  2. 1. Norm-Regulation of Agent Systems : Instrumentalizing an algebraic approach to agent system norms

    Author : Magnus Hjelmblom; Magnus Boman; Jan Odelstad; Kim Solin; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Agent System; Norm-regulated; Norm-governed; Normative MAS; Normative Positions; Normative system; Transition system; Computer and Systems Sciences; data- och systemvetenskap;

    Abstract : An architecture for norm-regulated multi-agent systems based on an algebraic approach to normative systems is instrumentalized and further developed. The core of the instrumentalization is a Prolog module, which together with a Java library can be used for creating client/server-based runtime systems. READ MORE

  4. 2. The role of fault management in the embedded system design

    Author : Carlo Vitucci; Daniel Sundmark; Thomas Nolte; Fredrik Asplund; Mälardalens universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fault Management; Resilient system; Recovery methodology.; Computer Science; datavetenskap;

    Abstract : In the last decade, the world of telecommunications has seen the value ofservices definitively affirmed and the loss of the connectivity value. This changeof pace in the use of the network (and available hardware resources) has ledto continuous, unlimited growth in data traffic, increased incomes for serviceproviders, and a constant erosion of operators’ incomes for voice and ShortMessage Service (SMS) traffic.

  5. 3. Efficient Simulation Methods of Large Power Systems with High Penetration of Renewable Energy Resources : Theory and Applications

    Author : Ebrahim Shayesteh; Lennart Söder; Enrique Acha; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Power system simplification; power system reduction; power system aggregation; power system equivalencing; renewable energy resources; wind power modelling; storage allocation problem; spinning reserve determination; multi-area power system analyses; power system operation and planning; electricity market analysis.; Electrical Engineering; Elektro- och systemteknik;

    Abstract : Electrical energy is one of the most common forms of energy these days. Consequently, electric power system is an indispensable part of any society. READ MORE

  6. 4. Schrödinger Operators in Waveguides

    Author : Tomas Ekholm; Timo Weidl; Ari Laptev; Pavel Exner; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Schrödinger Operators; Hardy Inequalities; Mathematical physics; Matematisk fysik;

    Abstract : In this thesis, which consists of four papers, we study the discrete spectrum of Schrödinger operators in waveguides. In these domains the quadratic form of the Dirichlet Laplacian operator does not satisfy any Hardy inequality. READ MORE

  7. 5. Power System Oscillations - Detection, Estimation and Control

    Author : Morten Hemmingsson; Industriell elektroteknik och automation; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Elektroteknik; oscillation; power system; damping; power swing; distance protection; detection; estimation; real-time; reactive co-variation; control; Electrical engineering; load modulation; Automation; robotics; control engineering; Automatiska system; robotteknik; reglerteknik;

    Abstract : The topic of this thesis is the electro-mechanical oscillations which to some extent always are present in a power system. The demand of electric power is ever increasing. At the same time, the tolerance of disruptions in the power supply is decreasing. READ MORE
