Constructing a Virtual Training Laboratory Using Intelligent Agents

This paper reports on the results and experiences of the Trilogy project; a collaborative project concerned with the development of a virtual research laboratory using intelligence agents. This laboratory is designed to support the training of research students in telecommunications traffic engineering. Training research students involves a number of basic activities. They may seek guidance from, or exchange ideas with, more experienced colleagues. High quality academic papers, books and research reports provide a sound basis for developing and maintaining a good understanding of an area of research. Experimental tools enable new ideas to be evaluated, and hypotheses tested. These three components-collaboration, information and experimentation- are central to any research activity, and a good training environment for research should integrate them in a seamless fashion. To this end, we describe the design and implementation of an agent-based virtual laboratory

‘Hey! Hey! I've seen this one, I've seen this one. It's a classic’: Nostalgia, repeat viewing and cult performance in Back to the Future

This article examines the enduring popularity of Back to the Future (Robert Zemeckis, 1985) and its status as an emergent cult blockbuster for a new generation of fans. It draws on the findings of a small-scale audience survey conducted at a one-off screening of the film at Aberystwyth Arts Centre in early February 2012, where it was part of the University’s cult film club programme. The responses to the survey are contextualised by examples of fan practices found online; these indicate some of the additional ways in which a continued affection for Back to the Future is expressed by its followers. From these sources, two audience-led approaches are developed as a means to investigate on-going fandom of Back to the Future. The first of these is an exploration of the nature and value of fan nostalgia expressed towards Back to the Future and other “classic” popular culture texts of the eighties.2 This includes an examination of the kinds of nostalgia that are articulated by fans towards films that were released before they were born, and takes Barbara Klinger’s work on the practice of re-watching films as a starting point (2006). The second approach considers the popular acting partnership of Michael J. Fox and Christopher Lloyd, and draws on the emergent academic study of cult stardom and performance (Mathijs and Sexton 2011; Egan and Thomas 2013). Through an exploration of these two audience-led approaches, I consider whether it is possible to observe an on-going process of cultification in relation to the Back to the Future franchise in a number of significant ways

Multi-path BGP: motivations and solutions

Although there are many reasons towards the adoption of a multi-path routing paradigm in the Internet, nowadays the required multi-path support is far from universal. It is mostly limited to some domains that rely on IGP features to improve load distribution in their internal infrastructure or some multi-homed parties that base their load balance on traffic engineering. This chapter explains the motivations for a multi-path routing Internet scheme, commenting the existing alternatives and detailing two new proposals. Part of this work has been done within the framework of the Trilogy research and development project, whose main objectives are also commented in the chapter.Part of this work has been done within the framework of the Trilogy research and development project.

Robust P2P Live Streaming

Projecte fet en col.laboració amb la Fundació i2CATThe provisioning of robust real-time communication services (voice, video, etc.) or media contents through the Internet in a distributed manner is an important challenge, which will strongly influence in current and future Internet evolution. Aware of this, we are developing a project named Trilogy leaded by the i2CAT Foundation, which has as main pillar the study, development and evaluation of Peer-to-Peer (P2P) Live streaming architectures for the distribution of high-quality media contents. In this context, this work concretely covers media coding aspects and proposes the use of Multiple Description Coding (MDC) as a flexible solution for providing robust and scalable live streaming over P2P networks. This work describes current state of the art in media coding techniques and P2P streaming architectures, presents the implemented prototype as well as its simulation and validation results

The Cathedral of Being: Re-enchantment and the Writings of the Popes

A rarely discussed issue that bears upon the topic of education is that which takes seriously the relationship between medium and message; how is the content of what is taught shaped by the way in which it is taught? It is a question of especial pertinence today when in all areas of pedagogy we find people advocating the use in education not only of computers but on-line access and the wonders of the virtual world as well. The argument of this paper, via the writings of the recent Pontiffs (and more secular authors with a philosophical and political interest in the area), is that the use of computers and on-line technology is deleterious to all education, but especially to Catholic education. This is because, while the understanding of real presence and mediation are fundamental to the faith, the idea of insubstantiality and friction-free immediacy are of a piece with virtual technology. As a medium of dissemination the latter cannot help but invest the content of the former with its understanding of presence. The paper also touches upon the economic factors at play in the use of virtual technology as well as the utopian hopes this technology gives rise to, hopes that are fundamentally inhuman and therefore at odds with the Catholic faith. The paper argues its point using the trope of fairyland and the opposition between, on the one hand, enchantment, and on the other, glamour

New Era, New Criteria for City Imaging

Despite many dramatic changes in last fifty years, urban designers still try to measure "city imaging" with same criteria as was described by Kevin Lynch in his landmark volumes. However, city imaging increasingly is supplemented by exposure to recent progresses in communication infrastructures. It seems that once again we need to re-ontologize concepts of city imaging for twenty-first century as his ideas were theoretically created when digital evolution was not such widely affected our world. This paper aims to identify effects of these new digital actors on city imaging. Consequently, we propose that with emergence of Softerial Era and infospherization of almost everything, another kind of landmarks have been evolved (linkmarks) which are highly referenced to a self and relative to his destination and necessities in real-time. We believe they can improve not only our “sense of place” but also “sense of time” as an inevitable necessity in our current life.Kevin Lynch, City Imaging, Infospherization, Landmark, Sense of time.

A key issue in this subject is that, although the IP protocol has provided the basis for the rapid evolution of the Internet, its addressing scheme is not prepared to face the challenges posed by many foreseen applications. In light of this, different initiatives worldwide have started specific research programs to address these problems and work toward the "Future Internet". The TARIFA project represents one of these initiatives, and it is positioned as a clean slate alternative aimed at overcoming the critical issues in today's Internet. The novelty in TARIFA resides in the fact that any “commodity” in the network can be composed as a set of atomic services, which can be in turn assembled through a service-centric model for building a promising Internet architecture. In this paper, we focus on the space requirements and set the basis for a new addressing scheme suitable for service-centric network architectures such as the one proposed by TARIFA. The addressing scheme discussed in this paper is general in scope, and could be applied not only to architectures based on the composition of services but also to user and data-centric Internet architectures.This work was supported in part by the TARIFA project, by the Spanish Ministry of Science and Innovation under contract TEC2009-07041, and by the Catalan Research Council (CIRIT) under contract 2009 SGR1508.Postprint (author's final draft
