  1. 1. Multivariate Networks : Visualization and Interaction Techniques

    Författare :Ilir Jusufi; Andreas Kerren; Jessie Kennedy; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Information Visualization; Multivariate Networks; Visual Analytics; Exploration; Interaction; Computer Science; Datavetenskap; Information and software visualization; Informations- och programvisualisering;

    Sammanfattning : As more and more data is created each day, researchers from different science domains are trying to make sense of it. A lot of this data, for example our connections to friends on different social networking websites, can be modeled as graphs, where the nodes are actors and the edges are relationships between them.

  3. 2. Towards the Visualization of Multivariate Biochemical Networks

    Författare :Ilir Jusufi; Andreas Kerren; Heidrun Schumann; Linnéuniversitetet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Information Visualization; Biological Networks; Multivariate Networks; Biological Visualization; Computer Science; Datavetenskap; Information and software visualization; Informations- och programvisualisering;

    Sammanfattning :  Many open challenges exist when dealing with different biological networks. They are crucial for the understanding of living beings. Complete drawings of these typically large networks usually suffer from clutter and visual overload. In order to overcome this issue, the networks are divided into single, hierarchically structured pathways. LÄS MER

  4. 3. Decoding the complex brain : multivariate and multimodal analyses of neuroimaging data

    Författare :Alireza Salami; Lars Nyberg; Cheryl Grady; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; multivariate analysis; univariate analysis; multimodal imaging; episodic memory; aging; functional magnetic resonance imaging; diffusion tensor imaging; biology; biologi; Psychology; psykologi; datoriserad bildanalys; Computerized Image Analysis;

    Sammanfattning : Functional brain images are extraordinarily rich data sets that reveal distributed brain networks engaged in a wide variety of cognitive operations. It is a substantial challenge both to create models of cognition that mimic behavior and underlying cognitive processes and to choose a suitable analytic method to identify underlying brain networks.

  7. 5. On Perfect Simulation of Markovian Queueing Networks with Blocking

    Författare :Dan Mattsson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Markov chain; Monte Carlo methods; Propp-Wilson algorithm; perfect simulation; queueing theory; Jackson networks; birth and death processes; Jackson networks;

    Sammanfattning : Perfect simulation of a class of Markovian queueing networks with finite buffers is examined in this monograph. The network processes defined are modelled by restricted multivariate birth and death processes with intensities depending on a random environment. The random environments are mainly a set of independent onoff processes. LÄS MER
