Since the very early beginnings of parallel discrete event-driven simulation (PDES) research, numerous general-purpose PDES frameworks have been implemented. These frameworks can be roughly classified by the utilized modelling view (process-oriented vs. event-oriented), kind of parallelism (conservativeparallel, optimistic-parallel), and implementation language. Since the main motivation of par...

Identifying and documenting early crosscutting concerns, i.e. requirements-level crosscutting concerns, is critical. It improves traceability among requirements as well as between requirements and downstream artifacts, facilitates easier assessment of change impact, supports requirements evolution, enables the application of aspectorientation from the very start of the software lifecycle and pr...

Component Based Software Engineering (CBSE) and Aspect Oriented Programming (AOP) are two disciplines of software engineering, which have been generating a great deal of interest in recent years. From the CBSE point of view, the building of applications becomes a process of assembling independent and reusable software modules called components. However, the necessary dependencies description am...

Besides the conclusion of agreements about quality of service (QoS), one of the major prerequisites for a global service market are means to monitor the fulfillment of those agreements. From a user’s perspective, the time needed to complete a service transaction represents one of the most critical QoS parameters. As most electronic services are usually based on distributed applications, obvious...

Due to today’s rapidly changing corporate environments, business processes are increasingly subject to dynamic configuration and evolution. The evolution of new deployment architectures, as illustrated by the move towards mobile platforms and the Internet Of Services, and the introduction of new security regulations (imposed by national and international regulatory bodies, such as SOX or BASEL)...

Service-oriented architecture supports the definition and execution of complex business processes in a flexible and loosely-coupled way. A service-based application assembles the functionality provided by disparate, remote services in a seamless way. Since the architectural style prescribes that all features be provided remotely, these applications adapt to changes and new business needs by sel...

The main purpose of this paper is to provide a new point of view of Artiicial Neural Networks. Since the Object Oriented Modeling method provides a one-to-one mapping of the real world it is preferable for Artiicial Neural Networks which are derived from real biological Neural Networks. We start emphasizing the advantages of the Object Oriented approach over a functional point of view. We proce...

The Event-based Aspect-Oriented Programming model (EAOP) makes it possible to define pointcuts in terms of sequences of events emitted by the base program. The current formalization of the model relies on a monolithic entity, the monitor, which observes the execution of the base program and executes the actions associated to the matching pointcut. This model is not intrinsically sequential but ...

The classical view of a register-based abstract machine is a barrier for understanding the execution of object-oriented programs. We visualize program execution based on the object-oriented paradigm with its objects and the message flows between them. For this we propose a visualisation for intuitive understanding of object-oriented based program executions. Three dimensional animated illustrat...

Object–oriented views are important mechanisms that not only provide logical data independence, data hiding and security, but also are means of data integration, and simulating schema changes. Although several approaches to object–oriented views were proposed in scientific publications only a few commercial object– oriented databases support them. These approaches differ in functionality offere...
