Granular Biomass Floatation: A Simple Kinetic/Stoichiometric Explanation
(2017)
Floatation events are commonly observed in anammox, denitrifying and anaerobic granular systems mostly subjected to overloading conditions. Although several operational strategies have been proposed to avoid floatation of ...
Let's defend dichato! Common goods and territorial conflict in chilean coastal areas
(2017)
The Civil Code of the Republic of Chile established that fishermen could make use of the sea beaches for their fishing activities, thereby defining a coastline space of independent common use for the neighboring owners, ...
Magnetic corrections to pi-pi scattering lengths in the linear sigma model
(2018)
In this article, we consider the magnetic corrections to pi-pi scattering lengths in the frame of the linear sigma model. For this, we consider all the one-loop corrections in the s, t, and u channels, associated to the ...
Combining fractional order operators and adaptive passivity-based controllers: an application to the level regulation of a conical tank
(2017)
In this paper, fractional order (FO) operators and adaptive passivity-based controllers (APBC) are combined. The main aim is to explore possible advantages of combining FO operators and APBC over the use of integer order ...
Comments on "fractional order lyapunov stability theorem and its applications in synchronization of complex dynamical networks''
(2015)
This letter shows an incorrect application of the chain rule for fractional order derivatives reported in paper (Chen et al., 2014). Due to this misleading application, the proof of Theorem 2 and Theorem 5 in Chen et al., ...
Adaptive Synchronization Of Fractional Lorenz Systems Using A Reduced Number Of Control Signals And Parameters
(2016)
This paper analyzes the synchronization of two fractional Lorenz systems in two cases: the first one considering fractional Lorenz systems with unknown parameters, and the second one considering known upper bounds on some ...
Taylor Polynomial Approximation And Adaptive Passivity-Based Control Applied To The Level Regulation Of A Conical Tank
(2017)
The techniques of Taylor polynomial approximation (TPA) and adaptive passivity-based controller (APBC) are combined in this study and applied to the level regulation of a conical tank. The design and comparative experimental ...
Control Of A Grinding Mill Circuit Using Fractional Order Controllers
(2017)
This paper presents the design and application of fractional single-input-single-output (SISO) controllers to a grinding mill circuit, which is a multiple-input-multiple-output (MIMO) process. Two kinds of controllers are ...
Boundedness and convergence on fractional order systems
(2016)
We establish conditions to guarantee boundedness and convergence of signals described by non integer order equations using Caputo derivatives. The case of linear time-varying unforced equations is first studied, and later, ...
On the lyapunov theory for fractional order systems
(2016)
We provide the main features of Lyapunov theory when it is formulated for fractional order systems. We give consistent extensions of Lyapunov, LaSalle and Chetaev classical theorems to the case of fractional order systems. ...
