There are many benefits to implementing a service oriented architecture (SOA), such as the efficiency gained in utilizing shared resources, the flexibility of composing systems with model-based constructs, and the ability to incorporate centralized policies and oversight mechanisms. However, as services proliferate and the applications that consume them get more complex, the need to better mana...

This study sought to identify the important constructs associated with service innovation and elucidate the role of information and communication technology in the innovation management. These phenomena are examined from the perspectives of technology as well as soft innovation. A review of the literature related to service innovation, cultural production, and service systems led to the develop...

The Real-time Channel Administration Protocol (RCAP) provides control and administration services for the Tenet real-time protocol suite, a connection-oriented suite of network and transport layer protocols for realtime communication. RCAP performs per-channel reservation of network resources based on worst-case analysis to provide hard guarantees on delay, jitter, and packet loss bounds. It us...

The collaborative platform on clustering applications for governments consists of six large-scale systems, including the clustering Government Internet portal system, clustering public-mailboxes collaboration system, clustering government affairs portal system, clustering emergency information collaboration system, clustering office automation collaboration system, and clustering messages colla...

In this paper the operation of multiple reservoirs by the utilization of analysis method of the system dynamics is considering and this analysis method is based on the feedback and object oriented events. The goal of this research is presentation of a new method by utilization of system dynamicity technique for simulation of the reservoir. This software is a product of Ventana Company and the e...

This paper describes a powerful integrated development environment that covers all steps of the development of an object-oriented real-time application from initial design to the final evaluation. The system consists of a set of integrated tools for modeling, simulation, implementation, instrumentation, monitoring, and visualization that all work on the same o-o system model. As all steps of cr...

In this paper, we present an empirical analysis of the object-oriented database concurrency control mechanism named OC as specified in Olsen (1995). OC is a lock-based mechanism that is designed specifically to take advantage of the object-oriented database model as specified in Kim (1990). The OC strategy is two-phased and uses eight different kinds of locks. The eight types of locks are Inten...

In this paper we propose a new integrated programming environment for teaching the object-oriented programming paradigm. The environment is based on the microworld approach to teaching programming and the programming language of Karel++. Its main features are: a series of e-lessons, a special kind of structure editor, run-time error detection, program animation and recordability of students’ ac...

Large numbers of classes, complex inheritance and containment graphs, and diverse patterns of dynamic interaction all contribute to difficulties in understanding, reusing, debugging, and tuning large object-oriented systems. These difficulties may have a significant impact on the usefulness of such systems. Tools that help in understanding the contents and behaviour of an object-oriented enviro...
