Special interest in designing, constructing and exploitation of fault tolerant systems is connected with the need of attending to critical infrastructure systems. In this paper we focus on presentation and analysis of the requirements demanded on the context of fault tolerance assurance in the critical infrastructure systems. Especially, we take into consideration algorithmical and topological ...

For non-affine nonlinear flight control systems, a non-affine nonlinear robust fault tolerance control method is proposed. Here, the fault tolerance control framework is used, and on this basis, observer-based auxiliary system is designed to implicit fault parameters and disturbances information. Then reconfigurable controller is designed using the dynamic of observer-based auxiliary system, wh...

We present a survey of different techniques used by the authors to transform a security or fault-tolerance problem into another with a known solution. We consider the following two cases: (1) reducing a security problem into a fault-tolerance problem; (2) reducing a fault-tolerant problem into its fault-intolerant version. In these cases it is possible to reuse known solutions to construct new ...

This paper describes FTAPE (Fault Tolerance And Performance Eval-uator), a tool that can be used to compare fault-tolerant computers. The major parts of the tool include a system-wide fault injector, a workload generator, and a workload activity measurement tool. The workload creates high stress conditions on the machine. Using stress-based injection, the fault injector is able to utilize knowl...

In component-based systems, fault-tolerance concerns are typically handled by manually programmed fault containers. The purpose of fault containers is to prevent error propagation across component boundaries by means of redundant service providers. However, manually programmed fault containers are often subject to evolutionary pressure when components change. In this paper we present a meta-lev...

We present a new approach to fault tolerance for High Performance Computing system. Our approach is based on a careful adaptation of the Algorithm-Based Fault Tolerance technique [K. Huang, J. Abraham, Algorithm-based fault tolerance for matrix operations, IEEE Transactions on Computers (Spec. Issue Reliable & Fault-Tolerant Comp.) 33 (1984) 518–528] to the need of parallel distributed computat...

To come over these issues there are many techniques like software/ code refactoring, software clustering, replication and software fault tolerance but this research says that applying software/ code refactoring techniques and software fault tolerance to reduce the chances of availability issue, failure cause, application fault and error, and performance and scalability issue in web application,...

This paper considers the ability of an evolved circuit to acquire fault tolerance by including fault conditions within the fitness measure of the evolutionary process. A simple oscillator circuit, implemented on a Xilinx FPGA, showed a 12 fold increase in fault-tolerance when compared to a control oscillator using realistic faults.

I revisit the fault-tolerance of cyclic redundancy checks (CRCs), expanding on the work of Driscoll et al [1]. I introduce the concepts of Schrödinger-Hamming weight and Schrödinger-Hamming distance, and I argue that under a fault model in which stuck-at-one-half or slightly-out-of-spec faults dominate, current methods for computing the fault detection of CRCs may be over-optimistic. Keywords-c...

Abstract. Parallelism in file systems is obtained by using several independent server nodes supporting one or more secondary storage devices. This approach increases the performance and scalability of the system, but a fault in one single node can make the whole system fail. In order to avoid this problem, data must be stored using some kind of redundant technique, so that it can be recovered i...
