... Ultrasonic Doppler Imaging of Nonlinear Elastic Shear Properties of Biological Tissue Phantoms . ... On the base of the ultrasonic pulsed Doppler technique the software-hardware complex has been built for imaging the forced vibration displacements within phantoms of biological tissues. ... Possibilities are provided by the complex software to record the magnitude distributions of the first and the second harmonicas of this signal in the sample along the ultrasonic beam. ...

... Introduction, image recognition problem 2. ... The first security application 6. ... We use, at first, as the training sample, the following set (see fig. below): [pic] The RBF neural network with L2 -metrics after training on this small set was enabled to recognize without errors specially distorted faces from the same set (see the next picture) [pic] However, as soon as we decided to apply our RBF net to 400 images set from the famous Cambridge face database, our neural net began to mix up faces. ...

... Basic statement: "Mathematics is much clever, than Mathematician" It means, that after the scientist or engineer developed new mathematical model and designed corresponding equations, the solution to these equations produces new information unpredictable for the author! ...
