  1. 21. Frequency Noise in Coherent Optical Systems: Impact and Mitigation Methods

    Författare :Aditya Kakkar; Richard Schatz; Sergei Popov; Gunnar Jacobsen; Xiaodan Pang; Oskars Ozolins; Magnus Karlsson; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Equalization enhanced phase noise; frequency noise; coherent optical communications; carrier phase recovery; carrier phase estimation; circular quadrature amplitude modulation; EEPN; CmQAM; blind phase search; phase noise;

    Sammanfattning : The increase in capacity demand along with the advancement in digital signal processing (DSP) have recently revived the interest in coherent optical communications and led to its commercialization. However, design and development of robust DSP algorithms for example for carrier phase recovery (CPR) becomes complex as we opt for high order modulation formats such as 16QAM and beyond. LÄS MER

  3. 22. Phase Noise Tolerant Modulation Formats and DSP Algorithms for Coherent Optical Systems

    Författare :Jaime Rodrigo Navarro; Sergei Popov; Gunnar Jacobsen; Richard Schatz; Xiaodan Pang; Oskars Ozolins; Gabriella Bosco; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical communications; carrier phase recovery; blind phase search; circular quadrature amplitude modulation; CmQAM; coherent optical communications; digital signal processing; carrier phase estimation; equalization enhanced phase noise; EEPN; Telecommunication; Telekommunikation;

    Sammanfattning : Coherent detection together with multilevel modulation formats has the potential to significantly increase the capacity of existing optical communication systems at no extra cost in signal bandwidth. However, these modulation formats are more susceptible to the impact of different noise sources and distortions as the distance between its constellation points in the complex plane reduces with the modulation index.

  4. 23. Controlling the Influent Load to Wastewater Treatment Plants

    Författare :Jon Bolmstedt; Industriell elektroteknik och automation; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The need for control of the influent load to a wastewater treatment plant (WWTP) is becoming more important. One reason for this is that there are a number of things that cannot be achieved with plant-focused control. LÄS MER

  5. 24. Underskott i aktiebolag : En skatterättslig studie av förlust- och resultatutjämning i ljuset av svensk rätt och EU-rätten

    Författare :Anna Romby; Mattias Dahlberg; Bertil Wiman; Peter Melz; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Finansrätt; Fiscal Law;

    Sammanfattning : Underskott i aktiebolag. Losses of Limited Liability Companies.The general subject of this thesis is the tax treatment of losses incurred in limited liability companies (aktiebolag) in light of Swedish law and European law. LÄS MER

  7. 25. Understanding didactic strategies based on the Laban-Malmgren technique when developing the technical and musical proficiency of singers

    Författare :Bo Rosenkull; Göteborgs universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; interpretive description; Jung; Laban; Laban-Malmgren technique; Malmgren; movement and singing; participatory action research; self-study; singing technique; Stanislavski; voice pedagogy; Yat Malmgren;

    Sammanfattning : In this thesis multiple methods were used to explore how the use of didactic strategies based on the LMT may enable a voice pedagogue to develop the technical and musical proficiency of singers who specialise in Western art music. Data for this qualitative study were collected by working with fourteen singers in South Africa and Sweden during workshops, masterclasses and individual lessons. LÄS MER
