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

    Abstract : 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. READ MORE

  3. 3. 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; Uppsala universitet.; [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. Three Aspects of Real-Time Multiprocessor Scheduling: Timeliness, Fault Tolerance, Mixed Criticality

    University dissertation from Chalmers University of Technology

    Author : Risat Mahmud Pathan; Chalmers tekniska högskola.; Chalmers University of Technology.; [2012]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Real-Time Systems; Sporadic Tasks; Fixed Priority; Global Multiprocessor Scheduling; Time Redundancy; Fault-Tolerant Scheduling; Mixed-Criticality Systems;

    Abstract : The design of real-time systems faces two important challenges: incorporating more functions/services on existing hardware to make the system more attractive to the market, and deploying existing software on multiprocessors (e.g., multicore) to utilize more processing power. READ MORE
