  2. 1. Power Consumption and Joint Signal Processing in Fiber-Optical Communication

    Author : Lars Lundberg; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coherent detection; erbium-doped fiber amplifier; phase-tracking; optical amplifier; optical frequency comb; digital signal processing; carrier-recovery; spatial division multiplexing; power consumption; Fiber-optical communication; multicore fiber; Raman amplification; energy-efficiency;

    Abstract : The power consumption of coherent fiber-optical communication systems is becoming increasingly important, for both environmental and economic reasons. The data traffic on the Internet is increasing at a faster pace than that at which optical network equipment is becoming more energy efficient, which means that the overall power consumption of the Internet is increasing.

  5. 3. Development of Magnetomotive Ultrasound Imaging

    Author : Maria Evertsson; Avdelningen för Biomedicinsk teknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Magnetomotive ultrasound; molecular imaging; contrast angents; multimodal imaging; sentinel lymph node;

    Abstract : The earlier abnormalities coupled with disease can be discovered in the body, the larger is the chance to survive the disease. Molecular imaging is a growing research field which aims to detect these abnormalities at a molecular level, when the chance of survival is still high. READ MORE
