In modern industry, welding plays an important role for jointing materials and arc welding has been the dominant process for many years. In general, in order to produce a high-quality weld, the system should have two main functionalities. First, it should have the capacity of directing the welding torch based on the detection of the joint location and geometry, namely “seam tracking”. Second, the system should be able to adjust the welding parameters, namely “adaptive control of the welding condition". Both functionalities heavily rely on the sensor systems. The analysis of welding technological processes, adaptive control and intelligent  systems proved the  opportunity of utilization artificial neural networks in the procedure of  weld seam tracking and weld head movement control. Welding process engineering and adaptive correction with artificial neural networks  are considered in the paper both with the computer vision system based on video monitoring and laser profilоmetry.  The paper is focused on the development of a proper sensor system to facilitate the arc welding automation and neural network-based control to provide precise seam tracking and high-quality joints.

The main methods of Platycladus orientalis seed propagation are studied. For Platycladus orientalis industrial cultivation the following technologies of reproduction are recommended: For off-sort samples – seed propagation after stratification (25-30 days); For sorts and decorative forms:
1.Vegetative propagation using IAA.
2. Micropropagation of Platycladus orientalis in vitro by means of adventitious shoots induction on the MS medium adding 0,2 – 0,5 mg/l BAP. There are derived well rooted microshoots on the medium with IAA in concentration 5 mg/l.

Keywords: green building, Platycladus orientalis, technologies of reproduction, clonal micropropagation.

A comparison of wheeled and tracked vehicles propulsion forest. It is shown that the bulk of overseas logging operations, the construction of infrastructure facilities, the primary transport of forest produce machines with paddle wheels. It is proved that under natural conditions of production are tracked significant potential movers. Given the requirements of prospective car on the engine power, weight, ground pressure, speed and carrying capacity.

The article discusses the possible causes of pollution of Taganrog Bay of the Azov Sea with oil products for the period 2008-2013. The key factors of pollution were highlighted. Effects of navigation for cotion was evaluated by navigation intensity. Effect of wastewater was evaluated by the number of oil products which fall from municipal drains and wastewater from industrial plants. The data processing of the federal statistical reporting on the influence of the main contamination factors was carried out.

Keywords: oil products, water pollution, average annual concentrations

The article describes the main theoretical approaches and issues of transparency of customs regulation of foreign economic activity as a basis for the development of integration processes in the framework of the Customs Union and the Common Economic Space created by Russia , Belarus and Kazakhstan . Conclusion are made on the need to enhance the interaction of state bodies with the business community in assessing the effectiveness of the customs authorities, improving the system of providing public services by the customs authorities, creating a system of regulatory impact assessment of draft legal acts on foreign activity.
