    Författare :Erik Börjeson; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Adaptive Equalization; Carrier Phase Recovery; Digital Signal Processing; Application-Specific Integrated Circuits; Communication Systems; Fiber-Optic Communication;

    Sammanfattning : The digital signal processing (DSP) circuits used in the fiber-optic communication links that make up the backbone of the Internet can be a significant contributor the over-all power dissipation of a link. As the number of connected users and their bandwidth requirements are expected to continue to grow over the coming years, the development of power-efficient high-throughput DSP systems is a critical factor in enabling this growth.

  3. 2. Implementation of Carrier Phase Recovery Circuits for Optical Communication

    Författare :Erik Börjeson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Communication Systems; Digital Signal Processing; Energy efficiency; fiber-optic communications; Application-Specific Integrated Circuits; Carrier Phase Recovery;

    Sammanfattning : Fiber-optic links form a vital part of our increasingly connected world, and as the number of Internet users and the network traffic increases, reducing the power dissipation of these links becomes more important. A considerable part of the total link power is dissipated in the digital signal processing (DSP) subsystems, which show a growing complexity as more advanced modulation formats are introduced.

  4. 3. Socialsekreteraren och det familjehemsplacerade barnet : Om relationen, erkännandet och de institutionella förutsättningarna

    Författare :Robert Lindahl; Anders Bruhn; Erik Flygare; Martin Börjesson; Örebro universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; foster care; foster child; child welfare worker; social services; relationship; institution; role; professionalism; discretion; recognition;

    Sammanfattning : The aim of this thesis is to study, analyze and understand the relationship between children and youth in foster care and their responsible child welfare workers. The empirical material consists of qualitative interviews with foster children (n=53, three interviews/child, in total 159) and child welfare workers (n=17) conducted in a national evaluation of a pilot project with supervision representatives, and two focus groups conducted for the thesis.
