Multifractal detrended fluctuation analysis of sheep livestock prices in origin
(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 ...
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 ...
A unified event-based control approach for FOPTD and IPTD processes based on the filtered Smith predictor
(Elsevier, 2017)
A new unified design of an event-based PID control architecture for self-regulating and integral processes is investigated in this work. The design is based on the Symmetrical-Send-On-Delta sampling technique (SSOD) and ...
A practical tuning methodology for event-based PI control
(Elsevier, 2014)
This paper is focused on the tuning of an event-based PI controller for first-order plus time delay systems(FOPTD). In this work, a novel design and combination of a controller and event generator with an easy-to-use tuning ...
Daylight Saving Time transitions and Cardiovascular Disease in Andalusia: Time Series Modeling and Analysis Using Visibility Graphs
(Sage, 2022)
The present study aimed to determine whether transitions both to and from daylight saving time (DST) led to an increase in the incidence of hospital admissions for major acute cardiovascular events (MACE). To support the ...
Preparation of a pure inoculum of acetic acid bacteria for the selective conversion of glucose in strawberry purée into gluconic acid
(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 ...
Influence of the final ethanol concentration on the acetification and production rate in the wine vinegar process
(Wiley, 2010)
BACKGROUND: The acetification process needs an overall study of the variables influencing it in order to establish their optimum values. Based on industrial experience and available literature, including a recently proposed ...
Gluconic acid: Properties, production methods and applications—An excellent opportunity for agro-industrial by-products and waste bio-valorization
(Elsevier, 2016)
Agro-industrial by-products and wastes pose serious, widespread problems with considerable economic and environmental consequences in developed countries. However, many of the by-products contain large amounts of sugars ...
Revalorization of strawberry surpluses by bio-transforming its glucose content into gluconic acid
(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 ...
An approach for estimating the maximum specific growth rate of Gluconobacter japonicus in strawberry purée without cell concentration data
(Elsevier, 2016)
The estimation of the maximum specific growth rate ( max) for non-readily culturable bacteria, growing on complex media containing suspended solids, is a difficult task considering the important problems in obtaining ...
