1989 conference paper

General order moments in set theoretic estimation

International Conference on Acoustics, Speech, and Signal Processing, 2531–2534.

Event: International Conference on Acoustics, Speech, and Signal Processing at Glasgow, Scotland on May 23-26, 1989

TL;DR: A description is given of how information pertaining to an arbitrary absolute moment of the noise process can be used in a general set-theoretic estimation framework and it is shown that for each such piece of a priori information a set can be constructed in the solution space by constraining the corresponding sample statistics of the estimation residual to lie within some acceptable distance from the expected value.

1989 chapter

Mr. Smith goes to Las Vegas: Randomized parallel computation of the Smith Normal form of polynomial matrices

In Lecture Notes in Computer Science (pp. 317–322).

By: E. Kaltofen*, M. Krishnamoorthy* & B. Saunders*

TL;DR: The method employs randomization as a tool to remove the iterations along the main diagonal in the classical sequential algorithms, and as such might be useful in similar settings, as well as may speed the sequential methods themselves. (via Semantic Scholar)

1989 journal article

Computing greatest common divisors and factorizations in quadratic number fields

Mathematics of Computation, 53(188), 697–697.

By: E. Kaltofen* & H. Rolletschek*

TL;DR: It is shown that there does not even exist an input in these domains for which the GCD computation becomes possible by allowing nondecreasing norms or remainders whose norms are not as small as possible. (via Semantic Scholar)

1989 conference paper

An improved Las Vegas primality test

Proceedings of the ACM-SIGSAM 1989 international symposium on Symbolic and algebraic computation - ISSAC '89. Presented at the the ACM-SIGSAM 1989 international symposium.

Event: the ACM-SIGSAM 1989 international symposium

1989 journal article

Recursive mesh refinement on hypercubes

BIT, 29(2), 186–211.

Contributors: W. Gropp* & I. Ipsen*

TL;DR: A new form of Gray-code is described which is called aninterleaved Gray- code that allows easy labeling of graph nodes when the maximal level of refinement is unknown, allows easy determination of nearby nodes in the graph, is completely deterministic, and often distributes the graph uniformly across a hypercube.

From Bareiss' algorithm to the stable computation of partial correlations

Journal of Computational and Applied Mathematics, 27(1-2), 53–91.

Contributors: J. Delosme* & I. Ipsen*

TL;DR: A new algorithm is presented for the stable computation of sample partial correlation coefficients for symmetric positive-definite matrices B by generalizing Bareiss' algorithm for the solution of linear systems of equations with (non-symmetric) Toeplitz coefficient matrix to matrices that are not ToEplitz, and showing that it computes their LU and UL factorizations.
