We prove that the Gromov-Witten moduli space of a compact symplectic manifold carries a unique virtual fundamental class that satisfies certain naturality conditions. The theorem also applies to moduli spaces of relative J-holomorphic maps. The virtual fundamental class is constructed using only Gromov-type perturbations; it is based on introducing stabilizing divisors and systematically applyi...

The purposes of this research were to develop online museum for packaging using Virtual Reality. This museum was to be considered as a learning instruction resource outside class to solve the issue of insufficient time in class. The instructors encouraged learners to build up the knowledge by themselves via active learning activities. The sampling group for this study consisted of 40 second yea...

An I-Room is an “intelligent room” which can act as a knowledge aid to support collaborative meetings, especially those involving sense-making about the current context, planning and considering options, and decision-making. It can be used to provide an Emergency Response Virtual Collaboration Centre in a Virtual World. The I-Room will provide a generic technology basis for a wide range of pote...

Internet Relay Chat (IRC) systems have become an increasingly popular social medium in the cyberspace. The main goal of the Multimedia Communication System (MMC) is to extend the functionality of traditional text based IRCs systems by adding such multimedia technologies as voice, digital sketching and a shared browser to create a tool for educational purposes. The idea is to create a virtual st...
