  1. 1. The Role of Uni- and Multivariate Bias Adjustment Methods for Future Hydrological Projections and Subsequent Decision-Making

    University essay from Uppsala universitet/Luft-, vatten- och landskapslära

    Author : Anna Merle Liebenehm-Axmann; [2024]
    Keywords : Bias adjustment methods; future hydrological climate projections; statistical analysis; future streamflow analysis; biasjusteringsmetoder; framtida hydrologiska projektioner; statistisk analys; framtida vattenförings analys;

    Abstract : Climate models are essential for generating future climate projections. However, due to simplifications, the models can produce systematic differences between output and reality, which is referred to as model bias. Bias adjustment methods aim to reduce this error, which is important for making future projections more reliable. READ MORE

    Keywords : Formal Methods; Statistical Model-Checking; Timed Automata; Timed PetriNets; Formella Metoder; Statistisk Modellkontroll; Timed Automater; Time Petri Nets;

    Abstract : With the prevalence of technology and computer systems in today’s society, it is crucial to ensure that the systems we use are secure. The fields that study these issues, cybersecurity and cybersafety, use the formal verification technique of modelchecking. READ MORE

  5. 4. Predicting the Impact of Supply Chain Disruptions Using Statistical Analysis and Machine Learning

    University essay from KTH/Matematisk statistik

    Author : Hannes Andersson; John Sjöberg; [2023]
    Keywords : Supply chain disruption; SMOTE; feature engineering; machine learning; random forest; statistics; applied mathematics; Störning i försörjningskedja; maskininlärning; matematik; statistik;

    Abstract : The dairy business is vulnerable to supply chain disruptions since large safety stocks to cover up losses are not always a viable option, therefore it is crucial to maintain a smooth supply chain to ensure stable delivery accuracies. Disruptions are unpredictable and hard to avoid in the supply chain, especially in cases where production errors cause lost production volume. READ MORE

  6. 5. A Statistical Approach to Understand the Evolution of Exotic Butterfly Species

    University essay from KTH/Matematisk statistik

    Author : Elin Eliasson; Rebecka Haraldsson; [2023]
    Keywords : Phylogenetics; Tree reconstruction; COI barcoding; General Time Reversible Model; K80 Model; Evolution; Butterflies; Fylogenetik; Rekonstruktion av träd; COI barcoding; General Time Reversible modell; K80 modell; Evolution; Fjärilar;

    Abstract : The alarming rate at which we see the decline in biodiversity due to human activity has raised concerns about the well-being of our planet. Butterflies which serve as pollinators are an essential part of many ecosystems and sensitive indicators of environmental changes and can provide valuable insight into how ecosystems function and evolve.
