Identification of Arrays of Cracks in the Elastic Medium by the Ultrasonic Scanning,es measured in the echo method for the full circular interval of the scanning angle. The diffraction of the elastic waves is studied in the scalar approximation. The proposed numerical algorithm is tested on some examples with clusters of cracks whose position and geometry are known a priori.

Short-Wave Diffraction of Elastic Waves by Voids in an Elastic Medium with Double Reflections and Tdiffraction integrals by means of multidimensional stationary-phase method. The novel approach allows us to obtain the leading asymptotic term of the diffracted displacement field as a closed-form expression in the cases of single and double reflections, which corresponds to the geometrical theory of diffraction (GTD).

A smooth way may consist of outsourcing parts of one’s non-core business processes to specialized parties in the market. A variety of outsourcing models have been developed ([6]). Outsourcing can ra
