    Sammanfattning : Information Systems Engineering (ISE) is an interdisciplinary approach to enable the realisation of successful information systems in a broad sense. ISE comprises a number of areas of expertise that must be integrated and managed in order to build information systems. LÄS MER

  5. 24. Gas discrimination for mobile robots

    Författare :Marco Trincavelli; Amy Loutfi; Silvia Coradeschi; Alcherio Martinoli; Örebro universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TECHNOLOGY; TEKNIKVETENSKAP; Information technology; Informationsteknik; Computer science; Datavetenskap; Computer and Systems Science; Data- och systemvetenskap;

    Sammanfattning : The problem addressed in this thesis is discrimination of gases with an array of partially selective gas sensors. Metal oxide gas sensors are the most common gas sensing technology since they have, compared to other gas sensing technologies, a high sensitivity to the target compounds, a fast response time,they show a good stability of the response over time and they are commercially available.
