1. 11. On identification of endocrine systems

   Författare :Egi Hidayat; Alexander Medvedev; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

   Sammanfattning : System identification finds nowadays application in various areas of biomedical research as a tool of empiric mathematical modeling and model individualization. Hormone regulation is a classical example of biological feedback where control theories, in general, and system identification, in particular, are indispensable in unraveling the regulation mechanisms and explicating the complex dynamical phenomena arising in endocrine systems.

3. 12. Capturing and Analysing Emotions to Support Organisational Learning : The Affect Based Learning Matrix

   Författare :Theresia Olsson Neve; Paul Johannesson; Janis Stirna; Marite Kirikova; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Knowledge Management; Organisational Learning; Emotions; Affects; Perspective Change; Knowledge Management Systems; Web-based Knowledge Management Support; Computer and systems science; Data- och systemvetenskap;

   Sammanfattning : This thesis deals with the importance of managing employees’ thoughts and feelings in relation to organisational learning. To visualise and to identify affections within organisations is of major importance since most of our actions and the decisions we make are steered by our emotions rather than rational thinking.

4. 13. Initialization Methods for System Identification

   Författare :Christian Lyzell; Lennart Ljung; Martin Enqvist; Magnus Jansson; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System identification; Initialization methods; Regressor selection; Identifiability; Automatic control; Reglerteknik;

   Sammanfattning : In the system identification community a popular framework for the problem of estimating a parametrized model structure given a sequence of input and output pairs is given by the prediction-error method. This method tries to find the parameters which maximize the prediction capability of the corresponding model via the minimization of some chosen cost function that depends on the prediction error.

5. 14. Estimation of Nonlinear Dynamic Systems : Theory and Applications

   Författare :Thomas B. Schön; Fredrik Gustafsson; Simon Godsill; Linköpings universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Nonlinear estimation; system identification; Kalman filter; particle filter; marginalized particle filter; expectation maximization; automotive applications; Automatic control; Reglerteknik;

   Sammanfattning : This thesis deals with estimation of states and parameters in nonlinear and non-Gaussian dynamic systems. Sequential Monte Carlo methods are mainly used to this end. These methods rely on models of the underlying system, motivating some developments of the model concept. LÄS MER

7. 15. Modeling and Control of Bilinear Systems : Application to the Activated Sludge Process

   Författare :Mats Ekman; Bengt Carlsson; Claes Breitholtz; Uppsala universitet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bilinear systems; modeling; optimal control; parameter estimation; errors-in-variables; activated sludge process; Automatic control; Reglerteknik;

   Sammanfattning : This thesis concerns modeling and control of bilinear systems (BLS). BLS are linear but not jointly linear in state and control. In the first part of the thesis, a background to BLS and their applications to modeling and control is given. LÄS MER
