  3. 2. Implications of different sensor resolutions and contrast settings in a roll-to-roll process, considering the speed of the process vs identifying defects, for manufacturing green batteries : A study on the effect of light conditions on thedetection of defects in cathode foil in batteries

    Master-uppsats, KTH/Mekatronik

    Författare :Behnam Yosef Nezhad Arya; [2021]
    Nyckelord :Contrast; Surface; Resolution; Speed; Defect; Sensor; Battery; Computer vision; Roll-to-roll; Contact Image Sensor; Mechatronics; Ljusinställning; Yta; Kontrast; Resolution; Hastighet; Defekt; skada; Sensor; Batteri; Computer vision; Roll-to-roll; Contact Image Sensor; Mekatronik.;

    Sammanfattning : This Master’s thesis work is about the conditions that can affect the identification of defects in lithium-ion batteries. In lithium batteries, there are cathode and anode, which are separated with electrically insulative but ionically conductive electrolytes and separators. LÄS MER

  4. 3. Problem Identification for Product Development Opportunities of Wine Refrigerators

    Master-uppsats, KTH/Energiteknik

    Författare :Malin Maria Erlandsson; Petra Näsström; [2018]
    Nyckelord :;

    Sammanfattning : Both value and flavor of wines can improve with time if stored properly. The factors with the most profound effect on the wine are light, humidity, temperature, vibrations, and ventilation. Light consisting of shorter wavelengths, under 450 nm, are dangerous for wine and can destroy the structure in wine. LÄS MER

  5. 4. Belastningsergonomi och arbetsmiljörisker vid maskinrumsarbete på fartyg : Riskbedömning av underhållsarbete på separatorer

    Uppsats för yrkesexamina på grundnivå, Linnéuniversitetet/Sjöfartshögskolan (SJÖ)

    Författare :Martin Bergkvist Bäcklin; Johan Johansson; [2015]
    Nyckelord :Risk assessment; KIM 1; ALBA; ergonomics; musculoskeletal disorders.; Riskbedömning; KIM1; ALBA; belastningsergonomi; belastningsbesvär.;

    Sammanfattning : Syftet med arbetet är att identifiera arbetsmiljörisker genom att analysera arbetsmomenten och arbetsmiljön vid en separatoröverhalning ombord ett fartyg. För att identifiera arbetsmiljörisker användes Arbetsmiljöverkets föreskrift AFS 2012:02, bedömningsmallen KIM 1 och programmet ALBA. LÄS MER

  7. 5. Measurement System to Monitor Interface Level Between Oil and Water in a Rapidly Rotating System

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)
