  1. 16. Design of High Performance Computing Software for Genericity and Variability

    Författare :Malin Ljungberg; Michael Thuné; Kurt Otto; Hans Petter Langtangen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; PDE solver; high-performance; coordinate invariant; curvilinear coordinates; symmetry exploiting; generalized Fourier transform; finite difference; expression templates; feature modeling; variability; Beräkningsvetenskap; Scientific Computing;

    Sammanfattning : Computer simulations have emerged as a cost efficient complement to laboratory experiments, as computers have become increasingly powerful. The aim of the present work is to explore the ideas of some state of the art software development practices, and ways in which these can be useful for developing high performance research codes.

  3. 17. Information Integration in Perception and Cognition : Exploring the Perception-Cognition Gap

    Författare :Elina Stengård; Ronald van den Berg; Adam Sanborn; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Perception; Cognition; Information integration; Judgment; Computational modeling; Bayesian inference; Psychology; Psykologi;

    Sammanfattning : Much research in both perceptual inference and cognitive inference has focused on how well human performance fares against what is considered the most optimal or rational thing to do. The verdict, however, differs between the fields. LÄS MER

  4. 18. Towards Effective and Efficient Business Model change : Opportunities and challenges for software-intensive product development companies

    Författare :Magnus Wilson; Krzysztof Wnuk; Kari Smolander; Blekinge Tekniska Högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; business modeling; business flexibility; Learning organization; digitalization; governance; value capture; value creation; knowledge creation; knowledge management;

    Sammanfattning : Digitalization initiates and drives significant changes to the process level, organization level, and business level of software-intensive product development (SIPD) companies and their customers. Digitalization creates new opportunities through digital transformation strategies of the business environment. LÄS MER

  5. 19. On Modeling and Diagnosis of Friction and Wear in Industrial Robots

    Författare :André Carvalho Bittencourt; Svante Gunnarsson; Mattias Nyberg; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Industrial robots are designed to endure several years of uninterrupted operation and therefore are very reliable. However, no amount of design effort can prevent deterioration over time, and equipments will eventually fail. Its impacts can, nevertheless, be considerably reduced if good maintenance/service practices are performed. LÄS MER

  7. 20. Development and Validation of a Numerical Tool for the Aeromechanical Design of Turbomachinery

    Författare :María Angélica Mayorca; Torsten Fransson; Damian Vogt; Eric Seinturier; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; aeromechanical design; turbomachinery; numerical tool; reduced order modeling; mistuning; ROM; aero-structure coupling; CFD; FEM; methods; Mechanical energy engineering; Mekanisk energiteknik;

    Sammanfattning : In aeromechanical design one of the major rules is to operate under High Cyclic Fatigue (HCF) margins and away from flutter. The level of dynamic excitations and risk of HCF can be estimated by performing forced response analyses from blade row interaction forces or Low Engine Order (LEO) excitation mechanisms. LÄS MER
