  1. 11. Målgruppen och budskapet : En modell för målgruppsanpassning av trafiksäkerhetsbudskap till unga manliga trafikanter

    Författare :Inger Linderholm; Medie- och kommunikationsvetenskap; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; young road-users; persuasion; planned communication; public information campaigns; attitude change; young drivers attitude scale; audience segmentation; message content; perceived risk; traffic safety; Press and communication sciences; media; Journalistik; media; kommunikation;

    Sammanfattning : The empirical work rests on two separate theoretical foundations: theories that form the basis for analyzing the different target groups and theories dealing with persuasion. Theories of the first sort concern life-style, individual values, perceived risk, individual characteristics and self-image. LÄS MER

  3. 12. Improving Multi-Atlas Segmentation Methods for Medical Images

    Författare :Jennifer Alvén; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Supervised learning; semantic segmentation; multi-atlas segmentation; conditional random fields; label fusion; feature-based registration; image registration; random decision forests; convolutional neural networks; medical image segmentation;

    Sammanfattning : Semantic segmentation of organs or tissues, i.e. delineating anatomically or physiologically meaningful boundaries, is an essential task in medical image analysis. One particular class of automatic segmentation algorithms has proved to excel at a diverse set of medical applications, namely multi-atlas segmentation. LÄS MER

  4. 13. Voltage Transients in the Field Winding of Salient Pole Wound Synchronous Machines : Implications from fast switching power electronics

    Författare :Roberto Felicetti; Urban Lundin; Jon Kjellin; Uppsala universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; apparent resistance; cable modeling; current control; transmission line model; eddy currents; field winding; frequency analysis response; Fourier Transform; impedance mismatch; main inductance; overvoltage; parasitic capacitance; partial discharge; quality factor; ringing; slew rate; stray inductance; voltage gradient; winding resonance frequency;

    Sammanfattning : Wound Field Synchronous Generators provide more than 95% of the electricity need worldwide. Their primacy in electricity production is due to ease of voltage regulation, performed by simply adjusting the direct current intensity in their rotor winding. LÄS MER

  5. 14. New Insights on Computerized Trading : Implications of Frequently Revised Trading Decisions

    Författare :Petter Dahlström; Björn Hagströmer; Lars Nordén; Andriy Shkilko; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Business Administration; företagsekonomi;

    Sammanfattning : Computerized trading may be viewed as an aspect of modernization of financial markets. This dissertation contains four articles that in different ways examine to what extent the modernization influences the economics of the markets. LÄS MER

  7. 15. Predictive Modelling to Support Design and Manufacturing in Aerospace Engineering

    Författare :Siva Krishna Dasari; Abbas Cheddad; Lars Lundberg; Stan Matwin; Blekinge Tekniska Högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; surrogate modelling; defects classification; machine learning; aerospace; additive manufacturing; Computer Science; Datavetenskap;

    Sammanfattning : A crucial issue in the design of aircraft components is the evaluation of a large number of potential design alternatives.  This evaluation involves too expensive procedures, consequently, it slows down the search for optimal design samples. LÄS MER
