FRW barotropic zero modes: dynamical systems observability
(2007)
"The dynamical systems observability properties of barotropic bosonic and fermionic FRW cosmological oscillators are investigated. Nonlinear techniques for dynamical analysis have been recently developed in many engineering ...
Supersymmetric free-damped oscillators: adaptive observer estimation of the Riccati parameter
(2006)
"A supersymmetric class of free damped oscillators with three parameters has been obtained in 1998 by Rosu and Reyes through the factorization of the Newton equation. The supple-mentary parameter is the integration constant ...
Detection of mixed-culture growth in the total biomass data by wavelet transforms
(2010)
"We have shown elsewhere that the presence of mixed-culture growth of microbial species in fermentation processes can be detected with high accuracy by employing the wavelet transform. This is achieved because the crosses ...
Nonlinear software sensor for monitoring genetic regulation processes with noise and modeling errors
(2005)
"Nonlinear control techniques by means of a software sensor that are commonly used in chemical engineering could be also applied to genetic regulation processes. We provide here a realistic formulation of this procedure ...
High-gain nonlinear observer for simple genetic regulation process
(Elsevier, 2007)
"High-gain nonlinear observers occur in the nonlinear automatic control theory and are in standard usage in chemical engineering processes. We apply such a type of analysis in the context of a very simple one-gene reg-ulation ...
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 ...
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 ...
