Crecimiento de terneras F1 y F2 Kiwi Cross x Holstein

Emulación del Crecimiento de Hongos Comestibles y Medicinales utilizando un Algoritmo Evolutivo con un Operador Genético de tipo Cilíndrico

In this article a computational model for the interpolation and exploration of Complex Response Surfaces is described and analyzed. This computational model consists of two stages: an initial stage in which a group of points is interpolated by means of the coalition of a series of characteristic concepts of vector geometry, the numeric methods and the evolutionary computation to construct the r...

On iteration invariants for (F1,F2)-sensitivity and weakly (F1,F2)-sensitivity of non-autonomous discrete systems

In this paper, we let (X, f1,∞) be a non-autonomous discrete system on a compact metric space X. For a positive k, the properties P̂ (k) and Q̂(k) of Furstenberg families are introduced for any integer k > 0. Based on the two properties, we prove that (F1,F2)sensitivity and weakly (F1,F2)-sensitivity are invariant under iterations. MR(2000) Subject Classification: 54H20, 54B20, 37B99, 37D45.

Production characters of straightbred, F1 and F2 cows: birth and weaning characters of terminal-cross calves.

Records of 2,449 births and 2,120 weanings of terminal-cross calves were used to characterize maternal productivity of first- and second-generation cows from a diallel of Angus, Brahman, Hereford, Holstein and Jersey when mated to third-breed sires. Third- and later-parity cows were randomly assigned after each parturition to Charolais and Red Poll bulls in multiple-sire pastures. Calves were w...

Heterosis and heritability for yield and yield components in F1 and F2 generations of a bean cross

Cancellation level and phase of the (f2-f1) distortion product.

The cancellation level and phase were measured for the (f2-f1) distortion product in six normal-hearing ears as a function of input level (L1,L2) and the frequency separation of the two input signals (f1,f2, where f2 greater than f1). The effects of input level were examined for L1 and L2, varied together (L1 = L2) and separately. Typically, f1 was 1500 Hz while f2/f1 was either 1.16, 1.32, 1.4...
