  1. 1. Mixing patterns in Rushton-turbine-agitated reactors

    Author : Fabrice Guillard; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food and drink technology; coherent mixing structure; geometrical analysis; dynamic structural analysis; conditional sampling; laser-induced fluorescence; mixing; stirred tank; Livsmedelsteknik;

    Abstract : This Ph.D. Thesis concerns the study of mixing in Rushton turbine agitated reactors. In industrial (bio)reactors, mixing is recognised as a limiting factor that significantly affects the performance of the process. READ MORE

  2. 2. Classification of Remotely Sensed Data Utilising the Autocorrelation between Spatio-Temporal Neighbours

    Author : Ann-Marie Flygare; Sweden Umeå Umeå University Department of Mathematical Statistics; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Image classification; strong mixing; spatio-temporal model; autocorrelation model; autocorrelation estimator; robustness aspects; strong consistency; asymptotic normality; evaluation; Statistik; Statistics;

    Abstract : The subject of this thesis is methods for classifying land using satellite images, and adherent parameter estimation. A satellite image consists of a set of pixels where measurements of spectral intensities are observed. Based on these spectral intensities, each pixel is assigned a class. READ MORE

  3. 3. Three-wave mixing in Josephson travelling-wave parametric amplifiers

    Author : Hampus Renberg Nilsson; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; three-wave mixing; lumped-element; four-wave mixing; SNAIL; Josephson junction; travelling-wave parametric amplifier; parametric amplifier; parametric amplification; resonant phase matching.; rf-SQUID;

    Abstract : This work explores possibilities of building a wide-band, quantum-limited low-noise amplifier by means of three-wave mixing (3WM) in different kinds of Josephson travelling-wave parametric amplifiers (TWPAs). We extend the theory of the continuous three-mode model to include any number of up-converted modes in the small frequency limit where the frequency dispersion is close to linear. READ MORE

  4. 4. Ocean mixing and polynyas at Maud Rise, Weddell Sea

    Author : Martin Mohrmann; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Oceanography; Weddell Sea; Southern Ocean; Maud Rise; Polynya; Frontal mixing;

    Abstract : The Weddell Sea Polynya is an intermittent, ice free area in the marginal ice zone with an extent of up to 350 000 km². It was first observed by satellites in the winter seasons of 1974-1976. In 2016 and 2017, an open-ocean polynya opened over the Maud Rise oceanic plateau in the eastern Weddell Sea, which was the largest since the 70’s. READ MORE

  5. 5. Correlation Functions in Integrable Theories : From weak to strong coupling

    Author : Raul Pereira; Joseph Minahan; Sergey Frolov; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Superstring theory; AdS CFT correspondence; Integrable field theories; Hexagon form factors; Theoretical Physics; Teoretisk fysik;

    Abstract : The discovery of integrability in planar N=4 super Yang-Mills and ABJM has enabled a precise study of AdS/CFT. In the past decade integrability has been successfully applied to the spectrum of anomalous dimensions, which can now be obtained at any value of the coupling. READ MORE
