1. 6. Meta-Languages and Semantics for Equation-Based Modeling and Simulation

   Författare :David Broman; Peter Fritzson; Jeremy Siek; Thomas Schön; Björn Lisper; Walid Taha; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Meta-language; semantics; EOO; Modelica; equations; modeling; simulation; MKL; Computer science; Datalogi;

   Sammanfattning : Performing computational experiments on mathematical models instead of building and testing physical prototypes can drastically reduce the develop cost for complex systems such as automobiles, aircraft, and powerplants. In the past three decades, a new category of equation-based modeling languages has appeared that is based on acausal and object-oriented modeling principles, enabling good reuse of models. LÄS MER

3. 7. Modeling and Simulation of Physical Systems in a Mechatronic Context

   Författare :Carl-Johan Sjöstedt; Martin Törngren; Hans Vangheluwe; KTH; []
   Nyckelord :mechatronics; MATLAB Simulink; SysML; bond graphs; Modelica; Simscape; simulation; modeling; EAST-ADL2; physical modeling; Mechanical engineering; Maskinteknik;

   Sammanfattning : This thesis gives different views on the modeling and simulation of physical systems, especially together with embedded systems, forming mechatronic systems. The main considered application domain is automotive. LÄS MER

4. 8. Integrated Model-Driven Development Environments for Equation-Based Object-Oriented Languages

   Författare :Adrian Pop; Peter Fritzson; Hans Vangheluwe; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Integrated Environments; Modeling; Simulation; Equation-based Object-oriented Languages; Debugging; UML-SysML; Computer science; Datalogi;

   Sammanfattning : Integrated development environments are essential for efficient realization of complex industrial products, typically consisting of both software and hardware components. Powerful equation-based object-oriented (EOO) languages such as Modelica are successfully used for modeling and virtual prototyping increasingly complex physical systems and components, whereas software modeling approaches like UML, especially in the form of domain specific language subsets, are increasingly used for software systems modeling.

5. 9. ForSyDe-Atom: Design of Heterogeneous Embedded Systems : Taming Complexity with Layers, Atoms and Patterns

   Författare :George Ungureanu; Ingo Sander; Reinhard von Hanxleden; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; system design languages; modeling; simulation; synthesis; embedded systems; cyber-physical systems; domain specific languages; systemdesignspråk; modellering; simulering; syntes; inbyggda system; cyberfysiska system; domänspecifika språk; Informations- och kommunikationsteknik; Information and Communication Technology;

   Sammanfattning : The design of embedded systems is inherently complex for two main reasons. Firstly, it entails the combined knowledge and results from a vast set of mature, well-established, yet separate disciplines, such as electrical engineering, computer science, mechanical engineering, etc. LÄS MER

7. 10. The language learning infant: Effects of speech input, vocal output, and feedback

   Författare :Lisa Gustavsson; Francisco Lacerda; Roger Moore; Stockholms universitet; []
   Nyckelord :HUMANIORA; HUMANITIES; human; language; language acquisition; perception; production; humanoid; development; model; embodied system; speech signal processing; vocal tract morphology; acoustic; speech input; information processing; scaling; interaction; growth; infant; imitation; feedback; perceptual salience; modeling; Phonetics; Fonetik; Phonetics; fonetik;

   Sammanfattning : This thesis studies the characteristics of the acoustic signal in speech, especially in speech directed to infants and in infant vocal development, to gain insight on essential aspects of speech processing, speech production and communicative interaction in early language acquisition. Three sets of experimental studies are presented in this thesis. LÄS MER
