  1. 1. Evolutionary optimisation of a morphological image processor for embedded systems

    Författare :Andreas Magnusson; Högskolan i Borås; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; embedded system; machine vision; morphological image processing; genetic algorithm; Energi och material;

    Sammanfattning : The work presented in this thesis concerns the design, development and implementation of two digital components to be used, primarily, in autonomously operating embedded systems, such as mobile robots. The first component is an image coprocessor, for high-speed morphological image processing, and the second is a hardware-based genetic algorithm coprocessor, which provides evolutionary computation functionality for embedded applications.

  3. 2. Adaptive tensor-based morphological filtering and analysis of 3D profile data

    Författare :Anders Landström; Cris Luengo; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Sammanfattning : Image analysis methods for processing 3D profile data have been investigated and developed. These methods include; Image reconstruction by prioritized incremental normalized convolution, morphology-based crack detection for steel slabs, and adaptive morphology based on the local structure tensor.

  4. 3. Evolution of the G protein-coupled receptor signaling system : Genomic and phylogenetic analyses

    Författare :Arunkumar Krishnan; Helgi Schiöth; Torgeir Hvidsten; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; GPCRs; G proteins; Sensory system; Signal transduction; Olfaction; Chemosensation; Hemichordates; Sponges; Porifera; Bilaterians; Holozoans; Fungi; Opisthokonts; Bioinformatics; Bioinformatik;

    Sammanfattning : Signal transduction pathways mediated by G protein-coupled receptors (GPCRs) and their intracellular coupling partners, the heterotrimeric G proteins, are crucial for several physiological functions in eukaryotes, including humans. This thesis describes a broad genomic survey and extensive comparative phylogenetic analysis of GPCR and G protein families from a wide selection of eukaryotes. LÄS MER

  5. 4. Airway epithelial shedding: Morphological and functional aspects in vivo

    Författare :Jonas Erjefält; Luftvägsinflammation; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; eosinophils; neutrophils; plasma exudation; barrier restitution; basal cells; ciliated cells; secretory cells; Epithelial repair; epithelial shedding; fibrinogen; fibronectin; Respiratory system; Andningsorganen;

    Sammanfattning : Epithelial damage may contribute to the pathology in airway diseases such as asthma and rhinitis. However, the distribution of epithelial shedding in inflammatory airway diseases and, particularly, the ensuing repair processes are largely unknown. LÄS MER

  7. 5. Landerierna i Göteborgs stadsbyggande

    Författare :Gunilla Enhörning; Chalmers tekniska högskola; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; urban morphology; historical map-overlay; Göteborg [Gothenburg]; donation land; morphological system; urban transformations.; town plan and expansion; Landeri ; geographical information systems [GIS]; sub-urban pattern;

    Sammanfattning : This thesis explores the relationship between town planning and the /landerier/* in Göteborg by using historical morphological analysis combined with geographical information systems (GIS). The growth of the /landerier/, gradually leased out after the city foundation in 1621 on the so-called donation land, is analyzed and described. LÄS MER
