The current definitions of punctuation commonly met in Russian and English linguistic sources, as well as the communication functions of punctuation marks are discussed.. Much attention is given to the description of the theoretical and practical aspects of punctuation, as well to the main historical treatment of the problem. The common origin and the symmetry of punctuation marks in the main European languages are stressed. All the punctuation marks of the English language and the rules of their functioning are shown. The rules of use of capital letters in the English and Russian writing are set forth.

The article gives a brief characteristic of such notions as the normative phonetics-orthoepy, a language norm and speech norm. It also gives general characteristics of the modern French speaking language and basic tendencies of the modern French pronunciation. The system of exercises for audition used in the Moscow Aviation Institute on the advanced level of teaching French is presented as well.

Field-level electromagnetic radiation with the frequency higher than 10 GHz can cause a response in human brain and central neural system with consequent unconscious mistakes that can be very dangerous in fine professional activity, for example, in aircraft flight control. Investigations were made with the participation of All-Russia Catastrophe Medical Center and special device "Gamma-7N" was developed in order to reduce such danger.

This paper is devoted to parallel-recursive methods of performance of wavelet-transformation for one-dimensional and bidimentional discrete signals. The algorithm of parallel- recursive methods of performance of wavelet-transformation should provide effective processing on parallel systems.

Image feature representation techniques using orthogonal moment functions have been used in many applications for signals processing. Legendre moments are very popular in this technique. In this paper, we introduce a new rotation invariants of Legendre moments based on Legendre polynomials. The moments unchanged for translated, rotated, contracted, reflected and elongated non-symmetrical or symmetrical images. The algorithm is tested on model image.

It is shown that the modern Maxwell electrodynamics cannot explain the result of the Beth experiment. So, the modern electrodynamics is not complete. A spin tensor is used for an explanation of the experiment. It is shown that this tensor completes the Maxwell electrodynamics. A theory of the Beth's experiment is presented.
