  1. 1. Compact Digital Track Maps: Enhancing Train Traveller Information at the Crossing of Accuracy and Availability : A comparative analysis of algorithms for generating compact representations of railway tracks

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

    Författare :Adam Andersson; [2023]
    Nyckelord :Train positioning; Digital track map; Digital map generation; Position measurement; Global navigation satellite system; Cartography; Tågpositionering; Digitala spårkartor; Generering av digitala kartor; Positionsmätning; Satellitnavigation; Kartograf;

    Sammanfattning : Trains are constrained to the railway tracks they operate on. This can be leveraged for absolute train positioning, where a train’s position can be mapped onto a digital track map (DTM). Extensive research has been dedicated to enhancing the accuracy of DTMs. LÄS MER

  3. 2. Machine learning methods for seasonal allergic rhinitis studies

    Master-uppsats, Linköpings universitet/Statistik och maskininlärning

    Författare :Zijie Feng; [2021]
    Nyckelord :Machine learning; Seasonal allergic rhinitis; Random forest; Partial least squares discriminant analysis; Bootstrap; Cubic smoothing splines; Single-cell RNA sequencing;

    Sammanfattning : Seasonal allergic rhinitis (SAR) is a disease caused by allergens from both environmental and genetic factors. Some researchers have studied the SAR based on traditional genetic methodologies. As technology develops, a new technique called single-cell RNA sequencing (scRNA-seq) is developed, which can generate high-dimension data. LÄS MER

  4. 3. Basal body temperature curves and fitting with periodic smoothing splines

    Master-uppsats, Lunds universitet/Matematik LTH

    Författare :Ingrid Odlen; [2019]
    Nyckelord :Basal Body Temperature; Ovulation; Fertility Prediction; Natural Cycles; Fertility Tracking; Smoothing Splines; Cubic; Periodic Smoothing Splines; Curve Fitting; BBT; Mathematics and Statistics;

    Sammanfattning : Fertility tracking phone apps are widely used by women today, in order to both achieve or prevent conception. Due to the health risks of hormone based contraceptions, many women opt for non-invasive methods, such as fertility tracking. LÄS MER
