Attention to aspect oriented programming (AOP) is rapidly growing as its benefits in large software system development and maintenance are increasingly recognized. However, existing large software systems, which could benefit most from refactoring into AOP, still remain unchanged in practice, due to the high cost of the refactoring. Automatic identification and extraction of aspects would not o...

Aspect-oriented Programming (AOP) Methodology has been investigated in the design and implementation of a web application: Online music Store. The Aspect.NET Framework is implemented as an add-in to visual studio.NET. That means, the user can use Aspect.NET in combination to the integration development environment provided by Visual Studio.NET and its numerous comfortable features to develop so...

Aspect Oriented Programming (AOP) is a software development programming technique that facilitates the modularization of cross cutting concerns, for example logging, security and error handling [4]. Agile Processes, such as eXreme Programming and SCRUM are software development methodologies that promote iterative and incremental design and development to projects [2]. This paper will test the h...

several authors have indicated that pcp is a toxic chemical and recalcitrant to biodegradation. aops is one of the moste effective process for degradation of persistant compound.since the mineralization of recalcitrant compound by aops (advanced oxidation processes) often requires long reaction time and strong doses of oxidant, the combination of this process with biological one, considered as ...

More and more software developers get in touch with aspect-oriented programming (AOP). By providing means to modularize the implementation of crosscutting concerns, it stands for more reusability, less coupling between modules, and better separation of concerns in general. Today, solid tool support for AOP is available, for instance, by JBoss (JBoss AOP), BEA (AspectWerkz), and IBM (AspectJ and...

Skin sensitization is an important toxicological endpoint for chemical hazard determination and safety assessment. Prediction of chemical skin sensitizer had traditionally relied on data from rodent models. The development of the adverse outcome pathway (AOP) and associated alternative in vitro assays have reshaped the assessment of skin sensitizers. The integration of multiple assays as key ev...

In this paper we study the Arc Orienteering Problem in directed and undirected graphs. To the best of our knowledge, we give the fist approximation algorithms for both the undirected and the directed versions of the problem. Our main results are the following: (i) We give an O( log 2(m) log log(m) )−approximation algorithm for the AOP in directed graphs, where m is the number of arcs of the gra...

Adenovirus has consistently been observed to be the most resistant known pathogen to disinfection by ultraviolet light. This has had an impact on regulations set by the United States Environmental Protection Agency regarding the use of UV disinfection for virus inactivation in groundwater and surface water. In this study, enhancement of UV inactivation of adenovirus was evaluated when hydrogen ...
