The Boundary Element Method for Inverse Problems in NDE
Model-based quantitative nondestructive evaluation (QNDE) can be cast as an inverse problem, in which the geometry or mechanical properties are the unknowns of a mechanical problem given its response as the provided data. The benefits of using boundary integral equation methods for the model are the boundary-only dependency, the accuracy in fracture mechanics and the computation speed for high frequency waves. An overview of the possibilities and techniques that these concepts provide are presented here, as well as some theoretical and experimental applications.

Investigation of Gasdynamic Characteristics of Compressors Cascades
In the phase of preliminary compressor design it is very important to know gasdynamical variables inside its blade passages. In addition from the economical and stability point of view it is very important to know these variables at different exploitation regimes, and to know performance maps of turbocompressor. Most experimental methods concerning the investigation of flow throughout compressor blade passages are very expensive. Within the scope of presentation the numerical algorithm for simulation of complex three-dimensional viscous flow throughout compressor blade passages will be presented. Numerical simulations at different flow regimes namely at different number of rotation and mass flow rates were used to predict compressors‘ performance maps.
