Computer methods and inverse problems in nondestructive testing and diagnostics (CM NDT-95) Proceedings

During the past few years it was clearly understood that the future qualitative step in the development of Non-Destructive Testing Technology will be closely connected with enhancement of its quantitative representation and computer fitting. With a growing interest we watch for fast computerization of leading research centres on NDT and there is no doubt that tomorrow this tendency will become daily occurrence of the industry. From simple calculation for signal processing to neural network and artificial intelligence - it is state of the art in development of NDT technique. This trend in strongly stands in need of new ideas and non-typical approaches. Sometimes they as well stand apart of mathematic and computer sciences but require new physical research and attract new physical ideas. The inverse problems are the most noticeable confirmation of this point of view. The correct mathematical formulation of direct problem having its source of physical view on the problem under solution is the main step to solve the inverse one. The inversion seems to be fundamental part of NDT technique in general due to the nature of NDT measurements which are usually indirect one. Fast mathematization and computerization are also caused by necessity of simulation of NDT processes, signal and image processing, data representation, identification of objects under test, data and image reconstruction etc. The basic knowledge in this area is very general for all NDT methods in which up now it is arbitrary scattered. The Conference CM NDT-95 is the first attempt to promote the interaction between scientists, engineers, applied mathematicians and numerical analysts interested in the development and application of computer methods and inverse problems in NDT.
