Free/Libre/Open Source Software (FLOSS) practitioners and developers are typically also users of their own systems: as a result, traditional software engineering (SE) processes (e.g., the requirements and design phases), take less time to articulate and negotiate among FLOSS developers. Design and requirements are kept more as informal knowledge, rather than formally described and assessed. Thi...

Smart phones with Internet capability are growing in popularity, due to many of their useful capabilities. Among other handy features of smart phones, Instant Messaging (IM) is very popular due to the level of convenience it provides in interpersonal communications. As the usage of IM on smart phone is increasing rapidly, it is important to take measures in advance from forensic standpoint fore...

For Internet-centric usage, the number of SIP-required standards for presence and IM and audio/video communications can be drastically smaller than what has been published by using only the rendezvous and session-initiation capabilities of SIP. The simplification is achieved by avoiding the emulation of telephony and its model of the intelligent network. ’Simple SIP’ relies on powerful computin...

Inspection of physical memory allows digital investigators to retrieve evidence otherwise inaccessible when analyzing other storage media. In this paper, we analyze in-memory communication records produced by web-based instant messaging and email applications. Our results show that, in spite of the heterogeneity of data formats specific to each application, communication records can be represen...

In China, the competition in the IM market is very intense and there are over 10 IM product...

This study investigated ways to attain mutual, reciprocal awareness of recipient’s availability status in Instant Messaging (IM) applications. For that purpose we designed, implemented and tested a prototype of an IM system named DoBother. The analysis of the quantitative and qualitative results showed that displaying status indication in the chat box encouraged participants to show more respec...

We describe a Web-services based conversational agent architecture that combines logical inferences from the WordNet knowledge base and Web content extraction using Google’s Web-search API. Our agents interact with users over the Web, as voice-enabled animated characters and can reach wireless devices through Instant Messenger protocol adapters.

Research indicates that using a cell phone to talk or text while maneuvering a vehicle impairs driving performance. However, few published studies directly compare the distracting effects of texting using a hands-free (i.e., speech-based interface) versus handheld cell phone, which is an important issue for legislation, automotive interface design and driving safety training. This study compare...

Over the past decade, classic client side applications with Model-View-Controller (MVC) architecture haven’t changed much but become more complex. In this paper, we present an approach of building desktop applications with Web Services in an explicit message-based MVC paradigm. By integrating with our publish/subscribe messaging middleware, it makes SVG browser (a Microsoft PowerPoint like clie...

The US National Fusion Collaboratory (NFC) project has been exploring a variety of computer and network technologies to develop a persistent, efficient, reliable and convenient collaborative environment for magnetic fusion research. One goal is to enhance remote and collocated team collaboration by integrating collaboration software tools into control room operations as well as with data analys...
