More and more software projects are using COTS (commercial-off-the-shelf) components. One of the most challenging problems in COTS-based development is to evolve a system to follow changes in the customer requirements. It is therefore important to increase the changeability of the COTS-based system, so that new component can easily replace the problematic COTS components. Aspect-Oriented Progra...

Antioxidant potential (AOP) is not only the property of the matrix analyzed but also depends greatly on the methodology used. The chromogenic radicals 2,2'-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) (ABTS•+), 2,2-diphenyl-1-picrylhydrazyl (DPPH•) and Folin-Ciocalteu (FC) assay were applied to estimate how the method and the composition of the assay solvent influence the AOP determined fo...

The chemokine receptor CCR5 is a cofactor for the entry of R5 tropic strains of human immunodeficiency viruses (HIV)-1 and -2 and simian immunodeficiency virus. Cells susceptible to infection by these viruses can be protected by treatment with the CCR5 ligands regulated on activation, normal T cell expressed and secreted (RANTES), MIP-1alpha, and MIP-1beta. A major component of the mechanism th...

Many commercial applications provide customer services over the web like flight tracking, emergency notification, order inquiry etc. VoiceXML is an enabling technology for creating streamlined speech-based interface for such web-based information services. Whereas in computing, aspect-oriented programming (AOP) is a programming paradigm, which aims to increase modularity. AOP includes programmi...

Dynamic AOP (Aspect-Oriented Programming) is receiving growing interests in both the academia and the industry. Since it allows weaving aspects with a program at runtime, it is useful for rapid prototyping and adaptive software. However, the previous implementations of dynamic AOP systems suffered from serious performance penalties. This paper presents our new efficient dynamic AOP system in Ja...

The development of in vitro testing strategies may achieve a cost-effective generation of comprehensive datasets on a large number of chemicals, according to the requirements of the European Regulation REACH. Much emphasis is placed on in vitro methods based on subcellular mechanisms (e.g., nuclear receptor interaction), but it is necessary to define the predictive value of molecular or biochem...

In spite of themodularizationbene!ts supportedby theAspect-Orientedprogrammingparadigm, di"erent usability issues have hindered its adoption.#e decoupling between aspect de!nitions and base code, and the compile-time weaving mechanism adopted by di"erent AOP languages, require developers to manage the consistency between base code and aspect code themselves.#ese mechanisms create opportunities ...

We present how we used Aspect-Oriented Programming (AOP) to ease the development of Multi-Agent Systems (MAS). Our study focuses on the Aalaadin MAS model. We make use of AOP at both the conceptual level of Aalaadin and the implementation level. On the conceptual level, we introduced in Aalaadin AOP concepts. It results in unifying the group concept of Aalaadin with the aspect concept. This uni...

AOP [2] introduced the notion of crosscutting concerns in programming. An aspect groups a crosscut (aka. pointcut in Aspect-J [3]) which relates several points of interest (aka. join points) of the base application with an action (aka. advice) to be performed. This article argues for a clear separation of crosscut and action de nitions. The tools for AOP currently available support only simple ...

The classic challenge in writing object-oriented programs (OOP) is finding the right decomposition into classes and objects. This problem arises whenever programmers need to deal with crosscutting concerns. Aspect Oriented Programming (AOP) is a well known methodology to overcome this issue by modularizing crosscutting concerns using aspects. Programmers are slowly realizing the importance of A...
