A key concept in comparing sequence collections is the issue of redundancy. The production of sequence collections free from redundancy is undoubtedly very useful, both in performing statistical analyses and accelerating extensive database searching on nucleotide sequences. Indeed, publicly available databases contain multiple entries of identical or almost identical sequences. Performing stati...

It has been suggested that the primary goal of the sensory system is to represent input in such a way as to reduce the high degree of redundancy. Given a noisy neural representation, however, solely reducing redundancy is not desirable, since redundancy is the only clue to reduce the effects of noise. Here we propose a model that best balances redundancy reduction and redundant representation. ...

Al~traet--All failure detection methods are based, either explicitly or implicitly, on the use of redundancy, i.e. on (possibly dynamic) relations among the measured variables. The robustness of the failure detection process consequently depends to a great degree on the reliability of the redundancy relations, which in turn is affected by the inevitable presence of model uncertainties. In this ...

Adopting classic redundancy-based fault-tolerant schemes in highly dynamic distributed computing systems does not necessarily result in the anticipated improvement in dependability. This primarily stems from statically predefined redundancy configurations employed within many classic dependability strategies, which as well known may negatively impact the schemes' overall effectiveness. In this ...

in the conventional design and analysis methods affecting parameters (loads, materials'strength, etc) are not set as probable variables. safety factors in the current codes andstandards are usually obtained on the basis of judgment and experience, which may beimproper or uneconomical. in technical literature, a method based on nonlinear static analysisis suggested to set reliability index on st...

one of the most important problems in the system reliability optimization is redundancy allocation problem that has been studied in different system configurations. k-out-of-n structure is a general system configuration and offers enhanced capabilities for analyzing more design problems. hence, in this paper, the redundancy allocation problem of k-out-of-n systems is studied. in the most previo...

This study is concerned with the introduction of synthesized speech into the humancomputer interface. A simulated hotel booking system is described which asks for information via either the screen or a DECtalk speech synthesizer. The degree of redundancy within the computer's response set is varied. The perceived 'friendliness' of the system increased with the use of synthesized speech incorpor...

Numerical graph theoretic invariants or topological indices (TIs) and principal components (PCs) derived from TIs have been used in discriminating a set of isospectral graphs. Results show that lower order connectivity and information theoretic TIs suffer from a high degree of redundancy, whereas higher order indices can characterize the graphs reasonably well. On the other hand, PCs derived fr...

It is well-known that biological and social interaction networks have a varying degree of redundancy, though a consensus of the precise cause of this is so far lacking. In this paper, we introduce a topological redundancy measure for labeled directed networks that is formal, computationally efficient and applicable to a variety of directed networks such as cellular signaling, metabolic and soci...
