Since the beginning of the nineties, the CEA (the French Atomic Energy Commisssion), has been being developing ultrasonic modeling tools dedicated to NDT simulation and, over the years, integrated in the CIVA software platform. The models allow to compute ultrasonic beams generated by transducers in the inspected components, to conceive phased arrays transducers and to predict echoes arising fr...

In this paper, an efficient technique is proposed to manage the cache memory. The proposed technique introduces some modifications on the well-known set associative mapping technique. This modification requires a little alteration in the structure of the cache memory and on the way by which it can be referenced. The proposed alteration leads to increase the set size virtually and consequently t...

OBJECTIVE We assessed the orofacial involvement in JDM, and evaluated the possible association of gingival and mandibular mobility alterations with demographic data, periodontal indices, clinical features, muscle enzyme levels, JDM scores and treatment. METHODS Twenty-six JDM patients were studied and compared with 22 healthy controls. Orofacial evaluation included clinical features, dental a...

The microscopic and geomechanical properties of igneous building stones include the level of alteration, presence of micro cracks, peak strength, porosity, proportion of detrimental minerals, etc. Porosity is reportedly of a devastating impact on the peak strength of igneous rocks. The quartz diorite rock samples in this study were selected from five quarries in Natanz, Iran and subject to micr...

In today’s environment of shrinking resources, and consistent need for accurate inspections, simulation software is an effective cost cutting tool. CIVA is an advanced NDT simulation software dedicated to modeling ultrasonic (UT), radiographic (RT) and eddy current (ET) inspections without the need for physical test sample or inspection equipment. Each inspection module is comprised of simulati...

Since the beginning of the nineties, the CEA (the French Atomic Energy Commisssion), with developing the CIVA NDT expertise platform is greatly involved in the development of simulation tools. Over the years, and with successive versions of CIVA, the results of modeling research work have been being integrated into the software both for ultrasonics and Eddy current techniques. In order to fullf...

Collaboration networks provide a method for examining the highly heterogeneous structure of collaborative communities. However, we still have limited theoretical understanding of how individual heterogeneity relates to network heterogeneity. The model presented here provides a framework linking an individual’s skill set to her position in the collaboration network, and the distribution of skill...
