1. 21. Identifying Quaternary Climate Change with XRF Analysis on Loess From South-Western England

   Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Pelle Kronborg; [2020]
   Nyckelord :loess; XRF; weathering index; England; Lowland Point; Porth Cressa; Quaternary; löss; XRF; vittrings index; kvartär; England; Lowland Point; Porth Cressa;

   Sammanfattning : Huge changes in climate occurred at the end of the last Quaternary glaciation. The end of this glaciation corresponds with the end of Pleistocene with its repeated glacial cycles and the start of the current geological epoch, the Holocene interglacial. LÄS MER

3. 22. Forecasting anomalies in time series data from online production environments

   Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

   Författare :Raymond Sseguya; [2020]
   Nyckelord :Infor Sweden AB; time series forecasting; anomaly detection; ARIMA; neural network autoregression; eXtreme Gradient Boosting package;

   Sammanfattning : Anomaly detection on time series forecasts can be used by many industries in especially forewarning systems that can predict anomalies before they happen. Infor (Sweden) AB is software company that provides Enterprise Resource Planning cloud solutions. LÄS MER

4. 23. Arctic Loess as an Environmental Archive : Identifying Weathering with XRF Analysis in West Greenland

   Kandidat-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Isabelle Karnik; [2019]
   Nyckelord :loess; XRF; weathering index; Holocene climate; Greenland;

   Sammanfattning : Loess from west Greenland was studied to evaluate Holocene paleoclimate in the Arctic region. Deposits of loess are formed over long time scales through deposition of fine aeolian sediment and they exist in several places in the world. LÄS MER

5. 24. Aeolian and Pedogenic Processes of Loess in Southern England

   Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

   Författare :Ragna Orbe; [2019]
   Nyckelord :loess; Pegwell Bay; grain size distribution; magnetic susceptibility; past-climate reconstruction; lössavlagringar; Pegwell Bay; partikelstorleks distribution; magnetisk mottaglighet; historisk klimatrekonstruktion;

   Sammanfattning : Loess is an aeolian sediment that can be utilized as a detailed proxy of past climate, since it is one of few sediments that is deposited directly from the atmosphere on land. Investigation of loess deposits can give understanding of past regional and local wind circulation patterns and velocities, atmospheric dustiness, as well as paleo-precipitation and weathering conditions.

7. 25. Effects of MIFID II on Stock Trade Volumes of Nasdaq Stockholm

   Master-uppsats, KTH/Matematisk statistik

   Författare :Eva Elling; [2019]
   Nyckelord :TSCS; time series analysis; STL; ARIMA; causal inference; inference; treatment effect; Tidserieanalys; STL; ARIMA; inferens; causalitet; kausalitet; TSCS;

   Sammanfattning : Introducing new financial legislation to financial markets require caution to achieve the intended outcome. This thesis aims to investigate whether or not the newly installed revised Markets in Financial Instruments Directive- the MIFID II regulation - temporally influenced the trading stock volume levels of Nasdaq Stockholm during its introduction to the Swedish stock market.
