  1. 11. Gas Sensing Based on Ellipsometric Readout : Methodology and Development

    Författare :Guoliang Wang; Herbert Wonneester; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : The concept of an ellipsometric sensor array system - "an optical nose" - is presented. The system is used to monitor and discriminate gases. The optical readout is based on polarizer-compensator-sample-analyzer (PCSA) off-null ellipsometry. LÄS MER

  3. 12. On interference suppression techniques for communication systems

    Författare :Hongxia Zhao; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; CDMA; QPSK; fixed-point implementation; DQPSK; rapid single flux quantum RSFQ ; MUD; unequal BER; fiber-optic communications; unequal SER; ISI;

    Sammanfattning : The work presented in this thesis concerns interferencesuppression techniques in two different communication systems.In the first part we study fiber-optic systems with practical non-ideal transmitters and receivers, which give rise to intersymbol interference (ISI). LÄS MER

  4. 13. Behavioural differences and genetic relationships between four captive populations of red junglefowl (Gallus gallus) : possible implications for conservation

    Författare :Jennie Håkansson; Linköpings universitet; []
    Nyckelord :Red junglefowl; behavioural differences; genetic relationships; captive populations; NATURAL SCIENCES; NATURVETENSKAP;

    Sammanfattning : Conservation of species is to a large extent carried out by zoos where animals are kept in small populations under protected conditions. The ultimate goal of such ex situ conservation programs is to eventually reintroduce the animals into natural habitats to provide support for the survival of the species. LÄS MER

  5. 14. Hybrid Built-In Self-Test and Test Generation Techniques for Digital Systems

    Författare :Gert Jervan; Zebo Peng; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; system-on-chip; test generation; BIST; hybrid BIST; high-level test; Datavetenskap; Computer science; Datavetenskap;

    Sammanfattning : The technological development is enabling the production of increasingly complex electronic systems. All such systems must be verified and tested to guarantee their correct behavior. As the complexity grows, testing has become one of the most significant factors that contribute to the total development cost. LÄS MER

  7. 15. Locus specific DNA methylation in human immunological responses

    Författare :Emma Ahlén Bergman; Karolinska Institutet; Karolinska Institutet; []
    Nyckelord :;

    Sammanfattning : All cells in the human body contains the same genome. Yet, there are hundreds of different cell types, with widely different phenotype, and function. The differential gene expression leading to this diversity is tightly regulated by epigenetics, i.e. LÄS MER
