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

Non intrusive polynomial chaos-based stochastic macromodeling of multiport systems [PDF]
, 2014 We present a novel technique to efficiently perform the variability analysis of electromagnetic systems. The proposed method calculates a Polynomial Chaos-based macromodel of the system transfer function that includes its statistical properties.

On Solving Parametric Polynomial Systems [PDF]
Mathematics in Computer Science, 2012 This work intends to cover similar ground and extend the paper [\textit{D. Lazard} and \textit{F. Rouillier}, J. Symb. Comput. 42, No. 6, 636--667 (2007; Zbl 1156.14044)]. Unfortunately the present paper is of questionable quality. The English is at times hard to follow and the paper lacks mathematical substance.

Cubic Spline Solution of linear fourteenth order boundary value problems
Ceylon Journal of Science, 2018 As higher order differential equations have constantly been tiresome and problematic to resolve for the mathematicians and engineers so diverse numerical procedures were conceded out to acquire numerical estimates to such problems.

Domain-of-Attraction Estimation for Uncertain Non-polynomial Systems
, 2013 In this paper, we consider the problem of computing estimates of the domain-of-attraction for non-polynomial systems. A polynomial approximation technique, based on multivariate polynomial interpolation and error analysis for remaining functions, is ...

Automorphisms of algebras and Bochner`s property for discrete vector orthogonal polynomials [PDF]
, 2016 We construct new families of discrete vector orthogonal polynomials that have the property to be eigenfunctions of some difference operator. They are extensions of Charlier, Meixner and Kravchuk polynomial systems.

Subsystems of the polynomial system [PDF]
Pacific Journal of Mathematics, 1983 This paper deals with the classification of subsystems of a polynomial system. A system is defined as a pair of complex vector spaces (V,W) for which there exists a \({\mathbb{C}}\)-bilinear map from \({\mathbb{C}}^ 2\times V\) to W, where \({\mathbb{C}}\) is the field of complex numbers.

Zero Distribution of System with Unknown Random Variables Case Study: Avoiding Collision Path
MATEC Web of Conferences, 2014 This paper presents the stochastic analysis of finding the feasible trajectories of robotics arm motion at obstacle surrounding. Unknown variables are coefficients of polynomials joint angle so that the collision-free motion is achieved.
