To prevent issues arising from legacy software platforms, adapting to changing customer needs by software evolution is a growing concern of software organizations. How-ever, current practices are pragmatic and subjective, which restricts benchmarking and reduces efficiency. In order to improve evolutionary practices, this paper proposes the Software Functionality Evolution Method (SFEM). The SFEM...
Recently, the autonomic communication networks paradigm has been introduced as a solution to the increasing management complexity of communication networks in the Future Internet. In order to encompass the large-scale nature of these networks, a general consensus has been reached that the supporting autonomic management architectures should be distributed for scalability reasons. However, several...
Enterprise architecture (EA) models the desired relationships between business processes and technology. While the conceptual benefits of EA are many, experience shows that managing the EA can be daunting because of the complex interdependencies among business, technology and the people involved. Having sound EA frameworks and programs are necessary but insufficient conditions for EA success. Effective...
Along with the up-rising of knowledge economy, effective organizing multiple, distributed, heterogeneous knowledge resource and providing high-quality knowledge services for users have been becoming increasingly important. This paper proposes a novel concept of intelligent topic map for knowledge organization and knowledge services, which embodies the multi-level, multi-granularity and inherent relevant...
In current research of agent, agent architecture is an important topic. Architecture of multi-agent system had been proposed to explain the relationship among the policy control layer, the self-control and behavior constraint layer, the organizational management layer and the middle connection layer. In policy control layer, we design two kinds of organizations, and a set of behavior rules, which...
As ubiquitous virtual reality (U-VR) systems become more and more popular and several systems coexist all together, sharing events between them in order to improve the user experience and increase their scope and functionality will be mandatory. Since U-VR systems have a dynamic and decoupled nature, and they have their own event model, we propose in this paper a semantic publish/subscribe infrastructure...
Thanks to the attractions of the multimedia, namely interactivity and multimodality, it seems that web sites and CD-ROMs have the capacity to transmit heritage information to the public. But ultimately they miss real cognitive or educational purposes. Consequently, this article suggests enriching the conception of educational products, combining the potential of video games with the methods of representation...
The future area of communication systems is considered as a representative example of a complex adaptive organization, where several elements, with various computational capabilities and network resources, are interconnected. This evolution renders imperative the need for adaptable and scalable systems that operate in unpredictable environments, having self-management features and the ability to handle...
Digital Earth (DE) is a virtual presentation of the planet based on geographic coordinate, and is an information system with tremendous amount of multiple resolutions and multiple scales data as shown in multiple dimensions. It can visualize the real earth and represent historical phenomena in digital way by using the large amount of data of the earth, and utilizing the computer techniques, image...
Due to the continuously growing possibilities provided by technology and its wider application, today's IT products are becoming more and more complex both from technical and managerial standpoints. Very often, multiple parties are involved in their development. Consequently, the organization of the integration and testing of these products gets increasingly complex. Organisations already encounter...
In this paper we propose a way to facilitate the issue of discovering the eGovernment services that address a citizen's need. This approach is implemented in an application, which we call a semantic portal. The semantic portal is part of our SemanticGov project architecture. The portal's components and its architecture are presented and explained. The portal's conceptual modeling is based on the generic...
An important issue to the adoption of any enterprise architectural approach is the availability of tools to support the development, storage, presentation, analysis, improvement and evolution of enterprise architecture representations. As with enterprise architecture methodologies, enterprise architecture tools to support the architectural development process are still emerging. Most important software...
This paper explores the problem of efficiently permuting data stored in VLSI chips in accordance with a predetermined set of permutations. By connecting chips with shared bus interconnections, as opposed to point-to-point interconnections, we show that the number of pins per chip can often be reduced. For example, for infinitely many n, we exhibit permutation architectures with ⌈√n⌉ pins per chip...
