    Abstract : Nonlinear systems occur in industrial processes, economical systems, biotechnology and in many other areas. The thesis treats methods for system identification and control of such nonlinear systems, and applies the proposed methods to a solar heating/cooling plant. READ MORE

  3. 3. Extremum Seeking Control Stability, Accuracy, and Applications

    University dissertation from Luleå tekniska universitet

    Author : Khalid Atta; [2015]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Abstract : In many applications, there is a variable that indicates the overall performance and that must be maximized, such as the output of a hydro power turbine or a mineral processing plant, or that must be minimized, such as CO2 emissions or the consumption of resources. Extremization of this variable (maximization or minimization) through adjusting the influencing manipulated variables is occasionally required without prior knowledge of the optimal values of the manipulated variables or of the optimized variable.

  5. 5. Flexible Information-Flow Control

    University dissertation from Stockholm : Mekanik

    Author : Daniel Schoepe; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; software security; information-flow control; program verification; language-based security;

    Abstract : As more and more sensitive data is handled by software, its trustworthiness becomes an increasingly important concern. This thesis presents work on ensuring that information processed by computing systems is not disclosed to third parties without the user's permission; i.e. to prevent unwanted flows of information.
