| Defect identification by flexural component evaluation in guided wave monitoring of pipework using a magnetostrictive sensor F. Bertoncini 11, C. Oprea 4, M. Raugi 12, F.

In this paper, a new method is presented that helps identifying pipe flaws in guidedwave inspection results. It is based on the evaluation of flexural components extracted from data sets acquired with a multitude of magnetostrictive sensors uniformly distributed around the pipe circumference. In addition, to prove its efficiency, the method will be applied to both simulated and experimental data and the results will be compared. Finally the nature of the separated wave modes will be confirmed comparing the experimental wave velocity information to data available in the literature.

Today rubber is due to its unique property profile one of the most important materials for the production of bearings, dampers or also tires and tubes. In the production of rubber goods a chemical cross-linking reaction (vulcanisation) generates the final material properties. This process takes place during the shape giving of the rubber compound in the mould and can proceed for several minutes. The cross-linking process is influenced by the mixture of the basic polymer, the cross-linking agent, the influence of catalysts and inhibitors and especially the processing conditions. The quality of every ingredient, the reproducibility of the mixing ratio, the homogeneity of the mixture and the accurateness in temperature control can have a direct influence on the cross linking reaction. To control the quality of a rubber compound and verify the processing conditions in industry moving die rheometers, named curemeter, are involved in the production process. Starting from our experience in cure monitoring of thermosetting materials by measuring ultrasound velocity in the mould we extended the measuring principle to rubber vulcanisation monitoring. After first investigations using a compression mould we dealt here with on-line monitoring of vulcanisation in an injection moulding process which is one of the most
used techniques in rubber industry.

| Nondestructive Insights into Composition of the Sculpture of Egyptian Queen Nefertiti with CT and the dependence of object surface from image processing B. Illerhaus 29 , A. Staude 28, D.

Precautions in the generation of surfaces from CT images should be the rule. Two different data sets of the bust of Nefertiti and additional data from an industrial CT scanner will show the conflicts that arise when defining a surface. The recent trend in CT is to extract surfaces from CT measurements which can compete with the accuracy of tactile measurements. As CT is complicated by artefacts, a lot of precautions need to be taken in order to get exact results. More errors are introduced, if the surface of an object made from different dense materials is calculated. A publication in April 2009 of ?Radiology?[9] dealt with the surface of the stone behind the stucco layer of the famous bust of the Egyptian Queen Nefertiti in the Ägytische Museum Berlin. Using this data, we will show the different problems that arise from inadequate image processing. Furthermore, a detailed comparison of the two CT measurements made 14 years apart is given. Conclusions: Respect the traps in virtual imaging.
