This project aims to classify the optional practical training comments using a naive Bayes classifier. We demonstrate the effectiveness of the naive Bayes approach and further enhance its performance using a simplified form of an expectation maximisation algorithm. We explore how sentiments change over time, and also provide preliminary results that help in(More)
A Mobile Ad-Hoc Network (MANET) is a group of wireless, mobile, battery-powered clients and servers that autonomously form temporary networks. Three data communication modes can be provided in a MANET, data broadcast, data query, and peer-to-peer messaging. The objective of this research is to develop a MANET data communication technique, BDAS (Broadcast(More)

In this paper, we address the problem of analyzing an evolving application and presenting the synopsis of changes, which can be recursively drilled down in an interactive manner.(More)
Despite advances in standards-based commercial-off-the-shelf (COTS) technologies, key challenges must be addressed before mission-critical distributed real-time and embedded (DRE) systems can be developed effectively and productively using COTS component-based software. For example, developers of DRE systems continue to use ad hoc means to select and(More)
