in this paper, changes of casson non-newtonian fluid velocity profile, for different distribution of porosity, have been investigated. for distribution of porosity, fixed, radial and exponential variations has been considered. for all three states, brinkman model has been used as momentum equation. since the casson fluid is a good model for blood, this analysis can be used in studying about cho...

Ensemble is a Group Communication System built at Cornell and the Hebrew Universities. It allows processes to create process groups in which scalable reliable fo-ordered multicast and point-to-point communication are supported. The system also supports other communication properties, such as multicast causal and total ordering, ow control, etc. This paper describes the security protocols and in...

Since the early 1980s, the research community has developed ever more sophisticated algorithms for the problem of energy disaggregation, but despite decades of research, there is still a dearth of applications with demonstrated value. In this work, we explore a question that is highly pertinent to this research community: how good does energy disaggregation need to be in order to infer characte...

distribution is one of the most important topics in industrial engineering and logistics and supply chain that all organizations are dealing with it in the upper echelons and are looking for the optimum distribution of resources and equipment among the echelon. generally, it is seen that organizations cannot have a good distribution if there is not a suitable criterion for the distribution of e...

A Delay Tolerant Network (DTN) is one where nodes can be highly mobile, with long message delay times forming dynamic and fragmented networks. Traditional centralised network security is difficult to implement in such a network, therefore distributed security solutions are more desirable in DTN implementations. Establishing effective trust in distributed systems with no centralised Public Key I...

There are several tools available that can be used to hold multimedia conference sessions within the Internet Multicast Backbone (MBone). Most of these tools provide means for public and private conferencing, but ooer no possibility to register participants of particular conference sessions, or to authenticate them accordingly. In a private conference session, every message is encrypted with a ...
