    Sammanfattning : I denna studie utvärderades skolplattformen Daisy, som används av studenter och anställda vid Stockholms universitet, institutionen för data- och systemvetenskap. Syftet med studien var att identifiera de allvarligaste användbarhetsproblem som studenterna upplevde samt hitta eventuella lösningar till problemen. LÄS MER

  2. 2. Using a GIS to enable an economic, land use and energy output comparison between small wind powered turbines and large-scale wind farms: the case of Oslo, Norway.

    Master-uppsats, Lunds universitet/Institutionen för naturgeografi och ekosystemvetenskap

    Författare :Colin Potter; [2023]
    Nyckelord :Geography; GIS; Wind power; Renewable energy sources; urban wind energy; urban areas; planning; vertical axis wind turbines; comparative studies; urban integrated energy systems; Oslo; Roan; Earth and Environmental Sciences;

    Sammanfattning : Responding to an identified knowledge gap, the study aims to determine if smaller wind turbines located on top of existing urban buildings are more resource efficient (land utilization and economically) than large scale wind farms. To answer this question, using a GIS, the resource efficiency of the Roan wind farm in Northern Norway was compared to a theoretical modeled installation of small-scale wind turbines on top of buildings within a 2km radius study zone in central Oslo.

  3. 3. Uncertainties in the use of synthetic CT (sCT) for daily online adaptive radiotherapy for lung cancer

    Master-uppsats, Lunds universitet/Sjukhusfysikerutbildningen

    Författare :Johansson Vivika; [2023]
    Nyckelord :Medicine and Health Sciences;

    Sammanfattning : Background and purpose: Cone Beam Computed Tomography (CBCT) based online adaptive radiotherapy (oART) has been clinically implemented for several anatomical sites worldwide. However, random and abrupt anatomical changes with large density alterations can occur in lung patients, leading to uncertainties with synthetic computed tomography (sCT) and dose calculation.

  4. 4. Comparison of graph databases and relational databases performance

    Kandidat-uppsats, Stockholms universitet/Institutionen för data- och systemvetenskap

    Författare :Einar Asplund; Johan Sandell; [2023]
    Nyckelord :Data Science; Graph database; Relational database; Performance; Benchmark; ANOVA; Computer and System Sciences;

    Sammanfattning : There has been a change of paradigm in which way information is being produced, processed, and consumed as a result of social media. While planning to store the data, it is important to choose a suitable database for the type of data, as unsuitable storage and analysis can have a noticeable impact on the system’s energy consumption.

  5. 5. eID in the e-learning Environment

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Zhe Pan; [2022]
    Nyckelord :e-learning; eID; cross-border; PEPS; test case; e-learning; eID; gränsöverskridande; PEPS; testfall;

    Sammanfattning : At present, there are different Electronic Identity (eID) systems utilized in EU, resulting in difficulties to carry eID information and transfer eID data of e-learning systems from one EU country to another. A project entitled Secure idenTity acrOss boRders linKed (STORK) was launched to address this problem, by installing a Pan European Proxy Service (PEPS) server. LÄS MER
