We introduce here a new method to obtain the Taylor series expansion of the objective function, called the Finite Element Method over a Polynomial Algebra (FEMPA), that keeps

We have carried out numerical simulations to compare the new method with the classical finite element approximation based on uncut mesh and with the same approach without

On the basis of the LAN, an efficient test of linearity based on Neyman-Pearson-type statistics was obtained in a class of nonlinear time series models contiguous to a

Interpolation for the thermal layerwise beam element As seen in the mechanical part (Section 2.3), a finite element corresponding to the temperature field is developed to analyze

To achieve this task, a model reduction technique is proposed which involves partitioning a whole periodic structure into one central structure surrounded by two unperturbed

The characteristics for the five most repeated prokaryote genomes are pre- sented in Table 1. These short genome sequences have been extensively studied and are well known
