We construct many Euclidean and Hermitian self-dual MDS (or near MDS) codes of length up to 12 over finite fields GF(q), where q = 8, 9, 16, 25, 32, 41, 49, 53, 64, 81, and 128.Expand

Abstract. We present two kinds of construction methods for self-dualcodes over F 2 + u F 2 . Specially, the second construction (respectively,the rst one) preserves the types of codes, that is, the… Expand

The predominant microorganisms in samples taken from shower heads in residences in the Korean city “N” were Stenotrophomonas maltophilia, Sphingomonas paucimobilis, Acidovorax temperans, and… Expand

We present an efficient method for constructing self-dual or self-orthogonal codes over finite rings Z"p"^"m (or Z"m) with p an odd prime and m a positive integer.Expand

We complete the building-up construction for self-dual codes by resolving the open cases over $GF(q)$ with an odd prime $p$ satisfying $p \equiv 3 \pmod 4$ with $r$ odd.Expand
