A Linux cluster of personal computers for the numerical simulation of natural airflows in greenhouses using a lattice model
(Elsevier, 2006)Some numerical models need a considerable computational effort to run their simulations. This fact is translated into long execution times delaying the decisions that have to be taken by the modeller in order to obtain the ... -

(Universidad de Córdoba, Vicerrectorado de Innovación y Calidad Docente, 2007)The aim of this article is to describe the implementation of the subject Electrical Technology in the new Campus Virtual Andaluz as a pilot experiment run by the Andalusian Regional Government for the university community. ... -
Estimating the mean acetification rate via on-line monitored changes in ethanol during a semi-continuous vinegar production cycle
(Elsevier, 2007)A simple, fast method for estimating the mean rate of biological oxidation in a typical semi-continuous wine vinegar production cycle was developed. The method involves on-line monitoring changes in ethanol concentration ... -
Structural identifiability of a model for the acetic acid fermentation process
(Elsevier, 2008)Modelling has proved an essential tool for addressing research into biotechnological processes, particularly with a view to their optimization and control. Parameter estimation via optimization approaches is among the major ... -
Optimization of biotechnological processes. The acetic acid fermentation. Part II: Practical identifiability analysis and parameter estimation
(Elsevier, 2009)In part I of this series a mathematical model for acetic acid fermentation was reported. However, no kinetic model can be complete until its equation parameters are estimated. This inevitably entails a practical identifiability ... -
Optimization of biotechnological processes. The acetic acid fermentation. Part III: Dynamic optimization
(Elsevier, 2009)Wine vinegar is obtained in a biotechnological process one of the crucial steps in which is the biological oxidation of the starting wine. Such a step is usually performed in a semi-continuous operation mode where a preset ... -
Optimization of biotechnological processes. The acetic acid fermentation. Part I: The proposed model
(Elsevier, 2009)Vinegar is a food product of increasing significance by virtue of its widely variable origin and uses (particularly as a condiment or food preservative). The gastronomic value of vinegar has been appreciated for thousands ... -
An educational computer tool for simulating long-term soil erosion on agricultural landscapes
(Wiley, 2009)Due to its economic and environmental impacts, soil erosion has been a major concern to farmers, engineers and policy makers in recent years. Water and tilling are two of the main agents responsible for this phenomenon and ... -
Object oriented modelling and simulation of hydropower plants with run-of-river scheme: A new simulation tool
(2009)This paper presents the design of a component library for modelling hydropower plants, and describes the development of a new simulation tool for small hydropower plants with a run-of-river scheme. After reviewing the ... -
