  1. 1. Construction and evaluation of a lossless image format, Carbonara

    Kandidat-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Viktor Rösler; [2023]
    Nyckelord :Data Compression; Image Compression; Image Format; Software Development;

    Sammanfattning : High-speed laser triangulation 3D cameras, such as the Ranger3 from SICK, transmit image data to a PC for processing. The camera’s operational speed is constrained by the capabilities of the transmission link. By compressing the data, the bandwidth requirements of the camera is reduced. LÄS MER

  3. 2. Hydrogen storage systems : Methodology and model development for hydrogen storage systems performance evaluation based on a transient thermodynamic approach

    Master-uppsats, Mälardalens universitet/Akademin för ekonomi, samhälle och teknik

    Författare :Kreshnik Margaritari; [2023]
    Nyckelord :Hydrogen; Hydrogen storage system; Hydrogen filling process; Hydrogen storage system operation; Hydrogen storage system design; Hydrogen fast filling; Hydrogen tank modelling;

    Sammanfattning : The overall performance of a hydrogen storage system can be affected by various parameters, such as operation and design parameters, but also by the state of the hydrogen contained inside the storage tanks. In this work, a methodology is developed to evaluate the state of the hydrogen during the filling process and its impact on the overall system performance under variable operation conditions and design parameters.

  4. 3. Jämförelse av datakomprimeringsalgoritmer för sensordata i motorstyrenheter

    M1-uppsats, KTH/Hälsoinformatik och logistik

    Författare :Malin Möller; Dominique Persson; [2023]
    Nyckelord :data compression; time-series data; embedded systems; engine control units; inverters; datakomprimering; tidsseriedata; inbyggda system; motorstyrenheter; växelriktare;

    Sammanfattning : Begränsad processor- och minneskapacitet är en stor utmaning för loggning avsensorsignaler i motorstyrenheter. För att kunna lagra större mängder data i dessakan komprimering användas. LÄS MER

  5. 4. Knowledge distillation for anomaly detection

    Master-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Nils Gustav Erik Pettersson; [2023]
    Nyckelord :;

    Sammanfattning : The implementation of systems and methodologies for time series anomaly detection holds the potential of providing timely detection of faults and issues in a wide variety of technical systems. Ideally, these systems are able to identify deviations from the normal behavior of systems even before any problems manifest, thus enabling proactive maintenance. LÄS MER

  7. 5. Efficient Traffic Monitoring in IoT Networks for Attack Detection at the Edge

    Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Engla Jansson; [2023]
    Nyckelord :;

    Sammanfattning : The Internet of Things has rapidly expanded over the years, and with this comes significant security risks, with attacks increasing at an alarming rate. A way to detect attacks in the network is by having each device send traffic monitoring information to an edge device that can investigate if any devices have been exploited. LÄS MER
