  1. 11. Trends in Childbearing and Nuptiality in Sweden : A Period Analysis

    Författare :Gunnar Andersson; Kathleen Kiernan; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Demography; Demografi; Demography; demografi;

    Sammanfattning : One purpose of this thesis is to introduce a system for presenting trends in family dynamics in contemporary Sweden. We use annual indexes of birth rates in order to display trends in childbearing for Swedish women over the years since 1961. We use similar annual indexes of marriage risks and divorce risks to display nuptiality trends since 1971. LÄS MER

  3. 12. Angle Resolved Light Scattering in Turbid Media : Analysis and Applications

    Författare :Magnus Neuman; Per Edström; Torbjörn Löfqvist; Mittuniversitetet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Engineering physics; Teknisk fysik;

    Sammanfattning : Light scattering in turbid media is essential for such diverse application areas as paper and print, computer rendering, optical tomography, astrophysics and remote sensing. This thesis investigates angular variations of light reflected from plane-parallel turbid media using both mathematical models and reflectance measurements, and deals with several applications.

  5. 14. Imaging of nucleocytoplasmic transcription factor dynamics in yeast

    Författare :Kristofer Bodvard; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; transcription factor; single-cell; yeast; image analysis; Saccharomyces cerevisiae; light stress; Fluorescence microscopy; signalling;

    Sammanfattning : Fluorescence microscopy has proven to be an invaluable tool in identifying and understanding cell signalling, intracellular spatial and temporal dynamics, and cell-to-cell variability. This thesis focuses on imaging of nucleocytoplasmic transcription factor dynamics at the single cell level in yeast. LÄS MER

  7. 15. Statistical Analysis of Hardware Impairments in Communication Systems

    Författare :Mohammad Hossein Moghaddam; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Hardware impairments; distortion analysis; PA nonlinearity; phase noise; spectral analysis; pulse shaping and matched filter; IQI;

    Sammanfattning : This thesis delves into the study of hardware impairments, the inevitable limiting factors in radio frequency (RF) communication systems, and their substantial influence on system performance. It addresses the incongruity between the often stringent requirements imposed by standards and the innate imperfections of analog circuits present in real-world RF electronics. LÄS MER
