Dear Biomch-L readers,

The xposting below serves a dual purpose: FIRST, to mention the GOPHER
interactive information retrieval service, which is complementary to
anonymous ftp, WAIS, and the various NETFIND/NETINFO facilities recently
mentioned on this list, and SECOND, to mention the existence of a new
and promising signal processing / modelling method: WAVELETS, with a
rather close relationship to SPLINES.

Enjoy! hjw

Wavelet Information available through Gopher

The Gopher server of the University of South Carolina Department of
Mathematics has been extended to hold a collection of wavelet information.
Currently, this information includes papers, programs, source code, and
USENET messages pertaining to wavelet theory, as well as an interactive
search service for wavelet references and archives of the Wavelet Digest.

1. What is Gopher?

Gopher is a distributed-information system developed at the University of
Minnesota. It consists of both information servers at institutions spanning
the globe, and client programs used by individuals to access and navigate
this data. Gopher has been designed to be easy-to-use; it is menu-based,
and most information can be retrieved using only the cursor keys. Another
major feature of Gopher is the seamless access it brings to distributed
information located on remote Gopher, anonymous FTP, WAIS, WWW, or other
services. For more information on Gopher, check out the Gopher Information
items on most Gopher services, the information via anonymous FTP on
boombox.micro.umn.edu in directory /pub/gopher, or the alt.gopher and
comp.infosystems.gopher USENET newsgroups and the Frequently Asked Questions
posting on Gopher in news.answers.

2. Accessing the USC-Math Gopher service.

Gopher is growing rapidly in popularity on the Internet; as a result, there
is a good chance your local computer system may already have a client
compiled. If your site already possesses a Gopher client (check with your
system administrator), type

gopher bigcheese.math.scarolina.edu

and you should find yourself at the USC Dept. of Mathematics Gopher
service; use the cursor keys to select "Wavelet information" on the
menu (currently item 14), and explore the information offerings of
the service as you please; the cursor keys can be used to navigate
the system.

If your site *doesn't* currently possess a Gopher client, the wavelet Gopher
service may be anonymously accessed using the Telnet program. Type

telnet consultant.micro.umn.edu

and login as "gopher" (case is important). After logging in, you will find
yourself at the Gopher server of the University of Minnesota. To reach the
University of South Carolina Gopher server, choose "Other Gopher and
Information Servers" from the main menu, then servers in "North America."
Choose the "University of South Carolina, Dept. of Mathematics" from the
list of servers; (currently number 71, but this changes as new
servers become available). If you have difficulties reaching Gopher with the
above instructions, ask your local system administrator for assistance, or
contact Brygg Ullmer as ullmer@math.scarolina.edu.

If you would like to obtain the Gopher client for installation upon your
system, it is available via anonymous FTP from boombox.micro.umn.edu in
directory /pub/gopher. Versions of Gopher are currently available for Unix,
VMS, NeXT, Macintosh, IBM PC-compatible, and other computer systems.

3. The Wavelet Reference Database.

A feature of the wavelet information on the USC Gopher service is a database
of wavelet references. Currently the references are accessible in two
forms. Individual reference lists from various individuals or papers are
available in their original formats; however, more powerful access is
provided through the local WAIS search engine. With the WAIS facilities,
references and abstracts (when available) are processed to yield a master
full-text index for all citations available, regardless of format. This
index can be queried using either keywords or full natural-language
requests. Documents containing the specified words are ranked on the
basis keyword proximity, frequency, and other factors, and listed in order
of the strength of search matches.

4. If you have references or papers to contribute...

If you have a reference list to literature concerning wavelets that you'd be
willing to contribute, we'd be happy to add it to our database and credit
you as its source. Mail any such lists with the subject "submit" to
wavelet@math.scarolina.edu; BibTeX format is preferable but not necessary.
If abstracts for your references are readily available, please include those
as well... this will allow more accurate selection of articles and will be
more useful to people viewing references. Additionally, if you have papers
related to wavelet theory which are online, particularly if these papers are
available via anonymous FTP, feel free to submit these as well, and they
will be made publically available through the service as storage space
permits. If your papers are available via anonymous FTP, please send the
location of the papers rather than the papers themselves.

5. Other features of the USC-Math Gopher Service.

In addition to the wavelet information available on the above-described
Gopher service, a variety of information of more general interest is
available. Phone directories and libraries of universities around the
world are integrated into the service, as well as collections of technical
reports, electronic books from Project Gutenberg and the Online Book
Initiative, and a variety of other electronic texts. Throughpoints to
major NSF, NASA, NOAA, and other governmental databases are also integrated
into the system, as well as Frequently Asked Questions lists, search
for USENET newsgroup archives, and other bodies of information.

6. Credits

Gopher has been developed by the University of Minnesota.

WAIS is a freely-distributed product of Thinking Machine Corporation.

Contributions to the wavelet reference list have currently been received
from Akram Aldroubi, Bjorn Jawerth, Christopher Koenigsberg,
Juhana Kouhia (from a USENET posting), Eero Simoncelli
(from a USENET posting), Wim Sweldens, and Brygg Ullmer.

The USC-Math Gopher service was developed and is maintained by Brygg Ullmer.
