  1. 1. Åtgärder mot förhöjda halter av per- och polyfluorerade alkylsubstanser (PFAS) i dagvatten : Styrande mål och riktvärden

    Uppsats för yrkesexamina på avancerad nivå,

    Författare :Felicia Hagberg; [2024]
    Nyckelord :PFAS; PFCA; PFSA; stormwater; guidelines; foam fractionation; activated carbon; anion exchangers; PFAS; PFCA; PFSA; dagvatten; riktvärden; åtgärder; skumfraktionering; aktivt kol; jonbytare;

    Sammanfattning : Stormwater is a significant transport medium for pollutants to recipients located near cities. Substances commonly found in stormwater include nutrients, metals, organic substances and particles. A group of pollutants detected in stormwater are per- och polyfluoroalkyl substances (PFAS).

  3. 2. Microstructures and Compressive Strength of Lake Ice in Sweden A structural Documentation and Compressive Strength Analysis of Lake Ice Cores from Uppsala, using the SonReb Method

    Master-uppsats, Göteborgs universitet/Institutionen för geovetenskaper

    Författare :Julia Ladefoged; [2023-08-18]
    Nyckelord :;

    Sammanfattning : Lake ice have been utilized by humans through centuries, as transportation routes and recreational activities to name a few (Sharma et al., 2019). Despite our frequent usage of lake ice there is a lack of extensive knowledge of it. LÄS MER

  4. 3. Image-driven simulation of brain tumors using a reaction-diffusion mathematical model

    Master-uppsats, Linköpings universitet/Avdelningen för medicinsk teknik

    Författare :Kristos Qiqi; [2023]
    Nyckelord :brain tumor; cancer; mathematical model; simulation; magnetic resonance images; hjärntumör; cancer; matematisk model; simulering; magnetresonanstomografi bilder;

    Sammanfattning : Brain tumors pose a big challenge in the field of neuro-oncology. Gliomas are the largest subgroup. Magnetic resonance imaging is a non-invasive tool for detecting and characterizing these tumors. Mathematical models, such as the reaction-diffusion equation, can be used for understanding the intricate behavior of gliomas. LÄS MER

  5. 4. Development of a cable analysis theory based on integral equation derivation

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Sandra Larsson; [2023]
    Nyckelord :;

    Sammanfattning : Electrification of transportation is a major subject of research today, especially in air travel. The increasing number of electronics and cables also increases the interference between them. From this, interest grew to increase the accuracy of electromagnetic modeling of cables. LÄS MER

  7. 5. Stock market analysis with a Markovian approach: Properties and prediction of OMXS30

    Kandidat-uppsats, KTH/Matematisk statistik

    Författare :Max Aronsson; Anna Folkesson; [2023]
    Nyckelord :Markov chain; OMXS30; Markov chain properties; voting ensemble model; markovkedja; OMXS30; egenskaper hos markovkedjor; ensemble-modell;

    Sammanfattning : This paper investigates how Markov chain modelling can be applied to the Swedish stock index OMXS30. The investigation is two-fold. Firstly, a Markov chain is based on index data from recent years, where properties such as transition matrix, stationary distribution and hitting time are studied. LÄS MER
