  2. 16. Towards Dense Air Quality Monitoring : Time-Dependent Statistical Gas Distribution Modelling and Sensor Planning

    Author : Sahar Asadi; Achim Lilienthal; Amy Loutfi; Dominque Martinez; Örebro universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; mobile robot olfaction; time-dependent gas distribution modelling; temporal sub-sampling; sensor planning; artificial potential field; gas monitoring;

    Abstract : This thesis addresses the problem of gas distribution modelling for gas monitoring and gas detection. The presented research is particularly focused on the methods that are suitable for uncontrolled environments. READ MORE

  4. 17. Studies of MISiC-FET sensors for car exhaust gas monitoring

    Author : Helena Wingbrant; Anita Lloyd Spetz; Martin Eickhoff; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; field effect sensor; gas detection; selective catalytic reduction; lambda; cold start; ammonia; silicon carbide; engine exhaust; Physics; Fysik;

    Abstract : The increasing size of the car fleet makes it important to find ways of lowering the amounts of pollutants from each individual diesel or gasoline engine to almost zero levels. The pollutants from these engines predominantly originate from emissions at cold start, in the case when gasoline is utilized, and high NOx emissions and particulates from diesel engines. READ MORE

  5. 18. Development of high temperature SiC based field effect sensors for internal combustion engine exhaust gas monitoring

    Author : Helena Wingbrant; Anita Lloyd-Spetz; Karin Larsson; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; field effect sensor; gas detection; selective catalytic reduction; lambda; cold start; ammonia; silicon carbide; engine exhaust.; Physics; Fysik;

    Abstract : While the car fleet becomes increasingly larger it is important to lower the amounts of pollutants from each individual diesel or gasoline engine to almost zero levels. The pollutants from these engines predominantly originate from high NOx emissions and particulates, in the case when diesel is utilized, and emissions at cold start from gasoline engines. READ MORE
