The power system is growing rapidly in complexity while decision making for systemoperator for such huge system is still a big concern. System real time view is presented tothe operator through the help of several sensors (current transformers, potentialtransformers, bus injection and line power flow meters, and latest introduced phasormeasurement units). Measurement devices can have errors due to telemeter noises andmalfunctioning or could be missing because of accidental isolation of part of powersystem. State estimator filters out these noises and estimates the correct system statevariables (Voltage magnitudes and angles). Since the advancement of smart grid moredata is available and requirement of system’s state estimation accuracy is raised. Relevantresearch is focused on improving the accuracy of estimator in presence of different typeof bad data measurements. Phasor measurement units (PMU) provide complex voltageand current with higher reliability and accuracy improving the performance of stateestimators. This thesis has considered only the availability of complex voltage readingfrom PMU measurements. The impact of incorporating PMU’s on state estimation isinvestigated using three estimators: Weighted Least Square (WLS), IterativelyReweighted Least Square (IRLS), and Least Absolute Value (LAV) using IRLS. Theperformance of incorporating PMU in state estimators is tested under different bad-datascenarios: single, multiple non-interacting, and multiple interacting bad data. Thexviiistandard 6-bus test system will be used for validation purposes. The proposed estimatorwill be then tested on the IEEE 14-bus, IEEE 30-bus systems.

La présence de métaux lourds dans les eaux résiduaires a entraîné une préoccupation environnementale par les scientifiques et les ingénieurs. Un de ces métaux lourds est le cadmium, un métal non essentiels et toxiques pour les êtres vivants. Ce métal a de nombreuses applications dans divers procédés et opérations industriels. Les méthodes classiques d'élimination des métaux à partir des eaux usées sont généralement coûteuses et ont de nombreuses limitations, d'autres méthodes d'élimination des métaux lourds à l'aide de matériaux biologiques ont été considérés. Un certain nombre de micro-organismes comme les bactéries, les champignons, les levures, les Algues et les déchets agricoles, ont été étudiés dans la littérature pour leur capacité à éliminer le cadmium à partir de solutions aqueuses, ces micro-organismes peuvent retenir des quantités relativement élevées de métaux par des procédés passifs connus sous le nom biosorption.

This thesis critically explores Rūḥullāh al-Khumaynī’s (1902–1989) theory of Wilāyat al-Faqīh (guardianship of the jurist), tracing its philosophical sources, and bringing to light its conceptual structure and implications. It presents al-Khumaynī’s argument on the necessity of establishing an Islamic government and his position on the correlation between religious and political authority. It highlights some of al-Khumaynī’s rationales for an Islamic social-critical philosophy and examines his aim in reconciling the relationship between theoretical and practical aspects of Islam. In doing so, it investigates al-Khumaynī’s religio-political vision and the social and political motivations that led him to theorize an Islamic government headed by the guardian jurist, or al-walī al-faqīh. The thesis attempts to answer the question of whether Wilāyat al-Faqīh should be considered as a philosophical, political, or jurisprudential theory.Traditionally, Wilāyat al-Faqīh has been viewed as a legalistic, jurisprudential, and theological notion. However, Wilāyat al-Faqīh can also be understood as a political-philosophical theory that is influenced by a long tradition of Islamic philosophy. I argue that this theory is a legitimate form of Islamic political philosophy. To substantiate this claim, I investigate the philosophical perspective of al-Khumaynī’s religio-political thought and examine the philosophical foundations of Wilāyat al-Faqīh. This entails an analysis of the existing genealogical relationship between Wilāyat al-Faqīh and the philosophical tradition of Islam. Therefore, I discuss how al-Khumaynī’s theory could be seen as a political extension of Mullā Ṣadrā’s (1572–1636) integrative epistemology, despite the fact that no explicit declaration to this effect was made by al-Khumaynī. In this context, I show how theoretical ontology and epistemology turned into practical politics in the hands of al-Khumaynī. I further show how the philosophical characteristics of Wilāyat al-Faqīh reflect the pragmatism of al-Khumaynī who integrated the “idealism” of al-Fārābī (Alpharabius) (870–950/1) and the “realism” of Ibn Sīnā (Avicenna) (980–1037).Through different examples from al-Khumaynī’s texts, I show how al-Khumaynī’s religio-political theory represents a synthesis of three epistemic trajectories: philosophical, mystical, and religious. In particular, I show how it reflects a deep conviction in the subtle concordance between rational and revealed sources of knowledge. Building on a variety of primary and secondary sources, I draw out what al-Khumaynī believes to be the goal of politics in his revolutionary thought and investigate the role of ontology in his religio-political theory. I further situate the philosophical characteristics of al-Khumaynī’s Wilāyat al-Faqīh in relation to its practical implications and political ramifications. In doing so, I locate the structure of the Islamic Revolution and Islamic Republic in contemporary political and philosophical debates. I further discuss al-Khumaynī’s extension of the theory of Wilāyat al-Faqīh in public affairs to the concept of the absolute guardianship of the jurist (al-wilāya al-muṭlaqa li-al-faqīh).The present thesis contributes to an understanding of the connections between Islamic philosophical tradition and al-Khumaynī’s religio-political theory of Wilāyat al-Faqīh. It paves the way for the construction of an original understanding of Islamic political philosophy and argues for its revival in the contemporary world in the hands of al-Khumaynī under what I call a “Transcendent Political Philosophy.”

Customs regulations, customs disputes, which are addressed bynatural and legal persons for the purpose of engaging in activities having a commercialnature in the context of goods movement through the national customs borders is bothentry and exit. The procedures set out in the provisions of the Customs Law are imposedon every goods import and export, and any violation of these procedures is considered as aviolation of legislation and customs regulation themselves, sinceitis the way how anorganized customs-economic crime of a material nature is created.

Le but de ce travail est l’étude d’une bande infinie contenant une fissure de Dugdale parallèle à ces frontières chargée en mode I. En utilisant les transformés de Fourier, les équations du problème élastique sont transformés analytiquement en une équation intégrale singulière de Cauchy du premier type. La résolution de cette équation intégrale se fait numériquement à l’aide des polynômes de Chebychev. A cause de la présence de discontinuités dans la distribution du chargement le long de lèvres de la fissure, les techniques de résolutions classiques ne sont pas applicables et doivent être modifiées. Nous calculons la variation de la contrainte appliquée avec la longueur de la fissure en faisant varier un certain nombre de paramètres du problème. Nous terminons par une comparaison entre les modèles de Dugdale et de Griffith. .

Parmi les éléments de réponse apportés par ce sujet de mémoire, les résultats les plusimportants à retenir restent la validation et la faisabilité du principe de la transductionthermique.A-partir de ces recherches, deux axes devront être améliorés. Le premier concerne laconception. Plusieurs paramètres conditionnent le fonctionnement du capteur, à partir d’unecombinaison entre ces paramètres et le circuit, on peut extraire un schéma électriqueéquivalent, qui permettra d’une part une miniaturisation de l’appareil, d’autre part, uneamélioration de l’interaction entre la chaleur et l’organe de mesure, et ainsi, une améliorationde la sensibilité.Le deuxième axe vise les simulations électriques et thermiques de la structure.L’utilisation de logiciels ISIS a permis une meilleure prise en compte du profil de la réponsethermique.Dans ce projet nous avons donc réussis à mesuré la température et visualisé le changementde cette dernière à laide d'un driver de barre graphes complet associé à des circuits intégrés,tel que le LM35DZ puis nous avons inséré un module de détection fait à partir d’un capteurde température et le LM3914.Enfin, ce projet nous a permis de mettre en oeuvre nos connaissances en électronique,espérons qui soit amélioré par d’autre gent.
