In this paper, we propose a new fault-tolerant model for replication in distributed-file systems. We combine the advantages of the modular redundancy, primary-stand-by, and weighted priority schemes to address the fault-tolerant model. To fulfill the fault-tolerant requirements, we use the ideas of directoryoriented replication and the extended prefix table while incorporating a two-level heap ...

Purchase intention is the key to popularizing battery electric vehicles (BEVs) and to developing the industry. This study combines classical theoretical and qualitative research, and applies fault tree analysis (FTA) methods to study factors that hinder BEV purchase, and identify the logical relationship between top fault events and basic events, by calculating minimal cut sets and minimal path...

Current inversion condition leads to incorrect operation of current based directional relay in power system with series compensated device. Application of the intelligent system for fault direction classification has been suggested in this paper. A new current directional protection scheme based on intelligent classifier is proposed for the series compensated line. The proposed classifier uses ...

System fault-tree analysis is a technique for modeling dependability that is in widespread use. For systems that include software, the integration of software data into fault trees has proved problematic. In this paper we discuss a number of techniques that can be used to make the assessment of software dependability by testing both more tractable and more suitable for use in system fault-tree ...

The performances of almost all available fault tree analysis tools are limited by the performance of the prime implicant computation procedure they use. All these procedures manipulate the prime implicants of the fault trees explicitly, so that their complexities are directly related to the number of prime implicants to be generated. This paper presents a new analysis method of coherent as well...

The potential gains of deploying sensor networks for large scale applications are being realized. One of the basic operations in sensor networks is in-network aggregation. Among the various approaches to in-network aggregation, such as tree-based aggregation and gossip-based aggregation, the tree-based approaches have better performance and energy-saving characteristics. However, sensor network...
