  2. 21. Multiscale X-ray Characterisation of Cellulose-based Solid Dispersions

    Author : Martina Olsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; PXCT; WAXS; pharmaceutical formulations; multiscale characterisation; STXM; radiation damage; SAXS; X-ray imaging; solid dispersions; cellulose;

    Abstract : Cellulose-based solid dispersions are a promising formulation strategy for providing controlled drug release and dissolution enhancement of poorly soluble drugs. These dispersions can from structures on multiple length scales which can have both positive and negative effects on the functional properties of the formulation. READ MORE

  4. 22. Finite element methods for multiscale/multiphysics problems

    Author : Robert Söderlund; Mats Larson; Victor Ginting; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; finite element methods; variational multiscale methods; Galerkin; convergence analysis; multiphysics; a posteriori error estimation; duality; adaptivity; Mathematical statistics; Matematisk statistik; Mathematical Statistics; matematisk statistik;

    Abstract : In this thesis we focus on multiscale and multiphysics problems. We derive a posteriori error estimates for a one way coupled multiphysics problem, using the dual weighted residual method. READ MORE

  5. 23. On discontinuous Galerkin multiscale methods

    Author : Daniel Elfverson; Axel Målqvist; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Beräkningsvetenskap med inriktning mot numerisk analys; Scientific Computing with specialization in Numerical Analysis;

    Abstract : In this thesis a new multiscale method, the discontinuous Galerkin multiscale method, is proposed. The method uses localized fine scale computations to correct a global coarse scale equation and thereby takes the fine scale features into account. READ MORE

  6. 24. Method development for co-simulation of electrical-chemical systems in Neuroscience

    Author : Ekaterina Brocke; Jeanette Hellgren Kotaleski; Gaute Einevoll; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; multiscale; multirate; co-simulation; electrical-chemical; Computer Science; Datalogi;

    Abstract : Multiscale modeling and simulation is a powerful approach for studying such phenomena in nature as learning and memory. In computational neuroscience, historically, methods and tools for neuronal modeling and simulations have been developed for studies focused on a single level of the neuronal organization. READ MORE

  7. 25. Multiscale Modeling in Systems Biology : Methods and Perspectives

    Author : Adrien Coulier; Andreas Hellander; Mark Chaplain; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; computational systems biology; high performance computing; Bayesian inference; stochastic simulation; cell mechanics; Scientific Computing; Beräkningsvetenskap;

    Abstract : In the last decades, mathematical and computational models have become ubiquitous to the field of systems biology. Specifically, the multiscale nature of biological processes makes the design and simulation of such models challenging. READ MORE
