  1. 1. Simulating Mobility of Large Population using Mobile Application Data

    Master-uppsats, Göteborgs universitet/Institutionen för data- och informationsteknik

    Författare :Mattias Rydström; Diana Salim; [2024-01-23]
    Nyckelord :Human mobility; mobile application data; synthesize activity plans;

    Sammanfattning : Understanding people’s travel patterns and knowing the frequency of their travel activities provide important insights for effective transport management and infrastructure planning. While traditional travel surveys have historically contributed to this valuable information, they come with shortcomings such as being expensive to collect, easily outdated, and having short time coverage.

    Sammanfattning : The Covid-19 pandemic presented unprecedented challenges, with global lockdowns impacting individuals on a profound scale. Many took to social media to cope with feelings of anxiety and isolation. LÄS MER

  4. 3. CFD-simulering av värmeöverföring under upptändningsförlopp av krutraketmotor

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Carl-Otto Olsson Sjögren; [2024]
    Nyckelord :Computational Fluid Dynamics; CFD; Anfyrning; upptändning; CFD; strömningslära; värmeöverföring; termisk strålning; krutraketmotor; konvektion;

    Sammanfattning : SAAB Dynamics producerar och utvecklar flertalet produkter som innehåller krutraketmotorer. Krutraketmotorers prestanda är kraftigt beroende av en effektiv upptändning och det är önskvärt att kunna prediktera detta förlopp numeriskt med god noggrannhet. Ingen etablerad simuleringsmetodik existerar i dagsläget. LÄS MER

  5. 4. Evaluating the accuracy of NEWA, ERA5 and NORA3 in predicting onshore wind conditions: a comparative study using ICOS meteorological mast data in Sweden

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Svetlana Kuru; [2024]
    Nyckelord :NEWA; ERA5; NORA3; wind speed; wind distribution; correlation coefficient;

    Sammanfattning : The ECMWF Reanalysis v5 (ERA5), the New European Wind Atlas (NEWA), and the 3 km Norwegian Reanalysis (NORA3) are reference datasets that are available for industry and research. The resolution of 3km in both the NORA3 and NEWA datasets sets them apart, while ERA5, with its 31km resolution, continues to serve as a reliable data source that is widely used in the industry.

  7. 5. Diving Deep: Seabird foraging tactics and local prey field

    Master-uppsats, SLU/Dept. Of Aquatic Resources

    Författare :Elin Andersson Sjöholm; [2024]
    Nyckelord :Common Guillemot; Uria aalge; Optimal Foraging theory; Hydroacoustic data; resource selection;

    Sammanfattning : Foragers in patchy environments need to decide what patches to use and how to allocate their time between them. Optimal foraging theory describes these choices through the relationship between energy expenditure and energy gain. LÄS MER
