  1. 21. Image Analysis using the Physics of Light Scattering

    Författare :Peter Nillius; KTH; []
    Nyckelord :computer vision; shading; illumination; reflectance; image irradiance;

    Sammanfattning : Any generic computer vision algorithm must be able to copewith the variations in appearance of objects due to differentillumination conditions. While these variations in the shadingof a surface may seem a nuisance, they in fact containinformation about the world. LÄS MER

  3. 22. Decentralized Network Optimization in Wireless Networks

    Författare :Yuzhe Xu; Carlo Fischione; Tommaso Melodia; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Distributed estimation and distributed resource allocation are two important services in future cyber-physical wireless networks. The former aims to estimate, or track, physical variables of a phenomenon monitored by a wireless network, whereas the latter aims to optimally assign the limited communication resources to the nodes in a wireless network.

  4. 23. Optimal Networking in Wirelessly Powered Sensor Networks

    Författare :Rong Du; Carlo Fischione; Ming Xiao; Aylin Yener; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Wireless energy transfer; network lifetime; energy beamforming; IoT; smart cities; sensor networks; scheduling; optimization; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Wireless sensor networks (WSNs) are nowadays widely used for the long-term monitoring of small or large regions, such as lakes, forests, cities, and industrial areas. The performance of a WSN typically consists of two aspects: i) the monitoring performance, e.g. LÄS MER

  5. 24. Resource Allocation for Mobile Edge Computing Systems

    Författare :Ming Zeng; Viktória Fodor; Gunnar Karlsson; Di Yuan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; mobile edge computing MEC ; orthogonal multiple access OMA ; non-orthogonal multiple access NOMA ; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : The rapid development of mobile information industry has led to the emergence of various mobile applications in areas such as industrial automation, health care or transportation. These applications often require heavy computations with strict latency requirement, which may surpass the processing abilities of the mobile devices. LÄS MER

  7. 25. Analytic and data-driven methods for 3D electron microscopy

    Författare :Gustav Zickert; Pär Kurlberg; Ozan Öktem; Timo Koski; Roy Lederman; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The central theme of this thesis is theoretical and algorithmic aspects of 3D electron microscopy (3D-EM). In particular, the thesis explores three parts of this theme. The first part concerns analysis of forward operators that, compared to those traditionally used, better account for the wave properties of the imaging electron. LÄS MER
