Crossing rate and distance in upland rice [PDF]

open access: yesBragantia, 2005
Rice (Oryza sativa L.) is an autogamous species that shows natural crossing rates of up to 3%, where the variations are influenced by genotypes and environments. The present work aimed to evaluate the rates and distances of natural crossing between the upland rice cultivars Guarani and IAC 201.

Modelling of N21P emission rates in aurora using various cross sections for excitation [PDF]

open access: yesAnnales Geophysicae, 2009
Measurements of N21P auroral emissions from the (4,1) and (5,2) bands have been made at high temporal and spatial resolution in the region of the magnetic zenith. The instrument used was the auroral imager ASK, situated at Ramfjordmoen, Norway (69.6 N,

Bounds and Prices of Currency Cross-Rate Options [PDF]

open access: yesSSRN Electronic Journal, 2007
Abstract This paper derives the pricing bounds of a currency cross-rate option using the option prices of two related dollar rates via a copula theory and presents the analytical properties of the bounds under the Gaussian framework. Our option pricing bounds are useful, because (1) they are general in the sense that they do not rely on the ...

Multilevel crossing rates for automated signal classification [PDF]

open access: yesICASSP '78. IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005
An investigation was made of multilevel crossing rates as a means of time series analysis of random signals. Pattern recognition techniques based on the Mahalanobis distance were implemented as a means of evaluating the discriminating power of level crossings.
