    Sammanfattning : Over the last four decades the integrated circuit industry has evolved in a tremendous pace. This success has been driven by the scaling of device sizes leading to higher and higher integration capability, which have enabled more functionality and higher performance. LÄS MER

  3. 3. Model Based Enhancement of Bioimpedance Spectroscopy Analysis : Towards Textile Enabled Applications

    Författare :Rubén Buendía López; Kaj Lindecrantz; Javier Rosell-Ferrer; KTH; []

    Sammanfattning : Several signal processing approaches have been developed to overcome the effect of stray capacitances in Electrical Bioimpedance Spectroscopy (EBIS) measurements. EBIS measurements obtained with textile-enabled instrumentation are more vulnerable to stray capacitances. LÄS MER

  4. 4. Performance of Non-ceramic Insulators in Tropical Environments

    Författare :M. A. R. Manjula Fernando; Chalmers University of Technology; []
    Nyckelord :pollution; high voltage insulator; leakage current; testing;

    Sammanfattning : Non-ceramic insulators have been tested in the field and under laboratory conditions in many countries for more than three decades. Nevertheless, information about their performance in tropical environments is rather limited. Thus, this project was conducted in order to fill the gap. LÄS MER

  5. 5. Safety and biological aspects of present techniques of haemodialysis

    Författare :Per Jonsson; Hans Dietrich Polaschegg; Umeå universitet; []
    Nyckelord :haemodialysis; safety; leakage current; central dialysis catheter; microbubbles; microemboli; air contamination; transfusion medicine; transfusionsmedicin;

    Sammanfattning : Introduction: Haemodialysis (HD) is a treatment in which blood from the patient is lead through a tubing system into a dialysis device in a extracorporeal circuit. This circuit contains semipermeable membranes (dialyzer). Blood with uraemic toxins flows on one side, and a salt solution flows on the other side. LÄS MER
