An inconsistency of science and religion is shown. What is more, a blocking influence of religion to the science is demonstrated by numerous examples. The contents of the article is report material which is submitted for the international symposium 2 - 4 Octobers 2001г. "Science, anti-science, and paranormal belief". Text of the article is placed on www.atheism.ru

Thermodynamic cycles of a perfect and practicable turbo-jet engine are considered. Their features and methods of choice of optimum parameters are analysed. The theoretical means of receiving varied specific tractions and specific spendings of fuel by two-chamber turbo-jet engines are given in this article.

Angular distribution of the angular momentum flux proceeding from a rotating electric dipole is shown to have a maximum in the plane of rotation of the dipole. The conclusion is made about an orbital character of this angular momentum. It is affirmed that, besides this flux, there is a flux directed perpendicularly to the plane the rotation, directed just as a radiation of circular polarization is directed. For a calculation of the flux an expressions which are absent in modern electrodynamics are used. So, it is emphasized that modern electrodynamics is not full.

The article consider of use of sigmoidal function in quality activation function Hopfield network. To draw an analogy between functioning this neural network and homogeneous fuzzy set type k. The efficiency of using Hopfield network with function hyperbolic tangent for reconstruction greatly distortedly pictures is show.

This article presents theoretical analysis of using neural networks for forecasting of parameters, which characteristic the aircraft state based on the results of trajectory measurements. The principle possibility of using this method demonstrates on the results of values of carrier rocket speed.

In given article the description of algorithm of coding of rearrangements with the recurrences, compression of the information being statistical algorithm is submitted. Two variants of a method are examined: two passed, demanding a priori knowledge of statistics of a coded sequence, and one passed, forming statistics during work. It is shown asymptotical an optimality of algorithm at increase of length of a sequence. Dependence of time of coding on length of a compressed sequence is resulted. It is informed practical results of modelling of algorithm on the computer.

The behavior of third order phase-lock loop of navigation receiver in brief miss of signal and fluctuation noise is investigated. Expressions are derived to compute probability of independent acquisition and probability of cycle slip. The way of performance improve have been recommend.
