  2. 1. Modeling and Analysis of the Interaction of Batteries and Power Electronic Converters

    Author : Rúdi Soares; Oskar Wallmark; Remus Teodorescu; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Alternating current; aging; electric vehicles; harmonics; lithium-ion batteries; power converter; resonant filters; ripple; temperature control.; Electrical Engineering; Elektro- och systemteknik;

    Abstract : This thesis deals with the interaction of batteries and power electronic converters in automotive applications. Even if the additional heating caused by (unwanted) alternating currents is disregarded, there has been a concern that alternating currents can be harmful for batteries. READ MORE

  4. 2. Joint Attention in Development : Insights from Children with Autism and Infant Siblings

    Author : Emilia Thorup; Terje Falck-Ytter; Gustaf Gredebäck; Peter Mundy; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Autism Spectrum Disorder; Joint Attention; Gaze following; Alternating gaze; Social cognition; Eye tracking; Infant siblings; Psychology; Psykologi;

    Abstract : Compared to other children, children with Autism Spectrum Disorder (ASD) are known to engage less in joint attention - the sharing of attention between two individuals toward a common object or event. Joint attention behaviors - for example gaze following, alternating gaze, and pointing - play an important role in early development, as they provide a foundation for learning and social interaction.

  5. 3. Alternating Coding and its Decoder Architectures for Unary-Prefixed Codes

    Author : Shang Xue; Bengt Oelmann; Jukka Teuhola; Mittuniversitetet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electronics; Elektronik;

    Abstract : The entropy coding of high peak, heavy-tailed probability distributions such as the Laplacian, Cauchy, and generalized Gaussian have been a topic of interest because they are able to provide good models for data in many coding systems, especially in image and video coding systems. This thesis studies the entropy coding of such high peak, heavy-tailed probability distributions. READ MORE

  6. 4. An alternating iterative procedure for the Cauchy problem for the Helmholtz equation

    Author : Lydie Mpinganzima; Vladimir Kozlov; Bengt-Ove Turesson; Fredrik Berntsson; Börje Nilsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Let  be a bounded domain in Rn with a Lipschitz boundary Г divided into two parts Г0 and Г1 which do not intersect one another and have a common Lipschitz boundary. We consider the following Cauchy problem for the Helmholtz equation:where k, the wave number, is a positive real constant, аv denotes the outward normal derivative, and f and g are specified Cauchy data on Г0.

  7. 5. Biological effects of alternating magnetic fields with special reference to the visual system

    Author : Per Lövsund; Linköpings universitet; []
    Keywords : MEDICINE; MEDICIN;

    Abstract : The aims of the present investigation were to contribute to more knowledge of the interaction between extremely low frequency magnetic fields and excitable tissue and to widen the basic understanding of the mechanisms behind these effects. The human visual system and the frog retina were used as model systems. READ MORE
