                                                       with some of the resources to take their programs up another level.”

                                                       UF is also eligible to receive $768,750 in matching funds from

                                                       bringing the potential cumulative value of the gift to more than $2
                                                       million.

                                                       UF has been the number one university recruiting source for Harris
                                                       for the past five years. Harris currently employs 460 UF graduates
                                                       and recently recruited an additional 22 from the spring graduating
                                                       class.

                                                       “The Harris Corp. has certainly demonstrated that they are tuned in
                                                       to our initiative to build on our world-class faculty,” said Machen.
                                                       “The partnership represented by UF’s relationship with Harris is
                                                       exactly the type of public-private partnership that makes public
                                                       research universities successful.”

                                                       UF’s Faculty Challenge initiative was launched by Machen in
                                                       August 2004, with a goal of raising $150 million to give faculty
                                                       the tools they need to enhance classroom instruction and conduct
                                                       world-class research. The Faculty Challenge is part of a plan to
                                                       make UF one of the nation’s premier research universities.

                                                       In recognition of the gift, UF will name the rotunda, entry

estimated it would cost $1.3 trillion dollars to upgrade our national
infrastructure to acceptable levels. The Association of State and

                           can contribute to new technologies such as CO2 pt sequestration. The US

the feasibility of storing large quantities of CO2 in underground formations, thereby reducing the           BS        MS        PhD
atmospheric excess. At present, models of fracture dissolution are largely phenomenological, relying         76        8         18
on average flows and effective mass transfer coefficients. However, such approaches are unreliable
due to the strongly non-linear feedback between transport and kinetics. The work of Professor Tony           2004	Fall	Enrollment
Ladd and his research group is aimed at developing a microscopic and fundamental description of the          BS        MS        PhD
erosion process, which can then serve as a test bed for statistical theories that are necessary to connect   354       24        70
laboratory and geological scales.

Professor Ladd and his group have developed numerical simulations of fracture dissolution at the
laboratory scale, comparing erosion morphologies with experimental results for a specific initial
topography. The simulations include fluid flow in the specific fracture geometry, transport of reactants
and products, and chemical kinetics at the eroding surfaces. New algorithms have enabled them
to simulate systems of comparable scales to those studied in the laboratory, but with more detailed
information about the fluid flow and chemical transport.

                          developed portable weather stations to capture the true behavior of ground

                          instrumentation in the path of landfalling storms to collect wind velocity data,    BS        MS          PhD
                          as well as dynamic uplift pressure on the roofs of residential structures. The      600       93          92
                          wind data is transmitted in real-time during the storm to a public access Web
                          site (www.ce.ufl.edu/~fcmp). Atmospheric scientists at NOAA’s Hurricane
Research Division and the National Hurricane Center use the data to test their remote sensing
capabilities, and interact with the team to optimize deployment locations.

The consortium (UF, FIU, Clemson, FIT) captures this data to provide a direct measured link between
the turbulent ground level wind behavior, structural loading, observed damage, and cost effective
mitigation solutions. In 2004 the group’s efforts resulted in the only known source of directly measured
full-scale loading of an occupied structure during sustained hurricane force winds. The data captured
from the roofs of the instrumented homes will be compared with wind tunnel studies of those houses
and ultimately with American Society of Civil Engineers wind load provisions. During spring 2005
the team also conducted a quantitative study of the performance of the Florida Building Code (FBC)
for the Florida Building Commission. More than 200 randomly selected homes were inspected in the
highest wind zones of hurricanes Charley, Frances, Jeanne, and Ivan. The Florida Building Commission
is currently considering a range of code improvements based in part on the study findings.

landmine detection. Traditionally, human operators with metal detectors searched for landmines.                Business colleges.
However, most modern landmines are encased in plastic and very difficult to locate with metal
detectors. Therefore, sensors that can “look” underground, such as ground-penetrating radars, acoustic
devices, and hyper-spectral imaging spectrometers, are under investigation at laboratories around the
country. The CISE researchers are developing methods to automatically analyze the complex signals
produced by these sensors to discern the presence of landmines. The goal is a robotic system that can
detect and clear landmines automatically, thereby reducing the threat to human life.

The research team uses many tools including signal and image processing, statistical pattern recognition
and machine learning, artificial neural networks, and intelligent systems for decision-making. They
also apply knowledge of the physics of sensing processes (e.g. electro-magnetics, acoustics, imaging
spectroscopy, etc.).

The research is both theoretical and applied. Methods based on state-of-the-art theoretical techniques are
implemented on real systems and field tested. In the past four years, at least seven blind field tests have
proven the algorithms perform very well, sometimes reducing false alarm rates by orders of magnitude.

                         in the foam that insulates the Space Shuttle’s external tank. In February 2003,
                         the catastrophic failure of Space Shuttle Columbia was caused by a piece of        2004	Fall	Enrollment
                         foam striking the wing during liftoff. The Space Shuttle Discovery on its          BS       MS        PhD
                         takeoff in August 2005 was also struck by foam, leading NASA to postpone           1115     116       159
                         further flights until 2006.

Small voids are created during the deposition of foam insulation on the tank exterior. These voids
become pressurized due to cryogenic temperatures at the surface exposed to the tank and aerodynamic
heating on the surface exposed to air as the shuttle is accelerating to low-earth orbit. With enough
pressure, the cracks can propagate toward the surface of the foam and large pieces can fall off the tank
surface. The investigation focuses on the propensity of the foam to fracture off the tank surface by a
combination of experimental testing of fracture specimens and finite element modeling. Additionally,
the foam is not an isotropic material. Calculations for the stresses, displacement fields, as well as the
stress intensity factors must include the effects of anisotropy.
