  1. 1. Computational Methods for Hybrid Systems

    Författare :Sven Hedlund; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis considers two different computational approaches for the analysis and synthesis of nonlinear systems. Each of these approaches is presented in a conference paper that describes parts of the theory and algorithms. Matlab commands implementing the algorithms have been developed and the manuals for these are included herein as well.. LÄS MER

  3. 2. Computational Methods for Optimal Control of Hybrid Systems

    Författare :Sven Hedlund; Institutionen för reglerteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; reglerteknik; Automation; robotics; control engineering; robotteknik; Automatiska system;

    Sammanfattning : This thesis aims to find algorithms for optimal control of hybrid systems and explore them in sufficient detail to be able to implement the ideas in computational tools. By hybrid systems is meant systems with interacting continuous and discrete dynamics. Code for computations has been developed in parallel to the theory. LÄS MER

  4. 3. Climate change effects on migratory birds and on the ecology and behaviour of the willow warbler (Phylloscopus trochilus)

    Författare :Johanna Hedlund; Sven Jakobsson; Thord Fransson; Cecilia Kullberg; Sara Cousins; Martin Schaefer; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; climate change; bird migration; ecology; phenology; bird; avian; willow warbler; chaffinch; land use change; landscape ecology; historical ecology; etologi; Ethology;

    Sammanfattning : Recent global climate change is influencing the behaviour and ecology of species worldwide. Birds are typical systems to study in this context, as they are often migratory and thus subjected to a variety of environmental effects. LÄS MER
