Javelin 3 is a software system for developing large-scale, fault tolerant, adaptively parallel applications. When all or part of their application can be cast as a masterworker or branch-and-bound computation, Javelin 3 frees application developers from concerns about inter-processor communication and fault tolerance among networked hosts, allowing them to focus on the underlying application. T...

An irregular activity on electric power distribution feeder, which does not draw adequate fault current to be detected by general protective devices, is called as High impedance fault (HIF). This paper presents the algorithm for HIF detection based on the amplitude of third and fifth harmonics of current, voltage and power. This paper proposes an intelligent algorithm using the Takagi SugenoKan...

In most arc fault circuit breakers, arc detection is accomplished through the signature analysis of remotely sensed branch currents, with high frequency spectral components being indicative of arcing. This paper presents an alternative approach based upon system identification. A model is assumed for the load on the distribution bus. This model is updated continuously by comparing measured volt...

Grid is an environment with millions of resources which are dynamic and heterogeneous in nature. A computational grid is one in which the resources are computing nodes and is meant for applications that involves larger computations. A scheduling algorithm is said to be efficient if and only if it performs better resource allocation even in case of resource failure. Resource allocation is a tedi...

Fault tolerance in cloud computing platforms and applications is a crucial issue. This issue is especially difficult since cloud computing relies by nature on a complex splitting into many layers. This paper analyses the implementation of fault tolerance in such a complex cloud computing environment with a focus on FCFS and SJF along with MPIL method with fault tolerance property. The proposed ...

In this paper, the effects of the accuracy of HV network parameters on calculated make and break fault levels are investigated. Fault level calculations, using computer models, are an approximation to the behaviour of the actual distribution network and, due to assumed parameter values, include a level of inaccuracy. The results of the fault level sensitivity analysis studies show that the netw...

Distributed Systems are useful for computation and storage of large scale data at dispersed location. Distributed File System (DFS) is a subsystem of Distributed System. DFS is a means of sharing of storage space and data. Servers, Storage devices and Clients are on dispersed location in DFS. Fault tolerance and Scalability are two main features of distributed file system. Performance of DFS is...

Byzantine fault-tolerant (BFT) replication has enjoyed a series of performance improvements, but remains costly due to its replicated work. We eliminate this cost for read-mostly workloads through Prophecy, a system that interposes itself between clients and any replicated service. At Prophecy’s core is a trusted sketcher component, designed to extend the semi-trusted load balancer that mediate...

In this paper, an adaptive sliding mode fault-tolerant control scheme based on prescribed performance and neural networks is developed for Unmanned Aerial Vehicle (UAV) quadrotor carrying a load to deal with actuator faults. First, nonsingular fast terminal (NFTSM) strategy presented. virtue of the proposed strategy, convergence high robustness can be guaranteed without stimulating chattering. ...
