This paper presents a method for evaluating and selecting off-the-self software components to be reused in software development. The paper describes the main motivation and principles of the method and provides a provides a detailed description of it. The method has been tried out in two case studies and initial results of these studies are reported. * This work has been supported by the Hughes...

Independent component analysis (ICA) is an effective feature extraction tool for process monitoring. However, the conventional ICA-based process monitoring methods usually adopt noise-free ICA models and thus may perform unsatisfactorily under the adverse effects of the measurement noise. In this paper, a process monitoring method using a new noisy independent component analysis, referred to as...

This paper details our experience integrating a transaction manager component, called Pern with Process Weaver. Process Weaver's Petri-net based approach is excellent for explicitly modeling concurrent activities of cooperating agents, but there is no underlying mechanism for treating con icting actions of concurrent, independent agents. In addition, there is a need for advanced transaction sup...

specification of a component C, a set of components K relevant to C and called candidate solution SO, and a set of pre-selected components from SO, called solution SN. Sc(i) represents the map associated to the input value i defined in the domain of Sc. This map should provide a valid value on the output domain of Sc, i.e. there is no empty maps or invalid associations. A similar assumption is ...

In attempting to build a COTS integrated system, we can use several methods that typically pay attention to specify search criteria and goals to be met. Yet these methods often overlook some elements in the process such as fact-based decisions and teamwork, which might drive the process helping to increase the probability of success. In this position paper, we identify some features that we hav...

In this work, the efficiency, generality and applicability of new Bronsted acidic ionic liquid (BAIL) 1-methyl-3-(2-(sulfooxy)ethyl)-1H-imidazol-3-ium chloride {[Msei]Cl} as heterogeneous and green catalyst for organic transformations are studied. Herein, the following one-pot multi-component reactions in the presence of [Msei]Cl are investigated: (i) the synthesis of quinoxaline derivatives fr...

The past decade has assisted to a growing interest in reverse engineering and to the consequent proliferation of papers and experience reports about this subject from both academic and industrial environments. Many types of reverse engineering process components (i.e. methods, algorithms, techniques, procedures, processes model, etc.) have been proposed. To be able to reuse effectively the publ...

In spite of advancements in technology, the manufacturing of many small products and components continues to be labor intensive, and their assembly processes still rely on skill and craftsmanship. This paper describes operational problem solving through consultant-led intervention at one such manufacturer of watch dials, involving a combination of incremental and breakthrough improvements leadi...

We have been working on the MARVEL rule-based development environment (RBDE) for several years [9, 7], and are currently in the process of scaling up to supporting cooperation among multiple users working together on large projects [1]. This line of research led us to breaking up the previous single user MARVEL 2.6 implementation into the two main pieces of multiple user MARVEL 3.0: the clients...

An important issue in a component-based software development process is the supply source of mature, reliable, adaptable, and maintainable components. We define as component mining the deliberate, organised, and automated process of extracting reusable components from an existing rich software base and present a pattern language used for mining components from programs that are typically execut...
