As computational complexity of systems continues to increase, the amount of maintenance required to keep them operational will also increase. Autonomic systems have the aim of reducing the amount of maintenance required by performing certain levels of maintenance themselves. This paper outlines the case of using dynamic AOP to implement such a system. The benefits and issues arising from using ...

Aspect-Oriented Programming (AOP) has emerged recently as a language concept for expressing cross-cutting concerns, mainly in object-oriented software. Since then, the concept has been applied to a wide variety of other contexts. In this paper, we explore some cross-cutting concerns for parallel programs of reactive systems: we propose a notion of aspect and a weaving mechanism, in a core langu...

Aspect-Oriented Programming (AOP) is an emerging technology whose goal is to modularize concerns that cross-cut multiple classes. The purpose of this report is to describe how one of the main representatives of AOP, namely AspectJ, was used to implement a simple yet illustrative product-line of graph algorithms so that we can focus on the implementation details. We expect that studies like this...

So far, there is no satisfactory means to safely combine aspects that have been developed independently. In the general case, the process of jointly applying different aspects is not guaranteed to produce complete and unambiguous results. This paper shows that in the relevant case of pure interface modifications, completeness, uniqueness and independent extensibility can be ensured. This result...

This paper describes a novel application for Aspect-Oriented Programming (AOP). By combining the concepts of Business Process Management and AOP, we present an approach for enabling the creation of flexible and dynamic business processes, given a set of aspects defined by the participants in the process. We call this approach AspectOrientated Process Engineering (ASOPE). An example of an applic...

[acyment,nicok,raltman,fasteasuain]@dc.uba.ar ABSTRACT AOP systems evolvability is severely affected by the tight coupling between aspects and base code. This paper identifies the advice fragility problem, originated in the advice’s need to access the application context while being oblivious to base code details. Proposed solutions to the pointcut fragility problem have generally put forward v...

Aspect-Oriented Programming (AOP) offers new insights and tools for the modular development of systems with cross-cutting features. Current tool support for AOP is provided mainly in the form of code-level constructs. This paper presents a way to express crosscutting features as logical invariants and then to generate the kind of code that is usually produced from manually written aspects. In o...

This grant supported Laurie Hendren (McGill, Canada) as a visiting fellow for joint research with the Principal Investigator, Oege de Moor (Oxford). Hendren was on sabbatical leave at Oxford for the period August 2003 to July 2004. As a large part of this project deals with aspectoriented programming (AOP), we provide a brief introduction to AOP for reviewers not familiar with this research area.

Advanced oxidation processes (AOPs) are gaining traction as they offer mineralization potential rather than transferring contaminants between media. However, AOPs operated with limited energy and/or chemical inputs can exacerbate disinfection byproduct (DBP) formation, even as precursors such as dissolved organic carbon, UV254, and specific UV absorbance (SUVA) decrease. This study examined the...

Quantitative trait loci (QTL) mapping studies enable identification of loci that are part of regulatory networks controlling various phenotypes. Detailed investigations of genes within these loci are required to ultimately understand the function of individual genes and how they interact with other players in the network. In this study, we use transgenic plants in combination with natural varia...
