OPTIMIZATION OF THE FILLABILITY OF CLAW-SHEARING DEVICE
DescriptionDuring the study, the authors have solved the problem of determining the minimum number of operations by optimizing fillability of a claw-shearing device with trees. Sufficient optimality conditions have been obtained. The numerical method for solving the optimization problem was developed. We have also performed a numerical experiment

PYROLYSIS OF FOREST RESIDUES IN THE CHARCOAL FURNACE
DescriptionThe article presents the modernization option of the forest residue furnace that allows speeding up the drying process by boosting it. The dependencies, reflecting the influence of the temperature of the drying process on the heat losses of the furnace and the effect of the load and the moisture content of the feedstock to the fuel consumption for the entire drying process, are presented in the article

EXPLOITATION OF LIFE SUPPORT SYSTEMS IN POPULATED PLACES
DescriptionThis article describes aspects of control, regulation, functioning and degree of influence on the condition of life-support systems, on the safety of life support, on the safety vital functions of society. The impact of life-support systems on the ecological status of builtup areas. The article refers to an increase in emissions and the dangers of СО2 и SО2, about methods to reduce them. It presents the dangers of hydrogen compounds, nitrogen, chlorine, freon. We have also presented measures to protect the environment in urban areas

ENGINEERING SUPPORT PARADIGM OF SUBJECT-ORIENTED CONTROL TECHNOLOGIES
DescriptionThe article presents the basic antilogy, which is attributed to forming an engineering support paradigm of new technologies related to the subject-oriented control in the noosphere, between the demand for an automatical creative thinking of a control subject and the vigilance of society to possible adverse effects of its subjective activities. It is stated that the noosphere, which showed miracles of automation and cybernation, covers all types of human activities, excluding above original positions, which they barely touched. Uppermost it is related to the central economics problem (economy management) – the choice. The problem how to build an engineering support paradigm of subject-oriented control technologies is analyzed; it is based on the known subject-oriented control concept supplemented by concept-based models of the intuition mechanism, which assume its modeling based on formal systems with the purpose to automate control subjects mental activity. From the standpoint of Schopenhauer’s cognitive theory, a research method is developed to investigate evolution and becoming of a particular human category – engineers, which are responsible for the steady development of noosphere of Vernadsky. As a basis, a dynamic phylogenesis model of engineer’s figure was taken, including ready and effective vectors with parameters (education, intellect, skills) and (prevision, choice, emergence), respectively. The results of ontogenesis modeling are given – regularities in future engineers’ preparation as a platform for quantization and convolution of its levels based on modern mathematical methods, including those for support engineers of subjectoriented control technologies

AN ELECTRIC MODEL OF A CITY TRANSPORT NETWORK
DescriptionThe main characteristics of a transport network are the intensity of the traffic flow, speed and density of its traffic. Comfortable driver's traffic density is determined by the rule of the traffic police, which is "clearance between cars on the road should be a tenth of the speed of movement." We have built a reference curve of the density function of the flow of vehicles on its speed, which is basic when simulating a traffic flow. The article describes a model of electrical city transport networks, allowing calculating traffic flows, their speed, the density and the number of traffic lanes by means of laws of electrical engineering. We have also compared electrical concepts (current, resistance, electro-motive force, etc.) and transportation (of intensity-flow lane road, transport driving force, etc.). For the transport network there are methods of calculation of electrical circuits - a method of Kirchhoff's laws, loop currents, etc. We have confirmed the correctness of electric models and the possibility of its use for the calculation of transport networks; as well as we have presented an example of the calculation

ANALYSIS OF THE PROBLEM AREAS IN THE KRASNODAR TRANSPORT NETWORK AND ACTIVITIES TO DISCHARGE THEM
DescriptionThe main causes of congestion in the city are single-level intersections regulated by traffic-lights and an insufficient number of lanes. The article provides an analysis of two problematic intersections and suggestions for their discharge. For trilateral junction of Yaltinskaya - Uralskaya with an electric model it was determined that the number of lanes needed for different areas increased to 4 - 8. However, the causes of the conflict - the intersection of two competing streams – the turn from the bridge to Yaltinskaya street to Uralskaya and oncoming traffic from Yaltinskaya to Severnaya. Traffic light regulation does not solve the problem and helps creating congestion. It is proposed to separate traffic flows on different levels with the help of the overpass on Yaltinskaya, and the stream from Yaltinskaya to Severnaya goes on the overpass, and turning stream to Uralskaya - under the overpass. Traffic flows at the intersection on Severnaya and Turgeneva with traffic light regulation device can be diluted with a circular or a turbo intersection

PRINCIPLES OF ORGANIZATION AND OPERATION OF COLLECTIVE TAXI
DescriptionThe volume of transportation of passengers by taxi is 6-9% of the total traffic of all kinds of public transport depends on the size of the settlement. The main purpose and the advantage of a cab is providing services for the transportation of passengers on the route, appointed by the customer, around the clock work and comfortable travel. To unload the transport system of the city, especially during peak hours, it is proposed to introduce a new type of operational-servicing passengers - a collective taxi. It is designed to transport multiple passengers traveling in the same direction, but with different destinations landing, while the fare is much lower than in a normal taxi. In organizational sense, collective taxis can be a unitary taxi company with the official standard structure and the quantity of the workers or a division of the taxi park of the city

Description
The article describes the process of creation of an adaptive control system with a reference model to stabilize the temperature of drying agent. It is shown that the closed systems work with the operated models is quite satisfactory and therefore can be implemented in production. The increase of the gain of the controller allows reducing the duration of the transition process by one third, almost without changing the dynamic cast

OPTIMIZATION OF DIGITAL CONTROL SYSTEM OF THE PROCESS OF GRAIN DRYING
DescriptionThe article is a study of digital continuous system and optimization of digital control systems. It is shown that the standard in the synthesis of digital systems should provide a continuous system, so first we need to create the desired continuous system and then we could try to get the digital system closer to it
