This paper is interested in the control of a wind energy conversion system (WECS) based on the doubly fed induction generator (DFIG) under grid fault conditions. A single line to ground fault and a double line to ground fault are tested during the hyper-synchronous operation of the DFIG wind...

Let F={P[theta];[theta][set membership, variant][Theta]} be a natural exponential family on and let H be an exposed face of the closed convex hull of the F support. The aim of this paper is to study the asymptotic behavior of the law P[theta]+[lambda]u as [lambda] increases to +[infinity], for...

In this paper, we show that the multinomial exponential families in a d-dimensional linear space are characterized by the determinant of their covariance matrix, named generalized variance.

We study the k-dimensional gamma-Gaussian model (k1) composed by distributions of random vector X=(X1,X2,…,Xk)⊤, where X1 is a univariate gamma distributed, and (X2,…,Xk) given X1 are k−1 real independent Gaussian variables with variance X1. We first solve a particular Monge–Ampère...

This study investigates the relationship between inflation, inflation uncertainty and output in Tunisia using real and nominal data. GARCH-in-mean model with lagged variance equation is employed for the analysis. The result shows that inflation uncertainty has a positive and significant effect...

On the basis of SVAR models of monetary policy in Egypt for the period December 1976–May 2006, our paper explores a new empirical assessment for the interest rate channel in correcting trouble in the Egyptian economy by imposing contemporaneous and long run restrictions. It appears that after...

Monetary policy contributes to stabilize growth. Particularly in a reforming context for financial and economic activities, it is important to know how central bankers’ decisions through the short term interest rate of the money market are transmitted to the real variables: the GDP and the...
