  2. 16. Algebraic Methods for Verification and Control of Discrete Event Dynamic Systems

    Author : Jonas Plantin; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : Discrete event dynamic systems (DEDS) have become increasingly important in industry and there is a need for structured methods applicable to the design process of DEDS. In this thesis we consider algebraic methods for verification and control of DEDS.To model DEDS we use polynomials in a quotient ring. READ MORE

  4. 17. Residual generation for fault diagnosis

    Author : Erik Frisk; Lars Nielsen; Linköpings universitet; []
    Keywords : TECHNOLOGY; TEKNIKVETENSKAP;

    Abstract : The objective when supervising technical processes is to alarm an operator when a fault is detected and also identify one, or possibly a set of components, that may have been the cause of the alarm. Diagnosis is an expansive subject, partly due to the fact that nowadays, more applications have more embedded computing power and more available sensors than before. READ MORE

  5. 18. Hypergeometric functions in several complex variables

    Author : Timour Sadykov; Mikael Passare; Bernd Sturmfels; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematical analysis; Analys;

    Abstract : This thesis deals with hypergeometric functions in several complex variables and systems of partial differential equations of hypergeometric type. One of the main objects of study in the thesis is the so-called Horn system of equations: xiPi(θ)y(x) = Qi(θ)y(x), i = 1, ... READ MORE

  6. 19. Optical Analysis of biological media - continuous wave diffuse spectroscopy

    Author : Jan Sørensen Dam; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; spatially resolved diffuse reflectance; in vitro diffuse spectroscopy; continuous wave techniques; Nuclear physics; multivariate data analysis.; Kärnfysik; Fysik; Physics; Medicin människa och djur ; Medicine human and vertebrates ; Monte Carlo simulations; light propagation models; multiple scattering; Tissue optics; tissue optical properties; Fysicumarkivet A:2000:Sörensen Dam;

    Abstract : The main topic of this thesis is real-time quantification of relevant chromophores and light scattering elements in biological media. The presented methods and instrumentation are based on continuous wave (steady-state) optical measurements of (a) spatially-resolved diffuse reflectance from bulk media and (b) combined spatially-resolved and goniometric measurements of re-emitted light from thin samples.

  7. 20. Influence of transient loading on lubricant density and frictional properties

    Author : Bert-Olof Åhrström; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Maskinelement; Machine Elements;

    Abstract : This licentiate thesis deals with the influence of transient loading, at high pressures, on the pressure-dilatation relation and frictional properties of lubricants. A Split-Hopkinson pressure bar and a Ball and Bar apparatus have been used for the experiments. READ MORE
