Using water level and temperature time series to improve hydrogeological parameterization in a complex alluvial system

Acque Sotterranee, 2019
A new pumping station was designed in the northern high plain of the province of Padua (Veneto region, north-eastern Italy), aiming to reach an overall abstraction rate of about 2 m3/s, in order to relevantly contribute to the regional drinking water ...

Probability distribution of drawdowns in risky investments

, 1998
We study the risk criterion for investments based on the drawdown from the maximal value of the capital in the past. Depending on investor's risk attitude, thus his risk exposure, we find that the distribution of these drawdowns follows a general power ...

Erratum to: An approach to interpretation of step drawdown tests [PDF]

Hydrogeology Journal, 2011
The work used two approaches for fixing the boundary to fluid flow. In the first approach the boundary to fluid flow was assumed to be length from the well bottom to the pumping water level. The second approach was based on the assumption of the boundary length being the total length of the screen (See section Calculation of Reynold’s number on page ...

Hedge fund return predictability; To combine forecasts or combine information? [PDF]

, 2014
While the majority of the predictability literature has been devoted to the predictability of traditional asset classes, the literature on the predictability of hedge fund returns is quite scanty. We focus on assessing the out-of-sample predictability of
