The Unified Process (UP) is expected to become one of the leading methods for software engineering with the UML, but although it has a well-defined approach to testing, it has no consolidated strategy for inspection. This paper addresses this problem by describing how the latest inspection technologies can be integrated with the UP in a way that provides an optimal synergy with testing, and rem...

The inspection of various structures often detects a fatigue cracks developed during long service life. These fatigue cracks significantly reduce remaining fatigue life and fatigue strength. Influence of the initial fatigue cracks size in non-load-carrying fillet-welded one-sided transverse attachment joints on the remaining fatigue life and fatigue strength is considered in this paper. A compu...

We report the first stage of a project aimed at computing visibility scripts for active inspection applications, in which a robot-mounted sensor observes a known object from different viewpoints. Visibility scripts describe the optimal sensor position for a given inspection task and may involve different visibility requirements, e.g. achieving optimal visibility of a single object feature or si...

Here we examine an active redundant system with scheduled starting times of the units. We assume availability of n non-identical, non-repairable units for replacement or support. The original unit starts its operation at time s1 = 0 and each one of the (n 1) standbys starts its operation at scheduled time si (i = 2, . . .,n) and works in parallel with those already introduced and not failed bef...
