Some Current I2 Applications at MTU

1
Some Current I2 Applicationsat MTU

• Internet Videoconferencing
• Video Streaming
• Remote Microscopy

Internet Videoconferencing

• Just like the telephone, expect you can see who
  you are talking to.
• You can talk to more than one person at a time.
• It is not a video broadcast.

3
Two types of Videoconferencing

• Traditional -ISDN
• Use in special room
• High installation cost
• High use cost
• Schedule in advance
• Professional operator
• H.320 standard

• Internet
• Use anywhere
• Low installation cost
• Now usage cost
• Impromptu
• Do-It-yourself
• H.323 standard

Videoconferencing Systems

• Software based
• Slow, not very satisfactory
• NetMeeting, CuSee Me
• Hardware based plug into PC USB
• Newest approach Polycom ViaVideo
• Hardware based PCI card
• Zydacron cards (MTU has this)
• Hardware based Polycom Viewstation

Video Streaming

• Video Streaming delivers live and on-demand
  audio/video programs streamed over the Internet.
  To stream video movies or audio broadcast, a
  server constantly feeds video packets (or
  streams) to an end point (or client). This is
  different than past video technologies where the
  user waited until the entire clip downloaded to
  their machine before watching it. Streaming video
  gives the expectation of just-in-time, real-time
  delivery.

Video Streaming

• An adequate streaming video service depends on
  the quality of the video, bandwidth available,
  and target machine speed.
• MTU supports both QuickTime and RealMedia, with
  continued research on MPEG2 to offer
  higher-quality video over Internet2.

Video Streaming

• httpwebmedia.mtu.edu
• RealMedia, QuickTime, Media Player, etc ( players
  are free and run on most OS)
• Applications
• Distance learning, special events, live campus
  radio stations, sports, etc.

Remote Microscopy

• The scanning electron microscope (SEM) has become
  a key instrument for observing characteristics of
  both natural and man-made materials.
• Provides the ability to observe specimens at very
  high magnifications (e.g. 100,000x) while
  maintaining an extraordinary depth of field.
• Allows for a chemical analysis of an
  approximately one cubic micron volume of a
  specimen (1 micron 1 millionth of a meter).

Remote Microscopy

• The application of this instrument has become
  widespread throughout the life sciences and
  physical sciences. Application of the SEM to a
  given science is limited primarily by access.
• Many universities or public agencies do not have
  the financial resources required to purchase and
  support an SEM which can cost as much as 500,000
  and requires a skilled operator.
• Researchers have developed cooperative
  arrangements with extramural laboratories for
  access to an SEM.

17
Remote Microscopy

• New SEMs are PC based and Internet compatible.
  This has spawned a whole new approach to SEM
  access called remote microscopy. A user sends
  their specimen to the SEM laboratory and phones
  the lab to insert their specimen when they are
  ready to perform microscopy.
• The researcher controls the SEM from their own PC
  at their own site. The user is billed for access
  time but does not have to incur travel expenses
  to perform the research. The researcher controls
  the instrument guaranteeing that the data
  acquired is what they desired.

Remote Microscopy

• MTU is purchasing new SEM instruments
• New instruments will not need sample preparation
• Contact information is in your folders
