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.
Abstract
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 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.
Abstract
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.
Abstract
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.
