Local Technical Discussions

    The Vietnamese Association for Computing, Engineering Technology and Science (VACETS) cordially invite you to the following monthly technical discussions

May 26th, 2001

Dr. Hoang Viet-Dung is currently with SETA Corporation in McLean, VA where he is performing system engineering work for the US Coast Guard. His presentation is from one of his projects at SETA and is entitled "AIS Transponder", which is about a GPS-based information system that will enable ships to learn about other ship positions as an alternative for radar detector. Dr. Hoang Viet-Dung was one of VACETS founders, and the 2nd VACETS President for the 1995-1996 term.
US Coast Guard Vessel Traffic Service (VTS) mission is to collect, process, and disseminate information on the marine operating environment and maritime vessel traffic; to provide the mariner with the information necessary to prevent or avoid collisions and groundings; and to provide recommendations or direction to vessel pilots. The National Dialog Group, made up of maritime and port communities, endorsed Automatic Information System (AIS) as a foundation for future VTS in April 1997. AIS will allow efficient exchange of navigational data between ships and between ships and shore stations, thereby improving safety of navigation. AIS will be used primarily for surveillance and safety of navigation purposes but can be used for other safety related communications.

The presentation will be on the technical aspects of AIS but will also review the VTS system and the Global Position System (GPS), the main component of AIS.

Is wireless Internet a hype? 
What are the potentials and pitfalls?

Dr. Hai Tran from the US General Accounting Office will present "Wireless Internet: Opportunities and Challenges." This is an updated version of the paper that he presented at the August VTIC2000 Conference in San Jose, California, taking into account recent development in the area of 3rd Generenation Cellular Telephony.

The marriage of web and internet is not only a happy ending, but also it had fuel the quest for a business-to-business (B2B) reality, and the XML was born. It has been two years now, and XML technology had grow quite a bit. We will take a closer look at the XML technology from the start, by examine the inherit traits of SGML. to its latest attractions of DOM and SAX, to see whether XML technology is just another high-tech buzz word. 

Mr. Anh Vuong from Cisco Systems, Inc. will present the Extensible Mark-up Language (XML), the currently de-facto standard language for Web development. He will briefly describe the XML language and then discuss its applications in many areas.

The Extensible Marked-up Language (XML), a subset of of the Standardized General Mark-up Language (SGML), can be viewed as the second-generation language for the Web. Its goal is to enable generic SGML to be served, received, and processed on the Web in the way that is now possible with HTML. XML has been designed for ease of implementation and for interoperability with both SGML and HTML.It is a computer language for describing information. XML promises finally to liberate information from proprietary file formats and make it possible for information to move amongmultiple programs on different types of computers without facing conversion programs and lost information. XML improves on the HTML approach to make the Web more useful, however, unlike HTML, XML is extensible in the sense that we can define our own tags. All XML-based languages share the same look and feel.

As information technology, especially the Internet, has changed the way we live and work, an understanding of the basic technologies and future trends will enable us to take advantage of technologies to improve our daily activities. This talk will cover current as well as emerging technologies. The presentation document is available here in PDF format.
Dr. Hung H. Nguyen from The Aerospace Corporation will discuss technologies and trends in telecommunications services. This tutorial is based on the paper he presented at the VACETS Technical International Conference (VTIC2000) in San Jose, California on August, 4-5, 2000.

The explosive demand for high-speed  residential Internet access has caused the telecommunications industry to race toward market dominance.
Current technologies for high-speed Internet access at home include xDSL & cable modem  for  wired  line, and LEO, MEO satellites & Local Multi-point Distribution  Service  (LMDS)  for  wireless communications. Each of these access  methodologies  has its own strength and limitation as shown in this tutorial  paper. Basic principles behind each of these technologies will be described in some details, and a view of the future technology trend will be presented along with relevant technology market forecast.
