Computer control of braking systems for freight trains " iii A fault tolerant architecture for brake-by-wire in railway cars ROGER JOHANSSON Abstract In this paper we will present a computer architecture suitable for distributed con...

This paper presents results for an automatic navigation system for agricultural vehicles. The system uses stereo-vision, inertial sensors and GPS. Special emphasis has been placed on modeling the natural environment in conjunction with a fault-tolerant navigation system. The results are exemplified by an agricultural vehicle following cut grass (swath). It is demonstrated how faults in the syst...

The reliable execution of a mobile agent is a very important design issue in building a mobile agent system and many fault-tolerant schemes have been proposed so far. To further develop mobile agent technology, reliability mechanisms such as fault tolerance and transaction support are required. For this purpose, we first identify two basic requirements for fault-tolerant mobile agent execution:...

we present an approach to design of fault tolerant computing systems. in this paper, a technique is employed that enable the combination of several codes, in order to obtain flexibility in the design of error correcting codes. code combining techniques are very effective, which one of these codes are turbo codes. the algorithm-based fault tolerance techniques that to detect errors rely on the c...

Recent articles predict that the quantum computing market will expand 500% by 2028. Billions of dollars are currently pouring into computer industry to build first fault-tolerant computers.

Self-stabilization for non-masking fault-tolerant distributed system has received considerable research interest over the last decade. In this paper, we propose a self-stabilizing algorithm for 2-edge-connectivity and 2-vertex-connectivity of an asynchronous distributed computer network. It is based on a self-stabilizing depth-first search, and is not a composite algorithm in the sense that it ...

It is widely agreed that building correct fault-tolerant systems is very difficult. To address this problem, this paper introduces a new model-based approach for developing masking fault-tolerant systems. As in component-based software development, two (or more) component specifications are developed, one implementing the required normal behavior and the other(s) the required fault-handling beh...

This paper proposed an observer based fault-tolerant control approach for the fuzzy T-S systems with sensors and actuators faults. By establishing the actuator fault and sensor fault models, an observer based fuzzy output feedback fault tolerant controller is developed and new stabilization conditions of the fuzzy fault tolerant control systems are given, which are formulated in terms of linear...

In this paper, we deal with two important issues in relation to modular reconfigurable manipulators, namely, the determination of the modular assembly configuration optimally suited to perform a specific task and the synthesis of fault tolerant systems. We present a numerical approach yielding an assembly configuration that satisfies four kinematic task requirements: reachability, joint limits,...
