Se analiza rigurosamente la difracción de una onda plana electromagnética no-uniforme, en el borde de un semiplanoperfectamente conductor inmerso en un medio quiral (bi-anisotrópico). La expansión asintótica de la s...

Nowadays, in many fields of science it is necessary to carry out miscellaneous analyses using classical statistical methods, which usually have correct assumptions. These assumptions in the research realities cannot alwa...

We consider the problem of the estimation of the mean squared error (MSE) of some domain mean predictor for Fay‑Herriot model. In the simulation study we analyze properties of eight MSE estimators including estimators ...

Power-supply bootstrapping is a technique based on applying a DC-shifted copy of the input signal to the supply terminals of an operational amplifier (OA). It is usually applied configuring the OA as a unity-gain buffer,...

Background: In calibration, analytical figures of merit (AFOMs) are statistical parameters of great importance for method validation. In recent decades, relevant contributions have been made to estimate AFOMs in many cal...
