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...

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...

Purpose: The purpose of this paper is to evaluate the capability of the hidden Markov model using Googling investors’ sentiments to predict the dynamics of Islamic indexes’ returns in the Middle East and North Africa (MENA) financial markets from 2004 to 2018. Design/methodology/approach:...

Purpose: The purpose of this paper is to analyze how monetary fundamentals affect exchange rate movements. Design/methodology/approach: To develop this paper, a Bayesian Network modeling is applied to explore the causal interactions between monetary fundamentals and exchange rate fluctuations....

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.

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...
