It is customary for the preparation of technical documentation to use CAD (computer aided design) systems. Depending on the design and functionality they are divided into low, medium and high class. In certain cases, there are developed alternative software applications or such added to other basic systems with broad opportunities for development. At the present time open source programs are more widely used. This reinforces the interest of designers, engineers and architects to find possible application of such programs in the workflow. Contemporary and very good solution gives Blender free software with specialized application "MeasureIt".

In this paper, we study on chaos, one of the most important phenomenons based on complex nonlinear dynamics. We will focus on T-system chaos and in continue, using three synchronization methods, Brain Emotional Learning Based Intelligent Controller (BELBIC), Generalized Backstepping Method (GBM) and adaptive method, the chaotic system will be synchronized. To prove usability of the controllers, the results will be compared with the results obtained by Active Control and Backstepping Controllers. According to the results, proposed controllers synchronize chaotic systems with higher speed, lower setting time, lower overshoot and smaller control signal versus active control and backstepping controllers.
Investigated the features of the structure of the thin-film coatings based on polymeric and oligomeric matrix formed by dipping, spraying or rubbing. It was found a significant effect of energy substrate parameters and components of the coating on the mechanisms of interfacial interactions that determine the parameters of strength, tribological and protective coatings. The active layer morphology of the surface of the substrate formed by mechanical, laser or chemical influence, characterized by the presence of low-dimensional components of different habitus, which affect the energy and mechanical component adhesive strength. By managing service parameters of composite material components on the basis of polymeric and oligomeric matrix manages to change the mechanisms of formation of coatings on metal substrates of carbon steels and non-ferrous metals. Coatings based on the thermal ablation of PTFE products are effective in the process of running heavy-duty friction units and their operation at reversing the motion. Installed effect Nanophase formation regions in the volume of the coating, which help to increase their durability in friction without external supply of lubricant.
This paper, concentrates on a three-dimensional (3D) computational fluid-dynamics (CFD) model for coal combustion and electrode radiation inside an electric-arc furnace (EAF). Simulation of the complete EAF model includes combustion reactions of coal particles and radiation from electrodes. Particle surface and gas phase reactions were used to predict injected coal particle combustion. The CFD model provided detail information for the coal particles combustion and radiation interactions phoneme inside the electric-arc furnace.
Results showed that CFD simulation could efficiently be used to develop and investigate EAF in design phase.

OPERATIONS SYSTEM AGILITY – THE UNDERLYING FACTOR FOR MASS CUSTOMIZATION AND THE MOST IMPORTANT FEATURE OF NEW INDUSTRIAL REVOLUTIONpg(s) 3-6
Modern products become more and more complex and along with this, the requirements for reducing time-to-market and costs are increasing continually. The demand for customized products is growing at the same rate, as well as the search for more effective and efficient utilization of resources and energy, which is already a distinguish feature of industrial development nowadays. In turn, increased agility and velocity of production processes significantly increase the requirements for modern production systems. In order for industrial companies to survive and keep their competitiveness in such a dynamic environment, they must not only increase their productivity, but to improve their operations strategy in terms of agility as well, offering their goods and services. Latter puts new challenges to modern companies.
Due to increasingly competitive is required the companies to provide personalized products and services. This contributes not only to ensure custumer satisfactition, but also to require application of modern technical solutions like digitized solutions, specialized software, automation of production and services. All these changes are the foundation and the specificities of the fourth industrial revolution ("Industry 4.0)." This article performs the key features and principles of Industry 4.0, just like and the role and the requirements to the human factor. In this connection there are different scenarios applicable to companies in the light of the fourth technological revolution.
The rapid development of innovative industry started to impose so-called service-oriented platform of product development, which means intelligent monitoring, or that the product will be monitored throughout its life cycle – from concept to recycling it. These intelligent products (Smart Products) have informational knowledge of their production processes, logistics and future applications. They actively support the production processes (when they will be produced, with what parameters, what materials should be produced, where it should be delivered, when, what modifications, etc.). In this environment and these conditions the logistical component has a qualitatively new dimension adapted to meet these new requirements imposed by the innovative development – namely, to be in constant optimal contact with the production cyber system.
Robot assembling is flexible and it enables a stable and high-quality assembly. It enables a constant improvement and an easy multiplication. This report represents an idea for adding functionalities in a robot complex for assembling flame detectors in the firm “UniPOS” and it analyses the benefits of this. The main aims for a development of the existing robot complex for assembling are: decreasing the production prime cost; reducing the manual labor that is connected to loading components; increasing the use of the robot complex; reducing the cycle time and increasing the productivity of the robot complex; increasing the quality of the manufactured products. The additional functionalities are accomplished in parallel with the main ones in assembling and they are at the expense of running all robots in the complex and their use only for assembling (not for loading the components).

TOWARDS A NEW INDUSTRIAL ORGANIZATION: A GLANCE AT THE POLITICAL ECONOMY OF CLAUDE HENRI DE ROUVROY, COMTE DE SAINTSIMONpg(s) 39-41
Often referred to as Henri de Saint-Simon, the Comte (1760-1825) offered a new and contemporary organization of ideas and practices. He said it was necessary to put an end to the critical phase of feudalism, the 18th and 19th century revolutions, the wars, the intolerance and egotism of the old regime. This transformation, he said, could be achieved by industrialism. Saint-Simon established the doctrine of industrial progress. He was the first to create the doctrine of industrial progress, the first theoretician of industrial society and technocratic political reform.

tool and cutter grinding machine, with computer numerical control (CNC).
INCREASING THE RESISTANCE OF PRECISION INSTRUMENT-MAKING ELEMENTS FROM OPTICAL GLASS TO EXTERNAL THERMO-INFLUENCES BY PRELIMINARY ELECTRON-BEAM PROCESSING OF SURFACESpg(s) 9-12
The results of experimental studies to improve the properties of the surface layers of the elements of optical glass (K8, K108, K208, BK10, TF110) after their processing by mobile electron beam with density of heat exposure Fn = 7·106…8·108 W/m2 and displacement speed V = 5·10-3…5·10-2 m/s (a reduction of residual microroughness height at the surface from 4 … 6 nm (unprocessed elements) to 0.5 … 1 nm (processed elements), the occurrence of melted layers of thickness up to 250 … 300 microns with a modified
structure, which is close to the quartz glass) are presented. It was found that the improvement of these properties increases the resistance of elements to external-heat: an increase in 1.3 … 1.7 times of the critical value of external heat fluxes and the time of their exposure, the excess of which leads to the destruction of elements and damage to the test instrument turndown external pressure 105…107 Pa; increasing the maximum permissible values of thermal stress in the elements from 20 … 40 MPa to 90…100 MPa heating temperatures 300 … 1200 K; an increase of the probability of failure-free operation in the 2 … 2.5 times by increasing the speed of the external heating from 100 K / s to 400 K / s.
