2. 1. Electromagnetic characterization of power electronic systems

   Author : Mathias Enohnyaket; Mats Alaküla; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

   Abstract : Propelled by increased global awareness and demand for clean energy systems, there is a growing trend in transportation, utility, industrial, and residential applications towards the utilisation of power electronic systems with enhanced power ow controllability and eciency. Examples of power electronics applications include terminal converters in high-voltage direct Current (HVDC) transmission; exible AC transmission systems (FACTS); and converters to interface alternative energy systems such as wind turbines to the grid, variable-speed motor drives in pump systems, vehicular propulsion systems, air-conditioners, and refrigerators.

4. 2. Real-Time Services in Packet-Switched Networks for Embedded Applications

   Author : Xing Fan; Högskolan i Halmstad; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; embedded systems; real-time communication; packet-switching; swithed Ethernet; FCFS and EDF scheduling; schedulability analysis; active networking; protocol overhead; Computer science; Datalogi; Computer science; Datavetenskap;

   Abstract : Embedded applications have become more and more complex, increasing the demands on the communication network. For reasons such as safety and usability, there are real-time constraints that must be met. Also, to offer high performance, network protocols should offer efficient user services aimed at specific types of communication. READ MORE

5. 3. On conceptual modelling of mode switching systems

   Author : Ulf Söderman; Linköpings universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

   Abstract : This thesis deals with fundamental issues underlying the systematic construction of behaviour models of physical systems, especially man made engineering systems. These issues are important for the design and development of effective computer aided modelling systems providing high-level support for the difficult task of modelling. READ MORE

6. 4. Analysis and Design of Hybrid Systems

   Author : Stefan Pettersson; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; asymptotic stability; Lyapunov theory; exponential stability; piecewise quadratic Lyapunov functions; hybrid systems; stability; linear matrix inequalities; nonlinear systems; LMIs; control theory; fuzzy systems;

   Abstract : Many physical systems today are modeled by interacting continuous and discrete event systems. Such hybrid systems contain both continuous and discrete states that influence the dynamic behavior. READ MORE

7. 5. Overload control strategies for distributed communication networks

   Author : Maria Kihl; Institutionen för elektro- och informationsteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; resource allocation; simulation models; TINA; Intelligent Networks; distributed systems; performance analysis; overload control; Telecommunication engineering; Telekommunikationsteknik;

   Abstract : In distributed communication networks several nodes interact to carry out services. New telecommunication networks support a variety of services, much different from traditional telephony. Each service has its own so called load profile, which means that the amount of capacity needed to complete a service varies. READ MORE
