data types as reusable software components: the case for twin ADTS by K. Sikkel and J.C. van Wet Abstract data types (ADTs) are typical candidates for reusable software components. An important, although generally undecidable, question is how to design ADTs so as to make them truly reusable. In this paper, we present an elaborate example, showing that the most abstract ADT is not necessarily th...

This paper reports our experience on exploiting the object-oriented and real-time features of Ada95 to support the development of a reusable software fault tolerance testbed. The testbed is a hardware and software platform for the creation of software fault tolerance systems from reusable components and provides a fault-injection environment for evaluating their effectiveness. The reusable comp...

While many reusable methods assume that developers will eventually become motivated to search for reusable components, few have addressed the issue of identifying when in the development process potentially reusable information exists. In this paper, a method is introduced that embeds reusable information in a process model that is customized to the specific needs of development efforts. By reu...

This paper describes the MATHESIS Ontology, which is part of the MATHESIS project that aims at the development of an intelligent authoring environment for reusable model-tracing math tutors. The purpose of the ontology is to provide a semantic and therefore inspectable and reusable representation of the declarative and procedural authoring knowledge necessary for the development of a model-trac...

This paper reports on an industrial case study in a large Norwegian Oil and Gas company (StatoilHydro ASA) involving a reusable Java-class framework and an application that uses that framework. We analyzed software changes from three releases of the framework and the application. On the basis of our analysis of the data, we found that perfective and corrective changes account for the majority o...

classes are also the basis of object-oriented frameworks [3]. In this approach, a high-level design is written as a program that consists only of abstract classes, and the design is applied to particular situations by providing implementations of the abstract classes. Frameworks can be seen as providing reusable context code. Just as reusable macros enable macro libraries, and reusable procedur...

This article introduces the notion of agreement patterns, which provide a framework for modelling reusable problem solution descriptions for agreement fulfilment. In particular, the Provider Selection pattern has been identified for modelling the common problem of selecting a provider by a service consumer. The article presents the pattern structure as well as the reusable domain model and cogn...

A fuzzy extractor (Dodis et al., Eurocrypt 2004) is a pair of procedures that turns a noisy secret into a uniformly distributed key R. To eliminate noise, the generation procedure takes as input an enrollment value ω and outputsR and a helper string P that enables further reproduction ofR from some close reading ω′. Boyen highlighted the need for reusable fuzzy extractors (CCS 2004) that remain...

A Fuzzy Extractor (Dodis et al., Eurocrypt 2004) is a two-step protocol that turns a noisy secret into a uniformly distributed key R. To eliminate noise, the generation procedure takes as input an enrollment value ω and outputsR and a helper string P that enables further reproduction ofR from some close reading ω′. Boyen highlighted the need for reusable fuzzy extractors (CCS 2004) that remain ...

For developing reliable software, it is important to reuse existing software components. Reusable components are not only their developer’s own, but also Open Source Software. In addition, there are hosting services to support developing and sharing open source software recently. As a result, it has been easier to search or distribute reusable components. When reusing or distributing reusable c...
