  1. 1. Optics for Earth Observation Instruments

    Författare :Arvid Hammar; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; off-axis; free-form mirrors; measurements; stray light; spline horns; THz; reflector optics; satellites; scientific instruments; diamond turning; tolerancing; telescopes;

    Sammanfattning : The optical system is an essential part of every remote sensing instrument used for detecting electromagnetic waves. Careful design, fabrication and characterization is therefore crucial, especially for satellite-borne missions where the possibility of post-launch repairs is highly limited. LÄS MER

  3. 2. Choosing environmental policy instruments : Case studies of municipal waste policy in Sweden and England

    Författare :Åsa Maria Persson; Stockholms universitet; []
    Nyckelord :municipal waste policy; environmental policy instruments; environmental policy; Sweden; England;

    Sammanfattning : European governments have during the last couple of decades shown an interest in new types of environmental policy instruments (EPIs) such as environmental taxes, tradable permit schemes and voluntary approaches, as opposed to relying on traditional forms of regulation. The interest in so-called ‘new’ EPIs (NEPIs) has led many governments to commit both to a more diverse EPI mix and to a policy process characterised by procedural rationality, in terms of considering a wide range ofalternative instruments and assessing them in a systematic and transparent way.

  4. 3. Liksom ett par nya ögon. Frithiof Holmgren och synsinnets problematik

    Författare :Jan-Eric Olsén; Avdelningen för idé- och lärdomshistoria; []
    Nyckelord :HUMANIORA; HUMANITIES; history of ideas; History of philosophy; vivisections; colour perception; colour-blindness; the visual organ; the human body; sensations; scientific ideals; industrial technology; Frithiof Holmgren; scientific instruments; physiological experiments; laboratory medicine; physiology; Filosofins historia; idéhistoria; History of science; Vetenskapshistoria;

    Sammanfattning : This study deals with research on the visual organ as pursued in experimental physiology during the latter half of the nineteenth-century. In the 1850's och 60's experimental physiology developed as a new, scientific discipline within the curriculum of western medicine. LÄS MER

  5. 4. Making Meteorology : Social Relations and Scientific Practice

    Författare :Mikaela Sundberg; Árni Sverrisson; Steven Yearley; Stockholms universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; scientific practice; social worlds; meteorology; climate research; Sociology; Sociologi;

    Sammanfattning : This thesis is about the production of knowledge in meteorological research. Meteorology is an interesting case because of its crucial role in defining the climate change problem, but also because of its reliance on simulation modeling, a comparatively little studied scientific practice.

  7. 5. Precision measurement instruments for machinery's mechanical compliance: design and operation : Measurement instruments for physics-based calibration of advanced manufacturing machinery

    Författare :Nikolas Alexander Theissen; Andreas Archenti; Alexander Slocum; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Measurement instruments; Machine tools; Industrial robots; Production Engineering; Industriell produktion;

    Sammanfattning :  Precision Measurement Instruments (PMIs) for machinery’s mechanical compliance are tools to quantify mechanical load as well as length for measurement ranges of 0.1 µm to 10 m at uncertainty levels of 0.1 µm to 100 µm while exerting mechanical loads. LÄS MER
