Quantification of total phenols, flavonoides and tannins from Ziziphus jujuba (mill.) and Ziziphus lotus (l.) (Desf). Leaf extracts and their effects on antioxidant and antibacterial activities

open access: yesInternational Journal of Secondary Metabolite, 2017
This work was performed to determine the biochemical composition, antioxidant and antimicrobial activities of leaf extracts collected from four different provenances: Mahdia and Mahres (Ziziphus jujuba); Kairouan and Rouhia (Ziziphus lotus).

Vehicular Applications of Koopman Operator Theory—A Survey

open access: yesIEEE Access, 2023
Koopman operator theory has proven to be a promising approach to nonlinear system identification and global linearization. For nearly a century, there had been no efficient means of calculating the Koopman operator for applied engineering purposes.

On-line Bayesian system identification [PDF]

open access: yes2016 European Control Conference (ECC), 2016
We consider an on-line system identification setting, in which new data become available at given time steps. In order to meet real-time estimation requirements, we propose a tailored Bayesian system identification procedure, in which the hyper-parameters are still updated through Marginal Likelihood maximization, but after only one iteration of a ...

On Identification of Cascade Systems

open access: yesIFAC Proceedings Volumes, 2008
The objective of this contribution is to discuss some aspects of system identification of cascade systems. Models of such systems are important in for example cascade control applications.

Accuracy analysis of a covariance matching method for continuous-time errors-in-variables system identification

open access: yes, 2012
A covariance matching method for continuous-time errors-in-variables system identification from discrete-time data is analyzed. The asymptotic normalized covariance matrix, valid for a large number of data and a small sampling interval, is evaluated ...

Distributed system identification with ADMM [PDF]

open access: yes53rd IEEE Conference on Decision and Control, 2014
This paper presents identification of both network connected systems as well as distributed systems governed by PDEs in the framework of distributed optimization via the Alternating Direction Method of Multipliers. This approach opens first the possibility to identify distributed models in a global manner using all available data sequences and second ...

Uncertainty in Identification Systems

open access: yes2018 IEEE International Symposium on Information Theory (ISIT), 2018
We study the high-dimensional identification systems under the presence of statistical uncertainties. The task is to design mappings for enrollment and identification purposes. The identification mapping compresses users' information then stores the index in the corresponding position in a database.

The social system identification problem [PDF]

open access: yes2015 54th IEEE Conference on Decision and Control (CDC), 2015
The focus of this paper is modeling what we call a Social Radar, i.e. a method to estimate the relative influence between social agents, by sampling their opinions and as they evolve, after injecting in the network stubborn agents. The stubborn agents opinion is not influenced by the peers they seek to sway, and their opinion bias is the known input to

On the smoothness of nonlinear system identification [PDF]

open access: yesAutomatica, 2020
We shed new light on the \textit{smoothness} of optimization problems arising in prediction error parameter estimation of linear and nonlinear systems. We show that for regions of the parameter space where the model is not contractive, the Lipschitz constant and $β$-smoothness of the objective function might blow up exponentially with the simulation ...
