  1. 31. Development of an Investigation Method to Analyse Effect of Laser Cutting on Iron Losses in an Electric Machine

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

    Author : Rishabh Raj; [2022]
    Keywords : Electrical machine; iron losses; laser cutting; loss models; manufacturing defects; single sheet tester; Elektrisk maskin; järnförluster; laserskärning; förlustmodeller; tillverkningsfel; enplåtsprovare;

    Abstract : In this fast pace world, climate change is one of the primary concerns worldwide. The world is racing towards reducing CO2 emissions by focusing on decreasing energy consumption. Electric motors capture about two-third of the industrial energy consumption, of which the most growing sector is electrical vehicles. READ MORE

  3. 32. Developing biofertilisers in Grenada from the residues of an anaerobic digestion plant using Sargassum seaweed : Evaluating how problematic Sargassum algae can be turned in to a resource in Caribbean states

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Danielle Crowter Elfving; Emma Stahre; [2022]
    Keywords : Sargassum Algae; Fertiliser; Biofertiliser; Anaerobic Digestion; Massblooming; Cultivation; Sargassotång; Gödsel; Biogödsel; Anaerobisk Nedbrytning; Massblomning; Odling;

    Abstract : The West Indies have during recent years been experiencing large quantities of washed up Sargassum seaweed on beaches and coastlines causing many issues for local communities such as unpleasant odours, making beaches inaccessible and largely affecting tourism and fisheries. The issue has caused money loss for the communities both in cleaning costs and decreasing incomes from tourism and fishing. READ MORE

  4. 33. Analysis of degradation of melamine and polyurethane paint systems using different characterization methods. An investigation of automotive paints on trucks

    Keywords : Paint; degradation; analysis; melamine; polyurethane; Färg; nedbrytning; analys; melamin; polyuretan;

    Abstract : Sammanfattning på svenska: Billacker är exponerade för solljus och nederbörd under hela lackens livslängd. Lacker behöver motstå faktorer i omgivningen som påverkar nedbrytningen för att leva upp till högt ställda visuella krav. READ MORE

  5. 34. Increase of biogas production by incorporating residual streams from agriculture

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Stephanie Fjäll; [2022]
    Keywords : Anaerobic digestion; Agricultural residue; Lignocellulosic biomass; Mechanical pretreatment; Biogas production; Biorefinery; Chemical engineering; Agriculture and Food Sciences; Technology and Engineering;

    Abstract : To expand the biogas production in Region Västra Götaland (RVG), residual streams from the agricultural sector can function as a large-scale supplier of biomass. The production of biogas decreases the dependence of fossil fuels and the digestate that is formed can also be returned to the agricultural sector, creating a closed loop. READ MORE

  6. 35. Polymer-based additive manufacturing: optimization for high-performance degradable polymers

    University essay from KTH/Fiber- och polymerteknologi
