In this work we introduce the design and internal workings of the Iris decentralized messaging framework. Iris takes a midway approach between the two prevalent messaging middleware models: the centralized one represented by the AMQP family and the socket queuing one represented by ZeroMQ; by turning towards peer-to-peer overlays as the internal transport for message distribution and delivery. ...

This paper describes the difficult problem of seamless messaging in heterogeneous communication environments and the design of cooperative agents to address the problem. The seamless messaging agents include coarse-grained agents such as user agents, message transfer agents, server agents (for resources such as speech recognition and generation), application agents (interfacing to mail applicat...

background: intensity of depressive symptoms could be exacerbated due to the paucity of appropriate treatments. we assessed the effectiveness of bibliotherapy and text messaging, which aimed at amelioration of patient’s behavior and consciousness, which could lead to suicide prevention. methods: this was a randomized clinical trial implemented in rural health centers of isfahan district (iran)....

P2P [Peer-to-Peer] systems use messaging for communication amongst peers, and therefore the efficiency of messaging is a key concern for any P2P environment; particularly environments with a potentially large number of peers. One of popular representations of a P2P system is JXTA, which uses XML-based messaging. In this paper, we describe how the use of XML compression can increase efficiency o...

The Extensible Messaging and Presence Protocol (XMPP) is an application profile of the Extensible Markup Language (XML) that enables the near-real-time exchange of structured yet extensible data between any two or more network entities. This document defines XMPP’s core protocol methods: setup and teardown of XML streams, channel encryption, authentication, error handling, and communication pri...

We contrast the requirements and performance of messaging systems in parallel and distributed systems emphasizing the importance of the five orders of magnitude difference in network hardware latencies in the two cases. We note the importance of messaging in Grid and Web service applications in building the integrated system and the architectural advantages of a message based compared to a conn...

In the Public Health White Paper “Healthy Lives, Healthy People” (2010), the UK Government emphasised using incentives and “nudging” to encourage positive, healthy behaviour changes. However, there is little evidence that nudging is effective, in particular for increasing physical activity. We have created a platform to research the effectiveness of health-related behaviour change interventions...

This paper introduces a domain-specific modeling language (DSL) for modeling application-level network protocols. Application-level messages may be expressed in object-oriented general-purpose programming languages as classes. Instances of these classes can be sent through the network with the help of a customized serialization process. However, protocols have several special characteristics th...

Despite the extreme diversity of Web applications, one can find similarities among them. This paper proposes an answer to the question of knowing whether it is possible to conceptually represent different Web applications in a common manner such that they can generically be integrated in other Web applications. The 3A model developed at EPFL in the framework of the European PALETTE project is u...
