... The problem of search of the permutations that the corresponding mapping becomes nonstrict close-to-convex appears. The search of set of permutations reducing the integral to nonstrict close-to-convex one consists of three stages: 1) linear programming problems series solution; 2) finding in complete graph the Hamiltonian circuit passing through distinguished sets of sub-paths; 3) recognition in the group of permutations a residue class corresponding to the Hamiltonian circuits set. ...
... Second Harmonic Field of Nonuniformly Vibrating Transducer . ... The second harmonic field can be calculated if the normal velocity distribution (NVD) along a vibrating surface is known. ... The novel recently developed method for accurate evaluation of the NVD along the vibrating surface of a piezoceramic transducer in liquid is presented here. ... The second harmonic field then is simulated based on both the reconstructed NVD and the uniform distribution. ...
