Application of multifractal wavelet analysis to spontaneous fermentation processes
(Elsevier, 2008)
"An algorithm is presented here to get more detailed information, of mixed cul-ture type, based exclusively on the biomass concentration data for fermentation processes. The analysis is performed with only the on-line ...
Inferring mixed-culture growth from total biomass data in a wavelet approach
(Elsevier, 2006)
"It is shown that the presence of mixed-culture growth in batch fermentation processes can be very accurately inferred from total biomass data by means of the wavelet analysis for singularity detection. This is accomplished ...
A robust estimation of the exponent function in the Gompertz law
(Elsevier, 2006)
"The estimation of the solution of a system of two differential equations introduced by Norton et al. (1976) that is equivalent to the famous Gompertz growth law is performed by means of the recent adaptive scheme of ...
Anchorage of small cluster of manganese oxide, zinc oxide and silver on nitrogen doped and functionalized carbon nanotubes
(2008)
"Los nanotubos de carbono de pared múltiple (MWCNTs) exhiben excelentes propiedades mecánicas y electrónicas. Debido a su estructura y tamaño, los MWCNTs podrían ser utilizados como sustratos para la deposición de ...
Online monitoring of Mezcal fermentation based on redox potential measurements
(2009)
"We describe an algorithm for the continuous monitoring of the biomass and ethanol concentrations as well as the growth rate in the Mezcal fermentation process. The algorithm performs its task having available only the ...
PI-controlled bioreactor as a generalized Liénard system
(Elsevier, 2007)
"It is shown that periodic orbits can emerge in Cholette’s bioreactor model working under the influence of a PI-controller. We find a diffeomorphic coordinate trans-formation that turns this controlled enzymatic reaction ...
A simple electronic circuit realization of the tent map
(2009)
"We present a very simple electronic implementation of the tent map, one of the best-known discrete dynamical systems. This is achieved by using integrated circuits and passive elements only. The experimental behavior of ...
An amplitude-phase (Ermako-Lewis) approach for the Jackiw-Pi model of bilayer graphene
(2009)
"In the context of bilayer graphene we use the simple gauge model of Jackiw and Pi to construct its numerical solutions in powers of the bias poten-tial V according to a general scheme due to Kravchenko. Next, using this ...
Classical harmonic oscillator with Dirac-like parameters and possible applications
(2004)
"We obtain a class of parametric oscillation modes that we call K-modes with damping and absorption that are connected to the classical harmonic oscillator modes through the “supersymmetric” one-dimensional matrix procedure ...
