Last year Duff Campbell (photo, right) joined the faculty in
a tenure-track mathematics position. His Ph.D. is from Boston
Univ. and he came to Hendrix from a position at West Point. His
primary interest is number theory but students would tell you he
is interested in everything. Duff is married to Beth Levi, a child
advocate lawyer. Their daughter Eva is a very active
Chris Mouron (photo, left) joins us this year as Dwayne Collins'
sabbatical replacement. Chris is a topologist with a Ph.D. from Texas
Tech and most recently he taught at the University of Delaware. Chris
and his wife Marisol have just moved to Conway.
Dwayne Collins will spend a sabbatical year working at Acxiom
Corporation in Conway and Bob Eslinger is serving as Interim Vice
President of Academic Affairs during the time it takes to replace
President Ann Die. David Sutherland was recently elected as a national
councillor of Pi Mu Epsilon.
This past summer we said goodbye to Lars Seme, '95, after
several years of exemplary teaching in the department. He recently
moved to Fort Smith where his wife Melissa is beginning a family
practice residency. Lars will teach at West Arkansas Community College
Last fall we moved back into a completely renovated Reynolds
Hall. All the windows are back in the building. In the photo above
you can see some of the east windows in Reynolds behind Bob Eslinger.
In the photo below you can see what the front of the building looks
like without the stairwells attached to the front of the old
The department space including seven faculty offices, two
classrooms, two computer labs, a server room, a library, and a kitchen
has all moved to the top floor. The offices have nice views of the
pecan courtyard in front of the building.
The classrooms are equipped with video projection equipment and
each desk has an internet connection and power source. The computer
labs—one for beginning mathematics and computer science students
and one for advanced computer science students—have new lab
furniture which promotes group lab work and are open 24 hours.
The library at the top of the stairs has comfortable furniture for
reading as well as tables and a blackboard.
Our physical surroundings are not the only changes in progress. As
soon as we settled into the building last year we began planning the
curriculum for the new semester calendar which begins Fall 2002.
Because the existing curriculum with a three-term calculus
sequence and overlapping two-term upper level mathematics courses
was designed for the term system, a complete overhaul was needed.
Changes include a two-semester calculus sequence and a required
discrete mathematics course. The curriculum is designed to prepare
students to begin research projects after the sophomore year.
Summer Research at Acxiom
This summer Dwayne Collins and several students continued their
research for Acxiom Corporation on binarization and subsequent OCRing
of telephone book text images. Previous work had resulted in several
approaches to binarizations of poor quality pages.
This summer's work focused on the final preparation of the
images for OCRing, getting the best results possible from batch
processing, and the parsing of the OCR record results into three or
While working on removing leaders (the line of periods separating
the address and telephone numbers) the group was confronted with
the problem of identifying what both local and global edges are
in such text images. Previous work using wavelets has turned to
curvelets and edgelets that handle "line" singularities far better
Seniors Tim McKuin and Elizabeth Fite, junior Jared Williams
and sophomore Geri Headrick have worked on the project. Dwayne will
continue this work during his sabbatical this year.
Carol Smith Schumacher, '82, gave the invited address at the 2001
Hendrix-Rhodes-Sewanee Symposium. Her talk entitled
at Infinity: Self-Similarity and Self-Reference in Mathematics
generated both excitement and many questions. Carol is a member of
the mathematics department at Kenyon College.
Lee Minor, '65, recently contributed several boxes of advanced math-
ematics books for our library. Lee is approaching retirement from
the mathematics department at Western Carolina University.
From left to right this year's graduates are Ben Goodwin (math),
Justin Hagemeier (cs), Anthony Nguyen (cs), Scott Bell (cs), Ben
Andrews (math), Aaron Tolman (cs), D. D. Davis (math) and Sara
Pennington (math). Not shown: Tim Hofer (math), Khiela Holmes
(math/psych) and Adrienne Wells (math/biol).
Hendrix mathematics and computer science students gave
presentations at five national and regional conferences this
Rhodes Scholar (and senior) Ben Goodwin presented his paper on
Cwatsets [www.cwatsets.org] at the winter meeting of the Mathematical
Association of American in New Orleans. Ben's work was done at
last summer's NSF-REU program at Rose-Hulman Institute. Senior Ben
Andrews and sophomore Dane Dormio gave presentations at the National
Conference on Undergraduate Research in Lexington, Kentucky. Ben's
talk was entitled “n-Person Duals where n>2” and Dane's talk
was entitled “Analysis of the Subtangent.” They were joined by
over forty other Hendrix students from other departments who made
presentations of their research projects. Sophomore Jared Williams
gave his presentation “Exploring Finite Time Blow-Up” at the
national Pi Mu Epsilon meeting this summer in Madison, Wisconsin. Jared
will spend fall term this coming year studying mathematics in
These four students were joined by seniors Adrienne Wells,
Aaron Tolman, Scott Bell, Anthony Nguyen and Tim Hofer at the
Hendrix-Rhodes-Sewanee Symposium which was held in our new facilities
Adrienne spoke about her summer work in biology using mathematical
wavelets in analyzing protein localization patterns and Tim
presented his senior project on using Hough transforms to de-skew
Computer Science students Aaron, Ben and Anthony presented their
on-line interactive game which utilized their senior project work
with distributed computing.
Finally, there were nine student presentations from Hendrix at
this year's Oklahoma-Arkansas section meeting of the MAA.
Besides Tim Hofer, Dane Dormio, Jared Williams, Ben Andrews and
Adrienne Wells, senior Sara Pennington, juniors Elizabeth Fite,
Karla Harper, Dagim Tilahun and Tim McKuin gave presenations. Tim,
Karla and Elizabeth reported on their Acxiom project with image
processing while Sara Pennington presented her senior project on
reversing numbers of acyclic digraphs. Dagim presented his work
involving series and products of pi.

base is inscribed in a circle of radius one. Then another circle is
inscribed in that triangle. Find (with explanation) the radius of the
smaller circle. E-mail your solutions to Ze'ev by December 1 to have
