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...

This paper proposes an empirical approach to the visualization phase of architectural images, employing established concepts, methodologies, and measurement techniques found in media psychology and user-centered studies. The paper proposes a human-centered approach for conceptualizing visualization technologies and evaluating the quality concept of images to simulate a satisfactory architectura...

The Future Internet will be an inherently cyber-physical system, providing native support for many forms of real world interaction, including sensing and actuation. This will place unique requirements on its architectural design, as a vastly heterogeneous set of stake holders tussling to promote business and social opportunities, while addressing technical and incentive barriers. This paper des...

Today's requirements engineering approaches focus on notation and techniques for modeling the intended functionality and qualities of a software system. Little attention has been given to systematically understanding and modeling the relationships between business goals and system qualities, and how these goals are met during architectural design. In particular, modeling must encompass changes ...

Security, as an architectural quality, is often thought to be measured in terms of availability, confidentiality and integrity. These qualities are part of a broader quality dependability. There are inherent tradeoffs among the qualities that define security and dependability. Architectural tactics, or architectural design decisions, that enhance one aspect of dependability can decrease securit...

As part of our research into programmable media processors, we conducted a multimedia workload characterization study. The tight integration of architecture and compiler in any programmable processor requires evaluation of both technologydriven hardware tradeoffs and application-driven architectural tradeoffs. This study explores the latter area, providing an examination of the application-driv...

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...
