  1. 21. Design and Optimization of Ultrafiltration Membrane Setup for Wastewater Treatment and Reuse

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

    Författare :Ekansh Sharma; [2020]
    Nyckelord :parameters; membrane; predict; optimize; quality; reduction;

    Sammanfattning : With the advances in the membrane technology, there is an ongoing quest to determine the best optimal configuration for an adopted treatment as well as it’s polishing to achieve cumulative sustainability for the treatment process. Henceforth, this thesis report is an evaluation to devise a membrane filtration process for investigating the possibility of treating pre-sedimented municipal wastewater with ceramic ultrafiltration, optimizing the membrane as a pre-treatment for reverse osmosis as an overall strategy for recovering wastewater.

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

    Författare :Alexander Bergman; Mire Persmark; [2020]
    Nyckelord :Rainwater Infiltration; Alluvial Plain; Chocaya Basin; Hydraulic Conductivity; Double Ring Infiltrometer DRI ; Hydrus-1D; Electrical Resistivity Tomography ERT ; Earth and Environmental Sciences;

    Sammanfattning : The objective of this study was to assess the rainwater infiltration process in the unsaturated zone in an alluvial plain. Particularly, this study is focused on the Chocaya basin in central Bolivia. LÄS MER

  4. 23. INTERMEDIATE-SCALE TESTS AND CONE CALORIMETER TESTS - FIRE BEHAVIOUR OF SELECTED FACADE MATERIALS

    Master-uppsats, Lunds universitet/Avdelningen för Brandteknik

    Författare :Tanja Cernosa; [2020]
    Nyckelord :Fire behaviour; Intermediate-scale facade tests; cone calorimeter; stone wool; phenolic foam; WRB; Technology and Engineering;

    Sammanfattning : In the last few years, the implementation of well-ventilated façades in buildings increased due to their improved energy performance. However, their double-wall construction due to the limited airflow within an air cavity represents a significant fire risk, since the flames that spread into the air cavity can elongate up to ten times.

  5. 24. Dark Matter – Direct Detection and Capture in the Sun

    Master-uppsats, KTH/Fysik

    Författare :Erika Lind; [2020]
    Nyckelord :Dark matter; direct detection; indirect detection; solar capture; inelastic dark matter; Mörk materia; direkt detektion; indirekt detektion; solinfångning; inelastisk mörk materia;

    Sammanfattning : Dark matter has been inferred from various observations such as in galaxy clusters, flat galactic rotation curves, gravitational lensing measurements and the cosmic microwave background. Despite overwhelming observational evidence and ongoing searches, a clear signal of dark matter has not yet been detected. LÄS MER

  7. 25. Modelling and Control of a Dual Sided Linear Induction Motor for a scaled Hyperloop Pod

    Master-uppsats, KTH/Fordonsdynamik

    Författare :Vivek Anand; [2020]
    Nyckelord :Linear Induction Motor; Rotary Induction Motor; Control algorithm; bandwidth; Synchronous frame; Field weakening; Inductance; Resistance; PI controller; Magnetic flux; Mutual Inductance; Rise time; Roterande induktionsmotor; styralgorithm; bandbredd; synkron ram; induktans; moststånd; PI-regulator; magnetiskt flöde; ömsesidig induktans; stingningstid; fel; Linjär induktionsmotor;

    Sammanfattning : The electrification era has been marked up by an increase in volume of electric vehicles which are directly or indirectly powered by electricity. Railways, roadways and airways are being electrified as we speak at their own respective rate. LÄS MER
