  1. 21. Duality-based adaptive finite element methods with application to time-dependent problems

    Författare :August Johansson; Mats G. Larson; Paul Houston; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; finite element methods; dual-weighted residual method; multiphysics; a posteriori error estimation; adaptive algorithms; discontinuous Galerkin; MATHEMATICS; MATEMATIK; Mathematics; matematik;

    Sammanfattning : To simulate real world problems modeled by differential equations, it is often not sufficient to  consider and tackle a single equation. Rather, complex phenomena are modeled by several partial dierential equations that are coupled to each other. LÄS MER

  3. 22. Numerical simulation of tube hydroforming : adaptive loading paths

    Författare :Joakim Lundqvist; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Structural Engineering; Konstruktionsteknik;

    Sammanfattning : The tube hydroforming process is still to be considered a new and advanced technique. The process has been adopted into several industries, e.g. automotive and aero. LÄS MER

  5. 24. Assessment of Application of Participatory Methods for Complex Adaptive Systems  in the Public Sector

    Författare :Maksims Kornevs; Sebastiaan Meijer; Jannicke Baalsrud Hauge; Paul Grogan; KTH; []
    Nyckelord :: participatory methods; complex adaptive system; public sector; change process; assessment; participativa metoder; komplext adaptivt system; offentlig sektor; förändringsprocess; bedömning;

    Sammanfattning : The provision of services by the public sector is the result of a complex adaptive system at work, and involves a large number of stakeholders from different institutions and organisations. In the era of rapid change in requirements and expectations from the public sector, the management of change processes asks for the involvement of many stakeholders from different layers and positions.

  7. 25. Efficient Electromagnetic Induction Modelling : Adaptive mesh optimisation, advanced boundary methods and iterative solution techniques

    Författare :Laura M. Buntin; Thomas Kalscheuer; Gunilla Kreiss; Zhengyong Ren; Klaus Spitzer; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Applied geophysics; Electromagnetic theory; Numerical Modelling; Geo-Electromagnetics; Magnetotellurics; Controlled-source electromagnetics; Goal-oriented adaptive mesh refinement; Perfectly-matched layers; Iterative solution methods; Preconditioning; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Sammanfattning : Forward modelling of electromagnetic induction data simulates the electric and magnetic fields within a computational domain for a given distribution of electromagnetic material properties and a given source of the electromagnetic field. The quantities of interest are the fields at receiver locations at the Earth's surface. LÄS MER
