Architectural patterns(styles) are important artifacts containing specialized design knowledge to build good-quality systems. Complex systems often exhibit several architectural patterns in their design which leads to the need of architectural pattern composition. Unfortunately, information about the composition of patterns tend to be vaporized right after the composition process which causes p...

An important way that the reliability of a software system is enhanced is through the implementation of specific run-time measures called runtime tactics. Because reliability is a system-wide property, tactic implementations affect the software structure and behavior at the system, or architectural level. For a given architecture, different tactics may be a better or worse fit for the architect...

This paper presents an architectural pattern for structuring adaptive applications using aspectoriented programming in order to obtain separation of concerns. It is composed of known and novel patterns organized so as to provide good maintainability and modularity. 1

This paper introduces an approach to describing and selecting design patterns for developing communication components of parallel programs. The approach uses the kind of communication requirements of the architectural pattern whose processing components have to be communicated, along with characteristics and features of the parallel hardware platform and programming language synchronisation mec...

A key objective for ubiquitous environments is to enable system interoperability between system’s components that are highly heterogeneous. In particular, the challenge is to embed in the system architecture the necessary support to cope with behavioral diversity in order to allow components to coordinate and communicate. The continuously evolving environment further asks for an automated and o...

Context: Many software architectural decisions are group decisions rather than decisions made by individuals. Consensus in a group of decision makers increases the acceptance of a decision among decision makers and their confidence in that decision. Furthermore, going through the process of reaching consensus means that decision makers understand better the decision (including the decision topi...

A key objective for ubiquitous environments is to enable system interoperability between system’s components that are highly heterogeneous. In particular, the challenge is to embed in the system architecture the necessary support to cope with behavioral diversity in order to allow components to coordinate and communicate. In this paper we present the design building blocks for the dynamic and o...
