  2. 1. Norm-Regulation of Agent Systems : Instrumentalizing an algebraic approach to agent system norms

    Author : Magnus Hjelmblom; Magnus Boman; Jan Odelstad; Kim Solin; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Agent System; Norm-regulated; Norm-governed; Normative MAS; Normative Positions; Normative system; Transition system; Computer and Systems Sciences; data- och systemvetenskap;

    Abstract : An architecture for norm-regulated multi-agent systems based on an algebraic approach to normative systems is instrumentalized and further developed. The core of the instrumentalization is a Prolog module, which together with a Java library can be used for creating client/server-based runtime systems. READ MORE

  4. 2. Robust inference of gene regulatory networks : System properties, variable selection, subnetworks, and design of experiments

    Author : Torbjörn E. M. Nordling; Elling W Jacobsen; Rolf Findeisen; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; network inference; reverse engineering; variable selection; model selection; feature selection; subset selection; system identification; system theory; network theory; subnetworks; design of experiments; perturbation experiments; gene regulatory networks; biological networks;

    Abstract : In this thesis, inference of biological networks from in vivo data generated by perturbation experiments is considered, i.e. deduction of causal interactions that exist among the observed variables. Knowledge of such regulatory influences is essential in biology. READ MORE

  5. 3. Versatile Implementations of an Improved Cell-Free System for Protein Biosynthesis : Functional and structural studies of ribosomal protein L11 and class II release factor RF3. Novel biotechnological approach for continuous protein biosynthesis

    Author : Lamine Bouakaz; Måns Ehrenberg; Richard Buckingham; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular biology; Protein synthesis; translation termination; ribosome; release factor; cell-free system; missense error; gel filtration; affinity chromatography; Molekylärbiologi; Molecular biology; Molekylärbiologi;

    Abstract : Advances in genetics, proteomics and chromatography techniques have enabled the successfully generation of a cell-free bacterial translation system composed of highly pure and active components. This system provided an ideal platform for better elucidating the mechanism of each individual step of the prokaryotic protein biosynthesis and the function of the translation factors involved in the process.

  6. 4. Structural Reformulations in System Identification

    Author : Christian Lyzell; Martin Enqvist; Lennart Ljung; Alessandro Chiuso; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; System identification; Dimension reduction; Subspace identification; Difference algebra;

    Abstract : In system identification, the choice of model structure is important and it is sometimes desirable to use a flexible model structure that is able to approximate a wide range of systems. One such model structure is the Wiener class of systems, that is, systems where the input enters a linear time-invariant subsystem followed by a time-invariant nonlinearity. READ MORE

  7. 5. Initialization Methods for System Identification

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

    Abstract : 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.
