  1. 1. Deep Learning Based Out-of-focus Detection on Surveillance Footage

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Hanna Bengtsson; Teodora Kerac; [2023]
    Nyckelord :Deep Learning; CNN; Out-of-focus detection; Mathematics and Statistics;

    Sammanfattning : Loss of focus in surveillance cameras can occur due to factors such as environmental aspects, sabotage or system errors. The focus loss leads to degraded footage that is of no use for either post-investigation or automatic video analysis. LÄS MER

  3. 2. A General Purpose Analog Circuit to Accumulate Data From Resistive Sensors

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

    Författare :Karl Höjlund; Alan Alhallak; [2022]
    Nyckelord :Data acquisition; Wheatstone bridge; Analog conditioning; Digital potentiometer;

    Sammanfattning : Minimizing the need to physically adjust hardware platforms used for sensor measurements during the construction phase of an electric vehicle can be beneficial. Since different sensors have different measuring ranges a hardware platform used for a specific sensor might not work for another one, without physically tampering with it. LÄS MER

  5. 4. Tampering Classification Using Accelerometer Data

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Mikael Lindholm; Linus Lindgren; [2017]
    Nyckelord :machine learning; classification; accelerometer; support vector machine; doorstation; tampering detection; Mathematics and Statistics;

    Sammanfattning : Network Video Door Stations are IP-based door stations for two-way communication, identification, and remote entry control. They have a number of different sensors e.g video, audio and accelerometer that can measure external data. LÄS MER

  7. 5. Losses in the Electric Grid on Pemba, Tanzania

    Kandidat-uppsats, KTH/Energiteknik

    Författare :Lovisa Gelotte; Olle Wahlquist; [2015]
    Nyckelord :;

    Sammanfattning : Reliable energy is fundamental for a region’s capacity for sustainable development. The island Pemba, which together with Unguja forms Zanzibar, is a semi-autonomous part of Tanzania. The electric power supply on the island is unreliable and blackouts are frequently occurring.
