Industrial networks now are trying to implement wireless technologies, following the tendencies in communication networks. This task is complicated because of the nature of the industrial environment. Wireless connections hardly achieve the same stable quality of service (QoS) parameters as traditional cable ones. Interference is one of the reasons for that and effective solutions should be developed for its reducing in order to maximize the throughput of the wireless media. Balanced geometric model, which reduces interferences between end-users and access points, is proposed. It is based on Nash Equilibrium Theory and gives opportunity to control the output power of wireless devices in optimal way. The use of vectors in the model helps to analyse in details, impacts between the neighbour points – their power and direction. At the end, there is a sample for using balanced geometric model in industrial network.

This paper focuses on design and evaluation of control system for ambient assisted living system based on voice and gestures recognition by using Microsoft Kinect. Many modern and innovative applications use voice and gestures as input. These programs span a wide variety of genres, platforms and input technologies, from the touch screen of a smart phone to the full-motion, natural input of devices like the Kinect for Windows Sensor. There are some project’s objectives: analyzing of existing voice and gestures recognition algorithms; development of a Kinect-based voice and gestures recognition system for better human-computer interaction; integration of the command system with other parts of AAL environment.

This paper considers algorithms for concurrency control in Distributed database (DDB) systems. Below are the simulating models of the implementation of two-phase locking (2PL) in DDB. From four types 2PL in DDB (Centralized 2PL, Primary copy 2PL, Distributed 2PL and voting 2PL) is viewed Primary copy 2PL, as this protocol is a "transitional" protocol of Centralized 2PL to the Distributed 2PL. The paper describes specifically the simulations of two-version 2PL and 2PL with integrated timestamp ordering mechanism. In concurrency control method 2PL may take place deadlocks of the transactions. Therefore, in the modelling algorithms described here are integrated algorithms for deadlock avoiding: two-version architecture of database and timestamp ordering strategy “wait-die”. There are also presented, the results of the simulations of these two variants of the 2PL method at different scales of the networks for the transmission of data and at different intensities of inflow transactions. Modelling algorithms are developed by means of the system for simulation modelling GPSS World Personal Version.

The developed model allows for quantitative assess the maturity level of processes of software projects and to identify priority areas for the development of software project processes. The model was tested on 10 companies. Spent in the company survey allowed us to estimate the level of maturity, to collect data on deviations in time and the cost of the project and build the equation of dependence of deviation from the measured level of maturity. This equation can be used by companies to predict the variation of key indicators of the project when changing the maturity of software processes.

The structure and characteristics of human emotional maturity have been studied. It was worked out a program (based on software “Sheriff 7” of polygraph “Barrier-14”) for testing a peculiar personal characteristic of juveniles - deceitfulness. Earlier developed diagnostic methods were applied to measure the emotional maturity of a person. The correlation between the emotional maturity of juveniles and their deceitfulness was established using a polygraph method. It was revealed that the low level of emotional maturity corresponds to the weak abilities of juveniles to lie. A research of ethical and social values of contemporary juveniles was undertaken to determine the areas in which the deceitfulness is most pronounced.

The urgency of developing information and training system based on multicriteria decision-making model is due to both scientific purposes better understanding of the information processes of learning and practical objectives to create more effective information and training systems, the implementation of which contributes to the quality of distance learning. The transition to this technology involves the use of new teaching methods, approaches, principles of organization of the learning process, including on the basis of information and training systems. Therefore, in this paper concerns the problem-oriented learning management based on multicriteria decision-making model that takes into account the level of doubt the user. The proposed method of measuring the level of doubt the user gives a clearer and more "transparent situational picture" for a more objective decision-making. Also, the method makes it possible to reduce the probability of guessing the correct answer, which increases the objectivity of knowledge in diagnostic systems for process control training on remote technology.

The carried-out analysis of catastrophic mudflow in Medeo tract in 1973 showed that the abnormal operation of the dam spillways was associated with several deficiencies in the mud dam’s construction and unexplored process of deposition of the solid phase of the carrier medium mudflow mass trapped in the mudflow storage reservoir. Subsequent completion and modernization of spillways was made taking into account the effects of the mudflow in 1973 and now they do not structurally allow catastrophic mud flow cram the mudflow storage reservoir. The article presents a method of controlled dumping the treated fraction from the solid one of of carrying water phase of the forecast catastrophic mudflow through modernized spillways of Medeo mud dam. The proposed approach allows protection from flooding the social-culture objects of Medeo tract through optimal work of spillway that controlled using computer model of automated dam’s control and safety system.

The biomimetic robotic fish shows great potential of surveying of resource, military reconnaissance, the monitoring of water environment and so on, so the biomimetic robotic fish is a hot issue with great challenges. Although the current CPG controller of generating sine signals can also control the movement of robotic fish, but this kind of controller needs many parameters.According to the fish body wave function proposed by Lighthill we design a new CPG controller. This controller can efficiently reduce the parameters of controlling robotic fish movement and realize the simulation of the fish body wave curve. In order to test the feasibility and effectiveness of the CPG controller. We realized the virtual reality simulation and test it in a three joints of robotic fish.
