  2. 6. Modeling Analog to Digital Converters at Radio Frequency

    Author : Niclas Björsell; Peter Händel; Niclas Keskitalo; Linus Michaeli; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ADC; Analog to Digital Converters; Signal processing; Telecommunication; Telekommunikation; Electronics;

    Abstract : Det här arbetet handlar om att ta fram beteendemodeller av analog till digital omvandlare avsedda för tillämpningar i radiofrekvensområdet. Det gäller tillämpningar inom telekommunikation men även in test- och mätinstrument där omvandlingen från analoga till digitala signaler ofta är en prestandamässig flaskhals. READ MORE

  4. 7. On particle-based online smoothing and parameter inference in general hidden Markov models

    Author : Johan Westerborn; Jimmy Olsson; Thomas Schön; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis consists of two papers studying online inference in general hidden Markov models using sequential Monte Carlo methods.The first paper present an novel algorithm, the particle-based, rapid incremental smoother (PaRIS), aimed at efficiently perform online approximation of smoothed expectations of additive state functionals in general hidden Markov models.

  6. 9. Oceanographic studies of the Baltic Sea with emphasis on sea ice and mixing processes

    Author : Christian Nohr; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Baltic Sea; Water and Heat budgets; Deep-water mixing; Internal Wavedrag; Dynamical Sea Ice production; Sea Ice dynamics;

    Abstract : This thesis comprises of model estimates of the water and heat budgets, re-estimating of the budget of deep-water mixing energy, model studies of generation mechanisms for internal waves, sea ice dynamermics and finally sea ice monitoring. Common site for all the studies are the Baltic Sea. READ MORE

  7. 10. Spectroscopic studies of dynorphin neuropeptides and the amyloid beta-peptide : The consequences of biomembrane interactions

    Author : Loïc Hugonin; Astrid Gräslund; Bernard Lebleu; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Biophysics; Biofysik; Biophysics; biofysik;

    Abstract : Dynorphin A, dynorphin B and big dynorphin are endogenous opioid neuropeptides. They play an important role in a wide variety of physiological functions such as regulation of pain processing and memory acquisition. Such actions are generally mediated through the κ-receptors. READ MORE
