The effects of electromagnetic fields on fish

The objective of this paper is to survey the results of studies on the biological effects of electromagnetic fields on fish. First, the basic concepts of electromagnetism and electromagnetic spectrum and the importance of studying it in the case of fish are discussed. Then a summary of the results obtained on the effects of extremely low frequency electromagnetic fields (ELF-EMFs) and radiofreq...

Numerical Calibration and De-embedding Techniques for CAD and Equivalent Circuit Models of Electromagnetic Structures

-The numerical calibration and de-embedding techniques used in the planar electromagnetic (EM) simulation are reviewed. These techniques are used to eliminate the port discontinuities brought by the current/voltage exciting source. Therefore, accurate equivalent circuit model of the planar discontinuities can be extracted. Index Terms – calibration technique, equivalent circuit model, planar di...

Estimation of Single-Index Models Based on Boosting Techniques

In single-index models the link or response function is not considered as fixed. The data determine the form of the unknown link function. In order to obtain a flexible form of the link function we specify the link function as an expansion in basis function and propose to estimate parameters as well as the link function by weak learners within a boosting framework. It is shown that the method i...

Estimation in ARMA models based on signed ranks

In this paper we develop an asymptotic theory for estimation based on signed ranks in the ARMA model when the innovation density is symmetrical. We provide two classes of estimators and we establish their asymptotic normality with the help of the asymptotic properties for serial signed rank statistics. Finally, we compare our procedure to the one of least-squares, and we illustrate the performa...
