Assessment of a Fuel Cell Powered Air Taxi in Urban Flight Conditions
Assessment of a Fuel Cell Powered Air Taxi in Urban Flight Conditions M. Husemann1, C. Glaser2, E. Stumpf3 Institute of Aerospace Systems (ILR), RWTH Aachen University, 52062 Aachen, Germany This paper presents a first estimation of potential impacts on the flight operations of small air taxis in urban areas using a fuel cell instead of a battery as an energy resource. The expanding application of electric components is seen as a possibility to reduce operating costs and environmental impacts in the form of noise and pollutant emissions due to lower consumption of fossil fuels. The majority of such designs have so far been based on the use of (not yet) sufficiently efficient batteries. Long charging times, possible overheating or a limited service life in the form of limited charging cycles pose a challenge to the development of such aircraft. Parameter studies are conducted to identify possible advantages of using a fuel cell. In particular, the range and payload capacity ist investigated and first effects on the cost structure will be presented. The evaluation of the studies shows that the use of fuel cells enables significantly longer ranges than the use of batteries. In addition, the range potential gained can be used, for example, to transport more payload over the same distance. Furthermore, the technological maturity in the form of the individual energy density and the weight of the powertrain unit has a significant effect on the cost structure. Fuel cells therefore have a high potential for applications in the mobility sector, but still require extensive research efforts. I. Introduction Increasing traffic volume due to advanced technologies and growing mobility demand often leads to heavy traffic and circumstantial routing, especially in metropolitan areas. -
The Right to Privacy and the Future of Mass Surveillance’
‘The Right to Privacy and the Future of Mass Surveillance’ ABSTRACT This article considers the feasibility of the adoption by the Council of Europe Member States of a multilateral binding treaty, called the Intelligence Codex (the Codex), aimed at regulating the working methods of state intelligence agencies. The Codex is the result of deep concerns about mass surveillance practices conducted by the United States’ National Security Agency (NSA) and the United Kingdom Government Communications Headquarters (GCHQ). The article explores the reasons for such a treaty. To that end, it identifies the discriminatory nature of the United States’ and the United Kingdom’s domestic legislation, pursuant to which foreign cyber surveillance programmes are operated, which reinforces the need to broaden the scope of extraterritorial application of the human rights treaties. Furthermore, it demonstrates that the US and UK foreign mass surveillance se practices interferes with the right to privacy of communications and cannot be justified under Article 17 ICCPR and Article 8 ECHR. As mass surveillance seems set to continue unabated, the article supports the calls from the Council of Europe to ban cyber espionage and mass untargeted cyber surveillance. The response to the proposal of a legally binding Intelligence Codexhard law solution to mass surveillance problem from the 47 Council of Europe governments has been so far muted, however a soft law option may be a viable way forward. Key Words: privacy, cyber surveillance, non-discrimination, Intelligence Codex, soft law. Introduction Peacetime espionage is by no means a new phenomenon in international relations.1 It has always been a prevalent method of gathering intelligence from afar, including through electronic means.2 However, foreign cyber surveillance on the scale revealed by Edward Snowden performed by the United States National Security Agency (NSA), the United Kingdom Government Communications Headquarters (GCHQ) and their Five Eyes partners3 1 Geoffrey B. -

Dystopian RevolutionBy MikeI enjoyed this dystopian novel. Fans of dystopian novels, such as George Orwell's 1984, and ardent Frank Herbert fans will probably enjoy this novel. Those looking for a new Frank Herbert sci-fi novel, similar to Dune or The Dosadi Experiment, might want to think twice before getting this book.Setting is the near future where the world has become dominated by opinion polls and those who control the polls. In theory, those who rule are freely elected but in practice control has accumulated into the hand of a few families and their governmental bureaus. Frank Herbert goes onto explore how societies and governments have cycles and are destined to fail and how the actions of individuals and societies can be predicted scientifically. Daniel Movius has rose rapidly in the system which purportedly allows all to succeed but he falls even more rapidly as a result of political machinations. Daniel then goes on to join the separatist movement and turbocharge their languishing revolution. Overall, this is a good story which is filled with suspense, intrigue and action.I would be interested to know when this novella was written in relation to some of Frank Herbert's other novels - unfortunately I could not find this information. -

U.S. NEWS New Details Show Broader NSA Surveillance Reach Programs Cover 75% of Nation's Traffic, Can Snare Emails By SIOBHAN GORMAN and JENNIFER VALENTINO-DEVRIES Updated Aug. 20, 2013 11:31 p.m. ET WASHINGTON—The National Security Agency—which possesses only limited legal authority to spy on U.S. citizens—has built a surveillance network that covers more Americans' Internet communications than officials have publicly disclosed, current and former officials say. The system has the capacity to reach roughly 75% of all U.S. Internet traffic in the hunt for foreign intelligence, including a wide array of communications by foreigners and Americans. In some cases, it retains the written content of emails sent between citizens within the U.S. and also filters domestic phone calls made with Internet technology, these people say. The NSA's filtering, carried out with telecom companies, is designed to look for communications that either originate or end abroad, or are entirely foreign but happen to be passing through the U.S. -

Treball Final De Grau
TREBALL FINAL DE GRAU TÍTOL DEL TFG: Air taxi transportation infrastructures in Barcelona TITULACIÓ: Grau en Enginyeria d’Aeronavegació AUTOR: Alexandru Nicorici Ionut DIRECTOR: José Antonio Castán Ponz DATA: 19 de juny del 2020 Títol: Air taxi transportation infrastructures in Barcelona Autor: Alexandru Nicorici Ionut Director: José Antonio Castán Ponz Data: 19 de juny del 2020 Resum El següent projecte parteix de la visió d’un futur on la mobilitat urbana es reparteix també al medi aèri. A partir d’aquesta premissa, s’escull el dron de passatgers com a mitjà de transport i es busca adaptar tot un sistema infrastructural per al vehicle autònom dins el perímetre d’una ciutat, Barcelona. En un inici, la primera pregunta a respondre és: permet la normativa actual l’ús de drons de passatgers autònoms en zones urbanes? Tant les regulacions europees com les nacionals espanyoles han estat estudiades i resumides per determinar que sí es permeten operacions amb aquest tipus de vehicles i es preveu la seva integració dintre de l’aviació civil. Seguidament, un estudi de mercat de taxi drons és realitzat amb l’objectiu d’esbrinar si la tecnologia d’avui dia permet operar a paràmetres òptims i oferir el servei de taxi d’una manera completament segura i satisfactòria per al client. Prototips en fase de test i actualment funcionals han estat analitzats; per finalment, elegir un d’aquest últims com a candidat apte per al transport de persones dins la capital catalana. Un cop es té el vehicle de transport, cal mirar si la pròpia ciutat ofereix garanties d’èxit per aquest servei de transport aeri. -

That means reviewing the authorities of law enforcement, so we can intercept new types of communication, but also build in privacy protections to prevent abuse´ --President Obama, May 23, 2013 In his May 2013 address at the National Defense University, the President made clear that we, as a Government, need to review the surveillance authorities used by our law enforcement and intelligence community professionals so that we can collect information needed to keep us safe and ensure that we are undertaking the right kinds of privacy protections to prevent abuse. In the wake of recent unauthorized disclosures about some of our key intelligence collection programs, President Obama has directed that as much information as possible be made public, while mindful of the need to protect sources, methods and national security. Acting under that guidance, the Administration has provided enhanced transparency on, and engaged in robust public discussion about, key intelligence collection programs undertaken by the National Security Agency (NSA). This is important not only to foster the kind of debate the President has called for, but to correct inaccuracies that have appeared in the media and elsewhere. This document is a step in that process, and is aimed at providing a VXFFLQFWGHVFULSWLRQRI16$¶V mission, authorities, oversight and partnerships.
