When a soldier in good mental health becomes homicidal or a government employee abuses access privileges to share classified information, we often wonder why no one saw it coming. When looking through the evidence after the fact, a trail often exists that, had it been noticed, could have possibly provided enough time to intervene and prevent an incident.
With support from the Defense Advanced Research Projects Agency (DARPA) and the Army Research Office, researchers at the Georgia Institute of Technology are collaborating with scientists from four other organizations to develop new approaches for identifying these “insider threats” before an incident occurs. The two-year, $9 million project will create a suite of algorithms that can detect multiple types of insider threats by analyzing massive amounts of data — including email, text messages and file transfers — for unusual activity.

Despite efforts to encourage the recycling of plastic water bottles, milk jugs and similar containers, a majority of the plastic packaging produced each year in the United States ends up in landfills, where it can take thousands of years to degrade. To address that problem with traditional polyethylene, polypropylene, Styrofoam and PET products, researchers at the Georgia Institute of Technology are working with the Plastics Environmental Council (PEC) to expand the use of chemical additives that cause such items to biodegrade in landfills.
Added during production of the plastic packaging, the compounds encourage anaerobic landfill bacteria and fungi to break down the plastic materials and convert them to biogas methane, carbon dioxide and biogenic carbon – also known as humus. These additives – simple organic substances that build on the known structures of materials that induce polymer biodegradation – don’t affect the performance of the plastics, introduce heavy metals or other toxic chemicals, or prevent the plastics from being recycled in current channels.

A ground-breaking innovation, birthed in a sudden flash of insight, is the stuff of legend. Air conditioning, Kevlar, the DNA-replicating process known as PCR (polymerase chain reaction) — each was the product of a Eureka! moment. The list may soon be longer by one, thanks to a wandering mind and a napkin.
When Jud Ready attended an academic conference on materials science in Boston in 2003, he didn’t plan on coming home with the idea for a three-dimensional solar cell, but that’s what happened. (more…)
With research and development assistance from the Georgia Tech Research Institute (GTRI) and seed funding from the Georgia Research Alliance (GRA), an Atlanta-based company is developing what it hopes will be the next-generation instrument for optimizing eyesight for the hundreds of millions of people who wear glasses or contacts – or who are candidates for corrective surgery.
To be used by optometrists and ophthalmologists, the instrument – known as the VisionOptimizer – is intended to provide more accurate vision measurements, along with a more patient-friendly and engaging vision test. The company believes its system will facilitate the custom-manufacturing of spectacles and contact lenses that provide better eyesight and improved wearing comfort compared to conventional prescriptions.

Researchers at the Georgia Tech Research Institute (GTRI) have developed a novel iPhone application that may enable persons with Parkinson’s disease and certain other neurological conditions to use the ubiquitous devices to collect data on hand and arm tremors and relay the results to medical personnel.
The researchers believe the application could replace subjective tests now used to assess the severity of tremors, while potentially allowing more frequent patient monitoring without costly visits to medical facilities. (more…)
With more than 20,000 abandoned and active gas and oil wells in the Gulf of Mexico, oil leaks and spills pose a continuous threat to the region’s ecosystem. Monitoring the health of the ecosystems helps ensure the sustainability of natural resources, and helps protect human health and the environment.
Researchers at the Georgia Tech Research Institute (GTRI) are developing an advanced-warning system to detect the presence of oil in saltwater. The sensor-based system offers the potential for remotely, autonomously and continuously monitoring bodies of water for oil. (more…)
Researchers at the Georgia Tech Research Institute (GTRI) are poised to show the U.S. Army an advanced approach to enabling autonomous collaboration among dissimilar robotic vehicles. (more…)
The Georgia Tech Research Institute (GTRI) has created a new Cyber Technology and Information Security Laboratory (CTISL) to apply GTRI’s broad expertise and systems engineering experience in cyber-related research to a broad range of information security issues. (more…)
