Fault tolerance is an obligatory feature in safety critical applications (aeronautical, aerospace, medical and military applications, power plants, etc.), where loss of life, environmental disasters, equipment destructions or unplanned downtimes must be avoided. For such applications, a novel bio-inspired motion control system is proposed. All its three components (the switched reluctance machi...

This paper describes a new CAD tool, FTROM — Fault-Tolerant ROM compiler, which synthesizes layout geometries of fault-tolerant ROM modules with flexible, user-specified geometry and CMOS design-rule parameters. This physical design tool produces high-quality built-in self-testable (BIST) and fault-tolerant ROM layouts and uses a novel, minimum-delay overhead approach for fault-tolerance. A too...

Reliability enhancement in software system is a crucial and challenging issue. Applying efficient fault-tolerant mechanism can fulfill the system reliability requirement. This paper proposes reliability models for hierarchical and hybrid fault-tolerant software systems considering failure dependencies or related faults in software components/versions. Our system models are based on the classica...

This article presents a novel fault-tolerant technique which is based on the previously introduced Modulus Replication Residue Number System (MRRNS). Using the MRRNS mapping technique, we are able to compute using modular arithmetic over identical channels. We can make this system fault tolerant by increasing the number of channels, but by using some elementary polynomial properties we are able...

In this paper, fault tolerant compensation for non-linear plants is addressed. Soft fault detection and isolation is performed for a partial sensor fault detection. New method is proposed that combine model predictive controllers with fuzzy Takagi-Sugeno models. An example is presented that illustrates the functionality of the proposed method. Keywords— Fault tolerant control, Fault detection a...

This paper analyses the previous work done in the field of fault tolerant localization and tracking in wireless sensor network (WSN) using binary data. Many previous systems use only binary data for communication in the WSN in the area of fault tolerant localization and tracking. Fault tolerance is the property of wireless sensor nodes to accept the particular amount of fault in localization an...

Next to the high performance, the most important feature of the multiprocessor systems is their fault tolerant capability. In this regard, fault tolerant interconnection networks and specially fault tolerant routing methods are important parts of these systems. Hypercube is a popular interconnection network that is used in many multiprocessors. There are a number of suggested methods for fault ...

Fault-tolerant programs are typically not only difficult to implement but also incur extra costs in terms of performance or resource consumption. Failures are typically relatively rare but the fault-tolerance overhead must be paid regardless if any failures occur during the program execution. This paper presents an approach that reduces the cost of fault-tolerance, namely, adaptations to a chan...

In engineering application the sensor or actuator fault will lead to seriously damage to mechanical systems. The research of sensor or actuator fault diagnosis and fault-tolerant control is very important to improve the safety and reliability of the system. The paper investigates the fault diagnosis and fault-tolerant methods of vehicle suspension system with Magnetorheological (MR) dampers (ac...

In this paper, we study the problem of constructing a sorting circuit, network, or PRAM algorithm that is tolerant to faults. For the most part, we focus on fault patterns that are random, i.e., where the result of each comparison is independently faulty with probability upper-bounded by some constant. All previous fault-tolerant sorting circuits, networks, and parallel algorithms require (log ...
