  1. 11. Enhancing Model-Based Development of Embedded Systems : Modeling, Simulation and Model-Transformation in an Auotmotive Context

    Författare :Tahir Naseer Qureshi; Martin Törngren; De-Jiu Chen; Ramin Tavakoli Kolagari; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The increased usage of embedded computer systems in products like automobiles has not only introduced new innovations, additional safety and comfort but also increased the product and development complexity. Several model-based development (MBD) approaches have been proposed to support the management of such complexity. LÄS MER

  3. 12. Model based aircraft design : high angle of attack aerodynamics and weight estimation methods

    Författare :Christopher Jouannet; John Fielding; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This thesis addresses modelling of high angle of attack aerodynamic characteristics and weight estimation for highly maneuverable aircraft during conceptual design. In order to allow configuration selection with sufficient confidence, especially with unconventional configurations, high angle of attack aerodynamic prediction and weight estimations methods need to be improved.

  4. 13. Analysis of Synchronous machine dynamics using a novel equivalent circuit model

    Författare :Christer Danielsson; Chandur Sadarangani; Göran Engdahl; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Synchronous machine; Equivalent circuit; Magnetic equivalent circuit model; Simulation model; Parameter determination; Electric power engineering; Elkraftteknik;

    Sammanfattning : This thesis investigates simulation of synchronous machines using a novel Magnetic Equivalent Circuit (MEC) model. The proposed model offers sufficient detail richness for design calculations, while still keeping the simulation time acceptably short. Different modeling methods and circuit alternatives are considered. LÄS MER

  5. 14. Model calibration methods for mechanical systems with local nonlinearities

    Författare :Yousheng Chen; Andreas Linderholt; Thomas Abrahamsson; Gaëtan Kerschen; Linnéuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; model calibration; finite element modelling; nonlinear structural dynamics; pre-test planning; multi-sinusoidal excitation; vibrational testing; cross validation; Maskinteknik; Mechanical Engineering;

    Sammanfattning : Most modern product development utilizes computational models. With increasing demands on reducing the product development lead-time, it becomes more important to improve the accuracy and efficiency of simulations. LÄS MER

  7. 15. Kommunala ideal och politisk verklighet. : En jämförande fallstudie av frisinnad politisk organisering i Filipstad och Skövde, ca 1880-1920

    Författare :Anders Forsell; Martin Åberg; Martin Stolare; Fredrik Eriksson; Karlstads universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; liberalism; political parties; mobilization; origins of political parties; local politics; municipal affairs; democratization; politicization; political processes; case-oriented comparison; political process-model.; History; Historia;

    Sammanfattning : Most studies of emerging Swedish parties and politics have mainly focused on the Swedish Social Democrats and their struggle for democracy and political power, most as a prelude  to the so called ”Swedish Model”. Competing parties have received attention from historians on the national level, but their local origin remains to large extent an open field. LÄS MER
