    Sammanfattning : Det är mycket dyrt att utveckla markinfrastruktur för att försörja hela jorden med internet. Detta ärspeciellt fallet i glesbebyggda områden då det finns lite ekonomisk vinning. Sverige som är ett stortoch glesbefolkat land har stora områden av denna typ. LÄS MER

  3. 2. Application of Fourier Transforms to time-resolved ambient pressure spectroscopy operando studies of CO oxidation over Pt(111)

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Synkrotronljusfysik

    Författare :Grigore-Leon Ratiu; [2024]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The study of heterogeneous catalysis has important implications in increasing the efficiency of industrial processes and in reducing the emissions of greenhouse gases from sources such as automobiles. A reaction with high industrial relevance is the oxidation of CO on noble metal catalysts. LÄS MER

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

    Master-uppsats, Uppsala universitet/Luft-, vatten- och landskapslära

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

    Sammanfattning : 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. LÄS MER

  5. 4. A quantitative study of Swedish high school L2 learners' receptive knowledge of English lexical collocations

    Kandidat-uppsats, Lunds universitet/Engelska

    Författare :Louise Frifelt; [2024]
    Nyckelord :Collocations; Multi-word units; Formulaic language; Second language acquisition; Languages and Literatures;

    Sammanfattning : This paper investigates receptive knowledge of English lexical collocations among Swedish high school students. The study tests the claim that L2 (second language) learners of English have a low level of collocational competence and tend to recognise high-frequent collocations more than low-frequent since the former have been encountered more.

  7. 5. Word Frequencies and Vocabulary Threshold Levels in EFL Textbooks. A Corpus Study

    Uppsats för yrkesexamina på avancerad nivå, Göteborgs universitet / Lärarutbildningsnämnden

    Författare :Samantha Read; [2023-06-19]
    Nyckelord :Vocabulary; corpus; coursebooks; upper secondary; word frequencies; threshold levels;

    Sammanfattning : A significant number of studies have identified inadequate vocabulary exposure in EFL coursebooks as a problem. However, few studies have been carried out in the Swedish context. LÄS MER
