Compression of periodic complementary sequences and applications
DŽ Ɖoković, IS Kotsireas - Designs, Codes and Cryptography, 2015 - Springer
A collection of complex sequences of length vv is complementary if the sum of their periodic
autocorrelation function values at all non-zero shifts is constant. For a complex sequence A …

Symmetric Hadamard matrices of order 116 and 172 exist
O Di Matteo, DŽ Ðoković, IS Kotsireas - Special matrices, 2015 - degruyter.com
We construct new symmetric Hadamard matrices of orders 92, 116, and 172. While the
existence of those of order 92 was known since 1978, the orders 116 and 172 are new. Our …

Direct construction of globally D‐optimal designs for factors at two levels and main effects models
In develo** screening experiments for two‐level factors, practitioners typically are familiar
with regular fractional factorial designs, which are orthogonal, globally D‐optimal (ie, 100 …

Some new periodic Golay pairs
DŽ Ðoković, IS Kotsireas - Numerical Algorithms, 2015 - Springer
Periodic Golay pairs are a generalization of ordinary Golay pairs. They can be used to
construct Hadamard matrices. A positive integer v is a (periodic) Golay number if there exists …

On minors of maximal determinant matrices
RP Brent, JH Osborn - arxiv preprint arxiv:1208.3819, 2012 - arxiv.org
By an old result of Cohn (1965), a Hadamard matrix of order n has no proper Hadamard
submatrices of order m> n/2. We generalise this result to maximal determinant submatrices …

D-optimal matrices of orders 118, 138, 150, 154 and 174
D Ž.-Doković, IS Kotsireas - Algebraic Design Theory and Hadamard …, 2015 - Springer
We construct supplementary difference sets (SDSs) with parameters (59; 28, 22; 21),(69; 31,
27; 24),(75; 36, 29; 28),(77; 34, 31; 27) and (87; 38, 36; 31). These SDSs give D-optimal …

A feasibility approach for constructing combinatorial designs of circulant type
In this work, we propose an optimization approach for constructing various classes of
circulant combinatorial designs that can be defined in terms of autocorrelation. The problem …
