  2. 1. On Performance of Digital Radio Receiver in Non-Gaussian Interference

    Author : Kia Wiklundh; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; bandwidth conversion; performance estimation; APD; interference; minimum shift keying; man-made noise; Gaussian approximation; measurement; emission requirements; non-Gaussian interference; micro-wave oven; MSK; amplitude probability distribution; emission;

    Abstract : Interference from electrical equipment can degrade a co-located digital radio receiver severely. To avoid this performance degradation it is necessary to have estimation methods to predict the influence from an interference environment on a radio receiver in advance. READ MORE

  4. 2. A new approach for considering the interference impact on digital radio systems from complex interference environments

    Author : Kia Wiklundh; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; minimum shift keying; class A; amplitude probability distribution; bandwidth conversion; Gaussian approximation; emission; non-Gaussian interference; performance estimation; man-made noise; measurement; emission requirements; micro-wave oven; MSK; coding gain; APD; interference;

    Abstract : Interference from electrical equipment can severely degrade aco-located digital radio receiver. To avoid such performance degradation, it isnecessary to have estimation methods to predict the influence of an interferenceenvironment on a radio receiver. READ MORE

  5. 3. Air Pollution from Ships - Emission Measurements and Impact Assessments

    Author : Hulda Winnes; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fuel; air pollution; ships; impact assessment; emission measurement; ship emissions; emission inventory; manoeuvring ships; abatement;

    Abstract : Environmental impact and air pollution from ships have received increasing attention the last decades. Due to combustion characteristics of typical marine engines and a wide spread use of unrefined fuel, the global fleet emits significant amounts of SO2, NOX and particles to air. READ MORE

  6. 4. Optical remote sensing of industrial gas emission fluxes

    Author : John Johansson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; optical remote sensing; DOAS; gas emission; absorption spectroscopy; VOC; flux measurement; solar occultation; FTIR; formaldehyde;

    Abstract : Mobile optical remote sensing techniques offer promising possibilities to quantify and geographically attribute local industrial gaseous emissions to the atmosphere. Studies have repeatedly shown that such emissions are often poorly understood, underestimated, and thereby not properly accounted for in emission inventories and regional atmospheric chemistry models, especially for emissions of VOCs.
