  2. 6. Control Lyapunov Functions : A Control Strategy for Damping of Power Oscillations in Large Power Systems

    Author : Mehrdad Ghandhari; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; UPFC; CSC; QBT; Lyapunov function; Control Lyapunov Function; SIME; Sliding mode; Electric power engineering; Elkraftteknik;

    Abstract : In the present climate of deregulation and privatisation, theutilities are often separated into generation, transmission anddistribution companies so as to help promote economic efficiencyand encourage competition. Also, environmental concerns,right-of-way and cost problems have delayed the construction ofboth generation facilities and new transmission lines while thedemand for electric power has continued to grow, which must bemet by increased loading of available lines.

  5. 8. Non-Suicidal Self-Injury in Swedish Adolescents : Prevalence, Characteristics, Functions and Associations With Childhood Adversities

    Author : Maria Zetterqvist; Carl Göran Svedin; Lars-Gunnar Lundh; Paul Plener; Linköpings universitet; []
    Keywords : LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Non-suicidal self-injury; adolescents; prevalence; functions; adversities; trauma symptoms;

    Abstract : Non-suicidal self-injury (NSSI), such as intentionally cutting, burning or hitting oneself, is a behavior with potentially detrimental consequences and empirical studies are necessary to gain knowledge of how to prevent NSSI in adolescents. The aims of this thesis were to investigate the prevalence, methods, characteristics and functions of NSSI in a large community sample of Swedish adolescents, and to examine the relationship between NSSI and adverse life events and trauma symptoms.

  6. 9. A Study of Smooth Functions and Differential Equations on Fractals

    Author : Anders Pelander; Anders Öberg; Svante Janson; Alexander Teplyaev; Tom Lindström; Uppsala universitet; []
    Keywords : Mathematical analysis; Analysis on fractals; p.c.f. fractals; Sierpinski gasket; Laplacian; differential equations on fractals; infinite dimensional i.f.s.; invariant measure; harmonic functions; smooth functions; derivatives; products of random matrices; Matematisk analys;

    Abstract : In 1989 Jun Kigami made an analytic construction of a Laplacian on the Sierpiński gasket, a construction that he extended to post critically finite fractals. Since then, this field has evolved into a proper theory of analysis on fractals. The new results obtained in this thesis are all in the setting of Kigami's theory. READ MORE

  7. 10. Amoebas, Discriminants, and Hypergeometric Functions

    Author : Lisa Nilsson; Mikael Passare; Maurice Rojas; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; amoeba; coamoeba; discriminant; hypergeometric functions; Mellin transform; Algebra; geometry and mathematical analysis; Algebra; geometri och analys; Mathematics; matematik;

    Abstract : This thesis consists of six chapters. In Chapter 1 we give some historical background to the topic of the thesis together with the fundamental definitions and results that the thesis is based on. In Chapter 2 we study Mellin transforms of rational functions and investigate their analytic continuations. READ MORE
