  1. 16. Switched Bond Graphs : Simulation and Analysis

    Författare :Krister Edström; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bond graphs; Hybrid systems; Modeling; Simulation; Causality; Discontinuities;

    Sammanfattning : In this thesis an approach to modeling and simulation of mode switching systems is investigated. This approach, switched bond graphs, is an extension of the bond graph language in the sense that it allows modeling of mode switching phenomena.The classical bond graph language as well as the switched bond graph language are presented.

  3. 17. Microresonator combs for coherent optical communications

    Författare :Attila Fülöp; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber-optic communication; nonlinear optics; integrated optics devices; four-wave mixing; microresonators;

    Sammanfattning : This thesis covers the study of microresonator-based optical frequency combs for use in coherent optical communication links. Current links typically utilize several free-running lasers to achieve wavelength-division multiplexing (WDM). LÄS MER

  4. 18. Inference techniques for stochastic nonlinear system identification with application to the Wiener-Hammerstein models

    Författare :Giuseppe Giordano; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear systems; system identification; stochastic; Maximum Likelihood; Wiener-Hammerstein; Monte Carlo; Newton s method;

    Sammanfattning : Stochastic nonlinear systems are a specific class of nonlinear systems where unknown disturbances affect the system's output through a nonlinear transformation. In general, the identification of parametric models for this kind of systems can be very challenging. LÄS MER

  5. 19. Modelling the offset lithographic printing process

    Författare :Cristofer Englund; Högskolan i Halmstad; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Neural networks; Self-organizing map; Data mining; Outlier detection; Leverages; Committee; Adaptive modelling; Image analysis; Bildanalys;

    Sammanfattning : A concept for data management and adaptive modelling of the offset lithographic printing process is proposed. Artificial neural networks built from historical process data are used to model the offset printing process aiming to develop tools for online ink flow control. LÄS MER

  7. 20. Some Results on Distinguishing Attacks on Stream Ciphers

    Författare :Håkan Englund; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; correlation attack; irregularly clocked filter generator; distinguishing attacks; Stream ciphers; filter generator; Pomaranch; Dragon; LILI-128; LILI-II;

    Sammanfattning : Stream ciphers are cryptographic primitives that are used to ensure the privacy of a message that is sent over a digital communication channel. In this thesis we will present new cryptanalytic results for several stream ciphers. LÄS MER
