Finite state machines, being a mathematical abstraction, allow you to perceive information from the control object, process it and give signals to control the object. The disadvantages of the representation of complex production systems by a set of finite state machines include the complexity of carrying out logical and set-theoretic operations on them and the complexity of describing the parallelism that occurs in the operation of complex production systems. When specifying a finite state machine in the matrix–predicate form, due to the information redundancy, it is possible to avoid these difficulties. Matrix–predicate method allows you to uniquely set the finite state machine square matrix, which makes it possible to use the methods of the theory of matrices during the set–theoretic operations on them and it is possible to avoid isomorphism. The paper presents the developed methods of representation of a finite state machine using a multi-place predicate, which greatly simplifies its task.

Mathematic modeling of the state of a thin round disk being heat and force affected is performed. In the central part of the disk the homogeneous field of temperatures is formed. Within the deformation theory of a perfect elasto-plastic solid the quadratic plasticity condition is chosen. The relationships between the radius of the disk, the temperature of the central part of the disk and the external pressure which defines the appearance of plastic zones have been established. For different values of external parameters of the model the stress vector hodograph and the plots of stresses and equivalent stresses have been introduced.

The problem of transmitting an image in a transmitter-receiver system over a noisy data transmission channel in JPEG 2000 and JPWL format under conditions of a previously unknown and varying intensity of noise is considered. This task is considered for the conditions of the IP network. The article aims to build methods for estimating the intensity of noise by the JPWL decoding results in the receiver and dynamically adapting the parameters of the JPWL transmitter to the current assessment of the noise intensity, ensuring the highest quality of the decoded image with the shortest length of the transmitted encoded stream. An experimental study of the relationship between the parameters of JPWL, the intensity of noise and the quality of the decoded image was carried out. It is shown that for any JPWL parameter there is a region of one-to-one correspondence between the percentage of fully recovered tiles and the probability of losing a network packet. A technique for estimating the intensity of noise by the decoding results of a single image is described. This technique can be expanded to use the results of decoding a series of images.

The article is devoted to the issue of improving the environmental safety of the construction industry by improving dust collectors of dust removal systems for the aspiration schemes of the construction industry/ It was proposed use additive-integrated dispersive analysis of variance of dust particles emissions throw out into the atmosphere by aspiration systems. The article proposes the improvement of complex analysis of variance using hydrodynamic criteria in output functions. Modified output data and additive-simplex allows getting approach to evaluate characteristics - equivalent sizes and speeds of sedimentation-soiling of dust particles with a higher degree of accuracy of the results. It makes possibility to determine the ranges of size’s and velocities’ changes with real ability. It is possible to obtain more reliable data of sedimentation rates and equivalent particle sizes for the studied dust samples of building materials using the distributions of the hydrodynamics criteria. Analytical approach to determining the density’ distribution of the numerical values of the hydrodynamics criteria in the output function allowed us to clarify the more real values of sedimentation rates and the equivalent particle sizes and the range of their changes both. This way analysis of variance of dispersed dust particles could call additive-complex or simplex approach. The obtained regressions in processing the research results were used in the development of devices for capturing dust of dispersed building materials from emissions. This way could significantly reduced dust leakage out from aspiration collectors of decreasing dust systems while purifying emissions at the building enterprises. This approach is one of the most effective ways to improve the environmental safety of the building industry.
