  1. 6. Annealing Based Optimization Methods for Signal Processing Applications

    Författare :Per Persson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; combinatorial optimization; annealing; digital filter design; adaptive filtering;

    Sammanfattning : In this thesis, a class of combinatorial optimization methods rooted in statistical mechanics and their use in signal processing applications will be discussed. The thesis consists of two separate parts. LÄS MER

  3. 7. Gas exchange with a reflecting system for inhalational anaesthesia

    Författare :Louise Walther Sturesson; Anestesiologi och intensivvård; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; anesthetic conserving device; inhalational anaesthesia; carbon dioxide; Gas exchange;

    Sammanfattning : In order to reduce comsumption of inhalational anaesthetsics during high flow anaesthesia a system open in regard to oxygen, nitogen and nitrous oxide, but closed to inhalational anaesthetics, was developed. This was achieved by a reflecting filter for inhalational anaesthetics made of active carbon. LÄS MER

  4. 8. Receiver Front-Ends in CMOS with Ultra-Low Power Consumption

    Författare :Carl Bryant; Institutionen för elektro- och informationsteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; receiver; front-end; sensor networks; CMOS; ultra-low power; low noise amplifier; mixer; voltage-controlled oscillator; frequency divider; bluetooth;

    Sammanfattning : Historically, research on radio communication has focused on improving range and data rate. In the last decade, however, there has been an increasing demand for low power and low cost radios that can provide connectivity with small devices around us. LÄS MER

  5. 9. Molecular methods in malaria control in the era of pre-elimination

    Författare :Ulrika Morris; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : Increased funding combined with effective malaria control methods for prevention, diagnosis, and treatment, has resulted in a 30% reduction of the global malaria burden over the last decade. As malaria prevalence declines in areas of successful malaria control, the proportion of subpatent infections that fall below the detection level of malaria rapid diagnostic tests (RDTs) and microscopy increases.

  7. 10. Functional Layer-by-Layer films and aerogels of cellulose nanofibrils

    Författare :Erdem Karabulut; Lars Wågberg; Joseph B. Schlenoff; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : This thesis deals with the preparation of functional Layer-by-Layer (LbL) films of cellulose nanofibrils (CNFs) and polyelectrolytes. LbL films ranging in thickness from 10 nm to 5 μm were deposited onto both solid surfaces and porous nanocellulose aerogels in order to prepare functional surfaces and materials. LÄS MER
