Necessity for a Productive software has been culminating and Object-Oriented Design technique is providing solution to this as it is the most powerful mechanism for developing proficient software systems. It is helpful not only in declining the cost but also in the development of high quality software systems. Software developers require accurate metrics for developing efficient software system...

There is an ever-increasing interest in investigating dynamics in timevarying graphs (TVGs). Nevertheless, so far, the notion of centrality in TVG scenarios usually refers to metrics that assess the relative importance of nodes along the temporal evolution of the dynamic complex network. For some TVG scenarios, however, more important than identifying the central nodes under a given node centra...

Metrics have long been used in software engineering to measure, evaluate, and improve software products and processes. Many metrics have been developed and their subsequent use in different settings has led to varying levels of success. Software architecture is a discipline in which few metrics have been applied, a surprising fact given the important role that software architecture plays in sof...

Although it is generally recognized that global biodiversity is declining, few studies have examined long-term changes in multiple biodiversity dimensions simultaneously. In this study, we quantified and compared temporal changes in the abundance, taxonomic diversity, functional diversity, and phylogenetic diversity of bird assemblages, using roadside monitoring data of the North American Breed...

BACKGROUND To examine the association between the American Heart Association's 7 metrics of ideal cardiovascular health (ICH) and the presence of subclinical coronary atherosclerosis as assessed by coronary artery calcification (CAC) using electron-beam computed tomography. METHODS AND RESULTS This study is a cross-sectional analysis of data obtained on 3121 male and female patients evaluated...

In this paper, we study the class of of C3-like Finsler metrics which contains the class of semi-C-reducible Finsler metric. We find a condition on C3-like metrics under which the notions of Landsberg curvature and mean Landsberg curvature are equivalent.

in this paper the general relatively isotropic l -curvature finsler metrics are studied. it isshown that on constant relatively landsberg spaces, the concepts of weakly landsbergian, landsbergianand generalized landsbergian metrics are equivalent. some necessary conditions for a relativelyisotropic l -curvature finsler metric to be a riemannian metric are also found.

various human pressures are affecting the aquatic biocoenosis in running waters of iran - similar to many other areas of the world. overall 190 sites, 88 at salmonid (44 reference/impacted respectively) and 102 at cyprinid (50 reference/52 impacted) streams of the southern caspian sea basin were investigated in terms of human pressures present and the related impact on fish assemblages. in tota...
