  1. 1. Load Classification with Machine Learning : Classifying Loads in a Distribution Grid

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Institutionen för teknikvetenskaper

    Författare :Jonathan Kristensson; [2019]
    Nyckelord :Power systems; machine learning; smart grid; load profiles; Velander s formula; load classification; clustering; regression; data quality; Kraftsystem; maskininlärning; smarta elnät; lastprofiler; Velanders formel; lastklassificering; klustring; regression; datakvalitet;

    Sammanfattning : This thesis explores the use of machine learning as a load classifier in a distribution grid based on the daily consumption behaviour of roughly 1600 loads spread throughout the areas Bromma, Hässelby and Vällingby in Stockholm, Sweden. Two common unsupervised learning methods were used for this, K-means clustering and hierarchical agglomerative clustering (HAC), the performance of which was analysed with different input data sets and parameters.

  4. 3. Soot particles from shipping: Analysing emission factors

    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Nicklas Mauritzson; [2015]
    Nyckelord :Ship emission; emission factor; soot; black carbon; measurement; SECA; Gothenburg; Sweden; Earth and Environmental Sciences;

    Sammanfattning : Emissions of air pollutants from shipping in Europe result in about 50 000 premature deaths every year. Soot particles, also called black carbon, are particularly hazardous to human health when inhaled. The adverse health effects are especially a danger in coastal areas, but the particles can travel further away with the wind. LÄS MER

  5. 4. Evaluation of the retinal ON- and OFF-responses in the dog ERG

    Uppsats för yrkesexamina på grundnivå, SLU/Dept. of Clinical Sciences

    Författare :Charlotte Kristensson; [2014]
    Nyckelord :electroretinography; ERG; dog; cones; ON-response; OFF-response; elektroretinografi; hund; tappar; ON-respons; OFF-respons;

    Sammanfattning : The aim of the study was to examine the retinal ON- and OFF-pathways of the canine electroretinogram (ERG). The ON- and OFF-pathways are used to distinguish objects from their backgrounds. A dark object is discernible from a lighter background using the OFFpathway and the ON-pathway is used to descry a light object upon a darker background. LÄS MER
