Year 4 Program Review Highlights ALERT Student Involvement January 27, 2017

The ALERT Year 4 Program Review was held on January 11th & 12th at Northeastern University in Boston, Massachusetts. The purpose of this review was to evaluate the ALERT research portfolio at both the theme and project levels, as well as the Center’s education program, transition efforts, and industrial partnerships. Several graduate students from ALERT’s academic partner institutions presented at this year’s review on behalf of the research projects in which they are currently involved.

University of Rhode Island PhD candidates, Austin Brown and Kevin Colizza presented on ALERT research related to the characterization and safe elimination of explosives materials, which they conducted under the guidance of Dr. Jimmie Oxley. Research in explosives characterization and elimination is especially important to those in the Homeland Security Enterprise tasked with the detection, identification, and destruction of homemade explosives (HMEs), such as bomb squads, and other first-responders.

Purdue University M.S. candidate, Nick Cummock presented on ALERT research led by Dr. Steven Son and related to small-scale characterization of homemade explosives (HMEs). The specific compositions of HMEs are nearly limitless, so making accurate assessments of threats from these materials is challenging. This research project seeks to develop a small-scale experimental approach that will result in quicker and more cost-effective characterization of HMEs, leading to greater accuracy in modeling and prediction of explosives related threats.

University of Puerto Rico Mayagüez M.S. candidate, Amanda Figueroa presented on her research project led by Dr. Samuel Hernandez. This research project deals with the use of infrared spectroscopy (IR) in standoff mode and coupled to laser sources operating in the mid-infrared (MIR) to develop confirming orthogonal chemical sensors for detecting explosives residues on clothing, travel bags, personal bags, laptop bags/cases, skin, and other substrates.

Xiao Wang, another Purdue University student and PhD candidate, presented on ALERT research conducted under the guidance of Dr. Charles Bouman and Dr. Ken Sauer related to advanced baggage screening and automatic target recognition (ATR), which is achieved via algorithms and devices primed to recognize objects based on data obtained from sensors. This research project seeks to improve the detection of potential threats in scanned baggage and reduce the false alarm rate without compromising safety at airport security checkpoints, resulting in a reduction of security costs and an overall safer and smoother experience for passengers.

Northeastern University PhD candidate, Mengran Gou presented on ALERT research led by Dr. Octavia Camps and Dr. Mario Sznaier and related to video-based methods to identify and track potential threats in heavily crowded public spaces. Video-based methods have an enormous potential for providing advance warning of terrorist activities and threats. In addition, they can assist and substantially enhance localized, complementary sensors that are more restricted in range, such as radar, infrared, and chemical detectors.

In addition to the outstanding ALERT student presentations that took place at the Year 4 Program Review, the Center introduced four new research projects taking place at Boston University, Duke University, Purdue University, and the University of Notre Dame.

ALERT REUs Present Summer Research August 29, 2016

This summer, ALERT hosted three undergraduate students at Northeastern University to participate in a 10-week Research Experience for Undergraduates program. The ALERT REU program at NEU is partnered with other REU programs in the university’s College of Engineering, and builds a cohort of motivated students who attend professional development meetings and program activities, including presentations on Research Ethics, Lab Safety, PowerPoint Presentation Skills and Scientific Storytelling. At the end of the summer, each REU gives a final presentation of their research project. The presentation addresses the project’s overall mission and endeavors, the REU’s specific contributions to the project, as well as what knowledge and skills they gained through the process. This year’s students worked on projects related to ALERT’s Bulk Sensors & Sensor Systems research.

REU Anthony Bisulco (’18) is a third year NU student who worked with Professor Jose Martinez-Lorenzo on ALERT’s Rapid Security Threat Detection via MIMO (Multiple Input, Multiple Output) Millimeter Wave Imaging project.

In his words, “The main purpose of my REU project is to improve the overall passenger experience during the airport security screening process. Currently, this process is plaqued with many downfalls such as slow throughput, frequent false alarms and significant passenger divestment and recollection. The working goal of the project I am working on is to improve this process by creating ‘On the Move Screening’ where passengers walk at a normal pace through what appears to be a tunnel without the need to divest any clothing or personal items.”

Anthony’s project worked to increase the image quality of a 3D imaging millimeter wave radar (“Tunnel System”) with the goal of improving the system’s threat detection capability. “One part of this radar is various transmitters/receivers which illuminate/receiver the target (Human Torso) at various angles. As a result of adding transmitters/receivers the image quality is increased. Rather than adding multiple transmitters or receivers, my project added microwave switches to the system, which is the equivalent of adding more transmitters and receivers for imaging. Overall, I mainly designed the system for controlling these switches and developed some algorithms for optimizing the best imaging positions.”

Spencer Pozder (‘19) and Justin Xia (‘19) worked with Professor Carey Rappaport on Feasibility Investigations in Multistatic Imaging Techniques for their Research Experience. Currently, active millimeter wave radar is used for imaging objects concealed on the human body at airport security checkpoints. The current monostatic configurations are unable to accurately image objects at certain angles, give lower resolution, cost more, trigger more false alarms and have longer execution times. ALERT is interested in a multistatic configuration in an “On the Move” scanning system, capable of receiving image information from multiple angles in parallel, possibly increasing resolution and accuracy of the images produced.

The team developed a product using hardware from ALERT Industrial Partners, Rapiscan and Analog Devices, creating a functional system and imaging algorithm capable of reconstructing images. They also redesigned and relocated transmitter and receiver boards to accommodate the optimized system configuration and designed mechanical structure for holding transmitters and receivers. The “On the Move” system is currently being prototyped and patented.

In addition to this program, ALERT partner universities, including the University of Puerto Rico at Mayagüez and Notre Dame, also hosted summer REU participants in their labs.

The REU program is hosted and sponsored by the Awareness and Localization of Explosives-Related Threats (ALERT) Department of Homeland Security Center of Excellence, and the Bernard M. Gordon Center for Subsurface Sensing and Imaging Systems (Gordon-CenSSIS), a Graduated National Science Foundation Engineering Research Center.

ALERT Demos Tech at Centers of Excellence Technology Showcase June 28, 2016

June 28, 2016

ALERT brought its advances in explosives detection research to the 2016 Centers of Excellence Technology Showcase in Washington D.C. last month. The event featured “Chat with an Expert” sessions, informational tables for each center, information on training opportunities, and live demonstrations. The Department of Homeland Security, Science and Technology Directorate, Office of University Programs hosted the showcase at the Ronald Reagan Building in Washington D.C. for over 250 government agencies and first responders.

Professor Jimmie Oxley represented ALERT in one of the “Chat with an Expert” sessions, which allowed participants to have 10 minutes of one-on-one time with each expert to discuss specific technologies, center research, or opportunities for partnership. Professor Oxley also led ALERT’s live demo of the day: “Trace Explosives Aids for Scent (TEAS).” Her research team developed a method of polymer encapsulation that is used to create safe trace explosives sources. Their research results show that Polycarbonate microspheres containing only a low percentage of Triacetone Triperoxide (TATP) last for years, yet produce pure TATP vapor when heated at the designated program rate. Although they contain small amounts of actual explosives material, these TEAS are called pseudo-explosives because they have no potential to explode, thus providing users with safe access to stored hazardous explosives at trace levels for the purpose of training K-9s and calibrating instrumentation.

Currently, 29 groups have tested prototypes of ALERT’s training aids, including NY MTA Police, MA State Police, Toronto Police, and industry collaborators such as K-9 Search On Site, and FLIR Systems, Inc.

The Live Demo

Officer William Qualls and his K-9 partner, Nate, demonstrated how they use TEAS in the field by having attendees hide one of the activated TEAS somewhere in the Showcase space and then having Nate work to find it. Travis Kisner, Director of Engineering from Detectachem, presented the microsphere heater Detectachem developed for use with ALERT’s TEAS.

ALERT’s Research and Networking with End Users

ALERT team members, Emel Bulat (Industry Liaison) and Deanna Beirne (Director of Computer Services), presented ALERT technologies and center capabilities to the broad showcase audience. Center tools like VAST, PIMS and MVCTC were highlighted by the team and were of great interest to the participants. Videos and Fact Sheets for each tool were also on display.

The event resulted in dozens of connections for the center and a better understanding of what challenges end users like U.S. Customs and Border Protection and the Transportation Security Administration are facing. ALERT is looking forward to furthering linkages with end users and providing solutions to those challenges in our areas of expertise.
