  4. 2. Multivariable Orthogonal Polynomials as Coupling Coefficients for Lie and Quantum Algebra Representations

    Author : Hjalmar Rosengren; Matematik (naturvetenskapliga fakulteten); []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; higher order Hankel form; Wigner symbol; quadratic algebra; Clebsch-Gordan coefficient; quantum group; Lie group; highest weight representation; multivariable orthogonal and biorthogonal polynomials; multivariable hypergeometric and basic hypergeometric functions; algebraisk topologi; Geometry; Geometri; algebraic topology;

    Abstract : The main topic of the thesis is the connection between representation theory and special functions. We study matrix elements, coupling coefficient, and recoupling coefficients for the simplest Lie and quantum groups. READ MORE

  5. 3. On Model Simplification in System Identification

    Author : Bo Wahlberg; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Model simplification; System identification;

    Abstract : This report deals with the connection between system identification and model reduction. We propose an identification algorithm that is based on the least squares identification method and either of the model reduction techniques: Frequency weighted truncated balanced realization or frequency weighted optimal Hankel-norm model reduction.

  6. 4. Applications of 3D time domain wave splittings to direct and inverse scattering

    Author : Jiasu Cao; KTH; []
    Keywords : ;

    Abstract : The three-dimensional direct and inverse scattering problems in the time-domain are considered in the present thesis. The direct problem is to find an explicit or numerical solution of the transient reflection for given physical parameters. READ MORE

  7. 5. Interaction Analysis in Multivariable Control Systems : Applications to Bioreactors for Nitrogen Removal

    Author : Björn Halvarsson; Bengt Carlsson; Elling Jacobsen; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; activated sludge process; biological nitrogen removal; bioreactor models; control structure design; cost-efficient operation; decentralized control; interaction measures; minimum variance control; multivariable control; wastewater treatment; Automatic control; Reglerteknik; Elektroteknik med inriktning mot reglerteknik; Electrical Engineering with specialization in Automatic Control;

    Abstract : Many control systems of practical importance are multivariable. In such systems, each manipulated variable (input signal) may affect several controlled variables (output signals) causing interaction between the input/output loops. READ MORE
