Open Source Software (OSS) Projects are gaining popularity these days, and they become alternatives in building software system. Despite many failures in these projects, there are some success stories with one of the identified success factors is modularity. This paper presents the first quantitative software metrics to measure modularity level of Java-based OSS Projects called Modularity Index...

The development of Open Source Software (OSS) is fundamentally different from the proprietary software. In the OSS development scenario a single developer or group of developers writes the source code for the first version of the software and make it freely available over the internet. Then other developers are invited to contribute to the existing code for its next release. Making the source c...

On the basis of the national innovative enterprise’s evaluation index system, this paper established a new innovative enterprise evaluation indicator system; furthermore, it puts forward the evaluation method. It includes four aspects: the innovation input, the achievement transformation, digestion and absorption of imported technology, and innovative carrier construction. By applying the analy...

Habitat suitability index (HSI) models are traditionally used to evaluate habitat quality for wildlife at a local scale. Rarely have such models incorporated spatial relationships of habitat components. We introduce Landscape HSImodels, a new Microsoft Windowst (Microsoft, Redmond, WA)–based program that incorporates local habitat as well as landscape-scale attributes to evaluate habitats for 2...

In this paper, we first show that the logistic testing-effort function is practically acceptable/helpful for modeling software reliability growth and providing a reasonable description of resource consumption. Therefore, in addition to the exponential-shaped models, we will integrate the logistic testing-effort function into S-shaped model for further analysis. The model is designated as the Ya...

The reusability of assets is usually measured through reusability indices. However, these indices either do not synthesize their constituent metrics into an aggregate or they do not capture all facets of reusability, such as structural characteristics, external qualities, and their documentation. To alleviate these shortcomings, we introduce a reusability index (REI) as a synthesis of various s...

hansen et‎. ‎al.‎, ‎using the autographix software ‎package‎, ‎conjectured that the szeged index $sz(g)$ and the‎ ‎wiener index $w(g)$ of a connected bipartite graph $g$ with $n geq ‎4$ vertices and $m geq n$ edges‎, ‎obeys the relation‎ ‎$sz(g)-w(g) geq 4n-8$‎. ‎moreover‎, ‎this bound would be the best possible‎. ‎this paper offers a proof to this conjecture‎.
