  1. 21. Flow pattern analysis of a Surface Flow Constructed Wetland : Treating surface runoff and landfill leachate water from the Löt waste management site

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Max-Bernhard Alm; [2020]
    Nyckelord :Surface flow constructed wetland; flow pattern analysis; numerical model;

    Sammanfattning : The waste management and recycling company, Söderhalls Renhållningsverk (SÖRAB) have constructed a surface flow wetland in order to treat surface runoff from the waste management site, Löt. The contaminated water passes several treatment steps until it reaches the wetland and a subsequent soil infiltration step. LÄS MER

  3. 22. Internal charging modelling of the AMBER instrument on-board Jason-3 spacecraft

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Jeremie Hacquart; [2020]
    Nyckelord :Internal Charging; Satellite; Plasma; SPIS; Intern laddning; satellit; plasma; SPIS;

    Sammanfattning : Internal charging is the accumulation of charged particles inside a material. Thisbuild up represents a serious hazard to satellites and instruments exposed to thespace environment. The Van Allen radiation belts constitute one of the worst spaceenvironments for satellites orbiting the earth. LÄS MER

  4. 23. Praktisk modellering av vitvatten i den turbulenta vaken för jämförelse av marina propulsorer

    Master-uppsats, KTH/Marina system

    Författare :Felix Brodin; [2020]
    Nyckelord :;

    Sammanfattning : En semi-empirisk modell som beskriver vitvattets sönderfall i den turbulenta vaken har härletts utifrån optiska studier av Stridsbåt 90H och Buster Magnum. Bakgrunden är ett ökat hot från rymdburna system mot den svenska Marinen. Fokus har varit Amfibiekårens båtpark. LÄS MER

  5. 24. Review of Observation and SystemIdentification Techniques in a VerifiedModel of a Satellite with Flexible Panels

    Master-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Aydin Nakhaeezadeh Gutierrez; [2020]
    Nyckelord :Satellite Modelling; flexible appendices; Structure Monitoring; System Identification; N4SID; DUKF;

    Sammanfattning : The demand of space applications has been increasing over the years. This has derivedin new satellites structures that required from precise and robust control management.The satellite design is evolving towards the development of lighter structures. LÄS MER

  7. 25. Modelling of the thermal environment and subsystem for a 6U cubesat in GTO orbit

    Magister-uppsats, Luleå tekniska universitet/Rymdteknik

    Författare :Vidhyuth Kasturi Chakravarthy Iyengar; [2020]
    Nyckelord :;

    Sammanfattning : The thermal design of the spacecraft ensures the unobstructed and smoothoperation of the spacecraft under the harsh space conditions. As small satellitesare getting more accessible and standardized, their uses are growing more intomission scenarios which are conventionally used by larger satellites. LÄS MER
