    Biométrie résiliables peuvent être une bonne approche pour répondre aux préoccupations de sécurité et de confidentialité sur l'authentification biométrique. Elle utilise des transformations paramétrées pour convertir un modèle biométrique original dans une nouvelle version pour l'authentification. La sécurité de la biométrie résiliable se cache dans la non-invertibilité du modèle transformé, de sorte que le modèle d'origine ne peut pas être récupéré. Une façon d'atteindre cette caractéristique est par l'utilisation d¿une fonction de transformation plusieurs-à-un. Dans ce travail on a analysé l¿algorithme de sécurisation de modèle d¿empreinte digitale proposé par Chouaib et al. (2014) basé sur la conversion des données biométriques en représentation de coque (shell). Cet algorithme présente plusieurs failles de sécurité, on a décrit un algorithme d¿attaque permettant de récupérer les données originales à partir de modèles protégés par l¿algorithme de coque. Cela se traduit par la récupération possible de minuties d'origine à partir d¿un modèle transformé.

    Depuis plusieurs années beaucoup de travaux de recherche considérables sont menés pour analyser et perfectionner la détection radar. Cependant, la difficulté qui se pose est de trouver un algorithme de traitement qui s'adapte à une variété d'environnements. Un concept important qui est en liaison avec les propriétés géométriques d¿un objet est la géométrie fractale. Cette géométrie, qui décrit bien les objets complexes et irréguliers avec son paramètre important "la dimension fractale", a été utilisée dans la détection radar. Dans le cadre de notre thèse, nous avons proposé un nouveau détecteur radar basé sur l'utilisation de la dimension fractale, estimée par la méthode de comptage des boîtes, et adaptée à plusieurs types de clutter de mer et de terre. Le processus de formation d'une image SAR s¿effectue à partir de données brutes. De multiples d¿algorithmes ont été développés. Dans ce travail, nous avons utilisé trois algorithmes; l¿algorithme à filtrage adapté (Matched Filter Algorithm MFA), l'algorithme de rétroprojection (Back Projection Algorithm BPA) et l¿algorithme de format polaire (Polar Format Algorithm PFA) pour former des images SAR expérimentales.

    The study focused on the diagnosis of gastropods and pelecypods classes species, mostly in the planktonic larvae stage, to be used as evidence of marine transgression of mid-Holocene in Southern Iraq. Three biofacies were identified depending on microfossils (planktonic larvae) primarily as well as the nature of sediments. They were defined as Biofacies1 (B1), Biofacies2 (B2) and Biofacies3 (B3). Three biofacies were identified depending on microfossils (planktonic larvae) primarily as well as the nature of sediments. They were defined as Biofacies1 (B1), Biofacies2 (B2) and Biofacies3 (B3). where Biofacies1 (B1) can be placed within the marine transgression unit that occurred in middle of the Holocene, While Biofacis2 (B2) can be considered within the marine regression unit, which is approximately 4000 Yr BP, and the Biofacies3 (B3) may indicate that the occurrence of fluctuation in the sea level at the end of Holocene.

    « L'image du handicapé dans Les jours de Taha Hussein et Le Cri de la mouette d'Emmanuelle Laborit: étude comparée.» est le thème principal de cet ouvrage. Le corpus choisi renferme la trilogie arabe de Taha Hussein intitulé: Les jours (''Le Livre des jours'' et ''La traversée intérieure''). De côté français, Le Cri de la mouette d'Emmanuelle Laborit. Les approches suivies sont l'approche sociocritique, psychologique, autobiographique, thématique et narratologique. L'investigation principale est de déchiffrer les deux autobiographies en vue d'analyser la configuration et la représentation des personnes en situation de handicap dans la littérature, leur attitude envers leur entourage, leur relation à la société, les problèmes sociaux et les obstacles qui entravent leur succès et leurs réactions en face de tous ces obstacles. La cécité et la surdité sont bien analysées comme deux handicaps à travers l'aveugle Taha Hussein et la sourde Emmanuelle Laborit. Leur démarche est extraordinaire et un exemple à suivre en ce qui concerne le succès, le défi, la célébrité et la conscience qu'ils ont voulue répandre non seulement aux handicapés, mais aussi aux personnes naturelles.

    La mondialisation de nos sociétés au XXIème siècle a bouleversée nos modes de vie traditionnels, la culture et l¿identité de la région de Kabylie en Algérie s¿est vue dépassée, oubliée par les jeunes d¿aujourd¿hui qui ne se reconnaissent plus à leurs ancêtres, leur langue maternelle n¿est plus parlée et discutée dans les foyers autours d¿une table, en famille, elle est remplacée par la langue française héritée du colonialisme. Le paysage même de la Kabylie a changé, laissant place aux bâtiments et aux villas, disant adieu aux maisons et à l¿agriculture d¿antan, la collecte des olives ne se faisant plus. Ce qui nous intéresse dans cette réflexion c¿est l¿identité berbère qui s¿est vu oubliée à cause d¿un brassage culturel, car, au rendez-vous du donner et du recevoir culturel, les choses semblent ne plus marcher comme elles se doivent. Le choc culturel, ce « sentiment de profonde désorientation qu'éprouvent les personnes et les groupes mis soudainement en contact avec un milieu culturel dont les traits se révèlent inconnus, incompréhensibles, menaçants » , a provoqué dans nos sociétés modernes des grandes mutations.

    Diabetes mellitus is becoming a worldwide epidemic. Epidemiologists estimate that by 2025 diabetes will affect 300 million people, with about half of them from the Asia Oceania region alone. During this time, there will be three-fold increase of this disease in Asia, both in developed countries like China and India, and in the rapidly developing countries, such as Malaysia and Singapore. In the last two decades, Malaysia has undergone rapid growth, registering an improved quality of life, a reduced mortality rate, and an increased median age. Unfortunately, this great progress also makes Malaysia highly prone to the diabetes epidemic. The ratio of the diabetic patients who can achieve the target glycaemic control is varied from one population to another. This depends on many factors; the treatment and the patients compliance to the treatment are part of these factors.

    We live in an era characterized by attitudes and behaviors' fluctuations. Indeed, nowadays consumers don't necessarily go to stores to buy something clearly defined. But, they go to explore, look, compare, hang out...The influence of environmental characteristics on individuals' behavior has long been exploited by architects, retailers, and interior designers. Over the years, it has become clear that environmental variables can significantly influence consumer behavior and emotions. The atmosphere on a retail space is composed of different elements that are often called "store atmospherics" such as music, scent, and colors on which the retailer should act to impact the consumers' behavior. This book focuses on environmental psychology for the explanation and interpretation of store atmospherics and its impact on consumer behavior. With a collection of empirical studies that summarizes all previous research on the influence of colors, music, and crowding on consumer behavior within stores, the book highlights the methodological challenges inherent in this field of research.

    A large number of cultural practices and environmental conditions affect bulbing, flowering and seed development in onion. The main factors affecting seed yields are high temperature and water stress during pollination and seed development. The quality of seed is not good enough and most of the times there have been problems related to germination capacity of the seeds and true to typeness. The problem is further exacerbated by the short shelf life of onion seed (one year under favorable condition). This book is largely based upon investigations by the researchers and reviews onion work on the effects of temperature and photoperiod, soil conditions, seedling size, bulb size, set size, plant density, plant nutrition, water supply, plant hormones, weed infestation, pollination, and genes responses that affect bulbing and flowering to provide the readers with an applied field-based perspective (older research) with some of the newer research that has been done. The present work is designed for the use of investigators and producers as well as to meet the needs of students.

    Panegyrics on the Holy Prophet (PBUH) occupy a significant place in the realm of Islamic literature and in the loyalty to the Holy Prophet (PBUH). Each and every Muslim is expected to cultivate the most ardent love and the highest respect for the Leader of Islam of the two worlds. During the time of the Holy Prophet (PBUH),Panegyrics and odes were recited in his gracious presence, and the Holy Prophet (PBUH) appreciated and encouraged. Spiritual attraction towards Prophet Mohammed (PBUH) has been a key inspiration for producing countless qualified literary works in all languages throughout ages. Literature extolling Prophet Mohammed (PBUH) has contributed to this genre called Panegyric (al-Madih al-Nabawi or al-Madaaih al-Nabawiyya) in a big way.Odes in praise of the Prophet Mohammed(PBUH) are distinct genre of Islamic poetry, which first emerged during his lifetime and have continued after his death in 632. Notable Muslim poets who composed such works during his life include Ka'b ibn Malik, Käb ibn Zuhayr, al-Nabigha al-Jädi, and Abd Allah ibn Rawahah. After the Prophet¿s death, many poets and scholars such as al-Busiri, Shawqi, and others continued to compose panegyric poems.

    Notre étude est important dans la mesure où il traite une période qui a des objectifs lointaine : les conquêtes islamiques qui sont passées par plusieurs étapes dont nous évoquons, à titre d'exemple, la période de la conquête arabe de Barqa.qui grâce à cette conquête, connaît aujourd'hui une grande diversité dans plusieurs domaines comme le domaine culturel qui s'inscrit dans son arabité et son islam intégral. A partir de là, nous pouvons se poser la question sur l'origine de la transformation de la province roumaine en Etat islamique et arabe en quelques siècles seulement La diversité des avis des historiens sur les raisons et les motifs qui ont causé ce changement : un changement qui a influencé l¿islam dans son parcours et la façon dont il a mené la conquête Comment cette région s¿est-elle arabisée et islamisé ? Comment tous ces éléments, par la suite, ont eu un grand impact sur les relations entre le monde musulman et celui chrétien. Comment ce monde latin, à son tour, s'est fait une image irréelle de l'islam et des conquêtes islamiques ? Notre travail se concentrera sur la prospérité économique, et sociale et le grand développement que Barqa a connu .

    Most of orthodontic treatments involve sliding mechanics particularly during overjet reduction or space closure; the major disadvantage with the use of sliding mechanics is the frictional forces resulting from the interaction between the bracket and the guiding archwire, which affect treatment outcomes and duration in a negative way. The aim of the present in vitro study was to evaluate and compare the static and kinetic frictional forces produced by a passive self-ligating bracket and a conventional stainless steel bracket ligated with two different ligation methods under dry condition.
