  1. 1. Model Adaptivity in Elasticity

    Författare :David Heintz; Göteborgs universitet; Göteborgs universitet; Gothenburg University; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; finite element method; dimension reduction; a posteriori error; model error; model adaptivity; model error;

    Sammanfattning : We consider model adaptivity in elasticity for dimensionally reduced forms, and shall treat different conceptual approaches. The basic idea, however, is to adaptively refine, not only the computational mesh, but also the underlying mathematical formulation. LÄS MER

  2. 2. An Integrated Approach towards Model-Based Mechatronic Design

    Författare :Ahsan Qamar; Jan Wikander; Hans Vangheluwe; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; Mechatronics; mechatronic design; development process; conceptual design; model-based systems engineering MBSE ; model integration; SysML; model-driven engineering; consistency; Industrial engineering and economy; Industriell teknik och ekonomi; Software engineering; Programvaruteknik; Systems engineering; Systemteknik;

    Sammanfattning : Mechatronic design is an enigma. On the one hand, mechatronic products promise enhanced functionality, and better performance at reduced cost. On the other hand, optimizing mechatronic design concepts is a major challenge to overcome during the design process. LÄS MER

  3. 3. Third-party logistics providers : towards a conceptual strategic model

    Författare :Magnus Berglund; Statens väg- och transportforskningsinstitut; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Third-party logistics; Third-party logistics providers; Strategy; Positioning; Subcontracting; Outsourcing; Future; Supply chain integration;

    Sammanfattning : The purpose of the study is to: 1. develop a model for studying the strategies of third-party providers, and 2. preparing empirically supported hypotheses regarding the TPL providers strategies. LÄS MER

  4. 4. A structural view on conceptual change : Integration, differentiation, and contextualization as fundamental aspects of individual meaning making

    Författare :Åsa Larsson; Jon Ohlsson; Erno Lehtinen; Stockholms universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; conceptual development; conceptual change; coherence; contextualization; pedagogik; Education;

    Sammanfattning : Conceptual development and conceptual change processes are described by a longitudinal study on preschool children’s conception of the earth. Conceptual change is often described as a causal process in which changes in an embraced system of beliefs result in a new system of beliefs. LÄS MER

  5. 5. Reuse of principle solution elements in conceptual design : an information model for concepts in systematic design

    Författare :Sören Wilhelms; Linköpings universitet; []
    Nyckelord :conceptual design; functional modelling; constraint-based design; design reuse; VDI 2222; product modelling; design support; TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Product development is an important activity in engineering design, and much of the competitiveness in high-salary countries depends on the ability to develop innovative products with acceptable time to market.The early phase of a systematic design process, namely conceptual design, during which the principle solution for a product is conceived, is of high importance for the later success of products.
