‘mDNS’ a hierarchical multicast session directory service architecture, which has been recently submitted to IETF editorial board for publication under Best Current Practice (BCP) track, allows administrative domains to join the global hierarchy incrementally. The global structure dynamically adapts to the changing topology. This paper describes the various failure scenarios in the proposed IET...

The upcoming Web 2.0 technologies change the aspects of eLearning fundamentally. The traditional paradigm of classroom teaching and homework learning will develop further towards sharing experiences and knowledge in word-wide social communities. Moreover, knowledge capturing in ambient environments gains more and more importance. These aspects characterize the so-called eLearning 2.0. This pape...

In this paper, we present a model to support decision-makers about where to locate safety barriers and mitigate the consequences of an accident triggering domino effects. Based on the features of an industrial area that may be affected by domino accidents, and knowing the characteristics of the safety barriers that can be installed to stall the fire propagation between installations, the decisi...

parameters such as future precipitation, temperature, snowfall, and runoff were modeled using precis regionalclimate modeling system in iran with the horizontal resolutions of 0.44×0.44°c in latitude and longitude under sresa2 and b2 scenarios. the dataset was based on hadam3p during the periods of 1961-1990 and 2071-2100. theoverall precipitation error of the model in the period of 1961-1990 w...

MANET is a special subset of wireless ad hoc network. Hence it is limited to power and other available resources (bandwidth, range). The paper mainly focuses on the effect and efficiency of protocol to handle node failure in the network. The failure of node results in the failure of link via that particular node and this may be due to the consequences of congestion, low energy levels and unpred...

This paper presents nonparametric predictive inference for system reliability following common-cause failures of components. It is assumed that a single failure event may lead to simultaneous failure of multiple components. Data consist of frequencies of such events involving particular numbers of components. These data are used to predict the number of components that will fail at the next fai...

Model-based scenario analysis with the ASM1 model was used to evaluate the effect of different process modifications on the biological nitrogen removal process for a specific case study (municipal wastewater treatment plant). Simulations showed that the construction of extra tank volume was needed to obtain the effluent standard of 15 mg N/l. However, the renovation scenarios resulting from a m...

This paper presents ongoing research in the field of application and further development of scenario-methods in strategic R&D processes. The core purpose of this study is to investigate how scientific and technological fields of innovation can be supported through participatory work with normative-narrative scenarios. The normative-narrative scenario approach focuses on a participatory communic...
