    Why We Do Student Design Projects?

    At Florida Institute of Technology, all chemical engineering, civil engineering, computer science,
    electrical and computer engineering, marine and environmental systems, and mechanical and aerospace
    engineering students are required to complete a senior project.

    Student Design is intended to enhance the student’s repertoire of professional problem-solving and
    engineering design skills in the context of realistic engineering situations.

    The Senior Design experience is the culmination of four years of engineering learning. The students
    work in teams to formulate the problem, propose an engineering solution or a design in the presence of
    technical and socioeconomic constraints, and make sound professional judgments among alternative
    solutions.

    The experience is not just for the senior year. Underclassman gain project experience from the student
    organization projects, like the ASCE concrete canoe or the Rocket Club. They also are invited to work on
    the senior project teams.

    Engineering is much more than taking theory and applying it to the real world. It’s about translating
    those efforts into solutions to the grand challenges facing the world. Students learn to solve issues such
    as project management, organizational learning and development, team communication, budget and
    financial matters, and safety by doing.

Why We Do Student Design Projects?

Most engineering students are individualists. Sharing data and ideas is often thought of as cheating.
Senior Design projects round out the student and prepare them for working in industry. Senior Designs
give students the opportunity to:
•   Participate in team goal-setting
•   Develop a plan to attain goals
•   Develop leadership by leading their own teams
•   Understand team interdependencies
•   Develop a winning attitude
•   Develop an awareness of customer needs and communication

Engineers turn ideas into reality. There is no better way to teach that than hands-on design. Student
projects makes engineering education “FUN.” If you want hands-on experience and the chance to do what
others only think about, you will find it at Florida Tech.




Engineering teaches you how to think. It is a systematic approach to problems and how to
structure solutions that helps in other areas.

Chemical Engineering



    Chemical Engineering.
    Chemical engineers turn ideas discovered in laboratories into practical devices and processes that can be
    manufactured on a large scale.
    Chemical engineers apply a combination of biology, biochemistry and/or chemistry with math to
    solve problems in a variety of areas using the equipment needed to bring these ideas to life. Chemical
    engineers have helped do this by performing research and development or by design and operation of
    processes that:
        •   Manufacture pharmaceuticals, making them cheaper and safe for people to use
        •   Work with medical doctors and biomedical engineers in projects such as the design and development of
            artificial organs and other medical devices
        •   Refine oil into petrol, keeping petrol prices low and improving petrol quality so it doesn’t pollute the air
        •   Generate electricity in the most efficient fashion to preserve our natural resources and protect the
            environment
        •   Create renewable fuels and energy sources to replace coal, petrol and gas (such as the hydrogen fuel cell)
        •   Produce safe drinking water from rivers, groundwater or the sea for city, rural and remote aboriginal
            communities
        •   Help the chemical industry comply with EPA regulations for the protection of the environment, like safely
            treating toxic hazardous industrial wastes so their disposal does not harm the environment
        •   Create composite materials, such as ceramic tiles protecting space shuttles at re-entry
        •   Develop artificial intelligence systems to control processes such as the operation of chemical plants or the
            space shuttle launch
        •   Carry out processes such as plasma etching of silicon wafers used in the manufacturing of computer
            microchips
        •   Help the wine industry make premium wines for export more consistently and at lower cost
        •   Improve mining techniques so they minimize environmental damage and cost less

    Chemical engineers have the opportunity to enjoy a diverse career, and there are a range of different
    jobs from which to choose. You can work in a laboratory, in an office, in the outdoors or on an industrial
    plant, or combination of all of these in the one job. Some industries and careers that chemical engineers
    are involved in include:
        •   Biotechnology and pharmaceutical industries
        •   Winemaking
        •   Food production (e.g. beer, milk, cheese)
        •   Petrochemicals (e.g. gold, rare earths, oil refining, natural gas, plastics)
        •   Industrial chemicals (e.g. detergents and soaps, chlorine, explosives)
        •   Mining and minerals processing (e.g. iron ore, steel manufacture, aluminum)

    Industrial Feasibility of a Low Capacity Crude Petroleum Refinery (LCCPR)
    Project Team: Khalid Al-Mehairi, Joseph M. Daniel, Alejandro Osorio

    Project Description:
    Though a great deal is known about crude oil petroleum refining, this project seeks to discover the
    economic feasibility of using a low capacity crude petroleum refinery (LCCPR). Recent calculations
    indicate that, in this ever-changing economic and political climate, it has now become more profitable
    to build small petroleum plants that just refine crude oil into gasoline, diesel fuel and jet fuel and sell the
    rest of the crude off to the large refiners to produce the rest of the spectra of petroleum products.

Hydrogen Production Using an Algal Reactor

Project Team: Ahmed Al-Hammadi, Connor Cook, Lisa Stapleton

Project Description:
The purpose of this design is to explore hydrogen production processes that use micro algae: HISTAR and
Bioreactor. The goal is to develop a cost-competitive system for algal hydrogen photo production that is:
    1.)   Renewable (uses H2O as the substrate and light as the source of energy)
    2.)   Stable and self-containing
    3.)   Efficient
    4.)   Clean


Equipment for the HISTAR algal reactor includes:
   1.) A tank for nutrient/water mixture
   2.) Turbidostats to continuously culture the algae
   3.) CFSTRs to increase the amount of biomass produced
   4.) Either a PSA unit or cell membrane to purify the H2
   5.) Controllers needed are transducers, transmitters and valves for flow, pressure and temperature as well as
       separate monitors for the turbidostats and CFSTRs.


Equipment for the algal bioreactor includes:
   1.) Algae production bioreactor for production of algal biomass
   2.) Algal settling tank
   3.) A fermentation tank for dark production of H2 (~1/3)
   4.) Photo bioreactor for completion of H2 production
   5.) Either a PSA unit or cell membrane to purify the H2


The H2 production rate is estimated to be 10ml/hr/mg dry wt for an algal mass density of 1g/l for a
photo bioreactor of dimensions 20m x 4cm having two sets of eight tubes. The estimated liquid volume
per tube is 230L. Controllers needed are transducers, transmitters and valves for flow, pressure and
temperature as well as a pH monitor to control CO2 flow.
The cost for each method of hydrogen production from algae has not yet been calculated to determine
if either is a competitive source of hydrogen production.

  Purification of Hydrogen Gas from Refinery Off-Gases

  Project Team: Nathan Miller, Tanyka Sham Ku, Yunus Mwinyimvua

  Project Description:
  For near-future expected hydrogen fuel cell applications, an impurity concentration less than 10
  ppm (parts per million) is desired to prevent catalyst deactivation. The proposed design uses steam
  reformation of methane to produce hydrogen, then purifies the hydrogen stream via pressure swing
  adsorption. The desired purity is then achieved by further purifying the impure H2 stream using a
  palladium membrane. The target purity of the hydrogen stream is 99.9999% or “Six Nines” purity.

    railways, highways, dams, pipelines and major buildings that assist our way of life. Civil engineers are
    usually found in one of the following groups:

        •   Construction Engineer—Construction engineers design and repair the framework for all types of buildings,
            towers and amusement park rides. They may also be involved with projects such as developing innovative new
            offshore oil rigs in locations that were previously considered unstable.
        •   Environmental Engineer—Environmental engineers are concerned with local and worldwide environmental
            issues like the effects of acid rain, global warming, ozone depletion and wildlife preservation.
        •   Geotechnical Engineer—Geotechnical engineers try to solve problems involving the ground and groundwater
            and design structures in and below ground.
        •   Structural Engineer—Structural engineers are concerned with designing a structure that encloses or spans over a
            certain area.
        •   Transportation Engineer—Design and repair roadways, railways and bridges.
        •   Water Resource Engineer—Water resource engineers are concerned with the structural and nonstructural
            solutions to water control, utilization and management.

Your Kidding, a Concrete Canoe Competition?

By Paul J. Cosentino, Ph.D., P.E.
Professor Department of Civil Engineering,
Florida Institute of Technology

Whenever the topic of a Concrete Canoe is mentioned, people sure get a funny look on their faces. I
have been involved with this student competition for nearly two decades, and I promise it is for real.
You ask how can concrete float? Well many materials heavier than water float when properly designed
to displace their weight. There are steel ships everywhere; in fact during World War II, concrete boats
were built for battle. So the basic idea of making concrete into the shape of a canoe is not really unheard
of. However, these canoes float full of water or when swamped, so that they would not sink during the
highly competitive series of races.

This competition was developed to allow college engineering students to work with one of the most
common construction materials in the world while having fun. Each year they are asked to construct a
canoe that meets very stringent specifications developed by a committee of experts from the American
Society of Civil Engineers (ASCE). They must write a report describing the design, construction and costs
associated with the project, then they are asked to do a 5-minute presentation about the work. After
these two tasks are completed the group must display their product to the judges, swamp it to prove
it floats and compete in a series of five races. The races are exciting with the students gaining paddling
experience from various sources. Here at the Florida Institute of Technology, we were very fortunate to
meet a world-renowned paddler by the name of Dennis Beek. Mr. Beek has been heavily involved in flat-
water racing for more than 20 years. He was invited to the United States Olympic Qualifying races in the
1980s and helps competitive canoe and kayak paddlers worldwide.

With Beek’s help, the passion of our engineering students and support from our alumni and friends we
have produced five teams that have qualified for the National Concrete Canoe Competitions, including
one National Champion (1997) along with third, fourth and sixth place finishers in 2000, 1998 and 1999.
Each year our students work countless hours perfecting the canoe. The finishes of the most competitive
hulls looks like a tabletop and our last two canoes had a polished glass finish in a blue and aqua concrete.

In addition to the national recognition, one of our personal highlights was a congratulatory letter from
the CEO of the Olin Foundation, Mr. Larry Milas. As this foundation was preparing to present our school
with their largest gift ever, $50,000,000, Mr. Milas sent a letter that stated, “Their kind of success was the
reason we chose to support Florida Tech with our $50 million commitment. Being a “giant killer” like
Florida Tech is, breeds competition and is healthy for higher education.”

    Steel Bridge Competition

    Project Team: Richard Pruss

    Project Description:
    The American Institute of Steel Construction (AISC) and the American Society of Civil Engineers (ASCE)
    sponsor the AISC/ASCE National Steel Bridge competition. Civil engineering students from more
    than 200 universities compete at a regional level, and the top two or three teams are then invited to
    participate at the national competition.

    The purpose of the competition is to design, fabricate and assemble a 1:10 scale model of a bridge to
    meet certain specifications set forth in the rules. Each year the rules are modified so that a new bridge
    design is necessary to complete the design task. Students are challenged both mentally and physically.
    The students must develop a structurally efficient design based on weight, ease of construction, strength
    and aesthetics. Also, the students must physically be able to assemble the bridge as quickly as possible.
    Through the entire process of design, fabrication and assembly, students learn to use the engineering
    knowledge they gained in the classroom for a practical purpose, which adds to their educational
    experience. The assembled bridges are tested under both vertical and horizontal loading conditions.
    Points are awarded for speed of construction, aesthetics and performance under the various loadings.

Free Space Optical Link
Project Team: Vivek George, Nirmit Gang, Abdullah Algamdi, Matieb Alenize

Project Description:
The purpose of this project is to create a wire-free link between two computers and transfer data back
and forth. For this we are using two lasers, each connected to one computer, for the optical transmission
signal. Free space optical (FSO) doesn’t need any license, can be deployed vary quickly and easily, and is
much cheaper than laying a new fiber over short distances. In order for the digital signal to be transmitted
and received, there must be clear line of site between each wireless optics unit. In other words, there
should be no obstructions such as trees or buildings between the transceiver units.

Expected Outcome:
Upon the completion of this project, we would like to establish a LAN-to-LAN connection between the
two computers. Also, transfer large data files over the established network and reach speeds up to 1.5
Mpbs.

FOPS Emergency Occupancy Counter

Project Team: Mike Succio, Lori Shields, Chien Nan Ou, Jeffrey Laub, Nikolay
Grigorov, Devin Hopkins, Gayrajan Kohli

Project Description:
The purpose of the Emergency Occupancy Counter is to be able to detect when a person has entered
or left a building. This will be useful in case of an emergency, knowing exactly how many people are in a
building at a given time. Our goal is to make this system accurate and sensitive enough to detect people
of all weights, including small children.
The system will consist of a power supply that will feed the source circuits, the detector circuits, the
microcontroller and the LCD display. There will be two sets of source and detector circuits in all. The light
source will travel through the optical fiber to the mat. Inside the mat, there will be a microbend sensor
that will deform the fiber when pressure is applied to the mat. When the fiber is deformed, there will be
less light reaching the detector circuit. The detector circuit will then feed a signal to the microcontroller.
The software in the microcontroller will be able to tell what direction a person is going by which mat
is pressed first therefore keeping track of how many people have entered or exited the building. This
number will then be displayed on a Hitachi LCD display.
First we are going to check to see if one of the mats was pressed. Once we find which mat was pressed,
we then check to see if the other mat was pressed. If so, the microcontroller will either decrement or
increment the counter. This is when the software will send the number in the counter to be displayed
on the LCD. If the second mat was never pressed, then the software will go back to the beginning of the
program.
Having such a system will aid is search and rescue efforts. By placing this system in every doorway in a
building as well as elevators, stairwells and other emergency exits, a count can be obtained as to how
many people are
in what rooms
in the building.
This all can be
monitored in a
central location
and can be sent
to emergency
personnel when
an emergency
occurs.

Crack’d Case

Project Team: Bryan Stoddart

Project Description:
The Crack’d Case team’s project is developing a software
system to assist law enforcement investigators with their
casework. This software package has two main parts
analysis and case management.
The analysis portion of this product will allow investigators to do some of their own analysis. This could
help decrease the time needed to solve a case, since the investigators will not need to wait for an analyst
for many of the most commonly used reports; it will also free up analysts for other tasks.
The case management portion allows investigators to monitor the progress of their cases by tracking
numerous aspects of the case. These aspects include the status of assigned tasks, budgeting and
expenses, witness availability, evidence movement tracking and other things.

ROSS—Remotely Operated Surf-Zone Surveyor
Project Team: Adam Outlaw, Jenna Vogt, Walker Dawson

Project Description:
The Remotely Operated Surf-Zone Surveyor (ROSS) will revolutionize the way beach profiles are
performed. The conventional method of using stadia rods and surveying equipment to perform beach
profiles is very time consuming and inaccurate. ROSS will not only allow for multiple profiles in one day,
it will also produce surface elevation data instead of the conventional two-dimensional cross section.
The vessel consists of the Laipac UV40 DGPS receiver, a Motorguide 44lb thrust trolling motor and a Hitec
Laser 4 RC transmitter and receiver. There are limitations however, involving ROSS.
Constraints of ROSS mainly involve limitations of the vessel’s stability and the instrumentation. The size
and stability of the vessel limit the size of the waves in which ROSS can be deployed. The accuracy of the
sonar can also be compromised by the amount of air bubbles present in the water.
Although the initial project scope was not completed, the vessel is now remotely operated with GPS
positioning capabilities. Testing of both the maneuverability of the vessel and the DGPS unit were
completed. The functionality of these two components was confirmed.
ROSS is now ready to be equipped with more instrumentation to fulfill its initial purpose. Some needed
modification would allow ROSS to meet the needs of the original project scope. Modifications to the hull,
the sonar and the configuration of the instrumentation would make ROSS a much more efficient piece of
research equipment.




                                                                                2005–2006 Senior Design Projects 43

PHISH—Perfected High-Speed Internal-Combustion Solar Hybrid

Project Team: Adam Lucey, Mark Stroik, Zak Chester, Enrique Acuna

Project Description:
Team PHISH, an acronym for Perfected
High-Speed Internal-Combustion Solar
Hybrid, was created to determine if a
hybrid propulsion system was feasible
in the marine industry. The proposed
task was to create a boat that has
multiple power sources. PHISH utilizes
a combination of electric-solar and
gasoline engines. This combination was
chosen due to its simplicity, following
a similar trend in the automotive
industry. Several other hybrid systems
are also available such as hydrogen-
electric propulsion.
The completed project was successful and the objectives were achieved. The boat reached a top speed
of 5 knots. All systems worked properly; however, the top sprocket was misaligned and caused the chain
to vibrate off at high speed.
Future recommendations and changes should include the trial of a serpentine belt system and tensioner,
which should eliminate the vibration. Further testing should be done to determine if it is feasible to draw
a current from the electric motor to charge the battery instead of the solar panel, since when the gas
motor is engaged, the electric motor is still spinning. It may be possible to use the electric motor as a
generator as well.




                                                                                2005–2006 Senior Design Projects 45

Hy-Prop Jet Boat
Project Team: Michael Card, Chris Cawood, Steve Martyr, John Whitehead

Project Description:
The Hy-Prop boat is a dual fuel source, hybrid electric, water jet propelled watercraft. It is designed to
investigate the future feasibility of alternate fuel integration and hybrid technology on a water-based
platform. The team, using an existing 1/8th scale hull, designed and outfitted it with all the necessary
components to create a self-contained watercraft. Through testing and observation, the craft exceeded
previously set expectations and proved its commercial viability as a hybrid vehicle if scaled to a full-size
application. Currently, the boat is calibrated to run on propane and will accept hydrogen as a fuel source.
The most frequent engineering hurdle involved with making a hydrogen-powered craft revolves around
the storage of the hydrogen itself. The problem of hydrogen storage could be solved in two ways.
One was to use a metal hydride storage unit, such as the PAssively-Cooled Electrically heated (PACE)
unit. This uses lithium hydride powder and heat to store the hydrogen gas at up to 200 times volume.
This hydrogen could be extracted by careful heating of the unit, allowing for variable production at
low pressures. Two of these units were designed and built by us using the department of chemical
engineering materials. All parts for the PACE units were constructed from stainless steel. The individual
pieces were brazed together using a silver solder compound. This provided structurally stable joining
for the parts and ensured that the hydrogen did not leak out of the welds and that the individual
components would not melt.

Autonomous Mobile Buoy
Project Team: Zachary Pfeiffer, Michelle Rees, Safia Tappan, Derek Tepley

Project Description:
The goal of this proposal is the development and testing of an autonomous mobile buoy (AMB)
prototype to monitor coastal and lagoon areas, and collect data on ecosystems, processes and changes.
The end product of the project will be a fully automated, autonomous cost efficient modular system
on which various water-based measurement instruments can be mounted, for example: turbidity,
temperature, salinity, dissolved oxygen, radioactivity, hydrocarbons, chlorophyll, algae and phytoplankton
sensors, in addition to an array of meteorological instruments.
The project objectives include the development of an automated buoy with advanced control
algorithms that will allow the vehicle to perform autonomous pre-programmed surveys and sampling.
The AMB will provide a platform for continued research at Florida Tech’s Underwater Technology
Laboratory where autonomous devices are being developed that can reside and navigate in estuaries
and oceans, explore, collect data and search for specific biological, chemical or physical attributes
observed in the ocean environment.
Possible uses of the system encompass a wide variety of underwater and surface monitoring. These
include, but are in no way limited to, biological and chemical surveys, harmful algal blooms (HAB),
environmental assessments, wastewater management, documenting the distribution of harmful
invading species, weather hazards or long-term investigations in geomorphology, flora and fauna.

    FSAE Formula Car/Mechanical
    Project Description:
    The Formula SAE design project requires student
    teams to conceive, design, fabricate and compete
    with small formula-style racing cars. A very stringent
    set of rules is given for the design and competition
    in order to challenge the knowledge, creativity,
    imagination and skills of the participants. Each team
    has one year to complete the project, after which the car is taken to the Annual Competition for judging
    and competition against cars from about 140 other national and international schools. The goal of such
    design projects is to provide young engineers with working experience to successfully undertake future
    engineering design projects.
    As stated in the Formula SAE rulebook, the car must have “very high performance in terms of its
    acceleration, braking and handling qualities.” The car is to be a prototype for a vehicle that would be sold
    to nonprofessional weekend autocross racers and must be easy to maintain, reliable and be relatively low
    in cost (under $25,000). Each car is compared and judged to determine the best overall vehicle.

Project Description:
This project is an integration project in which a fuel management kit (MegaSquirt) is assembled and
mounted onto a motorcycle engine. This project is being built to provide the necessary engine control
for the FSAE Formula Car. The fuel management system is made up of two main components. The first
component of the project is the fuel injection system, where data is taken from sensors in the engine
compartment and used to calculate the required amount of fuel to send to the cylinders. The second
component is the ignitions section, which uses information about the rpm and load of the engine to fire
the engine sparks appropriately.

    SAE Mini Baja

    Project Team: Mike Wisnom, Addam Hogan, Jillian Maynard, Erika Howard,
    Aaron Durfee, Olusatosin Kolade, Chris Deighan


    Project Description:
    Mini Baja is comprised of three regional competitions that expose students to real-world engineering
    design processes. The students are to design and build an off-road vehicle that can withstand rugged
    outdoor terrain. The object of the competition is to provide SAE student members with a challenging
    project that involves the planning and manufacturing tasks found when introducing a new product to
    the consumer industrial market. Teams compete against one another to have their design accepted for
    manufacture by a fictitious firm. Students must function as a team to design, build, test, promote and
    race a vehicle within the limits of the rules, but also to generate financial support for their project and
    manage their educational priorities.
    Our main goal for the competition is to create the top performing Mini Baja at the competition. We plan
    to achieve this by creating a simple yet unique design that is competitive on an all-terrain environment.
    Secondly, we hope to gain a better understanding of the engineering design process and increase skill
    sets specifically in the field of mechanical engineering. Also, it is our goal to represent our sponsors in a
    professional and respectable manner.
    The cars are judged on a series of static and dynamic categories including: safety inspection, cost
    presentation, design presentation, speed/acceleration, power, suspension/maneuverability, and most
    importantly durability.

    Nick

    Project Description:
    Team Modju-Bot currently includes dedicated ME (Mechanical Engineering) and ECE (Electrical
    and Computer Engineering) students. Many of these students already have experience with robots
    having competed in the FIRST Robotics competition in high school and also constructing a robot as a
    freshman class project. This team has a very diverse background, comprised of students from all over
    the country as well as international students. The goal of this team is to create a robot that is versatile
    and easily adaptable. Everyone on the team is involved in all aspects of the process, from design and
    fabrication to fund-raising and documentation. This real-world experience will give these students the
    chance to be prepared when they are faced with design challenges in the future.
    The design objective for Modju-Bot is to create a robot that can accomplish various tasks through
    specialized components. These components will be designed as interchangeable modules. This design
    would allow the robot to be easily customized if a certain industry or person were to purchase it for a
    specified use, or set of specified uses. The main body of the robot is meant to be versatile enough so
    that only the attachments would have to be changed to accomplish different tasks.
    To meet the team’s design objectives, the design will need to include the following:
        •   Modular Design                                   •   Position Feedback
        •   Climb Stairs                                     •   Rotation Detection

    Project Description:
    The AURORA Team will design and build the first completely successful UAV at Florida Tech. The primary
    objective of the team is to design, build, and fly a completely autonomous aircraft in the 4th annual
    AUVSI Student UAV competition held in St. Inigoes, Maryland. Florida Tech will compete against other
    undergraduate student teams from other universities around the country. The aircraft must navigate
    a predetermined course, search and recognize targets, and return to “base” where the images of the
    targets can be processed autonomously. The team has designed and built the airframe of the aircraft
    completely on its own instead of using an off-the-shelf airframe. In addition, the plane must be capable
    of flying autonomously from takeoff to landing. In order to create an effective design for the aircraft and
    its systems, the AURORA Team is divided into 5 sub-teams: Structures, Propulsion, Aerodynamics, Stability
    and Control, and Electronics. The mechanical and aerospace teams are:

        •   The Structures Team is responsible for designing the airframe of the aircraft based on the aerodynamic
            design of the plane. They are also responsible for all mounting points for the subsystems of the plane.

        •   The Propulsion Team is responsible for designing the plane’s power plant. We have decided to use a nitro-
            fueled engine with a ducted fan unit to power the plane. The size of the engine and ducted fan required,
            the amount of fuel, and the fuel system are currently under design research and development.

        •   The Aerodynamics Team will design the aerodynamic surfaces of the aircraft. The wing, fuselage, and tail
            sections are all in the design process so that computer analysis and construction can begin.

    Team Members: Mark Campbell, Chris Cease, Robyn Evans, Rakesh Gupta,
    David Kincaid, Tim Pelletier, Saranya Raghavan, Lori Schwartz (Team Leader)




    Project Description:
    AURORA, Aerial Unmanned Reconnaissance Operations and Research Aircraft, is a Senior Design Project
    at the Florida Institute of Technology, College of Engineering, in Melbourne, Florida. The AURORA Team’s
    members represent a multi-disciplinary group of dedicated students ready to utilize the lessons taught
    in the classroom to design an unmanned aerial vehicle. The team will apply theory, think creatively, and
    develop practical skills such as teamwork, professionalism, and leadership as part of the Senior Design
    Program experience. The overall goal of the AURORA Team is to compete in the Seafarer’s Competition
    held in St. Inigoes, Maryland.

    The current drive in the field of reconnaissance has been toward unmanned, remote controlled aircraft
    with great functionality and that can provide effective reconnaissance for military applications without
    risking the lives of our nation’s pilots. Operators are able to pilot the aircraft remotely from thousands
    of miles away. However, a more effective method involves autonomous aircraft, that is, aircraft that can
    navigate a predetermined course, recognize their surroundings, and perform a specific task without
    any input from an operator. These autonomous vehicles improve the safety and lessen the cost of such
    reconnaissance operations.

        •   The Electronics Team (ECE) is responsible for developing the electronic systems to control the plane and to
            perform the aircraft’s mission. The payload will consist of an autonomous control unit, imaging and data
            storage equipment; ground-to-air communications equipment will be kept at a minimum. Ideally, air-to-
            ground communications and data transmission will also be possible. The completion of the Electronics
            Team’s tasks is paramount to the success of this project.

    Shock Tube

    Project Team: Joe Atkinson, Kyle Craig, Damian Harasiuk, Lasida Klinsuko,
    Crisen McKenzie

    Project Description:
    A shock tube is essentially a steel tube separated into four basic components, each performing a
    different function in order to generate a high pressure, high temperature flow. These components are:
        •   A driver section, which is filled with a high pressure gas mixture (He & Ar)
        •   A driven section, which is filled with the test gas (usually air)
        •   A diaphragm section, which is used to trigger the test
        •   A test section, which is used to gather data
    A shock tube works by pressurizing the driver section with a mixture of helium and argon, and
    evacuating the driven section of air to about 0.1 atmospheres. These specific gasses are used so that the
    testing time (usually 3 to 30 milliseconds) can be maximized. Diaphragms, which have been designed
    to burst at a specific pressure, maintain the pressure in each section until the desired driver pressure is
    reached.
    Once the driver reaches the desired pressure, the diaphragms burst and a shock wave is created. This
    shock wave travels down the tube heating up and pressurizing the remaining air in the driven section
    to very high pressures and temperatures. When the shock wave reaches the end of the driven section, it
    reflects off a secondary diaphragm and travels back through the driven section, further heating up and
    pressurizing the air. This high enthalpy (high temperature, high pressure) air is what is used for testing.
    The test gas behind the reflected shock wave then bursts a secondary diaphragm and enters a test
    section.
    A supersonic/hypersonic test section works by passing this high enthalpy air through several processes
    in order to generate the desired testing conditions. The first process that the air goes through is a process
    of laminarization (flow straightening). This means that the air flows through a device called a flow
    straightener, which takes out any turbulence in the airflow. This laminar air then goes through a process
    of acceleration to supersonic speed.
    The air flows through a device called a CD nozzle. This device squashes the flow and forces it to speed up
    to the speed of sound. The flow is then further accelerated by allowing it to expand against the walls of
    the device. The amount of expansion that the flow is allowed to undergo determines the Mach number
    (ratio of the air’s speed to the speed of sound) that the air reaches. This air is then sent through an area of
    constant cross section, where testing can take place.

    Spin Stabilized Surveyor
    Project Team: Mishaal Ashemimry, Jacquelyne Frederick, Ruth Galaviz

    Project Description:
    S3 is experimenting with spin stability using model
    rockets. The team will be using a model Aerotech
    Cheetah rocket to study spin stability in two ways:
    using a vane skirt attached to the end-closure of the
    motor and a spinning launch pad. A Cheetah rocket
    has already been purchased and received by the team
    and a vane skirt has been attached to the motor. The
    spinning launch pad is still under construction and looks
    promising.

     In order to measure the spin, a photocell will be
    mounted on the rocket and connected to a digital power
    recorder (DPR) that will measure the volts every time
    the photocell is hit by the sun’s rays. The solar cell will be
    recording some voltage due to the heat; however, when exposed to direct sun light, the voltage will be at
    a peak. It is these peaks on the graphs that will be analyzed from the receiver to determine a complete
    revolution. In order to test the vane skirt on the motor, the photocell receiver must first be designed. S3 is
    still in the process of creating a prototype for the photocell receiver.

    MATCH—Model Aircraft Turbojet Combusting Hydrogen
    Team Leaders: Adam Kearney, Kelly Currin
    Team Members: John Abraham, Angel Andujar, Joey Booker, John Farley, Melanie
    Hochmuth,
    Daniel Hoekstra, Daniel Hoogkirk,
    Brenton Kollinger, Erika Miranti, Joseph Pilon, Robert Runia, Toshi Umeta

    Project Description:
    Due to the need for environmentally friendly and efficient
    transportation, the MATCH (Model Aircraft Turbojet
    Combusting Hydrogen) senior design team at Florida Institute
    of Technology is creating the first hydrogen powered model
    jet aircraft. This project will be instrumental in terminating a dependence on fossil fuels, not only in the
    aerospace industry, but also in all aspects of transportation. The MATCH project is gaining support due to
    its relevance in today’s society.

    The MATCH project is centered on three primary goals:
       1. Modify a model turbojet engine to operate solely on gaseous hydrogen
       2. Design a radio-controlled aircraft to be powered by the aforementioned engine
       3. Construct the aircraft and integrate the converted engine into the aircraft

    The most important criterion for determining the success of the project is to complete the conversion
    of the model turbojet engine. The design of the aircraft, capable of housing the converted engine
    and power system, is complete and construction began and culminated in the spring 2006 semester.
    Although not explicitly stated as a project goal, flight testing of the aircraft is scheduled for April 2006 in
    anticipation of a successful flight.
    The MATCH design team is working in conjunction with the National Center for Hydrogen Research
    (NCHR) at Florida Institute of Technology. The center was recently founded and funded through a grant
    from NASA. To date, the center has worked on projects in safe storage, leak detection, fuel cells and
    internal combustion using hydrogen. One of the many products NCHR has completed is a small boat
    powered by an engine converted to operate on hydrogen.
    The completion of the MATCH project will enhance the profile of, and encourage further research in,
    the use of hydrogen as a viable fuel as well as expand our knowledge in turbo machinery, hydrogen
    combustion and aircraft design and construction, while helping us to create more reliable and efficient
    transportation.

    plan to do this by building a coil gun to
    launch a projectile with a muzzle velocity
    of 150 ft/s (45 m/s). A coil gun works
    by creating a current through the coils
    to which the ferromagnetic projectile
    is attracted. Due to this attraction, the
    projectile is then launched through the
    barrel towards the target.

Virtual Florida Institute of Technology
Project Team: Thomas Bedran, Team Leader; Scott Pio, Modeler; PJ Pittle,
Programmer

Faculty Adviser: Dr. William Shoaff

Mission Statement:
The Virtual Florida Institute of Technology Project will deliver
a realistic and interactive three dimensional computer
rendering of the Florida Tech campus.

Project Description:
VFIT will pioneer a new area of marketing by creating a fully interactive informational tool. The user will
be able to fully interact and explore the entirety of the Florida Tech campus from dorms to classrooms.
VFIT will compliment live tours regularly offered by Admissions for perspective students so perspective
students can come prepared to tours already knowing which aspects of campus they want to see.
Perspective students will also be able to use VFIT to gain additional knowledge about campus facilities
they learned about after taking a live tour. Furthermore, VFIT will be able to provide more information
than a regular tour by allowing students to interact with the campus; viewing the complete inventory
of sporting equipment available in Clemente, viewing menus for dining services, and where to go in the
library to pick up an interlibrary loan.
Dorm selection will be more relevant as perspective students will be able to tour rooms from each of the
resident halls and know the location of each hall relative to campus. Students will come to campus with
a working layout of where classes are held and where specific services are offered. If they have questions
about where a building is located, VFIT can provide them with directions.
The VFIT team will create a custom modeler, taking input from a 3D Studio Max file and embedding
custom interactivity. Modeled objects will be capable of interacting with the User Interface by displaying
text highlighting use or services offered, playing an auditory narration or launching a video clip. The User
Interface will have a listening interface designed to receive requests from modeled objects and then
render content.
The models are inputted into the VFIT engine which runs the interactivity experience. The engine will be
responsible for rendering the world and providing mechanisms for the user to move through out. At the
core is the irrlicht (http://irrlicht.sourceforge.net), a freely distributed open source 3D rendering engine,
which will provide basic 3D functionality. However, interactivity functionality will be the responsibility of
the VFIT team and will be built into the front end of the engine.

Faculty Activity Management System
Project Team: Ben Hanzl, Justin Kelley

Adviser: Dr. William Shoaff

Project Description:
The purpose of this project is to create a faculty activity tracking solution. Per the vice president for
academic affairs, each faculty member must turn in, as a minimum work assignment, 15 academic
credits or the equivalent per semester. Currently the formula for calculating this workload is manual,
time consuming and prone to oversight. By leveraging the power of the Web, we are creating a dynamic,
interactive Web site that provides input screens to the department head allowing them to enter course
and evaluation formula (based on established criteria) information. After the general information has
been entered, the faculty members would then login and enter details concerning their activities. The
department head and each member of the faculty can then run reports and view real-time workload
information. A sound judgment of performance can then be made regarding their workload versus the
expectations of their responsibilities.

Tasks Required:
   • Analyze faculty activity documentation
   • Identify data elements
   • Design database schema
   • Incorporate business rules into query objects
   • Layout Web server architecture
   • Build the Web interface
   • Test and debug Web interface
   • Document the final solution

Expected Outcome:
The expected outcome for this project is having faculty activity reporting at the
fingertips of the department head. As a result, time will be consolidated and the head will have more
available time for planning department strategy and doing things more valuable from a time
management perspective. This project will demonstrate teamwork, application of Software
Development Life Cycle techniques and software development skills that leverage HTML, PHP, mySQL
and UNIX/Apache.

Design of Software that Creates and Executes Petri Nets

Project Team: Todd Hoover, Steven Decker, Steven Nguyen, Aseem Parikh

Project Description:
The purpose to this project is to design a software package that will allow users have hands-on
experience in creating and executing a Petri Net. This allows users to be able to dynamically visualize
how Petri Nets can be used to solve complex problems in both operating systems and network systems.
The software will also allow the user to view a reachability tree that shows all the paths that the Petri
Net can take from a given marking. The project will be finished and submitted to Dr. Bond for use in his
operating systems class.

Tasks Required:
   • Implement GUI
   • Implement Core
   • Create System Requirements
   • Create a Workable Reachability Tree for Petri Nets

Expected Outcome:
Following the completion of this project, Dr. Bond will be able to use this software to help aid him in
teaching Petri Nets in his operating systems class. It will give the students the opportunity to see the
Petri Nets being created and in action instead of seeing it done by hand.

Network Visualization Tool Kit
Project Team: Michael Tremarche, Curtis Pettit, Tommy Walsh, George Francis,
James Lucas, Juliana Veloso, Josh Ohana, Alberto Duenas

Project Adviser: Monte Hancock, Essex Corp.

Problem:
In recent years, computer networks have increased greatly in both size and complexity. With these
increases, there has also been a substantial increase in both the number and complexity of malicious
attacks. Many large organizations that find themselves victims of malicious network attacks feel the
need to monitor their network traffic, in an attempt to determine the source of these attacks and to try
to stop them from happening. However, it can be difficult to spot patterns in network traffic by looking
at the packet information alone, and there are currently no simple, efficient tools to monitor and classify
network traffic.

Project Description:
The Network Visualization Tool Kit (NVTK) is an N-dimensional visualizer that we’ve created for use
by an entry-level analyst for monitoring network traffic. The visualizer allows the user to view an n-
dimensional object, such as a network packet, as part of a 3-dimensional graph. When represented in
the fashion, commonalities in specific types of network traffic, such as specific types of malicious attacks,
cause all of the packets from the attack to appear within a small space on the graph. This would allow
an analyst viewing the graph to recognize that the packets are all of a similar type, and that they should
be examined closer. The 3-dimensional graph produced by the NVTK requires the use of red/blue 3-D
glasses to achieve a true sense of depth in the graph. The NVTK also provides conversion functionality
from the graph file format to a spreadsheet format and vice versa, so the user can create graphs using
data from the visualizer and use the visualizer to view spreadsheet data if desired.

    OnePlus Monitor
    Project Team: Melissa Heater, Peter Nied, Mark Oldytowski

    Project Adviser: Dr. Philip Bernhard

    Project Description:
    The purpose of this project is to design an easy to use, yet robust utility that will monitor the up-ness of
    multiple servers and services. The utility will record performance and history of the servers and services
    and will notify system administrators when problems occur. The problems with current competitor’s
    products are cost, limited interfaces and difficult setup and use. We aimed to solve these problems by
    making the installation of OnePlus Monitor as simple as possible while still providing the necessary
    functionality that the user would expect through two separate but similar interfaces. This design
    will appeal to large businesses with multiple servers, small businesses that rely on web servers and
    individuals with online-based businesses. As to provide cross-platform support (Windows/Unix/Linux)
    and to provide compatibility with slightly older systems, we created the Core Service and Administrator
    Toolbox in Java 1.4.2, as it has been available for sometime and is found on most computer systems
    made in the last few years.

    Project Breakdown:
       • Core Service
       • Performs monitoring and logging operations
       • Serves data to the Administrator Toolbox and Remote Viewer
       • Holds setup information about logged servers
       • Able to run on server or directly on client machine
       • Administrator Toolbox
       • Graphical User Interface run on client machine
       • Allows changes to be made to Core Service
       • Provides a view of the server(s) and service(s) status(es)
       • Provides a view of the performance logs
       • Remote Viewer
       • Web-based viewer that can be accessed anywhere
       • Allows remote viewing without ability to make changes
       • Provides a view of the server(s) and service(s) status(es)
       • Provides a view of the performance logs

Expected Outcome:
After completing this project, members of our team will be showing it to our employers for possible
implementation in an actual work environment. This will supply us with practical test data as well as
potential customers if we decide to sell the product. We feel that this product would also be a good
additional layer of notification for Florida Tech to add to its network system to help decrease downtime of
its servers.

    The MAGNA Project
    Project Team: Jacek Leowski, Sam Oswald, Derek Pryor

    Project Adviser: Dr. William Allen

    Project Description:
    Concept—A Web server is a computer or group of computers that provides services over the Internet,
    such as retrieving Web pages or providing versatile storage space. They are also the targets of millions
    of attacks per year, both because of their importance as the backbone for the Internet and for sensitive
    information that many of them hold (such as usernames, passwords, credit card information, etc).
    TrendMicro is reporting losses from security exploits of as much as $55 billion in 2003, up from $33 billion
    in 2002 and $12.5 billion in 2001. While the style and stealth of these attacks is widespread and variant,
    what we can expect is that these attacks are growing in magnitude and current security systems are
    faltering and slow to react to change.
    Servers employ many different methods to protect their data and maintain their ability to fill clients’
    requests. As part of their internal structure, they use permissions and user groups, which are methods of
    locking down the file system to ensure that each user can only see the information that they are allowed
    to see. However, these methods can be subverted, and do nothing to protect the server’s other key point,
    maintaining its ability to serve users.
    To monitor activity by users and the connections they make to the server, an Intrusion Detection System,
    or IDS, is used. This is a complicated application set that can be described as a virtual security guard that
    monitors all of the doors into the server and keeps an eye on what users do while they are there. IDSs are
    typically adaptive, what we call passive IDSs, and monitor traffic to eventually learn patterns of movement
    that are malicious. There are also IDSs that take an active approach, and are hard-coded with various
    different patterns to notice and a retaliation to initiate once a pattern is found.
    Just like a real security guard, this is a very difficult job. How do you know if someone is acting suspiciously
    or if they just don’t know what they are doing? What if an attacker does something before you can catch
    them? How do you find and undo the damage? What can you do if someone is attacking you? Is there
    any way to stop them? And as difficult as that sounds, now
    imagine that you are the security guard for a corporation
    like Amazon.com, with almost 50 million user accounts, not
    to mention the multitude of programs and unregistered
    visitors that access the servers. This is a lot of potential
    traffic to monitor.
    Oftentimes, the ability of IDSs depends much upon the
    attacks we already know about or have identified. It is
    difficult to determine what suspicious behavior is until
    we can repeatedly identify it and tell how dangerous it is.
    This takes time and much risk, especially since the                            The Project Overview

The MAGNA Project
observation process requires a live environment with real users connecting to use the server. Why a live
environment? Well, how else can an IDS observe what customers on a Web site will do, especially what,
say, 10 million customers on a Web site will do. Naturally, in the case of passive IDSs, this also introduces
the problem of guaranteeing that the normal traffic an IDS is observing is actually normal. What if the
IDS is observing large amounts of attack traffic, but because it doesn’t yet realize they are attacks, it
simply decides the attacks appear to be common user actions and allows them to continue (and more
dangerously, perhaps classifies the normal traffic as malicious).
The MAGNA project is an active approach to improving the quality of IDSs and therefore the security
of Web servers. Using a repository of attacks, MAGNA delivers a known group of attacks to a test server
and its IDS in a closed environment, so that server developers and network administrators can monitor
the effectiveness of the IDS in repelling the attacks and the server’s ability to recover. The tester can
choose any number and combination of attacks, as well as patterns for how and when the attacks are
run, and MAGNA will realistically deliver the attacks while logging relevant information (such as response
messages from the server).
In this way, the MAGNA project serves a dual purpose. First, as said earlier, to actively test a server’s
security. Second, it serves as a collection of attacks that shows how attacks work, how different attacks
are related and allow developers a greater opportunity to see how attacks may evolve so that they can
prepare for them.


Components of the MAGNA Project
There are three components of the MAGNA project, a repository to document attacks, an editor to view
and manipulate attacks and an attack generator to launch attacks.

The Attack Generator
The Attack Generator is the core of the MAGNA project, as it is the component that makes the other
two necessary. The purpose of the attack generator is to deliver any number of attacks in any variation
of patterns to a server to examine the effectiveness of the server’s intrusion detection system and
the ability of the server to either withstand or recover from the attacks. It is, in short, a testing tool for
evaluating server security.
The Attack Generator is composed of python scripts, making it lightweight, fast and most importantly,
entirely portable. It is command-line based so that it can be run from anywhere. For example, a system
administrator could deliver the attacks from multiple different computers by launching the Attack
Generators and controlling them remotely from a master computer.
The job of the Attack Generator is to parse a file describing an attack and create a state table of motions
through the attack. A list of needed packets is read, and the Attack Generator assembles the packet
headers and payloads into memory. The generator then walks through the states of the attack and
delivers packets to the server as needed.

    AES: The Attack Editing System
    The AES is a java-based GUI that allows a user to create, view and edit attacks. It is tab-based,
    allowing a user to view and edit multiple attacks, or look at one attack to help write another. The AES
    also allows a user to examine the components of an attack to help understand how to further improve a
    security system, by truly understanding where and what
    an attack is targeting.

    The Attack Repository
    The attack repository is a MySQL database that stores
    information about the attacks. The information stored
    includes the motions of the attack (the states), the family
    and relational data about the attack, and discovery/
    release dates. Each attack is also assigned an identification
    number that allows us to quickly sort and analyze the
    attacks.

Image Map Editor
Project Team: Matthew Moisan, Noble Hurst

Project Advisers: Sharon Ainsley, Dr. William Shoaff

Project Description:
The purpose of this project is to create a tool that will function as a GUI to ease the process of creating
image maps in HTML. It will allow for an interactive method of creating the hyperlinked regions as well as
associating those points with a table in a database that will store information for each region. The product
of the editor is a PHP/HTML interactive image map, which will show information from a database table.

The project is made up of two major parts, the editor and the database. There are a few classes that
were created to facilitate the communication of the database and editor as well as allowing many of
the features that we have been able to implement into this project. This project utilizes knowledge in
database communication, security, Web development, GUI design and an understanding of project
management.

This project was initially created to provide an interface to create an easily updatable map of the campus.
With the features we have added and the opportunity to easily add more functionality has made our
project something that can be used in situations other than the school’s map, including but not limited to
charting stars and describing parts of the body.

    Adaptive Web Personalization Research
    Project Team: Chris Tanner

    Project Adviser: Dr. Philip Chan

    Abstract:
    Our research will allow for more accurate and effective navigation of the World Wide Web. Specifically,
    most current search engines generalize all users as being the same. Thus, if a computer scientist searches
    for “windows” and a carpenter searches for “windows,” they will receive the same page results. However,
    the computer scientist was seeking information on the operating system and the carpenter wanted to
    buy glass panels through which to look. So it would be useful if the search engine knew this and could
    appropriately cater to the users.

    We attempt to solve these issues by developing novel, nonintrusive techniques for a more adaptive and
    personalized Web. Personalized techniques cater to specific users, rather than generalizing all Web users
    as being the same. Adaptive methods learn from the users’ potentially changing behavior/interests.
    Nonintrusive techniques implicitly learn and do not require users to explicitly indicate their interests.
    Our created system uses these techniques and ranks Web pages in respect to how interesting they are
    to a given user. Thus, the research allows for a multitude of applications: developing a search engine,
    pre-caching pages that the user will likely visit, suggesting other pages/products the user might be
    interested in, etc.

    Tasks:
       • Read past research papers by Dr. Chan and Dr. Hyoung-rae Kim
       • Fully implement past software
       • Create new, novel ideas that have sound motivation and reasoning
       • Test ideas to see if better results are obtained
       • Write results in hopes of being published

    Basic Overview of the System:
    We learn a user’s interests from a user’s bookmarked Web pages. Having built a structure that represents
    what the user is interested in, we can evaluate and rank new Web pages to predict how interesting it will
    be to the user.

Adaptive Web Personalization Research
Current Experiment and Results:
To quantitatively measure how well our system performs, we conducted an experiment with 11 users
surfing the Internet for a few hours. Users rated Web pages in respect to how interesting they found them.
Our system ranked these pages in hopes of correctly predicting what the user would find interesting. We
create diagrams to illustrate how precise our predictions are, along with how many interesting pages we
were able to recall. The following diagrams show that we outperformed Google, as our algorithms yielded
results with higher precision and recall values.
(Note: “ws” represents our Weighted Scoring algorithm, and “uws” represents our Unweighted Scoring algorithm. Lines having values closer to the upper-right hand corner of the
graph represent better results.)

    Stereo Vision Library

    Project Team: Ahmed Charles, Clayton Gilmore

    Project Description:
    The purpose for this project is to develop C++ libraries for virtual reality modeling. The idea is that an end
    user with a VR display, a Web cam and these libraries would be able to model 3D geometric objects and
    view them through the VR display, with the view generated based on where the user is looking.

    What we propose is a two-part project. The first part is to take an existing ray-tracer program developed
    for a Computer Graphics Algorithms project and make it run faster as well as produce stereo pairs.
    The second part is to write a program that tracks head movement using input from a Web cam. It is
    envisioned that the first part will be completed for Software Development Projects one in the fall
    semester, and part two for Software Development Projects 2 in the spring semester. When both parts are
    completed, these will be packaged together as libraries.

    Tasks Required:
       • Expand Raytracer to Produce Stereo Pairs
       • Expand Number of 3D Objects Supported
       • Improve Efficiency of Raytracer
       • Design and Program the Web Cam Interface
       • Design and Program Head Tracking Algorithm
       • Couple the Raytracer and the Head Tracker Together

    Expected Outcome:
    Following the completion of this project, the design team would like to release the software libraries
    under an open source license. It would be an excellent tool for learning about computer vision.

    Program Assessment

    Project Team: Kyle Wheeler

    Project Adviser: Dr. William Shoaff

    Project Description:
    The purpose of this project is to develop a software system that will assess students, courses and
    programs in a variety of course and program objectives. The system will be composed of a database,
    the core code and a user GUI. The database will store programs, objectives, students, courses and their
    respective scores. The core code will allow users with given privileges the ability to view and/or update
    the database. Finally, the GUI will provide students and faculty with an easy to use tool for viewing and
    updating data.

    Tasks Required:
       • Database
       • Database Access Based on Privileges
       • Front End Client (GUI)
       • Tracks to GUI Link

    Expected Outcome:
    The expected outcome of this project is a useable system which the faculty can use to assess students,
    courses and programs. It is expected to provide a means for Florida Tech to demonstrate its abilities as
    well as provide professors and students with a general idea of each student’s strong and weak points.
