"This talk will describe a facility in Santa Cruz, California that enables astronomers to conduct observations using the Keck 10-meter Telescopes remotely via Internet-2 (The two Keck Telescopes are currently the world's largest optical/infrared telescopes and are located at an elevation of 4,200 meters on the summit of Mauna Kea on the island of Hawaii). The California facility is targeted towards short-duration observing runs which now comprise roughly half of all scheduled science runs on the Keck Telescopes. Keck technical staff in Hawaii support remote observers on the

mainland via video conferencing and collaborative software tools. Advantages and disadvantages of remote operation from California versus Hawaii are explored. A plan is presented for a backup communications path to protect against failure of the primary network. Alternative software models for remote operation are explored, and recent operational results described. During this talk, we plan to establish a multi-point videoconferencing link via Internet-2 between the conference site in Chile, our remote observing facility in California, and the Keck observatory facilities in Hawaii. We plan to link up with the astronomer as he performs observations with the Keck-1 Telescope."

"The presentation will discuss CANARIE, CA*net 3 and several examples in detail of customer owned/controlled dark fibre networks in Canada. In particular the economics, management and rationale for such networks will be discussed. concluding with thoughts on the future of customer empowered networks".

Conference 6
"Visualization, Internet2 and the Earth Sciences"

"Technology and infrastructure are now at a nexus that enables researchers to visualize data in near real-time. At the same time the economics of computer hardware give lecturers the ability to deploy advanced visualization hardware in the classroom. The next question is "Now what?"

This talk will showcase immersive visualizations of Seismological, Geophysical, Space Physics and Geologic data using desktop computers and an Immersadesk. A new display device developed by the EVL called the GeoWall will be introduced and it's future impact on collaborative research and education will be discussed".

Conference 2
"Virtual Reality and Teleinmersion in Medicine"

Download presentation.
( PowerPoint 97 - Document HTML)


"The common perception of Internet2 is that it is all about bandwidth or "a big pipe." In the healthcare domain there are very few applications that require huge amounts of bandwidth. In fact, the realm of virtual reality and tele-immersion is one of the few exceptions to the rule for healthcare. More important to healthcare is the issue of Quality of Service. In the Internet2 world this refers to guaranteed bandwidth and

packet delivery time windows. One of the goals of the healthcare working group is to extend the definition of Quantity of Service to include built-in security, data integrity, and authentication. This presentation will highlight some of the quality of Service issues for healthcare and demonstrate some of the work of the Virtual Reality in Medicine Laboratory of the University of Illinois at Chicago".

Plenaria 5
"High Speed Wireless Technology"

"The rapid convergence of ubiquitous wireless access and broadband internet surfing creates insatiable demand for high bit rate wireless access. However, the capacity of a cellular system is interference limited and cannot be increased by increasing transmitted power since doing so increases interference also. Furthermore, increasing system capacity utilizing additional radio spectrum is also impractical. The electromagnetic spectrum has become a scarce and very expensive resource with licenses valued in the tens of billions of dollars. It is also not viable to increase capacity by reducing cell size below today's micro cells of about 1000 ft.
Increasing spectral efficiency with multiple transmit and multiple receive antennas opens a new dimension, space, offering exceedingly high bit rates without increasing transmitted power or bandwidth allocation. In this talk, I will describe the basic principles behind space-time wireless systems, their performance, experimental results and near term impact on 3G wireless systems".

Conference 4
"Colaborative Design and Virtual Environments in Architecture"

"Despite of our most advanced compression techniques digital image is still challenging our abilities to develop more relevant bandwidths. Because of the massive use of graphic, the speed of the conventional digital nets has had troubles to satisfy Architecture. Plus the demand of professional architects for documentation, the environment where they take the decisions is particularly demanding. The architect makes use not only of the drawings; also he uses the
 
models and verbal and non-verbal language at the moment of presenting and discussing he's ideas of design. If we could understand that the architects needs a multimedia environment in where they could cooperate with other designers which are geographically dispersed, the demand of bandwidth should be extremely demanding. In this presentation we are going to analyze different experiences developed in the Texas A&M University, which where directed to satisfy the requirements of architects in a virtual environment, specifically design for that purpose. The name of that environment is The Infinity Room".
