Composite Wing

THE ATR consortium manufactures a range of transport aircraft for which Aerospatiale supplies the wings and associated structure and Alenia of Italy manufactures the fuselage and empennage. Engines, propellers and landing gear are supplied by Pratt & Whitney of Canada, Hamilton Standard and Messier‐Bugatti, respectively. At Le Bourget this year, the opportunity was taken to introduce new models together with plans for the future.

Debris Impact

AbstractLarge transport aircraft are particularly susceptible to impact damage from runway debris thrown up by the landing gear. A methodology was developed to predict the trajectories of stones lofted by the nose wheel and subjected to aerodynamic forces due to the wake behind the nose landing gear and beneath the aircraft. In conjunction with finite element modelling of the stone/ground/tyre contact mechanics, an analytical model was used to perform a stochastic prediction of the trajectories of runway stones to generate impact threat maps which showed the relative likelihood of stones impinging upon various areas on the underside of a C-130 Hercules. The impact envelopes for the C-130 extended three to eighteen metres behind the nose wheel and two metres either side of the centre of the aircraft. The impact threat maps were especially sensitive to the values of the coefficients of lift and drag acting on the stone during its flight.

Representation Of Time

Es tiempo para reflexionar sobre las consecuencias que, para el pensamiento historiográfico, significan los nuevos modos de representación simbólica del tiempo relacionados con los cambios materiales e intelectuales de fin de siglo. Los viejos paradigmas positivistas y estructuralistas, de naturaleza moderna (racionalidad, explicación, objetividad, linealidad, teleología, necesidad, normativismo, universalidad), van dando paso a nuevos modelos de construcción del relato histórico según patrones fenomenológico-hermenéuticos (interpretación, ruptura, azar, relativismo, localismo). La crisis de la idea ilustrada de progreso está impulsando una nueva concepción "anti-histórica», en la medida en que la historia se convierte en espacio temporal pluridimensional, ambiguo, efímero, atemporal. El nuevo tiempo de la historia deja de ser proyectivo. ¿No estaremos ante la elaboración simbólica de una experiencia vital verdaderamente ahistóríca? ¿Qué puede representar ello en lo que respecta al cambio social? ¿Paralización? ¿Congelación y perpetuación del nuevo orden? ¿Es posible ya la anticipación del futuro desde un presente desligado de toda secuencia racionalmente inteligible para el sujeto?.It's time to think about the consequences which, to the historiographic though, mean the new ways of symbolic representation of time related to the material and intelectual changes at the end of this century. The old positivist and structuralist paradigms, of modern nature (rationality, explanation, objectivity, lineality, teleology, necessity, universality), are giving way to the new models of construction of the historical discourse following phenomenological-hermeneutical patterns (interpretation, rupture, chance, relativism, localism). The crisis of the enlightened idea of progress is urging a new non-historie conception, as for as history turns inte temporal space which is also multi-dimensional, ambiguous, ephemeral, nontemporal. The new time of history is no longer projecting to the future. Isn´t it possible we are facing a symbolic elaboratlon of a vital experience which is truely nonhistorie? What can it represent in the social change? Can it be paralysation? Can it be freezing and perpetuation of a new order? Is it already possible the anticipation of the future from a present which is detached from any sequence rationaly understandable to the subject?

Traditional news outlets are on the decline and journalism has embraced digital media in its struggle to survive. New models of delivering news to the public are being explored in order to increase the levels of readership and user engagement.The narrative of this chapter focuses on the future of journalism and media, and the potential benefits and dangers of gamifying journalism. Since gamification is a new trend, a thorough look at the intersection between the enhancements of public mobility, the digitalization of news services, and the engagement of gamified systems can bring better understanding of future channels of reading news to the users, to researchers, and to the industry. This chapter aims to bridge the gap between gamification as an emerging practice in news distribution and yet a vastly uncharted area or research.

This chapter resumes the accordion's history at around the year 1963, after the accordion had reached the height of its popularity and America's youth were beginning to embrace new music and new instruments. Looking at the accordion in the context of the rock 'n' roll invasion and the rise of youth culture, this chapter examines the accordion industrial complex's efforts to extend its popularity—focusing on a trickle of new models equipped with features for rock accordionists. Yet the chapter also shows how this new sense of excitement about the future of the accordion subsided and how playing the accordion became, for all intents and purposes, geeky and uncool.

Libraries exist because people make decisions and take actions based on a framework of practice that is informed by theory and experience. Research in the library world can build on any or all of these elements: understanding former and existing practices, identifying potential new models for our work, engaging with conceptual models from other disciplines and arenas, or articulating a vision for the future that matches the values we hold today.
