  1. 21. Predicting Xenon Oscillations in PWRs using Intrusive Reduced Order Modelling

    Författare :Kristoffer Pedersen; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Reduced Order Modeling; Modal Decomposition; Multi-Group Diffusion Theory; Xenon Oscillations;

    Sammanfattning : The increasing presence of intermittent energy sources in the Swedish electricity grid necessitates a transition of Swedish nuclear reactors from constant base load operation to load-following mode. However, such changes in power can induce xenon oscillations, a phenomenon that poses operational challenges and the risk of fuel damage. LÄS MER

    Sammanfattning : The aim of this study, ”Botanical pictures for the public: On the publication of Carl Lindman’s Bilder ur Nordens flora”, is to investigate the process of how botanical illustrations are designed and produced and how they reach their readers. The perspective is that of book history. LÄS MER

  5. 24. Empowering Women in the Middle East by Psychosocial Interventions : Can provision of learning spaces in individual and group sessions and teaching of coping strategies improve women’s quality of life?

    Författare :Hamideh Addelyan Rasi; Toomas Timpka; Alireza Moula; Kent Lindqvist; Lennart Nygren; Linköpings universitet; []
    Nyckelord :;

    Sammanfattning : Background: This study set out to construct a conceptual framework that can be used in social work with women in the Middle East and other settings where women have limited access to resources, which, as a result, limits their decision-making capacity. The framework has both an empirical and a theoretical base. LÄS MER

  7. 25. DSP based Chromatic Dispersion Equalization and Carrier Phase Estimation in High Speed Coherent Optical Transmission Systems

    Författare :Tianhua Xu; Sergei Popov; Gunnar Jacobsen; Jie Li; Seb Savory; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coherent detection; chromatic dispersion; carrier phase estimation; quadrature phase shift keying; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Sammanfattning : Coherent detection employing multilevel modulation formats has become one of the most promising technologies for next generation high speed transmission systems due to the high power and spectral efficiencies. Using the powerful digital signal processing (DSP), coherent optical receivers allow the significant equalization of chromatic dispersion (CD), polarization mode dispersion (PMD), phase noise (PN) and nonlinear effects in the electrical domain.
