Building a Stronger Eastern Partnership: Towards an EaP 2.0
The European Union has been working to deepen the economic and political relationship with its Eastern neighbouring countries over the recent years. A set of formal agreements are intended for signature between the EU and Ukraine, Moldova and the South Caucasus states at the Eastern Partnership (EaP) summit scheduled for 28-29 November 2013. These agreements have provoked a response from the Russian Federation which is seeking to offer an alternative set of economic relationship to the exclusion of the EU.
In the first Policy Paper to be published, the recently created Global Europe Centre (GEC) sets out a reform agenda that the EU needs to adopt towards the EaP states to enable a more binding relationship. The paper argues that the EU needs to define a ânext generationâ objective for the EaPas it enters the implementation phase of the current set of Association Agreements (AAs). The proposal is that the EU should set a European Partnership Community (EPC) statusas a bilateral and multilateral goal for the EaP. The paper contends that there is urgency for the EU to think more strategically vis-Ă -vis its neighbourhood, and create a more clear-cut place for Russia to avoid the current situation of divisive competition.
Further, the EU needs to reform aspects of its current EaP policy. The EU needs to define a clearer, and measureable set of objectives for its role in the resolution of the âfrozenâ conflicts of its Eastern neighbourhood; refresh its policy towards Belarus; speed up visa liberalisation to ease travel for citizens of the EUâs neighbouring states; and deepen and broaden civil society engagement by investing more in deep democracy, linkage and people-to-people contacts
Soft or hard Brexit? EPC Commentary, 15 July 2016
The EU is in uncharted waters when it comes to negotiating the UKâs exit from the Union. Creative and flexible thinking will be required from all parties if an orderly departure is to be managed. The alternative is a fractious, mutually damaging and disorderly Brexit. This commentary argues for a short-term, time-limited agreement to stabilise the EU-UK relationship and to allow breathing space to develop the terms of a long-term strategic partnership
Space Shuttle Orbiter And Subsystems
Considerable progress has been made in designing the Space Shuttle orbiter and defining its subsystems since the development contract was awarded by NASA to Rockwell International in August, 1972. During the past two years, NASA and Rockwell International, Space Division have been engaged in an intensive effort to refine orbiter preliminary design concepts and to translate them into reality. This paper describes the orbiter \u27s configuration and its major subsystems. The general arrangement of the vehicle and its major assemblies are described. Orbiter flight characteristics and mission profiles are summarized. Selected subsystems including structure, thermal protection, propulsion, power, reaction control, orbital maneuvering, environmental control and life support, hydraulics, avionics, and accommodations for crew and payloads are described
Brexit or Bremain: What future for the UKâs European Diplomatic Strategy?
A major public debate on the costs and benefits of the United Kingdomâs membership of the European Union is presently under way. The outcome of the referendum on 23 June 2016 will be a pivotal moment in determining whether the EU has a future as a component of the UKâs European diplomatic strategy or whether there is a major recalibration of how the UK relates to Europe and more widely of its role within international relations. Since accession to the European Economic Community the UK has evolved an uncodified, multipronged European diplomatic strategy. This has involved the UK seeking to reinforce its approach of shaping the security of the continent, preserving a leading diplomatic role for the UK in managing the international relations of Europe, and to maximize British trade and investment opportunities through a broadening and deepening of Europe as an economically liberal part of the global political economy. Since accession the UKâs European diplomatic strategy has also been to use membership of the EU as facilitating the enhancement of its international influence, primarily as a vehicle for leveraging and amplifying broader national foreign and security policy objectives. The strategy has been consistent irrespective of which party has formed the government in the UK. Increasing domestic political difficulties with the process of European integration have now directly impacted on this European strategy with a referendum commitment. Whether a vote for a Brexit or a Bremain, the UK will be confronted with challenges for its future European strategy
Mechanization of and experience with a triplex fly-by-wire backup control system
A redundant three axis analog control system was designed and developed to back up a digital fly by wire control system for an F-8C airplane. The mechanization and operational experience with the backup control system, the problems involved in synchronizing it with the primary system, and the reliability of the system are discussed. The backup control system was dissimilar to the primary system, and it provided satisfactory handling through the flight envelope evaluated. Limited flight tests of a variety of control tasks showed that control was also satisfactory when the backup control system was controlled by a minimum displacement (force) side stick. The operational reliability of the F-8 digital fly by wire control system was satisfactory, with no unintentional downmodes to the backup control system in flight. The ground and flight reliability of the system's components is discussed
Mechanization of and experience with a triplex fly-by-wire backup control system
A redundant three-axis analog control system was designed and developed to back up a digital fly-by-wire control system for an F-8C airplane. Forty-two flights, involving 58 hours of flight time, were flown by six pilots. The mechanization and operational experience with the backup control system, the problems involved in synchronizing it with the primary system, and the reliability of the system are discussed. The backup control system was dissimilar to the primary system, and it provided satisfactory handling through the flight envelope evaluated. Limited flight tests of a variety of control tasks showed that control was also satisfactory when the backup control system was controlled by a minimum-displacement (force) side stick. The operational reliability of the F-8 digital fly-by-wire control system was satisfactory, with no unintentional downmodes to the backup control system in flight.

Comet nongravitational forces and meteoritic impacts
We have considered those comets whose original orbits have been determined to be hyperbolic when only planetary perturbations are accounted for. It is found that formally unbound incident trajectories correlate most confidently with orbits that have small perihelion distances and move in a retrograde sense relative to planetary motion. Arguments are presented that these results are not due to measurement error or to selection effects. We conclude that the phenomenon is attributable to enhanced volatility leading to abnormally large nongravitational forces. Since the effect is absent in the prograde small-perihelia population, increased insolation is not the sole explanation. It is suggested that the significance of the retrograde correlation is connected with a larger energy of relative motion between retrograde comets and a population of prograde ecliptic meteoroids which impact the comet mantle exposing the underlying volatiles. The subsequent enhanced outgassing is the cause of the larger nongravitational forces
