  1. 1. Distributed Estimation of Network Cardinalities

    Författare :Riccardo Lucchese; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Reglerteknik; Control Engineering;

    Sammanfattning : In distributed applications knowing the topological properties of the underlying communication network may lead to better performing algorithms. For instance, in distributed regression frameworks, knowing the number of active sensors allows to correctly weight prior information against evidence in the data. LÄS MER

  3. 2. The Origin-Destination Matrix Estimation Problem : Analysis and Computations

    Författare :Anders Peterson; Jan Lundgren; Torbjörn Larsson; Lars-Göran Mattsson; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Traffic modelling; Travel demand; Origin--Destination matrix; Traffic flow observation; Detector allocation; Estimation.; OD-matris; Trafikflödesobservation; Detektorallokering; Skattning; Trafikmodellering; Reseefterfrågan; Optimization; systems theory; Optimeringslära; systemteori;

    Sammanfattning : For most kind of analyses in the field of traffic planning, there is a need for origin--destination (OD) matrices, which specify the travel demands between the origin and destination nodes in the network. This thesis concerns the OD-matrix estimation problem, that is, the calculation of OD-matrices using observed link flows. LÄS MER

  5. 4. 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.
