  1. 1. Transfer learning applied to a deep learning system for cardiac abnormality classification in electrocardiograms

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Adrian Campoy Rodriguez; [2022]
    Keywords : Deep Learning; ECG; Wavelet Transform; Scattering Transform; Transfer Learning; Canonical Correlation Analysis; Djupinlärning; EKG; wavelettransform; scatteringtransform; överföringsinlärning; kanonisk korrelationsanalys;

    Abstract : Cardiovascular diseases are a leading cause of death globally. Early diagnosis and treatment is of prime importance to prevent or mitigate health complications. Electrocardiogram (ECG) is a standard test modality used for early diagnosis of arrhythmias. The standard ECG uses 12 leads (i. READ MORE

  3. 2. Detecting Social Breathing : Quantitative signs of interaction in conversational data

    University essay from Umeå universitet/Institutionen för fysik

    Author : Cordelia Horns; [2022]
    Keywords : time series; interaction; human interaction; data analysis; wavelet analysis; machine learning; Social Breathing;

    Abstract : Human interaction has been a focus of study in psychology for a long time, but until recentlyonly very specific aspects of interaction have been considered. This approach leads to studiesthat gave insights into certain contexts, like parent-child or patient-clinician dynamics [1], [2]. READ MORE

  4. 3. Automatic post-fault analysis based on disturbance data stored in substation devices : Approach towards the preventive maintenance

    University essay from KTH/Hälsoinformatik och logistik

    Author : Riad Yalda; Miroslav Urosevic; [2019]
    Keywords : COMTRADE file; preventive maintenance; relay protection; automatic post-fault analysis; IEC 61850; wavelet transform.; COMTRADE filer; förebyggande underhåll; reläskydd; automatisk efterfelsanalys; IEC 61850; wavelettransform.;

    Abstract : This report studies the possibilities of minimizing unplanned maintenance work and improving the availability of power supply by enabling preventive maintenance in power systems, without having to make additional investments in the existing systems. This was done using information from COMTRADE files (disturbance recording files) that are created in the event of a fault in the power system. READ MORE

  5. 4. Nonstationary feature extraction techniques for automatic classification of impact acoustic signals

    University essay from Datateknik

    Author : Yasemi Bekiroglu; [2008]
    Keywords : railway sleepers;

    Abstract : Condition monitoring of wooden railway sleepers applications are generallycarried out by visual inspection and if necessary some impact acoustic examination iscarried out intuitively by skilled personnel. In this work, a pattern recognition solutionhas been proposed to automate the process for the achievement of robust results. READ MORE

    University essay from KTH/Geodesi och satellitpositionering

    Author : Maria Irene Rangel Luna; [2006]
    Keywords : ;

    Abstract : Landuse and land-cover classification from high resolution imagery has been seen as challenging by theremote sensing society. The high variability from pixel to pixel makes the use of pixel-based classifiersobsolete. READ MORE
