Performance of Modal Signaling vs. medium dielectric variability [PDF]

open access: yes, 2012
This paper addresses the feasibility of the so-called Modal Signaling (MS) transmission scheme from a stochastic viewpoint. MS has been proposed for crosstalk mitigation over interconnects and is based on the encoding of signals onto fundamental ...

Polynomial chaos expansions for damped oscillators

open access: yes, 2015
Uncertainty quantification is the state-of-the-art framework dealing with uncertainties arising in all kind of real-life problems. One of the framework’s functions is to propagate uncertainties from the stochastic input factors to the output quantities of interest, hence the name uncertainty propagation.

Polynomial Chaos Expansion Approach to Interest Rate Models

open access: yesJournal of Probability and Statistics, 2015
The Polynomial Chaos Expansion (PCE) technique allows us to recover a finite second-order random variable exploiting suitable linear combinations of orthogonal polynomials which are functions of a given stochastic quantity ξ, hence acting as a kind of ...

Compressive sensing adaptation for polynomial chaos expansions

open access: yes, 2018
Basis adaptation in Homogeneous Chaos spaces rely on a suitable rotation of the underlying Gaussian germ. Several rotations have been proposed in the literature resulting in adaptations with different convergence properties.

An Efficient Polynomial Chaos Method for Stiffness Analysis of Air Spring Considering Uncertainties

open access: yesComplexity, 2021
Traditional methods for stiffness analysis of the air spring are based on deterministic assumption that the parameters are fixed. However, uncertainties have widely existed, and the mechanic property of the air spring is very sensitive to these ...

Time-Dependent Reliability-Based Design Optimization Utilizing Nonintrusive Polynomial Chaos

open access: yesJournal of Applied Mathematics, 2013
Time-dependent reliability-based design optimization (RBDO) has been acknowledged as an advance optimization methodology since it accounts for time-varying stochastic nature of systems. This paper proposes a time-dependent RBDO method considering both of

Polynomial chaos forward models in Bayesian inference to solve inverse problems [PDF]

open access: yes, 2011
In this paper we introduce polynomial chaos in the stochastic forward model used to solve the inverse problem through Bayesian inference. We validate our approach with three different methods that construct the stochastic forward model, to treat the TEAM

A New Uncertain Analysis Method for the Prediction of Acoustic Field with Random and Interval Parameters

open access: yesShock and Vibration, 2016
For the frequency response analysis of acoustic field with random and interval parameters, a nonintrusive uncertain analysis method named Polynomial Chaos Response Surface (PCRS) method is proposed.

A Class of Quadratic Polynomial Chaotic Maps and Their Fixed Points Analysis

open access: yesEntropy, 2019
When chaotic systems are used in different practical applications, such as chaotic secure communication and chaotic pseudorandom sequence generators, a large number of chaotic systems are strongly required.

Uncertainty through polynomial chaos in the EEG problem [PDF]

open access: yes, 2011
A sensitivity and correlation analysis of EEG sensors influenced by uncertain conductivity is conducted. We assume a three layer spherical head model with different and random layer conductivities. This randomness is modeled by Polynomial Chaos (PC).
