  1. 1. Development of New Monte Carlo Methods in Reactor Physics Criticality, Non-Linear Steady-State and Burnup Problems

    University dissertation from Stockholm : Universitetsservice US AB

    Author : Jan Dufek; Jan Wallenius; Waclaw Gudowski; Cheikh Diop; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Monte Carlo; reactor physics; fission source; inactive cycles; convergence; burnup; steady-state; criticality; eigenvalue; NATURAL SCIENCES Physics Nuclear physics; NATURVETENSKAP Fysik Kärnfysik;

    Abstract : The Monte Carlo method is, practically, the only approach capable of giving detail insight into complex neutron transport problems. In reactor physics, the method has been used mainly for determining the keff in criticality calculations. READ MORE

  2. 2. A Transnational Study of Criticality in the History Learning Environment

    University dissertation from Umeå : Umeå University

    Author : Sergej Ivanov; Janet Enever; Rodney Jones; [2016]
    Keywords : HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; criticality; transnational; curriculum theory; policy; upper secondary; history; learning environment; comparative; language teaching and learning; språkdidaktik;

    Abstract : This study examines conceptions of criticality and its instruction in the History learning environ- ment in Sweden, Russia, and Australia as evidenced in one sample upper secondary class in each country. To achieve this, data were collected at macro, micro and meso levels. READ MORE

  4. 4. Development of a Methodology for Detecting Coolant Void in Lead-cooled Fast Reactors by Means of Neutron Measurements

    University dissertation from Uppsala : Acta Universitatis Upsaliensis

    Author : Peter Wolniewicz; Håkansson Ane; Christian Jammes; [2014]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LFR; fission chamber; nuclear; reactor; leak; criticality;

    Abstract : In a lead-cooled fast reactor (LFR), small bubbles (in the order of one mm or less) may enter the coolant from a leaking steam generator. If such a leakage is undetected the small bubbles may eventually coalesce into a larger bubble in local stagnation zones under the active core.

  5. 5. Tangible participation - Engaging designs and design engagements in pedagogical praxes

    University dissertation from Lund University (Media-Tryck)

    Author : Henrik Svarrer Larsen; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Aesthetics; annotated portfolios; Certec; corporeality; critical design; criticality; design; design artefacts; design hermeneutics; design qualities; design research; designerly; disability; embodiment; experiential qualities; extended materiality; hybrid media; ideation; intellectual disability; interaction design; interactivity; multisensory; multisensory environments; MSE; participation; participatory design; probes; programmatic design research; rehabilitation engineering; research by design; research through design; sensuousness; sketching; Snoezelen; tangible computing; tangibles.;

    Abstract : This dissertation contributes to three fields within design research: - Explorations of a design space related to aesthetics of Tangible Interaction, which have led to a set of design imaginations as well as perspectives on salient design qualities. - Views on and a designerly example of knowledge construction related to Research through Design as well as to programmatic approaches to design research.
