ABSTRACT

The article is devoted to solving the problems of developing new methods for qualitative diagnostics of underground pipelines of heat networks that take into account the specific features of wave propagation of acoustic signals through pipelines. A general methodological approach is presented. The approach includes the following steps: the formation of a diagnostic model of the pipeline section, taking into account the multi-wave propagation and wave interference; synchronous registration of the array of acoustic signals; calculating the arrays of their correlation functions; by correlation functions, calculation of arrays of diagnostic parameters sensitive to the interference of acoustic waves recorded at various points of the pipeline at the access points. Further, these parameters are used as control quality parameters in the nonlinear programming problem. Parameters are controlled in the process of solving a problem by choosing the spatial position of the sensors on the pipeline and the frequency ranges of the signals.

KEYWORDS

multi-wave propagation, vibrosignal, diagnostic model, correlation, pipeline, leakage, corrosion refinement.

ABSTRACT

The problem of the self-checking built-in checking circuits (concurrent error-detection systems) synthesis by the Boolean complement method of constant-weight codes is investigated. The restrictions on the structure of the components of concurrent error-detection systems are considered by the example of using the “1-out-of-3” code. It is shown that in addition to ensuring the testability of the Boolean complement and the checker in the control circuit, a testable implementation of the object of diagnosis and the check logic block are required. The conditions for ensuring totally self-checking of the concurrent error-detection system structure based on the method of Boolean complement to the “1-out-of-3” code is formulated. Examples illustrating the problem of testing the components and allowing to drawing conclusions about the possibility of using the Boolean complement method in the construction of self-checking discrete systems are given.

KEYWORDS

ABSTRACT

The operation of critical infrastructure objects in a specific environment such as cyberspace is associated with vulnerabilities and threats, and requires the development of new tools to ensure the sustainability of functioning in a computer attack. Management of the sustainability of the critical information infrastructure of the United Energy System of Ukraine is based on knowledge of the state of the objects of management, the state of the functioning environment and the effects that take place. An integral element of such control systems is a number of decision support subsystems. The capabilities of the management system directly depend on the ability of the decision support subsystem to provide the decision maker with a well-balanced information that characterizes the real and predicted states of the critical infrastructure objects and propose a reasonable choice of the trajectory for achieving the goal. In this regard, the development of a methodology for assessing the critical information infrastructure functioning in cyberspace is an urgent task.
