Current and Past Projects
- 2005-2008 National Institute of Justice. In Progress
The Applied Mathematics Laboratory is working with the National Institute of Justice to
determine the optimal police search area for a serial criminal.
- 2004-2005 Carroll Area Transit Systems. Analysis of the Carroll Area Transit System
The Applied Mathematics Laboratory worked with Carroll Area Transit Systems to provide
statistical models that can be used to predict the optimal number of vehicles needed for the system.
The team also analyzed the current operations of the system, and compared different bus scheduling
algorithms.
- 2003-2005 Baltimore County Department of Environmental Protection and Resource Management.
Rural Baltimore County Domestic Well Analysis
Two AML teams analysed the data provided by the county to look for patterns in the failure
rates of rural domestic water wells.
- K. Koepnick and X. Wang,
Logistic Regression Analysis of Well Failures in Baltimore County
(Under consideration)
- 2002-2003 Baltimore City Fire Department. An Analysis of the Optimal Staffing Level of the Baltimore City Fire Department
This project determined an approximately optimal staffing level for the Baltimore City Fire Department

- 1998-99 Science Applications International Corporation (SAIC).
Validation and Enhancement of Applications of Models from Epidemiology to
INFOSEC Assurance Metrics
This project investigated the use of epidemiological models to simulate
and analyze the spread of computer viruses through a corporate
network.
- 1996-97 Bell Atlantic Network Engineering and Capacity Management.
Customer Usage Profile for Fast-Packet Frame Relay
The AML team developed customer usage profiles for the relay of fast
packets through the communications network. Data communications engineering
and queueing theory were used to develop models for projection of network
impact, processor occupancy, and link utilization in the network serving
Bell Atlantic's industrial and business clients.
- 1995-96 Towson State University, Academic Services
A Computer-Adaptive Mathematics Placement Test
The AML adapted a computer-based mathematics placement test from the
nationally recognized series of tests available from the Mathematical
Association of America. The AML test is computer-adaptive and uses
information about the student's background to customize the level of the
test and adjusts as the student takes the examination. Students are advised
on placement in accordance with their skill level and their major.
- 1993-94 Martin Marietta Aero and Naval Systems
Interface Between Database System M/Vision and Statistical Software Stat17
The AML team wrote a front and back end to a statistical package linked
at the laboratory bench to a materials database used in the production of
state-of-the-art marine and air craft.
- 1990-92 Becton Dickinson Microbiology Systems
Scheduling Production of Prepared Plated Media
Plates treated with growth media used for cultivation of bacteria used in
disease diagnosis are produced on several production lines at the Becton
Dickinson Hunt Valley installation. The scheduling package designed by the
AML optimizes the weekly schedule and takes account of inventory,
quarantines, cleanup and setup times on three of the busiest lines.
- 1989-90 Towson State University, Academic Services
An Enrollment Model for Resource Scheduling
An AML team developed software to help the Registrar's office schedule
courses based on the changing demands within majors and in the requirements
for degrees.
- 1988-89 BlueCross BlueShield of Maryland
Statistical Survey of Long-Term Care Patients in Nursing Homes
Towson actuarial science students and other mathematics majors
investigated the length-of-stay of Marylanders in nursing homes for the
purposes of helping the sponsor to evaluate the marketing and pricing
strategy for long-term care insurance policies.
- 1986-87 State of Maryland, Comptrollers Office, Retail Sales Tax Division
Estimation of Sales Tax Liability
Calculation of the liability of sales tax to be paid to the State of
Maryland by retail companies doing business in the state had been obtained
by teams of auditors combing through all of the business' records. The AML
team wrote software to allow for just one or two auditors to select a
stratified sample to estimate the tax liability with a high degree of
accuracy.
- 1985-86 Citicorp of Maryland
Customer Service Queuing Model
The Citicorp Choice credit card service desk had varying needs for
operators and telephone lines. By setting up a real-time scheduling device,
the AML team helped Citicorp meet its service goals on the help-line.
- 1984 A. A. I. Corporation
Acoustical Pattern Recognition
Students in physics and mathematics joined together to study the
acoustical signatures of several vehicles in an attempt to design a remote
recognition device.
- 1983-84 Union Trust Company of Maryland, Operations Center
The Collection of Cancelled Checks for Processing
Union Trust had 85 branch offices in all parts of Maryland. The AML team
developed an algorithm for the collection of cancelled checks from the
branch offices for processing at the central Guilford Avenue center. The
system was written to take into account the volume of check activity at
branch offices, the monetary value of the checks, and the efficiency of
routes.
- 1982-83 Westinghouse Electrical Corporation, Electronics Repair Center
Optimal Test Station Loading
The Electronics Repair Center services parts for airplanes used by the
Armed Forces. The AML team developed a scheduling program to help the
service center minimize the time that a part is in the center for
evaluation, repair and inspection.
- 1980-81 Towson State University, Auxiliary Services
Student Housing at Towson State University
The student-faculty team investigated demographic and enrollment trends
and projected the on-campus residential needs for Towson State. The
projections were used in presenting the funding package to the legislature.
