DOE FOSSIL ENERGY HBCU INTERNSHIP PROGRAM WEB DEVELOPMENT USING HOMESITE
Courtney Fields Computer Science and Mathematics, Department of Math and
Computer Science, Elizabeth City State University
The first generation of static World Wide Web Pages is gradually giving
way to dynamic sites with animation, backgrounds, images, and other
applets which enhances an enjoyable homepage. There is also a steadily
rising number of elements in which users can interact within their
particiular creation of a homepage. This has become possible through new
technologies which enables web browsers to create, implement, and
product a homepage.
When it comes to technology, designing a homepage is time-consuming,
requires sufficient planning, specialized knowledge, and patience. Most
researchers learn how to create a homepage by using a software package
called HTML. Hypertext Markup Language (HTML) is a language that is used
on the World Wide Wibe to create web pages. In conjuction with HTML is
another package known as HomeSite. HomeSite is a development tool
specialized for homepage beginners. HomeSite provides the user the
ability to quickly learn, easily understand, and create a productive yet
informative website. HomeSite also connects with HTML and the web
through a special HTML device known as the CSE Validator. This allows
developers to have a HTML syntax checker and and external/internal
browser for the Internet.

BAMBOO: A PORTABLE SYSTEM FOR DYNAMICALLY EXTENSIBLE, REAL-TIME,
NETWORKED, VIRTUAL ENVIRONMENTS
Alicia Jones, Department of Math and Computer Science, Elizabeth City
State University
One of the goals at the Naval Research Laboratory's Virtual Reality lab
is to be able to have various people in a virtual environment and be
able to have a system load and unload information upon demand. Bamboo
has gained the interest of the VR Lab because they would like to use
this software with one of their ongoing projects. As I continue my
research in the department, I am expected to be able to use Bamboo and
show all of its capabilities.
Bamboo is a distributed, dynamically extensible virtual reality toolkit
that is being developed by Kent Watsen and Mike Zyda at the naval
Postgraduate School in Monterey, CA. It came out in May 1997. Bamboo is
named after the plant which is compromised to many interwired shoots and
roots. It is designed to facilitate the research and development of
virtual environment applications of multiple platforms. Bamboo is to be
able to access files on an as needed basis in a virtual environment.
Bamboo supports callbacks, threads and event handling. All three
mechanisms work together so modules can be loaded and unloaded upon
demand. The callback is one of the most fundamental mechanisms in all of
Bamboo.

TEMPORAL RESPONSES OF THE MAIZE CATALASES TO LOW TEMPERATURE
Tanya Granger, Department of Biology, Elizabeth City State University
Catalase is a primary antioxidant enzyme that removes hydrogen peroxide
(H2O2) and prevents reactive oxygen species from forming. It is this
enzyme that exhibits temporal differences in response to environmental
factors. In this experiment the plant Zea mays(maize) was used. In maize,
three unlinked structural catalse genes, Cat1, Cat2, and Cat3, encode a
catalse isozyme(Cat-1, Cat-2, and Cat-3). The expression of specific
catalase isozymes is important and critical against oxidative stress.
Four maize lines(W64A, WA10B, WI9D, and WDN7-1) were observed to see if
the catalase isozymes were induced or reduced in an environment of 4
degrees Celsius. W64A is the maize Standard inbread line which expresses
all three cat genes. WA10B expresses Cat2 gene. WI9D maize line
expresses Cat3 null and WDN7-1 a homozygous null line expresses Cat2 and
Cat3.
Low temperature affects plants at all stages of their development. The
chilling stress at 4 degrees Celsius helps detect changes in the pattern
of catalse isozyme expression through the course of normal
postgermination development. The four maize lines were post imbition at
two and five dats. Due to the growth of the germinating seed, this
helped the increase of catalase. This truly helped detect if chilling
stress has an effect on catalase. The scutella and axes of germinated
seeds were studied. The catalse genes were expressed primarily in these
parts of the tissues. The effect of catalase to low temperatures also
helped detect levels of RNA. This experiment determined if the chilling
stress on catalase reduces or induces the catalase activity.

MULTIMEDIA AUTHORING WITH AUTHORWARE
J. Williams, J. Powell, and Angela Mizzele. Department of Math and
Computer Science, Elizabeth City State University.
The N.E.R.T. Multimedia Group explored the world of interactive
presentations through Authorware Software. First, the group learned
Authorware basics by using the Macromedia Authorware 4 Authorized
Hands-On Training Booklet. Once the students had mastered the basic
concept of Authorware, they created their own story boards for an
original presentation. The students presentation was called, "Authorware:
From Us to You". With this presentation, the students explained what
Authorware is and its educational value.
The primary audience was made up of fellow students who have not yet
been exposed to this type of multimedia software. Students in the
multimedia group also learned how to insert pictures, graphics, sounds
and text into their original Authorware presentation. A field trip to
the local United States Coast Guard Base allowed students to view
several Authorware presentations created by staff at the USCG Media
Center. While at the USCG, the students received other ideas and
suggestions from Authorware uses that enchanced the presentation.
The second stage of this project will involve providing support for an
Interactive Multimedia Physics Training Package under development by the
University of Cairo in Egypt. The Egyptian PI will spend four weeks at
Elizabeth City State University to train the team. Packages generated
will be used by underclassman physics majors at the University of Cairo.

USING PHOTOREALISTIC RENDERMAN SOFTWARE TO RENDER IRIS EXPLORER
GEOMETRIC MODELS
C. Fields, Math and Computer Science Department, Elizbeth City State
University.
Advances in three-dimensional computer visualization has been a major
factor in the dvelopment and production of high quality images. The use
of three-dimensional viewing has become an essential issue in several
academic sectors and the commercial product development. Advanced
endeavors are worthless unless the results can be clearly communicated.
Some type of verbal and/or visual medium should be used to interpret the
data and to report the results to others. Computer Visualization gives
one the opportunity of using photorealistic Renderman software to
produce high quality images from IRIS Explorer geometric models and
generate movies from these images by using an application known as Movie
Maker. Visualization software is also used to generate these geometric
models which are derived from NASA's Earth Radiation Budget Experiment
or ERBE. The ERBE is a scanner instrument package which contains three
instruments that are used to measure shortware, longwave, and total
waveband radiation. It was decided to visualize the radiation data
monthly over a period of four years.
The software package IRIS Explorer is a visual programming system for
data visualization, maniplulation, and analysis. The software package
IRIS Explorer is a visual programming system for data visualization,
manipulation, and analysis. The system has a programming component which
developers use for creating new applications and a user environment in
which the application runs. IRIS Explorer runs all Silicon Graphics
workstations and is available for other UNIX-based workstation and
supercomputers.

THE STATISTICAL ANALYSIS OF CONSUMER'S COICE IN ATHELETIC FOOTWARE
Lakisha Mundon, Peter Ely, Charmaine Morgan, Tashia Tillet, Department
of Math and Computer Science, Elizabeth City State University
This research involved conducting a study to determine which factors
effect the way consumers purchase athletic footware. The most effective
way to conduct this research was to create a specifically designed
questionnaire. The data collected was analyzed statistically by using
the techniques for categorical data. Cross-tabulation and chi-square
procedures were used to determine the significant effects. The primary
factors which influenced the consumer decision-making process were the
type of shoe, the brand name, and the shoe price. Other variables that
may have played a role in the selection process were race, age, salary,
and sex. These were the independent variables. The dependant variable
was the consumer's preference for the athletic footwear.

APACHE VS. NCSA HTTPD
Kuchumbi Hayden, Pamela Clanton, Marcia Granby, Department of Math and
Computer Science, Elizabeth City State University
The purpose of this research project was to explain how to set up a
World Wide Web Server using two different methods. The server is based on
the HTTPd server developed by the National Center for Supercomputing
Applications(NCSA) verses Apache 1.2.5.
The National Center for Supercomputing Applications (NCSA was developed
at the University fo Illinois at Urbana-Champain in 1985 with a grant
from the National Science Foundation. NCSA is responsible for one of the
most popular servers in this day and agte. The NCSA server will compile
and run on most UNIX systems.
The Apache server is a freeware Web server written by the Apache Group,
a non-profit organization of volunteer software developers. Apache is
known to work with microcomputers and workstations running Solaris,
SunOS, NeXT, HPUX, FreeBSD, BSDI, Irix, Linux, SCO, AUX, AIX, DEC Unix,
Ultrix, and UnixWare variants.
This research involved studying all aspects of installing a server. This
included understanding which configuration files are need and how they
work.
The Unix workstation involved is named Sun17. Sun17 is a SPARC
workstation machine located in Lester Hall at Elziabeth City State
University(ECSU). The Apache web server is used as a backup for the ECSU
NCSA webserver.
This research compared three security issues:
1. Login names and passwords needed to download certain documents.
2. Using proxies.
3. Using virtual hosts.

VRML 2.0-VIRTUAL MODELING LANGUAGE VERSION 2.0 DEVELOPMENT AND
INTERACTIVITY
D. Charity. Department of Math and Computer Science, Elizabeth City
State University
The purpose of my internship here at Naval Research Lab was to develop
programs and script in VRML to make interactivity between the user and
program more efficient. Also, to develop template programs to cut back
length of scripted programming and time of production by inlining object
files into the multipurpose event handling script generated in the
template file.
The script developed will be used to inline multiple object files into
real time battle situations with full versatility in movement in a
Netscape browser. All template files have the option of moving an object
in the XYZ plane of the virtual world. This is important in the
development of real-time battle situations.
Another helpful tool is the capability of VRML and Javascript in creating
Javascript, opens the world of highlighing, movement, and also
mouse-over events. Used along with VRML, the programs developed become
more powerful and user friendly. Another advantage in using the template
files is that the programmer is able to switch in and out of objects he
or she wants to see in full movability. VRML is becoming a broader
research field at the Virtual Reality Lab because of its accessibility
and viewability through Netscape.

DIFFERNTIAL EQUATIONS FROM A DYNAMICAL SYSTEMS POINT OF VIEW
Ayonda Moore, Arthur Fenner, Brian Jordan, Micheal Pugh, (Dr. Dipendra
Seqngupta) Department of Mathematics and Computer Science, Elizabeth
City State University.
This research concerns the chaos involved in nonlinear dynamical
systems. To gain some understanding of nonlinear dynamical systems we
began our study with linear systems including homogeneous and
non-homogeneous LRC (inductor-resistance-capacitor) circuits. In the
latter case, we explored the phenomenon of resonance in a force system. We
then used Mathematica to develop a complete classification including
graphical representations of all possible dynamics to second order
linear systems. With this information, we were able to depict the
bifurcation diagram for these solutions. Then we moved on the LRC
circuits including a semiconductor to add an element of nonlinearity.
This closely modeled the Van der Pol equation. With the use of Jacobian
and other methods we linearlized these systems near the equalibrium
points to get a qualitative concept of the systems. The next nonlinear
system that we explored was the force pendulum which has chaotic
behavior in certain regions. We again used MATHEMATICA to understand the
periodic and chaotic behavior of the system and find Lyapunov exponent.
Our future research will involve methods of controlling the chaos by
steering it into periodic orbits and use the model to control the noise
of communitcation system. Thsi research is funded by NASA LEWIS CENTER.

ZERO-BASED RULEMAKING PROJECT
S. Joyner. Department of Math and Computer Science, Elizabeth City State
University.
The ten-week internship at the Department of Transportation involves
work with the Office of Moter Carriers. Currently, the Office of Motor
Carriers is working on a project called the "Zero-Based Rulemaking
Project". The "Zero-Based Rulemaking Project" was launched in 1992 to
improve the organization, format and clarification of the FMCRs. The
goal of this intership project was to establish a Web page for the
public in which there are links between the FMCRs and various other web
sites.
To complete this process, various software packages such as Frontpage
and Microsoft Network Composer were utilized. Knowledge of the overall
structure of the agency, and how various regulations become official was
also a prerequistie.
During this project, the need to learn a new technical vocabulary used
by the Office of Moter Carriers and the Plain English Movement was
essential.

REALTIME CLCS
K. Godwin. Deaprtment of Math and Computer Science, Elizabeth City State
University.
The Checkout and Launch Control System(CLCS) mission is to replace the
current Launch Procession Syste(LPS) with standard-based Commercial
Off-The-Shelf(COTS) system and custom software. It will utilize
multi-vender platforms tied together with standard Local Area
Network(LAN) technology. A program mandate is to replace the exisitng
LPS without causing changes to existing flight hardware or software and
with no impact to the flight manifest.
Ultimately, these tools will mature into a deliverable suite of tools to
be used by the Operations Engineers in their day-to-day activites, as
well as generating data to be used in the vendor selection of various
network components. The tools are generated in the "C" programming
languate within the Unix environment and untilzied, at a minimum, the
User Datagram Protocol(UDP) and the Internet Protocol(IP) via the use of
Unix sockets.
