An architecture-centered method for rapid software development is presented in this paper. It basically follows the guidelines suggested by extreme programming that require highly expressive programming languages (i.e., Java) and CASE tools. As in extreme programming, this method addresses on rapid software development for smallor medium-sized projects. Further, for effective guidance on the de...

Wireless sensor networks have a wide range of applications and can be used for various purposes in different environments. Wireless sensors are small and they are mostly using battery supplies. Communication, sensing and computing have the most influence on performance and power consumption of wireless sensor networks. In this paper we describe layered architecture of wireless sensor network pr...

3D-video systems allow a user to perceive depth in the viewed scene and to display the scene from arbitrary viewpoints interactively and on-demand. This paper presents a prototype implementation of a 3D-video streaming system using an IP network. The architecture of our streaming system is layered, where each information layer conveys a single coded video signal or coded scene-description data....

Lithospheric extension can generate passive margins that bound oceans worldwide. Detailed geological and geophysical studies in present and fossil passive margins have highlighted the complexity of their architecture and their multi-stage deformation history. Previous modeling studies have shown the significant impact of coarse mechanical layering of the lithosphere (2 to 4 layer crust and mant...

Flexibility and adaptability of information systems has become increasingly important especially in Internet-based distributed applications. Class-based methods that are efficient in object-oriented programming tend to become too rigid in Internet environments. A twolayered architecture is here analysed as an alternative approach. The paper attempts to show in what sense Internet and the WWW ar...

India is a country of diversity in language, culture and socio-economic conditions. In order to make use the cutting edge computer aided education technology in this setting, efforts have to be made for proper management of the learning materials by addressing this diversity. In this paper, we present a framework for manual ontology engineering in education domain for managing learning material...

The Internet protocol stack has a layered architecture that resembles an hourglass. The lower and higher layers tend to see frequent innovations, while the protocols at the waist of the hourglass appear to be “ossified”. We propose EvoArch, an abstract model for studying protocol stacks and their evolution. EvoArch is based on a few principles about layered network architectures and their evolu...

Traditional methods of achieving manufacturing system safety exploit the highly repetitive nature of traditional manufacturing operations. With agile manufacturing systems, the interactions between machinery and personnel (operator, set-up, and maintenance) become less predictable. The smaller batches and more varied product drive hardware and software designs that are difficult to model and im...

The effective and reliable coordination of agent activities is a momentous problem for Multi–Agent System (MAS) developers. Particularly challenging is the decentralized coordination of agents that enables systems to exhibit self–organization. Natural phenomena typically serve as design metaphors and developers apply Decentralized Coordination Mechanisms (DCMs) that have been inferred from biol...

Current trends in embedded systems software for the automotive domain aim at an increase of reusability, exchangeability and maintainability, and thus at a significant reduction of timeand costs-to-market. One way to reach these goals is the adaption of Component Based Software Engineering (CBSE) for resource constrained embedded systems. The Automotive Open System Architecture (AUTOSAR), an up...
