Many flood events involving water and sediments have been characterized using classic hydraulics principles, assuming the existence of critical flow and many other simplifications. In this paper, hyperconcentrated flow ...
[ES] En la presente investigación se estudiarán diversos post procesadores estadísticos, aplicados a los caudales mensuales producto de modelos hidrologicos con el objeto de cuantificar la incertidumbre predictiva y mejorar ...
Safety related systems performance optimization is classically based on quantifying the effects that testing and maintenance activities have on reliability and cost (RC). However, RC quantification is often incomplete in ...
The gas-cooler heat exchanger is a characteristic device of the refrigeration plants that use CO2 as the working fluid in transcritical conditions. The proper gas-cooler sizing, allows getting the maximum effectiveness in ...

[EN] A model-based inverse problem strategy is proposed for damage characterization, starting from the electromechanical response measurement as input data, and incorporating a numerical model that simulates the piezoelectric ...
[EN] This study introduces a method to quantify the conditional predictive uncertainty in hydrological post-processing contexts when it is cumbersome to calculate the likelihood (intractable likelihood). Sometimes, it can ...
[EN] The Penman-Monteith equation for reference evapotranspiration (ET o) estimation cannot be applied in many situations, because climatic records are totally or partially not available or reliable. In these cases, empirical ...

The current work focuses on the study of the influence of pressure and temperature on three important thermodynamic properties: speed of sound, compressibility and density of common diesel fuels. The sample fuels studied ...
The Monte Carlo (MC) method can be applied to simulate brachytherapy treatment planning. The MCNP5 code gives, together with results, a statistical uncertainty associated with them. However, the latter is not the only ...

The objectives of this paper are the application of uncertainty and sensitivity analysis methods in
atmospheric dispersion modeling to study the prediction of the dispersion of pollutants in the
atmosphere. The Gaussian ...
