  1. 1. Model Adaptivity in Elasticity

    Detta är en avhandling från Göteborg : Chalmers University of Technology

    Författare :David Heintz; Göteborgs universitet.; Gothenburg University.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; finite element method; dimension reduction; a posteriori error; model error; model adaptivity;

    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

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Ahsan Qamar; KTH.; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Mechatronics; mechatronic design; development process; conceptual design; model-based systems engineering MBSE ; model integration; SysML; model-driven engineering; consistency; TECHNOLOGY Industrial engineering and economy; TEKNIKVETENSKAP Industriell teknik och ekonomi; TECHNOLOGY Information technology Computer science Software engineering; TEKNIKVETENSKAP Informationsteknik Datavetenskap Programvaruteknik; TECHNOLOGY Information technology Systems engineering; TEKNIKVETENSKAP Informationsteknik 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

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Magnus Berglund; Linköpings universitet.; Linköpings universitet.; [1997]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; 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

    Detta är en avhandling från Stockholm : Department of Education, Stockholm University

    Författare :Åsa Larsson; Stockholms universitet.; [2013]
    Nyckelord :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

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Sören Wilhelms; Linköpings universitet.; Linköpings universitet.; [2003]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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.
