Description
The role of transport in agricultural production is significant. It is the connecting link in the technological chain of the agro-industrial complex (of the APC). On-farm transport in the APC together with cars and tractor transport are widely used. The rationality of the use of wheeled tractors for farm transport substantiates the possibility of their movement on asphalt and on dirt roads. The specific gravity of the tractor transport in the domestic agriculture is 22-27% of the total volume of transport and 50-60% of the volume of farm traffic. A high level of use of tractor transport has been observed in the countries of Western Europe and the USA. In the farms of leading countries of Western Europe (Germany, Italy, France, etc.) about 70- 90% on-farm transport of agricultural goods is done by tractor transport. Tractor transport in a live environment is running on roads with varying terrain, a wavy profile cover, on soils with different hardness and humidity. When driving vehicles at high speeds, the trailer is wobbling from side to side, constantly accompanying tractor transport during its operation. As a result, it is bad for propulsion, transmission, and it deteriorates the dynamic performance properties of equipment, working conditions of the operator. To reduce the amplitude of oscillations of the trailer, the operator is forced to work strenuously with the steering wheel or to slow down the speed, which in turn affects operator fatigue, as well as the performance and maneuverability of the vehicle. Thus, advanced technologies in electronics, sensor technology and software will determine the nature of agro-technical innovations and will lead to increased automation of business processes in crop production with the aim to organize the work more effectively, efficiently, accurately, environmentally friendly and economically feasible. When working with intelligent technologies, understanding the development of high-tech, precision engineering requires a revision to the personnel policy and education in agriculture, which should be based on the relevant organization of farms and their proper new type engineering solutions

FEATURES OF THE DEVELOPMENT OF AN INFORMATION LEARNING SYSTEM
DescriptionNowadays, a necessary condition for progress in the field of information technology is wide adoption of standards and technologies of information systems used for hardware and software products. Building software of computing and information systems, based on the ideology of open systems, allows to successfully solve the problems of portability on platforms of various manufacturers, the problem of interchangeability of components and, most importantly, ensures the integration of devices and users in a variety of computing and telecommunication networks. It should be emphasized the fact that to date the successful implementation of any significant projects in the field of information and computer technology, management of information and telecommunications is not possible without coordination of development with existing standards in the field of information systems and, in some cases, the development of new standards. In the conditions of transition to integrated computing and telecommunications systems, the principles of information systems form the basis of technology integration, the establishment of sectoral, regional and national information infrastructures and their interactions on a global scale. So, we can conclude that the technology of information systems today is the working environment in which the priority is the development of information and telecommunication technologies, telecommunication and computer engineering

FEATURES OF THE CALCULATION OF DEAD-END CHANNELS FOR THE CASE OF AUTOMATED IRRIGATION SYSTEM
DescriptionIn this article we consider the method of hydraulic calculation of dead-end channels with the numerical solutions of differential equations of motion of water. Dead-end channels are of interest for carrying out simulation studies, because they may be used for the simulation of water accounting and water distribution in the domestic inter-farm network. In order to improve management of water supply to consumers in the water distribution sites, in many irrigation systems there is an additional capacity in the form of a regulation pool. The applied method of active control of light distribution is expected to use the existing capacity of irrigation canals with automatic regulators to block the plants. When there is a complete disconnection of water consumers, the volumes in pools of water irrigation channel are redistributed to provide the command area in the water distribution nodes at any given time. This result can be achieved by automatic control of the level changes in individual pools of the channel in order to redistribute the volumes to backup pools of individual. Search and selection of the necessary rule of automatic controls can achieve the following objectives: to implement effective processes and management of water supply regulation in the specified node; maximize the use of volume tail water channels, preventing the threat of overflow channels; minimize the loss of irrigation water discharge

FEATURES OF CALCULATION OF THE NONCONTACT ELECTRIC POWER GENERATORS
DescriptionThe article shows that to improve the performance of autonomous systems we need new methods and principles of their design, associated with both the use of renewable sources and the application of new technical solutions of electromechanical generators and static stabilizers and inverters electric power settings. We have disclosed modern requirements for generators of electric power, as well as features of calculating the parameters of contactless electrical power generators: asynchronous generators capacitive excitation and asynchronous generators with permanent magnets. The article presents some analytical expressions for calculating the electrical losses and the efficiency of the generators, specific weight and power. It is shown, that expedient to designing contactless electrical power generators to carry out as part of the autonomous electricity supply systems, as it is sometimes advantageous to understate the main criteria of efficiency of generators, in order to improve, for example, weight and overall dimensions of static converters. The conclusion is made that in order to improve the efficiency of designing contactless electrical power generators in the early stages of designing it is necessary to carry out a preliminary assessment of the main criteria of efficiency of contactless electrical machines. We have also discussed analytical expressions, which might be used for preliminary evaluation of application features for various types of contactless generators in the stand-alone electricity supply systems taking into account the conditions of use

ISSUES IN IMPLEMENTING MARKER BASED TRACKING ON MASS MOBILE DEVICES
DescriptionTracking is a vast field of research associated with navigation, robotics, and virtual environments (virtual reality). Tracking for augmented reality requires higher level of precision, increased range of action, as well as work with a wider variety of input data. It is important that augmented reality technology requires tracking in real time, which also complicates the task. Correct visualization of objects in three-dimensional space requires six degrees of freedom tracking: three position values (x, y, z) and three angles (rotation around the respective axes) to determine the orientation. To solve this problem, different approaches and sensor types are being used. In this article, we present a brief history of the development of tracking technology and analyze the current approaches to implement the process of tracking on mass mobile devices such as smartphones and tablet computers. We also describe some issues in implementing optical marker based tracking for visualization of large scale models
