Green space is important for the maintenance of the ecological dimension of a sustainable urban landscape. Therefore, in order to figure out the relationship between the greening of urban parks and bird diversity, we used 5 avian ecological diversity indexes, such as Species richness, Abundance, ShannonWeiner diversity index, Evenness, and Margalef’s richness indices, to evaluate the functional...

The performance of cooperative diversity with opportunistic beamforming is analyzed in rayleigh fading channels. Cooperative communication is viewed as a method for increasing diversity gain and reducing end to end path loss. The use of relays can create a virtual antenna array so that it allows users to exploit the advantages of multiple input multiple output (MIMO) techniques. In this paper w...

The current inter-domain routing in the Internet, which is based on BGP-4, does not allow for the use of multiple paths, but rather restricts the routing to a single path for each destination prefix. This fact is especially unfortunate considering the vast route diversity which is inherently present in the global Internet graph. Therefore, we propose Inter-Domain Route Diversity (IDRD) as an ov...

Workgroup assignment problems commonly appear in various settings including international business schools. Especially if diverse people, like students, need to be divided into workgroups one may seek environments where diversity is fostered by generating heterogeneous workgroups. We study a problem of workgroups diversity maximization, i.e., the problem of building workgroups with the goal of ...

We study the consequences of introducing individual nonconformity in social interactions, based on Axelrod’s model for the dissemination of culture. A constraint on the number of situations in which interaction may take place is introduced in order to lift the unavoidable homogeneity present in the final configurations arising in Axelrod’s related models. The inclusion of this constraint leads ...
