  1. 1. Skattning av HGV och stamvolym med data från stereomatchade drönarbilder genom befintliga modeller från Skogliga grunddata

    University essay from SLU/Dept. of Forest Resource Management

    Author : Erik Forslöw; [2023]
    Keywords : drönare; stereofotogrammetri; skogliga grunddata; skogsbruksplanläggning;

    Abstract : Inom den svenska skogsbruksplanläggningen sker idag datainsamlingen traditionellt med subjektivt fördelade relaskopsytor. Den subjektiva mätningen varierar mellan och inom planläggare och har generellt ett relativt medelfel (rRMSE) på 9 % för grundytevägd medelhöjd (HGV) och 15–20 % for volym/ha. READ MORE

  3. 2. Prediction of Reverberation Time in Office Spaces by Investigation of the Scattering Factor in Odeon

    University essay from KTH/Teknisk akustik

    Author : Viktor Söderlund; [2023]
    Keywords : Scattering Factor; Reverberation Time; Odeon; Sabine; Arau-Puchades; Spridningsfaktor; Efterklangstid; Odeon; Sabine; Arau-Puchades;

    Abstract : Accurate estimations of the reverberation time of furnished office spacesis essential as an acoustic consultant. A time efficient way to predict thefurniture’s effect is to investigate it by software modelling. The room acousticsoftware Odeon is suitable for doing this. READ MORE

  4. 3. Tracking Optimization in Agrivoltaic Systems : A Comparative Study for Apple Orchards

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Maddalena Bruno; [2023]
    Keywords : Agrivoltaics; Optimization; Light sharing; Apple Orchards; Lantbruk; Optimering; Ljusdelning; Äppelodlingar;

    Abstract : Agrivoltaic (APV) systems, based on the co-location of solar panels and crops, are an innovative solution to land-use conflicts that often arise between agriculture and energy production. Their optimal functioning starts with efficient management and sharing of light between solar panels and underlying plants. READ MORE

  5. 4. Review and Design of DC Electrical Field Measurement Systems and Related Developments : For Measurements Around HVDC Cable Terminations

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Emil Bergvall; [2023]
    Keywords : DC Field Probe; Measurement Systems; Electric Fields; Cable Termination; Ion Drift; Conductivity; HVDC; Field Mill; Field Simulations; Positioning System; MEMS; Electro-Optics; DC Fält Prob; Mätsystem; Elektriska Fält; Kabelavslut; Jondrift; Ledningsförmåga; HVDC; Fältkvarn; Fält Simulationer; Positioneringsystem; MEMS; Elektro-Optik;

    Abstract : With power generation and consumption placed further away from each other, with for example increased offshore power production, the need for HVDC transmission systems increases. As voltage levels in the HVDC transmission system are raised, the losses can be decreased, enabling efficient power transfer over longer distances. READ MORE

  6. 5. Characterization of Landscape Structures and Precipitation in relation to Flooding events in Pampa Deprimida : A Minor Field Study in Argentina

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

    Author : Linnea Svärd; [2023]
    Keywords : Pampeana hydrology; flood risk mapping; runoff; infiltration; precipitation; SCSCN; remote sensingg; Hydrologi på Pampas; kartläggning av översvämningsrisker; avrinning; infiltration; nederbörd; SCS-CN; fjärranalys; Hidrología de la Pampa Deprimida; cartografía del riesgo de inundaciones; escorrentía; infiltración; precipitación; SCS-CN; sensores remotos;

    Abstract : The purpose of the thesis is to characterize flood events within the agricultural fields of flooding Pampa in Argentina. The characterization divides the flat landscape into flood prone areas and endeavour at linking driving factors to flood response based on past events. READ MORE
