Takagi-Sugeno Fuzzy Representation to Modelling and State Estimation

Mohammed Chadli, Thierry-Marie Guerra, Ivan Zelinka

This chapter shows the interest of Takagi-Sugeno (T-S) fuzzy model approach to apprehend nonlinear behaviors of physical systems and its application for observers design. From mathematical nonlinear model or experimental data, a T-S representation can be obtained using different techniques. This…

Option pricing with constant elasticity of variance (CEV) model

Rajae Aboulaich, M. L. Hadji, Abdelilah Jraifi

In this work we propose an approximate numerical method for pricing of options for the constant elasticity of variance (CEV) diffusion model. We prove firstly the existence and uniqueness of the solution in weighted Sobolev space, and then we propose the finite element method and finite difference…

Lower and upper solutions for the heat equation on a polygonal domain of R2

Colette De Coster, Serge Nicaise

We consider the nonlinear periodic-Dirichlet heat equation on a polygonal domain of the plane in weighted Lp-Sobolev spaces equation presented Here f is Lp(0; T;Lpμ(Ω)-Caratheodory, where L pμ(Ω) = {v ε Lploc(Ω) : rμv ε Lp(Ω)}, with a real parameter μ and r(x) the distance from x to the set of…

Spectral analysis and exponential or polynomial stability of some indefinite sign damped problems

F. Abdallah, D. Mercier, Serge Nicaise

In this paper, we consider two damped wave problems for which the damping terms are allowed to change their sign. Using a careful spectral analysis, we find critical values of the damping coefficients for which the problem becomes exponentially or polynomially stable up to these critical values.

Trust and risk management towards resilient large-scale Cyber-Physical Systems

Arnaldo E Pereira, Nelson Rodrigues, José Barbosa, Paulo Leitão

Empowering distributed entities with decisional and adaptation capabilities is the current trend in control systems operating in highly changing environments. Cyber-Physical Systems (CPS) is a paradigm addressing this challenge as it allows the integration of both physical and decisional parts. By…

Towards a quality model for the evaluation of DSS based on KDD process

Emna Ben Ayed, Mounir Ben Ayed

A Decision Support System (DSS) based on Knowledge Discovery from Data (KDD) process is used to give confident knowledge to the final users in order to help them making right decisions. Such systems can be underused if the mined knowledge is unconfident, or if the system is hardly usable or…

A survey of cross-layer power-reliability tradeoffs in multi and many core systems-on-chip

Ahmed Eltawil, Michael Engel, Bibiche Geuskens, Amin Khajeh Djahromi, Fadi Kurdahi, Peter Marwedel, Smail Niar, Mazen Saghir

As systems-on-chip increase in complexity, the underlying technology presents us with significant challenges due to increased power consumption as well as decreased reliability. Today, designers must consider building systems that achieve the requisite functionality and performance using components…

An analysis of the robot collision avoidance using the programming through imitation

Aurel Fratu, Michel Dambrine

This paper presents an analysis of the collision avoidance of the cooperative robots using the programming through imitation. Each physical robot acts fully independently, communicating with cor- responding virtual prototype and imitating her behavior. Each physical robot reproduces the motion of…

Design of Biorthogonal Filter Banks Using a Multi-objective Genetic Algorithm for an Image Coding Scheme

Abdelkader Boukhobza, Abdennacer Bounoua, Abdelmalik Taleb-Ahmed, Nasreddine Taleb

In this paper, we present an optimization method based on a multi-objective Genetic Algorithm (GA) for the design of linear phase filter banks for an image coding scheme. To be effective, the filter banks should satisfy a number of desirable criteria related to such a scheme. Instead of imposing…

Analysis and Control of Underactuated Mechanical Systems

Amal Choukchou-Braham, Brahim Cherki, Mohamed Djemai, Krishna Busawon

This monograph provides readers with tools for the analysis, and control of systems with fewer control inputs than degrees of freedom to be controlled, i.e., underactuated systems. The text deals with the consequences of a lack of a general theory that would allow methodical treatment of such…
