This paper describes the methods used to take into account the nonlinearity of magnetic processes in the steel of an electric asynchronous machine. This is required for some cases when these physical processes play an important role in the accuracy of data. Justifications are presented that prove the need to approximate the magnetization curve of asynchronous machines to improve the quality of regulation of the electric drive, as well as improve control by energy criteria. Work at full load or near it leads to a decrease in the magnetization EMF due to a voltage drop in the stator, this must be taken into account. The article also shows the approach of applying the methods of accounting for saturation in synchronous machines for asynchronous using transformed equations.

The article presents a method for quantifying the survivability of information technology objects, in relation to the means of software and hardware impact, including those based on assessing the ratio of direct and indirect risks, the ratio of the probability of catastrophic failures for a damaged and intact system. The necessity of increasing the survivability of information technology facilities to ensure security in the global cyberspace is grounded. It is also necessary to note that to ensure the required level of integrated survivability of an information technology object, it is necessary to protect them from software and hardware impacts in the global cyberspace. Information-technical objects with high cyber-defiance are gradually destroyed, while maintaining limited performance (combat capability with respect to military systems). This allows you to take protective measures, thereby reducing the effects of exposure mainly to primary damage from damage to the elements of an information technology object. Information and technical objects with low survivability are destroyed sharply and catastrophically, which is accompanied by significant secondary and cascade destruction, which are disproportionate (disproportionate) initiating software and hardware effects.
