A method of signal estimation error reduction in a priori indeterminacy

2015 23rd Telecommunications Forum Telfor (TELFOR), 2015
In the paper presented results of studying the convergence of desired signal estimation error using only one measurement of noised signal and original method of estimation. The estimation of signal without a priori information about signal function compare with estimation got by RMSE method.

A Priori Truncation Error Estimates for Stieltjes Fractions

1981
Stieltjes fractions are here studied in the form K(a n z/1), a n > 0, n ≥ 1. They provide expansions for many useful functions and have integral representations $$ \int\limits_0^\infty {\frac{{zd\psi (t)}}{{1 + zt}}} $$ .

Error Estimations in Linear Inverse Problems With a Priori Information

Volume 2: 31st Computers and Information in Engineering Conference, Parts A and B, 2011
We consider an inverse problem for an operator equation Az = u. The exact operator A and the exact right-hand side u are unknown. Only their upper and lower estimations are available. We provide techniques of calculating upper and lower estimations for the exact solution belonging to a compact set in this case, as well as a posteriori error estimations.

A priori error estimates for the Arbitrary Lagrangian Eulerian formulation with finite elements

Journal of Numerical Mathematics, 2001
The approximation by finite elements of a time-dependent advection-diffusion problem in a moving two-dimensional domain is considered. The author assumes that the motion of the boundary of the domain is given. This problem is discretized by linear finite elements in space and a modification of the implicit Euler scheme, based on the mid-point rule, in ...

A Priori Error Estimates for Nonlinear Scalar Conservation Laws

1999
In this note, we review the recent work of the authors on a priori error estimates for nonlinear scalar conservation laws. A priori error estimates are important because they shed light into the nature of the corresponding numerical scheme. In this note, we show how to use our a priori error estimation technique to study multidimensional monotone ...

A priori local error estimation with adaptive time-stepping

Communications in Numerical Methods in Engineering, 1999
Summary: We present an a priori local error estimator for one-step implicit time-stepping schemes of Padé type; such algorithms are widely used in structural dynamics. The proper time step \(h\) to be done can be calculated by matching a given local accuracy. The numerical process to evaluate \(h\) is straightforward and explicit.
