  1. 1. Audio Anomaly Detection in Cars

    Master-uppsats, Göteborgs universitet/Institutionen för matematiska vetenskaper

    Författare :Asma Hussein; [2023-09-11]
    Nyckelord :Audio Anomaly detection; Outlier detection; Machine learning; Mel Frequency; Chroma;

    Sammanfattning : Audio anomaly detection in the context of car driving is a crucial task for ensuring vehicle safety and identifying potential faults. This paper aims to investigate and compare different methods for unsupervised audio anomaly detection using a data set consisting of recorded audio data from fault injections and normal "no fault" driving.

  4. 3. Automating Feature-Extraction for Camera Calibration Through Machine Learning and Computer Vision

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

    Författare :Elias Åkeborg; [2021]
    Nyckelord :Machine learning; Computer vision; Feature-extraction; Classification; Camera Calibration; DeepLab; U-Net; Ridge Detection; Sub-pixel optimization; Artificial Intelligence; Technology and Engineering;

    Sammanfattning : Machine learning as a field has expanded in an explosive manner, with more companies interested in using the technology. One of these companies, Spiideo, uses Machine learning to automatically stream and record sports, highlighting key events - all automatically without a cameraman. LÄS MER

  5. 4. Pitcher : An automatic guitar tuner

    Kandidat-uppsats, KTH/Mekatronik

    Författare :Hannes Andersson; John Sjöberg; [2021]
    Nyckelord :Arduino; mechatronics; autocorrelation; guitar tuner; pitch detection algorithm; Arduino; mekatronik; autokorrelation; gitarrstämmare; tonavläsning;

    Sammanfattning : Pitcher is a prototype which makes it easier for inexperienced guitar players to tune their guitars without any prior knowledge required. This thesis will explore how the construction varies between the usage of DC and a stepper motor, how reliable the tuner is and how long it takes to tune the guitar. LÄS MER

  7. 5. The visibility of double neutron star binaries to LISA

    Kandidat-uppsats, Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Anatole Storck; [2021]
    Nyckelord :gravitational waves; LISA; neutron stars; orbital simulations; Runge-Kutta method; Physics and Astronomy;

    Sammanfattning : Double neutron star binaries (DNSBs) in the mHz gravitational wave (GW) regime are an important group of objects which the GW detector LISA will be able to observe. The detection and parametrization of these objects will help develop our current understanding of neutron star formation and evolution. LÄS MER
