  2. 16. Fluctuations of smooth linear statistics of determinantal point processes

    Author : Lambert Gaultier; Kurt Johansson; Igor Krasovsky; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Abstract : We study eigenvalues of unitary invariant random matrices and other de-terminantal point processes. Paper A investigates some generalizations ofthe Gaussian Unitary Ensemble which are motivated by the physics of freefermions. READ MORE

  4. 17. Development and Investigation of Reactivity Measurement Methods in Subcritical Cores

    Author : Johanna Wright; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; source modulation method; point kinetics; core loading; reactivity measurement; Feynman-alpha formulae; Accelerator Driven Systems ADS ; subcritical cores;

    Abstract : Subcriticality measurements during core loading and in future accelerator driven systems have a clear safety relevance. In this thesis two subcriticality methods are treated: the Feynman-alpha and the source modulation method. READ MORE

  5. 18. Diluted Operation of a Heavy-Duty Natural Gas Engine - Aiming at Improved Effciency, Emission and Maximum Load

    Author : Mehrzad Kaiadi; Förbränningsmotorer; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Turbulence; Natural gas engine; Dilution limit; VGT; Cyclic variation; Closed-loop control; Heavy-duty;

    Abstract : Most heavy-duty engines are diesel operated. Severe emission regulations, high fuel prices, high technology costs (e.g. catalysts, fuel injection systems) and unsustainably in supplying fuel are enough reasons to convenience engine developers to explore alternative technologies or fuels.

  6. 19. Nonlinear Approaches to Periodic Signal Modeling

    Author : Emad Abd-Elrady; Torsten Söderström; Torbjörn Wigren; Jonas Sjöberg; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cramer-Rao bounds; frequency estimation; identification; limit cycle; nonlinear systems; periodic signals; Wiener model structure; Signal processing; Signalbehandling; Signalbehandling; Signal Processing;

    Abstract : Periodic signal modeling plays an important role in different fields. The unifying theme of this thesis is using nonlinear techniques to model periodic signals. The suggested techniques utilize the user pre-knowledge about the signal waveform. This gives these techniques an advantage as compared to others that do not consider such priors. READ MORE

  7. 20. Stochastic systems with locally defined dynamics

    Author : Anton Muratov; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; point process; sequential adsorption; stopping set; random measure; Polya urn; convergence of empirical measures; bit flipping; recurrence; mixing times; sequential adsorption;

    Abstract : This thesis considers two large classes of models related to the dynamical point processes. The first is the locally interactive sequential adsorption, or LISA, models. READ MORE
