An Even Order Search Problem

1987
How might simple real zeros of real valued continuous k-th derivatives g(k) be efficiently estimated, by using only values of g and points in dom(g)? A standard approach to these questions entails successively ehoosing a (prescribed) total of n>k points to be the abscissae for sequences of k-th divided differences,whose signs are then used to locate ...

Even-Order Subharmonics in the Peripheral Auditory System

The Journal of the Acoustical Society of America, 1966
It was observed that the conventional one-half frequency undertones primarily occur above 2500–3000 Hz. In a series of experiments, these subharmonics were monitored in the sound field in front of the tympanic membrane, while first the cochlea and then the stapes were removed. It was found that the presence of the cochlea or the stapes is not necessary

Williamson matrices of even order

1974
Recent advances in the construction of Hadamard matrices have depended on the existence of Baumert-Hall arrays and Williamson-type matrices. These latter are four (1,-1) matrices A,B,C,D, of order m, which pairwise satisfy (i) MNT = NMT, M,N e {A,B,C,D}, and (ii) AAT+BBT+CCT+DDT = 4mIm, where I is the identity matrix.

Symplectic translation planes of even order

2006
Symplectic translation planes of even order are investigated. Such planes are characterised by the existence of completely regular line--ovals, and these line--ovals give rise to symmetric designs isomorphic to certain designs investigated by Kantor. The use of these designs allows us to describe the collineation group fixing a completely regular line--

Graphs, codes and Buekenhout ovals of even order

1990
The conjecture that every Buekenhout oval (or B-oval) was projective had been unsolved for long time; in 1977, N. Krier disproved it by constructing an example of a non-projective B-oval with the point set of integers. By observing the strong connection between the finite \(B\)-ovals of even order \(n\) and the complete graphs \(K_{n+2}\) the author ...
