  1. 1. Distribution Preserving Quantization

    Detta är en avhandling från Stockholm : KTH Royal Institute of Technology

    Författare :Minyue Li; KTH.; [2011]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TECHNOLOGY Information technology Telecommunication; TEKNIKVETENSKAP Informationsteknik Telekommunikation;

    Sammanfattning : In the lossy coding of perceptually relevant signals, such as sound and images, the ultimate goal is to achieve good perceived quality of the reconstructed signal, under a constraint on the bit-rate. Conventional methodologies focus either on a rate-distortion optimization or on the preservation of signal features. LÄS MER

  3. 2. Bending the Kuznets Curve - Wrenching and Levelling Forces during Agricultural Transformation in Taiwan and Chile

    Detta är en avhandling från Almqvist & Wiksell International

    Författare :Martin Andersson; Lund University.; Lunds universitet.; [2003]
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Chile; Taiwan; initial conditions; agricultural transformation; wrenching and levelling forces; the Kuznets Curve; Economic growth; income distribution; Social and economic history; Ekonomisk och social historia;

    Sammanfattning : What are the effects of growth on equality in a long-term perspective? What are the effects of different patterns of equality on subsequent growth? And why are these questions relevant for the understanding of economic development? These are the overriding questions posed in the dissertation. They are addressed in the context of long-term change from economic backwardness to modern economic growth by examining the processes of agricultural transformation of two successful growth achievers -- Taiwan and Chile.

  4. 3. The Digital Transformation of the Swedish Graphic Industry

    Detta är en avhandling från Institutionen för ekonomisk och industriell utveckling

    Författare :Mathias Cöster; Linköpings universitet.; Linköpings universitet.; [2007]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SOCIAL SCIENCES Statistics; computer and systems science Informatics; computer and systems science Informatics; SAMHÄLLSVETENSKAP Statistik; data- och systemvetenskap Informatik; data- och systemvetenskap Informatik; Economic Information Systems; Ekonomiska informationssystem; IT; Productivity; Industrial transformation; Innovation development; Digitization; Graphic Industry; Development blocks; Technological systems;

    Sammanfattning : This thesis examines how IT and the digitization of information have transformed the Swedish graphic industry. The debate concerning the productivity paradox, i.e. if investments in IT contribute to productivity growth, is one important starting point for the thesis. LÄS MER

  5. 4. Fate of Pharmaceuticals and Their Transformation Products in Rivers An integration of target analysis and screening methods to study attenuation processes

    Detta är en avhandling från Stockholm : Department of Environmental Science and Analytical Chemistry, Stockholm University

    Författare :Zhe Li; Stockholms universitet.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; pharmaceuticals; transformation products; fate; river; suspect screening; non-target screening; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Pharmaceuticals are environmental contaminants causing steadily increasing concern due to their high usage, ubiquitous distribution in the aquatic environment, and potential to exert adverse effects on the ecosystems. After being discharged from wastewater treatment plants (WWTPs), pharmaceuticals can undergo transformation processes in surface waters, of which microbial degradation in river sediments is considered highly significant.

  7. 5. Dynamics of Energy Systems - Methods of analysing technology change

    Detta är en avhandling från Environmental and Energy Systems Studies, Lund university

    Författare :Lena Neij; Lund University.; Lunds universitet.; [1999]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy research; evaluation; market transformation; PV modules; wind power; experience curves; air-distribution; lighting; vintage models; sustainable energy; renewable energy; energy efficiency; Energy; energy system; Energiforskning; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

    Sammanfattning : Technology change will have a central role in achieving a sustainable energy system. This calls for methods of analysing the dynamics of energy systems in view of technology change and policy instruments for effecting and accelerating technology change. In this thesis, such methods have been developed, applied, and assessed. LÄS MER
