The work is dedicated to the method of threshold separation of digital data, based on the use of bit masks, and evaluated the possibility of its use in the divided transmission data. According to the data split transmission scheme the sender divides the original data into several parts which are independently transmitted via various communication channels, and the receiver reconstructs the original data from parts transmitted. The split transmission can be used to increase the speed of communication or its reliability, as well as to ensure the privacy of transmitted data due to the complication of the problem of interception of multiple communications channels. The requirements for the threshold methods of data sharing for their use in the split transmission are formulated the correspondence between the bit masks method and the advanced requirements is analyzed. An algorithm for using the bit masks method for transferring confidential information in a split transmission system is developed.

Web application building is used in implementation of different systems and tools when users need to be able to work at a distance using different computers. Training control tools where mainstream users are students and teachers participating in e-learning and blended learning are one of these tools. There are different types of web application building methods which have some advantages and disadvantages according to a set of criteria. A problem of multicriterion choice of the optimal solution occurs when choosing the web application building method for implementation of training control tool. Three web application building methods such as: method based on using compiled and compiled-interpreted language, method based on using interpreted script language and method based on using content management system and content construction kit are determined in the paper. A set of basic criteria including: web application building simplicity, web application building speed, experiences and support was defined. Analytic hierarchy process was used in choosing the optimal web application building method. The method allowed defining optimal web application building method for implementation of training control tool: method based on using interpreted script language.

The method is considered for seaching a single-phase or three-phase electricity meter with the radio control module installed in it. With the help of this module, the consumer of electric energy has the opportunity to disconnect the pecking motor of the electric meter. These actions are allow you not take into consideration actually consumed elecrtrical energy. This module is installed by the consumer illegally and when a network organization detects this , they make an act about unaccounted electric power consumption. The method is based on the measurement of the intaking power of the volt circuit by the maser gage CE601 of the analyzing counter of electrical power CE 101, with the mechanical counting mechanism. Herewith, the consumer's loading is switched off by supply feeders. This method is allow to draw the conclusions about the presence of embedded non-factory devices without disconnecting of the electricity meter from the network ( time saving ).

The paper considers the optimization of technological process of manufacturing of the coils of the steam generator based on the concept of lean manufacturing. The analysis of the manufacturing process of the coils revealed problems: the yield of the pipe after conversion of the bending machine, large inventory of finished tubes, stored on the stocks vertical storage (racks), loss of time for travel, due to the placement site of flexible pipes in different spans, continuous changeover. To solve these problems were applied the principles of lean production. As a result of the optimization was able to reduce WIP 70%, to reduce logistics and remoteness of workplaces in the production flow by 10 times, reduce the time of processes for the conversion of 2 times, to reduce the risk of traces of mechanical damages on the surface of the coils.

In the article, we considered the actual problem of constructing an algorithm based on the interaction of parallel components. The paper contains elements of the methodology developed by the authors for the parallel functioning of algorithms based on graph theory. It is shown that the construction of an algorithm with parallel functioning of components is impossible without taking into account the time, for which the concept of a time axis was introduced, and the sequential algorithm is represented in the form of a bipartite graph by its additional definition. The methods of parallel algorithms represented in the article, realized as dual graphs or matrix predicate form, make it possible to use them in describing complex control and measuring systems. It is concluded that the advantage of such a representation of the parallel functioning of algorithms lies in the fact that it becomes possible to work with parallel hierarchical structures, tracing the changes in each of them by means of input time axes.

The paper presents a numerical study of the effect of external electromagnetic fields of various configurations on the computer model of a neuron; Briefly describes the created software product, allowing to conduct numerical simulation of nerve cells, the mechanism of conduction of the nerve impulse. In an alternating field, the ion flux behaves as follows: at frequencies below 1 kHz, 3 maxima of the function of the average ion velocity are observed: these are 82 Hz, 340 Hz and 801 Hz. Under the influence of fields of higher frequencies from 1 kHz to 900 kHz, strong changes in velocities and currents do not occur. It is possible that in this frequency range the field does not have time to change the velocity modulus, but at a frequency of 970 kHz there is a sharp increase in the average ion velocity, which is most likely related to the effect of the myelin sheath, since no maximum is observed from the myelin sheath.
