  1. 1. The role of duplex scanning in the management of carotid artery disease

    Författare :Karl Logason; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Surgery; Duplex scanning; Doppler spectral analysis; duplex criteria; Doppler angle of insonation; carotid artery stenosis; carotid endarterectomy; spontaneous cervical artery dissection; Kirurgi; Surgery; Kirurgi; Surgery; kirurgi;

    Sammanfattning : Extracranial carotid artery disease, mainly due to atherosclerosis, is a common cause of stroke. The risk for future stroke can be reduced in selected patients by carotid endarterectomy (CEA). Duplex scanning has been increasingly used for diagnosis of carotid artery disease. LÄS MER

  3. 2. Super duplex stainless steels : Microstructure and propertiesof physically simulated base and weld metal

    Författare :Vahid Hosseini; Leif Karlsson; Högskolan Väst; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Super duplex stainless steel; weld metal; physical simulation; phase balance; precipitation; secondary phases; corrosion; nitrogen loss; arc heat treatment; production technology; Production Technology; Produktionsteknik; Manufacturing and materials engineering; Produktions- och materialteknik;

    Sammanfattning : High-temperature processing and application of super duplex stainless steel(SDSS) are associated with the risk of changes in the ferrite/austenite balance and precipitation of secondary phases. This study was therefore aimed at improving knowledge about effects of thermal cycles on the microstructure and properties of SDSS base and weld metal. LÄS MER

  4. 3. Resource management for network-assisted D2D communication

    Författare :Demia Della Penda; Mikael Johansson; Emil Björnson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Electrical Engineering; Elektro- och systemteknik;

    Sammanfattning : During the last decade, the widespread use of smart devices and mobile applications has led to a massive growth of the mobile traffic demand. Efficiency and scalability are therefore key criteria for the development of future cellular systems, in which device-to-device (D2D) communication is recognized as one of the promising technologies.
