Most people in the world now live in cities. Urbanisation simultaneously isolates people from nature and contributes to biodiversity decline. As cities expand, suburban development and the road infrastructure to support them widens their impact on wildlife. Even so, urban communities, especially those on the peri-urban fringe, endeavour to support biodiversity through wildlife friendly gardens,...

Water vapor column (WVC) obtained by GOME-2 instrument (GDP-4.6 version) onboard MetOp-A satellite platform is compared against reference WVC values derived from GPS (Global Positioning System) instruments from 2007 to 2012 at 21 places located at Iberian Peninsula. The accuracy and precision of GOME-2 to estimate the WVC is studied for different Iberian Peninsula zones using the mean (MBE) and...

The k-vertex cover (k-VC) problem is to find a VC of cardinality no more than k on a given undirected graph, and the k-weighted VC (k-WVC) problem is to find a VC of a weight no more than k on a given vertex-weighted undirected graph. In this paper, we generalize the Buss reduction, an important kernelization technique for the k-VC problem, to the kWVC problem. We study its properties for the k...

This paper investigates the global connectivity of complex networks with random links. An expected communication graph weighted edges is used to model network. The notion vertex (WVC) introduced in literature as a generalization connectivity, known be effective measuring this type However, given computational complexity WVC, numerically efficient approximate measure for that more desirable. In ...

We applied a discourse analysis (DA) to the electronic chat room discussions of a 16-week, Internet-based section of a class in statistical methods in psychology. This analysis revealed that across the semester, several DA categories (e.g., total number of student comments) were correlated with final grade in the class. An additional analysis involving only the chat room discussion of Week 3 re...

Mobile Ad hoc Networks are characterized by multi-hop wireless links, without any infrastructure and frequent node mobility. A class of ant colony based routing protocols has recently gained attention because of their adaptability to the network changes. AntHocNet is ant colony based hybrid algorithm, which combines reactive path setup with proactive path probing, maintenance and improvement. M...
