 Abstract
 Problem statement and specific task. The Problem of increasing the efficiency of the use of the power of a propulsion electric motor (PЕM) in the operation of ships in ice conditions is one of the aspects of solving the complex problem of ensuring the safety and resource saving requirements for the operation of marine transport in the Arctic. Given that the ice impact on the ship is stochastic and difficult to predict, the problem of increasing the efficiency of the use of power of PЕM can be solved by providing the skipper with operational data on the actual values of the loss of the useful power of PЕM under various modes of motion of the vessel in real ice conditions. This information can be obtained by the skipper provided that the propulsion system (PS) of the vessel is equipped with an online monitoring system, the initial measured physical values of which are torque, axial force on the propeller shaft and its speed. The equipment of the system should have the minimum possible weight and size characteristics, not to create additional loads on the structural elements of the PЕM and power supply system. The creation of such a system was made possible by the development of in the last decade of radioelectronic chipcomponents based on integrated circuits on crystals, as well as new research results in the field of magnetoelectronic. The purpose of the work is to develop a set of new technical solutions and create on their basis an experimental system for online monitoring of the efficiency of the use of PЕM power in the operation of ships in ice conditions, testing of the prototype system in real conditions of operation of the ship in ice and development of recommendations for its use. The methods and technologies used: The solution of the problem of creating a complex system of online monitoring is based on the complex use of: methods of strain measurement of surface microdeformations and measurements of parameters of displacement on the basis of the Hall effect, followed by the calculation of the torque, axial force, power on a rotating propeller shaft; technology of wireless power transmission on the principle of magneticresonance induction and highspeed wireless data transmission via a digital twoway radiochannel.

 Abstract
 Statement of the problem: Ensuring a win in the conflict determines the need for preemptive detection of the opposing side actions and their neutralization by means of special methods. A promising approach to their development is the use of systematic research methods that allow us to consider the dynamics of the conflict and its main characteristics in conjunction with the actions of the sides at all stages of their functioning. Purpose of the work is to develop a dynamic model of the conflict «opticalelectronic means  laser complex of functional damage”, that is reflects the main stages of the functioning of the sides, taking into account their conflictive conditionality and allows determining the requirements for the parameters. The novelty of the work consists of the systematic consideration of the conflict model «opticalelectronic means  laser complex of functional damage» at various stages of the functioning of the sides. That allowed determining analytical expressions for estimate of successful protection probability of the opticalelectronic means at given times, depending on the values of the technical parameters of the sides. Result: Based on the conflict representation, the «opticalelectronic means  laser complex of functional damage» in the form of a semiMarkov random process with a discrete set of states, a system of integral equations is composed and analyzed, that is allows determining the probability of winning (losing) each of the conflicting sides at different stages of their functioning at specified times taking into account of the total time resource of the systems. Practical relevance: Presented solution is implemented in a software program that allows calculating the probabilistic characteristics of reconnaissance assets depending on the parameters of the conflicting systems, consequently, to justify the parameters of the protective devices of opticalelectronic systems.

 Abstract
 Statement of the problem. The problem of signal processing in telecommunication systems of voice transmission is caused by the lack of reliable a priori information about the characteristics of the observed signals. Therefore, the paper considers methods for estimating signal models in telecommunications systems for audio exchange. Object of research are methods for estimating the statistical characteristics of analog signals, such as the onedimensional probability density of signals and interference in telecommunications, methods for determining the parameters of the observed signals, which are the additive sum of the estimated signal and acoustic interference.

Suppression of acoustic noise is based on adaptive filtering and adaptive compensation methods. The scientific novelty of the work consists in estimating and approximating onedimensional distribution functions and correlation functions from limited data sets and, on this basis, forming the basis of a priori information and allocating the intervals of stationarity of the observed signals. Based on the segmentation of nonstationary signals, their smoothing and local approximation are carried out. Results.

Detection Model of a Ballistic Space Object with a MultiSpectral OpticalElectronic Complex
 Abstract
 Problem statement. Optoelectronic complexes for detecting space objects occupy an important place among informationmeasuring systems. The complexes operate in several spectral ranges simultaneously. The analysis of multispectral detection complexes showed that the issue of dependence of the characteristics of the complexes on quantum kind of radiation has not examined. The aim of the paper is to form indicators of detection quality of space objects in different ranges, taking into account type of space objects coating. This aim is achieved by mathematical modeling in Mathcad, taking into account the quantum kind of optical radiation. Used method. The solution of the problem of detection and recognition of signals from objects on the background of natural and organized interference is based on dependence of probability of correct detection on distance at a fixed value of probability of false alarm and dependence of maximum range of optoelectronic complex on probability of correct detection. The fixed value of the false alarm probability, the quantum kind of the radiation and the different optical radiation ranges are additionally taken into account when solving the problem. Novelty. Elements of novelty of the solution is used of photoemission theory, which allows to connection the statistical properties of the optical energy flow with process of emergence of photoelectrons. Changes in intensity of optical signal, which is reflected from the object make to change the distribution of photoelectrons, which differs from the Poisson distribution. The signal detection operation is performed as calculation of the probability coefficient at the output of an energy detector. Result. The use of the solution showed that the probability of detecting a space object covered by a composition of materials is higher than the probability of detecting an object covered by a homogeneous material. This is because objects that are coated with a composition of materials have a higher reflectance than objects that are coated with a homogeneous material. The probability of correct detection increases if the range of irradiation that is received is shifted to the infrared range. Practical significance. The presented solution is proposed to be used in multispectral optoelectronic complex of space objects detection.

Stability Method of Telecommunication Network with Using Topological Redundancy
 Abstract
 The relevance of problem. Routing protocols that are used in networks work perfectly with static network topology. However, if the topology changes rapidly, routing protocols do not provide fast network recovery. Therefore, the development of new methods to improve routing protocols and improve the stability of the networks is relevant topic research. The aim of the paper is to develop a method of ensuring the stability of networks. The method is based on the use of network topological redundancy. Novelty. More efficient management of network topological resource is implemented in the method. In particular, formation of additional backup paths and maneuvering with routes for transmission of traffic are used in this method. If the network topology changes, the routing protocols switch the traffic routes to the backup paths and transmission the traffic is not interrupted. The practical significance of the paper is that the proposed method can be used to improve the routing protocols of networks (OSPF, EIGRP, PNNI, etc.) and to improve the stability of the networks.

For this reason, the airborne warning and control system (AWACS) is used as an air command post to control the aircrafts. However, factors such as high intensity of flights, a large number of aircraft controlled in parallel from AWACS, have identified the need for a more rational use of resources of the integral radio network of AWACS. As one of the most important task in this case have been the organization of routing as commands and information messages in the integrated radio network. The model of the integrated radio network of aircrafts control from AWACS with a hierarchical principle of routing is considered in the paper. The model allows evaluating the effectiveness of different ways of organizing communication in the integrated radio network for informed choice the most rational way. This rational way of routing is to be introduced in software of communications system of AWACS.

Algorithm of centralized multipath routing with load balancing for nongeostationary telecommunication satellite system with intersatellite links
 Abstract
 Purpose. The capacity of nongeostationary telecommunication satellite system (NGTSS) with intersatellite links is precious and scarce (compared to terrestrial telecommunication systems) resource. Subscribers terminals are unevenly distributed on the Earth and data flows from terminals are oscillating drastically during the day. Hence, the uneven distribution of data flows and interstatellite links overloading forms, which leads to the loss of data packets. To prevent packet loss, it is necessary to create the effective routing algorithm with load balancing. The goal of paper is to create the algorithm of centralized multipath routing with load balancing for NGTSS with intersatellite links. Methods. The methods of graph theory and optimisation theory are used to create the algorithm of multipath routing with load balancing. Novelty. The new algorithm of route sets with a minimum number of common links search and the new algorithm of packet loss probability estimation due to link exit buffer overload comprise the novelty of proposed algorithm. Results. The research has shown that proposed algorithm of centralized multipath routing with load balancing provides the low probability of packet loss due to NGTSS intersatellite link exit buffer overload, high throughput of NGTSS, low queuing delay of exit buffers of NGTSS links. Practical relevance. The proposed algorithm of centralized multipath routing with load balancing is acceptable to use for effective control of data transmission in NGTSS under development and, as a consequence, for the increase of throughput of NGTSS and for the lowering the packet loss probability of NGTSS.

Distributed Computing Environment for an Analysis of the Vulnerability of Critical Infrastructures in Energy Sector
 Abstract
 Relevance. Protecting energy infrastructures and supporting their survivability are topical problems on a national and international scale. Generally, a study of the vulnerability of critical technical infrastructures in the energy sector is based on combinatorial analysis of a large number (about tens and hundreds of millions) of failure scenarios in infrastructure elements. Carrying out such an analysis requires the use of highperformance computing systems. The aim of this paper is to develop a new approach to studying the current threats to energy security based on an analysis of the vulnerability of critical infrastructures in the energy sector using the paradigm of distributed computing. Methods. To develop a subjectoriented environment, we apply the models, methods, and tools for Grid and cloud computing. We also use methods and tools for creating distributed applied software packages. Novelty. Unlike wellknown specialized environments that support subjectoriented research, the developed environment provides the creation of distributed applied software packages, the integration of models for Grid and cloud computing, and the choice of the optimal resource configuration for performing experiments of various scales. Results. We developed the functioning principles and architecture of the subjectoriented heterogeneous distributed computing environment for investigating the current threats to energy security based on the analysis of the vulnerability of critical infrastructures in the energy sector. The created subjectoriented environment was applied to solve a largescale problem of identifying critical objects in the Russian gas transmission network from the standpoint of energy security and finding ways to reduce the negative consequences in the emergency at these objects. We formed proposals on the firstpriority technological development of critical sections of the network on the basis of the results of solving the problem. Practical relevance. Realization of the formed proposals will allow providing the temporary increase of the critical arcs capacity about 10%.
