  1. 36. Predicting the Temporal Dynamics of Turbulent Channels through Deep Learning

    University essay from KTH/Strömningsmekanik och Teknisk Akustik

    Author : Borrelli Giuseppe; [2021]
    Keywords : Turbulent Flows; Deep Learning; Minimal Channel Flow; Fourier POD FFT-POD ; Data-driven analysis; Long-short-term-memory LSTM networks.;

    Abstract : The interest towrds machine learning applied to turbulence has experienced a fast-paced growth in the last years. Thanks to deep-learning algorithms, flow-control stratigies have been designed, as well as tools to model and reproduce the most relevant turbulent features. READ MORE

  3. 37. Eternal sunshine on the flower-spotted ground : Investigating diel rhythms during midnight sun on high-Arctic pollinators

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

    Author : Emma Limosa Djurberg; [2021]
    Keywords : High Arctic; Svalbard; Spitsbergen; insects; diel rythms; midnight sun; adaptation; foraging;

    Abstract : With over 600 articles about terrestrial invertebrates in Svalbard we still lack basic knowledge about pollinator-plant interactions in this part of the high-Arctic. It has never before been investigated how the activity of pollinators varies over a 24-hour timeframe in the high Arctic. READ MORE

  4. 38. Greenhouse gas emissions from three large lakes during the autumn 2020

    University essay from Linköpings universitet/Institutionen för tema

    Author : Veronica Bohlin; Anja Anderö Nordqvist; [2021]
    Keywords : methane; carbon dioxide; dissolved inorganic carbon; pCO2; flux chambers; large lakes; methane budget; carbon budget; GHGs; freshwater; spatiotemporal; ebullition; diffusion; autumn; metan; koldioxid; upplöst oorganiskt kol; pCO2; kammarmetod; stora sjöar; metanbudget; koldioxidbudget; växthusgaser; sötvatten; spatiotemporal; ebullition; diffusion; höst;

    Abstract : Methane (CH4) and carbon dioxide (CO2) are two greenhouse gases and main drivers of global climate change. Lakes are known to be a source of CH4 and CO2 to the atmosphere. While the importance of these emissions is clear, their magnitudes and regulation are still uncertain due to the scarcity of flux measurement data from lakes. READ MORE

  5. 39. Improving accessibility to the bus service : Building an accessibility measurement tool in QGIS

    University essay from Umeå universitet/Institutionen för geografi

    Author : Philip Lindén; [2021]
    Keywords : public transportation; public transit; fixed route transit systems; buses; bus stops; accessibility; measuring accessibility; measuring performance; social exclusion; vulnerable groups; GIS; QGIS; Graphical Modeler;

    Abstract : Satisfactory public transportation (PT) should enable people to reach attractive destinations and desired activities fast, comfortably, safely, and affordably. When PT fails to do so it will have negative effects on the overall accessibility in a society. READ MORE

  6. 40. Spatiotemporal Fidelity of a Metapopulational Model Evaluated on the COVID-19 Pandemic in Sweden

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Filip Skogh; [2021]
    Keywords : Epidemiology; COVID-19; Sweden; Metapopulation; SEIR; Model;

    Abstract : A modified SEIR compartmental model is constructed for COVID-19 in a metapopulational setting with fine-scaled population data. The model is stochastically simulated with GLEAMviz that provides realistic short and long distance mobility based on real-world data. READ MORE
