The fifth generation (5G) mobile communication technology intends to address the massively increasing data rate requirements as well as the massive growth in traffic volume. The 5G technologies achieve higher performance, reduced latency, higher density, and higher mobility minus of sacrificing reliability. However, as the mobile core networks are facing exponential growth in traffic and computing demand as smart devices and mobile applications become more popular. One of the most promising solutions to the challenges is caching. Non-Orthogonal Multiple Access (NOMA) is one of the promising radio access techniques for performance enhancement in next-generation cellular communications. Especially the 5G networks are expected to provide a massively increased number of users at a thousand times higher data rates at lower power consumption because NOMA provides a higher spectral efficiency and higher system throughput. For more improvement, power domain (PD-NOMA), code domain (CD-NOMA) and cooperative (C- NOMA) techniques are proposed and implemented in the 5G to overcome the future network demands. The PD-NOMA, employs Successive Interference Cancellation (SIC) at the receiver and Superposition Coding (SC) at the transmitter. The proposed systems implemented with the help of MATLAB and NYUSIM simulations. The results of simulation show that the proposed techniques meet the various needs of improved user fairness, quality-of-service (QoS), high reliability, high spectral efficiency, extensive connectivity, raising data rates, high flexibility, low transmission latency, massive connectivity, low delay, higher cell-edge throughput, and superior performance. For more improvement, caching techniques, as a storing popular reusable information at intermediate nodes to reduce backhauling load in wireless ii networks, have been integrated with C-NOMA to reduce the delay of storing planned content needs, relieve backhaul traffic and to alleviate the delay caused by handovers. The results of simulation of caching integrated with C-NOMA technique have shown promise in maximizing throughput, minimizing latency, and optimizing resource efficiency. In C-NOMA, dynamic resource allocation refers to the process of dynamically modifying the power required to transmit rates and resource blocks allocated to users under their QoS requirements and channel conditions. Finally, a novel approach is proposed by integrating C-NOMA, massive multiple-input multiple-output (m-MIMO) with caching as a strategic technique to overcome the exponential growth in data demand, spectrum scarcity, mitigation of interference, energy efficiency and sustainability. The simulation and evaluation results proved that the proposed system provides significantly a higher performance in terms of data rate, bit error rate (BER), and outage probability and reduces the power consumption to 52.6% and 54.7% compared to NOMA without cooperative and without NOMA, respectively, which is higher than the related works. The results of simulation verify the achievement of low-latency required by the sixth generation (6G) mobile communication networks cause to operate bandwidth-intensive applications such as high-definition video streaming, augmented reality, virtual reality, and Internet of Things (IoT) devices.

Dans le cadre de la recherche sur les transformations négatives des personnages et la transgression de l’écriture comme objectif élémentaire. Il s’agit aussi d’éclairer la présence des voix qui s’élèvent non seulement sur des problèmes identitaires mais aussi sur l’injustice sociale. Yasmina Khadra dans son œuvre « Qu’attendent les singes » a privilégié la critique noire à travers la notion de métamorphose génératrice de violence. C’est une nouvelle orientation vers la vérité qui se cache dans les labyrinthes et les impasses. A travers une approche sémiotique de la signification qui nous a permis de mettre à jour les enjeux socioculturels et politiques des personnages qui se transforment en individuel et pluriel.As part of the research on the negative transformations of the characters and aggression writing as a major goal. It is also to explain the existence of voices not only on issues of identity, but also on social injustice. Yasmina Khadra in his work "What monkeys wait for preferred the black criticism through the concept of generating violence transformation. This is a new direction towards the truth hidden in the maze and blocked roads. Through semiotic approach of the importance that allowed us to modernize social issues and cultural and political figures that turn into the individual and combined.

Afin de déterminer l’état du bassin de Seybouse (Nord-est Algérien) et le degré de pollution. Nous avons mené une étude écologique et systématique comprenant la réalisation d’un inventaire des macroinvertébrés benthiques pendant deux mois consécutifs (Mars, Avril). Nous avons remarqué que les trois sites échantillonnés Boumahra, Bentabouche et Oued Zimba, sont très riches en espèces.La faune recensée dans ce travail se compose de 44 taxons appartenant à quatre groupes qui sont : Annélides, Crustacés, Mollusques et les insectes aquatiques.Les résultats des analyses de la richesse et de la diversité ainsi que les indices biologiques de diversité et l’indice IBGN effectués sur les données obtenues montrent que : la station de Boumahra a une situation bonne de la qualité des eaux, une qualité moyenne pour la station de Bentabouche et la station d’Oued Zimba montre une qualité excellente

The dromedary camel (Camelus dromedarius) has large socio-cultural and economic importance in the arid lands of Tunisia. This zoogenetic resource hasbeen managed in a traditional mode, with a feeble selective pressure. In the insufficiency of genetic studies describing this population in Tunisia, the present research work affords foundations for the genetic improvement of this species. It offers a comprehensive description of the genetic variability, the structure and the recent history of this population. The genetic variability was investigated on the autosomal DNA, by amplifying 20 microsatellite markers, and on the mitochondrial DNA, by sequencing two mt DNA regions (the control region and cytochrome bgene). The nucleic markers analysis demonstrated a high level of variability and aweaksubstructure (FST= 0.02)of the Tunisi and romedary population. The known ecotypes, defined on the basis of phenotypic and morphologic characters, were faintly observed at the genetic level. The population showed a large admixture, close genetic distances and an important gene flow (Nm = 7) between the ecotypes and between the geographic areas. The population also exhibited a moderate inbreeding level (FIS= 0.2). The mitochondrial DNA analysis allowed the evaluation of the phylogeographic origin of the studied population. It proved that two maternal lineages are present at differential proportions. The most abundant haplotype (> 80 %) was identical to that largely present in most dromedary populations in Asian and African continents. The second lineage (5 %) was more genetically close to haplotypes recorded in the relatively isolated Eastern African dromedary population. In a final part of this study, we designed an efficient and affordable parentage assay to check camel This assay willafford the possibility of tracing back the genealogy of animals of high performance. Implications of the present genetic evaluation in the camel development plans were addressed. The study emphasized that thecameline genetic resources in Tunisia provide promising potential that ought to be exploited for sustainable food security in arid lands, through strategic and judicious management and development plans.
