First-order and higher-order approximations of observation impact

Meteorologische Zeitschrift, 2007
In studies by Errico (2007) and Gelaro et al. (2007), it was found that first order approximations of the reduction of forecast error by the analysis were systematically close to twice the correct value, while higher order approximations lead to relatively accurate estimations.

Interpolation for neural-network operators activated with a generalized logistic-type function

Journal of Inequalities and Applications
This paper defines a family of neural-network interpolation operators. The first derivative of generalized logistic-type functions is considered as a density function.

Second Order Filter Distribution Approximations for Financial Time Series with Extreme Outliers [PDF]

Particle Filters are now regularly used to obtain the filter distributions associated with state space financial time series. Most commonly used nowadays is the auxiliary particle filter method in conjunction with a first order Taylor expansion of the ...

First-order approximation of algorithmic theories

Theoretical Computer Science, 1986
Relations are investigated between an algorithmic theory and its first- order translation in which sorts of variables for natural numbers and objects for the coding of computations are added. In particular it is investigated what properties of the original algorithmic theory are preserved by the translation to a first-order language.

Numerical approximation of the 3rd order pseudo-parabolic equation using collocation technique

Boundary Value Problems
This study presents a novel numerical approach for approximating the solution of third-order pseudo-parabolic partial differential equations (PDEs), which exhibit both parabolic and hyperbolic characteristics.

Existence and approximation of solutions of second order nonlinear Neumann problems

Electronic Journal of Differential Equations, 2005
We study existence and approximation of solutions of some Neumann boundary-value problems in the presence of an upper solution $eta$ and a lower solution $alpha$ in the reversed order ( $alphageq eta$).
