  2. 1. Analysis of VSC-based HVDC systems

    Author : Georgios Stamatiou; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HVDC; MMC; MTDC; Poor damping; Symbolic eigenvalue expressions; Droop control; Passivity Analysis; Net damping; Frequency Domain Analysis; VSC;

    Abstract : The main objective of this thesis is to perform stability and control studies in the area of VSC-HVDC systems. A major part of the investigation focuses on the development of procedures, whose aim is to understand, explain and avoid poorly-damped conditions or instability that may appear due to dc-side resonances, which stem from the interaction of converters and passive elements in such systems.

  4. 2. Renormalization of Lorenz Maps

    Author : Björn Winckler; Marco Martens; Michael Benedicks; Welington de Melo; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematical analysis; Analys;

    Abstract : This thesis is a study of the renormalization operator on Lorenz αmaps with a critical point. Lorenz maps arise naturally as first-return maps for three-dimensional geometric Lorenz flows. Renormalization is a tool for analyzing the microscopic geometry of dynamical systems undergoing a phase transition. READ MORE

  5. 3. A Modeling Language for the Description and Development of Tool Chains for Embedded Systems

    Author : Matthias Biehl; Törngren Martin; Hans Vangheluwe; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Tool Chain; Tool Integration; Domain-Specific Modeling Language; Generative Approach; Lifecycle Support for Embedded System Development;

    Abstract : The development of embedded systems is typically supported by a number of diverse development tools. To achieve seamless tool support throughout the embedded systems development process, tool chains are constructed as software solutions that integrate the development tools. READ MORE

  6. 4. Complex Cavity Analysis : Analytical Fluid-Power Models Using CAD Information

    Author : Magnus Sethson; Richard T. Burton; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : This thesis covers different methods of topology search for making time-domain simulation models based on geometric information. The application is in the field of fluid-power. Automatic methods for extracting simulation models from CAD data are presented. READ MORE

  7. 5. The plurisubharmonic Mergelyan property

    Author : Lisa Hed; Urban Cegrell; Anders Fällström; Per Åhag; Jan Wiegerinck; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Complex Monge-Ampère operator; approximation; plurisubharmonic function; subextension; Mergelyan property; plurisubharmonic function on compact sets; Jensen measures; Mathematics; matematik;

    Abstract : In this thesis, we study two different kinds of approximation of plurisubharmonic functions. The first one is a Mergelyan type approximation for plurisubharmonic functions. READ MORE
