Rivier College Mathematics and Computer Science Lecture
Series
"Software Reliability Methods and Experience" Review
of the October 20-21 MIT Autonomous Sensing Conference
Presented by
David J. Dwyer
David J. Dwyer is a reliability engineer at BAE Systems,
Nashua, NH. He has a M.S. in Computer Science from Rivier
College (1999), M.S. in Electrical Engineering from
Northeastern University (1980), and B.S. in Physics from
Providence College (1963).
The presentation will address methodology in estimating
and projecting software reliability. It will help
academic audience to find answers to vital questions:
How reliable are industrial software products? Can
software reliability be measured exactly? New methods
are offered for estimating the test time required and
software failures to be corrected to reach reliability
goals of the test-and-fix programs.

Cryptography Through the Ages: A Layman's View
Humanities Series
Professor Higgs
developed a course on Computer Security, and became
fascinated by the rich and colorful history of the science
and art of cryptography -- the creation and transfer of
secret messages. This was surprising, because he
never considered himself
either a historian, or even a student of history. What
appealed to him was
the diversity of the subject: how many significant
historical events were impacted by cryptography, and the
amazing number of interesting people who were influential in
this history. You might be surprised at the number of
these people you are already familiar with from your own
knowledge of history, or from other disciplines. The
history of cryptography starts in ancient Egypt, progresses
through Greek and Roman wars, European city and nation
states, Mary Queen of Scots, two world wars, the
establishment of the National Security Agency, and the cold
war. It culminates in Quantum Cryptography, which is
based on the Quantum Theory and the theoretical possibility
of Quantum Computers, and promises theoretically unbreakable
ciphers. The focus of this presentation will be on the
historical events, and the people involved, including their
motivations, and the consequences of their actions; no
knowledge of computers or mathematics will be presumed.

Dr. Vladimir
Riabov is an Associate Professor at the Department of
Mathematics & Computer Science in Rivier College. He
specializes in networking technologies,
object-oriented system analysis and design, aeronautics, and
system simulation and modeling. He received a Ph.D. in
Mathematics and Physics from Moscow Institute of Physics &
Technology (1979) and a Master of Science in
Computer Information Systems from Southern New Hampshire
University (1998).
The presentation reviews the results of
systematic studies of modern networking-systems software. It
is shown that the number of unreliable complex code
functional modules correlates with the number of customer
requests, error-fixing submits, and the possible errors,
which have been estimated with McCabe and Halstead metrics.
It has been found that the major reduction of the code
complexity (based on the mathematical theory of graphs)
leads to significant reduction of errors and maintainability
efforts. Test planning and code coverage issues for embedded
networking systems are considered as well.
