  2. 1. Adaptive Forgetting through Multiple Models and Adaptive Control of Car Dynamics

    Author : Peter Andersson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adaptive forgetting; Multiple models; Adaptive control; Car dynamics;

    Abstract : A new recursive identif ication method, Adaptive Forgetting through Multiple Models - AFMM, is presented and evaluated using computer simulations. AFMM is specif ically suited for identification of systems with jumping or rapidly changing parameters. READ MORE

  4. 2. Adaptive evolution in multidimensional trait spaces

    Author : Paula Vasconcelos; Claus Rüffler; Maria Servedio; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; adaptive dynamics; mutidimensional trait spaces; evolutionary dynamics; disruptive selection; resource competition; diversification;

    Abstract : Negative frequency-dependent disruptive selection, which arises due to the interplay between organisms of a population and their environment, is an important element driving phenotypic diversification and even speciation. Such selection regime can result from frequency- and density-dependent interactions between the organisms and their environment, so that the fitness landscape itself changes as the population evolves.

  5. 3. Adaptive Finite Element Methods for Optimal Control Problems

    Author : Karin Kraft; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; dual weighted residual; adaptive; Newton method; variational inequality; vehicle dynamics.; multilevel algorithm; discontinuous Galerkin method; a posteriori error estimate; finite element method; optimal control; control constraint;

    Abstract : In this thesis we study the numerical solution of optimal control problems. The problems considered consist of a systemof differential equations, the state equations, which are governed bya control variable. The goal is to determine the states and controls which minimize a given cost functional. READ MORE

  7. 5. Modelling the Structural Dynamics of Business Networks : Two Agent-based Models of Supply Networks

    Author : Sara Shahin Moghadam; Frans Prenkert; Franziska Klügl; Magnus Hansson; Davide Secchi; Örebro universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Business networks; dynamics; Agent-based modelling; structural change; responses; interactions; complex adaptive systems;

    Abstract : This thesis aims at describing and analysing the structural changes of business networks that emerge as a result of change triggers. Despite previous studies, our understanding of the evolution of the network structure and its influencing factors is still limited. READ MORE
