The author pioneers to study a special class of the grouped hyperplane distributions — the H(, L)-distribution of affine space. He introduces Bompiani — Pantazi correspondences associated with the main structural subbundles of the H(, L)-distribution of affine space. Norden’s normalizations of the main structural subbundles in the differential 1st and 2nd order neighbourhoods of H(, L)-distribution are constructed.

Modern education requires different approaches to improving the efficiency of services for citizens in the public information centers. The article focuses on the methodology for a queue processing and, in particular, on automatic query distribution. The authors developed a system of management quality assurance.

The study of signals with quadrature-amplitude modulation is an urgent task due to their wide application in the satellite television broadcasting systems, as well as for the communication channel of the INMARSAT satellite communication system and the Sirius satellite. The paper presents the results of a study, when an experimental facility was assembled to assess the probability of receiving bit error for a QAM-8 radio signal, depending on the type of signal constellation for different SNRs in the MathLAB + Simulink simulation environment. The results of the research, as well as the developed experimental facility, will be used in the comparative assessment of noise stability of the radio communication channel using standard and prospective patented information transmission systems within the maritime mobile service when receiving radio signals with QAM modulation.

The purpose of this work was to summarize the existing experience and approaches to software development and create the methodology for a software product development for the aviation industry. The current research was based on the systemic analysis and the theory of statistical estimation. This work primarily deals with theoretical methods of research which were used to identify approaches to the mathematical description of atmospheric phenomena models of wind shear, turbulence. The author also analyses relevant the optimal methodology (Russian and foreign papers) for developing software products which takes into account the authors own experience obtained in the process of work at the Russian aerospace industry enterprises.

The method of closed chains of discrete symmetries is used to multiply Toda lattices in one and two spatial dimensions. Using the modified Toda equations m0TCand m1TC as an example, it is shown that the combination of the Darboux and Schlesinger transformations leads to closed dressing chains.
