Walking into the turbomachinery lab on the lower level of the University of Hartford’s Dana Hall, you can feel the excitement and happiness of eight mechanical engineering students there. They have spent the last two years building a wind tunnel in the lab. Now, they are finally able to unveil it and use it to conduct research that will be useful to the aerospace industry.
“You have no idea how exciting this is,” says Mark Markiewicz ’18, who joined the project as a first-year student in the College of Engineering, Technology, and Architecture (CETA). The wind tunnel allows Mark and his teammates to study and measure key aspects of aerodynamics. They expect that their findings will make jet engines’ turbines and blades more efficient and help aerospace companies save millions of dollars. The research may also benefit power plants which rely on turbines.
The opportunity to do research using this type of equipment is typically reserved for graduate students at other universities but this team is made up of undergraduates selected by CETA mechanical engineering professor Ivana Milanovic. Milanovic made Mark, who is a sophomore, the project lead after he impressed her with his analytical and supervisory skills. Although she remains involved to provide oversight and mentorship, Professor Milanovic lets Mark and his classmates make daily decisions to ensure everything is done properly.
Gianna Sabino ’16, who was brought on to the project in the summer of 2015, learned a lot from working on the build and the research, so much so that it helped her get a job. She will start working for Pratt and Whitney in June conducting tests on wind tunnels.
“The teamwork aspect and leadership skills will definitely come in handy when I start my job,” says Gianna.
Walking or driving on campus near Lincoln Theater or the Konover Campus Center these days prompts the question “What are those little buildings over there on the grass?” Assistant Professor Seth Holmes teaches architecture in the University’s College of Engineering, Technology, and Architecture and can explain what they are:
Holmes’ graduate architecture students are using the huts to learn how to design energy-efficient buildings. They learned techniques first in the classroom and then put those lessons into practice on campus.
“We got hands-on experience with the building systems,” explains Lance Green M‘17 who also had Holmes as a professor as an undergraduate. “We saw how all the components interact with each other and how they all function. It is definitely better than reading a textbook.”
Fahed Baker and Alyssa Danielwicz, also first-year architecture graduate students, are particularly interested in the data they collected from the buildings.
“We’ve been gathering temperature and humidity levels using a technology available right on our phones.” says Fahed. “I think it went well and we learned a lot of things.”
“That was the most rewarding part for me,” Alyssa agrees. “Seeing the data and significant results from the different methods that we used to build the huts, that was cool.”
Evan Switzer M’17 says the project will have practical implications in the workplace.
“We can take the data from these small scale projects and apply them to larger buildings,” he says. “We are learning how to naturally achieve comfortable temperatures on the inside of buildings without the help of machines to heat and cool the buildings.”
“At UHart they just give you the tools to start whatever you want,” says Hugo Santana ’16. He speaks from experience. In just four years, Hugo has taken full advantage of stude
nt life on campus. He helped organize and presented during the University’s first TEDx Talk and started his own soccer club. He worked as an ambassador and a tour guide for the University’s Department of International Admission and as a math tutor. He also hosted his own radio show on the student-run radio station. And yes, there’s more— he is working with Akin Tatoglu, assistant professor of mechanical engineering in the University’s College of Engineering, Technology, and Architecture, to design a device that enables photographers to take clear pictures even when their hands are moving.
When it comes to treating severe bleeding injuries, every moment counts. That is why Frank Hursey ’77 invented QuikClot, a type of gauze that stops bleeding practically on contact. This gauze, which has saved thousands of lives in hospitals and war zones around the world, is also found in bleeding control kits that University Public Safety officers now carry on campus.
Patricia Mellodge, associate professor of electrical and computer
engineering in CETA, has had her latest book published, A Practical Approach to Dynamical Systems for Engineers, by Woodhead Publishing, November 2015.
Mellodge’s third book takes the abstract mathematical concepts behind dynamical systems and applies them to real-world systems, such as a car traveling down the road, the ripples caused by throwing a pebble into a pond, and a clock pendulum swinging back and forth. Topics covered include modeling systems using differential equations, transfer f
unctions, state-space representation, Hamiltonian systems, stability and equilibrium, and nonlinear system characteristics with examples including chaos, bifurcation, and limit cycles. MATLAB and Simulink are used throughout to apply the analysis methods and illustrate the ideas.
Applications in engineering are used to show the adoption of dynamical system analytical methods. Examples are provided on the dynamics of automobiles, aircraft, and human balance, among others, with an emphasis on physical engineering systems.
Mellodge’s previous books are: P. Mellodge and P. Kachroo, Model Abstraction in Dynamical Systems: Application to Mobile Robot Control, Springer, October 2008; and P. Kachroo and P. Mellodge, Mobile Robotic Car Design, McGraw-Hill, August 2004.
The Hartford Scholars Program at the University of Hartford made it possible for Greg Beebe ’92 to change the course of his life. He grew up poor in inner-city Hartford with no male role models, in a family where no one had graduated from high school.
Beebe’s family changed apartments frequently because money was tight (they even lived in a mote
l for a while). Food stamps and government cheese were staples. But Beebe knew at a young age that he had goals: to earn twice his age times 1,000 at age 30, reach six figures by age 40, and become a company president by age 50. He has done all that — and more.
An entertaining outing for Beebe’s family was a trip to the grocery store followed by a picnic lunch while parked at Bradley Airport, watching planes take off and land. He loved camping, and the Boy Scouts provided opportunities for leadership and tutelage. Scouting helped Beebe to focus on his goals, with no distractions. He soon achieved the top prize: Eagle Scout.
A girlfriend recognized Beebe’s interest in electronics as he spent time building a stereo system pieced together from junk parts. She pressed him to pursue an engineering education at the University of Hartford, where she intended to study. On a visit to campus, Beebe sat in on a DC Electrical Fundamentals class at the Ward School of Technology (now the College of Engineering, Technology, and Architecture), talked with the dean and then his advisor, all of which
helped him realize that electronic engineering technology was a good fit.
Beebe believes that attaining Eagle Scout gave him a huge edge over another candidate holding equivalent qualifications when he applied for his first job at Sennheiser Electronics, a German company specializing in the design and production of a wide range of audio electronics for consumer, professional, and business uses. Over more than 23 years at Sennheiser, Beebe learned three things: he enjoys internationalism, challenges, and building teams. His purpose in life is to nurture others so they can grow. He feels fortunate to have been in a multi-year training program at Sennheiser, which primed him for varied domestic and international leadership roles. He headed sales and marketing in four different countries simultaneously, which required frequent contact with partners in Turkey, Greece, Spain, and Portugal. His role as VP for business in Latin America not only fueled his interest in internationalism and team-building, but has lead to lifelong friendships.

Beebe sees the many steps in his life as blessings. “This doesn’t happen to a person who ate government cheese,” he says. He believes that when he set his life goals at 13, somebody upstairs was listening.
