In this paper, we present new pointcuts and primitives to Aspect-Oriented Programming (AOP) languages that are needed for systematic hardening of security concerns. The two proposed pointcuts allow to identify particular join points in a program’s control-flow graph (CFG). The first one is the GAFlow, Closest Guaranteed Ancestor, which returns the closest ancestor join point to the pointcuts of...

Web-based collaboration platforms evolve into service-oriented architectures by promoting composite and user-enriched services. In such platforms, the collaborations typically include both human and software services, thus creating highly dynamic and complex interactions. However, in existing platforms users cannot specify different interaction interfaces as services that can be reused in vario...

Collaboration flow management is a new paradigm for virtual team support which departs from the classical ‘workflow management’ and ‘collaborative computing’ paradigms. The aim is to support the opportunistic flow of collaboration within a distributed project, considered as a living and selforganizing system. Such a flow includes informal and formal, synchronous and asynchronous, task-oriented ...

The connection oriented flow control method is subject to a high retry rate with the heavy network load. An asynchronous link induces an extra latency when its bandwidth is directly enlarged by increasing the wire count. In this paper, a new dynamic link allocation flow control method is proposed. By dynamically allocating the sub-links on a link to multiple frames, it decreases the retry rate ...

This paper summarizes a function-based approach to create 2D flow animations. We use periodic functions to create cyclical animations that represent 2D flow. These periodic functions are constructed with an extremely simple algorithm from a set of oriented lines. The speed and orientation of the flow are described directly by the orientation and the lengths of these oriented lines. The resultin...
