  2. 1. Magnetic Leakage Fields and End Region Eddy Current Power Losses in Synchronous Generators

    Author : Birger Marcusson; Urban Lundin; Göran Engdahl; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; magnetic leakage fields; leakage flux; eddy currents; losses; synchronous generator; Engineering Science with specialization in Science of Electricity; Teknisk fysik med inriktning mot elektricitetslära;

    Abstract : The conversion of mechanical energy to electrical energy is done mainly with synchronous generators. They are used in hydropower generators and nuclear plants that presently account for about 80% of the electric energy production in Sweden. READ MORE

  4. 2. Low-Power Clocking and Circuit Techniques for Leakage and Process Variation Compensation

    Author : Martin Hansson; Atila Alvandpour; Ram Krishnamurthy; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Low-power; resonant clocking; multi-GHz; CMOS; leakage tolerance; low-leakage techniques; process variation; process variation compensation; Electronics; Elektronik;

    Abstract : 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. READ MORE

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

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

    Abstract : 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. READ MORE

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

    Author : M. A. R. Manjula Fernando; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; pollution; high voltage insulator; leakage current; testing;

    Abstract : 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. READ MORE

  7. 5. Gallium arsenide based buried heterostructure laser diodes with aluminium-free semi-insulating materials regrowth

    Author : Carlos Angulo Barrios; KTH; []
    Keywords : semiconductor lasers; in-plane lasers; VCSELs; GaAs; GaInP; semi-insulating materials; hydride vapour phase epitaxy; regrowth; buried heterostructure; leakage current; simulation;

    Abstract : Semiconductor lasers based on gallium arsenide and relatedmaterials are widely used in applications such as opticalcommunication systems, sensing, compact disc players, distancemeasurement, etc. The performance of these lasers can beimproved using a buried heterostructure offering lateralcarrier and optical confinement.
