[more ▼] Many large-scale Internet applications optimize their overlay network to reduce latencies. Embedding coordinate systems like Vivaldi are valuable tools for this new range of applications since they propose light-weight algorithms that permit to estimate the latency between any pair of nodes without having to contact them first. It has been recently demonstrated that coordinate systems in general and Vivaldi in particular are sensible to attacks. Typically, nodes can lie about their coordinate and distort the coordinate space. In this paper, we propose a formal reputation model to detect misbehaving nodes and propose a reputation adaptation of Vivaldi called RVivaldi. We evaluate the performance of RVivaldi using the King dataset and show that RVivaldi is less sensitive to malicious nodes than Vivaldi.

[more ▼] We examine bond market reactions to the announcement of operational losses by financial companies. Thanks to the fact the corporate debt is senior to equity, we interpret the cumulated abnormal returns on the bond market of the companies having suffered those losses as a pure reputational impact of operational loss announcements. For a given operational loss, bond returns might be affected at up to three different periods: at the first press release date, when the company recognizes the loss itself and at the settlement date. These impacts hold stronger than for common stocks. We also study the effect of investors' knowledge of the loss amount, and show that the type of operational event and the proportion of the loss in the firm's market value influence the effect of the loss announcement. Cross-sectional analysis indicates that the abnormal return is mostly affected by market-based characteristics for the first press release date, while firm-related characteristics largely affect bond returns upon loss recognition.

[more ▼] Atypical myopathy (AM) or atypical myoglobinuria, is an acute and massive rhabdomyolysis syndrom. Most of cases occurs during autumn and spring, and affects grazing horses, often after windy bad weather. Death occurs within 72 hours in the majority of cases. In autumn 2002, the first French case was reported to the French national Network for epidemiological surveillance of Equine Diseases (RESPE). The condition was formerly described in 1985, and cases are reported each year in Europe (Great Britain, Germany, Belgium, Switzerland The Netherlands, France) and also in the USA. The AMAG (Atypical Myopathy Alert Group) collects epidemiological and clinical data. Determination of etiological hypothesis, symptoms and risk factors were obtained from these studies to help veterinary practitioners to better diagnose MA.

[more ▼] Off the coast of Saintes-Marie-de-la-Mer, in the confluence of one of the ancient branches of the Rhone, eleven wrecks transporting mainly iron have been discovered. Dated from the turn of our era (the end of the first century BC - first century AD), each one delivers between 20 and 150 tons of iron which break down into eight standardized semi-finished products (types and subtypes included), sometimes stamped. We propose to specify these typological and epigraphic characteristics through archeometric studies undertaken on around fifty of these bars. Metallographic and chemical characteristics are then established in each unit. They make it possible to understand the technical reality of a complex typology and to refine our knowledge of the ferrous production networks in the Roman Mediterranean world.

[more ▼] The aim of the Journées des Sciences du Muscle et Technologies de la Viande is to give a report on the most recent research works to the technical, economical and scientific actors of the meat production and transformation chain. The topics of these researches and the organisations that carry them out evolve with time, depending in particular to the needs of the actors (producers, manufacturers, distributors, consumers) and of the socio-economic context. In addition, these researches fit themselves more than ever in an international context, particularly on a European level. The objective of this lecture, a somewhat ambitious idea, is to give an overview of the researches undertaken in Europe in muscle science and meat technology field.

[more ▼] Bird strike issues are known to cause substantial losses to the civil aviation industry in terms of damage and delay every year. Rules of bird strike resistance are included in many important regulations and guidelines of civil aviation. Based on these rules, attentions should be paid during the design and analysis process for those structures that might be apt to suffer from bird strike as leading edge, radar dome, wind shield and vertical tail. This paper describes a new software infrastructure for bird-strike design and analysis. The bird-strike resistance synthetic analysis platform is a platform that incarnates new research and innovations in bird-strike dynamic strength analysis of our research group. The platform was implement using finite element method and parametric design method based on ESI Pam-crash software, and involves a dynamic performance database of the typical aviation material, a typical structure database for bird-strike resistance, a post-processing modular for result reveal, and an estimation modular for energy absorbing. The material database covers the key constitutive model constants for many common aviation materials. Different bird model for Lagrange, Euler, and SPH algorithm are also covered to fit for different impact speed simulation. The typical structure database are very helpful to the designers because it provides the parametric model of some special bird-strike resistance structures to improve the energy absorbing ability subject to impact. The post-processing modular enables the contour and curve display for the results. The estimation modular gives judgments on the energy absorbing structure by utilizing the criterion and provides proper advices for the design for different cases.

[more ▼] Unmanned Aerial Vehicle (UA V) structures are prone to damage during their service lives, caused by abominable environment factors. Its structural health monitoring can be effective in reducing maintenance costs and increasing service life to ensure safe and reliable operation. Two different damaged modal parameters based on modal analysis is discussed in this paper in order to develop an efficient damage identification technique for the UA V wing structures. Its structure modal is a natural attribute of structures, and apparently one of the most important parameters of structure dynamic characteristics. For a well designed aircraft wings structures, its modal pattern should be continuous without local mode. Therefore, based on the modal analysis utilizing numerical methods for a damaged structure, damages location and its extent can be revealed and damage level can be evaluated. All the numerical results illustrated these method are efficient and feasible for structural damage detection. And its can be utilized in structure [less ▲] Detailed reference viewed: 13 (3 ULg) |
