As flourishing, productive open source software (OSS) communities mature, they have to introduce a variety of governance mechanisms to manage the participation of their members and to coordinate the launch of new releases. In contrast to other modes of governance of OSS communities, the Debian community introduced new mechanisms of informal administrative control based on a constitution, electe...

Onion routing protocols achieve low-latency anonymous communication on public networks. Up to date, many onion routing protocols have been proposed, such as Tor network, in order to implement the anonymous network connection in the public networks. Although the previous schemes’ multi-pass cryptographic circuit construction appears satisfactory, their circuit construction protocols have some dr...

The breakneck advance of multimedia capabilities and internet technologies offers an unprecedented opportunity to improve the quality of teaching and learning. Nowadays the use of multimedia resources and WWW-supported learning environments is a crucial issue in education and further education. Integrating visualization, animation, interactive experiments, sound and hotlinks to relevant interne...

film theoreticians such as tom gunning, miriam hansen, anne friedberg, leo charney, james donald and giuliana bruno emphasize on the simultaneity of the invention of the cinema and the formation of modern cities in the world. cinema, in effect, seems to have grown up in the context of modern cities. film’s evolution, stirring away from theatrical static space and the single boundary of primitiv...

This paper presents JECho, a Java-based communication infrastructure for collaborative high performance applications. JECho implements a publish/subscribe communication paradigm, permitting distributed concurrent sets of components to provide interactive service to collaborating end users via event channels. JECho’s eager handler concept allows individual event subscribers to dynamically tailor...

A speciic class of multimedia applications is expected to be of importance for future communication networks: Multi-Party Interactive Multimedia (MIM). Based on the isolation and characterization of MIM applications, concrete network support requirements are derived in this paper. The varying degree of connectivity, the vastly diierent sizes in terms of participants and the reliance on a guaran...

This paper introduces a new lightweight middleware for pervasive environments. This middleware abstracts network communications and provides service introspection and discovery using DNS-SD (DNS-based Service Discovery [1]). Services can declare simplex or duplex communication channels and variables. The middleware supports the low-latency, highbandwidth communications required in interactive p...
