To theory of crystallization of nanomodified alloy

Abstract

Abstract. On the basis of thermodynamic approach, a mathematical model of nucleation and growth of the solid phase on highly activated wettable nanoseeds is proposed. New expressions for the free energy of formation and the rate of nucleation of crystallization centers on ultradispersed seeds (nanoparticles) obtained in the model take into account the influence of dimensional and capillary effects. Numerical experiments were carried out for Al+Si alloy modified with titanium nitride nanoparticles TiN. The results of the calculations were compared with the experimental data. The study is of interest for constructing a macroscopic model and understanding the mechanisms of structure formation in the case of heterogeneous crystallization of metals and alloys.

Intrusion and Anomaly Detection in Industrial Automation and Control Systems

“…Various incidents, malware examples and Advanced Persistent Threat (APT) campaigns targeting Critical Infrastructures (CI)s and IACS (summarized in Figure 2.3) are described in the literature [Anton et al, 2017] [Hemsley and Fisher, 2018] [Al-Hawawreh et al, 2019. For instance, Win32/Industroyer, one of the major publicly-disclosed real-world malware [Cherepanov, 2017] targeting SCADA systems, provides a good example of how recent malware can use multiple protocols in a coordinated campaign. Win32/Industroyer was specifically conceived for targeting SCADA protocols and affecting electric power systems.…”

“…The attack threats are highly heterogeneous and complex, which demands more collaborative and orchestrated anomaly detection techniques. 20 [Cherepanov, 2017] [Slowik, 2018).…”
