Proceedings of the Third Edition of the Annual Conference on Wireless On-demand Network Systems and Services (WONS 2006)

Ce fichier regroupe en un seul documents l'ensemble des articles accéptés pour la conférences WONS2006/http://citi.insa-lyon.fr/wons2006/index.htmlThis year, 56 papers were submitted. From the Open Call submissions we accepted 16 papers as full papers (up to 12 pages) and 8 papers as short papers (up to 6 pages). All the accepted papers will be presented orally in the Workshop sessions. More precisely, the selected papers have been organized in 7 session: Channel access and scheduling, Energy-aware Protocols, QoS in Mobile Ad-Hoc networks, Multihop Performance Issues, Wireless Internet, Applications and finally Security Issues. The papers (and authors) come from all parts of the world, confirming the international stature of this Workshop. The majority of the contributions are from Europe (France, Germany, Greece, Italy, Netherlands, Norway, Switzerland, UK). However, a significant number is from Australia, Brazil, Canada, Iran, Korea and USA. The proceedings also include two invited papers. We take this opportunity to thank all the authors who submitted their papers to WONS 2006. You helped make this event again a success

Using MapReduce Streaming for Distributed Life Simulation on the Cloud

Distributed software simulations are indispensable in the study of large-scale life models but often require the use of technically complex lower-level distributed computing frameworks, such as MPI. We propose to overcome the complexity challenge by applying the emerging MapReduce (MR) model to distributed life simulations and by running such simulations on the cloud. Technically, we design optimized MR streaming algorithms for discrete and continuous versions of Conway’s life according to a general MR streaming pattern. We chose life because it is simple enough as a testbed for MR’s applicability to a-life simulations and general enough to make our results applicable to various lattice-based a-life models. We implement and empirically evaluate our algorithms’ performance on Amazon’s Elastic MR cloud. Our experiments demonstrate that a single MR optimization technique called strip partitioning can reduce the execution time of continuous life simulations by 64%. To the best of our knowledge, we are the first to propose and evaluate MR streaming algorithms for lattice-based simulations. Our algorithms can serve as prototypes in the development of novel MR simulation algorithms for large-scale lattice-based a-life models.https://digitalcommons.chapman.edu/scs_books/1014/thumbnail.jp

Pseudo-contractions as Gentle Repairs

Updating a knowledge base to remove an unwanted consequence is a challenging task. Some of the original sentences must be either deleted or weakened in such a way that the sentence to be removed is no longer entailed by the resulting set. On the other hand, it is desirable that the existing knowledge be preserved as much as possible, minimising the loss of information. Several approaches to this problem can be found in the literature. In particular, when the knowledge is represented by an ontology, two different families of frameworks have been developed in the literature in the past decades with numerous ideas in common but with little interaction between the communities: applications of AGM-like Belief Change and justification-based Ontology Repair. In this paper, we investigate the relationship between pseudo-contraction operations and gentle repairs. Both aim to avoid the complete deletion of sentences when replacing them with weaker versions is enough to prevent the entailment of the unwanted formula. We show the correspondence between concepts on both sides and investigate under which conditions they are equivalent. Furthermore, we propose a unified notation for the two approaches, which might contribute to the integration of the two areas

Royal Army, Fascist Empire: The Regio Esercito on Occupation Duty, 1936–1943

Italy’s invasion of Ethiopia in 1935 ushered in a new imperial phase that aimed to radicalize Italian Fascism at home and abroad. But the military commanders entrusted with conquering and pacifying Fascism’s imperial dominion, and moulding the Fascist “new man” through war, belonged to a conservative monarchist institution with ambiguous ties to Mussolini’s regime. This dissertation explores the relationship between the Royal Italian Army and Fascist empire-building in Africa and Europe, focusing on the Italian military occupation of Ethiopia from 1936 to 1941 and of Yugoslavia from 1941 to 1943. Drawing on ministerial, gubernatorial, division, corps, and army-level archival material, it examines the behaviour, attitudes, and decisions of Italian senior officers through three analytical lenses: political-legal; ideological-cultural; and, military-strategic. The result is a portrait of a military institution that, despite misgivings about Fascist style and bombast, functionally “worked towards the Duce.” Although the army’s involvement in uniquely Fascist policies was restricted by the regime’s expectations that civil authorities would predominate in imperial administration, indigenous resistance to Italian rule ensured that military officers remained involved in most aspects of imperial politics. Yet, despite frequent jurisdictional or tactical conflicts between military authorities and Fascist functionaries, Italian generals never challenged Rome’s principal objectives. Rather, the themes and rhetoric employed by Italian military commanders and propagandists reflected the regime’s official line, from racialized representations of local populations to claims of a “civilizing mission” on the Roman model. Military propaganda aimed to brutalize Italian conscripts on occupation duty by delegitimizing resistance and presenting enemy insurgents and populations in subhuman terms. The army’s counterinsurgency strategies relied on mass repression and violence. Confronted by effective resistance movements, Italian generals resorted to draconian methods that — while rooted in military culture and colonial doctrine dating back to Italy’s nineteenth-century unification — coalesced with Fascism’s exaltation of violence and obsession with the prestige of force. Equating imperial expansion with the status of their nation and institution, and facing military circumstances that elicited a harsh response, a relatively unexceptional group of Italian generals easily found common ground with Fascism
