Preventing Problems: Georgia Tech Helps to Develop System That Will Detect Insider Threats from Massive Data Sets

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.

Printed Protection: Low-cost Paper-based Wireless Sensor Could Help Detect Explosive Devices

Researchers at the Georgia Institute of Technology have developed a prototype wireless sensor capable of detecting trace amounts of a key ingredient found in many explosives.

The device, which employs carbon nanotubes and is printed on paper or paper-like material using standard inkjet technology, could be deployed in large numbers to alert authorities to the presence of explosives, such as improvised explosive devices (IEDs). (more…)

Choosing Microsoft Over the NFL

*Albert Rocker found himself at a crossroads of two big dreams: The Georgia Tech athlete had to choose between playing a final year of college football for a shot at the National Football League, or accepting a job offer from “the biggest software company ever created.”*

REDMOND, Wash. – It was the toughest decision of Albert Rocker’s life: should he pursue a career in the National Football League (NFL), or one at Microsoft?

At the Georgia Institute of Technology, Rocker was an outside linebacker for the Yellow Jackets football team with one year of eligibility remaining – one last football season to woo the NFL. Rocker played in a total of 38 games over his college career, including all 13 games of his junior season in 2010 – he was set to be a starter if he returned for his last year of eligibility.

Breaking Down Plastics: New Standard Specification May Facilitate Use of Additives that Trigger Biodegradation of Oil-Based Plastics in Landfills

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.

Better Weather: Water-vapor Profiling System Could Result in More Accurate, Less Costly Forecasting

Researchers at the Georgia Institute of Technology and Bennett Aerospace are leveraging light detection and ranging (lidar) technology to develop a ground-based system that will automatically measure water vapor in the atmosphere. Known as”WaV-ProTM,” for Water Vapor Profiler, the system aims to provide more frequent data collection that could dramatically improve weather forecasting.

Initial work on the project began in mid-2009, when Bennett Aerospace, in collaboration with the Georgia Tech Research Institute (GTRI), won a Phase I Small Business Innovation Research grant from the National Oceanic and Atmospheric Administration (NOAA) to develop design requirements for the system. Recently, the researchers won a Phase II grant to build and test critical components needed for a final operating prototype of WaV-Pro. (more…)

Cunning Machines: Researchers Give Robots the Capability for Deceptive Behavior

A robot deceives an enemy soldier by creating a false trail and hiding so that it will not be caught. While this sounds like a scene from one of the Terminator movies, it’s actually the scenario of an experiment conducted by researchers at the Georgia Institute of Technology as part of what is believed to be the first detailed examination of robot deception.
