JANUARY MEETING REPORT

Mr. Richard von Gemmingen of Virginia Transformer Corp. 
spoke on "Load Tap Changing Transformers". A total of 20 
persons (including guests) were present, some from Lexington and 
South Boston, and Mr. James Beall, Director of Region 3, graced 
the occasion by his presence.

Mr. Gemmingen commenced with an overview of the history of 
transmission of electricity and the early problems of voltage 
regulation. He went on to the techniques of De-energized tap-
changing and the associated problems.

After introducing the Load Tap-changing (LTC) concepts and 
alternatives available, he compared and contrasted different types 
of LTCs, such as resistive and reactive. He included explanations 
of the mechanical as well as electrical constructional features of 
the different devices. 

He went on to cover the different schemes of automatic control of 
LTCs to provide the desired voltage at the load terminals. He also 
spoke about the techniques of paralleling of LTCs. His lecture was 
amply illustrated with diagrams and photographs. Mr. von 
Gemmingen concluded the session by answering a number of 
questions from the floor.

PACE Patter

In the November Newsletter this column described a little of the 
annual PACE Conference. This month we will cover in more 
detail issues from the Career Policy Council.

In the mid 1990s career turbulence is in full flower with 
downsizing and outsourcing. Even with the unemployment of 
electrical and electronics engineers much less than in recent years 
every engineer, with or without a job, should be looking for the 
next job. It may be with your present employer or with a different 
one. The best way to maintain secure employment is by 
maintaining technical vitality. This means continuing education, 
technical and non-technical. In addition, you need to practice 
financial self-defense. Here you need to develop a saver's mind 
set, understand the costs of alternative sources of funds, and 
appreciate your own tolerance for risk. Maximum investment in a 
401(k) plan buying the right health care plan, avoiding excess tax 
withholding are a few of the steps to take.

There are many forces which individuals cannot control. The 
Workforce Committee follows activities in Washington and keeps 
the US IEEE member informed on such matters as economic 
security, employer-provided educational funding, immigration 
reform, independent contractors, service contracts, jobs training. 
Many of these issues were in the last Congress and will be under 
consideration again. Future trends in employment benefits are not 
necessarily to the benefit of the individual engineer. But these 
changes to move more of the risk and responsibility from the 
employer to the employee are a reality and if you are not informed 
you can make poor decisions regarding your financial future.

The factors which you can control are many, but not always easy 
to keep track of. A new tool to help all of us in managing our 
careers is the Career Asset Manager, (CAM). CAM provides 
information on career issues that can encourage and motivate you 
to do more planning. It also furnishes a means of keeping in one 
convenient form your complete work history and records of 
education, professional activities, community activities, and all 
other pertinent information. The most essential part of CAM is 
the CAMPlan which guides you step-by-step through developing 
your own Personal Development Plan. But it is no good if you 
don't have the Career Asset Manager and don't use it.

If you have questions about PACE or want to know more career 
activities of IEEE-USA or about the Career Asset Manager 
contact the section PACE chair, Daniel W. Jackson, 
d.jackson@ieee.org, (540) 774-0484.

Computer/Control/IES Chapter
February Meeting

"An Overview of Artificial Neural Networks"

David L. Livingston Virginia Western Community 
College

Tuesday, February 11 5:30 - 7:00 PM Cafeteria A
GE Industrial Systems 1501 Roanoke Boulevard Salem, VA

The field of Artificial Neural Networks (ANNs) is the study and 
application of mathematical models of neurons which are 
"coarsely" based on nerve and brain cell functions. ANNs are 
making the transition from basic research to commercial 
implementation and can be found in a wide variety of applications 
such as automated speech recognition, control systems, and 
financial forecasting.

This presentation will be an overview of ANNs. Topics will 
include a short history of ANN research, basic neuron models, 
various network paradigms, and the applications of ANNs to 
engineering problems. The application areas to be discussed will 
be selected based on audience interests.

David L. Livingston received the BSE, ME and Ph.D. degrees in 
electrical engineering from Old Dominion University in 1976, 
1978, and 1986, respectively. He worked as a Senior Associate 
and Staff Engineer in Intelligent Workstations at IBM, Endicott 
from 1981 to 1986. He then joined the faculty at Old Dominion 
University as an Assistant Professor of Electrical and Computer 
Engineering from 1986 to 1993. Dr. Livingston is currently the 
Program Head and an Associate Professor of 
Electrical/Electronics Engineering Technology in the 
Engineering/ Industrial Technology Division at Virginia Western 
Community College. He is the president of Integrated Intelligence, 
Inc. and is a licensed Professional Engineer in the Commonwealth 
of Virginia. He is a member of the IEEE Computer Society; the 
IEEE Systems, Man, and Cybernetics Society; Eta Kappa Nu; and 
the Virginia Academy of Science. His research interests include 
computational intelligence and embedded systems.

All IEEE Members and Guests are Welcome. There is no charge.

RESERVATIONS are appreciated! Call Dave Geer, 540-387-

January Meeting Report

On January 14, Tim Cribbs, Manager of Process Automation 
Engineering at GE Industrial Systems, discussed the mathematical 
models used in controlling the cold rolling of steel. His talk began 
with an overview of the steel making process and the part played 
by cold rolling. He then discussed the need for models in the 
control of cold rolling, to maximize productivity and minimize 
yield losses, quality defects, and commissioning time. 


At a typical cold mill, such as the 5-stand at USS Irvin works, 
coils weighing up to 16 tons are threaded at 100 feet per minute. 
After threading the mill accelerates at 500 fpm/sec to about 3500 
fpm. Before tail-out the mill decelerates to 150 fpm. Models are 
used to calculate the optimum thread and run setpoints for roll 
gaps, stand speeds, and roll bending forces under a number of 
constraints. These include the force and bending limits of the rolls 
and stands, power, torque, and speed limits of the motors and 
gears, tension limits imposed by the strip material and draft limits 
set by rolling physics.

Cold mill models use a number of formulas for these calculations. 

The gauge meter equation calculates the roll gap needed to 
achieve a target strip thickness. This equation takes into account 
the stretch of the mill housing under thousands of tons of force. 
The mass flow equation calculates relative speeds from entry and 
exit thicknesses. The deformation equation calculates roll force 
from entry and exit thicknesses, strip tensions, roll diameter and 
stiffness. Since these equations are inter-related, their solution 
requires multiple iterations to find the optimal answer given 
multiple constraints. In addition, many quantities such as material 
yield stress and roll to strip friction are only approximately 
known. An adaptive approach is used to account for variations in 
these quantities. 

Mr. Cribbs ended his talk with a discussion of future directions for 
model development. These include new, lower-cost platforms, 
more modern formulations for optimal solutions, and new 
technologies, such as neural networks and fuzzy logic.

A lively discussion followed the talk. About a dozen engineers 
attended.

Should you Consider the Temporary-Employment 
Option

(Reprint from IEEE-USA Impact)

You may be one of a growing number of engineers considering 
temporary employment as an alternative to taking a "regular" 
job with industry. If so, you should consider the rationale for 
becoming a "temp", the view of industry on hiring engineers on a 
temporary basis, and help that is available from IEEE-USA for 
members wishing to pursue this option.

The Employee Perspective
There are several personal situations that might make temporary 
employment the appropriate alternative to permanent 
employment: 

-obtaining specialized experience for career development;
in lieu of taking regular employment until the right career job 
is located; 

-after leaving one "permanent" job and prior to finding the 
next "permanent" job; and

-continuing activity in the profession after retirement, or to 
supplement retirement pay. 

Employer Perspective Fred Brauns, president of Lucent 
Technologies Services Co., provides some comments on 
temporary employment that should interest engineers 
contemplating this career option. 
IMPACT: Why does your company hire eng1neers on a 
temporary basis?
Brauns: We hire on a temporary basis to meet the fast build-up 
required at the beginning of a project; to eliminate expensive 
moves of employees for short-term projects; and to smooth out 
permanent employment roll fluctuations. 

I: What is your average length of employment of temporaries? 
B: Six to nine months. However, rehiring possibilities are very 
good or other projects.
I: What types of projects lend themselves to temporaries? 
B: Start-up and special short-term intense projects. Military 
projects, which have special security requirements, are least 
amenable to temporary employment, due to the length of time 
required to obtain clearances. 
I: Do you foresee industry using temporary employment for 
mainstream engineering requirements? 
B: Yes, I think industry will add some small percentage of their 
engineers as temporaries to hedge against the cyclical nature of 
staffing requirements. According to the first-quarter '96 issue of 
Staffing Industry Report by Staff Leasing, 2.2 million contract 
employees were on industry's payroll in late 1995. Approximately 
11 percent were technical professionals, compared to 5 percent in 
1993. 

IEEE-USA Can Help
According to Dick Riddle, Employment Assistance Committee 
chair, IEEE-USA offers these services for those seeking temporary 
employment: 

Employment-Assistance Information Package: This free 
information packet for unemployed, non student US IEEE

Is Your Membership Listing Current?

The IEEE membership data base is now in good shape. It is fairly 
reliable for purposes such as mailing this Newsletter to you, 
keeping your officers and Chapter Chairmen current with 
membership data, and as a platform underlying many IEEE 
services of potential benefit to you. However, there are still small 
errors which only you can correct. Some are simple typos, some 
are nearly epidemic. A case of the latter is an incorrect area code 
(703). A number of addresses are not current and, do you now 
have an e-mail address? Your technical affiliation should be 
checked, membership grade and status and, optionally, school 
information and degree(s). There is also considerable confusion 
over the two addresses, for those who list them. There is a 
"preferred" address to which all correspondence is normally sent, 
and another. The two are usually home and office addresses and 
you can choose the ordering. The non-preferred is generally an 
FYI item only.

So. Please take a minute to check your listing. You can look at the 
address on this mailing or your Spectrum mailer cover for the 
basic items, or if you wish, I can send you a copy of your current 
full listing (preferably via e-mail). Also, be sure to examine your 
listing when you renew your membership.
