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

    Author : Levon Saldamli; Peter Fritzson; Bernhard Bachmann; Francesco di Casella; Linköpings universitet; []
    Keywords : 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;

    Abstract : 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. READ MORE

  4. 22. Elliptical Adaptive Structuring Elements for Mathematical Morphology

    Author : Anders Landström; Jesús Angulo; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; Signal Processing;

    Abstract : As technological advances drives the evolution of sensors as well as the systems using them, processing and analysis of multi-dimensional signals such as images becomes more and more common in a wide range of applications ranging from consumer products to automated systems in process industry. Image processing is often needed to enhance or suppress features in the acquired data, enabling better analysis of the signals and thereby better use of the system in question. READ MORE

  5. 23. Environment support for building structured mathematical models

    Author : Johan Herber; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis is about two topics. It describes a high-level programming environment for scientific computing, called ObjectMath, and several contributions to this environment. It also analyses the concept of software development environment architecture, in particular with respect to the ObjectMath environment. READ MORE

  6. 24. Contributions to mathematical knowledge and its acquisition

    Author : Andrejs Dunkels; Luleå tekniska universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Mathematics Education; Matematik och lärande;

    Abstract : This is a thesis in mathematics with didactical emphasis. The interest of didactics of mathematics is in mathematics in relation to how it is learned. The thesis comprises three parts, A, B, and C. Part A reports in three papers from research in mathematics within potential theory. READ MORE

  7. 25. Concepts and Algorithms for Non-Linear System Identifiability

    Author : Torbjörn Andersson; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Recently, commutative algebra and differential algebra have come to use as mathematical tools for solving problems in automatic control. We will use these tools to answer questions regarding identifiability for models given as a set of differential polynomials. READ MORE
