A comparative study to the numerical approximation of random Airy differential equation

Cortés López, Juan Carlos; Jódar Sánchez, Lucas Antonio; Romero Bauset, José Vicente; Roselló Ferragud, María Dolores (Elsevier, 2011-11)

The aim of this paper is twofold. First, we deal with the extension to the random framework of the piecewise Fröbenius method to solve Airy differential equations. This extension is based on mean square stochastic calculus. ...

A Heuristic Algorithm Based on Monte Carlo Methods for the Rural Postman Problem

Fernández de Córdoba, Pedro; García-Raffi, L. M.; Sanchís Llopis, José María (Elsevier, 1998)

[EN] The Rural Postman Problem (RPP) consists of finding a minimum cost traversal of a specified are subset of a graph. Given that the RPP is a NP-hard problem, heuristic algorithms are interesting both to handle large ...
Mean square solutions of random linear models and computation of their probability density function

Jornet Sanz, Marc (Universitat Politècnica de València, 2020-03-05)

[EN] This thesis concerns the analysis of differential equations with uncertain input parameters, in the form of random variables or stochastic processes with any type of probability distributions. In modeling, the input ...
Measuring and improving eco-efficiency using Data Envelopment Analysis. A case study of Mahón-Menorca cheese

Sanjuán Pellicer, María Nieves; Ribal Sanchis, Francisco Javier; Clemente Polo, Gabriela; Fenollosa Ribera, M. Loreto (Wiley, 2011-08)

[EN] The concept of eco-efficiency can be defined with the "product value/environmental influence" ratio. Different models have been proposed to measure eco-efficiency. The main difference among them is the weighting system ...
Multilayer adsorption by Monte Carlo simulation

Molina Mateo, José; Salmerón Sánchez, Manuel; Monleón Pradas, Manuel; Torregrosa Cabanilles, Constantino (Elsevier, 2012)

[EN] Adsorption phenomena are characterized by models that include free parameters trying to reproduce experimental results. In order to understand the relationship between the model parameters and the material properties, ...
On the Contribution of Dense Multipath Components in an Intrawagon Environment for 5G mmW Massive MIMO Channels

Challita, Frédéric; Rodrigo Peñarrocha, Vicent Miquel; Rubio Arjona, Lorenzo; Reig, Juan; Juan-Llácer, Leandro; Pascual-García, Juan; Molina-García-Pardo, José-María; Liénard, Martine; Gaillot, Davy P. (Institute of Electrical and Electronics Engineers, 2019-12)

[EN] In this letter, the dependence of the specular multipath components (SMC) and dense multipath components (DMC) to the interuser spatial correlation and sum-rate capacity of a massive multiuser multiple-input--multiple-output ...
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 ...
Stochastic hydro-economic modeling for optimal management of agricultural groundwater nitrate pollution under hydraulic conductivity uncertainty

Peña Haro, Salvador; Pulido-Velazquez, M.; Llopis Albert, Carlos (Elsevier, 2011-08)

[EN] In decision-making processes, reliability and risk aversion play a decisive role. This paper presents a framework for stochastic optimization of control strategies for groundwater nitrate pollution from agriculture ...
