Rings are made of 9 junctions with 3 different critical currents. We present results for a wide range of the main physical parameters of the system: damping, coupling and temperature. The computed results can be well understood in the framework of single particle thermal activation theories.2015http://zaguan.unizar.es/record/6150310.1140/epjb/e2015-60381-1http://zaguan.unizar.es/record/61503oai:zaguan.unizar.es:61503info:eu-repo/grantAgreement/ES/DGA/FENOL-GROUPinfo:eu-repo/grantAgreement/ES/MINECO/FIS2011-25167European Physical Journal B 88, 7 (2015), 185 [8 pp.]All rights reservedhttp://www.europeana.eu/rights/rr-f/info:eu-repo/semantics/openAccess
