  1. 6. Modeling and Calibration of Preparative Chromatography

    Författare :Niklas Borg; Institutionen för kemiteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Chromatography; Modeling; Simulation; Calibration; Model based analysis;

    Sammanfattning : In my thesis, I have modeled adsorption chromatography and simulated, calibrated, and analyzed models of adsorption chromatography. While my main focus has been modeling and calibration of the models by estimating the parameters, the models used have been partly new. LÄS MER

  2. 7. Systems of Linear First Order Partial Differential Equations Admitting a Bilinear Multiplication of Solutions

    Författare :Jens Jonasson; Stefan Rauch; Sergio Benenti; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; Cauchy–Riemann equations; holomorphic functions; algebra; MATHEMATICS; MATEMATIK;

    Sammanfattning : The Cauchy–Riemann equations admit a bilinear multiplication of solutions, since the product of two holomorphic functions is again holomorphic. This multiplication plays the role of a nonlinear superposition principle for solutions, allowing for construction of new solutions from already known ones, and it leads to the exceptional property of the Cauchy–Riemann equations that all solutions can locally be built from power series of a single solution z = x + iy ∈ C.

  3. 8. Model Order Reduction with Rational Krylov Methods

    Författare :K. Henrik A. Olsson; Axel Ruhe; Volker Mehrmann; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Model order reduction; dual rational Arnoldi; rational Krylov; moment matching; eigenvalue computation; stability analysis; heat exchanger model; Numerical analysis; Numerisk analys;

    Sammanfattning : Rational Krylov methods for model order reduction are studied. A dual rational Arnoldi method for model order reduction and a rational Krylov method for model order reduction and eigenvalue computation have been implemented. It is shown how to deflate redundant or unwanted vectors and how to obtain moment matching. LÄS MER

  4. 9. Residual Generation Methods for Fault Diagnosis with Automotive Applications

    Författare :Carl Svärd; Mattias Nyberg; Mogens Blanke; Linköpings universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Diagnosis; fault diagnosis; FDI; fault detection; residual; residual generation; residual generator; DAE; Systems engineering; Systemteknik;

    Sammanfattning : The problem of fault diagnosis consists of detecting and isolating faults present in a system. As technical systems become more and more complex and the demands for safety, reliability and environmental friendliness are rising, fault diagnosis is becoming increasingly important. LÄS MER

  5. 10. Modeling and Control of Flexible Manipulators

    Författare :Stig Moberg; Svante Gunnarsson; Bruno Siciliano; Linköpings universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Modeling; identification; control; robot manipulator; DAE; flexible multibody dynamics; inverse dynamics; benchmark; Automatic control; Reglerteknik;

    Sammanfattning : Industrial robot manipulators are general-purpose machines used for industrial automation in order to increase productivity, flexibility, and product quality. Other reasons for using industrial robots are cost saving, and elimination of hazardous and unpleasant work. LÄS MER
