    Dethedetection of hulls requires the implementation of a built-in or autonomous provides a full range of functionalities for the detection and classification of transmitted sonar signals, generation of imitative signal with spatial parameters, analogous to those reflected by the seabed, and its radiation. This helps to model the shape, the sonar shadow and the reflective surface of the bottom mine in order to mask it by generating a packet simulating chaotic impulse disturbances with parameters corresponding to those of possible reflections from fictitious bottom objects and by re-emitting the received and additionally modeled hydro acoustic pulses with a calculated time lag to
    achieve the desired result

    The goal of this paper is to study algorithm for detection and classification of moving objects based on parameter estimates from their GPS signal shadow. The suggested algorithm uses satellite GPS signals to create radio barriers and to detect moving terrestrial targets. It can be examined as an algorithm for secondary application of the wireless technologies (SAWT). This technology is extremely modern and up-to-date and can find application in Industry 4.0 with regard to the reduction of the electromagnetic radiations. The GPS signals included shadow from several moving vehicles, processed in MATLAB environment in order to obtain the estimations of their parameters. In IBM SPSS Statistics, Scheffe test is used for classifying the moving objects. The results reveal that proposed signal processing of the GPS signal shadow combined with this statistical approach can be successfully applied in practice for object classification.

    In the last few years there has outlined a well-defined tendency to consider aviation security with regard to the optimal management of its level with the consistent solution of the identification, measurement, evaluation and decision-making problems. For this purpose aviation security is shown as a state related to the object’s under study defined parameters, the quantitative display of which in the dynamics of their changes under the influence of external and internal factors remains in acceptable limits in terms of the object’s operation. However, the environment is formed by the object’s safety equipment, which represent a definite list of technical and other functional elements, solving the problem of the internal and external factors countermeasure. If we consider the situation of counter-strategy as a pseudo field, the proposed model belongs to the class of boundary value problems described by partial differential equations. The problem has no analytical solution, and computational modeling is very limited by mathematical formalization’s issues. It is offered to use hybrid computer tools, which have undoubted advantages in this case.

    The main features of enterprise`s investment resources formation have been studied. A wide range of sources, tools and methods of investment activity funding and their impact on financial and business processes of industrial enterprises have been defined. It has been pointed out that enterprise`s capital directed to reinvestment can also act as the background of investment resources formation. Tendencies and forms of industrial enterprises` investment activity have been marked. The proposals about enterprise`s investment resources classification according to the main features have been made. This allows industrial enterprises to form investment resources taking into account their mobilization aimed at meeting goals or restructuring of enterprise`s financial tools portfolio.

    This paper attempts to provide a transparent and, if possible, a formal hierarchy of the main types of mathematical models used in the description of dynamic processes inside, at first glance, different systems. It is emphasized that the mathematical modeling is a natural and universal environment for effective analysis of system processes of different nature. From our point of view, the term "system analysis" means the methodology for classification of real systems (physical, biological, economic, social, etc.), which is based on the classification of mathematical models that are used to describe these systems.
