  3. 12. Characteristics of Vertical Forest Backscatter Profiles Measured using Radar Tomography

    Författare :Patrik Bennet; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; LANTBRUKSVETENSKAPER; AGRICULTURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Forest remote sensing; L-band; above-ground biomass; P-band; vertical reflectivity profiles; radar tomography; temporal backscatter variations;

    Sammanfattning : Forests are an integral part of the Earth’s climate system, having shaped the conditions of life throughout millions of years, but the coverage and conditions of forests are under rapid change. To monitor this change and predict the impact on climate, yearly global mapping of forest Above-Ground Biomass (AGB) is needed. LÄS MER

    Sammanfattning : The avalanche in mobile data consumption represents a big challenge for mobile operators. The efficient use of radio resources, e.g. technology, infrastructure and spectrum, is needed to meet the new capacity requirement in the mobile networks. LÄS MER

  5. 14. Mixers and Multifunctional MMICs for Millimeter-Wave Applications

    Författare :Sten Gunnarsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; G-band; double-balanced Gilbert mixer; sub-harmonically pumped resistive mixer; pHEMT; receiver; image reject mixer; dual-quadrature mixer; balanced resistive mixer; resistive mixer; 220 GHz; high data rate; drain mixer; 53 GHz; single-chip; V-band.; radiometer; mixer; broadband wireless communication; multifunctional; MMIC; GaAs; mHEMT; transmitter; 60 GHz;

    Sammanfattning : This thesis treats the design and characterization of different mixer and multifunctional monolithic microwave integrated circuits (MMICs) in GaAs pHEMT and mHEMT technologies. The MMICs operate at the V (50 – 75 GHz) and G (140 – 220 GHz) bands and several of them demonstrate state-of-the-art performance, level of integration, novel topologies, and/or novel functionality.

  7. 15. Myofibrillens finstruktur i tvärstrimmig skelettmuskulatur

    Författare :Anne-Christine Edman; Michael Sjöström; Umeå universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Muscle; muscle fibre; fibre type; myofilament; A-band; M-band; cryo-ultramicrotomy; electron microscopy; image analysis;

    Sammanfattning : The detailed structure of the myofibrillar material in fibres from different muscles has been studied. Specimens have been obtained from human muscles and from different muscles frequently examined in experimental studies. Both light- and electron microscopical techniques have been used. LÄS MER
