Modelling of the Acetification Stage in the Production of Wine Vinegar by Use of Two Serial Bioreactors
Álvarez Cáliz, Carmen María; Santos-Dueñas, Inés María; Jiménez Hornero, Jorge; García García, Isidoro (MDPI, 2020)In the scope of a broader study about modelling wine acetification, the use of polynomial black-box models seems to be the best choice. Additionally, the use of two serially arranged bioreactors was expected to result in ... -
Modelling of wine vinegar acetification bioreactor: Global sensitivity analysis and simplification of the model
Jiménez Hornero, Jorge; Santos-Dueñas, Inés María; García García, Isidoro (Elsevier, 2022)First-principles models of any process usually describe its complex underlying mechanisms using differential and algebraic equations including several unknown parameters, whose values must be normally estimated from ... -
Multifractal detrended fluctuation analysis of sheep livestock prices in origin
Pavón Domínguez, Pablo; Serrano, Salud; Jiménez-Hornero, Francisco José; Jiménez Hornero, Jorge; Gutiérrez de Ravé Agüera, Eduardo; Ariza Villaverde, Ana Belén (Elsevier, 2013)The multifractal detrended fluctuation analysis (MF-DFA) is used to verify whether or not the returns of time series of prices paid to farmers in original markets can be described by the multifractal approach. By way of ... -
Optimization of biotechnological processes. The acetic acid fermentation. Part I: The proposed model
Jiménez Hornero, Jorge; Santos-Dueñas, Inés María; García García, Isidoro (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 ... -
Optimization of biotechnological processes. The acetic acid fermentation. Part II: Practical identifiability analysis and parameter estimation
Jiménez Hornero, Jorge; Santos-Dueñas, Inés María; García García, Isidoro (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
Jiménez Hornero, Jorge; Santos-Dueñas, Inés María; García García, Isidoro (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 the Acetification Stage in the Production of Wine Vinegar by Use of Two Serial Bioreactors
Álvarez Cáliz, Carmen María; Santos-Dueñas, Inés María; Jiménez Hornero, Jorge; García García, Isidoro (MDPI, 2021)In the scope of a broader study about wine acetification, previous works concluded that using a single bioreactor hindered simultaneously reaching high productivities with high substrate consumption and the use of two ... -
Preparation of a pure inoculum of acetic acid bacteria for the selective conversion of glucose in strawberry purée into gluconic acid
Cañete Rodríguez, Ana María; Santos-Dueñas, Inés María; Torija-Martínez, María J.; Mas, Albert; Jiménez Hornero, Jorge; García García, Isidoro (Elsevier, 2015)Strawberry surpluses, which may account for about 20% of the whole production, could bean example of what is happening with other fruits. This surplus is largely transformed intostrawberry purée which, although is especially ... -
Revalorization of strawberry surpluses by bio-transforming its glucose content into gluconic acid
Cañete Rodríguez, Ana María; Santos-Dueñas, Inés María; Jiménez Hornero, Jorge; Torija-Martínez, María J.; Mas, Albert; García García, Isidoro (Elsevier, 2016)Modern societies produce massive surpluses of food, by-products and wastes that increase the interest for their revalorization. This work examines the use of a culture of Gluconobac-ter japonicus CECT 8443, without pH ... -
Simulation Tool for the Analysis of Cooperative Localization Algorithms for Wireless Sensor Networks
Ruz Ruiz, Mario L.; Garrido, J.; Jiménez Hornero, Jorge; Virrankoski, Reino; Vázquez Serrano, Francisco J. (MDPI, 2019)Within the context of the Internet of Things (IoT) and the Location of Things (LoT) service, this paper presents an interactive tool to quantitatively analyze the performance of cooperative localization techniques for ... -
Software Tool for Acausal Physical Modelling and Simulation
Jiménez Hornero, Jorge; Belmonte, Antonio; Garrido, J.; Ruz Ruiz, Mario L.; Vázquez Serrano, Francisco J. (MDPI, 2019)Modelling and simulation are key tools for analysis and design of systems and processes from almost any scientific or engineering discipline. Models of complex systems are typically built on acausal Differential-Algebraic ... -
Stiction compensation for low-cost electric valves
Vázquez, Francisco; Garrido, J.; Ruz, Mario L.; Jiménez Hornero, Jorge (Elsevier, 2023)Nonlinear dynamics of control valves, such as stiction, can produce significant performance degradation in the control loops where they are involved. There are several works in the literature describing and modelling these ... -
Structural identifiability of a model for the acetic acid fermentation process
Jiménez Hornero, Jorge; Santos-Dueñas, Inés María; García García, Isidoro (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 ...
