Developing global citizens has become a priority in nursing education worldwide. Since limited number of students participate face-to-face academic exchanges with host institution, innovative educational approaches to bring the world are needed. Virtual (VGE) experiences offer opportunities for from around interact and learn each other without packing suitcase. While VGE's can improve learning ...

along with the advent of recent communicative technologies, new cyber social networks have been emerged as the most influential line of interaction. this is a new world free from many of constraints and limitations of the physical world. it lacks weather, gravity, and geographical features; therefore it does not require addressing many of structures and necessities of the real world. in the vir...

As the virtualization of resources becomes popular, the scheduling problem of batch jobs on virtual machines requires new approaches. The dynamic and sharing aspects of virtual machines introduce unique challenges and complexity for the scheduling problems of batch jobs. In this paper, we propose a new set of metrics, called potential capacity (PC) and equilibrium capacity (EC), of resources th...

In virtual cellular network (VCN), proposed for highspeed mobile communications, the signal transmitted from a mobile terminal is received by some wireless ports distributed in each virtual cell and relayed to the central port that acts as a gateway to the core network. In this paper, we apply the multi-route MHMRC diversity in order to decrease the transmit power and increase the multi-hop lin...

The use of virtualization technologies to increase the capacity and utilization of laboratory resources is widely used in classroom environments using several workstation based virtualization products. These virtual networks are often “air gapped” to prevent the inadvertent release of malware. This implementation however requires users to be in the classroom. A novel extension on this concept i...

Virtual Private Networks (VPN) and link sharing are cost effective way of realizing corporate intranets. Corporate intranets will increasingly have to provide Integrated Services for voice and multimedia traffic. Although packet scheduling algorithms can be used to implement Integrated Services in link sharing [1] and virtual private networks [2], their statistical multiplexing gains are limite...

virtual water adds a new dimension to crop trades and provides a new way of thinking about water scarcity. a systematic analysis of virtual water flows requires integration of all critical drivers of virtual water flows under a single consistent framework. the aim of this study was to assess virtual water flows related to trades of grain crops (wheat, corn, rice, and coarse cereals) and their i...

The method is put to the test with the development of a model to address situations where capacity is overburdened and potential for propagation of the resultant delay though later flights is possible via flight dependencies. The resultant model includes primitive representations of principal air traffic system attributes, namely system capacity, demand, airline schedules and strategy, and airc...
