Logarithmic Gradient Transformation and Chaos Expansion of Ito Processes [PDF]

open access: yes, 2018
Since the seminal work of Wiener, the chaos expansion has evolved to a powerful methodology for studying a broad range of stochastic differential equations. Yet its complexity for systems subject to the white noise remains significant.

Generalized Gamma Convolutions, Dirichlet means, Thorin measures, with explicit examples [PDF]

open access: yes, 2008
In Section 1, we present a number of classical results concerning the Generalized Gamma Convolution (:GGC) variables, their Wiener-Gamma representations, and relation with the Dirichlet processes.To a GGC variable, one may associate a unique Thorin ...

Quasi-invariant measures on the path space of a diffusion [PDF]

open access: yes, 2006
The author has previously constructed a class of admissible vector fields on the path space of an elliptic diffusion process $x$ taking values in a closed compact manifold.

Evaluation the Distribution of Effective Factors on Habitat Diversity in Kermanshah Protected Areas

open access: yesجغرافیا و پایداری محیط, 2020
Destruction and habitat fragmentation are considered as the most challenging issues of biodiversity and establishment of protected areas is one of preventive methods to reduce biodiversity. Therefore, there are different criteria to choose it. Kermanshah

A wavelet analysis of the Rosenblatt process: chaos expansion and estimation of the self-similarity parameter [PDF]

open access: yes, 2010
By using chaos expansion into multiple stochastic integrals, we make a wavelet analysis of two self-similar stochastic processes: the fractional Brownian motion and the Rosenblatt process.

The impact of the diagonals of polynomial forms on limit theorems with long memory [PDF]

open access: yes, 2016
We start with an i.i.d. sequence and consider the product of two polynomial-forms moving averages based on that sequence. The coefficients of the polynomial forms are asymptotically slowly decaying homogeneous functions so that these processes have long ...

Stein's method meets Malliavin calculus: a short survey with new estimates [PDF]

open access: yes, 2009
We provide an overview of some recent techniques involving the Malliavin calculus of variations and the so-called ``Stein's method'' for the Gaussian approximations of probability distributions.

Introduction to Random Signals and Noise [PDF]

open access: yes, 2006
Random signals and noise are present in many engineering systems and networks. Signal processing techniques allow engineers to distinguish between useful signals in audio, video or communication equipment, and interference, which disturbs the desired ...

Structure of the third moment of the generalized Rosenblatt distribution [PDF]

open access: yes, 2014
The Rosenblatt distribution appears as limit in non-central limit theorems. The generalized Rosenblatt distribution is obtained by allowing different power exponents in the kernel that defines the usual Rosenblatt distribution.

Noncrop features and heterogeneity mediate overwintering bird diversity in agricultural landscapes of southwest China

open access: yesEcology and Evolution, 2020
Farmland birds are of conservation concerns around the world. In China, conservation management has focused primarily on natural habitats, whereas little attention has been given to agricultural landscapes.
