  1. 6. Deep learning for non-intrusive sensing in turbulence with passive scalars

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Arivazhagan Geetha Balasubramanian; [2021]
    Keywords : Turbulent boundary layer; passive scalar; direct numerical simulation; Prandtl number; Machine learning; convolutional neural network; Turbulent gränsskikt; passiv skalär; direkt numerisk simulering; Prandtl-nummer; maskininlärning; faltningsneurala nätverk;

    Abstract : The near-wall modelling of turbulent flows has been an active field of research due to the computational cost associated with the direct numerical simulations of such flow, which are characterized by a wide range of length and time scales. With the recent advancements in technological capabilities, the availability of high-fidelity data has enabled the construction of data-driven approaches to model turbulence. READ MORE

  3. 7. Habitat availability and ontogenetic niche shifts : The effects on adult size of lake-living brown trout (Salmo trutta)

    University essay from Umeå universitet/Institutionen för ekologi, miljö och geovetenskap

    Author : Elin Lindmark; [2021]
    Keywords : ontogenetic niche shift; habitat availability; size structure; brown trout;

    Abstract : One common consequence of ontogenetic niche shifts is that juveniles and adults of the same species often use different resources and habitats. Theory suggests that variation in productivity and/or habitat size for the respective life stage regulates size distribution of individuals and population biomass. READ MORE

  4. 8. Spatiotemporal change of stream and wetland features over 140 years in an agricultural catchment in southern Sweden : an assessment of historical maps in GIS

    University essay from SLU/Dept. of Soil and Environment

    Author : Linnea Lindelöf; [2021]
    Keywords : historical map; wetland; stream; GIS; sinuosity index; land cover change; georeferencing; vectorizing;

    Abstract : The Swedish agricultural landscape has historically changed by draining wetlands and hydromorphological impacts by straightening and redirect watercourses. Drainage has been a part of Sweden’s agricultural history, dating back to the 13th century with its peak in the 19th and 20th centuries. READ MORE

  5. 9. Dynamics of streamflow and stream chemistry in a Swiss pre-Alpine headwater catchment : A fine scale investigation of flow occurrence and electrical conductivity in the temporary streams in the lower Studibach catchment

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Elise Baumann; Hanna Berglund; [2021]
    Keywords : Temporary Streams; Pre-Alpine Catchment; Streamflow; Stream Chemistry; Fine Scale Investigation; Electrical-conductivity; Stream Mapping; Temporära bäckar; Pre-Alpina avrinningsområden; Bäckflöden; Vattenkemi; Finskalig undersökning; Elektrisk konduktivitet; Bäck-kartering;

    Abstract : Temporary streams and their dynamics have often been largely overseen in hydrological research and there is relatively little knowledge about how the occurrence of flow in these streams varies temporally and spatially. Temporary streams are important from a hydro- logical perspective because they affect water quantity and quality in downstream peren- nial reaches, and from an ecological perspective because they provide habitat to unique species.

  6. 10. Enhancing the Decoding of Short LDPC Codes with Stochastic Sequences

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

    Author : Yuyuan Gu; Haien Li; [2021]
    Keywords : 5G; channel coding; LDPC codes; stochastic decoding; stochastic computation; Technology and Engineering;

    Abstract : Low-Density Parity-Check (LDPC) codes are one of the most popular codes used in nowadays’ communication due to their high coding efficiency at low decoding complexity. With these characteristics, LDPC codes are suitable for high-speed information transmission systems. READ MORE
