In this study, we capture the impact of changing temperature and rainfall patterns on estimated consumption macro-and micronutrients among households in Malawi. We apply a fixed-effects model to household panel data collected between 2010 2017, which contains detailed information food consumption, combined with over past 30 years. turn, aim identify weather shocks nutrition security. find decre...

We present a generalisation of the double long memory ARFIMA-FIGARCH model introducing time-varying memory coefficients both in the mean and in the variance. The model satisfies the empirical evidence of changing memory observed in average temperature series and can provide useful improvements in the forecasting, simulation and pricing issues related to weather derivatives. We provide an applic...

In this paper, an outdoor multi-camera video surveillance system operating under changing weather conditions is presented. A new confidence measure, Appearance Ratio (AR), is defined to automatically evaluate the sensors’ performance for each time instant. By comparing their ARs, the system can select the most appropriate cameras to perform specific tasks. When redundant measurements are availa...
