  3. 3. Image Based Visualization Methods for Meteorological Data

    University dissertation from Institutionen för teknik och naturvetenskap

    Author : Björn Olsson; Linköpings universitet.; Linköpings universitet.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Visualization; Meteorological Data; Artificial Neural Networks; High-Dynamic-Range images; Satellite Data; Classification; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik Datavetenskap;

    Abstract : Visualization is the process of constructing methods, which are able to synthesize interesting and informative images from data sets, to simplify the process of interpreting the data. In this thesis a new approach to construct meteorological visualization methods using neural network technology is described. READ MORE

  4. 4. Collaborative Visualization Designing and evaluating systems for co-located work

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Lars Winkler Pettersson; Uppsala universitet.; Uppsala universitet.; [2008]
    Keywords : Visualization; Human-Computer Interaction; Collaboration; Co-located Visualization; Computer Supported Cooperative Work;

    Abstract : This thesis investigates new ways of using information visualization to support collaboration in co-located work. To study this phenomenon, Multiple Viewer Display Environments (MVDEs) with independent views have been applied to present information such that all viewers at the same time and in the same display can see correct views of 3D models, see correctly oriented text and see different parts and aspects of information in each view.

  5. 5. Visualization of Causal Relations

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Niklas Elmqvist; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; information visualization; causality visualization; citation network visualization; causal relations;

    Abstract : The notion of cause and effect is pervasive in human thinking and plays a significant role in our perception of time. Software systems, in particular parallel and distributed ones, are permeated by this causality, and the human mind is especially well-suited to detect instances of this concept. READ MORE
