A conceptual numerical model to simulate hydraulic head in aquifers that are hydraulically connected to surface water bodies

Pulido Velázquez, David; Sahuquillo Herráiz, Andrés; Andreu Álvarez, Joaquín (Wiley: 12 months, 2011-07)

In this paper, we present a conceptual-numerical model that can be deduced from a calibrated finite difference groundwater-flow model, which provides a parsimonious approach to simulate and analyze hydraulic heads and ...
Distributed sediment yield modelling: Importance of initial sediment conditions

Bussi, Gianbattista; Francés García, Félix Ramón; Montoya, JJ; Julien Y, Pierre (Elsevier, 2014-08)

The importance of initial sediment conditions on model calibration and validation is analysed. A sediment model was calibrated and validated under three different initial sediment conditions: (0) no sediment availability, ...
Noninvasive monitoring of polymer curing reactions by dielectrometry

García Baños, Beatriz; Canós Marín, Antoni Josep; Peñaranda Foix, Felipe Laureano; Catalá Civera, José Manuel (Institute of Electrical and Electronics Engineers (IEEE), 2011-01)

A microwave sensor system for the noninvasive monitoring of the curing process of a thermoset material placed inside a metallic mold is described. The microwave sensor is designed as an open-ended coaxial resonator with a ...
Random Hermite differential equations: Mean square power series solutions and statistical properties

Calbo Sanjuán, Gema; Cortés López, Juan Carlos; Jódar Sánchez, Lucas Antonio (Elsevier, 2011-12-01)

This paper deals with the construction of random power series solution of second order linear differential equations of Hermite containing uncertainty through its coefficients and initial conditions. Under appropriate ...
Solving Riccati time-dependent models with random quadratic coefficient

Cortés López, Juan Carlos; Jódar Sánchez, Lucas Antonio; Company Rossi, Rafael; Villafuerte Altuzar, Laura (Elsevier, 2011-12)

This paper deals with the construction of approximate solutions of a random logistic differential equation whose nonlinear coefficient is assumed to be an analytic stochastic process and the initial condition is a random ...
Solving the random Legendre differential equation: Mean square power series solution and its statistical functions

Calbo Sanjuán, Gema; Cortés López, Juan Carlos; Jódar Sánchez, Lucas Antonio; Villafuerte Altuzar, Laura (Elsevier, 2011-05)

In this paper we construct, by means of random power series, the solution of second order linear differential equations of Legendre-type containing uncertainty through its coefficients and initial conditions. By assuming ...
Una nueva aproximación para la evaluación del golpe de ariete incluyendo la condición inicial de presurización de la instalación y del fluido

Kaless, G. (Universitat Politècnica de València, 2016-04-29)

[EN] The water hammer phenomenon is well known since the 19th century, while its mathematical formulation, by means of differential equations, is due to works of researchers such us Allievi (1903) and others from the ...
