  1. 31. Energy Saving vs. Performance: Trade-offs in Optical Networks

    Författare :Pawel Wiatr; Paolo Monti; Josep Solé-Pareta; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; energy-efficiency; optical networks; RWA; side-effects; device reliability performance; network performance; operational cost; benefits; loss; Informations- och kommunikationsteknik; Information and Communication Technology;

    Sammanfattning : The energy consumption of communication networks is continuously growing. Many energy saving approaches have been proposed at the device, system, and network level. The most promising way to address this problem is to utilize photonic technologies as much as possible thanks to their low energy consumption per bit performance. LÄS MER

  3. 32. The optic tectum of the salmon:site of interaction of neurohormonal photoperiodic and neural visual signals. The GABAergic neuronal system and melatonin receptors

    Författare :Marie Anzelius; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Animal anatomy; melatonin receptors; GABA; optic tectum; fish; brain; animal morphology; Djurs anatomi och morfologi;

    Sammanfattning : Melatonin is a neurohormone which mediates photoperiodic signals from the pineal organ to the brain. GABA (g-aminobutyric acid) is the major inhibitory transmitter in the central nervous system. LÄS MER

  4. 33. Kan symboler överföra mening? : en teoretisk diskussion om kommunikation

    Författare :Stefan Karlsson; Luleå tekniska universitet; []
    Nyckelord :;

    Sammanfattning : This work is divided into two parts - a practical/technical view of communication, followed by a change to a broader view with a theoretical language perspective. The overarching purpose is:To increase the understanding of how meaning is transferred between people through the use of symbols. LÄS MER

  5. 34. Coordinated Frequency Control Using DC Interconnections Between AC Systems : Utilizing Fast Frequency Support through HVDC Links and Evaluating the Newly Uncovered Dynamics in Low-Inertia Power Systems

    Författare :Danilo Obradovic; Robert Eriksson; Mehrdad Ghandhari; Damian Flynn; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Transmission system operators are increasingly adopting renewable energy sources in response to the escalating need to reduce environmental pollution. However, renewable energy sources, like wind and solar power, connect to the grid through power electronics, offering no inherent inertia. LÄS MER

  7. 35. Tillvaratagna effekter. Om Jan Håfströms konstnärskap och konstnärsroll

    Författare :Martin Sundberg; Avdelningen för konsthistoria och visuella studier; []
