  2. 2. Modeling and Compensation of Polarization Effects in Fiber-Optic Communication Systems

    Författare :Cristian Bogdan Czegledi; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; nonlinear compensation; Channel model; model-based; polarization demultiplexing; polarization-mode dispersion; polarization drift; backpropagation; PMD; DBP;

    Sammanfattning : Optical communication systems that exploit the orthogonality between two polarizations of light convey information over optical fibers by modulating data over the two polarizations. In an idealized scenario, the two polarizations propagate through the fiber without interfering. LÄS MER

    Författare :Cristian Bogdan Czegledi; Chalmers University of Technology; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In the past decade, accessing information has become easier than ever, leading to a rapid growth in popularity of social media, online gaming, and multimedia broadcast systems. These and other services put pressure on the Internet service providers to support high-speed Internet connections and motivate the need for faster communication systems. LÄS MER

  4. 4. Designing for shared energy responsibility

    Författare :Hanna Hasselqvist; Cristian M Bogdan; Elina Eriksson; Ylva Fernaeus; Mike Hazas; KTH; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; human-computer interaction; design; sustainability; practices; energy; mobility; Människa-datorinteraktion; Human-computer Interaction;

    Sammanfattning : A significant part of the world’s carbon emissions is related to energy use for housing and personal transport, and there are many efforts to make this energy use more sustainable. In the field of Sustainable Human-Computer Interaction, there has been a great interest in exploring how interactive systems can be used to influence people’s energy use, often with a focus on providing information and encouraging energy users to change their behaviours.
