An emergent domain that raises some unique engineering challenges is that of software architectures to convert large bodies of unstructured data to human-usable knowledge, such as in the domain of socio-cultural information analysis. We report on an architecture based on Service-Oriented Architectures that we are applying in this domain. We list the requirements that such an architecture must s...

We are investigating the application of aspect-oriented principles as an aid toward improving the capabilities of domain-specific modeling. The approach, in general, provides transformations by weaving modeling aspects into a base model. The modeling aspects provide variation points within the model and can be used to drive the synthesis of the model into different artifacts. In this brief posi...

Anycast is a new IPv6 feature that supports service–oriented address assignments in IPv6 networks. However, because there are no protocol standards or even consensus on routing protocols, inter–segment anycast communications are not yet available. In this paper, we first discuss problems and solutions on inter–segment anycast communications. Based on our findings, we propose two routing protoco...

Aspect-Oriented Programming (AOP) has emerged recently as a language concept for expressing cross-cutting concerns, mainly in object-oriented software. Since then, the concept has been applied to a wide variety of other contexts. In this paper, we explore some cross-cutting concerns for parallel programs of reactive systems: we propose an aspect language, Larissa, and a weaving mechanism, in a ...

The material presented in this paper is focused on the characteristics of open computational systems and, in particular, the issue of coordinating behavior in such systems, i.e. systemic coordination. Firstly, we introduce a conceptual framework for characterizing systemic coordination at different levels abstraction. Secondly, challenges and opportunities of this framework is outlined as a mat...

From a labour-intensive and paper-based door-keeping function Customs control is aiming now towards international trade facilitation in a way that is both efficient and secure. Digitalization of documents and automation of processes plays an important role in this transition. However, the use of modern technology, in particular SOA, is not yet optimal. The research objective of this paper is to...

Service oriented architectures (SOA) herald a new generation of application systems. Whereas current systems were to be chosen and operated as self-contained systems of individual vendors, service oriented architectures allow for integrating application functionality from different sources internal or external to a company according to individual needs within a specific context. Vendors of ERP ...

the advantages and special characteristics of service oriented architecture and expansion of employing such architecture have brought security topics which are different in some cases from the security principles of traditional information systems. in this article our aim is the examination of various indices of security and the presentation of strategies for security in information systems by ...

the the main objective of this research paper is to present 3-d elasticity solution for free vibration analysis of elastically supported continuously graded carbon nanotube-reinforced (cgcntr) annular plates. the volume fractions of oriented, straight single-walled carbon nanotubes (swcnts) are assumed to be graded in the thickness direction. an equivalent continuum model based on the eshelby-m...

As a security policy model evolves, the design of security systems using that model could become increasingly complicated. It is necessary to come up with an approach to guide the development, reuse and evolution of the design. In this paper, we propose an aspect-oriented design approach to designing flexible and extensible security systems. A case study demonstrates that such an approach has m...
