Pumping tests data interpretation is of major importance in groundwater engineering. It is traditionally performed in a subjective manner by means of standard type curves. In this paper, an automatic interpretation of time-drawdown data has been proposed based on two algorithms, the real-coded genetic algorithm and differential evolution. The proposed approaches combine metaheuristic algorithms with...
Fiber reinforced polymer (FRP) bars exhibit higher thermal properties in transverse direction with respect to concrete. This difference in transverse thermal properties between FRP and concrete may affect transverse thermal deformations and consequently cracking thermal loadings producing failure of concrete cover. This paper presents a numerical study to investigate the effect of thermal and mechanical...
Chaotic analysis of hydrological series revealed the presence of chaotic structures. As such, a Chaotic Neural Network model was proposed for daily rainfall-runoff. The approach is based on the combination of the series generated by the reconstruction of the phase space according to the method of Takens, in an artificial neural network. The results are very encouraging and open the prospects for other...
