  1. 6. Phase transitions in novel superfluids and systems with correlated disorder

    Författare :Hannes Meier; Mats Wallin; Asle Sudbø; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; condensed matter physics; phase transitions; critical phenomena; spin models; quantum phase transitions; quantum fluids; superfluidity; superconductivity; disordered systems; Bose glass; dirty bosons; vortex pinning; statistical mechanics; Monte Carlo simulation; Wolff algorithm; classical worm algorithm; Wang-Landau algorithm; Fysik; Physics;

    Sammanfattning : Condensed matter systems undergoing phase transitions rarely allow exact solutions. The presence of disorder renders the situation  even worse but collective Monte Carlo methods and parallel algorithms allow numerical descriptions. LÄS MER

    Sammanfattning : Over the last decade there has been an explosive growth in the use of wireless mobile communications. Second generations systems are mature technologies now and third generation systems and beyond are being implemented and researched. LÄS MER

  5. 9. The dynostatic algorithm in adult and paediatric respiratory monitoring

    Författare :Sören Söndergaard; Göteborgs universitet; []
    Nyckelord :monitoring; respiratory mechanics; lung model; fibre optic pressure measurement; alveolar pressure; dynostatic algorithm;

    Sammanfattning : Introduction: Positive pressure ventilation carries a risk of aggravating systemic and lung disease. Monitoring of ventilatory pressure and volume is important to minimize this risk. Conventionally, the pressure of the respiratory system is measured outside the patient. LÄS MER

  7. 10. MIMO Decoding Algorithm and Implementation

    Författare :Zhan Guo; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Telecommunication engineering; Elektronik; Electronics; Signalbehandling; Signal processing; ASIC; VLSL; MIMO; Sphere Decoder; Telekommunikationsteknik; Electrical engineering; Elektroteknik;

    Sammanfattning : Multi-Input Multi-Output system has been one of the hot technologies for future wireless communications, since it can increase the capacity (coverage or link quality in other senses) at no cost in frequency spectrum. This doctoral thesis investigates improvements to MIMO decoding algorithms and presents VLSI implementation results. LÄS MER
