Transition to complete synchronization in phase-coupled oscillators with nearest neighbor coupling
(American Institute of Physics (AIP), 2009-03-01)
We investigate synchronization in a Kuramoto-like model with nearest neighbor coupling. Upon analyzing the behavior of individual oscillators at the onset of complete synchronization, we show that the time interval between ...
Determination of the critical coupling for oscillators in a ring
(American Institute of Physics (AIP), 2009-09-01)
We study a model of coupled oscillators with bidirectional first nearest neighbors coupling with periodic boundary conditions. We show that a stable phase-locked solution is decided by the oscillators at the borders between ...
Oviposition pattern and within-season spatial and temporal variation of pre-dispersal seed predation in a population of Mimosa bimucronata trees
(Springer, 2011-09-01)
Spatial and temporal variation of pre-dispersal seed predation was investigated in a population of Mimosa bimucronata trees located in the south-east region of Brazil. Three main hypotheses were addressed: (1) that the ...
Seed germination and seedling emergence of the invasive exotic species, Clausena excavata
(Instituto Internacional de Ecologia, 2010-11-01)
Este estudo teve como objetivos avaliar os efeitos da luz e da temperatura na germinação de sementes e o efeito da luz na emergência das plântulas de Clausena excavata, uma espécie exótica invasora. O experimento de ...
Comportamento sócio-sexual e de manutenção de touros nelore durante a estação de monta
(2010-08-03)
Changes in the bull: cow proportion in natural breeding have been proposed, but there are not evaluations about the effect of these changes in the behaviour of Nellore bulls. The objective of this study was to test the ...
Solution approaches for the soft drink integrated production lot sizing and scheduling problem
(Elsevier B.V., 2009-07-16)
In this paper we present a mixed integer programming model that integrates production lot sizing and scheduling decisions of beverage plants with sequence-dependent setup costs and times. The model considers that the ...
On the control of vibrations using synchrophasing
(2013-09-30)
This paper describes the application of a technique, known as synchrophasing, to the control of machinery vibration. It is applicable to machinery installations, in which several synchronous machines, such as those driven ...
Effect of superstimulatory treatments on the expression of genes related to ovulatory capacity, oocyte competence and embryo development in cattle.
(2012-12-01)
Multiple ovulation (superovulation) and embryo transfer has been used extensively in cattle. In the past decade, superstimulatory treatment protocols that synchronise follicle growth and ovulation, allowing for improved ...
