This paper introduces the gray clustering theory as a method to conduct an information security risk assessment for power substation communication systems using the gray theory with combination of AHP and Delphi method, and improves the substation communication system information security risk assessment model based on the gray clustering theory. Analysis albino gray clustering by constructing weight...
Based on application conditions of CRH EMUs wheel-set, a more strictly ultrasonic inspection for online wheel-set is required. To find an optimized solution, phased array ultrasonic testing technology mixed with conventional ultrasonic testing technology is studied. In this article, multi probes arrangement on wheel tread and inner wheel rim are designed, and their ultrasonic fields in wheel rim &...
This paper begins with a discussion of the role and value of industrial control system (ICS) test bed which apply a universal, controllable, realistic, and repeatable experimental platform to SCADA control system cyber security research. According to ICS layered architecture, ICS test bed based on emulation, physical, and simulation (EPS-ICS Test bed) is designed and implemented. EPS-ICS Test bed...
Composable modeling enables the rapid, efficient and flexible assembly of simulation systems from components. To data there is a lack of formal descriptions for the process of composable modeling or composable modeling approaches are not operable in engineering. In view of the existing problems, a composable modeling approach based on Petri nets was proposed. Petri nets formal definition of component...
