Traditional modular redundancy based upon software fault tolerance techniques, such as N-version programming and recovery blocks, is now widely known and its use is on the increase. By contrast, data fault tolerance techniques have been largely ignored. The most likely reason for this omission is the perception that implementations are highly complex. Fortunately this situation has been greatly...

this study was conducted to determine drought tolerance genotypes with superiority in different stressed environments. to screening quantitative indices of drought tolerance, genotypes of safflower (carthamus tinctorius l.) were tested in a complete randomized block design with three replications under two different water regimes (irrigated and rainfed). significant positive correlation was fou...

in order to comparison and determination of the best drought tolerance indices in sweet corn hybrids, an experiment was conducted using a randomized complete block design in split plot lay out with three replications at seed and plant improvement institute in karaj in 2006. three irrigation levels (irrigation after 75 as control, 100 and 125 millimeters cumulative evaporation from class a evapo...

Fault tolerance is a key factor of industrial computing systems design. But in practical terms, these systems, like every commercial product, are under great financial constraints and they have to remain in operational state as long as possible due to their commercial attractiveness. This work provides an analysis of the instantaneous failure rate of these systems at the end of their life-time ...

Highly optimized tolerance (HOT) was recently introduced as a conceptual framework to study fundamental aspects of complexity. HOT is motivated primarily by systems from biology and engineering and emphasizes, (i) highly structured, nongeneric, self-dissimilar internal configurations, and (ii) robust yet fragile external behavior. HOT claims these are the most important features of complexity a...

Masking fault-tolerance guarantees that programs continually satisfy their specii-cation in the presence of faults. By way of contrast, nonmasking fault-tolerance does not guarantee as much: it merely guarantees that when faults stop occurring, program executions converge to states from where programs continually (re)satisfy their speciication. We present in this paper a component based method ...
