We propose a model to support aspect-oriented programming in object-oriented languages, expressing general purpose aspects. To apply this model, the developer should implement the abstraction and composition mechanisms as well as one or more strategies defined in it. It could be applied to regular OO languages.

This communication investigates the unsteady flow of viscous incompressible fluid through porous medium induced by periodically heated half filled concentric cylindrical annulus placed horizontally. The boundaries of the annulus are rotating periodically with different angular velocities in the same or opposite directions about their common axis. The governing equations are expressed in terms o...

We report experiments on convection patterns in a cylindrical cell with a large aspect ratio. The uid had a Prandtl number 1. We observed a chaotic pattern consisting of many rotating spirals and other defects in the parameter range where theory predicts that steady straight rolls should be stable. The correlation length of the pattern decreased rapidly with increasing control parameter so that...

This paper studies the shape of an air bubble quasi-statically flowing in the longitudinal direction of narrow channels. Two bottom topographies are treated, i.e., linear and quadratic variations of the gap along the transverse direction. This work analyses the main characteristics of the gas-liquid interface with respect to the wedge aspect ratio. From the convergence of asymptotic, numerical ...

In this paper, we present some of the problems we have found in distributed aspect models and introduce a set of criteria that we consider necessary for a robust distributed aspect system. We outline of a first version of model based on aspects and actors capable of meeting these criteria.

The ability to debug programs composed using aspect-oriented programming (AOP) techniques is critical to the adoption of AOP. Nevertheless, many AOP systems lack adequate support for debugging, making it difficult to diagnose faults and understand the program‘s composition and control flow. We present an AOP debug model that characterizes AOP-specific program composition techniques and AOP-spec...

Simulations are performed according to the Axelrod model of culture dissemination, with modified mechanism of repulsion. Previously, repulsion was considered by Radillo-Diaz et al (Phys. Rev. E 80 (2009) 066107) as dependent on a predefined threshold. Here the probabilities of attraction and repulsion are calculated from the number of cells in the same states. We also investigate the influence ...

The different software modules (e.g., components) that constitute a system are not isolated entities. In fact, they need to interact according to a certain coordination protocol in order to achieve a common goal. This coordination protocol crosscuts the different software modules, hindering their reusability, independence, maintenance and evolution, but these drawbacks can be solved by separati...
