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

    Master-uppsats, KTH/Strömningsmekanik och Teknisk Akustik

    Författare :Arivazhagan Geetha Balasubramanian; [2021]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 2. How Topography Influences the Fate of Human Neural Progenitor Cells

    Master-uppsats, Lunds universitet/Tillämpad biokemi; Lunds universitet/Beräkningskemi

    Författare :Jacob Karlström; [2020]
    Nyckelord :biomaterials; cell culture; electrospinning; nanofibers; 3d; neural progenitor cells; in vitro models; nanotopography; blebbistatin; mechanotransduction; nucleus analysis; immunocytochemistry; differentiation; applied biochemistry; tillämpad biokemi; Biology and Life Sciences; Technology and Engineering;

    Sammanfattning : Novel biomimetic three-dimensional scaffolds have emerged over the last decades, and are promising for applications in regenerative therapies, as well as in in vitro disease modelling and drug testing. Thanks to their added dimension, these scaffolds are able to more accurately mimic the topography of native cellular microenvironments compared to traditionally used two-dimensional culture substrates.

  4. 3. Radon och grundläggningsmetoder : Att utforma allmänna föreskrifter

    Uppsats för yrkesexamina på grundnivå, Umeå universitet/Institutionen för tillämpad fysik och elektronik

    Författare :Klas Beyer; [2018]
    Nyckelord :;

    Sammanfattning : Radon är en radioaktiv gas som förekommer överallt i marken. Radongas kan ta sig in i byggnader via hushållsvattnet och byggmaterial, men den främsta anledningen till höga radonhalter i inomhusluften är markradon som tar sig in via grundkonstruktionen. LÄS MER

  5. 4. Mobility, habitat selection and population connectivity of Lycaena helle in central Sweden : implications for conservation

    Master-uppsats, SLU/Dept. of Ecology

    Författare :Hanna Modin; [2018]
    Nyckelord :Lycaena helle; violet copper; Lepidoptera; Lycaenidae; mobility; dispersal; resource selection function; habitat selection; connectivity; metapopulation; stepping stone;

    Sammanfattning : Lycaena helle is an endangered butterfly that is mainly threatened by habitat degradation and fragmentation. For all species with a fragmented distribution, knowledge about mobility, habitat requirements and connectivity is key to developing successful conservation strategies. LÄS MER

  7. 5. Design and Test of: Wide Band and Highly Polarized Antenna for 60GHz

    Kandidat-uppsats, Uppsala universitet/Institutionen för teknikvetenskaper

    Författare :David Larsson; [2017]
    Nyckelord :antenna; microwaves; millimetre wave; 60 GHz;

    Sammanfattning : In this work  high gain antennas are investigated for the 60 GHz frequency. The goal is to produce a high bandwidth point-to-point wireless network that could enable improved and new features in embedded systems used to detect particles in high energy physics. A literature study was performed aiming at simple, high gain, highly polarised antennas. LÄS MER
