  1. 1. Temporal and spatial dynamics in subarctic peat plateaus and thermokarst lakes

    Detta är en avhandling från Stockholm : Department of Physical Geography and Quaternary Geology (INK), Stockholm University

    Författare :A. Britta K. Sannel; Stockholms universitet.; [2010]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Peatlands; permafrost; subarctic; peat plateau; thermokarst lake; macrofossil analysis; carbon nitrogen ratio; peat accumulation; carbon accumulation; remote sensing; binary encoding; time-series analysis; Physical Geography; naturgeografi;

    Sammanfattning : Permafrost peatlands are widespread at high northern latitudes and are important soil organic carbon reservoirs. A future warming in these areas, as suggested by global climate models, can cause thawing and increased ground subsidence (thermokarst), resulting in changes in surface hydrology and ecosystem functioning.

  2. 2. Photonic Techniques for Real-Time Analog-to-Digital Conversion

    Detta är en avhandling från Stockholm : Department of Physical Geography and Quaternary Geology (INK), Stockholm University

    Författare :Johan Stigwall; [2006]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; tunable THz generation; photonic time-stretch; photonic sampling; Photonic analog-to-digital conversion; optical signal processin; photonic binary encoding; microwave photonics; photonic thresholding;

    Sammanfattning : All-electronic analog-to-digital conversion (ADC) technology is limited by the timing accuracy and inherent speed of semiconductor materials. Photonic techniques, however, can potentially enable real-time ADC at a considerably wider bandwidth, higher sample rate and/or resolution, thanks to the availability of extremely accurate optical clocks and the immense bandwidth of optical systems.

  3. 3. Coding of fractal binary images with contractive set mappings composed of affine transformations

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Niclas Wadströmer; Linköpings universitet.; Linköpings universitet.; [2001]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : There are several efficient algorithms by which one can generate approximations of binaryattractors induced from contractive set mappings which are composed of affine mappings.There are also complex attractors resembling natural-looking images where the attractors areinduced from only a few affine mappings which can be represented with a few bits.

  4. 4. On Symbolic Analysis of Discrete Event Systems Modeled as Automata with Variables

    Detta är en avhandling från Linköping : Linköpings universitet

    Författare :Zhennan Fei; [2012]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Partitioning Techniques; Discrete Event Systems; Supervisory Control Theory; Extended Fi- nite Automata; Binary Decision Diagrams;

    Sammanfattning : In benefit of the current revolution in computer technology, nowadays, society is dependent on dedicated computer-aided systems more than ever to assist us in every aspect of daily life. Thereby, designing reliable control logic of those systems to avoid malfunctioning behavior is of importance. LÄS MER

  5. 5. On Tailbiting Codes from Convolutional Codes

    Detta är en avhandling från Department of Information Technology, Lund Univeristy

    Författare :Per Ståhl; Lunds universitet.; Lund University.; [2001]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; computer technology; Systems engineering; Teknik; Technological sciences; encoder inverse; systematic feedback encoder; state complexity; trellis; tailbiting termination method; tailbiting code; channel coding; convolutional code; Data- och systemvetenskap; Informatics; systems theory; Informatik; systemteori;

    Sammanfattning : Popular Abstract in Swedish Denna avhandling behandlar en speciell typ av felrättande koder som kallas tailbitingkoder. Syftet med en felrättande kod är att korrigera fel som kan uppkomma på grund av brus och störningar då digital information överförs från sändare till mottagare... LÄS MER
