Over the last decade many research groups have been developing reengineering environments. However, many design decisions such as support for multiple models, incremental loading of information, tool integration, entity grouping, and their impacts on the underlying meta-model and resulting environment have remained implicit. Based on the experience accumulated while developing the Moose reengin...

In our reengineering project, we regard architecture modeling and reengineering techniques of telecommunication systems. Our work concerns analysis and restructuring of such systems, including the re-design and re-implementation. As telecommunication systems are often planned and modeled using state machines, it seems reasonable to analyze the systems also on the more abstract representation le...

Recently several robust control designs have been proposed to the load-frequency control (LFC) problem. However, the importance and difficulties in the selection of weighting functions of these approaches and the pole-zero cancellation phenomenon associated with it produces closed loop poles. Also the order of robust controllers is as high as the plant. This gives rise to complex structure of s...

Almost every computer software system is bound to be reengineered for at least maintenance purposes at some point and hence reengineering is as important as any other phase in a system’s lifecycle. It is important that both the original development method and the reengineering approach are chosen to minimise maintenance costs. Since users often discover that they want features in their system t...

Effects of double packaging (combinational use of aerobic and vacuum conditions) and antioxidants on physicochemical properties in irradiated restructured chicken rolls were determined. Chicken breast treated with antioxidants (none, sesamol+a-tocopherol) was used to process restructured chicken breast rolls. The sliced rolls were vacuum, aerobic, or double packaged (vacuum for 7 d then aerobic...

The paper analyses the reengineering concept as it comes from software engineering and management fields. We combine two viewpoints and apply them to solve a problem of reengineering of a distance study system, in general, and the unit of learning, in particular. We propose a framework for reengineering of unit of learning, based on general model of software reengineering, and present a case st...

The most important factor in maintaining Web Engineering Information Systems WEIS lifecycle is the reengineering process that in most cases is due to serious problems and hence high maintenance costs; this process must be closely monitored by audit procedures. Once the WEIS was put into production, the maintenance and reengineering considerations started, and the Information System Risk and Qua...

Current research in software reengineering offers a great amount of tools specialized on certain reengineering tasks. The definition of a powerful common interchange format is a key issue to provide interoperability between tools. This paper discusses aspects of data interchange formats for exchanging reengineering related data and proposes a graphbased format to exchange both data and applicat...

The experience of reengineering a Computerized Numerical Control, CNC, is presented. In the reengineering, several new functionalities and the upgrading towards the object-oriented were included. The reengineering process was maintained under control in order to complete the process within the deadline with success. Some technical and economical lessons learned that can be useful for helping th...
