This study presents the options for source-segregation and selective collection of recyclable waste fractions for Cetinje, Montenegro, with the aim of meeting the European Union 50% waste recycling target in 2023, and extending collection and disposal system that builds on the existing strengths of the city. To this end, three options were considered: (1) source separation and separate collecti...

Hierarchical cross-certification fits well within large organizations that want their root CA to have direct control over all subordinate CAs. However, both Peer-to-Peer and Bridge CA cross-certification models suits better than the hierarchical one with organizations where a certain level of flexibility is needed to form and revoke trust relationships with other organizations as changing polic...

This paper analyses different alternatives for solid waste management that can be implemented to enable the targets required by the European Landfill and Packaging and Packaging Waste Directives to be achieved in the Valencian Community, on the east coast of Spain. The methodology applied to evaluate the environmental performance of each alternative is Life Cycle Assessment (LCA). The analysis ...

The integration of IMS networks will enable telecom operators to evolve in a manner transparent to the incessant demand for the multimedia services. However the QoS management mechanisms defined for IMS networks are considered poor in oversight and monitoring real-time services. Moreover the eTOM Framework includes the scenarios of monitoring service delivery that enable real-time tracking serv...

Handling highly dynamic scenarios as they arise in mass casualty incident (MCI) situations requires lots of information about the situation and an extremely flexible IT infrastructure that can assist in managing the incident. We show a combination of technologies from different fields of research that have focused on the support of the strategic and tactical level in such situations. We describ...

When data are limited it is difficult for conservation managers to assess alternative management scenarios and make decisions. The natterjack toad (Bufo calamita) is declining at the edges of its distribution range in Europe and little is known about its current distribution and abundance in Poland. Although different landscape management plans for central Poland exist, it is unclear to what ex...

Recent geochemical and hydrological findings show that the water quality of the base flow of the Lower Jordan River, between the Sea of Galilee and the Dead Sea, is dependent upon the ratio between surface water flow and groundwater discharge. Using water quality data, mass-balance calculations, and actual flow-rate measurements, possible management scenarios for the Lower Jordan River and thei...

Data outsourcing is emerging today as a successful paradigm allowing individuals and organizations to exploit external servers for storing and distributing data. While trusted to properly manage the data, external servers are often not authorized to read them, therefore requiring data to be encrypted. In such a context, the application of an access control policy requires different data to be e...
