  1. 1. Mobile Satellite Broadcast and Multichannel Communications : analysis and design

    Författare :Cristoff Martin; Björn Ottersten; Jack Winters; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Signalbehandling; communications; satellite broadcast; mobile; MIMO; asymptotic analysis; spatial multiplexing; Signalbehandling; Signal processing; Signalbehandling;

    Sammanfattning : In this thesis, analytical analysis and design techniques for wireless communications with diversity are studied. The impact of impairments such as correlated fading is analyzed using statistical models. Countermeasures designed to overcome, or even exploit, such effects are proposed and examined. LÄS MER

  2. 2. Building a coherent hydro-climatic modelling framework for the data limited Kilombero Valley of Tanzania

    Författare :Alexander Koutsouris; Steve W. Lyon; Jan Seibert; Mekonnen Gebremichael; Stockholms universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Hydrology; Precipitation; Recession analysis; End - member mixing analysis; EMMA; GLUE; HBV; down scaling; Quantile mapping; CFSR; CMORPH; CRU; GPCC; ERA - i; MERRA; TRMM; UDEL; Satellite; Reanalysis; Kilombero; Tanzania; Eastern Africa; Africa; Physical Geography; naturgeografi;

    Sammanfattning : This thesis explores key aspects for synthesizing data across spatiotemporal scales relevant for water resources management in an Eastern Africa context. Specifically, the potential of large scale global precipitation datasets (GPDs) in data limited regions to overcome spatial and temporal data gaps is considered. LÄS MER

  3. 3. The GLAST Satellite Calorimeter

    Författare :Georg Johansson; Avdelningen för Biomedicinsk teknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; GLAST; CsI Tl crystals; electromagnetic calorimeter; hodoscopic assembly; satellite-born detector; Dark Matter; cosmic gamma radiation;

    Sammanfattning : The Gamma Ray Large Area Space Telescope (GLAST) is a multi-national satellite mission with aim to study the high-energy gamma ray sky. The main instrument is the Large Area Telescope (LAT) that consists of 16 towers, each housing a silicon strip precision tracker and a CsI(Tl) calorimeter. LÄS MER

  4. 4. Landscape from space : geographical aspects on scale, regionalization and change detection

    Författare :Ola Hall; Risto Kalliola; Stockholms universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Regionalization; Scale; Change detection; Multiscale analysis; Objectspecific analysis; Watershed transformation; Landscape; Satellite data; Geography; Complex systems theory; Fuzzy set theory; Multicriteria-evaluation.; Human geography; Kulturgeografi; Human Geography; kulturgeografi;

    Sammanfattning : Landscapes are complex systems composed of multiscale hierarchically organized entities that interact within unique spatial and temporal scales. These interactions result in scaledependent spatial patterns that visually change depending upon the scale at which they are observed. LÄS MER

  5. 5. A Software-Defined Baseband for Satellite Ground Operations : Feasibility and Design

    Författare :Moses Browne Mwakyanjala; Jaap van de Beek; Élcio Jeronimo de Oliviera; Jaan Praks; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Software-Defined Radios; Satellite Ground Operations; Satellite Telemetry; Command; and Tracking; Onboard space systems; Rymdtekniska system;

    Sammanfattning : Satellite telemetry, tracking, and command (TT&C) is a crucial activity needed to maintainthe health of a spacecraft or sometimes to facilitate payload data download. TT&Cground operations are facilitated by a communication device known in the TT&C communityas a baseband. LÄS MER
