  2. 1. Conservation of landlocked Atlantic salmon in a regulated river : Behaviour of migratory spawners and juveniles

    Author : Anna Hagelin; Eva Bergman; Fleming Ian; Karlstads universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Atlantic salmon; conservation; migration; spawning; hydropower; competition; juveniles; brown trout; hatchery reared; fallback; delay; Biology; Biologi;

    Abstract : Hydropower dams represent one of the major threats to river ecosystems today. The dams block migratory routes in many rivers, which is problematic for migratory fish species. Trap-and-transport may be an alternative to fish passage solutions, as a strategy to compensate for lost river connectivity. READ MORE

  4. 2. On Enhancement and Quality Assessment of Audio and Video in Communication Systems

    Author : Andreas Rossholm; Blekinge Tekniska Högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; QoE; video quality assessment; video quality metric; multi-linear regression; artificial neural network; support vector machine; quality predictor; machine learning; temporal scaling; spatial scaling; video compression; deblocking filter; noise cancelling; synchronization; audio delay; video delay; GSM interference signal; noise cancellation; notch filtering;

    Abstract : The use of audio and video communication has increased exponentially over the last decade and has gone from speech over GSM to HD resolution video conference between continents on mobile devices. As the use becomes more widespread the interest in delivering high quality media increases even on devices with limited resources. READ MORE

  5. 3. Contributions to Delay, Gain, and Offset Estimation

    Author : Mattias Olsson; Håkan Johansson; Per Löwenborg; Markku Renfors; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; time interleaved analog to digital conversion; delay estimation; OFDM; fractional delay filters; Signal processing; Signalbehandling;

    Abstract : The demand for efficient and reliable high rate communication is ever increasing. In this thesis we study different challenges in such systems, and their possible solutions. READ MORE

  6. 4. Quality aspects of audio communication

    Author : Ian Marsh; RISE; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : The Internet is increasingly being used to carry real-time voice traffic. Users of real-time voice services are sensitive to variable audio quality. The quality of packet audio is largely determined by the mouth-to-ear delay and the packet loss. READ MORE

  7. 5. Stereophonic Acoustic Echo Cancellation: Theory and Implementation

    Author : Peter Eneroth; Institutionen för elektro- och informationsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Stereophonic Acoustic Echo Cancellation; Filterbank; Two-Channel Fast RLS; Two-Channel Frequency-Domain Adaptive filtering; NLMS; Electronics and Electrical technology; Audio Coding; Elektronik och elektroteknik; Signal processing; Signalbehandling; Subband;

    Abstract : The thesis treats theory and implementation aspects for stereophonic acoustic echo cancellation. In Paper I a complete implementation of a stereophonic acoustic echo canceler based on the two-channel fast recursive least-squares algorithm is presented. READ MORE
