  1. 1. Nutrient flow on agroforestry farms in the province of Son La in northwest Vietnam

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Vindenergi

    Författare :Tula Strotz; [2023]
    Nyckelord :Agroforestry; contouring grass rows; Guinea grass; nutrient losses; Vietnam; Gräsbarriärer; Höglandsodling; näringsförlust; Träjordbruk; Vietnam;

    Sammanfattning : The population in the high mountains of the northwest provinces of Vietnam belongs to the poorest population in the country. Among the reasons behind this are the high frequency of minority groups in the region and the infertile soils of the steep slopes. LÄS MER

  3. 2. Experimental Study of Flow Fields in Moving Bed Biofilm Reactors

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

    Författare :Shea Nee Chew; [2023]
    Nyckelord :Moving bed biofilm reactors; Biofilm carriers; Mechanical mixing; Mixer configurations; Carrier mixing; Biofilmsreaktorer med rörlig bädd; Biofilmsbärare; Mekanisk blandning; Blandarkonfigurationer; Bärarblandning;

    Sammanfattning : With the rise in global energy prices, as well as energy consumption being the largest source of greenhouse gas emissions, biofilm-based systems utilized for wastewater treatment, such as moving bed biofilm reactors (MBBRs), have grown in popularity for their lower energy consumption compared to conventional activated sludge processes. However, this technology requires large amounts of energy to constantly distribute and suspend its biofilm carrier within the reactor by either aerators or mechanical mixers. LÄS MER

  4. 3. Digital Model of a Mining Stacker for Material Tracking : Modelling a Mining Stacker with Forward Kinematics for Material Tracking

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

    Författare :Livia Maria Waller; [2023]
    Nyckelord :Mining; Material tracking; Bucket wheel stacker; Gruvteknik; Materialspårning; Skovelhjulsstaplar;

    Sammanfattning : The Fourth Industrial Revolution is reshaping the manufacturing industry with the emergence of interconnectivity, smart automation, and cyber-physical systems. A popular example of cyber-physical systems is the digital twin or digital model, which both create a virtual (cyber) representation of a system. LÄS MER

  5. 4. Monitoring of heat exchanges in thesnowpack of Foxfonna glacier, Spitzbergen,Svalbard.

    Kandidat-uppsats, Lunds universitet/Förbränningsfysik; Lunds universitet/Fysiska institutionen

    Författare :Thibault Desjonquères; [2022]
    Nyckelord :Glaciers; Glaciology; Svalbard; Geophysics; Superimposed Ice; Foxfonna; Geology.; Physics and Astronomy;

    Sammanfattning : The processes of meltwater storage in firn and the impact of refreezing on firn-coveredglaciers have been investigated on the Greenland ice-sheet. On Svalbard, climate changepromotes the disappearance of firn on glaciers. LÄS MER

  7. 5. Holographic RG-flows and the Domain-Wall/Cosmology correspondence

    Master-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Jean-François Vaduret; [2022]
    Nyckelord :holography; cosmology; domain-wall; AdS; CFT; correspondence;

    Sammanfattning : In this master thesis we investigate implications of the Domain-Wall/Cosmology (DW/C) correspondence on one-point functions of holographic RG-flows. The thesis gives a detailed computation of linearized gauge-invariant Einstein equations in (d+1) dimensions while making the DW/C correspondence explicit. LÄS MER
