We contend that the complexity of modern computer systems is caused by a dependency on a plethora of mechanisms that by their lack of coherence increase the cost of developing applications. By integrating these mechanisms we can reduce the complexity of the system and thereby achieve savings throughout product life cycles. From our experience in operating systems, programming languages and data...

Part of any engineering discipline is the use of systematic, repeatable and traceable processes, methods and procedures. Software architecture is a branch of the discipline of software engineering. However, software architecture design, documentation and evaluation is still lacking a sound basis of systematic, repeatable and traceable procedures. At present software architecture is still more o...

The in-process decisions made by designers strongly influence both the process of designing and the manifestation of the designed artifact. When improvement of designing is intended, the organization of the process and the content of the designers’ decisions have to be concurrently considered. Due to the inherited complexity, application of a computerbased simulation tool can be an effective so...

Designing virtual worlds as architecture considers the form and function of spatial virtual environments as an alternative kind of architectural design. This perspective can lead to a new way to organize and explore the Internet as a place. In this paper, we refer to this type of online environment as virtual architecture. Traditionally, virtual architecture refers to the 3D visual simulation o...

Multithreaded Object-Oriented Programming in concurrency environment using object-oriented technology is a complex activity. Programmers need to be aware of issues unrelated to their domain of problem, and are often unprepared for the challenges of the concurrent object-oriented programming brings. The interaction of their components becomes more complex, and makes it difficult to validate the ...

The M•CORE microRISC architecture has been developed to address the growing need for long battery life among today’s portable applications. In this paper, we present the architectural enhancements of the M3 processor, the successor to the original M•CORE M2 architecture. Specifically, we discuss the instruction buffer and pipeline enhancements, the branch prediction algorithm, branch folding fo...

In the current situation there is a lack of researches on measures of security processing and monitoring patient status information produced from rapid growth of infra within Medical environment. It is thus necessary to conduct such research on the medical care environment where there is a high demand for utilization of status information. This study suggests a solution of using RFID to gather ...

Today’s computational grids are using the standard IP routing functionality, that has basically remained unchanged for 2 decades, considering the network as a pure communication infrastructure. With the grid’s distributed system point of view, one might consider to extend the commodity Internet’s basic functionalities. Higher value functionalities can thus be offered to computational grids. In ...
