 ErrorCorrecting Codes and Matrices over Finite Fields
David Carlson received his Ph.D. at the University of Wisconsin; he
has been on the faculty at San Diego State since 1982. His
published research has been in matrix theory, but he has always had
an interest in applications of his subject. In the past few years,
his special interests have broadened to include issues in the
teaching of linear algebra and of calculus.
Gary J. Sherman, Department of Mathematics

 Lower division: Develop the essence of BCH codes in the
context of a specific example (a doubleerror correcting code
in binary 15space is constructed and an error correction
algorithm is developed).
 Upper division: ReedSolomon codes for bursterror correction.
Gary Sherman has been at RoseHulman since receiving his Ph.D. from
Indiana University in 1971. During his tenure at RoseHulman, he
has taught (receiving several teaching awards), done research
(mostly finite group theory), consulted (operations research for
Milliken Textile), and administered (chair for six years).
Professor Sherman developed Rose Hulman's Theorodrome (an upper
division computer classroomlaboratory with special emphasis on
applied and theoretical algebra and discrete mathematics) and
directs an NSF Research Experience for Undergraduates program at
RoseHulman.

 Some Applications of Mathematics in Telecommunications
(Traffic theory, reliability, computeraided engineering and
multicriterion optimization)
Mike Tortorella (Ph.D., Purdue University) spent two years on the
faculty at the University of WisconsinMilwaukee before joining
Bell Labs in 1975 as a member of the technical staff. Originally
trained in classical applied mathematics (boundary value problems,
inverse scattering, nonlinear functional analysis), he has worked
at Bell Labs with numerous applications of stochastic processes in
telecommunications problems, including teletraffic, economics, and
reliability. A Distinguished Member of the Technical Staff since
1984, he is currently manager of the Design for Reliability
Processes and Technologies Group at Bell Labs and an Associate
Editor of Naval Research Logistics.

 How Can You Listen to a CDROM with Scratches on It?
(coding theory)
Daniel Zwillinger (Ph.D., California Institute of Technology) has
a broad background in applied mathematics. He taught at Rensselaer
Polytechnic Institute for four years, has worked for Exxon and
MITRE, and has held temporary appointments at Sandia Labs, JPL,
IDA, and DMA. He has published three reference books in
mathematics. Currently, he directs an applied mathematical
consulting business and manages a book reference series for
CRC.
