Using Fuzzy-Improved Principal Component Analysis (PCA-IF) for Ranking of Major Accident Scenarios. Systems Engineering [Internet]. 2020;45 :2235–2245.
Publisher's VersionAbstractThe industrial risk mapping is a topical problem in the field of risk management that attracts many researchers to develop risk matrices to ensure consultation between their actors. In this context, this paper aims to propose the principal component analysis (PCA) method as support for this consultation. Indeed, the use of PCA method is justified by its robustness for aggregate initial data associated with industrial risks as principal factors and ranking of this risk in terms of their criticalities in risk matrices. However, the aggregation of initial data on industrial risks by the main factors, in some cases, leads to inaccuracies which make it difficult to classify certain risks. This paper proposes two variants of PCA method to solve this inaccuracy and succeeds in classifying risks according to their respective criticalities, namely PCA-Improved (PCA-I) and PCA-I-Fuzzy (PCA-IF). The results come from the PCA application and its proposed variants (PCA-I and PCA-IF) on an example of accident scenarios ranking. We have established a scientific basis for the capitalization of mapping tool for consultation and decision support to industrial risk managers.

DYNAMIC MODELLING OFTHE BEHAVIOUR OF THE OUARKISS EARTHEN DAM UNDER SEISMIC LOADS. GeoScience Engineering [Internet]. 2020;66 (1) :40–52.
Publisher's VersionAbstract
The dynamic modelling of the behaviour of the Ouarkissearthen dam under seismic loads was performed using the finite elements method (FEM), with an approach in effective stresses. The soil behaviour is described by the Mohr-Coulomb criterion. A numerical method and a procedure of analysis are presented in this work. The seismic response of an earthen dam was evaluated. Particular emphasis is placed on the calculation of stresses, displacements, deformations and interstitial overpressures recorded during the seismic solicitation. It has been shown that numerical simulation is able to highlight the fundamental aspects of the displacements and deformations processes experienced by the structure ofdam and to produce preliminary results for the evaluation of the seismic behaviour of the structure taking into account the physical non-linearity of the materials constituting the body of the dam and the effect of the rigidity of the different zones of the dam and the foundation.

Altérité divine et étiolement de l'égo : Le théocentrisme dans la littérature soufie. Norsud [Internet]. 2020;16.
Publisher's VersionAbstractLe présent article propose de redéfinir les balises frontalières séparant la binarité tant radotée dans l’enceinte heuristique des sciences humaines et sociales à savoir : (altérité/égocentrisme), et ce à la lumière de la philosophie ésotérique musulmane qui tend à considérer ces deux acceptions, non dans un tiraillement antithétique, mais plutôt dans une symbiose fusionnelle interdépendante. Afin de mettre sur les rails notre entreprise, une lecture descriptiveanalytique des jets des ma{\^ıtres soufis, ayant scellé de leur empreinte la philosophie mystique religieuse, parait plus qu’impérative afin d’élucider et étayer notre dessein.

Compte-rendu De L'ouvrage:"la Mémoire Du Temps Chez Proust Et Beckett" Detrovato Vincent. Revue algérienne des lettres [Internet]. 2020;4 (2) :70-74.
Publisher's VersionAbstractil s’agit d’un compte rendu de l’ouvrage de TROVATO intitulé « La mémoire du temps chez Proust et Beckett ». L’auteur nous propose une étude transversale sur la mouvance de la notion « temps » dans deux chefs-d’øe}uvre qui ont marqué l’histoire de la littérature et les arts : « A la recherche du temps perdu » de Marcel Proust et « En attendant Godot » de Samuel Beckett. Qu’il s’agisse, en effet, de l’analyse de la valeur du temps ou le temps comme notion philosophique dans l’écriture, cet ouvrage permet une réflexion lucide sur l’impact du temps sur tout ce qui forme la scripto-genèse, la diègèse, la mémoire, la perception du monde et l’horizon d’attente.

Former à La Méthodologie De La Recherche à L’université : Quels Défis Pour Le Chercheur ?. Revue algérienne des lettres [Internet]. 2020;4 (3) :94-101.
Publisher's VersionAbstractEn sciences humaines et sociales, le cours de méthodologie de la recherche s’impose comme une matière indispensable dans le cursus universitaire. Sa maitrise garantit une crédibilité des projets réalisés et une ascension des travaux universitaires dans la sphère des recherches scientifiques. Toutefois, dans le domaine en question, la compétence méthodologique implique une prise compte de connaissances tous azimuts, nécessaires à l’élaboration du travail scientifique selon les règles requises par la communauté scientifique afin d’aboutir à la réussite universitaire. Une formation à la méthodologie de la recherche doit partir d’un diagnostic de la situation-problème dans laquelle se trouvent les étudiants pour pouvoir les surmonter. Cette contribution se veut une réflexion sur les défis à relever par le chercheur afin de réussir sa formation méthodologique et son projet de recherche.
