چکیده

Creating applications using object-oriented frameworks is often difficult, since subclassing plays a too important role. Subclassing is a “white-box” form of reuse, and thus requires the developer to understand the underlying implementation. In the approach described in this paper, class composition is introduced as a form of black-box class reuse. It may be seen to extend the concept of parameterized (generic) classes, especially since it allows mutual relationships as parameters. We illustrate class composition on basis of a design pattern.

A Multi-Formalism Modeling Framework: Formal Definitions, Model Composition and Solution Strategies

In this paper, we present a multi-formalism modeling framework (abbreviated by MFMF) for modeling and simulation. The proposed framework is defined based on the concepts of meta-models and uses object-orientation to overcome the complexities and to enhance the extensibility. The framework can be used as a basis for modeling by various formalisms and to support model composition in a unified man...

Adaptive composition in dynamic service environments

Due to distribution, participant autonomy and lack of local control, service-based systems operate in highly dynamic and uncertain environments. In the face of such dynamism and volatility, the ability to manage service changes and exceptions during composite service execution is a vital requirement. Most current adaptive composition approaches, however, fail to address service changes without ...

An Autonomic Service Oriented Architecture in Computational Engineering Framework

Service Oriented Architecture (SOA) technology enables composition of large and complex computational units out of the available atomic services. Implementation of SOA brings about challenges which include service discovery, service interaction, service composition, robustness, quality of service, security, etc. These challenges are mainly due to the dynamic nature of SOA. SOAmay often need to ...

Composition operators acting on weighted Hilbert spaces of analytic functions

In this paper, we considered composition operators on weighted Hilbert spaces of analytic functions and  observed that a formula for the  essential norm, gives a Hilbert-Schmidt characterization and characterizes the membership in Schatten-class for these operators. Also, closed range composition operators  are investigated.
