Condition Monitoring (CM) of wind turbines can greatly reduce the maintenance costs for wind farms, especially for offshore wind farms. A new condition monitoring method for a wind turbine gearbox using temperature trend analysis is proposed. Autoassociative Kernel Regression (AAKR) is used to...

Economic studies have demonstrated, both empirically and theoretically, that higher levels of human development (HD) and economic freedom (EF) are associated with lower levels of perceived corruption. This study separately examines the impact of human development and economic freedom on...

En este trabajo se propone una extension de los modelos de valoracion factoriales. A diferencia del enfoque clasico donde el valor bursatil solo es considerado en la ultima fase del procedimiento de valoracion, la nueva propuesta lo incorpora con anterioridad al propio uso del analisis...

This paper studies the weak convergence of the sequential empirical process $\hat{K}_n$ of the estimated residuals in ARMA(p,q) models when the errors are independent and identically distributed. It is shown that, under some mild conditions, $\hat{K}_n$ converges weakly to a Kiefer process. The...
