1. 21. Flexibel utbildning i gymnasieskolan : Utvidgade klassrum och minskad transaktionell distans

   Författare :Rolf Edström; Gunnar Grepperud; Uppsala universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Education; ICT; transactional distance; flexible education; autonomy; individualized instruction; upper secondary school; Pedagogik; Education; Pedagogik; pedagogik; Education;

   Sammanfattning : During the 1990s radical reforms were effected in the Swedish school, at the same time as computerizing and the use of Internet increased considerably. The thesis discusses the dynamics and uncertainty that arise when changes and new technique appear in school and shall be combined with already ongoing works of change. LÄS MER

3. 22. Distance Functions and Image Processing on Point-Lattices : with focus on the 3D face- and body-centered cubic grids

   Författare :Robin Strand; Gunilla Borgefors; Stina Svensson; Christer Kiselman; David Coeurjolly; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computerized image analysis; digital geometry; distance functions; non-standard grids; point-lattices; Image analysis; Bildanalys;

   Sammanfattning : There are many imaging techniques that generate three-dimensional volume images today. With higher precision in the image acquisition equipment, storing and processing these images require increasing amount of data processing capacity. Traditionally, three-dimensional images are represented by cubic (or cuboid) picture elements on a cubic grid. LÄS MER

4. 23. Digital Distance Education – A Longitudinal Exploration of Video Technology

   Författare :Lena Dafgård; Göteborgs universitet; []
   Nyckelord :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;

   Sammanfattning : 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.

5. 24. Distance Functions and Their Use in Adaptive Mathematical Morphology

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

   Sammanfattning : 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. LÄS MER

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

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

   Sammanfattning : 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. LÄS MER
