ALERT and Los Alamos National Laboratory have received a $750,000 DARPA award for their partnership in Nuclear Magnetic Quadrupole Resonance research. Their proposal was submitted and accepted for the Methods for Explosive Detection at Standoff (MEDS) program. This project will be led by Prof. Carey Rappaport, the Principal Investigator from Northeastern University, and partner lead, Michelle Espy, from LANL.
ADSA09 – Call for Speakers February 4, 2013
ALERT is actively looking for speakers for the ADSA09 – Ninth Workshop for Algorithm Development for Security Applications: New Signatures for Explosive Detection for Aviation Security. This event will take place on May 7-8, 2013 at Northeastern University’s campus in Boston, MA.
Follow-on Funding Awarded to Dr. Conrad Jones January 16, 2013
Dr. Conrad Jones, a faculty member at Southern University, was awarded $50,000 of follow-on funding through the DHS Summer Research Team Program for MSIs. Dr. Jones was originally chosen to participate in the program during the summer of 2012 to work on ALERT research with Profs. Louisa Hope-Weeks and Brandon Weeks at Texas Tech University.
At the end of the summer, faculty participants are encouraged to apply for up to $50,000 in follow-on funding to continue the research collaboration at their home academic institutions during the following academic year.
Congratulations Dr. Jones!!!

ALERT Researcher Carey Rappaport discusses his work with Northeastern University November 28, 2012
Watch Professor Rappaport talk about his Homeland Security Related Research with Northeastern University:
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.
