  1. 1. Rare-event simulation with Markov chain Monte Carlo

    Author : Thorbjörn Gudmundsson; Henrik Hult; Ad Ridder; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Tillämpad matematik och beräkningsmatematik; Applied and Computational Mathematics;

    Abstract : Stochastic simulation is a popular method for computing probabilities or expecta- tions where analytical answers are difficult to derive. It is well known that standard methods of simulation are inefficient for computing rare-event probabilities and there- fore more advanced methods are needed to those problems. READ MORE

  2. 2. Interacting Particle Systems: Percolation, Stochastic Domination and Randomly Evolving Environments

    Author : Erik Broman; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Determinantal processes; k-dependence; k-block-factors; percolation; stochastic Ising models; contact process; $ epsilon-$movability; hidden Markov chain; stochastic domination; k-block-factors;

    Abstract : In this thesis we first analyze the class of one-dependent trigonometric determinantal processes and show that they are all two-block-factors. We do this by constructing the two-block-factors explicitly. Second we investigate the dynamic stability of percolation for the stochastic Ising model and the contact process. READ MORE

  3. 3. Analysis of human epidermal Langerhans' cells and allergens with confocal laser scanning microscopy

    Author : Axel Emilson; Karolinska Institutet; Karolinska Institutet; []
    Keywords : 3-D analysis; allergen; allergic contact dermatitis; basal cellcarcinoma; Bet v I; birch; confocal laser scanning microscopy; epidermis; HLA-DR; image analysis; invariant chain; irritant contact dermatitis; Langerhans cell; occlusion; P. orbiculare;

    Abstract : The aim of the thesis was to explore confocal laser scanning microscopy (CLSM) as a tool for 1) quantitative and 3-dimensional (3-D) analysis of the human antigen-presenting Langerhans' cell (LC) in epidermis and 2) for localization of allergens in yeast cells and in birch pollen. Epidermal LCs were investigated after occlusion with patch tests and in basal cell carcinoma (BCC) skin. READ MORE

  4. 4. Khovanov Homology and Link Cobordisms

    Author : Magnus Jacobsson; Oleg Viro; Jan-Erik Roos; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Algebra and geometry; Khovanov homology; Jones polynomial; Link cobordisms; Algebra och geometri; Algebra and geometry; Algebra och geometri;

    Abstract : Khovanov homology associates to any link in three-dimensional space a bigraded chain complex of Z[c]-modules, whose graded Euler characteristic (after normalization) is the Jones polynomial of the link. The complex is invariant up to homotopy equivalence under ambient isotopy of the link. READ MORE

  5. 5. Modeling Music : Studies of Music Transcription, Music Perception and Music Production

    Author : Anders Elowsson; Anders Friberg; Pawel Herman; Anders Askenfelt; Gerhard Widmer; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Music Information Retrieval; MIR; Music; Music Transcription; Music Perception; Music Production; Tempo Estimation; Beat Tracking; Polyphonic Pitch Tracking; Polyphonic Transcription; Music Speed; Music Dynamics; Long-time average spectrum; LTAS; Algorithmic Composition; Deep Layered Learning; Convolutional Neural Networks; Rhythm Tracking; Ensemble Learning; Perceptual Features; Representation Learning;

    Abstract : This dissertation presents ten studies focusing on three important subfields of music information retrieval (MIR): music transcription (Part A), music perception (Part B), and music production (Part C).In Part A, systems capable of transcribing rhythm and polyphonic pitch are described.
