  1. 11. Medieteknik i en senmodern tid. Digital teknik, estetik och gestaltning

    Författare :Peter Ekdahl; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; digital teknik; estetik; gestaltning;

    Sammanfattning : Avhandlingen tar sin utgångspunkt i utvecklingsarbetet med utbildningsprogrammet Medieteknik med inriktning mot interaktiva system på Blekinge tekniska högskola (BTH) åren 2000-2005. Etablerandet innebar en möjlighet att pröva former och innehåll för att utveckla en framtidsinriktad utbildning inom digital teknik. LÄS MER

  3. 12. On LFSR based Stream Ciphers - analysis and design

    Författare :Patrik Ekdahl; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; self-shrinking generator; shrinking generator; E0; A5; sober; stream cipher; LFSR; snow; Informatics; systems theory; Informatik; systemteori;

    Sammanfattning : Stream ciphers are cryptographic primitives used to ensure privacy in digital communication. In this thesis we focus on stream ciphers built using Linear Feedback Shift Registers (LFSRs). Several different stream ciphers are analysed and new attacks are presented. In addition, two new stream ciphers are presented, both based on the same design. LÄS MER

  4. 13. Teaching for the learning of additive part-whole relations : The power of variation and connections

    Författare :Anna-Lena Ekdahl; Ulla Runesson Kempe; Hamsa Venkat; Camilla Björklund; Christiane Benz; Jönköping University; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; variation; variation theory; connections in teaching; making connections; early numbers; teaching and learning additive relations; part-whole relation; part-whole relations of numbers; intervention study;

    Sammanfattning : In this thesis, results from four empirical studies and a re-analysis are synthesized with what can constitute a structural approach to teaching and learning additive part-whole relations among learners aged four to eight years. In line with a structural approach to additive relations, the relations of parts and whole are in focus from the outset and are seen as the basis for addition and subtraction (Davydov 1982; Neuman, 1987).

  7. 15. Infective Endocarditis : aspects of pathophysiology, epidemiology, management and prognosis

    Författare :Christer Ekdahl; Rolf Maller; Mats Broqvist; Urban Forsum; Lennart E. Nilsson; Rune Andersson; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; epidemiology; Infective endocarditis IE ; heart valve surgery; monocytes; granulocytes; staphylococ; Epidemiology; Epidemiologi;

    Sammanfattning : Infective endocarditis (IE) is a rare but complex disease that is fatal if untreated. With a modern combination of antimicrobial therapy and heart valve surgery, mortality is still 10-20 %. The structure of the endocarditis vegetation impedes the penetration of phagocytic cells such as monocytes and granulocytes. LÄS MER
