    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ultrasound; Sample preparation; Particle manipulation; Fysik; Physics; Biological Physics; Biologisk fysik;

    Abstract : Acoustofluidics has become a well-established technology in the lab-on-a-chip scientific community. The technology involves primarily the manipulation of fluids and/or particles in microfluidic systems. READ MORE

  3. 3. Essays on Sample Surveys : Design and Estimation

    Author : Edgar Bueno; Per Gösta Andersson; Maria Giovanna Ranalli; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; GREG estimator; mixture distribution; probability proportional to size sampling; sampling algorithms; sampling design; sampling strategy; survey sampling; stratified sampling; Statistics; statistik;

    Abstract : Sampling is a core stage in every survey. A sampling design carefully elaborated may imply not only a more accurate estimation of the parameters of interest, but also a reduction in the required sample size in a study. In this thesis we consider two particular but connected subjects. READ MORE

  4. 4. On chip integrated sample preparation for proteomics

    Author : Simon Ekström; Avdelningen för Biomedicinsk teknik; []
