  2. 1. A time and place for everything? : social visualisation tools and critical literacies

    Author : Veronica Johansson; Högskolan i Borås; []
    Keywords : SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Critical literacy; Document perspective; enactments of meaning; geographic information systems GIS ; ICT; information activities; inscriptions; interaction; library and information science LIS ; representation; social data; social visualisation tools; sociocultural perspective; Library and information science; Library and Information Science; Biblioteks- och informationsvetenskap;

    Abstract : The aim of this study is to analyse mutual enactments of critical literacies and social visualisation tools as information resources. The central concept of critical literacies as used here extends and redefines prior critical literacy definitions to denote the pluralistic situated enactments of meaning through which study participants identify, question and transform bias, restrictions and power related aspects of access, control and use in relation to the tools.

    Abstract : 3D city models have been widely used in different applications such as urban planning, traffic control, disaster management etc. Effective visualisation of 3D city models in various scales is one of the pivotal techniques to implement these applications. READ MORE

  6. 4. Graphic Representation and Visualisation as Modelling Support for the Knowledge Acquisition Process

    Author : Anne Håkansson; Andreas Hamfelt; Harald Kjellin; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; Artficial Intelligence; Knowledge-Based Systems; Knowledge Acquisition; Graphic Representation; Visualisation; Unified Modelling Language; Modelling Rule-based Systems; Visual programming; Declarative Programming; Information Networks; User-Centered Design; Knowledge Interface; Datavetenskap; Computer science; Datavetenskap; datalogi; Computer Science;

    Abstract : The thesis describes steps taken towards using graphic representation and visual modelling support for the knowledge acquisition process in knowledge-based systems – a process commonly regarded as difficult. The performance of the systems depends on the quality of the embedded knowledge, which makes the knowledge acquisition phase particularly significant. READ MORE

  7. 5. Segmentation and Visualisation of Human Brain Structures

    Author : Roger Hult; Ewert Bengtsson; Lennart Thurfjell; Håkan Hall; Ingrid Agartz; Arvid Lundervold; Uppsala universitet; []
    Keywords : NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Bildanalys; segmentation; visualisation; brain; cortex; hippocampus; autoradiography; MRI; PET; ROI; Bildanalys; Image analysis; Bildanalys; Computerized Image Analysis; datoriserad bildanalys;

    Abstract : In this thesis the focus is mainly on the development of segmentation techniques for human brain structures and of the visualisation of such structures. The images of the brain are both anatomical images (magnet resonance imaging (MRI) and autoradigraphy) and functional images that show blood flow (functional magnetic imaging (fMRI), positron emission tomography (PET), and single photon emission tomograpy (SPECT)).
