Interest and exchange rate risk and stock returns : a multivariate GARCH-M modelling approach
Published 2008“…The econometric framework is a four-variate GARCH-in-mean model, which incorporates long-and short-term interest rates in turn. We find in most cases a positive effect of stock market returns on mean returns in each sector; by contrast, interest rates and exchange rates have a significant effect only in a few cases, respectively negative and without a clear sign pattern. …”

Meeting the challenges of chemical and biological weapons: strengthening the chemical and biological disarmament and non-proliferation regimes
Published 2022“…During this century despite the agreement of some positive measures to strengthen these Disarmament and Non-Proliferation Regimes, there is little doubt that both are facing considerable difficulties at present. However, there is a long and diverse tradition of civil society efforts to help strengthen these regimes and there is some hope that, following the dangers from biological agents exposed in the pandemic, States Parties will be able to find ways to improve the protection afforded by the two Conventions. …”

Neutral point inverter controller using H infinity techniques
Published 2014“…This can be achieved by using a neutral-point circuit that consists of a conventional neutral leg and a split dc link. In this project, a H infinity (H∞ ) current controller is proposed to force the current flowing through the split dc link to be nearly zero so that the neutral-point current is stable, and then, a current control loop is added to eliminate the imbalance of the current so that the neutral-point current is balanced with respect to the dc terminals. …”
