  1. 1. Control Synthesis for Batch Processes

    Författare :Michael Tittus; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; batch control; hybrid systems; modeling; control synthesis; supervisory control; object-orientation; resource allocation;

    Sammanfattning : Batch applications form an important application class within the field of process industries. In this thesis we propose multiple models, frameworks and design concepts in order to apply formal methods to the control synthesis in batch control. The thes is can be divided into two main parts.

  4. 3. Approximation of Infinitely Divisible Random Variables with Application to the Simulation of Stochastic Processes

    Författare :Magnus Wiktorsson; Matematisk statistik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; operations research; Statistics; aktuariematematik; Stochastic differential equation; Infinitely divisible distribution; Type G distribution; Lévy process; Stochastic integral; Mathematical Statistics; Matematik; Mathematics; programming; actuarial mathematics; Statistik; operationsanalys; programmering;

    Sammanfattning : This thesis consists of four papers A, B, C and D. Paper A and B treats the simulation of stochastic differential equations (SDEs). The research presented therein was triggered by the fact that there were not any efficient implementations of the higher order methods for simulating SDEs. LÄS MER

  5. 4. Alliances for innovation : a structural perspective on new business development in cooperative ventures

    Författare :Håkan Linnarsson; Handelshögskolan i Stockholm; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Sammanfattning : The innovation race, with ever-shortening product lifecycles and esca-lating innovation costs, has made alliances for innovation a central competitive strategy at many firms. Alliances provide access to a broader pool of knowledge that would be difficult to develop inside the firm, as well as a way of sharing risks. LÄS MER

  7. 5. Geometric discretization for incompressible magnetohydrodynamics on the sphere

    Författare :Michael Roop; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Lie-Poisson structure; magnetohydrodynamics; Hamiltonian dynamics; magnetic extension; Casimirs; symplectic Runge-Kutta integrators;

    Sammanfattning : Many physical processes are modelled by partial differential equations (PDE), and their efficient discretization is still a challenging problem and an actively developing field. An important class of models arising in mathematical physics represents PDEs formulated in terms of a Lie-Poisson structure on the dual of infinite-dimensional Lie algebras, such as the Lie algebra of vector fields.
