Published: June 2019

Abstract
In this paper, the solutions for problems related to increase in manufacturability of pipelines at a design stage were stated. The authors considered conditions and possibilities for compensating deviations of the pipeline route and adjacent structures during pipe installation. The task was set to produce a fitting pipe according to the design information without specifying dimensions and configuration in place on the ship. The fitting pipe was manufactured according to the design information with the assignment of technical allowances at the end sections in certain directions, if necessary. Moreover, the authors presented a method for compensating deviations in the routes of ship pipelines using rotations of pipe parallel section pairs, and developed the procedure for compensation and installation of pipelines from prefabricated pipes manufactured according to design information without specifying dimensions on the ship. Mathematical and graphic modeling of deviation compensation in pipelines during their installation was performed.

Authors: Ngo G V , Tham B C 
Published: June 2019

Abstract
In this paper, we studied the current state of the design, manufacture and installation of marine pipelines, and considered the problem of manufacturability improvement marine systems pipelines at the stage of designing, providing the possibility of manufacturing the pipes without taking actual sizes and its solution within the framework of the research of the interrelation of configuration and compensation possibilities of the pipeline routes. The problem of compensatory possibilities of straight pipes on pipeline routes with a camber or with two and more cambers was examined. It was established that at simultaneous rotation of two different pipes with parallel ends, the end point moves along the surface (if the axes of these pipes are not parallel); at rotation of three or more pipes with three non-coplanar axes (i.e. not lying in the same plane) the compensation range is a three-dimensional body. The method of calculating the possible compensation area was improved in order to reduce the amount of computation. As part of the hypothesis about the relationship of the configuration and compensatory capabilities of the design pipeline routing, the idea of using straight pipes to move the pipeline route in order to compensate for errors in the manufacture of pipes and the installation of rigidly fixed connections of equipment, saturation products, etc., was presented, which ensured the collection of the route pipes.

Published: June 2019

Abstract
In planetary cycloid gears the motion is transmitted simultaneously to many pin-rollers and teeth of cycloid disk. The use of schemes with many parallel contacts requires measures to ensure the assembly of the gears due to the introduction of malleable elements or guaranteed gaps in the contacts into the design. In the paper the analytical decision of the problem of the gap impact in gearing of planetary cycloid gear to the load distribution on the teeth of the cycloid disk, the maximum forces acting on them and friction losses in the contact of the teeth of the cycloid disk and pin-rollers is reviewed. The calculated dependences for the coefficients of the load increase due to the gaps and the effect of the gaps in the gearing on the losses on the sliding friction are obtained. The results of calculation of the load increase coefficient in gearing and the clearance influence coefficient on friction losses in gearing are presented. This decision allows to take into account the possible increase in the load of the contacts and the change of the coefficient of loss in gearing at the design stage.

Abstract
The article analyzed and identified the main sources of interference, disrupting the work and reliability indicators of the system, which can lead to malfunction of system of microprocessor relay protection and automation for electric stations and substations, as well as elements and actuators of open distribution devices. According to official data, modern microprocessor-based relay automation systems operate with a reliability coefficient that is not lower than 0.998. Further increase in reliability requires the development of technical measures, namely, requires the use of power and signal cables that must meet the requirements for specific parameters of inductance, capacitance and active resistance, and also requires the use of special placement of cross sections of conductors inside the cable. Secondly, it is shown that to increase the reliability of information transmission it is necessary to switch to serial communication channels, but the amount of information per channel should be strictly limited. The estimation of economic indicators of the system and its dependence on the reliability of the system is given. Thus, with an increase in reliability by 1.5-2 times, it is necessary to increase the cost of design and commissioning of such a system by about 2 times. It is recommended to use in addition to the regulated maintenance procedures a mandatory assessment of the level of interference in the system in order to maintain a stable and reliable operation of the relay automation system. Experimental and calculated data confirmed that the most difficult situation to ensure the reliability of the system is associated with thunderstorms and lightning. This circumstance dictates the necessity of evaluation and measuring the parameters of a common system of earthing. The methods of evaluation and diagnosis of faulty components of the system are proposed.

Secondly, the nonlinearity of the hysteresis dynamic characteristics of the suspension is taken into account, with the help of which the dynamic stiffness of the leaf spring is considered. The dynamic stiffness is depending from the dry friction between spring leafs and the amplitudes of cyclic oscillations with a random external road forcing. Thirdly, the accuracy of the installation scheme of the leaf spring in the vehicle suspension is considered. It takes into account the peculiarities of fixing the leaf spring and their impact on the change in stiffness.

Authors: Dorrer Georgy , Dorrer Alexandra , Yarovoy Sergey 
Published: June 2019

Abstract
Due to global climate change, the probability of damage from natural and man-made disasters has increased. These processes are becoming less predictable in scale and impact. If we consider the heterogeneous natural and anthropogenic processes on the surface of the Earth, we can see that despite their different physical nature they have the following common features. All these processes, due to their characteristic dimensions, are amenable to mapping. In this regard, the use of GIS technologies in their modeling becomes necessary. Remote monitoring methods can be applied to all classes of such dynamic processes. From the point of view of control theory, the listed objects are objects with distributed parameters and distributed control. The possible methods of controlling these processes are similar and often do not depend on the nature of the process. The purpose of this work is to create and implement models of dynamics and control of the above processes as GIS-oriented multi-agent systems based on the use of the formalism of embedded Petri nets. At the same time, as a specific process, on the example of which modeling and control methods are considered in more detail, wildfire is selected.

Published: June 2019

Abstract
In recent years, issues related to the protection of the environment and the preservation of the environment for future generations come to the fore. This issue is most relevant for industrial enterprises whose capacities were commissioned 40-50 years ago, while at the same time there was no qualitative and quantitative renewal of equipment for this period. The paper reviewed the indicators of emissions of pollutants by economic activity, as a result, it was concluded that about 26% of all emissions are generated as a result of the functioning of the fuel and energy complex. At the same time, the costs of environmental protection increase by the level of annual inflation and the volume of costs of environmental protection as a percentage of the gross domestic product of the country tends to fall. In the conditions of instability of the national economy and limited financial resources, the authors of the study proposed a mechanism for the formation of an environmental strategy for the fuel and energy complex of the Russian Federation, which is based on a tripartite interaction of state and regional authorities and energy companies.
