An approach on modeling traversing features in concurrent software system was presented, which is based on aspect-oriented techniques and statecharts of unified modeling language (UML). Modeled with UML statecharts diagrams, the primary system functions and corresponding traversal features are enveloped into various orthogonal regions of a composite state respectively. The mutual relationships between...

Aspect-oriented programming, as an ideal candidate to encapsulate crosscutting functionalities, has been adopted for run-time monitoring, failure forecasting, fault tolerance and etc. While, nowadays aspect-oriented techniques are not used to multi-core computing platforms. To cope with that, this paper makes AspectJ, a typical aspect-oriented programming language, suitable for parallel program, and...
Several requirements engineering approaches already provide means for the detection, specification and composition of crosscutting requirements during the preliminary stages of software development. Without the aspect-oriented techniques, the aspectual requirements would still be scattered by the various system components, impeding its implementation in a more modularized way, with a more understandable...
Our goal is to address the large number of variations arising in the context of software product lines, and to manage feature interactions and dependencies resulting from configuration through composition of such variations. To achieve this, we need: (1) to study and understand the various kinds of interferences between features and how they emerge; (2) to enhance the support for the management, detection...
Today's society increasingly depends on software systems deployed in large companies, banks, airports, and so on. These systems must be available 24/7 and continuously adapt to varying environmental conditions and requirements. Such dynamically adaptive systems exhibit degrees of variability that depend on user needs and runtime fluctuations in their contexts. The paper presents an approach for specifying...

Software product lines (SPLs) based development aims at saving development cost as well as reducing time-to-market by structured reuse of base assets for a group of similar products. Requirements of product line are organized into features in FOA (Feature-Oriented Analysis) approach. Commonalities and variabilities among products in a product line are showed in the features. The effectiveness of a...
Model-driven architecture (MDA) is introduced to shorten the software development time, produce better quality of code and promote the reuse of software artifacts. On the other hand, aspect-oriented programming (AOP) is motivated by the need to create decoupled systems, which are easier to maintain. As a result, it can be argued that adopting AOP and MDA side-by-side will provide advantages from both...
Testing is regarded as one of the most resource consuming tasks of an average software project. A common goal of testing related activities is to make sure that requirements are satisfied by the implementation. Although existing tools are often effective in functional testing, emerging nonfunctional requirements set new demands. Aspect-oriented techniques offer a promising approach for capturing such...
Automated tests have been widely used as a supporting mechanism during software development and maintenance activities. It improves the confidence on software releases as it seeks to uncover regression bugs, and serves as a live documentation which is very useful when evolving systems. Concerning multi agent systems (MASs), some characteristics such as agent autonomy and asynchronous message-based...
Being one of the most promising current technologies, Web services are at the crossing of distributed computing and loosely coupled systems. Although vendors provide multiple platforms for service implementation, service integrators, developers and providers demand approaches for managing service-oriented applications at all stages of development. In this sense, approaches such as model-driven development...
