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

   Författare :Cristian Bogdan Czegledi; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; 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

5. 4. Designing for shared energy responsibility

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

   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.
