  1. 1. The Black Knight Rises : A mixed-methods analysis of the impacts of external support to regimes on the success of nonviolent resistance movements

    Master-uppsats, Uppsala universitet/Institutionen för freds- och konfliktforskning

    Författare :Samuel Maret; [2023]
    Nyckelord :Nonviolent resistance success; Black Knights; external support; Belarus;

    Sammanfattning : Nonviolent campaigns often extend beyond national boundaries, attracting the attention and involvement of international actors. However, our understanding of the effects of external support on the outcomes of nonviolent protests remains limited. Existing research mainly focuses on internal factors of success or concentrates on one or few cases. LÄS MER

  5. 4. Clustering of Unevenly Spaced Mixed Data Time Series

    Master-uppsats, KTH/Matematisk statistik

    Författare :Pierre Sinander; Asik Ahmed; [2023]
    Nyckelord :mixed data time series; unevenly spaced time series; clustering; dynamic time warping; Gower dissimilarity; time warping regularisation; numeriska och kategoriska tidsserier; ojämnt fördelade tidsserier; kluster analys; dynamic time warping; Gower dissimilaritet; regularisering av tidsförvränging;

    Sammanfattning : This thesis explores the feasibility of clustering mixed data and unevenly spaced time series for customer segmentation. The proposed method implements the Gower dissimilarity as the local distance function in dynamic time warping to calculate dissimilarities between mixed data time series. LÄS MER
