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

    University dissertation from Borås : University of Borås

    Author : Veronica Johansson; Högskolan i Borås.; [2012]
    Keywords : 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.

  4. 2. Visualisation and Generalisation of 3D City Models

    University dissertation from Stockholm : KTH

    Author : Bo Mao; KTH.; [2010]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; 3D city models; Visualisation; CityGML; X3D; Generalisation; Aggregation; Typification; Quality evaluation; TECHNOLOGY Information technology; TEKNIKVETENSKAP Informationsteknik; SRA - E-vetenskap SeRC ; SRA - E-Science SeRC ;

    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

  5. 3. Graphic Representation and Visualisation as Modelling Support for the Knowledge Acquisition Process

    University dissertation from Uppsala : Institutionen för informationsvetenskap

    Author : Anne Håkansson; Uppsala universitet.; [2003]
    Keywords : 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; TECHNOLOGY Information technology Computer science; TEKNIKVETENSKAP Informationsteknik 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

  6. 4. Segmentation and Visualisation of Human Brain Structures

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Roger Hult; Uppsala universitet.; [2003]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Bildanalys; segmentation; visualisation; brain; cortex; hippocampus; autoradiography; MRI; PET; ROI; Bildanalys; TECHNOLOGY Information technology Image analysis; TEKNIKVETENSKAP Informationsteknik 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)).

  7. 5. Temporality in the Interaction Design of Information Systems

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Anna Gryszkiewicz; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; temporality; Crisis management; information systems; interaction design; disaster management; human-computer interaction; time;

    Abstract : ABSTRACTThis thesis contributes with two tools that can be used by designers and researchers in exploring how to address time in the design of crisis response and management information systems. By crisis management information system is here meant information systems used by local and regional authorities when responding to events that may disturb important societal functions, such as: floods, storms, terror attacks, and spreading of infectious diseases.
