  1. 6. On data structures and memory models

    Författare :Johan Karlsson; Luleå tekniska universitet; []
    Nyckelord :;

    Sammanfattning : In this thesis we study the limitations of data structures and how they can be overcome through careful consideration of the used memory models. The word RAM model represents the memory as a finite set of registers consisting of a constant number of unique bits. LÄS MER

  3. 7. Towards Fully Automatic Optimal Shape Modeling

    Författare :Johan Karlsson; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Parameterization Invariance; Benchmarking; Interpretation; Segmentation; Alignment; Shape Modeling; MDL;

    Sammanfattning : Shape models and the automatic building of such models have proven over the last decades to be powerful tools in image segmentation and analysis. This thesis makes contributions to this field. The segmentation algorithm typically uses an objective function summing up contributions from each sample point. LÄS MER

  4. 8. Computationally efficient exact remodeling of optimization programs with applications to autonomous driving

    Författare :Johan Karlsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Autonomous driving; Real-time implementation; Model predictive control; Convex optimization;

    Sammanfattning : The future of autonomous vehicles is rapidly approaching and the published and available research, both from vehicle manufacturers and universities, is abundant. This new technology promises less pollution, lower accident rates, decreased congestion and the possibility to relax or work while a vehicle takes you where you need to go. LÄS MER
