To include multimedia streaming support in the web services domain, this paper presents a novel multimedia streaming web services framework for the transfer of streaming multimedia content. First, the framework includes an implementation of a query service for publishing(More)
I n this paper we present a new subdivision scheme that is shown to improve the performance of ray tracing surfaces of revolution over Kajiya 's classical work [8]. This is based on a monotonic interval partitioning of a generatrix of a surface of revolution. The algorithm has a search complexity upper bound of O( log (m n) ) f o r m ~ monotonic intervals(More)
This paper introduces the Gong system, an Internet-based voice board system designed primarily for language learners which includes special support for Cantonese. The Gong system is a client/server design which may be used to complement or, in some contexts, to replace face to face learning.

Web services provide efficient development and deployment of interoperable and reusable applications. Multimedia Web services is an implementation of multimedia applications within the Web services framework. However, current Web services standards are not sufficient to cater for multimedia streaming, the commonly used delivery method for large multimedia(More)
The Gong system has been developed for web based communication. It supports synchronous and asynchronous audio communication and can be embedded in other learning management systems. This paper discusses two novel features which are targeted at language learners using the system. The first is the ability to automatically index an audio recording. After the(More)
