  1. 1. Real-time Sound Analysis to Count Opening Cycles of Automatic Doors

    Master-uppsats, Lunds universitet/Institutionen för elektro- och informationsteknik

    Författare :Teodor Renman; Charlie Ringström; [2023]
    Nyckelord :Sound analysis; signal processing; event detection; MFCC; real-time; automatic door; embedded programming; stm32; microcontroller; Technology and Engineering;

    Sammanfattning : Counting opening cycles on an automatic sliding door is of great interest for a company manufacturing doors, such as ASSA Abloy. These metrics could be used for consumer statistics or for door diagnostics. Counting opening cycles is seemingly trivial when there is access to the door’s internal diagnostics or having adequate sensors. LÄS MER

  3. 2. Towards low carbon buildings: A case study in Sweden

    Master-uppsats, Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Författare :Huynh Tuan Tran; Victor-Antoine Delorme; [2023]
    Nyckelord :Life cycle assessment; Environmental impact of building materials; Carbon neutrality; Biobased material; Biochar; Cross Laminated Timber; Biogenic carbon; Earth and Environmental Sciences; Technology and Engineering;

    Sammanfattning : This study comprehensively evaluated the global warming potential of an office building in a newly built Scandinavian neighbourhood seeking to reach sustainability. The primary objective of the research was to support the city authorities of Helsingborg by providing valuable insights into actual carbon emissions at the building level and proposing measures to minimize these emissions to achieve climate neutrality by 2030.

  4. 3. Lithium-ion battery modeling and SoC estimation

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

    Författare :Ruoyu Xu; [2023]
    Nyckelord :lithium-ion battery; cell modeling; state of charge; extended Kalman filter; pack modeling; litiumjonbatteri; cellmodellering; laddningstillstånd; utökat Kalmanfilter; packmodellering;

    Sammanfattning : The energy crisis and environmental pollution have become increasingly prominent in recent years. Lithium batteries have attracted extensive attention due to their high energy density, safety, and low pollution. To further study how the battery works, it is necessary to establish an accurate model conforming to the battery characteristics. LÄS MER

  5. 4. Cracking and Fatigue in the Prestressed Concrete Bridge at Autio

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Byggkonstruktion och brand

    Författare :Kasper Andersson; Jon Leidzén; [2022]
    Nyckelord :Fatigue; Cracking; Prestressed Concrete Bridge; Rainflow;

    Sammanfattning : In early 2020, cracks were discovered on the bridge crossing the Torne River at Autio. This resulted in an investigation being launched to determine the structural state of the bridge. LÄS MER

  7. 5. Transformation of In-Flight Measured Loads to a Fatigue Test Spectrum

    Master-uppsats, Linköpings universitet/Mekanik och hållfasthetslära

    Författare :Patrick Dümig; [2022]
    Nyckelord :Aerospace engineering; Aircraft load spectra; ASIP; Crack growth; Fatigue testing; Flight loads; Flight test; Fracture mechanics; FSFT; In-flight measurements; Load spectrum reduction; Racetrack filtering; Strain gauge measurements;

    Sammanfattning : Fatigue is a well-recognized issue in lightweight and high-performance aircraft structures. As fatigue failures have led to serious accidents and caused significant economic impact in the past, design against fatigue is crucial. LÄS MER
