Influence of calcium substitution on structural, morphological and electrical conductivity properties of La1- xCaxNi0.5Ti0.5O3 (x = 0.0, x = 0.2) compounds for energy storage devices

Sirine Gharbi, Ahmadou Ly, Essebti Dhahri, Régis Barillé, Driss Lahem, Marc Debliquy, Mohamed Rguiti

This paper explores the effect of calcium insertion on the physicochemical properties of La1-xCaxNi0.5Ti0.5O3 (x = 0.0 (LNTO), x = 0.2 (LCNTO)) compounds fabricated by the sol–gel process. The samples crystallize in an orthorhombic distorted structure with the Pnma space group. The purity and…

A sufficient condition to design unknown input observers for nonlinear systems with arbitrary relative degree

Pedro Coutinho, Iury Bessa, Wen‐bo Xie, Tran Anh-Tu Nguyen, Reinaldo Martínez Palhares

Abstract This article addresses the problem of state and unknown inputs (UIs) estimation for nonlinear systems with arbitrary relative degree with respect to the UIs. For this purpose, a novel nonlinear unknown input observer (UIO) is proposed, which is able to decouple the UIs by using the…

Evaluation of Flow and Heat Transfer During Compression Stroke in a Porous Material Using MVCEF Solving Method

Inès Marzougui, Ramla Gheith, Houda Hachem, Fethi Aloui

Abstract This work deals with CFD modeling method under Fortran 90 with dimensionless setting. A numerical study of flow and heat transfer inside a cylinder partially filled with a porous material and with two pistons is provided during compression stroke. Phase shift between the two pistons is…

Study of Couette-Taylor-Poiseuille Flow With a Wavy Internal Cylinder Surface at Low Taylor and Axial Reynolds Numbers

Lamia Gaied, Emna Berrich, Fethi Aloui

Abstract The flow models of a Taylor-Couette-Poiseuille flow with a wavy interior surface have been studied at low axial Reynolds numbers (Reax less than or equal to 32) and Taylor numbers (Ta less than or equal to 606). Two types of surfaces were operated; smooth and wavy. The surface of the wavy…

Las protestas del 11 de julio de 2021 en Cuba: ¿un acontecimiento singular?

Orlando Manzano Guerrero

Dans le concert des nations d'Amérique latine et des Caraïbes, avec lesquelles elle partage une géographie commune et une grande partie de son histoire, Cuba se distingue par certaines particularités qui en font un cas unique. Sa trajectoire historique tout au long du XXe siècle - et, en…

Cascade Takagi–Sugeno fuzzy observer design for nonlinear uncertain systems with unknown inputs: A sliding mode approach

Cuong Nguyen, Anh‐tu Nguyen, Sebastien Delprat

This article investigates the design of Takagi–Sugeno (TS) fuzzy model-based observers for nonlinear systems with parametric uncertainties and unknown inputs. To address this challenging problem, two observers are constructed in cascade. Based on the sliding mode technique, the first observer…

An Efficient Lattice Boltzmann Model for 3D Transient Flows

Raoudha Chaabane, Abdelmajid Jemni, Fethi Aloui

In this paper, we report on the development and the implementation of the mesoscopic approach based on the Lattice Boltzmann method (LBM) in order to simulate three-dimensional coupled modes of thermal and fluid flows. First the lattice Boltzmann method (LBM) has been used to solve transient heat…
