The main purpose of this paper is to give an overview on the state of the art of inspection, assessment and maintenance of masonry arch railway bridges by the presentation of the results of an ongoing international research project run by the International Union of Railways (UIC) with the participation of 14 railway administrations. The survey has shown that the European railways partaking in t...

The approach of the European Medicines Agency (EMEA) to good laboratory practice (GLP) inspections in the context of authorization of medicinal products is illustrated with particular reference to the EMEA's experience as a receiving authority (RA), the procedures it has in place for the reporting and follow-up of GLP inspections, and the role of the ad hoc GLP inspectors working group. Other k...

The vulnerability assessment of existing masonry buildings is a largely investigated research topic with some aspects still to be faced. In historic towns, are aggregated and together confined, their final appearance derived from interventions additions during lives in different times textures or construction materials. Demolitions reconstructions parts were frequent, the difficulty now underst...

Each engineering decision is based on a number of more or less accurate information. In assessment existing structures, additional relevant information collected with on-site inspections facilitate better decisions. However, observed data basically represents the physical characteristic interest an uncertainty. This uncertainty measure inspection quality and can be quantified by expressing meas...

Experts responsible for the safety evaluation of unique masonry heritage structures usually need to weigh information from various diagnosis activities before deciding best course action preservation. Typical sources valuable are historical and in situ surveys inspections, minor non-destructive testing, structural health monitoring, analysis, among others. Due complexity problem singular aspect...

Hidden corrosion remains a significant problem during aircraft service, primarily because of difficulties in its detection and assessment. The non-destructive D-Sight testing technique is characterized by high sensitivity to this type damage an effective sensing tool for qualitative assessments hidden structures used numerous ground service entities. In paper, the authors demonstrated new appro...
