In the nuclear power engineering, methods of detection failures and diagnostics, as well as systems of information support of operators in the order of improving the safety and reliability of the operation play an increasing role. A task that is solved within the information support system is the task of calculating technical and economical indexes and its connection with the assurance of the normal operation mode of nuclear power plants. The technical and economical indexes characterize the efficiency, faultness, and durability of the power equipment in its operation process. On the basis of the information task of calculating the technical and economical indexes, objective information on the technological processes run efficiency and actual power equipment is obtained. Conditions of optimal NPP performance are determined in the process of its technical and economical indexes analysis. So, the analysis of these indexes is one of the most important tasks of the NPP APCS. The information task of calculating the technical and economical indexes in the real-time on the basis of the intelligent data analysis and models of predicting the risk potential of the critical infrastructure will enable one to prevent approaching the technological process to critical modes.

We study the behavior of the soliton that encounters a barrier with dissipation while moving in a nondissipative medium. We use the Korteweg–de Vries–Burgers equation to model this situation. The modeling includes the case of a finite dissipative layer similar to a wave passing through air–glass–air and also a wave passing from a nondissipative layer into a dissipative layer (similar to light passing from air to water). The dissipation predictably reduces the soliton amplitude/velocity. Other effects also occur in the case of a finite barrier in the soliton path: after the wave leaves the dissipative barrier, it retains the soliton form, but a reflection wave arises as small and quasiharmonic oscillations (a breather). The breather propagates faster than the soliton passing through the barrier.

Stress state of Mars is estimated using the static method (or loading factors technique). Calculations are applied for a test interior structure model M_50 with lithosphere 300 km.

We identify the main stages of intelligent analysis of the pulse signal of the radial artery, used to obtain a set of informative parameters in medical diagnostic problems for various diseases. We show the results of expert and formalized classifications of the parameters of the analyzed signal, including the parameters of the shape of the pulse wave within the main quasiperiod and parameters that determine the rhythmic structure of the signal. We develop a multi-stage scheme for obtaining a set of informative parameters of the pulse signal that allows to take into account their characteristic features. The effectiveness of the developed approaches is demonstrated with the example of the problem of diagnosing early stages of arterial hypertension.

The ways of plant’s product and energy flows measurement are discussed. The algorithms of computing cumulative flowrates within the specified time interval and error estimation formulae are included.This article continues consideration of features of estimates of the main KPI of work of production of technological type. In the previous article [1] features of estimates of qualitative indexes of production products were described. Features of estimates of quantitative indices of the products are given in this article.
