  1. 1. Optical remote sensing of industrial gas emission fluxes

    Författare :John Johansson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; DOAS; formaldehyde; optical remote sensing; gas emission; absorption spectroscopy; solar occultation; VOC; flux measurement; FTIR;

    Sammanfattning : Mobile optical remote sensing techniques offer promising possibilities to quantify and geographically attribute local industrial gaseous emissions to the atmosphere. Studies have 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.

  3. 2. Optical remote sensing of industrial gas emission fluxes

    Författare :John Johansson; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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.

  4. 3. Multiobjective Optimization for Safety and Reliability Trade-off : Applications on Early Phases of Aircraft Systems Design

    Författare :Cristina Johansson; Johan Ölvander; Micael Derelöv; John Andrew; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES;

    Sammanfattning : A strategic issue for any industrial company is to conceive safe and reliable systems while performing all systems’ intended functions at a minimum cost. System safety and reliability are fundamental to system design and involve a quantitative assessment prior to system development. LÄS MER

  5. 4. Labour Market Policies : Structure and Content, Space and Time

    Författare :John Brauer; Anders Bruhn; Björn Johansson; Daniel Clegg; Örebro universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Labour market policies; activation; unemployment; multi-level governance; local governance; social work; institutional change; scale;

    Sammanfattning : Labour market policies has two aims: cushioning the economic hardship caused by unemployment and increasing employment rates. In many welfare states, responsibilities for such policies are divided between different political-administrative levels. LÄS MER

  7. 5. The formation of successful physics students : Discourse and identity perspectives on university physics

    Författare :Anders Johansson; John Airey; Maja Elmgren; Kathryn Scantlebury; Ellen Karoline Henriksen; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Physics with specialization in Physics Education; Fysik med inriktning mot fysikens didaktik;

    Sammanfattning : In university physics education, unequal student participation has always been an issue. An example is the fact that men constitute 70–80% of the student body in most countries. LÄS MER
