  1. 21. Improvements in Bioimpedance SpectroscopyData Analysis : Artefact Correction, ColeParameters, and Body Fluid Estimation

    Författare :Ruben Buendia; Fernando Seoane; Hermann Scharfetter; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Bioimpedance; Cole; Body Fluid;

    Sammanfattning : The estimation of body fluids is a useful and common practice in the status assessment of diseasemechanisms and treatments. Electrical bioimpedance spectroscopy (EBIS) methods are non-invasive,inexpensive, and efficient alternatives for the estimation of body fluids. However, these methods areindirect, and their robustness and validity are unclear. LÄS MER

  3. 22. Least squares modification of Stokes formula with application to the Estonian geoid

    Författare :Artu Ellmann; KTH; []
    Nyckelord :geoid; stokes formula; least sequares modification; total topographic correction; total atmospheric correction; gps levelling;

    Sammanfattning : Many applications in geodesy,geophysics and engineering require physically defined heightsrelated to an equipotential surface of the Earth, thegeoid.During the last two decades theincreased need for refined geoid models has been driven by thedemands of users of GPS, who nowadays must transformGPS-derived geodetic heights into orthometric heights, makingthem compatible with the local vertical datum.

  4. 23. Modelling and genetic correction of liver genetic diseases

    Författare :Mihaela Zabulica; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : The urea cycle is a set of biochemical reactions that converts highly toxic ammonia into urea for excretion. Deficiencies in any of the genes of the cycle can be life-threatening, with liver transplantation currently being the only definitive treatment. LÄS MER

  5. 24. Modeling and post-correction of pipeline analog-digital converters

    Författare :Samer Medawar; Peter Händel; Martin Gustafsson; KTH; []
    Nyckelord :;

    Sammanfattning : Integral nonlinearity (INL) for pipelined analog-digital converters (ADCs) operating at radio frequency is measured and characterized. A parametric model for the INL of pipelined ADCs is proposed and the corresponding least-squares problem is formulated and solved. LÄS MER
