  1. 1. The active phase of Pt(110) during catalytic CO oxidation

    Master-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Hira Qazilbash; [2024]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : CO oxidation is an important topic in heterogeneous catalysis, due to its role in industrial processes such as pollution reduction in the auto industry, and ethanol or other fuel production. In the automotive catalytic converters CO oxidation reduces the poisonous CO to CO2 by reacting with O2. LÄS MER

  3. 2. Effektivisering och flödeskartläggning : En jämförelse av arbetsflöden i ett industriserviceföretag

    Kandidat-uppsats, Högskolan i Gävle/Avdelningen för industriell ekonomi, industridesign och maskinteknik

    Författare :Jesper Andersson; Max Englund; [2023]
    Nyckelord :Flödeskartläggning; value stream mapping; ledtid; lean; 5s; just in time;

    Sammanfattning : Introduction: To stay relevant, it is required that companies work with continuous improvements.Finding inefficiencies is not always easy. One way to try to find inefficiencies is throughflow mapping. This study examines what causes inefficient activities for industrial servicecompanies. LÄS MER

  4. 3. Audibility & Preference of DA Overload Associated with True Peak : Investigation of claims made against overload prevention

    Kandidat-uppsats, Luleå tekniska universitet/Musik, medier och teater

    Författare :Mattias Strand; [2023]
    Nyckelord :true peak; mastering; inter-sample; intersample; peaks; peaking; overload; digital to analog; da; loudness; clipping; truncation; square wave;

    Sammanfattning : The conversion of audio from the digital to analog domain has the potential to result in distortion due to converter overload. This occurs because some peaks in the signal cannot be defined digitally and only become problematic during the conversion into the analog domain, exceeding the level that can be represented by the converter, causing it to overload.

  5. 4. Utvärdering av förebyggande underhållsstrategi för elektriska flygplan

    M1-uppsats, Mälardalens universitet/Akademin för innovation, design och teknik

    Författare :Ammar Alfredsson; [2023]
    Nyckelord :Elektriska flygplan; Förebyggande underhåll; Batterier; Elmotor; Drivlinor; Hybrid; Smarta system;

    Sammanfattning : This thesis focuses on the topic of preventive maintenance for electric aircraft and aims to examine its significance and implementation within the aviation industry. Electric aircraft have become increasingly popular as a sustainable alternative to conventional aircraft, making it crucial to develop effective maintenance strategies to ensure their reliability and performance.

  7. 5. Development and Analysis of Small Signal DQ-Frame Model for Low Frequency Stability of Train Converters

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

    Författare :Fabian Tidner; [2023]
    Nyckelord :Low Frequency stability; DQ-frame modeling; Single phase converter; Electric rail way systems; Lågfrekvent stabilitet; DQ-ram modellering; Enfasig likriktare; Elektriska järnvägssystem;

    Sammanfattning : In order to meet the increasing demand for sustainable transportation, trains need to run with tighter schedules, more departures and more trains in depot. Multiple trains in depot has been linked to low frequency instability at many locations around the world. LÄS MER
