Available in PDF, EPUB and Kindle. Book excerpt: Un grand nombre de véhicules de mobilité aérienne urbaine, en anglais Urban Air Mobility (UAM), devraient opérer dans l'espace aérien urbain dans un avenir proche. Cette croissance dépassera bientôt les capacités de l'espace aérien et des systèmes de gestion du trafic aérien actuels et mettra à rude épreuve les infrastructures de transport, entraînant des résultats indésirables tels que des encombrements, des situations de trafic complexes, des retards, etc. Par conséquent, des solutions UAM innovantes sont nécessaires pour garantir un transport urbain sûr et efficace. Dans cette thèse, nous nous concentrons sur la planification stratégique du trafic des drones, y compris l'organisation ainsi que la gestion de l'espace aérien et des flux de trafic. Plus précisément, nous développons des approches pour la conception du réseau de routes UAM et l'affectation du trafic aérien associé. Afin de minimiser l'impact sur les systèmes de gestion du trafic aérien existants, cette thèse propose une méthodologie pour concevoir un réseau de routes UAM dans l'espace aérien urbain à basse altitude en présence d'obstacles et d'espaces aériens dangereux. Sur la base de diverses données publiques, cette approche a été appliquée à l'espace aérien urbain de Singapour comme cas d'étude pour les services de livraison de colis utilisant des UAVs. Dans un premier temps, le réseau de routes UAM est conçu à partir de grilles qui évitent les obstacles et les zones interdites. Ensuite, les coûts d'arcs sont définis en termes d'impact sonore sur les populations, de sécurité de l'espace aérien et d'efficacité du vol. Nous formulons un problème de k-plus courts chemins avec diversité pour sélectionner les routes réalisables qui minimisent le coût associé. Les itinéraires réalisables avec une faible similarité fourniront plus d'options de trajet, qui peuvent être utilisées pour générer le réseau de routes UAM afin de prendre en charge les opérations à haute densité et à flux complexe. En outre, l'impact de différents paramètres pour les coûts d'arcs sur les services UAM est également analysé. Bien que la méthodologie proposée soit appliquée à l'espace aérien urbain de Singapour, elle pourrait facilement être généralisée à d'autres espaces aériens urbains dans le monde. Pour adapter la demande croissante à la capacité actuelle de l'espace aérien, nous avons proposé plusieurs modèles d'affectation du trafic aérien, notamment deux modèles statiques pour les réseaux de routes UAM à une et à plusieurs couches et un modèle dynamique pour les réseaux de routes UAM birectionnels multicouches, afin d'atténuer la congestion et la complexité et d'organiser la structure du flux de trafic aérien. Premièrement, au niveau macroscopique, les opérations UAM sont modélisées sous forme de flux de trafic en agrégeant la dynamique des véhicules individuels. Les flux sont répartis sur des réseaux de routes UAM, pour lesquels les routes aériennes sont modélisées comme des couloirs ou des segments volumétriques. Ensuite, le modèle d'affectation du trafic aérien est formulé comme un problème d'optimisation. Les critères sont modélisées de manière à décrire la complexité et la congestion du trafic aérien sur la base d'un système dynamique linéaire. Un cadre basé sur la simulation, comprenant différentes approches d'optimisation, est proposé pour résoudre efficacement ces problèmes. Des expériences informatiques sont réalisées sur des études de cas de réseaux de routes UAM à différentes échelles. Une comparaison avec les algorithmes conventionnels d'affectation du trafic est présentée. Les résultats montrent que l'approche proposée est capable d'affecter les flux de manière efficace et efficiente, en réduisant de manière significative la complexité du réseau de routes UAM 3D. Le modèle proposé peut être utilisé pour aider les régulateurs et les fournisseurs de service de navigation aérienne pour l'affectation du trafic aérien dans la planification stratégique des opérations UAM.

Book excerpt: While the military use of drones has been the subject of much scrutiny, the use of drones for humanitarian purposes has so far received little attention. As the starting point for this study, it is argued that the prospect of using drones for humanitarian and other life-saving activities has produced an alternative discourse on drones, dedicated to developing and publicizing the endless possibilities that drones have for "doing good". Furthermore, it is suggested that the Good Drone narrative has been appropriated back into the drone warfare discourse, as a strategy to make war "more human". This book explores the role of the Good Drone as an organizing narrative for political projects, technology development and humanitarian action. Its contribution to the debate is to take stock of the multiple logics and rationales according to which drones are "good", with a primary objective to initiate a critical conversation about the political currency of "good". This study recognizes the many possibilities for the use of drones and takes these possibilities seriously by critically examining the difference the drones' functionalities can make, but also what difference the presence of drones themselves – as unmanned and flying objects – make. Discussed and analysed are the implications for the drone industry, user communities, and the areas of crisis where drones are deployed.

The study offers an assessment of key issues influencing the evolution of air power in continental Europe. Amongst the main challenges are deployed operations, the intellectual grasp of air power doctrine, and the imbalance between combat aircraft and force enablers. Regarding the latter, the development of common capabilities that are equally available to both NATO and the European Union is crucial."--P. [4] of cover.

Available in PDF, EPUB and Kindle. Book excerpt: Acronym agglomeration is an affliction of the age, and there are acronym addicts who, in their weakness, find it impossible to resist them. More than once in recent months my peers have cautioned me about my apparent readiness to use not only acronyms, but abbreviations, foreign isms, codes, and other cryptic symbols rather than common, ordinary American words. Many among us, though, either have not received or have chosen to ignore such advice. As a consequence, what we write and speak is full of mystery and confusion. It is then for the reader and listener and for the writer and speaker that Reta C. Moser has compiled this guide. Its effective application to the art of communication is urged. Such use should help avoid many of the misunderstandings involving terminology which occur daily. Although such misunderstandings are certainly crucial in humanistic and social situations, they are often of immediate import and the trigger to disaster in scientific, technical, and political situations. Some 15,000 acronyms and 25,000 definitions are provided (a 50- and 47 -percent increase over the 1964 edition!), with due credit to Miss Moser's diligence in making the compilation and with the acknowledgment that the acronymical phenomenon is very much with us. This edition, like the first, is certain to be of value to writers, librarians, editors, and others who must identify and deal with acronyms.

Book excerpt: Defending Europe seeks to clarify the competing ambitions, the contrasting visions and the trans-Atlantic tensions related to the recent quest by Europe for autonomy in the sphere of security and defense. Scholars from both sides of the Atlantic explore the development of ESDI within NATO, the revival of the WEU and the launch of the EU's Common European Security and Defense Policy. Among the issues discussed are the Euro-American capabilities gap, concerns regarding decoupling, discrimination, and duplication, and the complications posed by NATO/EU enlargement. Two contrary conclusions debate whether ESDP is more likely to strengthen or undermine the Atlantic Alliance. This informative foray into the trans-Atlantic security and defense issues is a crucial addition to the ongoing dialogue concerning this shifting and evolving relationship.

Kania and published by Createspace Independent Publishing Platform. This book was released on 2018-08-10 with total page 38 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Chinese People's Liberation Army (PLA) continues to work diligently on all aspects of their aerospace forces. This includes areas not only of traditional aircraft, but also in more modern, and some cutting edge, technologies. The UAV is one area in which the People's Republic of China, and the PLA in specific, has invested significant time and effort. While we recognize that the term "unmanned" is the common and official term, it is rather misleading in the fact that humans, at least up until today, still play a critical role in their operations. Nonetheless, we will not buck convention at this moment, and continue to use "unmanned" for the 'U' in UAV, for this paper. The PRC is the world's largest producer of UAVs at this time, and captures a vast portion of the commercial market, as well as the military one. While it is important to keep the commercial aspects in mind, this particular paper will focus on military UAVs, their development, deployments, and current and potential uses on the battlefield of today and tomorrow. The paper seeks to serve as a starting point to understand this growing field, and to give analysts a common baseline from which to work, and from which to judge growth, both rapidity and complexity, in the future.
