    The paper highlights some approaches to fundamental problems of intelligent control of autonomous underwater vehicles (AUV) groups: logic-based approach to task management for inspection and protection of the water area, hybrid evolutionary models and algorithms for dynamic mission planning, and methods for rigorous analysis of discrete-continuous models of AUVs formations with discrete-event approach to AUV’s operational modes switching. Hierarchical three-level architecture of control system is supposed and various models of AUV group functioning at the different control levels are considered.

    There are many variants of solar collectors on the market with their advantages and disadvantages. The innovative solution of solar thermal collector has been done to increase efficiency and improve design. The new constructive solution presents good combination of an attractive design and appropriate constructive materials with special geometric shapes. Hydraulic and thermotechnical tests of this collector showed high hydraulic and structural stability. The main disadvantage is selective electrochemical coat and further development of the solar collector will be in order to improve observed disadvantages.

    Solar collectors are one of the most promising renewable technologies for energizing future systems. Solar collectors are used for a variety of heating systems such as domestic hot water systems and industrial application. Increasing the collector efficiency is an important factor in terms of unit cost. In this study is to increase efficiencies of flat plate solar collectors. For this purpose, various apparatus was place into collector tubes which increase the heat transfer between plate and fluid, thus it developed a new collector. In addition, a new collector hot water tank was designed. The changes in warehouse and collector were compared with the classical systems and the change in the usage water was calculated.

    The report examines the use of steganography as a method of hiding text, images or sound recordings in file-carrier for mobile devices, which may give the opportunity to keep the correspondence without awaking any suspicion. The information file is hidden in the filecarrier by the method Least significant bit (LSB) through various algorithms of coding. The experimental part compares mobile applications, which are using Steganography methods and compares their advantages. The experimental results show that the Ultra Mobile Steganography is realizing with fast pace, the applications have common static characteristics of the cypher image and are easy to use.

    The article analyzes the distributed technological complexes of the Republic of Kazakhstan as objects of control and monitoring. Examples of distributed technological complexes are the oil transportation system, the mega-cities heat supply system, highvoltage power transmission system. Two distributed technological complexes were analyzed. The aim of creation and application of control and monitoring system for each complex is substantiated. A structure has been developed for constructing a control and monitoring system for the heat supply system for megacities and a high-voltage power transmission system. The generalized functional diagram of the upper level of the monitoring and monitoring system was developed.

    Customers demand a guaranteed availability of machine components in capital goods industry. However, manufacturers are not willing to guarantee the demanded availability due to increasing costs based on high risks and uncertainties resulting from missing operational data, insufficient transparency of the machine condition as well as missing information of the customer behavior. In the following paper, a strategy to enable the development of availability-oriented Product-Service Systems (PSS) will be presented. Therefore, a use case focusing on the agricultural industry is regarded. Based on the use case, service-relevant parts will be identified and failure mechanisms of these parts will be determined. The subsequent development of condition monitoring strategies depend on the determined failure mechanisms. In a last step, the strategies will be assessed and the strategy with the highest added value will be chosen for an exemplary implementation, for which an electric motor and a conveyor belt of a potato harvester will be used.

    Until now, the majority of ergatic control systems in various technological areas are based on a functioning independent of the maintenance process. This approach reduces the efficiency of maintenance and the safety of the system. The report proposes an alternative model of the system’s behavior, based on interactive interaction with both operational and technical staff.
