Gravity drainage is one of the important recovery mechanisms in fractured carbonate and conventional reservoirs. It occurs due to density difference between the gas in fracture and the oil in matrix as well as in conventional tilted reservoirs. Oil phase will form films which are produced under gravity forces (film flow). Many gas injection experiments have been done on laboratory scales with d...

This paper addresses the business needs for key recovery as a countermeasure to the threat of losing potentially valuable information. Several requirements essential for a sound key recovery mechanism are described, and the applicability of two main classes of existing key recovery schemes to a corporate environment is examined. Different requirements are identified for key recovery mechanisms ...

Web service-based applications are widely used, which has inevitably led to the need for proper mechanisms for the web service paradigm that can provide sustainable and reliable execution flows. In this paper we revise recovery techniques in OWL-S and show how semantic annotations may ensure seamless web service provision in a sophisticated way, such as, exploiting the ontology-based descriptio...

In study of covert networks and destabilization strategies thereof, much attention has been paid to the task of locating and isolating key individuals within the organization. Metrics such as centrality, betweenness, cognitive load, and others, have all been used for that purpose. The isolation act was considered successful if it resulted in the network being separated into disconnected subpart...
