and related devices at two locations in 
Blacksburg.

Dave Kingma has arranged a tour of the 
facility on North Main Street which 
houses the R & D operation as well as 
manufacturing. A number of engineers 
and technicians will serve as guides, 
answer questions, and discuss 
operations.

VMS Activities

Meeting Report

The 1999 Student Project Competition was 
held in the Hancock Atrium at Virginia 
Tech on April 15.   Nine teams involving 
20 undergraduate engineering students 
presented the results of their recent 
design efforts.  A wide array of topics were 
represented in the student projects.   The 
judges emphasized—more than once—that 
the high quality of the projects made their 
job of choosing prize winners a very 
difficult one.     
The prize winners were:

First Prize   Brian Gold for “A hybrid 
approach to inverse neural network control 
of nonlinear systems.”

Second Prize  Mark Hartman for “4 KA, 6 
KV emitter turn-off thyristor.”

Third Prize  Tom Boyer and Darius 
Parker for  “The design and use of a 
capacitor plate for the removal of adherent 
cells from culture Petri dishes.” 

All students received a certificate of 
participation in the competition.  The Prize 
Winners also received the following cash 
prizes:
        1st Prize       $350
        2nd Prize               $250
        3rd Prize               $150

        Congratulations go to John Bay, 
Virginia Tech ECE professor and VMS 
EXCOM member, for arranging this very 
successful Student Project Night.

Computer/Control/IES

May Meeting

Sunrayce Team Report

Every two years there is a race of full-
sized, human-driven, solar-powered 
vehicles called Sunrayce. Colleges and 
universities in North America 
participate in the rayce which is 
sponsored by the Department of 
Energy, General Motors, and EDS. 
This year the rayce is from 
Washington, D.C. to Orlando, Florida 
and will be coming through Virginia. A 
team from Virginia Western 
Community College is entered in the 
rayce and at the next meeting of the 
Computer, Controls and Industrial 
Electronics Societies, the team will 
give a progress report on its entry.

Time and Date:
        5:00 - 7:00 p.m.
        Tuesday, May 11, 1999
Place:
        S101, Student Center
        Virginia Western
        Community College

Directions: From I-81, take I-581 
South until it becomes Webber 
Parkway. Take the Colonial Avenue 
exit and make a left onto Colonial 
Avenue. About a mile down Colonial 
Avenue, turn left into the parking lot 
and then make an immediate right. 
Heading towards Webber Hall, the 
Student Center will be to the left of 
Webber. Make a U-turn and park in 
front of the Student Center.

Chapter Meeting Report:
At the April 6 meeting, Gary Magnus 
discussed Asynchronous Transfer Mode 
Technology. 

Summary
For the first time, AT&T data traffic 
exceeded voice traffic last year, and is 
growing at the rate of 2000 percent per 
year.  In this environment it is not 
surprising that digital technology is 
becoming more important for long haul 
communications. 

ATM differs from the older TDM systems 
in that fixed synchronous time slots are 
replaced by interleaved cells which can be 
assigned different priorities.  Thus voice 
cells, which require guaranteed maximum 
delay, can share the same physical channel 
with less time-critical data.  Large data 
packets are broken up into smaller ATM 
cells, each with its own priority and routing 
tags.  This prevents high priority cells from 
getting stuck in line behind a large, slow 
data packet. 

At the edge of the network, the User 
Network Interface uses 16 bits of the header 
for a virtual channel identifier, and eight for 
virtual path.  This allows switches to 
establish a dynamic path through the 
network that can change with time and the 
availability of physical facilities.   Four bits 
are used for payload type and cell loss 
priority, which together imply class of 
service.   The remaining header bits are 
used for flow control and error checking.
 
ATM interface servers provide different 
protocols for different traffic types.  One of 
these is the ATM Forum LAN Emulation, 
LANE.  This allows existing Ethernet and 
Token Ring traffic to run over ATM, 
transparent to the LAN devices.  LANE 
version 2 adds server-to-server 
communications, which allow enhanced 
services such as multi-cast.

A typical ATM network may contain video 
sources and displays using MPEG2 codecs, 
user workstations connected via a LANE 
Ethernet switch, and other sources of voice, 
video and data connected directly to an 
ATM multiplexer.  ATM offers the 
advantage of one network for all traffic, and 
is compatible with existing cable plant.  It 
simplifies network management and expects 
to have a long architectural life.

Gary finished his talk with a projection of 
the ATM market.  From about $3.6 billion 
in 1998, the market for services and 
equipment is expected to grow to $9.4 B by 
2001, with services accounting for an 
increasingly larger share.

Ten engineers from local industries 
attended the meeting.  Discussion 
was lively, and the number of probing 
questions indicated the keen audience 
interest.  Copies of the presentation 
are available.  Contact Dave Geer at 
d.geer@ieee.org or 387-7359.

IEEE TO AWARD $10,000 
SCHOLARSHIP AT INTEL 
SCIENCE FAIR
        
PISCATAWAY, NJ, 8 April 1999 -  IEEE 
Educational Activities announced today 
that, at the 1999 Intel International Science 
and Engineering Fair (ISEF) to be held 
from 2-8 May in Philadelphia, a $10,000 
scholarship will be awarded to the high-
school student whose project best shows 
"outstanding achievement in the research 
and presentation of engineering knowledge 
in electrical engineering and information 
technology or other IEEE fields of interest." 
This "IEEE Presidents' Scholarship" will be 
the single largest award given by an 
association at this year's fair.  The winner 
will receive $2,500 per year for each of the 
four years of undergraduate study, provided 
"an IEEE field of interest" remains his or 
her declared major.  In addition to the 
monetary award, the student will receive a 
plaque; a free IEEE Student Membership; 
and a CD-ROM and two videos that take an 
in-depth look at engineering careers. 

Beginning in 1950, the International 
Science and Engineering Fair is the only 
worldwide competition for students in the 
ninth through twelfth grades.  In 1997, Intel 
committed significant funds to become the 
title sponsor of this prestigious program.  
Considered by many in education to be the 
most enlightened program for science and 
engineering, INTEL ISEF provides for 
scholarships, internships, special awards, 
and travel grants totaling $2 million to be 
awarded to deserving students each year.

The IEEE has committed to providing a 
scholarship package at the next four Intel 
Fairs – a total of over $40,000.
