  1. 1. PDEModelica – A High-Level Language for Modeling with Partial Differential Equations

    Författare :Levon Saldamli; Peter Fritzson; Bernhard Bachmann; Francesco di Casella; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mathematical modeling; PDEModelica; Modelica; object-oriented modeling; equation-based modeling; declarative modeling; high-level modeling languages; mathematical modeling languages; Computer science; Datavetenskap;

    Sammanfattning : This thesis describes work on a new high-level mathematical modeling language and framework called PDEModelica for modeling with partial differential equations. It is an extension to the current Modelica modeling language for object-oriented, equation-based modeling based on differential and algebraic equations. LÄS MER

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

    Författare :Carl-Johan Sjöstedt; Martin Törngren; Hans Vangheluwe; KTH; []

    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. 3. 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. 4. Monolithic Integrated Oscillators - Phase Noise Analysis and Inductor Modeling

    Författare :Niklas Troedsson; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; monolithic inductor; Monolithic integrated oscillator; CMOS; Bluetooth; low voltage; voltage controlled oscillator; Elektronik och elektroteknik; Electronics and Electrical technology; inductor modeling; phase noise analysis; quadrature voltage controlled oscillator;

    Sammanfattning : This doctoral dissertation studies voltage controlled oscillators (VCOs) that operate at low supply voltages. Due to smaller transistor sizes and lower supply voltage ratings with every new CMOS technology, voltage headroom is diminishing. LÄS MER

  7. 5. Adaptive Optics in Integrated Modeling of Telescopes

    Författare :Anita Enmark; Astronomi - Genomgår omorganisation; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; extremely large telescope; adaptive optics; Integrated model;

    Sammanfattning : This thesis present the implementation of a modular adaptive optics (AO) model, as part of an integrated model of extremely large telescopes (ELTs). The purpose of the project has been to establish knowledge within integrated modeling, with emphasis on adaptive optics. LÄS MER
