Received: 6 June 2008 Revised: 16 September 2008 2nd Revision: 29 September 2008 Accepted: 30 September 2008 Abstract This study questions the traditional view of software architecture as a specification that needs only be understood by software architects and engineers. Based on an intensive study of three software-producing organizations, we identify multiple metaphors (‘Blueprint,’ ‘Literatu...

We present the architecture of an Open Data and Linked Data platform for "EnhAnced Government LEarning” (EAGLE), which aim is to help local governments to keep up with fast-changing trends in public administration (PA) by adopting technology-enhanced learning (TEL) methods. EAGLE uses Linked Open Data tools: Apache Marmotta and Apache Stanbol.

The International Telecommunications Union (ITU) has endorsed High Altitude Platforms (HAPs) as an alternative means of providing UMTS wireless services. The utilisation of HAPs (High Altitude Platforms) in the access part of the upcoming UMTS networks can provide great flexibility to UMTS from the viewpoint of service provisions and fast infrastructure installation. Moreover, they offer these ...

The concept of provenance is already well understood in the study of fine art where it refers to the trusted, documented history of some work of art. Given that documented history, the object attains an authority that allows scholars to understand and appreciate its importance and context relative to other works of art. This same concept of provenance may also be applied to data and information...

In the last two decades, software architecture has played a central role in the development of software systems. It provides a high-level description for large-size and complex systems using suitable abstractions of the system’s components and their interactions. In our work, the software architecture is described using a formal Architecture Description Language (ADL) designed in the ArchWare E...

This paper addresses the issue of re-usability in personalised web-based learning environments. The paper focuses on the work of the European IST Project KOD “Knowledge on Demand”, towards the definition of an architecture, and the implementation of a system that promotes re-usable adaptive educational e-content. The proposed architecture is presented, and the elements of the KOD prototype syst...

Europe has taken an early lead in the development and deployment of All applications through the adoption of relatively narrow, ad-hoc architectures. These tend to be application-specific and the approach has facilitated rapid development. Meanwhile the US is developing a singie nationai iVHS architecture funded and directed at national level by USDOT. This paper provides a brief description of...

This paper reports on our current eeort for applying probabilistic path planning techniques to logistics and operation in huge industrial installations (e.g., power plants). We show how the speciic domain constraints impose a dedicated software architecture to take advantage of the generality of probabilistic approaches. In addition, such an architecture should be compatible with existing CAD s...

An architecture for a distributed and adaptive multi-sensor fusion engine is described. The engine is developed to improve the protection of European armed forces against the threats troops are facing in urban environments. In particular, the engine needs to be scalable, flexible to quickly adjust to different missions and mission goals, easily extendable and suited for distributed implementati...

technology developments leading to the architecture and to the selection and definition of new standards for a distributed digital library of geospatial services. Furthermore the paper describes the requirements for the open service oriented architecture, which may form the enabling element of a widely distributed digital library. The paper details how the supporting protocols are being defined...
