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

    Detta är en avhandling från Stockholm : Universitetsservice US AB

    Författare :Jan Dufek; KTH.; [2009]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

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

    Detta är en avhandling från Umeå : Umeå University

    Författare :Sergej Ivanov; Umeå universitet.; [2016]
    Nyckelord :HUMANIORA; HUMANITIES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; language teaching and learning; språkdidaktik; criticality; transnational; curriculum theory; policy; upper secondary; history; learning environment; comparative;

    Sammanfattning : BakgrundAtt kunna vara kritisk är ett förväntat studieresultat i ämnet historia på gymnasienivå i Sverige, Ryssland och Australien. Genom att lära sig om sitt lands och världens historia i klassrummet skapar elever en nationell identitet. LÄS MER

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

    Detta är en avhandling från Uppsala : Acta Universitatis Upsaliensis

    Författare :Peter Wolniewicz; Uppsala universitet.; [2014]
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; LFR; fission chamber; nuclear; reactor; leak; criticality;

    Sammanfattning : 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.

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

    Detta är en avhandling från Lund University (Media-Tryck)

    Författare :Henrik Svarrer Larsen; Lund University.; Lunds universitet.; [2015]
    Nyckelord :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.;

    Sammanfattning : 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.

  5. 5. Thinking with Performance : Research-Based Aesthetics in Times of Conflict and Crisis

    Detta är en avhandling från Lund University (Media-Tryck)

    Författare :Sofie Lebech; Lund University.; Lunds universitet.; [2019-05-20]
    Nyckelord :HUMANIORA; HUMANITIES; Researchbased performance; Torture; Terror; Autoimmunity; Therapy; Performance art body art; live art; happenings ; Aesthetics and ethics; Documentary; affect theory; Criticality; artistic research; Practicality;

    Sammanfattning : Thinking with Performance: Research-Based Aesthetics in Times of Conflict and Crisis is an artistic research project in which I examine how to critically think with performance. My main thesis is that research-based performance uses research to respond to conflict and crisis and to create spaces for thinking where artist and audience can reflect on the represented material.
