Establishing a healthy lifestyle has become a very important aspect in people’s lives. The latter requires maintaining a healthy nutrition by considering the nature and quantity of foods being consumed, as well as maintaining an active lifestyle including the necessary amount of physical exercise to regulate one’s intake and consumption of calories and nutrients. As a result, people reach out for nutrition experts which entails various obstacles: (i) the cost of seeking an expert’s help which is recurring and non-trivial, (ii) the time commitment required from a person to attend regular meetings with the expert, and (iii) the need for readily accessible health services which might be difficult to provide by a human expert. In this master thesis study, we design, implement, and evaluate a novel framework titled PIN: a computerized solution for Personalized Intelligent Nutrition recommendations. PIN consists of four main modules allowing four essential complementary functionalities: (i) Weight Assessment and Recommendation (WAR), (ii) Caloric Intake and Exercise Recommendation (CIER), (iii) Progress Evaluation and Recommendation Adjustment (PERA), and (iv) personalized Meal Plan Generation (MPG) and adaptation following patient chosen parameters (e.g., food preference, food compatibility, price, etc.). While most existing computerized solutions focus solely on the meal plan generation task, PIN provides the first full-fledged solution for nutrition health assessment, which results are required to run the meal planning task. It relies on the fuzzy logic paradigm to simulate human expert health assessment including weight, caloric intake, and exercise recommendations as well as progress evaluation and recommendation adjustments. PIN also provides a novel contribution in meal planning, introducing an adaptation of the transportation optimization problem to dynamically generate, change, adapt, and self-evaluate meal plans following the patient’s needs, compared with most existing meal planning solutions which fail to integrate all the different essential factors (meal-food compatibility, inner-food compatibility, preferences, diversity, and variety) while producing meal plans. We have conducted a large battery of experiments involving 50 patient profiles, 11 nutrition expert evaluators, and 5 non-expert testers, to test the performance of PIN, evaluating its health assessment and meal plan generation quality. Results highlight PIN’s assessment and recommendation qualities which are on a par with and sometimes surpass those of human nutrition experts.

Le travail présenté dans ce mémoire porte sur l’étude et la simulation d’un filtre actif parallèlemultiniveaux, comme une solution de dépollution des réseaux électriques.Avant d’aller au cœur de notre objectif, au premier chapitre nous avons présenté lesdifférentes sources de pollution des réseaux électriques, leurs conséquences sur le réseau et lesdifférentes méthodes de dépollution proposées dans la littérature (moderne et traditionnelle).Nous avons consacré le deuxième chapitre à l’étude du filtre actif parallèle deux niveaux, ou laméthode de la puissance active et réactives instantané est utilisée pour identifier les courantsperturbateurs. En fin, nous avons présenté les résultats de simulation obtenus sous le logicielMatlab /Simulink, qui montrent que notre filtre compense les perturbations générées par la chargenon linéaire, le courant contient moins d’harmoniques (THD de 22.11% à 4.34%).Au troisième chapitre, nous avons voulu élargir le domaine d’application des filtres actifsparallèles du simple niveau à un niveau multiple. Nous avons d’abord commencé par l’introductiondes différentes topologies d’onduleurs multiniveaux et leurs structures, nous avons opté pourl’onduleur NPC à trois niveaux commandé par MLI sinusoïdale. Les résultats de simulationmontrent une diminution de taux de distorsion (THD de 4.34% à 3.24%) par rapport à la premièresimulation et le courant devient de plus en plus proche de la sinusoïde.On conclut d’après les résultats de la simulation obtenue qu’à chaque augmentation du nombredu niveau de tension du l’onduleur, les harmonique du réseau alternatif se réduisent d’une manièreefficace, ce qui permet de réduire la valeur de l’inductance du filtre de sortie de l’onduleur.Comme perspectives pour les futures promotions on peut citer: La réalisation pratique du travail réalisé en simulation. Utilisation de nouvelles commandes plus évoluées à notre système. Considération d’autres types de perturbation tels que : creux de tension,déséquilibre,…etc

Prostate cancer, the most common non-cutaneous cancer among men worldwide, remains the second leading cause of death among male cancer patients. Despite its curability with castration, radiation and hormonal therapy, some patients develop metastatic disease and die. Initially, prostate cancer cell growth depends on androgens and androgen receptor (AR) signaling, however it often becomes androgen-independent, a state called castration-resistant prostate cancer (CRPC). This later form of prostate cancer is lethal and metastasizes to secondary distant organs. The limited therapeutic options, in addition to acquired-resistance to existing and new anti-androgen and anti-AR drugs, have paved the way for a new generation of treatments for CRPC. Retinoids are vitamin A derivatives and synthetic analogs, which regulate crucial biological processes such as cellular proliferation, apoptosis, and differentiation. Therefore, retinoids have been used successfully in the treatment and prevention of solid and liquid tumors. However, the use of natural retinoids as anti-cancer agents is restricted by their toxicity and acquired resistance. As a result, synthetic retinoids were developed with reduced toxicity and increased specificity, namely the atypical adamantyl retinoid ST1926 which has increased bioavailability and reduced toxicity.We were interested in testing the anti-tumor properties and mechanism of action of ST1926 in prostate cancer using well-characterized human prostate cancer lines, namely DU145 and PC3. We have shown, using 2D conventional models, a significant reduction in cell viability and inhibition of proliferation in both cell lines upon treatment with pharmacologically achievable micromolar (μM) concentrations of ST1926. ST1926-induced cell death was through apoptosis, as it was evident by the accumulation of treated cells in the pre-G1 region of the cell cycle, TUNEL positivity, and PARP cleavage. Moreover, 1 μM ST1926 induced a major upregulation in the expression levels of the sensit

Regarding the complex relationship that relates between language and culture, specifically the relationof culture to language learning, the present research is concerned with identifying the core objective beyond including culture in foreign language teaching, and the role it plays in facilitating language learning and understanding process. It is common for language learning to primarily be based on mastery of four major competences: listening, speaking, reading, and writing for the purpose of ensuring a better communication. In this regard, the present study is conducted under the object of revealing the place culture occupies in language learning, as well as highlighting its effectiveness. Differently put, this study is conducted for the core objective of investigating whether teachers consider culture as the fifth skill, the ways culture affects the language learning skills, and whether teachers include it in teaching the skills. In the present research we opted for two instruments: the questionnaire and the interview for both quantitative and qualitative data collection, administered to ten (10) high school English teachers to accomplish and examine the research issue. The obtained results showcase the importance of culture toward language learning in the Algerian system of education, and demonstrate that culture is not considered as the fifth skill; however, it is integrated with the four skills.
