Crosstalk statistics via collocation method [PDF]
A probabilistic model for the evaluation of transmission lines crosstalk is proposed. The geometrical parameters are assumed to be unknown and the exact solution is decomposed into two functions, one depending solely on the random parameters and the other on the frequency.

ISOGEOMETRIC COLLOCATION METHODS [PDF]
We initiate the study of collocation methods for NURBS-based isogeometric analysis. The idea is to connect the superior accuracy and smoothness of NURBS basis functions with the low computational cost of collocation. We develop a one-dimensional theoretical analysis, and perform numerical tests in one, two and three dimensions.

Reduced Collocation Methods: Reduced Basis Methods in the Collocation Framework [PDF]
In this paper, we present the first reduced basis method well-suited for the collocation framework. Two fundamentally different algorithms are presented: the so-called Least Squares Reduced Collocation Method (LSRCM) and Empirical Reduced Collocation Method (ERCM). This work provides a reduced basis strategy to practitioners who {prefer} a collocation,

Spectral collocation methods [PDF]
This review covers the theory and application of spectral collocation methods. Section 1 describes the fundamentals, and summarizes results pertaining to spectral approximations of functions. Some stability and convergence results are presented for simple elliptic, parabolic, and hyperbolic equations.

A fractional spline collocation method for the fractional order logistic equation [PDF]
We construct a collocation method based on the fractional B-splines to solve a nonlinear differential problem that involves fractional derivative, i.e. the fractional order logistic equation.

A point collocation approach to modelling large dissipative silencers [PDF]
A numerical matching technique known as point collocation is used to model mathematically large dissipative splitter silencers of a type commonly found in HVAC ducts. Transmission loss predictions obtained using point collocation are compared with exact

Stability of Chebyshev collocation methods
AbstractIn [1], a class of global collocation methods for the numerical solution of systems of nonlinear first-order ordinary differential equations was derived.The favorable comparison with other existing methods stimulated us to study them in depth.

On the asymptotic convergence of collocation methods [PDF]
We prove quasioptimal and optimal order estimates in various Sobolev norms for the approximation of linear strongly elliptic pseudodifferential equations in one independent variable by the method of nodal collocation by odd degree polynomial splines.
