Dynamic daylight simulation variability in clear sky condition according to selected weather file: satellite data and land-based station data
(Sage Publications Ltd, 2015-12)
While the use of satellite weather files is a possibility in regions without terrestrial stations, it is necessary to consider their impact on daylight simulations. This paper aims to verify the variability of dynamic ...
Regolith production and chemical weathering of granitic rocks in central Chile
(Elsevier, 2016)
We have evaluated the long-term chemical and physical weathering mass balance of an anomalously thick saprolite profile (>30 in thickness) developed in granitic rocks near Curacavi, Coastal Range of central Chile. The ...

Optimal Static Hedging of Energy Price and Volume Risk: Closed-Form Results
(Universidad EAFITEscuela de Economía y Finanzas, 2012-12-15)
As an extension of the VaR-constrained hedging, we propose a closed-form solution to the problem of optimizing portfolios, based on price and weather. For electric power companies, price and quantity are volatile, and in ...
