Local Sample Path Properties of Gaussian Fields

open access: yesThe Annals of Probability, 1979
A zero-one law is derived for a class of Gaussian fields $\{X(t) : t \in R^d\}$ including the generalized multiparameter Brownian motion. Under very general conditions, the joint distribution of the suprema of several Gaussian processes defined over compact metric spaces is shown to be absolutely continuous with a bounded density. Sufficient conditions

Some singular sample path properties of a multiparameter fractional Brownian motion [PDF]

open access: yes, 2016
We prove a Chung-type law of the iterated logarithm for a multiparameter extension of the fractional Brownian motion which is not increment stationary.

Marshall-Olkin Generalized Asymmetric Laplace distributions and processes

open access: yesStatistica, 2013
The Marshall-Olkin Generalised Asymmetric Laplace distribution is introduced and studied. An approximation is made and various properties including self decomposability, geometric infinite divisibility, limit properties etc.are established.

Tracy-Widom distribution, Airy2 process and its sample path properties [PDF]

open access: yesApplied Mathematics-A Journal of Chinese Universities, 2021
AbstractTracy-Widom distribution was first discovered in the study of largest eigenvalues of high dimensional Gaussian unitary ensembles (GUE), and since then it has appeared in a number of apparently distinct research fields. It is believed that Tracy-Widom distribution have a universal feature like classic normal distribution. Airy2process is defined

Passive element enriched photoacoustic computed tomography (PER PACT) for simultaneous imaging of acoustic propagation properties and light absorption\ud [PDF]

open access: yes, 2011
We present a ‘hybrid’ imaging approach which can image both light absorption properties and acoustic transmission properties of an object in a two-dimensional slice using a computed tomography (CT) photoacoustic imager.

Sample path properties of permanental processes

open access: yesElectronic Journal of Probability, 2018
Let $X_ =\{X_ (t),t\in T\}$, $ >0$, be an $ $-permanental process with kernel $u(s,t)$. We show that $X^{1/2}_ $ is a subgaussian process with respect to the metric $ (s,t)= (u(s,s)+u(t,t)-2(u(s,t)u(t,s))^{1/2})^{1/2}$. This allows us to use the vast literature on sample path properties of subgaussian processes to extend these properties to $

A detailed investigation on highly dense CuZr bulk metallic glasses for shielding purposes

open access: yesOpen Chemistry, 2022
Gamma-ray shielding properties of eight different metallic glasses based on CuxZr100-x: x = 35 (Cu35Zr65) − 70 (Cu70Zr30) were determined using Monte Carlo simulations and Phy-X/PSD software.

Stochastic Representation and Monte Carlo Simulation for Multiterm Time-Fractional Diffusion Equation

open access: yesAdvances in Mathematical Physics, 2020
In this paper, we mainly study the solution and properties of the multiterm time-fractional diffusion equation. First, we obtained the stochastic representation for this equation, which turns to be a subordinated process.

Energy-Efficient Local Path Planning of a Self-Guided Vehicle by Considering the Load Position

open access: yesIEEE Access, 2022
The local path planning, as one of the navigation stages, plays a significant role in the energy consumption of Self-Guided Vehicles (SGV). Since SGV must operate for several hours on a single battery charge to transport loads, its energy consumption is ...
