  2. 11. Short-Term Traffic Prediction in Large-Scale Urban Networks

    Author : Matej Cebecauer; Erik Jenelius; Wilco Burghout; Balázs Kulcsár; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; travel time prediction; short-term travel time prediction; traffic prediction; clustering; partitioning; spatio-temporal partitioning; large-scale prediction; PPCA; 3D speed map; Transportvetenskap; Transport Science;

    Abstract : City-wide travel time prediction in real-time is an important enabler for efficient use of the road network. It can be used in traveler information to enable more efficient routing of individual vehicles as well as decision support for traffic management applications such as directed information campaigns or incident management.

  4. 12. Low Rank Matrix Factorization and Relative Pose Problems in Computer Vision

    Author : Fangyuan Jiang; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Geometric Computer Vision; Low-rank Matrix Factorization; Relative Pose;

    Abstract : This thesis is focused on geometric computer vision problems. The first part of the thesis aims at solving one fundamental problem, namely low-rank matrix factorization. We provide several novel insights into the problem. In brief, we characterize, generate, parametrize and solve the minimal problems associated with low-rank matrix factorization. READ MORE

  5. 13. Computer Vision Using Rich Features - Geometry and Systems

    Author : Björn Johansson; Matematik LTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; imagebased rendering; Computer vision; view synthesis; Mathematics; Matematik;

    Abstract : In this thesis a number of computer vision problems is discussed, in particular we study the problem of view synthesis. The focus is on using complex features to determine the geometry of the scene and the cameras, in contrast to traditional point-based methods. READ MORE

  6. 14. Small town, big move : Constructions of place in transiting mining communities

    Author : Eugenia Segerstedt; Lena Abrahamsson; Mats Jakobsson; Kristina Johansson; Gry Paulgaard; Luleå tekniska universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; construction of place; Gällivare; Kiruna; transformation; rural studies; urban change; Arbetsvetenskap; Human Work Sciences;

    Abstract : The dissertation accounts for construction of place in mining communities as they undergo a major urban transformation. In the 2010s, urban centres in the northern Sweden mining communities of Gällivare and Kiruna entered a new execution phase of a large-scale transformation precipitated by ground subsidence caused by mining activities, a transformation that continues.

  7. 15. Mitigation of Power-Frequency Magnetic Fields With Applications to Substations and Other Parts of the Electric Network

    Author : Ener Salinas; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; substation; power-frequency magnetic fields; EMC; FEM; busbars; transformers; field mitigation; eddy currents;

    Abstract : In recent times, electromagnetic emissions from various electrical components have induced more than one debate whether they represent a harmful influence to our health. In addition, interferences caused by power frequency magnetic fields (PFMFs) on electron beam based electronic equipment (e.g. READ MORE
