  2. 16. Cross-Correlator Implementations Enabling Aperture Synthesis for Geostationary-Based Remote Sensing

    Author : Erik J Ryman; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; full-custom; signal processing; synthetic aperture; Cross-correlation; interferometric imaging; ASIC; remote sensing;

    Abstract : An ever-increasing demand for weather prediction and high climate modelling accuracy drives the need for better atmospheric data collection. These demands include better spatial and temporal coverage of mainly humidity and temperature distributions in the atmosphere. READ MORE

  4. 17. A Cross-Correlator for the Remote Sensing of Earth by Synthetic Aperture

    Author : Erik J Ryman; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cross-correlation; synthetic aperture; ASIC; VLSI.; earth observation;

    Abstract : In light of our changing climate and the unpredictability of severe weather; a better understanding of our climate and increased weather forecast accuracy are in high demand. Humidity and temperature distribution profiles with high temporal resolution can significantly increase our knowledge of highly dynamic weather phenomena and improve weather forecasts. READ MORE

  5. 18. 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

  6. 19. Properties of heavy rainfall in an East Asian monsoon catchment - Analysis of daily rain gauge data

    Author : Cecilia Svensson; Avdelningen för Teknisk vattenresurslära; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; China.; Huai River; East Asian monsoon; typhoon; Mei-Yu front; fractals; empirical orthogonal function analysis; correlation analysis; probable maximum precipitation; storm movement; seasonal occurrence; Rainfall; spatial pattern; Hydrogeology; geographical and geological engineering; Hydrogeologi; teknisk geologi; teknisk geografi; Geophysics; physical oceanography; meteorology; Geofysik; fysisk oceanografi; meteorologi;

    Abstract : The East Asian monsoon has a strong seasonal effect on the rainfall regime of Eastern China. In order to mitigate floods and conserve the water for use throughout the year, dams and other hydro-structures are built. The design of the structures requires knowledge of the rainfall characteristics that influence the inflow to them. READ MORE

  7. 20. Steady state analysis of HVDC grid with Wind Power Plants

    Author : Kalid Yunus; Chalmers tekniska högskola; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; ARIMA; electricity price; meshed HVDC grid; WPP; transmission tariff; temporal and spatial correlation; electricity market; VSC HVDC; wind speed modelling; secondary supervisory controller; LRMC; SRMC; PV; primary controller; investment cost;

    Abstract : The idea of building a multi-terminal, even a meshed HVDC grid in the North Sea, that can inter-connect surrounding nations, is being discussed widely. Such a system is expected to be realised in steps through the interconnection of wind power plants and electricity markets. READ MORE
