in this paper the design and implementation of fault tolerable architecture for scientific workflow engines is presented. the engines are assumed to be implemented as composite web services. current architectures for workflow engines do not make any considerations for substituting faulty web services with correct ones at run time. the difficulty is to rollback the execution state of the workflo...

In this paper, the fuzzy system has been used for fault detection and diagnosis of a yeast fermentation bioreactor based on measurements corrupted by noise. In one case, parameters of membership functions are selected in a conventional manner. In another case, using certainty factors between normal and faulty conditions the optimal values of these parameters have been obtained through the g...

This document describes the header compression mechanisms for the IPsec [RFC4301] based on the encoding scheme standardized in [RFC6282]. The IPsec Authentication Header (AH) and Encapsulated Security Payload (ESP) headers are compressed using Next Header Compression (NHC) defined in [RFC6282]. This document does not invalidate any encoding schemes proposed in 6LoWPAN [RFC6282] but rather compl...

This paper presents a novel approach to fault detection, faulty phase(s) identification, faulty section estimation, and fault location determination for a multi-ended transmission line in Egypt based on artificial neural networks. In order to perform this approach, the protection task is subdivided into different neural network modules for fault detection, fault classification as well as fault ...
