  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

    Abstract : The last decades have shown a great need for vocational rehabilitation due to high levels of absenteeism due to sickness and disability pension. An essential part of the vocational rehabilitation process is assessment of persons with reduced work functioning. READ MORE

  3. 3. Reading bones : Stone Age hunters and seals in the Baltic

    University dissertation from Stockholm : Stockholms universitet

    Author : Jan Storå; Jan Ekman; [2001]
    Keywords : HUMANIORA; HUMANITIES; Epiphyseal fusion; Harp seal; Marine mammals; Neolithic; Pitted Ware culture; Ringed seal; Seal hunting; Seasonality; Taphonomy; arkeologi; Archaeology;

    Abstract : This is a study of hunters and seals in the Stone Age in the Baltic. The ambition has been to develop and utilize methods for osteological analyses of archaeological seal bones. The main aims of the zooarchaeological analyses have been to study seal hunting strategies and the formation processes of the faunal remains. READ MORE
