First generation wireless systems, which primarily provide analog voice service, are widely in use worldwide. Second generation systems support digital voice/data traffic; some of these systems are already deployed or undergoing deployment. Third generation wireless networks will ultimately carry multimedia traffic that are characterized by combination of different informaion streams of diverse nature (e.g., voice, video, image, data). Some of the salient features of multimedia applications are high speed and changing bit rates (periodic and bursty arrivals), several virtual connections over the same access, synchronization of different information streams, and various service/deliveIy requirements (QoS).

Virtual Observatory (VO) is a collection of interoperating data archives and software tools. Taking advantages of the latest information technologies, it aims to provide a data-intensively online research environment for astronomers all around the world. A large number of high-qualified astronomical software packages and libraries are powerful and easy of use, and have been widely used by astronomers for many years. Integrating those toolkits into the VO system is a necessary and important task for the VO developers.

With Windows Vista, Microsoft shifted from the development path of Windows XP wide open to tampering with zero reaction, and has integrated an anti-piracy infrastructure into the platform. In direct correlation with the Windows Genuine Advantage and the Activation mechanisms, Windows Vista will be able to detect and blacklist non-genuine product keys, crack attempts, and identify the expiration of the initial 30-day grace period. The operating system will react to all by moving first into a non-genuine state and then into Reduced Functionality Mode.

The 1,000,000 plant specimens stored at the National Herbarium of New South Wales are a major resource used by scientific botanists to confirm the identification of plants. The Digital Imaging project will provide an Internet- accessible electronic image bank of the herbarium collections. These data will be managed in the NSW collections database system. The images will be accessible through PlantNET on the RBG website. The first phase of the project will include all NSW native (including rare and endangered) and weedy species, subspecies and varieties. This web based database will provide a resource that can be used to confirm plant identifications by the community. This project will link images and enhance the continuing development of the EucaLink, WattleWeb and other similar projects that are part of PlantNet. It is also closely coordinated with the national Australia’s Virtual Herbarium (AVH) project being undertaken by all herbaria in Australia.

A number of new geospatial viewing tools from major players in the Internet industry have recently appeared on the scene and are taking the geospatial world by storm. Google,Yahoo, Microsoft, and Amazon have all released web-based mapping tools in the recent past, and collectively these new players to the industry have raised the bar for Internet mapping. Although their functional capabilities don’t provide anything we haven’t seen in web offerings from traditional GIS vendors, their emergence has been significant in that they have managed to capture a wider audience. Google, in particular, has emerged as the leader of this pack with it’s recently released Google Maps product which provides a slick, highly responsive visual interface built using AJAX technologies along with detailed street and aerial imagery data, and an open API allowing customization of the map output including the ability to add application specific data to the map.
