We develop a dynamic model in which Operation Iraqi Freedom servicemembers incur a random amount of combat stress during each month of deployment, develop post-traumatic stress disorder (PTSD) if their cumulative stress exceeds a servicemember-specific threshold, and then develop symptoms for PTSD after an additional time lag. Using Department of Defense deployment data and Mental Health Adviso...

This memo specifies the extensions required of a host implementation of the Internet Protocol (IP) to support internetwork multicasting. This specification supersedes that given in RFC-966, and constitutes a proposed protocol standard for IP multicasting in the ARPA-Internet. The reader is directed to RFC-966 for a discussion of the motivation and rationale behind the multicasting extension spe...

Current approaches to supporting real-time communication allocate network resources either to individual connections, or to aggregates of connections. Resource sharing is a new approach that exploits known relationships between related connections to allow network resources to be shared between them without sacriic-ing well-deened guarantees. We present a fully distributed technique for using r...

1-In this paper, we examine the problem of address interworking that arises when two networks of the same type (that use the same addressing format) are interconnected by a different type of network (one that uses a different addressing format). Solutions to this problem fall broadly into four categories: (i) schemes that send address resolution messages when a call/packet arrives (" pull " inf...

Over the last few years, several nations around the world have set up Grids to share resources such as computers, data, and instruments to enable collaborative science, engineering, and business applications. These Grids follow a restricted organizational model wherein a Virtual Organization (VO) is created for a specific collaboration and all interactions such as resource sharing are limited t...

Emerging networking technologies are being introduced with their own management protocols for routing , resource reservation and signaling. This diversity restricts the interoperability among QOS-aware multi-media applications written for diierent networks. We present an approach for managing multiparty, multi-media sessions in a heterogeneous internetwork spanning multiple signaling domains. P...

Distinct social networks are interconnected via bridge users, who play thus a key role when crossing information is investigated in the context of Social Internetworking analysis. Unfortunately, not always users make their role of bridge explicit by specifying the so-called me edge (i.e., the edge connecting the accounts of the same user in two distinct social networks), missing thus a potentia...

Aims. The aim of this work is to study the structure of the magnetic field vector in the internetwork and search for the presence of small-scale loops. Methods. We invert 1.56 μm spectropolarimetric observations of internetwork regions at disc centre by applying the SIR code. This allows us to recover the atmospheric parameters that play a role in the formation of these spectral lines. We are m...

We consider real-time traffic in a heterogeneous internetworking environment with IP routers, MAC bridges, Hubs, Switched LANs etc. We assume that the current routing protocols remain unchanged. However, in this environment, in order to provide quality of service (QoS): bandwidth, delay, constantbounded jitter and no-loss due to congestion, we suggest a new flow control function called time-dri...
