One objective of studying complex system reliabilities using block diagrams is to determine which individual components contribute most significantly to the reliability of the assembled system. A well-known method is to compute the Birnbaum component importance (BCI) of every component, then prioritize reliability improvement efforts on the components that have larger importance values. In the literature...
We propose a new dual-level fault injection method for evaluating combination effect of single event upsets (SEUs) and single event transients (SETs). The proposed interaction method allows collaborative simulation on register-transfer level (RTL) and gate level. Conventional fault injection methods or fault model techniques typically aim at SEUs or SETs, rather than the combination of SETs and SEUs...
This paper presents a warranty forecasting system that forecasts future failure counts, multiple periods ahead, from the production of a non-repairable product, which enters the field as staggered groups of units. Warranty data analysis is a vast research area. Even warranty forecasting may involve many different scenarios. We focus on the most common scenario and study the issues that appear during...
This paper proposes a new modeling approach which can be applied to solve some practical reliability engineering problems when competing failure modes present, but only one or limited failures have occurred. This type of failure data cannot be modeled by traditional time-to-failure distributions. The new approach is derived from Weibayes method and provides a viable solution when reliability inference...
Object storage system provides ocean space to hold a very large amount of data objects reliably and guarantee the clients to efficiently obtain their big data. In this paper, we propose a secure provable data possession scheme for object storage system, so as to enhance the security and efficiency through interactive verification and hierarchical structure optimizing. In particular, a new secure protection...
System reliability models play an important role in the reliability engineering. In order to meet the application, so far there are more than one hundred models. With the development of modern complex networks, reliability is an important criterion due the fact that failure of these networks affects its users adversely The directed tree network system is one of many network systems which are used...
As ontology is subjective and varies in different domains, the amount of ontologies turns out to be huge but with poor compatibility. Mainstream method for ontology integration is mostly achieved by establishing mappings between ontologies. In this essay, the author put forward another way of ontology merging. After statistic machine learning on concept relations, the frequency of different ontologies...
This paper describes an intelligent circuit breaker software and hardware design, real-time multi-task alarm system will be introduced into circuit breaker monitoring and control, to the timely opening and timely alarm. According to the different impact parameters, the different alarm information was given, increasing the protection and alerts function of the circuit.
Safety and availability are issues of major importance in many critical systems. A RTOS (realtime operating system)-integrated fault-tolerant system using TMR technology is presented in this paper. The system incorporates three homogeneous microcomputers and provides the fault-tolerant function through system-APIs to applications. As it is integrated with RTOS, the system is more general-purpose,...
In this paper, the finite element method is used to calculate the three-dimensional electric-field distribution of long-rod post porcelain insulators used in 1000 kV system. The electric-field distribution is simulated in the condition of varied position, varied major radius and varied section dimension of the shielding ring. The effect of these factors to the external insulation characteristics of...
