-----------------------------------------------ABSTRACT-----------------------------------------------Nowadays, different kinds of processors are appearing in the computer market, therefore it is necessary to observe the performance of these processors at the early stage of computation of object oriented programs. In this context, the present paper deals with the evaluation of the performance o...

Over the last years, object-orientation has been recognized as a suitable technique for the modeling and design of real-time systems. Although modeling strategies archived a high-level of maturity, current run-time infrastructures have not reached “the Nirvana”. The so called middleware, which provide adequate abstractions for programming object-oriented real-time applications, still demands lo...

One of the issues that developers of service-oriented systems currently discuss is the lack of practical, but formal modeling notations and tools that can address the many different, important aspects. This paper presents an approach to model structural and behavioral properties of service-oriented systems with UML and OCL models. Essential service-oriented concepts as service request, service ...

This technological era is raising new challenges towards the storage and management of data, that is getting more complex and imprecise with the evolution of utilization of computer engineering in most of the areas of society. To confront the arising challenges, database researchers has introduced fuzzy object oriented databases, by blending the concepts of database management system, object or...

The object-oriented modeling language Dymola allows the physical modeling of large interconnected systems based on model components from diierent engineering domains. It generates symbolic code for diierent target simulators. In this paper, a Dymola class library for the eecient generation of the equations of motion for multibody systems is presented. The library is based on an O(n) algorithm w...

This paper presents an object-oriented database model for broadband telecommuni-cation networks, which can be used both for network management and for network planning purposes. The object-oriented data model has been developed using the parallel object-oriented speciication language Maude 8,11], which allows us to de-ne not only structural aspects of the database, but also procedural aspects. ...

Comparison of Relational Database and Object Oriented. Database This report presents the comparison between object oriented database and relational. The difference is mostly in the way the database is used. The difference is Object-Relational data modeling supports some objectoriented concepts, while still. Semantic overloading: No mechanism to distinguish between entities and Very influenced b...

Teaching introductory object-oriented programming presents considerable challenges. Some of these challenges are due to the intrinsic complexity of the subject matter — object-oriented concepts are tightly interrelated and appear in many combinations. The present work describes an approach to modeling educational domains and reports on the results for object-orientation. It analyzes the depende...

Modern programming languages such as Java facilitate the use of concurrent threads of control within computer applications. Considering concurrency is an important prerequisite for the adequate realization of object-oriented ideas, since real world objects usually operate in parallel. This brings up the requirement to be able to express concurrency issues already in design models, which precede...

Object-oriented concurrent programming is a methodology that seems to satisfy nowadays requirements for complex application development. Issues like inheritance anomalies or developing of object models that integrate in a natural way concurrent programming elements with object-oriented concepts was intensely analyzed in literature. Construction of a consistent modeling mechanism that ameliorate...
