Abstract:

The subject of legacy telecommunication systems is often overlooked in the pursuit of technological advancement, yet somehow the result is often less than graceful with end users left walking a tightrope between technology they are familiar with, and the evolving replacement systems.

Abstract:

Cloud computing is a paradigm which has changed the way organizations develop, manage, and deploy their applications. Most of the resources are available at low costs in this technology and it creates new opportunities for organizations to move their existing applications to the cloud for modernization. But this modernization also comes at a price. The authors present a model-driven approach to address the challenges in application modernization and focus on the application migration to cloud. Most of the cloud applications are very specific to a particular vendor's features or services. The proposed methodology addresses the challenge of vendor lock-in also. The authors present their theoretical details and experience with two pilot projects where they have applied the proposed approach.

Abstract:

The paper presents data oriented and process oriented models of legacy systems. It discusses the details of systems development and evolution models mainly aiming at an ongoing reengineering of legacy systems into supply chain systems. It proposes few strategies for reengineering of both data oriented model and process oriented models. The legacy systems often miss automatic interfaces to supply chain systems, so the article presents a strategy focusing on automatic update of data of the system. Likewise, the article also presents a strategy for process reengineering in order to integrate these legacy systems into supply chain systems. Finally, a legacy system is envisioned as a comprehensive mix of both data and process oriented, while proposing a gradual ongoing reengineering of both data structures and process methods.

Abstract:

This paper gives a brief historical survey of fluid power systems. It shows that many current applications can be traced to ideas embedded in the pioneering work of Bramah and later contributors. The demand for high dynamic performance has been satisfied by advances in components and the fusion of technologies. A central theme is the importance of developing effective tools for system synthesis. It is shown that research in progress will ensure a future for fluid power in the twenty-first century.

Abstract:

Amount of legacy systems in early stages are fall behind multi-core ages, and these legacy systems were designed for single processor which can not expand the computing power of the multi-core hardware. In this paper, we employ aspect oriented programming technology and design the crosscutting concerns for the potentially parallelizable software components of legacy systems. We propose a new multi-core programming model which can change the single thread of legacy systems into multi-threads for multi-core hardware platform without revising the source code of legacy systems. The proposed method can enhance the performance of software and utilization of hardware.

Full text

Abstract:

The recent battle reported from Washington about proposed national testing program does not tell the most important political story about high stakes tests. Politically popular school accountability systems in many states already revolve around statistical results of testing with high-stakes environments. The future of high stakes tests thus does not depend on what happens on Capitol Hill. Rather, the existence of tests depends largely on the political culture of published test results. Most critics of high-stakes testing do not talk about that culture, however. They typically focus on the practice legacy of testing, the ways in which testing creates perverse incentives against good teaching. More important may be the political legacy, or how testing defines legitimate discussion about school politics. The consequence of statistical accountability systems will be the narrowing of purpose for schools, impatience with reform, and the continuing erosion of political support for publicly funded schools. Dissent from the high-stakes accountability regime that has developed around standardized testing, including proposals for professionalism and performance assessment, commonly fails to consider these political legacies. Alternatives to standardized testing which do not also connect schooling with the public at large will not be politically viable.

Abstract:

This paper summarizes our experiences in using computer-supported methods to develop a software architecture to support the re-engineering of the Janus Combat Simulation System. We have analyzed the Janus FORTRAN source code, interviewed Janus domain experts, developed an object-oriented architecture for the Janus Combat Simulation subsystem, and validated the architecture with an executable prototype. In this paper, we propose methods to facilitate the evolution of the software component of these systems by recovering the behavior of the systems using systematic methods, and illustrate their use in the context of the Janus System.
