  1. 1. Learning to be at a distance : structural and educational change in the digitalization of medical education

    Author : Fanny Pettersson; Anders D. Olofsson; Tor Söderström; Christina Ljungberg; Andreas Lund; Umeå universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Distance education; medical education; medical program; regionalized medical program; rural clinical school; digitalization; digital technologies; technology-enhanced learning; TEL; cultural-historical activity theory; CHAT; transition; transformation; conflicts; contradictions; dominant- non-dominant activities; levels of learning; pedagogik; Education;

    Abstract : As an expression of current challenges faced by contemporary societies, past decades have witnessed heavy demands for higher education to change and transform. One key question here has been the increased digitalization of higher education. READ MORE

  2. 2. Distance Protection of Transmission Lines with High Levels of Series Compensation : A study on frequency and time domain communication independent distance protection for series compensated lines

    Author : Md Tanbhir Hoq; Nathaniel Taylor; Jianping Wang; Claus Leth Bak; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Series capacitor; Series compensation; Transmission line; Distance protection; Incremental quantity; Lissajous curve; RL model; RLC model; Seriekondensator; Seriekompensation; Transmissionslinje; Distansskydd; Inkrementell kvantitet; Lissajous-kurva; RL-modell; RLC-modell; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Series capacitors are used in electric transmission lines to increase their power transfer capacity. They compensate for the inductive reactance of the line. They offer a useful alternative to building new lines, in view of economic and environmental constraints. READ MORE

  4. 4. Methods for Reliable Image Registration : Algorithms, Distance Measures, and Representations

    Author : Johan Öfverstedt; Natasa Sladoje; Mattias Heinrich; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Image registration; alignment; local optimization; global optimization; mutual information; normalized gradient fields; representation learning; Computerized Image Processing; Datoriserad bildbehandling;

    Abstract : Much biomedical and medical research relies on the collection of ever-larger amounts of image data (both 2D images and 3D volumes, as well as time-series) and increasingly from multiple sources. Image registration, the process of finding correspondences between images based on the affinity of features of interest, is often required as a vital step towards the final analysis, which may consist of a comparison of images, measurement of movement, or fusion of complementary information.

  5. 5. Image processing on optimal volume sampling lattices : Thinking outside the box

    Author : Elisabeth Schold Linnér; Robin Strand; Ewert Bengtsson; Alexandre Falcão; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BCC; FCC; aliasing; distance transform; segmentation; Computerized Image Processing; Datoriserad bildbehandling;

    Abstract : This thesis summarizes a series of studies of how image quality is affected by the choice of sampling pattern in 3D. Our comparison includes the Cartesian cubic (CC) lattice, the body-centered cubic (BCC) lattice, and the face-centered cubic (FCC) lattice. READ MORE
