When we transmit data over a noisy channel (e.g., satellite) to a receiver, we run the risk of our data becoming corrupted. Fixing the channel is not typically an option, so instead we must make our data noise-proof. A naive method of doing this is simply sending the same data multiple times. However, the benefit of the redundancy created may be offset by the cost of sending a lengthy message m...
متن کاملMr. Neville Chamberlain's Opportunity
Sir.?The aims of your paper in regard to the public health, as set out in your New Year's issue, are excellent. And as everyone seems to be waking up at last to the fact that the housing question overshadows every other question in domestic politics, perhaps something will be accomplished. Questions of housing and health must not, however, be allowed to become the playthings of politics. Every ...
متن کاملNeville Hudson: Evolutionary Biology of the Bivalvia
The long history of both zoological and palaeontological research on the bivalves has revealed a startling degree of convergence and parallel evolution which has hampered the interpretation of their evolutionary history. However new discoveries and developments make it timely for a new concerted effort to integrate zoological and palaeontological techniques to improve comprehension of the evolu...
متن کاملMultivariate polynomial interpolation: Aitken-Neville sets and generalized principal lattices
A suitably weakened definition of generalized principal lattices is shown to be equivalent to the recent definition of Aitken-Neville sets. The recent paper [CGS08] explores the relationship of Aitken-Neville sets, introduced in [SX], to generalized principal lattices, introduced in [CGS06]. Both are subsets X of F (with F equal to R or C) that are n-correct for some n in the sense that, with Π...
متن کاملA PLU-factorization of rectangular matrices by the Neville elimination
In this paper we prove that Neville elimination can be matricially described by elementary matrices. A PLU-factorization is obtained for any n×m matrix, where P is a permutation matrix, L is a lower triangular matrix (product of bidiagonal factors) and U is an upper triangular matrix. This result generalizes the Neville factorization usually applied to characterize the totally positive matrices...
