Study error components for solving the inverse problem using random projections / Revunova O.H. // Mathematical Machines and Systems. - 2010. - N 4. - P. 33 - 42.
A comparative analysis of discrete ill-posed inverse problems solutions obtained by discretization of the integral equation (Carasso, Delves, Phillips problems) has been performed. Pseudo-inverse and Tikhonov regularization methods were used. The same technique we used with additional projection by random matrix. The error partitioning into bias and variance was done. The dependence of the components of error solution (bias and variance) on the dimension of the projector matrix was studied. Pseudo-inverse method, when projecting, has shown the accuracy similarly to Tikhonov regularization. Tabl.: 3. Figs.: 9. Refs.: 22 titles.

Biogenetic law of Haeckel and his role in revealing the mechanism of retransmission of natural laws during the process of creation and evolution of computer techniques. Part 2 / Briukhovych Ye.I. // Mathematical Machines and Systems. - 2010. - N 4. - P. 169 - 180.
It was obtained an answer to the question how man creates and evolves computer techniques by natural laws. The answer is contained in the action mechanism of the known Central Dogma of Molecular Biology (CDMB), which there is in the basis of Haeckel's biogenetic law and became a new substantiation of correctness of assertions of this law. Accordingly to the law a short and quick repetition (recapitulation) of the most important stages of evolution of a species (phylogenesis) is taking place by individual development of a person (ontogenesis). In accordance with the CDMB the recapitulation (repetition) is determined by reproducing from RNA a copy of the genetic information, contained in DNA, without destroying an original, as a result in DNA occurs a sequential lamination (accumulation) of genetic information during an all phylogenesis of a species. Conclusion was made that human during process of creation and evolution the computer techniques, not realizing, recapitulates phylogenesis from Homo sapiens to ontogenesis of Computer sapiens.
