  2. 1. Parameter Estimation in Linear Descriptor Systems

    Author : Markus Gerdin; Linköpings universitet; []
    Keywords : differential-algebraic equations; descriptor systems; identification; TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : Linear descriptor systems form the natural way in which linear models of physical systems are delivered from an object-oriented modeling tool like Modelica. Linear descriptor systems are also known as linear differential-algebraic equations in the continuous-time case. READ MORE

  4. 2. Some Results On Optimal Control for Nonlinear Descriptor Systems

    Author : Johan Sjöberg; Torkel Glad; Xiaoming Hu; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Optimal Control; Descriptor Systems; Differential-Algebraic Systems; Controllability Function; Observability Function; Automatic control; Reglerteknik;

    Abstract : I denna avhandling studeras optimal återkopplad styrning av olinjära deskriptorsystem. Ett deskriptorsystem är en matematisk beskrivning som kan innehålla både differentialekvationer och algebraiska ekvationer. READ MORE

  5. 3. Computer Vision for Traffic Surveillance Systems : Methods and Applications

    Author : Saleh Javadi; Mattias Dahl; Michael Cree; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Intelligent transportation systems; ITS; Computer visions systems; Systemteknik; Systems Engineering;

    Abstract : Computer vision solutions play a significant role in intelligent transportation systems (ITS) by improving traffic flow, safety and management. In addition, they feature prominently in autonomous vehicles and their future development. The main advantages of vision-based systems are their flexibility, coverage and accessibility. READ MORE

  6. 4. Identification and Estimation for Models Described by Differential-Algebraic Equations

    Author : Markus Gerdin; Torkel Glad; Lennart Ljung; Manfred Deistler; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Differential-Algebraic Equations; Identifiability; Nonlinear systems; Modelling; Identification; Descriptor systems; Automatic control; Reglerteknik;

    Abstract : Differential-algebraic equations (DAEs) form the natural way in which models of physical systems are delivered from an object-oriented modeling tool like Modelica. Differential-algebraic equations are also known as descriptor systems, singular systems, and implicit systems. READ MORE

  7. 5. Reactivity of Transition-Metal Compounds from Electronic Structure

    Author : Aleksandra Vojvodic; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; magnetic edge states; electronic structure; density-functional theory; growth; surface states and resonances; nitrides; density of states; hydrodesulphurisation; sulphides; steam reforming; transition-metal carbides; Bronsted-Evans Polanyi relation; scaling relations; adsorption; descriptor; reactivity; catalysis;

    Abstract : Transition-metal carbides (TMC's), nitrides, and sulfides belong to the class of materials known as transition-metal compounds (TMX's). Besides having intriguing properties, these materials are relevant for, e.g., growth and catalysis. READ MORE
