  1. 1. Extraction of Global Features for enhancing Machine Learning Performance

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

    Författare :Abyel Tesfay; [2023]
    Nyckelord :Machine Learning; Deep Learning; Feature Extraction; Global Features; Time-series data; Bioprocessing; Maskininlärning; Djupinlärning; Funktionsextraktion; Globala Funktioner; Tidsserie data; Biobearbetning;

    Sammanfattning : Data Science plays an essential role in many organizations and industries to become data-driven in their decision-making and workflow, as models can provide relevant input in areas such as social media, the stock market, and manufacturing industries. To train models of quality, data preparation methods such as feature extraction are used to extract relevant features. LÄS MER

  3. 2. Shock absorber dynamics : A parameter study of damper physical quantitiesand their effect on automobile comfort and control

    Master-uppsats, KTH/Väg- och spårfordon samt konceptuell fordonsdesign

    Författare :David Stridfeldt; Jonsson Gustav; [2023]
    Nyckelord :Shock absorbers; dampers; parameter study; valve dynamics; comfort; control; Stötdämpare; dämpare; parameterstudie; ventildynamik; komfort; kontroll;

    Sammanfattning :   Damper performance is most commonly characterized by the damper’s forcevelocity behaviour. Different damper layouts and valving methods for creating oil flow constrictions bring different physical properties, outside of this conventional measure. LÄS MER
