Aspect-oriented programming addresses the problem that the implementation of some properties such as error handling and optimization tends to cross-cut the basic functionality. To overcome that problem special languages are used to specify such properties—the so-called aspects—in isolation. The software application is obtained by weaving the aspect code and the implementation of properties corr...

Testing is a vital stage in the development cycle of any application but is often neglected due to the difficulty and expense to perform the stage successfully. This is especially so for distributed applications due to the coordination required to successfully test several distributed components simultaneously. This position paper proposes a framework implemented using Aspect-Oriented Programmi...

Natural language processing systems pose a unique challenge for software architectural design as system complexity has increased continually and systems cannot be easily constructed from loosely coupled modules. Lexical, syntactic, semantic, and pragmatic aspects of linguistic information are tightly coupled in a manner that requires separation of concerns in a special way in design, implementa...

Aspect-oriented programming (AOP) has received considerable interest, in particular as an extension of object-oriented programming. However, current object-oriented software design techniques, such as UML, are not well suited to cope with aspect orientation. In this paper we discuss a design approach, called CoCompose, which supports aspect orientation and software evolution. The CoCompose desi...

Relationships between objects are almost as important to designs as the objects themselves. Most programming languages do not support relationships well, so programmers must implement relationships in terms of more primitive constructs. This paper presents a selection of proto-patterns which describe how aspects can be used to model relationships within programs. By using these patterns, progra...

Learning Objects (LOs) have evolved as a means to organize, encapsulate, and exchange reusable granules of learning material between different e-learning systems. A common problem encountered in practical situations is that conceptually coherent learning material may be distributed across several LOs, a problem which may originate in the way the material is decomposed into LOs. From a maintenan...

    Abstract   Background: Gastroenterologists are required to obtain consent before undertaking   any endoscopic examination. Published data indicate that in practice there are many deficiencies in this process. The aim of this survey was to determine the quality of information given to patients before the endoscopic procedures in Iran .   Methods: A structured questionnaire about patient's in...

We perform event-driven molecular dynamics simulations of a system composed by uniaxial hard ellipsoids for different values of the aspect ratio and packing fraction. We compare the molecular orientational-dependent structure factors previously calculated within the Percus-Yevick approximation with the numerical results. The agreement between theoretical and numerical results is rather satisfac...
