Software rearchitecting is the process of obtaining a documented architecture for an existing system. There are many software rearchitecting frameworks which are based upon different concepts and context-related issues for a specific application or programming language, such as Rigi, Ciao, SPOOL, and Symphony, and Software Rearchitecting Action Framework (SRAF). Most of the frameworks focus on ...

BACKGROUND Given increasing pressures for hazardous chemical replacement, there is growing interest in alternatives assessment to avoid substituting a toxic chemical with another of equal or greater concern. Alternatives assessment is a process for identifying, comparing, and selecting safer alternatives to chemicals of concern (including those used in materials, processes, or technologies) on ...

Frameworks or problem solving environments that support application development form an active area of research. The Multidisciplinary Optimization Branch at NASA Langley Research Center is investigating frameworks for supporting multidisciplinary analysis and optimization research. The Branch has generated a list of framework requirements, based on the experience gained from the Framework for ...

Requirements engineering (RE) tools are software tools which provide automated assistance during the RE process. The need for automated support varies in different projects. RE-tool support could clearly be useful if an organisation deals with requirements specifications containing many requirements which need to evolve over time. However, the mainstream RE practice relies on office tools (e.g....

In this paper we describe the range of values that can be taken by the fractional weak discrepancy of a poset and characterize semiorders in terms of these values. In [6], we defined the fractional weak discrepancy wdF (P ) of a poset P = (V,≺) to be the minimum nonnegative k for which there exists a function f : V → R satisfying (1) if a ≺ b then f(a) + 1 ≤ f(b) and (2) if a ‖ b then |f(a) − f...

In this paper, principles and existing feature selection methods for classifying and clustering data be introduced. To that end, categorizing frameworks for finding selected subsets, namely, search-based and non-search based procedures as well as evaluation criteria and data mining tasks are discussed. In the following, a platform is developed as an intermediate step toward developing an intell...

Evaluation frameworks have been presented that suggest layered evaluation of adaptive systems along two dimensions: (i) the software development cycle, and (ii) the component of the adaptive system that shall be looked at. We argue that a third dimension is crucial: the question whether an evaluation should take place in the lab or in the field. We present a refined systematization of evaluatio...

Selecting an appropriate process modeling language forms an important task for organizations engaging in business process management initiatives. A plethora of process modeling languages has been developed over the last decades, leading to a need for rigorous theory to assist in the evaluation and comparison of the capabilities of these languages. While substantial academic progress in the area...
