  1. 16. Testing and Integration of Machine Learning Components for Image Classification : Testning och integration av machine learning komponenter förbildklassificering

    Master-uppsats, Linköpings universitet/Institutionen för datavetenskap

    Författare :Ahmad Hanash; [2023]
    Nyckelord :MLOps; Safety; Testing; Robustness; Integration; Verification;

    Sammanfattning : As ML (Machine Learning) and deep neural networks get more used in many systems,the need to understand and test such systems becomes more actual. When designing a newsystem that contains ML models, the safety of this system becomes inevitably important. LÄS MER

  3. 17. The design of a hydraulic equalizer bar for the feeding mechanism on forest harvester heads

    Uppsats för yrkesexamina på avancerad nivå, Luleå tekniska universitet/Institutionen för teknikvetenskap och matematik

    Författare :Arvid Söderlund; [2023]
    Nyckelord :Harvester; Harvester head; Komatsu Forest; Hydraulics; Equalizer bar; Parallellstag; Stag; Skogsmaskin; Skördare; Aggregat; Skog;

    Sammanfattning : Due to the importance of a correct tree placement and the wear that occurs to equalizer bars inharvester heads, Komatsu Forest AB in Umeå was interested if the bar could be replaced with ahydraulic system. According to Komatsu, the problems were that the equalizer bars that are responsible forsynchronizing the delimbing knives and feeding mechanism add weight, take up space and have atendency to break before their life expectancy.

  4. 18. Antenna measurements of HF antennas using low cost UAVs

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

    Författare :Ruimin Ma; Jinting Zhang; [2023]
    Nyckelord :Antenna; HF; UAV; Radiation Pattern; Antenna; HF; UAV; Strålningsmönster;

    Sammanfattning : High-frequency signal far-field measurement systems usually involve the use of complex and expensive equipment, since the measurements must be made at a distance of multiple wavelengths from the antenna. Helicopter surveyors are commonly utilized. LÄS MER

  5. 19. Multiplexing NFC Antennas : An evaluation of the technique and its limitations

    Kandidat-uppsats, Jönköping University/JTH, Avdelningen för datavetenskap

    Författare :Viktor Gustafsson; Per Ottosson; [2023]
    Nyckelord :AAT; BER; DSR; Impedance; Multiplexer; NFC; Wireless Technology;

    Sammanfattning : Introduction This study aims to investigate the possibility of driving multiple NFC antennas with a single NFC-controller by using a multiplexer. An artifact was developed and experiments were conducted in order to evaluate the design choice and in addition, to observe the impact of a multiplexer in an NFC system with respect to the number of successful tag detections, bit error rate (BER), the utilization of automatic antenna tuning (AAT) and the physical distance to the NFC tag.

    Sammanfattning : Testing, verification and validation of sensors, components and systems is vital in the early-stage development of new cars with computer-in-the-car architecture. This can be done with the help of the existing technique, hardware-in-the-loop (HIL) testing which, in the close loop testing case, consists of four main parts: Real-Time Simulation Platform, Sensor Simulation PC, Interface Unit (IU), and unit under test which is, for instance, a Vehicle Computing Unit (VCU).
