  3. 2. Samskapande datortillämpningar : en systemteoretisk ansats för lösning av vissa förändringsproblem vid administrativ datoranvändning

    Författare :Olov Forsgren; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Constructive; co-constructive; humanistic; design; computer application; change problem; information system; client orientation; implementation;

    Sammanfattning : This thesis starts by observing a change problem in a medical computer application. The change problem occurs when data and rules that make up the core of a computer application, degenerate. Sometimes the process is slow, but it is not unusual for the application to be out of date even before it has been put into use. LÄS MER

  4. 3. Information Integration in Computer Aided Design

    Författare :Erik Lejon; Lars-Erik Lindgren; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Datorstödd maskinkonstruktion; Computer Aided Design;

    Sammanfattning : Information management during product development and over the lifecycle of products has become central to enable competitiveness in the engineering industry. Reuse and integration of information is essential to avoid duplicating efforts. LÄS MER

  5. 4. A first sketch of Computer Aided Ideation : Exploring CAD tools as externalization media in design ideation

    Författare :Philip Ekströmer; Renee Wever; Johan Ölvander; Peter Törlind; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Even though Computer Aided Design (CAD) tools have changed the way designers work in most parts of the design process, designers still mostly use pen-and-paper sketching when generating design ideas. Previous studies exploring the use of CAD tools for design ideation have concluded that the tools available at the time did not support reflective conversation, serendipitous interpretation and creativity, making them unsuited for design ideation.

  7. 5. Computer Aided Angioplasty : Patient-specific arterial modeling and smooth 3D contact analysis of the stent-balloon-artery interaction

    Författare :Dimitrios Kiousis; Gerhard Holzapfel; Kenneth Runesson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Contact; continuous surfaces; B-splines; balloon angioplasty; stenting; FEM; Bioengineering; Bioteknik;

    Sammanfattning : Paper A: In this paper, the development and implementation of a contact algorithm based on C2-continuous surface representations is discussed. In 3D contact simulations involving models with arbitrarily curved surfaces (as in the case of vessel walls), the discretization of the contact surfaces by means of facet-based techniques could lead to numerical instabilities and finally loss of quadratic convergence.
