Quantum theory-inspired search

With the huge number and diversity of the users, the advertising products and services, the rapid growth of online multimedia resources, the context of information needs are even more broad and complex. Although research in search engine technology has led to various models over the past three decades, the investigation for effectively integrating the dimensions of context to deploy advanced search technology has been limited due to the lack of a unified modeling and evaluation framework. Quantum Theory (QT) has created new and unprecedented means for communicating and computing. Besides computer science, optics, electronics, physics, QT and search engine technology can be combined: interference in user interaction; entanglement in cognition; superposition in word meaning; non-classical probability in information ranking; complex vector spaces in multimedia search. This paper highlights our recent results on QT-inspired search engine technology

Man-vehicle systems research facility: Design and operating characteristics

The Man-Vehicle Systems Research Facility (MVSRF) provides the capability of simulating aircraft (two with full crews), en route and terminal air traffic control and aircrew interactions, and advanced cockpit (1995) display representative of future generations of aircraft, all within the full mission context. The characteristics of this facility derive from research, addressing critical human factors issues that pertain to: (1) information requirements for the utilization and integration of advanced electronic display systems, (2) the interaction and distribution of responsibilities between aircrews and ground controllers, and (3) the automation of aircrew functions. This research has emphasized the need for high fidelity in simulations and for the capability to conduct full mission simulations of relevant aircraft operations. This report briefly describes the MVSRF design and operating characteristics

Needs before means: the dialectics of learning and technology

The general argument advanced in this paper is that in the changing context of present-day higher education it is vital that our educational purposes and student needs are clarified before decisions are taken about the means, including the use of learning technology, of satisfying those purposes and needs. The development of a critical understanding is still seen as the central purpose of higher education even in the context of a more vocationally relevant mass higher education. It is argued here that dialogue is the key to critical learning based on a process of dialectical communication. The task then is to construct an understanding learning environment which fosters interaction between students, staff and resources, reconciling individual needs with collective purposes. The specific role of learning technology as a means of encouraging dialogue within a learning environment is illustrated through examples of language learning such as TLTP CKS33 and the RACE Hipernet Project. Through a dialectical process, the appropriate use of learning technologies in meeting students' changing needs can be progressively refined

Context-aware platform for mobile data management

Interaction design is a major issue for mobile information systems in terms of not only the choice of input/output channels and presentation of information, but also the application of context-awareness. To support experimentation with these factors, we have developed platforms to support the rapid prototyping of multi-channel, multi-modal, context-aware applications. The Java-based platform presented here is based on an integration of a cross-media link server and an object-oriented framework for advanced content publishing, along with a Client Controller and Context Engine. We also describe how this platform was used to develop a mobile tourist information system for an international arts festival where interaction was based on a combination of interactive paper and speech outpu

Preventing Advanced Persistent Threats in Complex Control Networks

An Advanced Persistent Threat (APT) is an emerging attack against Industrial Control and Automation Systems, that is executed over a long period of time and is difficult to detect. In this context, graph theory can be applied to model the interaction among nodes and the complex attacks affecting them, as well as to design recovery techniques that ensure the survivability of the network. Accordingly, we leverage a decision model to study how a set of hierarchically selected nodes can collaborate to detect an APT within the network, concerning the presence of changes in its topology. Moreover, we implement a response service based on redundant links that dynamically uses a secret sharing scheme and applies a flexible routing protocol depending on the severity of the attack. The ultimate goal is twofold: ensuring the reachability between nodes despite the changes and preventing the path followed by messages from being discovered.Universidad de Málaga.

Colliding Winds in Low-Mass Binary Star Systems: wind interactions and implications for habitable planets

Context. In binary star systems, the winds from the two components impact each other, leading to strong shocks and regions of enhanced density and temperature. Potentially habitable circumbinary planets must continually be exposed to these interactions regions. Aims. We study, for the first time, the interactions between winds from low-mass stars in a binary system, to show the wind conditions seen by potentially habitable circumbinary planets. Methods. We use the advanced 3D numerical hydrodynamic code Nurgush to model the wind interactions of two identical winds from two solar mass stars with circular orbits and a binary separation of 0.5 AU. As input into this model, we use a 1D hydrodynamic simulation of the solar wind, run using the Versatile Advection Code. We derive the locations of stable and habitable orbits in this system to explore what wind conditions potentially habitable planets will be exposed to during their orbits. Results. Our wind interaction simulations result in the formation of two strong shock waves separated by a region of enhanced density and temperature. The wind-wind interaction region has a spiral shape due to Coriolis forces generated by the orbital motions of the two stars. The stable and habitable zone in this system extends from approximately 1.4 AU to 2.4 AU. (TRUNCATED)Comment: 15 pages, 11 figures, to be published in A&

THE USE of VEHICLE DATA in ADAS DEVELOPMENT, VERIFICATION and FOLLOW-UP on the SYSTEM

Advanced Driver Assistance Systems (ADAS) require a high level of interaction between the driver and the system, depending on driving context at a particular moment. Context-aware ADAS evaluation based on vehicle data is the most prominent way to assess the complexity of ADAS interactions. In this study, we conducted interviews with the ADAS development team at Volvo Cars to understand the role of vehicle data in the ADAS development and evaluation. The interviews\u27 analysis reveals strategies for improvement of current practices for vehicle data-driven ADAS evaluation

The statutes of Iona : the archipelagic context

In recent decades, understanding of the historical development of Britain and Ireland has benefited significantly from the adoption of integrated approaches to the history of Britain and Ireland. While traditional national histories laid the foundation, the new British and Irish historiography has teased out many of the nuances arising from the interaction between the three kingdoms or four nations of Britain and Ireland. This approach has produced much scholarly work for both the medieval and early modern periods, although modern historians are still grappling with attempts to write a genuinely British history.1 For the early modern period in particular, the "three kingdoms" debate of the seventeenth century has advanced awareness of the complexity of regal union and the problems associated with one king ruling three distinct kingdoms. It is within this wider British context that James VI and I's efforts to integrate his three kingdoms need to be viewed. Although James's "earnist dispositioun to perfyte that Union"- brought about by his succession to the English throne on 1603-was thwarted by both the English and Scottish parliaments, James could not afford to govern either kingdom in isolation
