    Sammanfattning : Introduction: There is an increasing awareness in the field of cardiology regarding the need for improved delivery of palliative care in patients with heart failure (HF). Professional guidelines have drawn attention to the importance of discussing the heart failure trajectory with patients and their families. LÄS MER

  4. 3. Flexible Circuits and Materials for Creating Large-Area RFID Reader Antenna Systems

    Författare :Xiaotian Li; Johan Sidén; Henrik Andersson; Jonny Johansson; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : One of the applications for RFID technology is to monitor and position RFID-tagged objects over large volumes. To achieve this, one possible option is to implement RFID reader antennas, which are relatively thin but with significantly large areas, and place them beneath the RFID-tagged objects. LÄS MER

  5. 4. High frequency monoloithic integrated circuits for communication systems

    Författare :Mehran Mokhtari; KTH; []
    Nyckelord :;

    Sammanfattning : The wavelengths of interest in today's communication systemfront-ends are in the same order of magnitude as the availabledevices and circuit sizes. So the wave nature of theinformation can not be neglected. LÄS MER

  7. 5. High-Speed Electroabsorption Modulators and p-i-n Photodiodes

    Författare :Robert Lewén; KTH; []
    Nyckelord :Optical communication; Fiber optic; Electroabsorption modulators; p-i-n photodiodes; transmission line; traveling wave; high-speed; microwave photonics;

    Sammanfattning : This thesis presents methods for optimization ofelectroabsorption modulators (EAM) and p-i-n photodiodes (PD)withrespect to high frequency (HF) performance. Differentreactive matching techniques are investigated such as lumpedmatching and integrated transmission line (TML) layouts includingoperation in the traveling-wave (TW) regime. LÄS MER
