Organizational and managerial theories of modularity applied to the design and production of complex artifacts are used to interpret the rise and success of Free/Open Source software methodologies and practices in software engineering. Strengths and risks of the adoption of a modular approach in software project management are introduced and are related to the achievements of various Free/Open ...

A property of term rewriting systems is modular if it is preserved under disjoint union. In the past few years the modularity of properties of term rewriting systems has been extensively studied. The first results in this direction were obtained by Toyama. In (Toyama, 1987a) he showed that confluence is a modular property (see Klop et al. (1994) for a simplified proof) and in (Toyama, 1987b) he...

Systolic architectures for inversion in Galois eld (GF (2)) are presented. The proposed inversion algorithm is a counter-free extended Euclidean algorithm, which results in simple circuit implementation for GF inversion. Additionally, the bit-parallel implementation proposed is shown to be C-testable. Testability and modularity make it suited to VLSI implementation.

in this paper, we construct two fuzzy sets using the notions of level subsets and strong level subsets of a given fuzzy set in a ring r. these fuzzy sets turn out to be identical and provide a universal construction of a fuzzy ideal generated by a given fuzzy set in a ring. using this construction and employing the technique of strong level subsets, we provide the shortest and direct fuzzy set ...
