  1. 21. Scaling Apache Hudi by boosting query performance with RonDB as a Global Index : Adopting a LATS data store for indexing

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

    Författare :Ralfs Zangis; [2022]
    Nyckelord :Apache Hudi; Lakehouse; RonDB; Performance; Index; Key-value store; Apache Hudi; Lakehouse; RonDB; Prestanda; Index; Nyckel-värde butik;

    Sammanfattning : The storage and use of voluminous data are perplexing issues, the resolution of which has become more pressing with the exponential growth of information. Lakehouses are relatively new approaches that try to accomplish this while hiding the complexity from the user. LÄS MER

  3. 22. Inverse Uncertainty Quantification for Sounding Rocket Dispersion

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Tove Ågren; [2022]
    Nyckelord :Uncertainty quantification; Bayesian inference; Rocket dispersion; Neural networks; Markov Chain Monte Carlo.; Osäkerhetskvantifiering; Bayesiansk inferens; Raketspridning; Neurala nätverk; Markovkedje-Monte Carlo;

    Sammanfattning : Sounding rocket impact points are subject to dispersion due to uncertainties in simulation model parameters and perturbations of the rocket trajectory during flight. Estimating the area of dispersion assumes that associated model uncertainties and magnitude of perturbations have already been inferred. LÄS MER

  4. 23. Data-driven Discovery of Real-time Road Compaction Parameters

    Master-uppsats, KTH/Matematisk statistik

    Författare :Yuqi Shao; [2022]
    Nyckelord :statistics; machine learning; road compaction; statistik; maskininlärning; vägpackning;

    Sammanfattning : Road compaction is the last and important stage in road construction. Both under-compaction and over-compaction are inappropriate and may lead to road failures. Intelligent compactors has enabled data gathering and edge computing functionalities, which introduces possibilities in data-driven compaction control. LÄS MER

  5. 24. Fysikstudenters minnen av fysiklaborationer

    Uppsats för yrkesexamina på grundnivå, Uppsala universitet/Fysikundervisningens didaktik

    Författare :Gustav Linnarsson; [2022]
    Nyckelord :Fysik; minne; didaktik;

    Sammanfattning : Laborationer är en metod som endast existerar inom skolan vars syfte är att befästa teori och hur man genomför experiment. Inom svensk gymnasiefysik ska elever lära sig planera, genomföra, tolka och redovisa experiment och observationer. LÄS MER

  7. 25. Extraction efficiency of four pesticides using the QuEChERS extraction method and analysis by HPLC/DAD

    Kandidat-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Honia Rasul; [2022]
    Nyckelord :analytical chemistry; pesticides; QuEChERS; soil; Chemistry;

    Sammanfattning : A cleanup step is essential from an analytical perspective, to improve the chance of quantification and to minimize interference. Pesticides in soil are a necessity is agriculture for survival of crops and protection from unwanted growth and pests. LÄS MER
