Current Neural Network Model
Zorayr Manukyan
Client: Dr. Jonathan Bell,
Department of Mathematics and Statistics,
UMBC
In this talk we will introduce the model (integro - differential equation)
describing electrical activity of neural net, will discuss the numerical
method for solving it and how relationship between parameters in the model
results in different type of wave phenomena.

Cluster Analysis for Compositional Data
Ronny O. Vallejos
Client: Dr. Erle Ellis,
Department of Geography and Environmental Systems,
UMBC
Cluster analysis is a statistical technique of interest
in many different fields for grouping data. This work presents a clustering
technique to deal with compositional data. That is, data
consisting of vectors in which the components are proportions
adding up to one. Various strategies for replacing zeros in the
data are discussed. To illustrate the method we present the
analysis of a data set from the Yangtze Plain region in China.

Data Analysis for Concentration of Atrazine in Ground Water and
Area of Influence
Justin Newcomer and Rupa Bhensdadia
Client: Mr. Earl Greene,
U.S. Geological Survey,
Baltimore, MD
Atrazine (a pesticide) is used to control broadleaf and grassy weeds.
The U.S. Environmental Protection Agency has set some standards for
maximum contaminant level of Atrazine in drinking water.
It is assumed that the Response variable, concentration of Atrazine can
be predicted with logistic regression. The model was fit using various
explanatory variables, collected for sample units. Also, an analysis
was done to find the area of influence for the above stated study.

Sensitivity Analysis on the Plague Model
Stephen Clark and Jonathan Desi
Client: Dr. Holly Gaff,
Dynamics Technology, Inc.,
Arlington, VA
Plague is considered a prominet disease threat. In the past,
outbreaks have affected large amounts of the population. Today,
the threat of plague being used as a biological warfare and a
terrorism agent is a realistic possibily. Researchers have
studied this topic and developed a mathematical model of
differential equations to understand how plague behaves. Our
presentation will look at some sensitivity analysis on certain
parameters in the model to see how the behavior is affected.
This analysis will hopefully help researchers in this area better
understand the behavior of plague.
