Fault tolerance is a key aspect of the dependability of complex computer-based systems. Fault tolerance may be difficult to measure directly in complex real world systems, and we propose here to measure it in terms of integrity preservation of the system under the assumption of a particular fault occurrence distribution. We measure the integrity preservation ability of the system by measuring t...

Fault tolerance property of artificial neural networks has been investigated with reference to the hardware model of artificial neural networks. Weight fault is an important link, which causes breakup between two nodes. In this paper weight fault has been explained. Experiments have been performed for Weight-stuck-0 fault. Effect of weight-stuck-0 fault on trained network has been analyzed in t...

A component-based software architecture is presented to support the process of designing and developing fault-tolerant computerised control systems. To this end, we combine an idealised fault-tolerant component, the C2 architecture style and protective wrappers, and embed fault tolerance techniques into component definitions. The resulting architecture is described by normaland abnormal-activit...

Fault tolerance is one of the most important means to avoid service failure in the presence of faults, so to guarantee they will not interrupt the service delivery. Software testing, instead, is one of the major fault removal techniques, realized in order to detect and remove software faults during software development so that they will not be present in the final product. This paper shows how ...

In this paper, model predictive control (MPC) problem with fault-tolerance capabilities is formulated within the hybrid systems framework. In particular, the mixed logical dynamic form to represent hybrid systems is considered. Using this approach, a hybrid model of the system to be controlled is obtained, which includes inherent hybrid phenomena and possible modes caused by faults occurrence. ...

The fault tolerance theories by Arora and Kulkarni [3] and by Jhumka et al. [10] view a fault-tolerant program as the result of composing a fault-intolerant program with fault tolerance components called detectors and correctors. At their core, the theories assume that the correctness specifications under consideration are fusion closed. In general, fusion closure of specifications can be achie...

This project proposes a fault-tolerant solution for a buffer less network-on-chip, including an on-line fault-diagnosis mechanism to detect both transient and permanent faults, a hybrid automatic repeat request, and forward error correction link-level error control scheme to handle transient faults and a reinforcement-learningbased fault-tolerant deflection routing (FTDR) algorithm to tolerate ...

In this paper, we show how artificial evolution can be used to improve the fault-tolerance of electronic circuits. We show that evolution is able to improve the fault tolerance of a digital circuit, given a known fault model. Evolution is also able to create sets of different circuits that, when combined into an ensemble of circuits, have reduced correlation in their fault pattern, and therefor...

An increasing number of applications are demanding real-time performance from their multiprocessor systems. For many of these applications, a failure may produce disastrous results. Such failures are avoided in hard real-time systems by the use of fault-tolerance. In hard real-time multiprocessor scheduling, this fault tolerance may be provided by including several task backups in each schedule...

The Object Management Architecture (OMA) has been recognized as a de facto standard in the development of object services in distributed computing environment. In a distributed system, the provision for failure-recovery is always a vital design issue. However, the fault-tolerant service has not been extensively considered in the current OMA framework, despite the fact that a increasing number o...
