The aim of this paper is to introduce our research into the problem of providing support for diierent elements of distributed computing, such as distribution and synchro-nisation, and how this relates to Aspect-Oriented Programming. Our previous research has provided support for individual features of distributed computing, typically by extending the deenition of some existing programming langu...

This paper discusses an approach for the top-down composition of software architectures. First, an architecture is derived that addresses functional requirements only. This architecture contains a number of variability points which are next filled in to address quality concerns. The quality requirements and associated architectural solution fragments are captured in a so-called Feature-Solution...

Service identification step is a basic requirement for a detailed design and implementation of services in a Service Oriented Architecture (SOA). Existing methods for service identification ignore the automation capability while providing human based prescriptive guidelines, which mostly are not applicable at enterprise scales. In this paper, we propose a top down approach to identify automatic...

Applications based on an object-oriented framework can be built by programming against the framework’s reuse interface. Mastering a framework is typically a time-consuming and difficult task. This paper presents a pattern language for developing higher level reuse interfaces for an existing framework. When applying the patterns that constitute the language it is implied that the framework becom...

The ever increasing concerns for energy security, energy efficiency, and sustainable energy is offering various challenges for the power grid. With increasing penetration of the distributed generations, the electricity power system is facing an era of prosumerization, whereby all stakeholders can autonomously produce, consume, import and/or export power. The classical power grid with top-down o...

Fully realizing proposed “value” for both customers and providers is considered as an ultimate goal of developing a good service system. In this paper, based on the mechanism of “value co-production” in services we propose a valueaware service methodology based on Service Model Driven Architecture and Service Quality Function Deployment. Such methodology integrates top-down service model transf...

XML and Service-Oriented Architectures (SOA) make it easier to develop loosely coupled systems, but they do not eliminate the fundamental necessity of communications that there must be an underlying shared model. Because of the popularity of SOA, it becomes increasingly important to be able to quickly and efficiently integrate information systems, rather than using an expensive top-down process...

Service oriented computing provides technologies that enable multiple organizations to integrate their businesses over the Internet. Typical execution behavior in this type of distributed systems involves a set of autonomous peers interacting with each other through messages. Modeling and analysis of interactions among the peers is a crucial problem in this domain due to following reasons: 1) O...

Goal models described with the Goal-oriented Requirement Language (GRL) are amenable to various kinds of analyses, including quantitative and qualitative propagations of satisfaction values. However, most approaches use bottom-up evaluations involving operational semantics that can only answer “what if” questions. This paper introduces a new declarative semantics for GRL based on a constraint-o...

The principal aim of the GOLD project (Grid-based Information Models to Support the Rapid Innovationof New High Value-Added Chemicals) is to carry out research into enabling technology to support theformation, operation and termination of Virtual Organisations (VOs). This technology has beenimplemented in the form of a set of middleware components, which address issues such as trust...
