Reliability and economic analysis of 2-out-of-3 redundant system with priority to repair

  Two reliability models have been developed to compare some reliability and economic measures for a 2-out-of-3 redundant system having two original units (called standard units) and one duplicate unit which areinitially taken as spare in cold standby. The system is considered in up-state if any two of original and/or duplicate units are operative in parallel mode. The original unit is inspected at its...

Curve concentration for a singularly perturbed Neumann problem in three dimensional domain

In this paper we consider the following problem  where  is a bounded domain in  with smooth boundary,  is a small parameter,  denotes the outward normal of  and . Let  be a straight line intersecting with  at exactly two points. We will prove the existence of a solution  possessing curve concentrating set near , exponentially small in  at any positive distance from the...
