  1. 1. Solutions for presence detection in an intercom door station

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Industriell elektroteknik och automation

    Författare :Anton Bengtsson; Måns Andreasson; [2023]
    Nyckelord :presence detection; sensor technology; PIR; ultrasonic; radar; intercom; Technology and Engineering;

    Sammanfattning : In this work, different solutions for human presence detection in a door intercom device are examined. The study was conducted at a company in Lund, Sweden. LÄS MER

  3. 2. Waiting for the Magic Bus: Unravelling the Impact of Bus Design on Station Dwell Time : A Comprehensive Analysis and Case Study

    Master-uppsats, KTH/Transportplanering

    Författare :Efrat Aviad; [2023]
    Nyckelord :;

    Sammanfattning : With the continuous decrease in average speed in cities, public transport operators need to think of new ways to improve operation efficiency and shorten total trip durations. This thesis investigates how bus design aspects, like door configuration and engine type, can affect the station dwell time, in this case, service time per passenger. LÄS MER

  4. 3. 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

  5. 4. 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.

  7. 5. Audio-based Motion Detection

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

    Författare :Gopal Gomatam; Filip Dujmic; [2021]
    Nyckelord :sonar; motion detection; audio frequencies; audio processing; Technology and Engineering;

    Sammanfattning : Motion detection is an essential technology and it has numerous use-cases, such as security tracking, automated door opening systems, and IP cameras. Commonly, passive infrared sensors or radio frequency sensors are used for motion detection. However, this thesis focuses on performing motion detection using existing hardware at audio frequencies.
