The largest minimum weight of a self-dual doubly-even binary (n, k, d) code is d = 4n/24 + 4. Of such codes with length divisible by 24, the Golay Code is the only (24, 12, 8) code, the Extended Quadratic Residue Code is the only known (48, 24, 12) code, and there is no known (72, 36, 16) code. One may partition the search for a (48, 24, 12) self-dual… (More)
Exact and approximate algorithms for detecting lines in a two-dimensional image space are discussed. For the case of uniformly distributed noise within an image space, transform methods and different notions of probability measures governing the parameters of the transforms are described. It is shown that different quantization schemes of the transformed… (More)
The BLASTP program is a search tool for databases of protein sequences that is widely used by biologists as a first step in investigating new genome sequences. BLASTP finds high-scoring local alignments) without gaps between a query sequence and sequences in the database. The score of an alignment is the sum of the scores of individual alignments between… (More)
In this paper we show that a (22, 8, 4) design does not exist. This result was obtained by a computer search.
