Towards large-scale face-based race classification on spark framework. Multimedia Tools and ApplicationsMultimedia Tools and Applications. 2019;78 :26729–26746.
AbstractRecently, the identification of an individual race has become an important research topic in face recognition systems, especially in large-scale face images. In this paper, we propose a new large-scale race classification method which combines Local Binary Pattern (LBP) and Logistic Regression (LR) on Spark framework. LBP is used to extract features from facial images, while spark’s logistic regression is used as a classifier to improve the accuracy and speedup the classification system. The race recognition method is performed on Spark framework to process, in a parallel way, a large scale of data. The evaluation of our proposed method has been performed on two large face image datasets CAS-PEAL and Color FERET. Two major races were considered for this work, including Asian and Non-Asian races. As a result, we achieve the highest race classification accuracy (99.99%) compared to Linear SVM, Naive Bayesian (NB), Random Forest(RF), and Decision Tree (DT) Spark’s classifiers. Our method is compared against different state-of-the-art methods on race classification, the obtained results show that our approach is more efficient in terms of accuracy and processing time.

Two dimensional ElGamal public key cryptosystem. Information Security Journal: A Global PerspectiveInformation Security Journal: A Global Perspective. 2019;28 :120-126.
AbstractIn this work, we propose a secure version of ElGamal public key cryptosystem, and prove that it is semantically secure assuming the hardness of what we call the two-dimensional decisional Diffie-Hellman (2DDDH) problem, this cryptosystem is distinguished by the speed of encryption and decryption processes and by its resistance to active adversaries. Since the 2DDDH problem is harder than the decisional Diffie-Hellman (DDH) problem (as it will be seen), one may conclude that our model reinforces the exchange security compared to the existed cryptosystems falling within the same context, also we discuss the difficult problems that guarantee its security.

Apprentissage du FLE en Algérie: de l’analyse des représentations à la motivation des apprenants dans le milieu universitaire. Para lá da tarefa: implicar os estudantes na aprendizagem de línguas estrangeiras no ensino superior. Porto: FLUP [Internet]. 2019 :208-225.
Publisher's VersionAbstract
La dynamique motivationnelle est-elle tributaire de l’évolution des représentations ? Quel rapport existe-t-il entre les représentations des étudiants vis-à-vis de la langue/culture française et l’apprentissage de celle-ci ? C’est à ces questions que la présente recherche tente de répondre. Pour cela, nous avons, dans un premier temps, réalisé à travers une enquête par questionnaire, une étude comparative entre les représentations qu’ont les étudiants de première année licence du département de français (Université de Batna 2) de la langue/culture française au début et en fin de l’année ; notre objectif étant d’examiner l’effet de l’évolution de leurs représentations sur leurs motivations. Afin d’appuyer les résultats obtenus de l’analyse des questionnaires, nous avons, dans un second temps, effectué des entretiens semi-directifs avec leurs enseignants. Au terme de cette étude, nous avons constaté une évolution de la motivation des étudiants qui s’explique par l’évolution de leurs représentations vis-à-vis de la langue/culture cible.

L’hydrologie tributaire du relief est la conséquence directe des eaux d montre un domaine allochtone résultant d’une h atlasique et alpine. Ce dernier est caractérisé par des séries sédimentaires carbonatées colmaté par d'abondantes formations terrigènes.

Characterization of gypsy moth Lymantria dispar (Linnaeus, 1758)(Lepidoptera Lymantriidae) eggs in Cork oak forests of the Kabylie region (Jijel-Algeria). Biodiversity Journa [Internet]. 2019;10 (4) :569–576.
Publisher's VersionAbstract
Algerian oak forests, extending over the entire northern littoral region, are attacked episodically by many defoliating Lepidoptera, of which Lymantria dispar (Linnaeus, 1758) (Lepidoptera Limantriidae) is the most widespread. In our study we aim to highlight the action of the changes of trophic factors on the dynamics of the population of Lymantria dispar through field inventory methods. Namely: the eggs counting by the line-transect method, picking of the eggs, control of eggs quality. Carried out on two stations in the Kabylie region (Jijel), in the forest of Béni Ider El M’sid (Taher) and that of the Ouled Djendjen Canton Boudouda (Texanna). The obtained results show that Texanna station is distinguished by a very high non-viable egg rate compared to Taher station, this is caused by the difference between the phenology of Lymantria dispar and the host tree which is affected in its foliage by various factors whose altitude is one of these factors

Convective Solar Drying of Spinach Leaves (Spinacia oleracea). MOJ Food Processing & Technology [Internet]. 2019;7 (1).
Publisher's VersionAbstract
The drying on of the means is usually used which allows the conservation of the food products by lowering of the activity of water. This paper presents the results of an experimental spinach (Spinacia oleracea) drying study in a new solar dryer. It is an indirect solar dryer with forced convection was developed and improved at the Food Science laboratory. Drying spinach leaves to a final moisture content of 2% from 93.2% (wet basis), with an air-drying speed equal to 1m/s. This study made it possible to determine the drying kinetics of spinach leaves, the evolution of the temperature profile and the influence of drying air recycling (0, 50 and 90%) on drying time. The curves of drying obtained show that the drying rate increased marginally with the increase in fraction of air recycled. It is reduced 3 to 4 hours, by increasing the fraction air recycled from 50 to 90 % respectively, with a significant profit of thermal energy. The drying temperature is higher and stable in the drying chamber of the order of 55 to 65°C (90% air recycled).
