  3. 22. Robust Estimation of Motion Parameters and Scene Geometry : Minimal Solvers and Convexification of Regularisers for Low-Rank Approximation

    Författare :Marcus Valtonen Örnhag; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Computer Vision; Visual Odometry; Simultaneous Localization and Mapping; minimal solvers; Convex relaxations; Structure from motion;

    Sammanfattning : In the dawning age of autonomous driving, accurate and robust tracking of vehicles is a quintessential part. This is inextricably linked with the problem of Simultaneous Localisation and Mapping (SLAM), in which one tries to determine the position of a vehicle relative to its surroundings without prior knowledge of them.

    Sammanfattning : The explosive growth of data in information society poses significant challenges in the timely delivery of information in the context of communication networks. Hence, optimal utilization of scarce network resources is crucial. LÄS MER

  5. 24. Efficient Modelling and Synthesis of Data Intensive Reconfigurable Systems

    Författare :Per Andersson; Institutionen för datavetenskap; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; kontroll; Systems engineering; numerisk analys; system; control; Datalogi; numerical analysis; systems; Data Flow Graphs; Data Flow Modlling; computer technology; Data- och systemvetenskap; Computer science; Hardware Compilation; Synthesis;

    Sammanfattning : Digital systems are integrated in our environment and have become a natural part of our every day life. As we rely more on these systems our expectations on them increases. We expect them to perform new tasks, communicate and cooperate. The complexity of these systems are increasing. LÄS MER

  7. 25. Novelty and change detection radiation physics experiments

    Författare :Abbas Jabor; Thomas Lindblad; Örjan Skeppstedt; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; Fysik;

    Sammanfattning : This thesis deals with the detection and analysis of low-level natural and induced radioactivity. Using high energy-resolution Ge detectors in low-level counting areas airborne radioactivity’s like Be-7 and Cs-137 have been investigated. The experimental facilities and techniques are described in some detail. LÄS MER
