(Rensselaer civil engineering students shared some thoughts about their experience at the 2014 Geo-Wall competition, held this February in Atlanta by the American Society of Civil Engineers. The Rensselaer team placed third!)

Every year, Rensselaer Professor Tarek Abdoun encourages his students to form a team and participate in the GeoWall competition, which is held annually at the American Society of Civil Engineers (ASCE) GeoCongress conference.

The first step is for teams to submit a report describing their design of an earth retaining wall that is built using specific materials, is mechanically stable, and can sustain multiple loading phases. The competition parameters change from year to year, and this year required a rubber-sand mixture for backfill instead of regular sand. The Rensselaer team developed their model, made from the backfill, paper strips, and other materials, and tested it in the Institute’s soil mechanics lab. Following rough geotechnical calculations and engineering judgment, a simplified numerical model was developed to verify the design.

After submitting the report, the Rensselaer team was informed it ranked 4th and was invited to compete in Atlanta on February 24. Based on the quality of their report, the team also received a $2,000 grant for their traveling expenses.

The team members, all civil engineering students, reflected on their experience.


Rensselaer medical bridagers learn to take patient vitals

(Rensselaer senior Lynnette Lacek and junior Colleen Lamberson, co-presidents of university’s chapter of the Global Medical Brigades, wrote this guest post about their recent work in Panama.)

In January, Rensselaer’s chapter of Global Medical Brigades traveled to the Darien Province in Panama to provide medical care to the indigenous Embera and Wounaan tribes. It was an amazing opportunity – for three days our small group of 21 students functioned as a mobile medical unit.  We set up a small clinic in the local community center, and with the help of two doctors, one dentist, and one pharmacist, we were able to diagnose and treat 373 patients.


Rensselaer professor Eddie Ade Knowles will be featured in a documentary about renowned jazz and soul artist Gil Scott-Heron airing Wednesday night.

Knowles, an accomplished drummer, was a member of Gil Scott-Heron and the Midnight Band in the 1970s. He played the conga drums that were the beat behind one of Scott-Heron’s most notable works, “The Revolution Will Not Be Televised.”

“(Scott-Heron) had never done poetry with drums and so we spent some time in terms of how to do this with conga drums being played,” Knowles says in a preview of the documentary.

The documentary “Unsung: Gil Scott-Heron” airs at 10 p.m. Wednesday, Feb. 12, on TV One, channel 184 on Time Warner Cable locally.

UPDATE 2/12:


On Lake George, from the deck of the survey ship Mintaka, the threat to boats cruising past Shelving Rock near The Narrows is apparent in high resolution detail. Lurking beneath the water, where charts indicate consistent (if shallow) water, are intermittent formations of jagged hull-ripping rock ledge. Although the educated boater would be warned from these shores by well-placed channel markers, the moral of the story stands: there’s a lot we still don’t know about Lake George.

In the coming years we are going to learn a great deal more, thanks to the Jefferson Project at Lake George, a multi-million dollar collaboration between RPI, IBM, and the FUND for Lake George that will develop a suite of new technologies and techniques to revolutionize environmental monitoring.


(Rensselaer civil engineering doctoral student Jingjing Tian iwrote this post about her experience at a huge shake-table experiment she and her adviser, Professor Michael Symans, attended last year. They are part of a multi-university research project dedicated to making buildings more resilient to earthquakes.)

A full-scale, multi-story wood-framed building with soft ground story was constructed and tested during this past summer at the NEES (Network for Earthquake Engineering Simulation) Laboratory at the University of California, San Diego (UCSD), as part of the NSF-sponsored NEES-Soft project. The project focuses on seismic performance of multi-story buildings with weak (soft) ground stories. The test specimen was designed and constructed to resemble the architectural and structural characteristics of soft-story residential buildings located in high-seismicity regions of the western United States (see a comparison below).


3° with with Emily Liu

by Michael Mullaney on December 20, 2013

Nuclear engineering expert Emily Liu is an associate professor in the Department of Mechanical, Aerospace, and Nuclear Engineering at Rensselaer. We ask Emily about her work:

Q: Your research is fascinating! It spans from nanomaterials, to radiation damage, to nuclear threat detection. What is the overall problem you are trying to solve?

A: My research targets a fundamental problem: How do we link nanoscale observations with macroscale phenomena? In our lab, we utilize laws from physics combined with experiments and simulations to explore this question. The answers we find will be very beneficial for designing and modifying new nano- or macroscale materials, as well as biological or chemical functions.

Outside of the lab and the classroom, what do you like to do for fun?

Many things. I especially like reading books and exercising. When it’s warm, I am fascinated by taking my kids swimming, rafting, and horseback riding.

What kind of music do you like?

Half of the time, I like romantic and soothing pop music such as the song “I Hope You Dance” by Lee Ann Womack. However, when I am excited or very happy, I enjoy rock music a lot.


If you wanted to learn to speak Chinese – really speak Chinese at a level that allowed you to converse with native speakers at a high level and conduct business in China – you’d have to go to China, right?

Not necessarily, thanks to the work of some Rensselaer Polytechnic Institute professors.

They’re working to create the next generation of language education – a hybrid of immersive classroom experiences and virtual reality adventures designed to grab students’ attention and keep it as they master Chinese.

Teaching a foreign language, especially one as difficult for native English speakers as Chinese, is a particularly thorny problem. Listening, speaking, reading, and writing are all crucial components, but so is the cultural context in which the language is spoken or written.


A New Kind of Princess

The princesses on campus last weekend weren’t waiting around in a tower to be rescued by a prince. They weren’t tripping over their own glass slippers on the way home from a fancy ball. And they certainly weren’t sleeping, waiting for a magical kiss to wake them.

These princesses — Eco Princesses, actually — were all about action. They learned about sustainable energy and recycling, composting, and water pollution. They learned that while they may only be pretend princesses (or princes, as the case may be) they really can be masters of their own universe.


My Night With SOFIA

by Mary Martialay on November 14, 2013

Daniel Angerhausen celebrates his flight aboard SOFIA

(We’ve been following Daniel Angerhausen, a postdoctoral fellow in the Department of Physics, Applied Physics, and Astronomy, in his quest to conduct research aboard NASA’s flying observatory, SOFIA. From anticipation in April, to disappointment in May, we are pleased to at last report success and joy. Congratulations Daniel!)

“So I spent the night at 42,000 feet on a billion dollar NASA aircraft observing an alien world 63 light-years away. How was your night?” — Tweet from Daniel the morning after his very first flight on the Stratospheric Observatory for Infrared Astronomy (SOFIA).

I finally did it: I flew on SOFIA — and it was truly amazing.


Archies reImagining miSci

by Emily Donohue on November 12, 2013

I grew up in Schenectady and as a kid one of my favorite Electric City excursions was a trip to the science museum and, even better, the planetarium it contained. I have fond memories of snuggling into the reclining planetarium chairs and watching as stars, planets and constellations were pointed out, visiting the museum’s optical illusion exhibit and trying, often in vain, to see the old woman within what looked to me like simply a picture of a young woman. Touching the Van de Graafe generator that made my hair stand on end was another classic museum experience.

After nearly two decades, I visited the museum — now called miSci — again last week and it’s grown up a lot. miSci features even more interactive, hands-on exhibits and some very cool artifacts highlighting Schenectady’s history in technological innovation.
