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

    University essay from Lunds universitet/Institutionen för elektro- och informationsteknik

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

    Abstract : 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. READ MORE

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

    University essay from Lunds universitet/Avdelningen för Energi och byggnadsdesign; Lunds universitet/Institutionen för arkitektur och byggd miljö

    Author : Huynh Tuan Tran; Victor-Antoine Delorme; [2023]
    Keywords : 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;

    Abstract : 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.
