  2. 1. Advanced Spectral Analysis with Applications

    Author : Niclas Sandgren; Peter Stoica; Thomas L. Marzetta; Uppsala universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; frequency-selective spectral analysis; damped sinusoidal model; prior knowledge; multichannel spectroscopy; phantom experimental data; in-vivo in-vitro data analysis; area-selective analysis; cepstrum thresholding; total-variance reduction; two-dimensional spectral estimation; spectral smoothing; irregular sampling; CARMA signals; Signal processing; Signalbehandling;

    Abstract : Spectral analysis has advanced the last decades as a signal processing tool to extract significant information about certain properties of measured data. The practical use of spectral analysis techniques in time-series analysis has been emphasized in the immense amount of previous literature in the field and by a rapidly growing number of applications.

  4. 2. Cost efficency of nonresponse rate reduction efforts : an evaluation approach

    Author : Sara Westling; Bengt Swensson; Risto Lehtonen; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nonresponse bias; follow-ups; response distribution; resource allocation; cost efficiency; evaluation; nonresponse error; Monte Carlo simulations; Statistics; Statistik; Statistics; Statistik;

    Abstract : Nonresponse, the failure to obtain complete measurement on all sample elements, is an increasing problem in sample surveys. Efforts to reduce the nonresponse rate are expensive and their effect may not be as desired. READ MORE

  5. 3. Prospective and longitudinal human studies of lead and cadmium exposure and the kidney

    Author : Johan Nilsson Sommar; Ingvar A Bergdahl; Max Petzold; Umeå universitet; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Cadmium; end-stage renal disease; kidney; lead; longitudinal; matched case-control; mixed effects; prospective; Occupational and Environmental Medicine; arbets- och miljömedicin;

    Abstract : Cadmium and lead accumulate in humans and can have toxic effects. Exposure to cadmium is well known to cause kidney damage. Cadmium binds to metallothioneins, proteins that play a role in cadmium transport. READ MORE
