  1. 1. Ground validation and bias correction of GPM-IMERG V6 satellite precipitation product over Sweden

    Master-uppsats, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Mojtaba Moravej; [2020]
    Nyckelord :satellite precipitation product; bias correction; GPM-IMERG; Monte Carlo; evaluation; rain; Earth and Environmental Sciences;

    Sammanfattning : This study attempts to assess and correct the performance of Integrated Multi-satellite Retrievals for Global Precipitation Measurement (GPM-IMERG) final run daily precipitation product across Sweden. The performance of GPM-IMERG version 6 final run was evaluated against 677 rain gauges in a period from 12 March 2014 to 31 May 2019. LÄS MER

  3. 2. Höjdmätning av träd med olika drönarsystem

    Kandidat-uppsats, SLU/Dept. of Forest Ecology and Management

    Författare :August Nilsson; [2018]
    Nyckelord :SfM; UAV; fjärranalys; punktmoln; skog;

    Sammanfattning : Syftet med den här studien var att undersöka höjdmätning av träd med olika drönarsystem genom att använda metoden structure from motion (SfM). Detta gjordes för att se om det fanns skillnader mellan drönarsystemen i höjdmätningens noggrannhet och andel markyta som registrerats, samt om höjdmätningens resultat blev tillräckligt noggrant för att det skulle kunna användas praktiskt inom skogsbruket.

  4. 3. An evaluation of using GPM satellite products to forecast flash floods in mountainous catchments

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Avdelningen för Teknisk vattenresurslära

    Författare :Yihan Chen; [2017]
    Nyckelord :GPM; Han River; Flood; IMERG; Mountain; Technology and Engineering;

    Sammanfattning : NASA's GPM satellite rainfall products IMERG early run and IMERG late run were evaluated for their applicability in flash flood forecasting. The selected catchment was the upper Han River basin, a mountainous catchment with low precipitation in winter and heavy precipitation during summers located in central China. LÄS MER

  5. 4. Valuation Accuracy of the RIV Model - Is it possible to improve the valuation accuracy of the RIV model when taking both conservative measurement bias and business goodwill/badwill into account?

    D-uppsats, Handelshögskolan i Stockholm/Institutionen för redovisning och finansiering

    Författare :Alexander Norrman; Jenny Rahmn; [2016]
    Nyckelord :Equity valuation; Residual income; Conservative accounting; Valuation accuracy;

    Sammanfattning : The residual income valuation model (RIV) presented by Ohlson (1995) relies on unbiased accounting. The presence of conservative accounting, however, has been well recognized within research (e.g. Mora and Walker, 2015; Barker, 2015). LÄS MER

  7. 5. QUANTIFYING THE BIASED EXCHANGE OF MONEY AND TIME - How monetary and social factors influence decisions

    Kandidat-uppsats, Lunds universitet/Institutionen för psykologi

    Författare :Kristoffer Bergram; Karan Luthra; [2016]
    Nyckelord :behavioural economics; decision-making; consumer psychology; prospect theory; anchoring effect; contrast effect; construal level theory. social distance; relative bias measurement; decision congruency; Social Sciences; Business and Economics;

    Sammanfattning : This study investigated whether anchored prices induced biased choices and time estimations for the pursuit of an equal discount and if different degrees of social distance influenced these biases. A new measurement for quantifying the relative degree of bias was also proposed. LÄS MER
