The reliability of ADCs used in highly critical systems can be increased by applying a two-step procedure starting with sensitivity analysis followed by redesign. The sensitivity analysis is used to identify the most sensitive blocks which could then be redesigned for better reliability by incorporating fault tolerance. This paper illustrates the steps involved in incorporating fault tolerance ...

The modification of weighted checksum method is proposed, which allows to derive the fault tolerant versions of most linear algebra algorithms. The purpose is detection and correction of calculation errors occurred due to transient hardware faults. Using the proposed method, the fault-tolerant version of Faddeeva algorithm is designed in this paper. The computational complexity of new algorithm...

Quantifying faults in manufacturing processes is a crucial concern, particularly in new manufacturing processes where continual product improvement is desired. We present an approach to incrementally diagnose fault patterns on surfaces of product components. Contemporary experimental and surface-analysis techniques are adapted at each step of the approach. Specifically, a maturing layeredmanufa...

In this paper, we study the problem of constructing a sorting circuit, network, or PRAM algorithm that is tolerant to faults. For the most part, we focus on fault patterns that are random, i.e., where the result of each comparison is independently faulty with probability upper-bounded by some constant. All previous fault-tolerant sorting circuits, networks, and parallel algorithms require (log ...

Agent integrity verification and fault-tolerance are the two prevalent methods among the solutions to the Problem of Malicious Hosts in Mobile agent system. Agent integrity verification enables the owner of the agent to detect upon its return whether a visited host has maliciously altered the state of the agent based on agent integrity verification [6]. A known drawback of such method is that i...

Some of the most widely-investigated control charting techniques for autocorrelated data are based on time series residuals. If the mean shift in the autocorrelated process is a sudden step shift, the resulting mean shift in the residuals is time varying and has been referred to as the fault signature. Traditional residual based charts, such as a Shewhart, CUSUM, or EWMA on the residuals, do no...

We address the problem of modifying a hypercube computer by the addition of spare nodes and links to improve its fault tolerance, while maintaining a specified level of performance. The hypercube is modeled by a graph in which nodes represent processors and edges represent communication links. A new graphbased measure of performance degradation is introduced. This characterizes a fault-tolerant...

We describe a new variant of the well known Baby-Step Giant-Step algorithm in the case of some discrete logarithms with a special structure. More precisely, we focus on discrete logarithms equal to products in groups of unknown order. As an example of application, we show that this new algorithm enables to cryptanalyse a variant of the GPS scheme proposed by Girault and Lefranc at CHES 2004 con...

Giant clams (Tridacnidae) are known to live in association with photosynthetic single cell dinoflagellate algae commonly called zooxanthellae. These algae which can be found in the mantle of the clams are capable of transferring part of their photosynthates which become an important source of energy to the host ( apart from filter feeding activity). In order to understand the basic biological p...
