Lattice constellations and codes from quadratic number fields
(2001-05-01)
We propose new classes of linear codes over integer rings of quadratic extensions of Q, the field of rational numbers. The codes are considered with respect to a Mannheim metric, which is a Manhattan metric modulo a ...

(2021-02-24)
Este trabalho de conclusão de curso apresenta uma construção de códigos matriciais MDS (Maximum Distance Separable) com o objetivo de abordar uma estratégia de correção de erros em rajada nestes códigos. Para obter um ...
THE REDDENING-FREE DECLINE RATE VERSUS LUMINOSITY RELATIONSHIP FOR TYPE Ia SUPERNOVAE
(1999-10)
We develop a method for estimating the host galaxy dust extinction for type Ia supernovae based on
an observational coincidence Ðrst noted by Lira, who found that the B[V evolution during the period
from 30 to 90 days ...
Quantification of the environmental effect on citrus canker intensity at increasing distances from a natural windbreak in northeastern Argentina
(Springer, 2014-07-15)
Citrus canker, caused by the bacterium Xanthomonas citri pv. citri (Xcc), is an endemic quarantine
disease in northeastern Argentina. The objective of this study was to quantify the effect of weather variables on mid-season ...
