Concurrently, a symbolic approach for analog system-level fault diagnosis and a systematic approach to maximize the fault location capability are proposed. This unified approach is realized as a result of combining the simulation before test (SBT) fault dictionary diagnosis method with a symbolic approach. The traditional SBT fault dictionary method is often costly and inefficient because of a ...

Advanced Encryption Standard (AES) cryptographic system are widely used in embedded systems to secure secret information. One of the most powerful cryptanalysis techniques against the cryptographic systems is the fault injection attacks. The complexity of cryptographic systems is increasing which requires fast security attacks simulation against fault injection attacks. The multi-level Electron...

A new method for mixed level fault simulation of Data-Paths in Digital Systems represented with Decision Diagrams (DD) is proposed. We suppose that a register transfer level (RTL) information along with gate-level descriptions for RTL blocks are available. Decision diagrams (DDs) are exploited as a uniform model for describing circuits on both levels. The physical defects in the system are mapp...

Transmission lines are designed to transfer electric power from source locations to distribution networks. This project investigates the problem of fault localization using traveling wave voltage and current signals obtained at a single end of a transmission line and multi ends of a transmission network. Fourier transform (FT) is the most popular transformation that can be applied to traveling ...

A new method for state justiication is proposed for sequential circuit test generation. The linear list of states dynamically obtained during the derivation of test vectors is used to guide the search during state justiication. State-transfer sequences may already be known that drive the circuit from the current state to the target state. Otherwise, genetic engineering of existing state-transfe...

Dissolved gas analysis (DGA) is a reliable technique for detecting the presence of incipient fault conditions in oil immersed transformers. In this method the presence of certain key gases is monitored. The various analysis methods are : Rogers ratio, IEC ratio, Doernenburg, Duval triangle, key gas, artificial neural network (ANN) method. In this paper the various DGA methods are evaluated and ...

society is growing increasingly dependent upon large-scale, highly distributed systems that operate in unbounded open network environments. unless safeguards are incorporated in the system, a failure of even a single component, e.g. a link or a node, can significantly impact the network performance and can cause highly expensive damages. the discipline of survivability attempts to ensure that n...

Many existing clusters use inexpensive Gigabit Ethernet and often have multiple interfaces cards to improve bandwidth and enhance fault tolerance. We investigate the use of Concurrent Multipath Transfer (CMT), an extension to the Stream Control Transmission Protocol (SCTP), to take advantage of multiple network interfaces for use with MPI programs. We evaluate the performance of our system with...

The Eternal system enhances the CORBA standard to provide fault tolerance within distributed systems that are susceptible to network partitioning. Fault tolerance is achieved through consistent replication of both client and server objects. Objects may be actively or passively replicated, and replicated objects of both types may coexist. Nested operations involving both active and passive objec...

We are proposing to develop a fault-tolerant distributed computing and database system for use in High Energy Physics, but applicable to other disciplines. This system will allow us to solve the challenging problem of data processing, analysis and simulation by exploiting developments in distributed systems, fault tolerance, high performance networks and database technology. We will extend the ...
