Nagurney Publishes on FirstNet and Emergency Communications in The Conversation

Ladimer S. Nagurney, Professor of Electrical, Computer, and Biomedical Engineering in CETA, has had the article, FirstNet for emergency communications: 6 questions answered, published in The Conversation. The article describes the new wireless broadband communications network currently being deployed in the US for first responders' use during emergency and disaster situations. FirstNet is one of the largest Public Private Partnerships ever undertaken in the US.

The article has been reprinted in several new outlets including the Stamford (CT) Advocate, Danbury News-Times, the Albany Times-Union, the San Francisco Chronicle (SFGate), the Idaho Press-Tribune, and the Skagit (WA) Valley Herald.

Professor Nagurney's co-author is Professor Anna Nagurney of the Isenberg School of Management at UMass Amherst.

UHart and the Solar Eclipse: NASA CTSGC Leadership Team Shares Ways to Get Involved


The NASA CTSGC (Connecticut Space Grant Consortium) leadership team is very excited for Monday’s solar eclipse. We have been quite busy organizing several activities associated with this once-in-a-lifetime event, which we hope you will consider engaging with.

Eclipse Ballooning Project:  The NASA CTSGC team, comprised of students and faculty from University of Bridgeport and University of Hartford, will launch high altitude balloons that engage in three separate activities: (a) NASA experiment to study extreme weather conditions, (b) measure climate conditions during an eclipse using radiosondes, and (c) livestream the solar eclipse. The balloons, which will be launched from Paducah, Kentucky, are expected to reach an altitude of up to 100,000 during the solar eclipse.

Here’s how you can watch:
Livestreams:
NASA TV will have a 4-hour special on the day of the eclipse which includes live reporting across the path of totality throughout the US: https://eclipse2017.nasa.gov/eclipse-live-stream

Milanovic Presents at NASA GRC Meetings



The 4-strut nozzle: pressure iso-surfaces.

Ivana Milanovic, professor of mechanical engineering in CETA, successfully completed the NASA Glenn Faculty Fellowship 2017. Fellowship was hosted by the Propulsion Division and the duration of tenure was 10 weeks. Milanovic’s research focused on the acoustic resonance ‘modes’ and ‘standing waves’ related to the resonance that lead to methods for suppression or avoidance of such tones in aircraft engines. Milanovic presented her collaborative research in the following NASA GRC meetings:
  • Inlets & Nozzles Branch Meeting on August 10. The title of the presentation was ‘Resonance & Tones in Multi-Stream Nozzle Flows.’
  • Transformational Tools and Technology (TTT) & Commercial Supersonic Technology (CST) Project Meeting on August 9. The title of the presentation was ‘Investigation of Tones with Multi-Stream Nozzles.’
  • 2017 NASA Glenn Research Day Poster Session on July 28, Cleveland, OH. The title of the poster was ‘Resonance & Tones in Flow.’
Research has been done in collaboration with Khairul Zaman, Inlets & Nozzles Branch, and  Christopher Miller, Acoustics Branch of NASA Glenn Research Center. The project studied numerically multi-stream nozzle flows and associated resonance phenomena. Numerical results were validated with experimental data obtained in open jet facilities and wind tunnels. This research was also featured in NASA GRC Highlight on Nozzle Flow/Acoustic Simulation.

Students, Professors, and Scientists Practice Balloon Launch in Preparation for Total Solar Eclipse

Our Lessons Launch Futures

“Three… two… one… liftoff” was heard on a University of Hartford athletics field as a team of University of Hartford and University of Bridgeport students released an eight-foot tall helium-filled weather balloon on August 9. The launch was a practice run for a launch on Aug. 21 that will enable millions of people  to see a once-in-a lifetime solar eclipse across the United States.



Two UHart students and three professors are part of the team, which is working with the NASA Connecticut Space Grant Consortium (CTSGC). A total of 55 teams are participating in the eclipse live stream, capturing video along the path of totality, from the Pacific coast in Oregon to the Atlantic coast in South Carolina. The moon is expected to completely cover the sun for approximately two minutes.

“Today’s objective is for the students to be the leaders in this dry run, so we’re essentially here as spectators. They’re in charge,” said Assistant Professor Mary Arico.
 
The Connecticut team’s balloon will be based at Kenlake Resort in Hardin, KY, near the spot where the eclipse is expected to be in totality for the longest amount of time. They will launch approximately 90 minutes prior to the eclipse, as they anticipate the balloon will climb an average of 1,000 feet per minute to reach an altitude of close to 100,000 feet. The balloon will carry a 12-pound payload consisting of a video camera, still camera, and GPS tracking system. This is part of a nationwide, NASA-sponsored initiative to live-stream aerial video footage of the solar eclipse.

UHart mechanical engineering major Mark Markiewicz ’18 said, “We’re testing today in preparation for the real event by following exact launch day procedures to trouble-shoot and anticipate any problems that might occur during those two minutes of darkness during the total eclipse. We also have to time it so that once the eclipse has passed, we can retrieve the balloon, which will have burst while the payload parachutes back to earth.”

“Today’s objective is for the students to be the leaders in this dry run, so we’re essentially here as spectators. They’re in charge,” said Assistant Professor of Civil and Biomedical Engineering and Associate Director of CTSGC, Mary Arico.

The students took the lead, and the launch into the atmosphere was considered a smooth one.

Team member and UHart mechanical engineering major Stefan Keilich ‘18 said the idea that “hundreds of millions of people” will be watching the broadcast is thrilling and “makes the inherent pressure of the project worth it.”

The practice launch was a learning experience and revealed some needed adjustments. “We learned that we’ve got to practice with our tracking system again and again until we perfect it,” said Mark. The practice balloon traveled over southeastern Massachusetts at an altitude higher than planned and went farther than the anticipated retrieval site in eastern Connecticut.

Live viewing of the eclipse will be available on NASA’s website, http://nasa.gov on August 21 beginning at 12 noon EDT. Follow on social media using #Eclipse2017CT.

NASA CTSGC, with UHart as its lead institution, is an affiliate of a federal grant, internship, and scholarship program funded as part of NASA's Office of Education designed to broaden the participation of universities and individuals in aerospace science, engineering, and technology.
