  2. 21. Digital Distance Education – A Longitudinal Exploration of Video Technology

    Author : Lena Dafgård; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; distance education; digitalisation; video; higher education;

    Abstract : The context of this thesis is digital distance education. Distance education has developed from correspondence courses, based on letters sent by mail between student and teacher, to digital distance education with interactive video classes from anywhere, as long as a computer/tablet/smartphone and an Internet connection are available.

  4. 22. Distance Functions and Their Use in Adaptive Mathematical Morphology

    Author : Vladimir Ćurić; Gunilla Borgefors; Cris L. Luengo Hendriks; Hugues Talbot; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Image analysis; Distance functions; Mathematical morphology; Adaptive mathematical morphology; Image regularization; Computerized Image Processing; Datoriserad bildbehandling;

    Abstract : One of the main problems in image analysis is a comparison of different shapes in images. It is often desirable to determine the extent to which one shape differs from another. This is usually a difficult task because shapes vary in size, length, contrast, texture, orientation, etc. Shapes can be described using sets of points, crisp of fuzzy. READ MORE

  5. 23. Essays on Distance Based (Non-Euclidean) Tests for Spatial Clustering in Inhomogeneous Populations : Adjusting for the Inhomogeneity through the Distance Used

    Author : Ulla Romild; Johan Lyhagen; Anders Ågren; Jack Cuzick; Uppsala universitet; []
    Keywords : Statistics; Clustering; Spatial Point Pattern; Inhomogeneous Density; Statistik;

    Abstract : This thesis consits of four papers dealing with distance based (non-Euclidean) tests for spatial clustering in inhomogeneous populations. The density adjusted distance (DAD), which considers the underlying density, is defined in the first paper. READ MORE

  6. 24. Assessment of active commuting behaviour : walking and bicycling in Greater Stockholm

    Author : Erik Stigell; Peter Schantz; Andreas Nilsson; Maria Hagströmer; Gymnastik- och idrottshögskolan; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; walking; cycling; commuting; validity; reproducibility; distance; duration; velocity; frequency; seasonality; Sports; Idrott; Samhällsvetenskap Humaniora; Social Sciences Humanities; Sports Science;

    Abstract : Walking and bicycling to work, active commuting, can contribute to sustainable mobility and provide regular health-enhancing physical activity for individuals. Our knowledge of active commuting behaviours in general and in different mode and gender groups in particular is limited. READ MORE

  7. 25. Tales of Tailbiting Codes

    Author : Marc Handlery; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; maximum-likelihood decoding algorithm; minimum distance; active distance; woven convolutional code; tailbiting termination method; convolutional code; tailbiting code; Informatics; systems theory; Informatik; systemteori;

    Abstract : Tailbiting codes are error correcting codes and can be used in digital transmission systems. They are obtained by terminating convolutional codes into block codes. This thesis consists of an introduction to convolutional and tailbiting codes, and the Papers A--G that include the main results. READ MORE
