  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. Identifying Piggybacking with Radar and Neural Networks

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Joel Sigurdsson; Hannes Olsson; [2022]
    Nyckelord :neural networks; classification; radar; access control; artificial; recurrent; convolutional; point clouds; cnn; ann; lstm; rnn; optimization; gradient descent; camera; piggybacking; tailgating; fmcw; pointnet; Mathematics and Statistics;

    Sammanfattning : A common problem in access control is piggybacking. This is when a person without authorized access sneaks closely behind another with access through a door. This thesis seeks to answer whether using radar is a viable solution when attempting to detect piggybacking. LÄS MER

  4. 3. Strategic passenger-oriented timetable design : Long-term timetable designs with minimised passenger inconvenience

    Master-uppsats, KTH/Transportplanering

    Författare :Yari de Graaf; [2021]
    Nyckelord :;

    Sammanfattning : Timetable development and design is a complex process that is crucial for safe and efficient railway operations. The combination of steel wheels and steel rails makes it possible to create trains and to transport many vehicles, thus passengers and freight, at the same time, but it also results in longer braking distances.

  5. 4. Energikartläggning av smältugnar i en aluminiumprocess : En analys av två oxyfuel-ugnars energiförbrukning, energiförluster och påverkande parametrar hos Gränges AB

    Kandidat-uppsats, Linköpings universitet/Mekanisk värmeteori och strömningslära

    Författare :Niclas Johansson; Philip Edman; [2021]
    Nyckelord :Oxy-fuel furnace; Reverberatory furnace; Secondary aluminium melting; Energy mapping; Energy consumption; Furnace door opening; Energikartläggning; Energianalys; Industriugn; Oxyfuel-ugn; Aluminiumsmältning; Omsmältverk; Parameterundersökning; Avgasförluster; Väggförluster; Askaförluster; Sumpförluster; Dörröppningsförluster;

    Sammanfattning : I denna rapport har ett projekt utförts tillsammans med Gränges AB. Projektet behandlade en energianalys av deras två oxyfuel-smältugnar för smältning av aluminium. Aluminiumsmältan består till stor del av återvunnet skrot, denna metod kallas omsmältning. LÄS MER

  7. 5. HfO2 and ITO Resistive Random-Access Memory

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

    Författare :Mattias Åstrand; [2020]
    Nyckelord :RRAM; Resistive switching; HfO2; ITO; Physics and Astronomy;

    Sammanfattning : The purpose of this work is of evaluating the choice of HfO2 and ITO as the dielectric and the top electrode in high performance resistive random-access memory (RRAM), respectively. The study is twofold, as it quantifies performance according to standard figures of merit for this technology, as well as provides insight into the physics of current conduction for this material choice.
