  1. 11. Integration of Open Data in Disaggregate Transport Modelling : A Case Study of Uppsala

    Master-uppsats, KTH/Transportplanering

    Författare :Iqbal Surahman; Gustav Wegner; [2022]
    Nyckelord :Agent-based; Disaggregate Transport Model; Open Data; OpenStreetMap; OSM; GTFS; Agentbaserad; Disaggregerad Transportmodell; OpenData; OpenStreetMap; OSM; GTFS;

    Sammanfattning : Transport models are key in predicting travel behaviour and planning transport systems. Transport models can be either aggregated or disaggregated. Disaggregation means that travel behaviour is represented on an individual level, which can be beneficial because it offers a higher detail level and reduces aggregation bias. LÄS MER

  3. 12. Long-term Effect of Metallic Iron Sorbents on Arsenic Mobility in an Anoxic Aquifer : An assessment based on long-term column experiments

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Stéphanie Nyström; [2022]
    Nyckelord :Zero valent iron; ZVI; Remediation; Anoxic; Column tests; ICP-MS;

    Sammanfattning : Zero valent iron (ZVI) sorbents have successfully remediated soils burdened with different groups of contaminants. When working to alleviate arsenic (As) contamination, the location-specific subsurface chemistry greatly affects the efficiency of the sorbents as it controls the speciation of As and the transformation of the ZVI, as well as the interaction between these (remediating mechanisms).

  4. 13. Water quality and organic matter linkages in waters draining arable fields

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Adam Eriksson; [2021]
    Nyckelord :Natural organic matter NOM ; particular organic matter POM ; dissolved organic matter DOM ; allochthonous; autochthonous; Florescence index FIX ; Freshness index BIX ; Humification index HIX ; SUVA 254; E2:E3; Spectral Slope; Observation fields; microbial matter; humic matter; unfiltered samples UF ; filtered samples F45 ;

    Sammanfattning : This study investigated leaching of natural organic matter (NOM) in twelve Swedish arable fields with regards to the quality of dissolved organic matter (DOM) and particulate organic matter (POM), using Absorbance (UV-Vis) and fluorescence spectrometry (EEM). DOM is defined as organic matter (OM) 0.45 μm. LÄS MER

  5. 14. Comparison of state-of-the-art Temporal Interaction Network methods in different settings : Novel models to predict temporal behavior

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

    Författare :Indre Tauroseviciute; [2021]
    Nyckelord :Recommendation systems; Neural Collaborative Filtering; RNN; Backpropagation; Comparative analysis;

    Sammanfattning : Recommendation systems become more and more necessary due to the growing supply chain. Therefore, scientists are developing models that can serve different recommendation needs faster than before, and it is getting more complicated to choose the model for a specific case. LÄS MER

  7. 15. A Real- time Log Correlation System for Security Information and Event Management

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

    Författare :Clémence Dubuc; [2021]
    Nyckelord :Correlation; SIEM; Security Logs; Apache Spark; Elastic Search; Korrelation; SIEM; Säkerhetsloggar; Apache Spark; Elastic Search;

    Sammanfattning : The correlation of several events in a period of time is a necessity for a threat detection platform. In the case of multistep attacks (attacks characterized by a sequence of executed commands), it allows detecting the different steps one by one and correlating them to raise an alert. LÄS MER
