No full textBased on the critical literature as well as on observations collected by the author for the preparation of his Ph. D. thesis, the article addresses the definition and the characterization of the main types of informal employment, the status of work in Morocco, and examines in more detail some atypical forms of work and employment which are related to the operation of French enterprises located in this country (the “ chaouch”, the maid, the …).L’article interroge la définition et les formes du travail informel dans le contexte sociétal marocain à partir de la littérature critique et des observations recueillies dans le cadre d’une thèse de doctorat en Sociologie. A la lumière des données collectées, on développe quelques remarques sur le statut du travail dans la société marocaine et on examine de façon plus précise la problématique du maintien de certaines figures atypiques en relation avec les entreprises françaises délocalisées au Maroc («chaouch » , bonne, porteur).Labari Brahim.

Real-Time Fault Detection and Identification for MMC Using 1-D Convolutional Neural Networks
No full textAutomated early detection and identification of switch faults are essential in high-voltage applications. Modular multilevel converter (MMC) is a new and promising topology for such applications. MMC is composed of many identical controlled voltage sources called modules or cells. Each cell may have one or more switches and a switch failure may occur in anyone of these cells. The steady-state normal and fault behavior of a cell voltage will also significantly vary according to the changes in the load current and the fault timing. This makes it a challenging problem to detect and identify such faults as soon as they occur. In this paper, we propose a real-time and highly accurate MMC circuit monitoring system for early fault detection and identification using adaptive one-dimensional convolutional neural networks. The proposed approach is directly applicable to the raw voltage and current data and thus eliminates the need for any feature extraction algorithm, resulting in a highly efficient and reliable system. Simulation results obtained using a four-cell, eight-switch MMC topology demonstrate that the proposed system has a high reliability to avoid any false alarm and achieves a detection probability of 0.989, and average identification probability of 0.997 in less than 100 ms. - 2018 IEEE.Manuscript received October 23, 2017; revised February 11, 2018 and March 27, 2018; accepted April 16, 2018.

TEACHING COMPETENCIES AND THEIR ROLE IN THE DEVELOPMENT OF SOME SKILLFUL QUALITIES OF YOUNG CHILDREN
No full textThis study aimed to investigate the use of teaching competences and its role on the development of basic motor skills of primary school children (from 6 to 7 years old). The sample population consisted of 40 pupils (girls and boys), the researcher have found that: (1), the formation of goals within teaching by competences units in the form of skills are easy to be identified and distinguished with the use of a level of acceptance for the performance (efficiency indicators) and (2), the impact of teaching by competences units through different performances of the skills, the static kinetic conditions and dynamic ones in the improvement of the capacity to held up the constancy of the body, and the capacity to overcome the impact of gravitational forces for the experimental sample

Sminthurinus signatus
No full textSminthurinus signatus (Krausbauer, 1898) Sminthurus aureus var. signata Krausbauer, 1898: 496. Sminthurinus signatus – Deharveng 1976: 81. NEW DATA. — First record of the species for Algeria. DISTRIBUTION. — Probably Europe (not recognized in Bretfeld 1999). REMARK Very rare in our samples. The literature about this species is confusing. It is listed in Bretfeld (1999), who follows Stach (1956), as a subspecies of Sminthurinus elegans, with Krausbauer, 1902 given as author. In fact, it was described by this last author as Sminthurus aureus var. signata in 1898, and briefly but clearly characterized by its color pattern. It is very characteristic and common in western Europe (Thibaud 2017), and fully deserves a specific status.

Orality as Aesthetic Device: Articulating Language, Religion, and Authority in Mohamed Akounad’s Tawargit d Imik
No full textThis article explores Mohamed Akounad\u27s novel Tawargit d imik, which focuses on protagonist Ssi Brahim who struggles to convey the essence of his religious sermons to an exclusively amazigh audience amidst societal opposition. By examining Ssi Brahim\u27s character as the author\u27s alter ego, the study aims to assess the novel\u27s portrayal of religious concerns and activism for Tamazight and identity, particularly in relation to orality. Employing a sociolinguistic approach drawing from Bourdieu\u27s Language and Symbolic Power, the analysis delves into the intersection of religion, authority, and language, placing orality at the heart of their role within the narrative. This study proposes a dual analytical approach, comprising textual and transtextual analyses, in order to unravel the protagonist\u27s journey and explore intertextual connections with sacred texts.

Design and implementation of a power supply for MEMS vaporizing liquid microthrusters
No full textThis thesis presents the design of an accurate current source for MEMS vaporizing liquid microthrusters. An analysis of different power supplies is presented. The design choices leading to the implemented current sink topology is given. The main components, which are an op-amp, a MOSFET and a resistor, are analyzed extensively. System integration tests showed that the current source worked adequately. The current source has also been tested separately and the imposed accuracy requirement is not met. The reason for this has to be further investigated, as there are many potential sources of errors which can cause deviations in the order of microampere. Lastly, several recommendations are given for improving the system.Real-time data acquisition of a heater/temperature sensor array and pressure sensors for performance evaluation of MEMS vaporizing liquid micro-thrusters in nanosatellitesElectrical Engineerin
