We present the design, prototype implementation and initial evaluation of FedFS a novel cluster file system architecture that provides a global file space by aggregating the local file systems of the cluster nodes into a loose federation. The federated file system (FedFS) is created ad-hoc for a distributed application that runs on the cluster, and its(More)
Future automobiles will be equipped with x-by-wire systems to improve reliability, safety, and performance. The fault-tolerant capability of these systems is crucial due to their safety critical nature. Three fault-tolerant inverter topologies for permanent magnet brushless direct current motor drives suitable for automotive x-by-wire systems are analyzed.(More)
Protocols like the Direct Access File System (DAFS) leverage user-level memory-mapped communication to enable low overhead access to network-attached storage for applications. DAFS offers significant improvement in application performance using features like direct data transfer and RDMA. Our goal is to build high performance network file servers using(More)
This work describes the main consideration in the design of power converter for a SRM drive with the particular attention to the choice of converter topology, and to study and develop the static and dynamic characteristics of the prototype model of SRM using FEA software (MagNet 6. 22). To simulate the power converter switching circuit for prototype model(More)
Navy Shipboard Power Systems have different characteristics when compared with utility power systems. To conduct system studies on shipboard power systems, an effective simulation tool is required to model the Shipboard Electric Power Systems. This paper presents the results of the analysis of three popular simulation tools, ATP, PSpice and Saber for(More)
Multicasting is one of the fast and simple ways of transmitting a same data to multiple people at the same time in the network which saves the transmission time. Since multicasting is taking part of transmitting to multiple people there are chances for creating vulnerability against various attacks. In the existing system, MKMP - Multicast Key Management(More)
Data Collection schemes fail to supply a secure reliable network in terms of quality, traffic, and end-to-end affiliation. during this paper, a Improved rate Energy-efficient and Link-aware Cluster-Tree (IVELCT) theme for knowledge assortment in WSNs is projected which might effectively mitigate the issues of coverage distance, mobility, delay, traffic,(More)
A series of new 3-(4-methylcoumarinyl-7-oxymethyl)-6-substitutedphenyl-5,6-dihydro-s-triazolo (3,4-b)(1,3,4)-thiadiazoles 2(a-j) have been synthesized by reacting 5-(4-methyl coumarinyl-7-oxymethyl)-4-amino-3-mercapto(4H)-1,2,4-triazole with various aromatic aldehydes by microwave assisted organic synthesis. The structure of the compounds 2 (a-j) has been(More)
Federated DAFS is our approach to federate DAFS servers using memory-mapped communication. Federated DAFS combines an efficient user-space DAFS implementation with a low overhead clustering layer to present a scalable clustering solution for DAFS servers. In this paper, we describe the location independent global naming scheme used to federate DAFS servers.(More)
