  1. 6. Driver Modeling based on computational intelligence approaches : exploaration and Modeling driver-following data collected by an instrumented vehicle

    Författare :Xiaoliang Ma; Karl-Lennart Bång; Mark Dougherty; KTH; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : This thesis is concerned with modeling of driver behavior based on data collected from real traffic using an advanced instrumented vehicle. In particular, the focus is on driver-following behavior (often called car-following in transport science) for microscopic simulation of road traffic systems. LÄS MER

  3. 7. Data-Driven Approaches for Sparse Reflectance Modeling and Acquisition

    Författare :Tanaboon Tongbuasirilai; Jonas Unger; Ehsan Miandji; Jakob Wenzel; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BRDF; Reflectance modeling; Sparse representation; Compressed sensing; Factorization;

    Sammanfattning : Photo-realistic rendering and predictive image synthesis are becoming increasingly important and utilized in many application areas ranging from production of visual effects and product visualization to digital design and the generation of synthetic data for visual machine learning applications. Many essential components of the realistic image synthesis pipelines have been developed tremendously over the last decades. LÄS MER

  4. 8. View Planning and Refractive Modeling for Structure and Motion

    Författare :Sebastian Haner; Matematik LTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Computer Vision; Structure and Motion; 3D Reconstruction; View Planning; Refractive Modeling;

    Sammanfattning : This thesis presents contributions to structure-and-motion estimation, a central topic in the field of geometric computer vision. In particular, the problem of view planning is considered, and continuous and discrete optimization-based algorithms are given for how to plan the path of a sensor to its destination, while balancing the competing goals of path length and reconstruction accuracy.

    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metal technology; metallurgy; metal products; Metallurgi; materialteknik; Materiallära; Material technology; numerics; micromechanics; homogenization;

    Sammanfattning : This thesis addresses micromechanical modeling of materials using computational homogenization. On this topic, theoretical and computational issues are discussed, and numerical investigations of different material systems are performed. LÄS MER

  7. 10. Perspectives on the role of digital tools in students' open-ended physics inquiry

    Författare :Elias Euler; Bor Gregorcic; Cedric Linder; Konrad Schönborn; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; digital learning environments; modeling; semi-formalisms; microworlds; social semiotics; embodied cognition; disciplinary-relevant aspects; Physics with specialization in Physics Education; Fysik med inriktning mot fysikens didaktik;

    Sammanfattning : In this licentiate thesis, I present detailed case studies of students as they make use of simulated digital learning environments to engage with physics phenomena. In doing so, I reveal the moment-to-moment minutiae of physics students’ open-ended inquiry in the presence of two digital tools, namely the sandbox software Algodoo and the PhET simulation My Solar System (both running on an interactive whiteboard).
