As new and interesting peer-to-peer applications combine with advancements in networking technology, they are reaching millions of users across the globe. Numerous studies have shown, however, that loss of connectivity is common on the wide-area network, due to hardware and software failures, and network misconfigurations. Despite the natural redundancy present in underlying network links, the ...

An application of development of fault tolerant control (FTC) system for condensation turbine has been presented in the paper. The tolerance of instrument faults has been achieved by the use of functional redundancy which consists in performance of appropriate changes in the operation manner of the faulty system. The method of fuzzy neural networks (FNN) has been used for fault detection and is...

A novel and highly efficient design of a Software defined radiation tolerant baseband module for a LEO satellite telecommand receiver using FPGA is presented. FPGAs in space are subject to Single Event Upsets (SEUs) due to high radiation environment. Traditionally, Triple Modular Redundancy (TMR) is used for mitigating Single Event Upsets (SEUs). The drawback of using TMR is that it consumes a ...

We present a novel scheme to the coverage problem, introducing a quantitative way to estimate the interaction between a block an its environment. This is achieved by setting a discrete version of Green’s Theorem, specially adapted for Model Checking based verification of integrated circuits. This method is best suited for the coverage problem since it enables one to quantify the incompleteness ...

Dynamic thread duplication is a known redundancy technique for multi-cores. The approach duplicates a thread under observation for some time period and compares the signatures of the two threads to detect errors. Hybrid multi-cores, typically implemented on platform FPGAs, enable the unique option of running the thread under observation and its copy in different modalities, i.e., software and h...

Database normalization theory offers formalized guidelines how to reduce data redundancy and thus problems that it causes in databases. More lately, researchers have started to formalize ideas that the problems caused by unwanted dependencies and redundancy can be observed in case of any modular system like software, hardware, or organization. To tackle these problems, they have proposed the th...

The SPring-8 controls network has maintained accelerator operations in high reliability and shown good performance during the past years. To cope with the increase of loads on the network due to faster data acquisition and the addition of equipment data, networking hardware has been installed in the last few years. The upgraded network replaces the original FDDI backbone and switches with mixed...

Redundancy based on a parity encoding has been proposed for insuring that disk arrays provide highly reliable data. Parity-based redundancy will tolerate many independent and dependent disk failures (shared support hardware) without on-line spare disks and many more such failures with on-line spare disks. This paper explores the design of reliable, redundant disk arrays. In the context of a 70 ...

By adding redundancy to transmitted data, error-correcting codes (ECCs) make it possible to communicate reliably over noisy channels. Minimizing redundancy and (de)coding time has driven much research, culminating with LowDensity Parity-Check (LDPC) codes. At first sight, ECCs may be considered as a trustful piece of computer systems because classical results are well-understood. But ECCs are a...
