  2. 21. From experiments with images to 3D models

    Author : Henrike Häbel; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; colloidal particle aggregation; Anisotropy; mass transport; image analysis; Gibbs point processes; porous polymer blended films; porous polymer blended films;

    Abstract : For developing the next generation sustainable materials, it is often crucial to understand and control their properties and function. This work presents cross-disciplinary research starting with experimentally fabricated porous soft biomaterials and images of their micro-structure obtained by electron or laser microscopy.

  4. 22. Topics on Generative Models in Machine Learning

    Author : Carl Ringqvist; Henrik Hult; Thomas Schön; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Latent variable models have been extensively studied within the field of machine learning in recent years. Especially in combination with neural networks and training through back propagation, they have proven successful for a variety of tasks; notably sample gener- ation, clustering, disentanglement and interpolation.

  5. 23. Geometrical and percolative properties of spatially correlated models

    Author : Olof Elias; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; continuum percolation; brownian excursions; brownian interlacements; poisson cylinder model; fractal percolation;

    Abstract : This thesis consists of four papers dealing with phase transitions in various models of continuum percolation. These models exhibit complicated dependencies and are generated by different Poisson processes. For each such process there is a parameter, known as the intensity, governing its behavior. READ MORE

  6. 24. Gene expression profiling in animal models of alcoholism

    Author : Christina Arlinde; Karolinska Institutet; Karolinska Institutet; []
    Keywords : Alcoholism; gene expression; microarray; animal model; rat; brain;

    Abstract : Genetic and environmental factors in alcoholism interact at the level of the transcriptome to encode the phenotypic traits of this complex clinical syndrome. Because of this, the prospect of simultaneous, genome wide, high-throughput analysis of gene expression in key brain areas potentially offers a novel strategy to identify new molecular treatment targets in this disease.

  7. 25. Charged particle distributions and robustness of the neural network pixel clustering in ATLAS

    Author : Edvin Sidebo; Jonas Strandberg; Bengt Lund-Jensen; David Silvermyr; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; p p: scattering; ATLAS; LHC; charged particle: multiplicity; semiconductor detector: pixel; neural network: performance; track data analysis: cluster; charged particle: cluster; splitting; CERN LHC Coll; Fysik; Physics;

    Abstract : This thesis contains a study of the robustness of the artificial neural network used in the ATLAS track reconstruction algorithm as a tool to recover tracks in dense environments. Different variations, motivated by potential discrepancies between data and simulation, are performed to the neural network’s input while monitoring the corresponding change in the output. READ MORE
