ALERT hosts TSA Administrator, John Pistole and Boston Air Security Officials at NEU June 18, 2013
On June 12th, 2013, the ALERT Center at Northeastern University hosted a visit by the Transportation Security Administration (TSA) Administrator, John Pistole, along with acting Boston Field Office Supervisory Air Marshal, David Brown, Boston Logan International Airport Federal Security Director, George Naccara and Kenneth Fletcher, Senior Advisor to the Deputy Administrator at TSA.
The visit was led by the Deputy Director of ALERT, Professor Carey M. Rappaport and included a tour of the Advanced Imaging Technology (AIT) lab where a group of 20 undergraduate and graduate students participated in demonstrations of ALERT research projects, including Multistatic Millimeter-Wave AIT scanning and Real-Time High-Value 3D External Surface Imaging using the X-Box Kinect sensor.
Professor Rappaport also presented his Standoff Detection Experiment, which uses a powerful millimeter-wave radar unit to detect threats from a distance, such as concealed body-worn explosives.
The tour continued in the Video Analytics Lab run by ALERT Professors Octavia Camps and Mario Sznaier. Using cameras and monitors, Professors Camps and Sznaier, along with their students, staged the lab to look like an airport exit lane, and asked Administrator Pistole and his associates to participate in a demonstration of the lab’s Video Analytic Surveillance Transition (VAST)software. The demonstration showed how their software flags “counter-flow” activity, by detecting people who walk “in” through an “exit” lane, thereby alerting security personnel if a person attempted to bypass a TSA checkpoint. Similar software is used for identifying left objects, which was demonstrated by the team when another program flagged a backpack which was left on the ground by a student walking through a crowd.
The visit was an excellent opportunity to present both ALERT research, and other security research that is being done at Northeastern University to Administrator Pistole and his group.

ALERT Co-Director Provides Insight on Marathon Bombing Devices April 20, 2013
ALERT Co-Director Jimmie Oxley speaks with Rhode Island News Team 10 about the type of explosive devices used in the Boston Marathon Bombings.
Pressure cooker bombs, like the ones reportedly used in the explosions near the finish line at the Boston Marathon, are a common and simple way to make an explosive device, according to a University of Rhode Island chemistry professor.
“It only takes a small amount of black powder to ignite a powerful blast,” said Jimmie Oxley, who also is a member of the U.S. Department of Homeland Security Center for Excellence for Explosives, Detection, Mitigation and Response.
She said if you put it inside a common kitchen pressure cooker, you’ll have a weapon. The steel container will make fragments which are what do the most damage.
“If you feel the sharpness of those edges, if that hits you, you can see why it takes off an arm. If it was a pressure cooker, it would create frag,” Oxley said.
Oxley said of all terrorist weapons, a homemade bomb is the most accessible…Read More

ALERT welcomes United States Secretary of Homeland Security, Janet Napolitano November 19, 2012
Awareness and Localization of Explosives-Related Threats was pleased to host U.S. Secretary of Homeland Security, Janet Napolitano on Monday, November 12th following her keynote address at Northeastern University’s Veteran’s Day Ceremony.
To kick off the visit, ALERT’s Director, Professor Michael B. Silevitch, provided Secretary Napolitano with an overview of the ALERT Center of Excellence. Prof. Silevitch then introduced undergraduate and graduate students involved with ALERT research and gave a summary of the demonstrations in video analytics and advanced imaging technologies that were prepared for her briefing. Michael described Napolitano’s visit as a significant opportunity for ALERT and its homeland security research, saying,
“It was very important to get validation from Secretary Napolitano about the relevance of our research and its transition to the field in the areas of video tracking of threats and passenger screening. This acknowledgement inspires us.”
Professor Octavia Camps led the first demonstration featuring ALERT’s Engage to Excel (E2E) Video Analytic Surveillance Transition project, VAST. VAST is a program developed in partnership with Siemens and the Cleveland Transportation Security Administration. The live demonstration exhibited the video analytic counter-flow program developed by Dr. Camps and her team and its ability to automatically detect when a person is proceeding the wrong way in an identified traffic pattern (for example, trying to enter through an exit). The resulting detections enable quick identification of an incident and minimize the impact on TSA resources. This project is currently installed within the Cleveland Hopkins International Airport.
Following the video analytics demonstration, Professor Carey Rappaport showed Secretary Napolitano the capabilities of the ALERT Advanced Imaging Technologies (AIT) laboratory. This laboratory fuses together various scanning tools to create next-generation security scanning systems. Professor Rappaport, Assistant Professor Jose Martinez and graduate student Spiros Mantzavinos demonstrated the operation and data acquisition capabilities of ALERT’s advanced portal-based millimeter-wave imaging radar. During the demo, the system scanned a mannequin wrapped in a skin simulant with various representative objects attached for detection. These types of AIT systems can be used to detect illicit items that passengers may be attempting to carry on their person.
“As a DHS-supported researcher, I found Secretary Napolitano’s visit very satisfying,” Prof. Rappaport commented. “She was of course quite knowledgeable about the science and technology we are pursuing, but she seemed keenly interested in how we were improving the state of the art. She was completely supportive and she motivated the students with her passion to keeping Americans safe.”
Spiros Mantzavinos, currently a Northeastern University Doctoral Candidate in Electrical and Computer Engineering and Gordon Engineering Leadership Fellow, had the opportunity to meet Secretary Napolitano. Mantzavinos said, “It was an honor to host Secretary Napolitano for a visit to our ALERT whole-body imaging lab. Receiving attention and recognition from such a prominent figure in the national security arena assures the relevance of the advances we are making.”
Handheld IED Detection Device with Firestorm Emergency Services November 8, 2012
ALERT research out of Missouri University of Science and Technology, led by Prof. Daryl Beetner, is currently working to develop methods to indirectly detect and locate explosives by identifying the electromagnetic emissions from these electronic initiators. This approach has the advantage that a device can potentially be detected from tens or even hundreds of meters away in a very short period of time using relatively small, inexpensive, low-power sensors.
Hidden explosives can be extraordinarily difficult to locate. While the most obvious approach is to look for the explosive compound, techniques which look for these compounds often only work from short distances, can only be used over a very limited area, or are very slow to generate a detection. An alternative is to instead look for the electronic trigger that is used to initiate the explosive. Electronics used in triggers like timers, wireless receivers, motion detectors, and microcontrollers, emit electromagnetic energy (i.e. radio waves) when they are turned on. These radio waves can potentially be detected from long distances in a short period of time using relatively small, inexpensive, low-power sensors.
In the last year, Beetner and his team have developed techniques to locate (not just detect) radio receivers using a stimulated emissions approach. Detection of electronics has an advantage over many other explosives detection techniques in that it can potentially be done relatively quickly from relatively long range and can be done with relatively inexpensive equipment. It gives the bomb technician one more point of information with which to make a decision about the presence of explosives and how to deal with the explosives once found. As Beetner explains, “We’ve developed methods to accurately detect and locate the most common types of radio receivers. We’ve shown that these techniques are fast and work well at long distances, even in very noisy urban environments”. While detection of suspect electronics does not necessarily indicate the presence of an explosive device, this information can be combined with other information relatively easily to confirm or add information about a threat. The information is unique from other explosive sensors so it is well primed for sensor fusion.
ALERT has teamed up with Firestorm Emergency Services to develop a commercial product around algorithms developed by Beetner and his group. Firestorm manufactures a small, inexpensive, hand-held device for detecting and locating the electromagnetic signatures from aircraft emergency beacons and from radio location beacons worn by Alzheimer’s patients, so they already have hardware under development that is ideal for the team’s approach. The fundamental detection methods developed here are also being extended with Firestorm to develop systems for locating vehicles at remote border crossings.
