Available in PDF, EPUB and Kindle. Book excerpt: Avec la croissance continue du trafic aérien et la limitation des ressources, il est nécessaire de réduire la congestion de l'espace aérien. Ces dernières années, un intérêt particulier a été porté au problème de la sectorisation de l'espace aérien.Pour pallier à cette augmentation continue du trafic en Europe, il est nécessaire d'optimiser la gestion du trafic aérien. Une automatisation de la sectorisation de l'espace aérien peut permettre, dans cette optique, d'accroître l'adaptabilité des configurations du secteur aérien à une nouvelle demande de trafic. L'objectif de la première partie de cette thèse est de proposer une méthode globale de sectorisation de l'espace aérien européen en se basant sur une modélisation mathématique et des méthodes d'optimisation heuristiques. La méthode de sectorisation proposée est basée sur la division initiale de l'espace aérien en cellules de Voronoi à l'aide de méthodes des k-moyennes. Pour des raisons de complexité combinatoire induite, un algorithme d'optimisation stochastique est utilisé pour résoudre le problème de sectorisation. Un algorithme génétique est utilisé pour construire les secteurs de l'espace aérien dans plusieurs zones de contrôle européennes, en se basant sur des données réelles de trafic aérien pendant plusieurs jours.De plus, les configurations du secteur de l'espace aérien doivent être adaptées dynamiquement pour offrir une efficacité et une flexibilité maximales en fonction des conditions météorologiques et de circulation. L'objectif de la deuxième partie de cette thèse est d'adapter automatiquement les configurations de l'espace aérien en fonction de l'évolution du trafic, au cours d'une journée de fonctionnement. Pour atteindre cet objectif, il faut considérer que l'espace aérien est divisé en blocs d'espaces aériens 3D qui doivent être groupés ou dégroupés en fonction de l'état du trafic. La méthode proposée est basée sur une technique de partitionnement de graphe et sur des algorithmes génétiques. La méthode est testée sur plusieurs zones de contrôle européennes.

Download or read book Minimisation des conflits aériens par des modulations de vitesse written by David Rey and published by . This book was released on 2012 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Afin de pouvoir subvenir aux futurs besoins en matière de transport aérien il est nécessaire d'augmenter la capacité de l'espace aérien. Les contrôleurs aériens, qui occupent une place centrale dans la gestion du trafic, doivent quotidiennement faire face à des situations conflictuelles (conflits) lors desquelles deux vols risquent de violer les normes de séparation en vigueur si aucune modification de trajectoire n'est envisagée. La détection et la résolution des conflits potentiels contribuent à augmenter la charge de travail des contrôleurs et peuvent potentiellement les conduire à diriger les vols vers des zones moins denses de l'espace aérien, induisant a posteriori un retard pour les vols. Le problème de la capacité de l'espace aérien peut donc être abordé en régulant les flux de trafic de façon réduire la quantité de conflits aériens. L'objectif de cette thèse est de mettre au point une méthodologie destinée à minimiser les risques de conflits aériens en modifiant légèrement les vitesses des appareils. Cette approche est principalement motivée par les conclusions du projet ERASMUS portant sur la régulation de vitesse subliminale. Ce type de régulation a été conçu de façon à ne pas perturber les contrôleurs aériens dans leur tâche. En utilisant de faibles modulations de vitesse, imperceptibles par les contrôleurs aériens, les trajectoires des vols peuvent être modifiées pour minimiser la quantité totale de conflits et ainsi faciliter l'écoulement du trafic dans le réseau aérien. La méthode retenue pour mettre en œuvre ce type de régulation est l'optimisation sous contrainte. Dans cette thèse, nous développons un modèle d'optimisation déterministe pour traiter les conflits à deux avions. Ce modèle est par la suite adapté à la résolution de grandes instances de trafic en formulant le modèle comme un Programme Linéaire en Nombres Entiers. Pour reproduire des conditions de trafic réalistes, nous introduisons une perturbation sur la vitesse des vols, destinée à représenter l'impact de l'incertitude en prévision de trajectoire dans la gestion du trafic aérien. Pour valider notre approche, nous utilisons un outil de simulation capable de rejouer des journées entières de trafic au dessus de l'espace aérien européen. Les principaux résultats de ce travail démontrent les performances du modèle de détection et de résolution de conflits et soulignent la robustesse de la formulation face à l'incertitude en prévision de trajectoire. Enfin, l'impact de notre approche est évalué à travers divers indicateurs propres à la gestion du trafic aérien et valide la méthodologie développée.

Download or read book Faecal Sludge Management written by Linda Strande and published by IWA Publishing. This book was released on 2014-08-15 with total page 428 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is estimated that literally billions of residents in urban and peri-urban areas of Africa, Asia, and Latin America are served by onsite sanitation systems (e.g. various types of latrines and septic tanks). Until recently, the management of faecal sludge from these onsite systems has been grossly neglected, partially as a result of them being considered temporary solutions until sewer-based systems could be implemented. However, the perception of onsite or decentralized sanitation technologies for urban areas is gradually changing, and is increasingly being considered as long-term, sustainable options in urban areas, especially in low- and middle-income countries that lack sewer infrastructures. This is the first book dedicated to faecal sludge management. It compiles the current state of knowledge of the rapidly evolving field of faecal sludge management, and presents an integrated approach that includes technology, management, and planning based on Sandecs 20 years of experience in the field. Faecal Sludge Management: Systems Approach for Implementation and Operation addresses the organization of the entire faecal sludge management service chain, from the collection and transport of sludge, and the current state of knowledge of treatment options, to the final end use or disposal of treated sludge. The book also presents important factors to consider when evaluating and upscaling new treatment technology options. The book is designed for undergraduate and graduate students, and engineers and practitioners in the field who have some basic knowledge of environmental and/or wastewater engineering.

Available in PDF, EPUB and Kindle. Book excerpt: The idea for Philosophy in a Time of Terror was born hours after the attacks on 9/11 and was realized just weeks later when Giovanna Borradori sat down with Jürgen Habermas and Jacques Derrida in New York City, in separate interviews, to evaluate the significance of the most destructive terrorist act ever perpetrated. This book marks an unprecedented encounter between two of the most influential thinkers of our age as here, for the first time, Habermas and Derrida overcome their mutual antagonism and agree to appear side by side. As the two philosophers disassemble and reassemble what we think we know about terrorism, they break from the familiar social and political rhetoric increasingly polarized between good and evil. In this process, we watch two of the greatest intellects of the century at work.

Download or read book Crime and Justice in Late Medieval Italy written by Trevor Dean and published by Cambridge University Press. This book was released on 2007-08-02 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this important study, Trevor Dean examines the history of crime and criminal justice in Italy from the mid-thirteenth to the end of the fifteenth century. The book contains studies of the most frequent types of prosecuted crime such as violence, theft and insult, along with the rarely prosecuted sorcery and sex crimes. Drawing on a diverse and innovative range of sources, including legislation, legal opinions, prosecutions, chronicles and works of fiction, Dean demonstrates how knowledge of the history of criminal justice can illuminate our wider understanding of the Middle Ages. Issues and instruments of criminal justice reflected the structure and operation of state power; they were an essential element in the evolution of cities and they provided raw material for fictions. Furthermore, the study of judicial records provides insight into a wide range of social situations, from domestic violence to the oppression of ethnic minorities.

Available in PDF, EPUB and Kindle. Book excerpt: Long neglected by scholars, medieval and Renaissance Bologna is now recognized as a center of economic, political-constitutional, legal, and intellectual innovation, as the city that served as the cultural crossroads of Italy. The city’s distinctive achievements and its transition from medieval commune to second largest city of the Renaissance Papal State is illuminated by essays that present the work of current historians, many made available in English for the first time, from the broadest possible perspective: from the material city with its porticoes, the conflicts that brought bloodshed and turmoil to its streets, the disputations of masters and students, and to the masterpieces of artists who laid the foundations for Baroque art.

Download or read book Violence and Justice in Bologna written by Sarah Rubin Blanshei and published by Lexington Books. This book was released on 2018-04-02 with total page 301 pages. Available in PDF, EPUB and Kindle. Book excerpt: This collection of essays offers a unique contribution to the study of violence and justice in a late medieval and early modern Italy by combining a multivocal perspective with a case-study focus on the city-state of Bologna. Drawing on the city’s singularly rich archival resources, the authors explore various facets of violence—ranging from the interpersonal to the less frequently studied typologies of blasphemy, rape, political rebellion, and student brawls—and set the institutions of the police and law courts into their socio-political and cultural contexts. They also apply a broad variety of quantitative and qualitative approaches—processual, microhistorical, legalism, comparative and criminological—to their assessments of the procedures and practices of criminal justice and the experiences of violent behavior, providing both short-term, in-depth analyses of specific events and over-arching reviews of long-term trends. Bologna itself, with its renowned university, economic innovations, strategic importance as a commercial and cultural crossroads, its political volatility and experiments with diverse constitutional structures, provides a rewarding laboratory for analyzing changes and continuities in late medieval and early modern violence and justice. From these studies emerges a narrative that challenges the traditional portrayal of those periods as eras when brutality and rage were “normal” in social relations and criminal justice was characterized mainly by punitive strategies of torture and repression.
