โœฆ Synopsis

In this paper, a comparison is made between two methods which are used for interpolation/extrapolation of frequency domain responses. The first method is the direct Consider a system function H(s). The objective is method based on the principle of a model-based parameter to approximate H(s) by a ratio of two polynomials estimation and the second uses the properties of discrete A(s) and B(s) so that H(s) can be represented by Hilbert transforms based on the principle of causality.

## Abstract The scattering from finite frequency selective surfaces (FSSs) characterized by planar interfaces is analyzed, resorting to two POโ€based hybrid techniques. The hybrid techniques, validated with a fullโ€wave numerical technique, are easy to implement, fast, and already quite accurate for

## Abstract In many cases, boundary integral equations contain a domain integral. This can be evaluated by discretization of the domain into domain elements. Historically, this was seen as going against the spirit of boundary element methods, and several methods were developed to avoid this discret

The goal when developing an in vitro-in vivo correlation (IVIVC) model is the ability to accurately predict the in vivo plasma concentration profile of a drug formulation using only its in vitro dissolution data. The prediction accuracy of any model depends on the reliability of the method used to d
