Misconceptions on part-part-whole proportional relationships using proportional division problems

Whole-Part Relationships for Software Component Combination

Reusability is a key factor for the success of the development of low-cost applications. Component-based software engineering (CBSE) aims to address this challenge by providing flexible and easy to use software components. Composability is a key concern of CBSE because software components collaborate with difficulty in spite of the fact that they are known to be compositional. In this paper we ...

Dependency Classifier in Part-Whole Relationships

Many categories of Part-whole relationships have been analyzed earlier. Existing Part-Whole Taxonomies include some form of dependency classifier to account for dependency of whole on the parts. It is shown that the existing notions of dependency partially overlap and are also inadequate. The notion of logical dependency is introduced and it is unified with existing dependency classifier to obt...

Dissolving Ambiguities in UML Whole-Part Relationships

The Unified Modeling Language is the software industry standard for OO graphical modeling languages. However, it does not adequately encompass the meronymic (whole-part) relationships. This paper provides an extension to the UML definition to include the excluded meronymic relationships in a formalized notation and remove the ambiguity of the aggregation definition in UML. Common design pattern...

A Chaos-Based Communication Scheme Using Proportional and Proportional-Integral Observers

In this paper, we propose a new chaos-based communication scheme using the observers. The novelty lies in the masking procedure that is employed to hide the confidential information using the chaotic oscillator. We use a combination of the addition and inclusion methods to mask the information. The performance of two observers, the proportional observer (P-observer) and the proportional integra...
