A mobile robot has been developed to monitor the state of the atmosphere and phyto-condition in protected ground facilities to form control strategies that maximize production profits. The free and open ROS (Robot Operating System) software shell was used as a basis for building a mobile robot information system. The paper considers a non-contact method of assessing the condition of plants (formation of the number of flowers in the inflorescence, the number of fruits per branch, average weight and ripeness of the fruit, fruit weight gain) using wavelet analysis, during which each image obtained with a video camera located on a mobile robot, decomposes into wave functions. The training on the accumulation of experience of trial and error of the route by the robot was conducted and it was determined that with the accumulation of experience the number of unsuccessful attempts and time of the route decreases, while the number of received incentives increases.
The results of a statistical analysis of the distributions of the value of the fourth parameter of the Stokes vector (hereinafter the "phase parameter" – FP) of microscopic images of histological sections of kidney tissues with parenchymal morphological structure of the dead with varying degrees of blood loss are presented.
This paper investigates the relationship between the integral equation and Kirchhoff approximation in the diffraction theory of coherent radiance. The spectrum of the reflected wave is formed in the far field (Fraunhofer zone) and the solution is to Fourier transform of effective reflectance coefficient of a surface. In the paper, the analytical relationship between the method of solving an integral equation and the Kirchhoff approximation has been proven. It helps to define the structure of the field of diffracted waves in a Fraunhofer zone for coherent scattered light. The analytical equations for calculation of the average value of intensity scattering field and the mirror reflection coefficient of a rough surface have been obtained. Analysis of the components of the scattering coherent light coming from a metal surface has been improved. It helps to specify the data processing algorithms for evaluation of statistical characteristics of rough surfaces.
Artificial Intelligence may be used to solve complex technical and practical problems. Moreover, such Artificial Intelligence techniques as Fuzzy Systems, Artificial Neural Networks, Evolutionary and Genetic Algorithms have a great potential in providing optimization, prediction and management of communication system in a dynamic wireless environment. Artificial Intelligence approach provides optimized results in a challenging task of the call admission control process in cellular networks. The paper proposes a methodology for developing a genetic neuro-fuzzy controller for call admission in cellular networks. A structure of the access fuzzy controller was suggested. Linguistic variables, their terms as well as membership functions for input and output values were determined. A rule base was proposed. A Neuro-fuzzy System on the base of the fuzzy-controller was designed and simulated. A genetic algorithm was proposed for optimizing the rule base.

The paper deals with the fundamentals of the theory of photoreactive effect in bipolar and field-effect transistor structures. Photoreactive properties of semiconductor devices are widely used in a variety of radio electronics devices. Therefore, the study of these phenomena in bipolar transistor structures with negative resistance, allows us to create new sensory devices, which have better parameters than existing ones. The method of construction of radiomeasuring microelectronic transducers is offered on the base of photoreactive effect in sensing bipolar and field transistor structures, that has established premises for embodying transducers of optical radiation with a frequency output signal.
The application of the proposed mathematical tools, that can be used for signal processing self-generating transducers of physical quantities, are considered. Its operating mechanism is based on frequency modulation, when the frequency deviation depends on the intensity of exposure measurement parameter. It is shown that the action for leveling additive errors in the channel the signal generator is highly stable enough to use approximating second order polynomial.

Modern world achievements in the area of video-information output devices are analyzed, as optic-electronically geoinformation power system component, particularly the large image colored video screens. The lacks of the two-coordinate addressing system widespread which provide a minimum control channels by indicators are considered. The structures of the matrices light-emitting diodes typesetting video screens which there are no lacks of the addressing system are offered and problems concerning synthesis of video data visualization means based on logic-time functions as well as classic theory of controlling automatons.
