  1. 1. Fluid Mechanics of Vertical Axis Turbines : Simulations and Model Development

    Författare :Anders Goude; Olov Ågren; Carlos Simão Ferreira; Uppsala universitet; []
    Nyckelord :Wind power; Marine current power; Vertical axis turbine; Wind farm; Channel flow; Simulations; Vortex model; Streamtube model; Control system; Graphics processing unit; CUDA; Fast multipole method; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Sammanfattning : Two computationally fast fluid mechanical models for vertical axis turbines are the streamtube and the vortex model. The streamtube model is the fastest, allowing three-dimensional modeling of the turbine, but lacks a proper time-dependent description of the flow through the turbine. LÄS MER

  3. 2. Designing Platform Emulation

    Författare :Daniel Rudmark; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; open platforms; platform emulation; outlaw innovation; action design research; guided emergence; open platforms;

    Sammanfattning : Many contemporary firms and public agencies seek to engage external third-party developers to supply complementary applications. However, this type of development sometimes occurs without organizational consent, which creates problems for subjected organizations at both the technical and organizational levels. LÄS MER

  4. 3. Integration of Enterprise Modeling and Model Driven Development : A Meta-Model and a Tool Prototype

    Författare :Iyad Zikra; Janis Stirna; Jelena Zdravkovic; Anne Persson; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Model-Driven Development; MDD; Enterprise Modeling; EM; Meta-model; Prototype; Design Science; Tool Implementation; informationssystem; Information Systems;

    Sammanfattning : The use of models for designing and developing Information Systems (IS) has changed in recent years. Models are no longer considered a peripheral documentation medium that is poorly maintained and often neglected. LÄS MER

  5. 4. Efficient Means for Platform-Based Development – Emphasizing Integrated, Information-Rich System Models

    Författare :Stellan Gedell; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; function-means model; product families; product model; design rationale; integral model; platform-based design; reuse; systems theory; complete; consistent; product development; configurable component;

    Sammanfattning : Competition in the automotive industry is fierce, which in recent years has been demonstrated by some of the companies’ struggle to survive. A significant challenge is posed by the market’s ever-increasing expectations of new and impressive products, while maintaining profitability. LÄS MER

  7. 5. The Problem with Errors : Solution Search in Platform Development

    Författare :Ramsin Yakob; Fredrik Tell; Lars Lindkvist; Carliss Baldwin; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Platform; Problem-solving; Decomposability; Solution search; Problem; Error; Plattform; Problemlösning; Nedbrytbarhet; Lösningssökande; Problem; Fel; Business and economics; Ekonomi;

    Sammanfattning : This dissertation is concerned with problem-solving in platform development. A problem isconceived of as an obstacle that needs to be overcome in order to reach a desired outcome,whereas a solution is denoted by the set of activities required to reach such an outcome. LÄS MER
