  1. 1. A Conceptual Model for Analysis of Automation Usability Problems in Control Room Settings

    Författare :Jonas Andersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; Human-machine systems; control rooms; cognitive systems engineering; nuclear power; levels of automation; usability problems;

    Sammanfattning : The focus of this licentiate thesis lies on the problems that can emerge when humans and advanced control systems work together in control room environments. In the nuclear domain, automation is used extensively and it is important to maintain safe and efficient operations. LÄS MER

  3. 2. Representing human-automation challenges

    Författare :Jonas Andersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; human-machine systems; control rooms; cognitive systems engineering; automation;

    Sammanfattning : Automation technology is widely implemented in process control domains due to its benefits of improving efficiency and enhancing control. However, use of automation also introduces an often complex intermediary between the human and the controlled domain, which can obscure from the operator how system functioning is achieved. LÄS MER

  4. 3. Deactivation of diesel oxidation catalysts

    Författare :Jonas Andersson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Accelerated aging: Diesel exhaust: Oxidation catalyst: Sulfur deactivation: Phosphorous poisoning: CO oxidation: Pt dispersion: Al2O3: Sintering: TEM: XPS;

    Sammanfattning : To meet the demand for heavy- and light-duty diesel vehicles on expansive markets while complying with current and future emission standards, it is necessary to reinsure the long-livety of the applied exhaust aftertreatment technology. Loss of catalytic performance may be associated with environmental as well as economical consequences. LÄS MER
