    Sammanfattning : ABSTRACT Sandberg, Mattias, 2012, ’They are not outdoors that much’. Nature close to home – its meaning and place in the everyday lives of urban children. Publications edited by the Departments of Geography, University of Gothenburg, Series B, no. 122. LÄS MER

  3. 2. Approximation of Optimally Controlled Ordinary and Partial Differential Equations

    Författare :Mattias Sandberg; Anders Szepessy; Nils-Henrik Risebro; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; MATHEMATICS; MATEMATIK;

    Sammanfattning : In this thesis, which consists of four papers, approximation of optimal control problems is studied. In Paper I the Symplectic Pontryagin method for approximation of optimally controlled ordinary differential equations is presented. LÄS MER

  5. 4. Accuracy, efficiency and robustness for rigid particle simulations in Stokes flow

    Författare :Anna Broms; Anna-Karin Tornberg; Mattias Sandberg; Eric Keaveny; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Stokes flow; rigid particles; accuracy; fundamental solutions; method of images; multiblob; contact avoiding; complementarity problem; barrier method; elliptic PDE; grid optimisation; pair-correction; boundary integral equations; Stokesflöde; noggrannhet; stela partiklar; fundamentallösningar; randintegralekvation; reflektionspunkter; multiblob; kontaktundvikande algoritmer; komplementaritetsproblem; barriärmetod; elliptisk PDE; gridoptimering; parkorrektion; Numerical Analysis; Numerisk analys;

    Sammanfattning : The thesis concerns simulation techniques for systems of nano- to micro-scaled rigid particles immersed in a viscous fluid, ubiquitous in nature and industry. With negligible fluid inertia, the set of PDEs known as the Stokes equations can be used to model the hydrodynamics. LÄS MER

  7. 5. Managing variation in hospital patient flows

    Författare :Olle Olsson; Erik Sandberg; Mattias Elg; Daniel Ekwall; Linköpings universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES;

    Sammanfattning : Performing healthcare services is a complex practice. With the continuous developments in the medical field, healthcare organisations and professionals have become increasingly specialised, and healthcare services increasingly fragmented. LÄS MER
