The Deficiency of Costas Arrays

IEEE Transactions on Information Theory, 2014
A Costas array is a permutation array in which the vectors joining pairs of 1s are all distinct. The toroidal vectors of a permutation array are the vectors occurring when the array is written on a torus, and the deficiency of a permutation array of order n is the number of toroidal vectors, out of the (n 1) 2 possible, which are missing from the ...

Protein Requirements of Costa's Hummingbirds Calypte costae

Physiological Zoology, 1991
Captive Costa's hummingbirds (Calypte costae) were fed liquid purified diets containing 0%, 0.75%, 1.5%, or 3.0% protein (dry-matter basis). The birds were weighed and excreta samples were collected at days 5 and 10 of 10-d experimental periods. Body-mass maintenance data revealed that the hummingbirds require about 4.5 mg N/d, or 1.5% protein in their

Costas permutations in the continuum

2008 42nd Annual Conference on Information Sciences and Systems, 2008
We extend the definition of the Costas property to functions in the continuum, namely on intervals of the reals or the rationals, and argue that such functions can be used in the same applications as discrete Costas arrays. We construct Costas bijections in the real continuum within the class of piecewise continuously differentiable functions; over the

Costa

Urbanistica Informazioni
La costa italiana è un territorio dinamico che cambia continuamente. L'ISPRA mappa e monitora le coste, analizzando gli elementi naturali e antropici che influenzano la morfodinamica costiera. La gestione integrata delle zone costiere considera la fragilità degli ecosistemi e la diversità delle attività umane.
