  2. 11. Creating multimodal texts in language education

    Author : Anna-Lena Godhe; Göteborgs universitet; []
    Keywords : HUMANIORA; HUMANITIES; collaborative writing; ICT; positioning; framing; interaction analysis; activity theory; boundary objects;

    Abstract : I denna licentiatuppsats undersöks gymnasieelevers skapande av digitala berättelser i svenska eller svenska som andraspråk i en skolpraktik. Analysen grundas på videoupptagningar av par eller mindre grupper under deras arbete med sina multimodala texter. I uppsatsen presenteras två par studenter och deras interaktion i två fallstudier.

  4. 12. Prototyping for Product-Service Systems innovation : Insights from the construction equipment industry

    Author : Ryan Ruvald; Andreas Associate Professor (Docent); Åsa Ericsson; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Product-Service System; Engineering Design; Prototyping; Boundary Objects;

    Abstract : To radically increase the value delivered to the customers in the construction industry a concerted effort is needed to develop solutions beyond incremental adjustments. Simply providing add-on services to existing products does not effectively create solutions with enough gains in core customer values. READ MORE

  5. 13. Boundary Detection in Cardiovascular Ultrasonic Images Based on Multiscale Dynamic Programming

    Author : Quan Liang; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; multiscale dynamic programming; artery measurement; cardiac measurement; edge-preserving smoothing; ultrasonic imaging; boundary detection;

    Abstract : Non-invasive ultrasonic imaging is widely used in cardiovascular studies as well as clinical diagnostics. This is due to its non-invasiveness, low cost and easy operation. However, ultrasonic images are noisy and present artifacts, speckles, and echo dropouts. READ MORE

  6. 14. Enabling boundary-crossing collaboration for innovation : issues for collaborative working environments

    Author : Marita Holst; Luleå tekniska universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Informatik; Informatics;

    Abstract : In this thesis, boundary-crossing collaborative knowledge work aiming for innovation and use of ICT is in focus. The starting point for the research was the proposition that we still have much to learn about boundary- crossing collaboration for innovation and the use of ICT before we can design enabling and supporting ICT and collaborative working environments.

  7. 15. Strings, boundary fermions and coincident D-branes

    Author : Linus Wulff; Ulf Lindström; Fawad Hassan; Dmitri Sorokin; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; string theory; open strings; D-branes; supersymmetry; non-abelian gauge theory; tensionless strings; Physics; Fysik;

    Abstract : The appearance in string theory of higher-dimensional objects known as D-branes has been a source of much of the interesting developements in the subject during the past ten years. A very interesting phenomenon occurs when several of these D-branes are made to coincide: The abelian gauge theory living on each brane is enhanced to a non-abelian gauge theory living on the stack of coincident branes.
