  3. 7. Accurate Finite Difference Methods for Option Pricing

    Författare :Jonas Persson; Lina von Sydow; Per Lötstedt; Johan Tysk; Jari Toivanen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Finite differences; Option pricing; Adaptive methods; Numerical Analysis; Numerisk analys;

    Sammanfattning : Stock options are priced numerically using space- and time-adaptive finite difference methods. European options on one and several underlying assets are considered. These are priced with adaptive numerical algorithms including a second order method and a more accurate method. LÄS MER

  4. 8. Bandwidth-reduced Linear Models of Non-continuous Power System Components

    Författare :Jonas Persson; Lennart Söder; Liisa Haarla; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Linearization methods; frequency analysis; transient analysis; time-domain simulations; eigenvalues; linear analysis; TCSC; Electric power engineering; Elkraftteknik;

    Sammanfattning : Denna avhandling är fokuserad på modellering av elkraftsystemkomponenter och deras representation vid simuleringar av elkraftsystem. Avhandlingen jämför olika linjäriseringstekniker. Dessa tekniker är såväl numeriska som analytiska och används vid linjärisering av ett dynamiskt system. LÄS MER

  5. 9. Brain activity associated with episodic memory : similarities and differences between encoding and retrieval

    Författare :Jonas Persson; Umeå universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Episodic memory; encoding; retrieval; positron emission tomography PET ; enactment; overlap; retrieval mode; retrieval success; novelty;

    Sammanfattning : Understanding the mnemonic functions of the brain has been extensively facilitated by the development of functional neuroimaging techniques such as positron emission tomography (PET) and functional magnetic resonance imaging (fMRI). The present thesis aims at investigating the neural mechanisms underlying memory for personally experienced events (episodic memory), using PET. LÄS MER

  7. 10. Food Quality Effects on Zooplankton Growth and Energy Transfer in Pelagic Freshwater Food Webs

    Författare :Jonas Persson; Tobias Vrede; Peter Eklöv; Ellen van Donk; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Ecology; elemental stoichiometry; phosphorus; polyunsaturated fatty acids; EPA; oligotrophic lakes; empirical modelling; Daphnia; Cladocera; Copepoda; Ekologi;

    Sammanfattning : Poor food quality can have large negative effects on zooplankton growth and this can also affect food web interactions. The main aims of this thesis were to study the importance of different food quality aspects in Daphnia, to identify potentially important differences among zooplankton taxa, and to put food quality research into a natural context by identifying the importance of food quality and quantity in lakes of different nutrient content.
