Calculation of the statistical properties in intermittency using the natural invariant density
(Multidisciplinary Digital Publishing Institute, 2021-06)
We use the natural invariant density of the map and the Perron–Frobenius operator to analytically evaluate the statistical properties for chaotic intermittency. This study can be understood as an improvement of the previous ...
Nonparametric estimation of a surrogate density function in infinite-dimensional spaces
(Taylor & Francis Ltd, 2012-06)
A density function is generally not well defined in functional data context, but we can define a surrogate of a probability density, also called pseudo-density, when the small ball probability can be approximated by the ...
Discontinuous reinjection probability density functions in type v intermittency
(American Society of Mechanical Engineers (ASME), 2018-12)
This paper reports theoretical and numerical results about the reinjection process in type V intermittency. The M function methodology is applied to a simple mathematical model to evaluate the reinjection process through ...
Nonuniform reinjection probability density function in type V intermittency
(Springer, 2018-04)
In this paper, type V intermittency is studied using the M function methodology developed in the last years. This methodology is applied on two different maps to evaluate the reinjection probability density function (RPD), ...
Functional integral approach to the transfer function of a stochastic scattering channel
(Taylor & Francis Ltd, 2020-10)
We apply the formalism of functional integration to the calculation of the transfer function of a stochastic scattering channel formed by stationary, non-interacting point scatterers. The channel is described through a ...
LDPE Production in Tubular Reactors: Comprehensive Model for the Prediction of the Joint Molecular Weight-Short (Long) Chain Branching Distributions
(American Chemical Society, 2019-03)
Good control on molecular properties, and as a consequence on end-use properties, is very important for low-density polyethylene (LDPE) manufacturers. However, the connection between the architecture of polymer chains and ...
Where are the particles when the box is hot?
(IOP Publishing, 2019-09)
We consider the known problem of a particle in a one-dimensional box, i.e. in an infinite potential well. Specifically, we evaluate the probability density for finding a particle in a certain position when the system is ...
Exact factorization-based density functional theory of electron-phonon systems
(American Physical Society, 2019-04)
Density functional theory is generalized to incorporate electron-phonon coupling. A Kohn-Sham equation yielding the electronic density nU(r), a conditional probability density depending parametrically on the phonon normal ...
Reinjection Probability Density for Type-III Intermittency with Noise and Lower Boundary of Reinjection
(American Society of Mechanical Engineers, 2017-05)
In this paper, we extend a methodology developed recently to study type-III intermittency considering different values of the noise intensity and the lower boundary of reinjection (LBR). We obtain accurate analytic expressions ...
Seed dispersal effectiveness by frugivorous birds: Identifying functional equivalent species in bird assemblages
(Science Reviews 2000 Ltd, 2019-08)
Seed dispersal by birds is a pivotal ecosystem function worldwide; yet, the rapid and ongoing global biodiversity loss poses a major threat to this essential ecosystem service. Seed dispersal effectiveness (SDE) is a key ...
