  1. 6. Fixed-Parameter Algorithms for Optimal Convex Partitions and Other Results

    Författare :Magdalene Grantson Borgelt; Data Vetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; control; Datalogi; numerical analysis; Convex Partition; Computer science; Triangulation; kontroll; system; numerisk analys; systems; Fixed-Parameter Algorithm; Spanning Tree;

    Sammanfattning : In this thesis I study two-dimensional geometric optimization problems for which it is difficult to find efficient, exact, deterministic algorithms. All known solutions to these problems require time that is exponential in the total size of the input. LÄS MER

  3. 7. Computational Methods for Computer Vision : Minimal Solvers and Convex Relaxations

    Författare :Viktor Larsson; Mathematical Imaging Group; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Vision; Geometric Vision; minimal solvers; Convex relaxation; Pose estimation;

    Sammanfattning : Robust fitting of geometric models is a core problem in computer vision. The most common approach is to use a hypothesize-and-test framework, such as RANSAC. In these frameworks the model is estimated from as few measurements as possible, which minimizes the risk of selecting corrupted measurements. LÄS MER

  4. 8. Asynchronous First-Order Algorithms for Large-Scale Optimization : Analysis and Implementation

    Författare :Arda Aytekin; Mikael Johansson; Lin Xiao; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; convex; optimization; asynchronous; algorithms; parallel; distributed; large-scale; big data; software; serverless; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Developments in communication and data storage technologies have made large-scale data collection more accessible than ever. The transformation of this data into insight or decisions typically involves solving numerical optimization problems. LÄS MER

  5. 9. Performing Punk : Subcultural Authentications and the Positioning of the Mainstream

    Författare :Erik Hannerz; Tora Holmberg; Philip Lalander; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; subculture; punk; mainstream; authentication; style; identity; cultural sociology; ethnography; convex; concave; patterns of meaning; Sociologi; Sociology;

    Sammanfattning : This thesis is about how and in opposition to what punk is defined and lived out by punks in Sweden and Indonesia. Arguing against the previous research’s presumption that subcultural meaning constitutes a single set of meaning, this study points to two patterned sets of meanings, each constructed out of several different definitions of the mainstream as well as the subcultural authentic.
