  1. 1. Automation of Computational Mathematical Modeling

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Anders Logg; Göteborgs universitet.; Gothenburg University.; [2004]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; computational mathematical modeling; automation; adaptivity; multi-adaptivity; individual time steps; dual problem; a priori; a posteriori; model reduction; individual time steps; a posteriori; automation; model reduction; dual problem; adaptivity; a priori; multi-adaptivity;

    Abstract : This thesis concerns the Automation of Computational Mathematical Modeling (CMM), involving the key steps of automation of (i) discretization, (ii) discrete solution, (iii) error control, (iv) modeling, and (v) optimization. The automation of (i)--(ii) is realized through multi-adaptive Galerkin methods on general discretizations of space-time with time steps variable in space. READ MORE

  2. 2. Adaptive Middleware for Self-Configurable Embedded Real-Time Systems Experiences from the DySCAS Project and Remaining Challenges

    University dissertation from Göteborg : Chalmers University of Technology

    Author : Magnus Persson; Martin Törngren; DeJiu Chen; Thiemo Voigt; []
    Keywords : adaptivity; embedded real-time systems; DySCAS; DyLite; quality of service QoS ; load balancing; resource constraints; model-based design; component-based design; software architecture; adaptive middleware;

    Abstract : Development of software for embedded real-time systems poses severalchallenges. Hard and soft constraints on timing, and usually considerableresource limitations, put important constraints on the development. Thetraditional way of coping with these issues is to produce a fully static design,i.e. READ MORE
