  1. 21. Secure and Privacy Preserving Vehicular Communication Systems: Identity and Credential Management Infrastructure

    Författare :Mohammad Khodaei; Panos Papadimitratos; Tomas Olovsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Vehicular Communications; Security; Privacy; Access Control; Identity and Credential Management; Vehicular PKI; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : Vehicular Communication (VC) systems can greatly enhance road safety and transportation efficiency. Vehicles are equipped with sensors to sense their surroundings and the internal Controller Area Network (CAN) bus. Hence, vehicles are becoming part of a large-scale network, the so-called Internet of Vehicles (IoV). LÄS MER

    Författare :Kun Wang; Lena Wosinska; Jiajia Chen; Kjell Brunnström; Jason P. Jue; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fiber To The Home FTTH ; Mobile backhaul fronthaul; Next Generation Optical Access network; Optical Transport Network OTN ; Network migration; Techno-Economic; Total Cost of Ownership TCO ; Capital expenditures CAPEX ; Operational expenditures OPEX ; Softer Defined Networking SDN ; Informations- och kommunikationsteknik; Information and Communication Technology; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : By 2020 there will be 50 billion connected devices over the Internet. With the fast-increasing data traffic demand in both fixed and mobile networks, network operators need to migrate networks towards next generation solutions. LÄS MER

  4. 23. A methodology for situated and effective design of haptic devices

    Författare :Xuan Sun; Kjell Andersson; Ulf Sellgren; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Design optimization; haptic devices; metamodel; multi-criteria; situatedness; Machine Design; Maskinkonstruktion;

    Sammanfattning : The realism of virtual surgery through a surgical simulator depends largely on the precision and reliability of the haptic device. The quality of perception depends on the design of the haptic device, which presents a complex design task due to the multi-criteria and conflicting character of the functional and performance requirements.

  5. 24. Numerical stability studies of one-phase and immiscible two-phase jets and wakes

    Författare :Outi Tammisola; Daniel Söderberg; Fredrik Lundell; Rama Govindarajan; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Fluid mechanics; Strömningsmekanik;

    Sammanfattning : The initial linear instability growth of two-dimensional plane wakes and jetsis investigated, by temporal two-dimensional global modes, and local spatialstability analysis. Comparisons are also made to experiments, direct numericalsimulations, and methods designed for weakly-non-parallel flows. LÄS MER

  7. 25. Characterization of Magnetic Nanoscale Systems: From Molecules to Particles and Self-Assembled Chains

    Författare :Claudiu Bulbucan; NanoLund: Centre for Nanoscience; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Magnetism; Magnetic nanoparticles; Exchange bias; Single molecule magnets; Magnetic nanochains; X-ray magnetic circular dichroism;

    Sammanfattning : This thesis characterizes magnetic nanoscale systems with increasing size and aspect ratio using synchrotron radiation-based spectroscopy and microscopy techniques, combined with conventional magnetometry. The systems studied are molecular magnets, bimagnetic nanoparticles and self-assembled magnetic nanochains. LÄS MER
