The NATO wide area network provides secure IP services to NATO commands and agencies, and offers information exchange gateways to nations and coalition operations. The IP services support the NATO-wide deployment of core automated information systems (AIS), and the placement of specific functional area services (e.g., intelligence, logistics, C2IS for the services, etc.) at commands. To maintai...

The IPv4 addresses exhaustion demands a protocol transition from IPv4 to IPv6. The original transition technique, the dual stack, is not widely deployed yet and it demanded the creation of new transition techniques to extend the transition period. This work makes an experimental comparison of techniques that use dual stack with a limited IPv4 address. This limited address might be a RFC 1918 ad...

Cloud technology in a multi-enterprise, collaborative context is one of the most promising topics at IT-Supply Chain (SC) intersection. Cloud comes with well-proven advantages and cost savings; enabling collaboration and business intelligence. Cloud transition is still on-going with individual enterprise-level transitions. However, collaborative paradigm dictates that entire network well-being ...

We investigate the conditions that produce a phase transition from an ordered to a disordered state in a family of models of two-dimensional elements with a ferromagnetic-like interaction. This family is defined to contain under the same framework, among others, the XY-model and the Self-Driven Particles Model introduced by Vicsek et al. Each model is distinguished only by the rules that determ...

Recently, there has been increasing interest in data analysis for network structured data. The network structured data is represented the relation between one data and other data by graph structure. There are many network structured data such as social networks, biological networks in the real world. In this study, we will analysis the network structured data that has dynamic relation and compl...

Within a large-scale neuronal network model of macaque primary visual cortex, we examined how intrinsic dynamic fluctuations in synaptic currents modify the effect of strong recurrent excitation on orientation selectivity. Previously, we showed that, using a strong network inhibition countered by feedforward and recurrent excitation, the cortical model reproduced many observed properties of sim...

one for each variable. These transition functions map an input of the Boolean variables in X to a Boolean value (0 or 1). We call a Boolean vector x(t) = (x1(t), . . . , xn(t)) the state of the network at time t. Then, the next state of the network x(t+ 1) is calculated by applying all transition functions fi(x(t)). In a biological context, genes can be modeled as Boolean variables (active/expr...

This research-in-progress paper provides a preliminary explanation of an organization’s transitional journey as it moves from a hierarchical model of IT service provision towards a network one. What is important to understand is how the organization can safeguard that the value-producing qualities of IT service provision are maintained and enhanced throughout this transition. Using a single cas...

This paper discusses and brings together a detailed analysis of virtualization implemented at various levels of computing infrastructure, keeping in mind and providing detailed transition process adopted for transition from a classical to virtualized data center. It focuses on emerging trends or areas related with storage virtualization. Further, its various network level virtualization based i...

The possibility that a complex network can be brought down by attack on a single or a very few nodes through the process of cascading failures is of significant concern. Here we investigate a recent model for cascading failures in complex networks and uncover a phase-transition phenomenon in terms of the key parameter characterizing the node capacity. For parameter value below the phase-transit...
