    Abstract : Climate change has often been framed as a global issue but slow progress in the global climate negotiations and an increasing need to plan for local adaptation have made it increasingly salient to also discuss the potential of other arenas for climate policy and knowledge production. This dissertation analyzes the interplay between science and policy at the international regional level based on a study of an assessment of the impacts of climate change in the Arctic. READ MORE

  3. 3. Towards Energy Efficient Protocols for Active RFID

    Author : Björn Nilsson; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The absence of a global standard is a bottleneck when using Radio FrequencyIdentification (RFID) technology. This thesis explores data communication protocols forActive-RFID regarding their energy efficiency and how they can be suited to fit a largevariety of applications.The use of Radio Frequency Identification systems (RFID) is growing rapidly.

  4. 4. Energy Efficient Protocols for Active RFID

    Author : Björn Nilsson; Chalmers University of Technology; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; wake-up radio; energy consumption; energy efficient; Active RFID; protocol; RFID; throughput; back-off; RFID-system; delay;

    Abstract : Radio frequency identification (RFID) systems come in different flavours; passive, active, semi-passive, or semi-active. Those different types of RFID are supported by different, internationally accepted protocol standards as well as by several accepted proprietary protocols. READ MORE
