationen till föreliggande studie är tidigare forskning i tillämpningar på randidentifiering i metallindustrin. Effektiv randidentifiering möjliggör mindre säkerhetsmarginaler och längre serviceintervall ... -
Different Types of Weighted Composition Operators on Banach Spaces of Analytic Functions
(Åbo Akademi - Åbo Akademi University, 26.05.2023)Many problems in real life are, at least approximatively, of linear nature and can be mathematically examined with the aid of linear spaces. It is natural to measure the size of objects occurring in the problems and such ... -
Economic capital allocation
(Åbo Akademi - Åbo Akademi University, 04.03.2016)For my Licentiate thesis, I conducted research on risk measures. Continuing with this research, I now focus on capital allocation. In the proportional capital allocation principle, the choice of risk measure plays a very ... -
Excessive functions, Appell polynomials and optimal stopping
(Åbo Akademi - Åbo Akademi University, 15.05.2014)The main topic of the thesis is optimal stopping. This is treated in two research articles. In the first article we introduce a new approach to optimal stopping of general strong Markov processes. The approach is based ... -
Exit times for some processes with normally distributed noise
(Åbo Akademi - Åbo Akademi University, 31.10.2014)Denna avhandling handlar om metoder för att hitta begränsningar för det asymptotiska beteendet hos en förväntad uthoppstid från ett område omkring en xpunkt för processer som har normalfördelad störning. I huvudsak behandlas ... -
Explicit results in theory of zeros and prime numbers
(Åbo Akademi - Åbo Akademi University, 28.08.2020)This thesis is comprised of three articles in which we prove explicit estimates for different number theoretical problems.In the first article we derive an explicit Riemann-von Mangoldt formula for the Selberg class ... -
Fuzzy real option analysis in patent related decision making and patent valuation
(Åbo Akademi - Åbo Akademi University, 12.06.2015)The shift towards a knowledge-based economy has inevitably prompted the evolution of patent exploitation. Nowadays, patent is more than just a prevention tool for a company to block its competitors from developing rival ... -

Hilbert matrix, Volterra and weighted composition operators on Banach spaces of analytic functions
(Åbo Akademi - Åbo Akademi University, 11.12.2020)Avsikten med denna avhandling är att studera två klassiska linjära integraloperatorer, Hilbertmatrisoperatorn H och den generaliserade Volterraoperatorn Tϕg mellan Banachrum av analytiska funktioner på den öppna enhetsdisken ... -
Indoor air quality at a waste incineration plant in Finland
(Åbo Akademi University, 04.09.2013)Waste has been incinerated for energy utilization for more than a hundred years, but the harmful emissions emitted from the incineration plants did not begin to cause concern until the 1980s. Many plants were shutdown and ... -
On the use of convex underestimators in global optimization

The knapsack problem approach in solving partial hedging problems of options
(Åbo Akademis förlag - Åbo Akademi University Press, 31.08.2012)This thesis introduces a new approach for studying the problem of optimal partial hedging of both European and American options in a nite and complete discrete-time market model. We show how certain partial hedging problems, ... -
Three-dimensional fourier analysis of electron microscopy to characterize diffusion tensor imaging data
(Åbo Akademi University, 2016)Diffusion tensor imaging (DTI) is a highly sensitive MRI method that unveils the changes in brain microstructures. By estimating the movement of protons through different areas of complexity in the brain, DTI provides a ... -
Towards input/output-free modelling of linear infinite-dimensional systems in continuous time
