It is possible to predict the track of a hurricane with a reasonable degree of accuracy several days in advance. Unfortunately predicting intensity is less certain, and potential victims don’t know whether to expect a rather heavy thunderstorm or something truly apocalyptic. Evacuation may be a wise precautionary measure, but when the promised devastation does not occur it looks like crying wolf.

Researchers at the Southern Methodist University in Dallas, Texas are developing a new modelling technique to predict the speed of hurricane winds. Known as the Learning Prediction Intensity Interval model, it is based on data mining using an advanced machine learning process. The computer itself works out the pattern of intensity development from a large pool of raw data, unlike existing methods where humans cherry-pick the most relevant historical data for a regression model to fit the current situation.

KERA: Engineering Hope: Research To Aid Injured Troops

Reporter B.J. Austin with Dallas area Public Radio station KERA has interviewed SMU engineers Marc Christensen and Volkan Otugen who are working as part of a consortium with industry and other universities to develop technology that will someday help amputees have “feeling” in their artificial limbs.

The research is funded through a $5.6 million grant from the U.S. Department of Defense and industry for a center led by SMU’s Lyle School of Engineering. The goal is to develop revolutionary technology for advanced prosthetic limbs that will help amputees returning from war in Iraq and Afghanistan.

Two-way fiber optic communication between prosthetic limbs and peripheral nerves will be key to operating realistic robotic arms, legs and hands that not only move like the real thing, but also “feel” sensations like pressure and heat.

KERA’s coverage aired Oct. 10 as part of a larger series on “Engineering Hope: Groundbreaking Research That Could Change Our Lives..”

KERA News
This week, KERA 90.1 is airing a series of reports: “Engineering Hope: Groundbreaking Research That Could Change Our Lives.” In today’s report KERA’s BJ Austin visits a lab where researchers from North Texas universities are developing the next generation of prosthetic limbs for injured soldiers. It’s cutting-edge research that could allow amputees to move more naturally and sense feeling with their artificial limbs.

In a busy Starbucks, two things make 28 year old Clint Barkley stand out in the crowd: his clean cut good looks and his walk.

Barkley: We were just south of Fallujah in 2005. We ran over a land mine. I lost my left leg. Our gunner lost both of his feet below his knee.

The former Marine from Bedford walks unevenly, slightly stiff, but full of confidence. He wears a ten pound, titanium leg. It attaches mid-thigh and has a computerized knee.

Barkley: It reads your body weight, how you’re moving and it reacts accordingly. I put my heel down then as I go and put all the pressure in my toe it knows I’m taking a step so it releases and kicks the foot back forward for me.

But what it doesn’t do is allow a smooth, natural gait. And the leg does not allow him to feel the gravel in a driveway or the heat of an asphalt parking lot in August. But that could be in his future.

A consortium of scientists and engineers in North Texas and elsewhere are working on a way for the brain, the body’s nerve impulses and an artificial limb to “talk” to each other. That could allow an amputee to “think” about moving an artificial arm or leg and the limb would respond immediately and more naturally. Conversely, the artificial limb would talk to the brain, giving it sensory input, thereby allowing the amputee to “feel.” The research is being led by Marc Christensen, Professor of Engineering Innovation at Southern Methodist University. But, part of the project is taking place in a noisy, unassuming lab at the University of North Texas. That’s where Christensen talked about the research, being funded initially by a 5.5 million dollar grant from the Department of Defense.

Popular Science: A New Interface For Bionic Limbs

Light bridges the communication gap between man and machine

The monthly science magazine Popular Science covered the research of SMU engineers Marc Christensen and Volkan Otugen who are working to develop technology that will someday help amputees have “feeling” in their artificial limbs.

The research is funded through a $5.6 million grant from the U.S. Department of Defense and industry for a center led by SMU’s Lyle School of Engineering.

The Six Million Dollar Man’s robotic arm worked as seamlessly as his natural one. But in the real world, robotic limbs have limited motions and the user can’t feel what he or she is “touching.” a new approach using optical fibers implanted around nerves could transmit more data and let prosthetics speak to the brain.

Previously, scientists surgically connected electrodes to the nervous system, but they seemed to harm the body’s tissues, making the implant fail within months. In 2005, scientists discovered that they could stimulate a neuron to send a message by shining infrared light on it. Last September, DARPA, the Pentagon’s R&D branch, awarded $4 million to a project led by Southern Methodist University engineers to attempt to connect nerves to artificial limbs using fiber optics.

The team suspects that flexible glass or polymer fiber optics will be more flesh-friendly than rigid electrodes. In addition, optical fibers transmit several signals at once, carrying 10 times as much data as their electrical counterparts. “Our goal is to do for neural interfaces what fiber optics did for the telecom industry,” says electrical engineer Marc Christensen, who is leading the SMU group. Transmitting more information faster should give bionic limbs more lifelike movements.

SMU rises in Carnegie Foundation research classification to ‘high research activity’

The Carnegie Foundation for the Advancement of Teaching has raised SMU’s classification among institutions of higher education, reflecting dramatic growth in the University’s research activity since it was last measured in 2005.

SMU is now categorized as a research university with “high research activity,” a significant step up from its last assessment in 2005 as a doctoral/research university. The Carnegie Foundation assigns doctorate-granting institutions to categories based on a measure of research activity occurring at a particular period in time, basing these latest classifications on data from 2008-2009.

“SMU’s rise in the Carnegie classification system is further evidence of the growing quality and research productivity of our faculty. We are building a community of scholars asking and answering important research questions and making an impact on societal issues with their findings,” said SMU President R. Gerald Turner. “In addition to our dedication to outstanding teaching, SMU is becoming increasingly recognized as a vital resource for research in a variety of fields.”

Increased research activity in step with other SMU advances
“The designation of SMU as a ‘high research activity’ university by the Carnegie Foundation is an important step in SMU’s evolution as a strong national university,” said Paul Ludden, provost and vice president for academic affairs. “The faculty, staff, and students at SMU can be proud of this, particularly when paired with our rise in national rankings. The Carnegie Classification recognizes the tremendous efforts by the entire faculty at SMU to expand our research portfolio and address the many questions facing North Texas and the world. Recognition should go to Associate Vice President for Research James Quick and his office for their efforts to support the research activities of our faculty and staff.”

The foundation’s assessment of SMU’s increased research activity occurs as the University is making dramatic advances in other measures of academic progress: U.S. News and World Report magazine gave SMU its highest ranking ever for 2011, placing SMU 56th among 260 “best national universities” — up from 68th in 2010.

Additionally, SMU’s Cox School of Business is one of only a few schools in the nation to have all three of its MBA programs ranked among the top 15, according to Bloomberg Businessweek. Applications to SMU continue to rise, as have average SAT scores for admitted students.

Carnegie finds SMU research activity recorded an increase
The Carnegie Foundation analyzed SMU’s research activity in a category of universities that awarded at least 20 research doctorates in 2008-2009, excluding professional degrees such as those leading to the practice of medicine and law. The analysis examined research and development expenditures in science and engineering as well as in non-science and non-engineering fields; science and engineering research staff (postdoctoral appointees and other non-faculty research staff with doctorates); doctoral conferrals in the humanities, in the social sciences, in STEM (science, technology, engineering, and mathematics) fields, and in other areas such as, business, education, public policy and social work.

The Carnegie Foundation classification of U.S. accredited colleges and universities uses nationally available data from the U.S. Office of Postsecondary Education, the National Center for Education Statistics’ Integrated Postsecondary Education Data System (IPEDS), the National Science Foundation, and the College Board.

“SMU’s rise in academic rankings and research productivity is a strong return on the investment of our alumni and other donors who provide support for research, endowed chairs, and graduate programs and fellowships,” said SMU Board of Trustees Chair Caren Prothro. “SMU students at all levels are the beneficiaries of this distinction as their faculty enliven the classroom with their research and engage students in the tradition of academic inquiry.”

About the Carnegie Foundation for the Advancement of Teaching
Founded by industrialist Andrew Carnegie in 1905 and chartered the following year by an Act of Congress, the Carnegie Foundation for the Advancement of Teaching is an independent policy and research center. Its current mission is to support needed transformations in American education. — Kim Cobb

Imagine not being able to pick up a drink, a pen, or even hold a spouse’s hand. For thousands of North Texans living as amputees, that is reality. But, some local engineers are teaming up with medical science to help transform that reality and change lives.

Bernie Diamond of Fort Worth is the picture of health. The former fitness model turned hairdresser was on top of his game. But, three years ago, everything changed in a split second when he was randomly shot while standing outside a home in Dallas.

“I got shot at such a perfect angle that it shot through the wrist and blew out the entire back of my hand,” Diamond said.

After many surgeries and attempts to rehabilitate his left hand, Diamond and his doctors made the decision to amputate his hand just above the wrist.

“I remember I was crying the entire time saying please don’t take my hand, please don’t take my hand,” Diamond said.

He had to learn to function with a prosthetic replacement, which doesn’t allow for much movement. But, that’s what researchers at Southern Methodist University and the University of North Texas are trying to change.

“Today we have very sophisticated robotic arms,” explained Marc Christensen, chair of the electrical engineering department at SMU. “What we’re lacking is a good interface to control them.”

Dr. Gunter Gross at UNT, and Doctors Christensen and Volkan Otugen at SMU are working to create a system of fiber-optic wires and sensors that can replace the vast network of nerves inside a limb.

“It’s a link to send and receive information between the brain and the limb,” explained Dr. Otugen, chair of the mechanical engineering department at SMU.
