State-of-the-art in integrated vehicle health management

Integrated vehicle health management (IVHM) is a collection of data relevant to the present and future performance of a vehicle system and its transformation into information can be used to support operational decisions. This design and operation concept embraces an integration of sensors, communication technologies, and artificial intelligence to provide vehicle-wide abilities to diagnose problems and recommend solutions. This article aims to report the state-of-the-art of IVHM research by presenting a systematic review of the literature. The literature from different sources is collated and analysed, and the major emerging themes are presented. On this basis, the article describes the IVHM concept and its evolution, discusses configurations and existing applications along with main drivers, potential benefits and barriers to adoption, summarizes design guidelines and available methods, and identifies future research challenges.

Physics and mathematics of dispersion-managed optical solitons

We review the main physical and mathematical properties of dispersion-managed (DM) optical solitons. Theory of DM solitons can be presented at two levels of accuracy: first, simple, but nevertheless, quantitative models based on ordinary differential equations governing evolution of the soliton width and phase parameter (the so-called chirp); and second, a comprehensive path-average theory that is capable of describing in detail both the fine structure of DM soliton form and its evolution along the fiber line. An analogy between DM soliton and a macroscopic nonlinear quantum oscillator model is also discussed. © 2003 Académie des sciences/Éditions scientifiques et médicales Elsevier SAS.

Introduction – transnational organised crime and terrorism:different peas, same pod

The nexus between terrorism and organised crime consists in a strategic alliance between two non-state actors, able to exploit illegal markets, threaten the security of individuals, and influence policy-making on a global level. Recent Europol reports have pointed towards the importance of studying the links between organised crime and terrorist groups, and have underlined that the nature and extent of these connections have seldom been addressed from an academic perspective. Considering the degree of dangerousness that both organised crime and terrorism currently represent in the world, the collusion between these two phenomena is of urgent contemporary interest. Basing itself on geographical case-studies, this edited volume aims at contributing to the existing literature in three ways: by enriching the empirical knowledge on the nature of the crime-terror nexus and its evolution; by exploring the impact of the nexus within different economic, political and societal contexts; and by expanding on its theoretical conceptualization.
