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

    Detta är en avhandling från Örebro : Örebro University

    Författare :Sahar Asadi; Örebro universitet.; [2017]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; mobile robot olfaction; time-dependent gas distribution modelling; temporal sub-sampling; sensor planning; artificial potential field; gas monitoring;

    Sammanfattning : 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. LÄS MER

  2. 2. Simulation of Chemical Reactors

    Detta är en avhandling från Örebro : Örebro University

    Författare :Tommy Hertzberg; Lunds universitet.; Lund University.; [1997]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; fluid flow; chemical reactors; formox; fractional step; catalytic combustion; Spectral methods; self-adjoint operator; Chemical technology and engineering; Kemiteknik och kemisk teknologi;

    Sammanfattning : This thesis consists basically of two parts. They are, however, interrelated by the fact that both parts concerns modelling of catalytic reaction systems and also by the fact that in both parts, spectral methods are used for simulation. The first part describes the numerical treatment of the dispersion model. LÄS MER

    Sammanfattning : Fluidized bed technology has been commercially applied over severaldecades. However there is still a lack of knowledge that can provide adetailed understanding of the combustion process in fluidized-bed furnaces. LÄS MER

  5. 5. Change detection in metal oxide gas sensor signals for open sampling systems

    Detta är en avhandling från Örebro : Örebro university

    Författare :Sepideh Pashami; Örebro universitet.; [2015]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; metal oxide sensors; Open Sampling System; change point detection; gas dispersion simulation; environmental monitoring; Datavetenskap; Computer Science;

    Sammanfattning : This thesis addresses the problem of detecting changes in the activity of a distant gas source from the response of an array of metal oxide (MOX) gas sensors deployed in an Open Sampling System (OSS). Changes can occur due to gas source activity such as a sudden alteration in concentration or due to exposure to a different compound. LÄS MER
