ADSA24 Focuses on Collaboration in Aviation Security November 9, 2021

This October, ALERT hosted the ADSA24 workshop, the 24th installment of the Advanced Development for Security Applications (ADSA) workshop series, which has been assembling aviation security stakeholders from academia, government, and industry since its formation in 2009. The ADSA24 workshop focused on “Advancing Collaboration for Enhanced Security,” and in accordance with this theme, the workshop’s 172 attendees communed virtually on October 5-6 for expert-led presentations, engaging discussions on emerging technologies and industry standards, and networking in breakout rooms.

The ADSA workshop series is intended to address research opportunities that may enable the development of next-generation systems for the Transportation Security Administration (TSA) and Department of Homeland Security (DHS) Science & Technology (S&T) Directorate and to facilitate collaboration and innovation between researchers from universities, national labs, and the private sector.

“An effective collaboration occurs when there is a melding of complementary skills and points of view,” said Michael Silevitch, director of ALERT. “For example, a university analyst working closely with an industrial practitioner will often result in breakthroughs in the understanding of complex phenomena.”

Distinct topics that were addressed during the ADSA24 workshop included: establishing and maintaining collaborations, addressing obstacles to collaboration (building trust, navigating conflicts of interest and legal issues), stakeholder (TSA, DHS S&T, vendors, third parties, and airlines) perspectives on collaboration, and examples of successful and unsuccessful collaborations. Those who wish to learn more about the topics covered can view and download presentations from ADSA24 and previous ADSA workshops.

The ADSA workshop series places importance on the concept of technology foraging, or the process of identifying emerging technologies, products, and systems applicable to recognized capability gaps. ALERT intentionally seeks out experts in seemingly unrelated fields to present on their innovations and best practices, so that the ALERT community may obtain new perspectives and knowledge that could be applicable to aviation security. In keeping with this commitment to technology foraging, the ADSA24 workshop featured several presentations from experts in the medical imaging field, including talks from Jiang Hsieh, retired chief scientist at GE Healthcare, and Robert Nishikawa, professor and director of the Imaging Research Division in the Department of Radiology at the University of Pittsburgh.

“The frank and open nature of the presentations and ensuing discussions makes the ADSA experience concentrated and of high value,” said Carey Rappaport, deputy director of ALERT. “And with the understanding that the audience includes the widest variety of affiliation and discipline, ADSA stimulates a free flow of ideas, often outside the boundaries of typical workshops and conferences. Security experts learn from medical researchers, and manufacturers openly exchange ideas with policy makers.”

The next installment of the ADSA workshop series, ADSA25, will be held in Spring 2022 and ALERT plans to return to the in-person format at Northeastern University in Boston, MA. The dates, topics, and format of the workshop are forthcoming.

ALERT Explores Autonomous Security Systems in ADSA23 Workshop June 28, 2021

This spring, the ADSA23 workshop on “Autonomous Security Systems” was held virtually over the course of three sessions (May 4, 11, and 25). In response to COVID-19 protocols, the workshop continued to adhere to a virtual format, bringing together approximately 150 aviation security stakeholders from academia, government, and industry for compelling presentations and engaging conversations around emerging technologies, systems, and processes related to automation.

Members of the Transportation Security Administration (TSA) and Department of Homeland Security (DHS) Science & Technology (S&T) Directorate and other aviation security stakeholders facilitated insightful conversations on the workshop’s theme. Specific topics that were addressed and discussed by the ALERT community included: automation in passenger screening, detection of threats, and reduction of false alarms; stakeholder involvement in the design and operation of autonomous systems; automated testing and quality assurance; applications of interoperability; machine learning, and artificial intelligence; and best practices from other fields using autonomous systems. Those who wish to learn more about the topics covered can view and download presentations from ADSA23 and previous ADSA workshops.

The workshop was the 23rd installment of the Advanced Development for Security Applications (ADSA) series, which ALERT has convened since 2009. The series is intended to address research opportunities that may enable the development of next-generation systems and to facilitate collaboration and innovation between researchers from universities, national labs, and the private sector.

“Autonomous, automated, or automatic: essential characteristics of sophisticated systems that use advanced software to decide the best solutions. ADSA23 showed us the full spectrum of applications of computer-assisted decision making, from self-guided vehicles to threat declaration.” said Carey Rappaport, ALERT Deputy Director and ADSA23 speaker.

An important aspect of the ADSA Workshop series is the concept of technology foraging, or the process of identifying technologies, products, and systems applicable to recognized capability gaps. ALERT intentionally seeks out leaders in seemingly unrelated fields to present on their innovations and best practices, so that the ALERT community may obtain new perspectives and knowledge that could be applicable to aviation security. In keeping with this tradition, ADSA23 included presentations from Jay Stanley (American Civil Liberties Union), who addressed privacy and civil liberties considerations in relation to automated security systems, and experts in radiology, Robert Nishikawa (University of Pittsburgh) and Keith Dreyer (Massachusetts General Hospital), who both presented on issues related to artificial intelligence in the medical imaging field. ALERT would like to thank all the speakers and attendees who made ADSA23 a rich and collaborative experience.

ALERT is pleased to announce that the next workshop, ADSA24, will be held in-person on October 5-6. ALERT will also have a virtual option for those who cannot attend in person. The workshop will address “Advancing Partnerships for Enhanced Security” and include presentations and conversations on topics related to establishing and maintaining partnerships; recognizing successful and unsuccessful partnerships; stakeholder perspectives on partnerships; and important considerations around facilitating partnerships, such as biases, conflicts of interest, and legalities. Stakeholders in the ALERT community are encouraged to save the date for this workshop. More event details will be forthcoming.

ALERT Brings Together Stakeholders for Virtual Technology Showcase April 28, 2021

Like many events scheduled for 2020, the ALERT Technology Showcase had to be postponed due to the pandemic. As operations shifted online, ALERT leadership saw an opportunity to expand upon the ALERT Technology Showcase to better demonstrate the impact and transition of its research to the homeland security enterprise.

Leading up to the showcase, ALERT launched the SPARC (Seminars to Promote ALERT Research and Collaboration) webinar series—giving attendees a preview and deep-dive into some of the Center’s technology solutions—and shifted the ALERT Technology Showcase, which is typically held in person, to a fully virtual format. The newly imagined two-day event was successfully held on April 21 – 22 and brought together 137 stakeholders from across academia, industry, and government for presentations, demonstrations, and panel discussions that highlighted ALERT’s many research accomplishments, technologies, and collaborations.

“Shifting to the virtual format was a difficult challenge,” said Michael Silevitch, ALERT Director. “I want to commend the effort of the entire ALERT team to accomplish this important task. Their efforts went above and beyond the normal preparation for this type of event.”

The keynote address on the first day of the showcase was delivered by LaFonda Sutton-Burke, the Port Director for Customs and Border Patrol (CBP) at Los Angeles International Airport, who presented at ALERT’s inaugural CBP-ADEPT Workshop in 2018. On the second day, the keynote address was provided by Rebecca Medina, Director of the Office of University Programs at the Department of Homeland Security.

Over the course of the ALERT Technology Showcase, attendees observed nine technology demos, including:

  • Simulated Air Cargo Skids Task Order – Presented by Carl Crawford, Csuptwo LLC.
  • CLASP (Correlating Luggage and Specific Passengers) – Presented by Deanna Beirne, Northeastern University; David Castañón, Boston University; Octavia Camps, Northeastern University; Henry Medeiros, Marquette University; and Rich Radke, Rensselaer Polytechnic Institute.
  • Autonomous Raman System for the Analysis of Trace Residues on Surfaces – Presented by Eric Miller, Tufts University; and Romain Blanchard, Pendar Technologies.
  • UAV-Based Sensors for the Detection of Threats – Presented by Otto Gregory, University of Rhode Island.
  • Tool and Method for Simulating Explosives Particle Adhesion – Presented by Steve Beaudoin, Purdue University
  • Distributed, Low-Cost Multi-Sensor Detection, Imaging and Analysis Network – Presented by Scott Howard, University of Notre Dame
  • Astrophysics Multi-View CT – Presented by David Castañón, Boston University; and Brett Tally, Astrophysics Inc.
  • Zero Power Infrared Wireless Sensor Node in Collaboration with United Technology Corporation (UTC) – Presented by Matteo Rinaldi, Northeastern University; Zhenyun Qian, Northeastern University; and Sungho (Ryan) Kang, Northeastern University.
  • SCHMOO (Safe Control of Hazardous Materials or Others Onsite) – Presented by Jimmie Oxley, University of Rhode Island.

In addition to the technology demos, the event also included networking sessions in virtual breakout rooms where participants could approach presenters with follow-up questions and connect with one another, as well as two engaging panel discussions on the following topics:

  • ALERT Alumni Success Stories Moderated by Carey Rappaport, Northeastern University and featuring David Benirschke, University of Notre Dame; Limor Martin, SeeTrue AI; Alex Showalter-Bucher, DarkPumpkin AI (formerly with MIT Lincoln Lab); and Melissa Sweat, Defense Threat Reduction Agency (DTRA).
  • ALERT as an Emeritus Center – Moderated by Michael Silevitch, Northeastern University and featuring Jennifer Dy, Northeastern University; John Fortune, Department of Homeland Security; Matthew Merzbacher, Alameda County Community Food Bank; Fernando Quivira, Engineering Consultant; and Carey Rappaport, Northeastern University.

While in-person events are generally preferred, the virtual format of the ALERT Technology Showcase resulted in a turnout on par with that of ALERT’s previous showcase, but with greater flexibility and convenience for attendees who could log into the event from anywhere. ALERT plans to hold its next event, the ADSA23 Workshop on “Autonomous Security Systems” virtually as well—splitting the conference across three sessions (11:00 a.m. to 1:00 p.m. EDT) on May 4, 11, and 25.

From PhD Candidates to Professionals, ALERT Trio Continues to Collaborate February 22, 2021

Ziyan Wu, Srikrishna Karanam, and Meng Zheng understand the importance of collaboration. The trio of research scientists currently comprise a small, but effective, team at United Imaging Intelligence (Cambridge, MA); however, their professional journey together began as ALERT student researchers many years earlier.

Under the guidance of ALERT researcher and Rensselaer Polytechnic Institute (RPI) professor, Richard Radke, the three completed their doctoral programs at RPI—both Wu and Karanam completed their Ph.D. studies in Computer and Systems Engineering in 2014 and 2017, respectively, and Zheng completed her Ph.D. study in Electrical Engineering in 2020.

Furthering transformational research and next-generation technologies to address explosives-related threats is central to ALERT’s mission, as is demonstrating meaningful impact through its education program, which is focused on developing a highly skilled workforce for the homeland security enterprise. ALERT’s education program has introduced and guided hundreds of student researchers and career professionals into the workforces of the Department of Homeland Security (DHS) and its stakeholders.

During their academic careers, Wu, Karanam, and Zheng worked closely with Radke, contributing to ALERT’s Human Detection Re-Identification for Mass Transit Environments research project, as well as the task order: Video Analytic Surveillance Transition (VAST), which involved the installation of a testbed in the Cleveland Hopkins International Airport (CLE). Following these two successful projects, they worked on the initial phase of Correlation of Luggage and Specific Passengers (CLASP), which leverages a realistic mock airport security checkpoint built in ALERT’s Video Analytics Laboratory at the Kostas Research Institute (KRI) for Homeland Security.

“The work I did for ALERT was important to my development as a researcher, because it was connected to a challenging real-world problem with critical security outcomes. For example, if the system misses one person going the wrong way in a security checkpoint, then this presents a serious security risk to the entire airport. Because of this, I learned to pay extra attention to algorithm and system design to ensure that there were no loopholes, which helped me develop good habits as a researcher,” said Wu.

“Instead of focusing on the performance of one fancy algorithm and whether it was meeting our performance goal on a particular benchmark dataset, we had to take a much more comprehensive viewpoint and consider how it would perform and serve stakeholders in a real-world scenario.”

[YouTube Video: “Real-Time Airport Security Checkpoint Surveillance Using a Camera Network”]

In partnership with other ALERT researchers at Boston University and Northeastern University, and working closely with industry experts at Siemens, Radke’s research team was instrumental in developing the infrastructure for these testbeds—setting up camera networks and data recording devices, building software architecture, and developing algorithms to track passengers as they moved through the airport security checkpoint. According to Karanam, the real-world experience of collaborating with industry and Transportation Security Administration (TSA) professionals was beneficial to their careers.

“The typical Ph.D. student is concerned with publishing papers and graduating ASAP. In our situation, we were motivated by a real-world problem, and we had to work with real-world customers, both of which formed the basis of our unique PhD experiences. We learned how to map out customer needs and requirements, translate them to specific research problems, build algorithms and technical solutions to address the problems, and then manage expectations and communicate results properly with customers, who might not be experts in our technical area—in this case, computer vision,” said Karanam.

“When I was interviewing for jobs, I could sense that the people on the other side of the table were very surprised to hear that I had worked and communicated directly with customers as a Ph.D. student—it was very advantageous.”

After Wu completed his Ph.D. in 2014, he was hired at Siemens. Following in his footsteps, Karanam completed an internship under Wu, and was also hired at Siemens post-graduation. When the two moved on to United Imaging Institute, they brought Zheng on as an intern, who joined the team officially upon completing her Ph.D. in 2020.

Zheng attributes her problem-solving skills, which serve her well in her current professional role, to her time as an ALERT student researcher: “It provided me with the opportunity to apply the theoretical to real-world problems, such as checkpoint security, and that really helped me develop strong problem-solving techniques. I don’t think most Ph.D. candidates have that opportunity. This was the most valuable part of the experience for me.”

Radke looks back on the careers of his three students with pride:

“One of the best parts of being a professor is seeing your students grow and become independent researchers.  Ziyan, Srikrishna, and Meng were three of my best, and it has been deeply satisfying to watch them mentor each other and collaborate over the course of more than 10 years. Ziyan and I originally came up with the idea of simulating a security checkpoint on the RPI campus in 2010; Srikrishna helped design the CLASP testbed when it was just an empty room in 2016; Meng’s algorithms were some of the first we applied to the feeds from CLASP when it was up and running in 2017. Along the way, they published a ton of jointly authored papers, released several benchmark datasets and code libraries to help the community, and have gotten many computer vision algorithms developed in the lab to work robustly in real-world operational environments.”

The trio, which now spend their days developing computer vision algorithms for medical  applications, acknowledge it is a bit unusual to continue working so closely together post-graduation, but they were inspired by their Ph.D. advisor and his outlook on collegiality.

“Professor Radke actively encouraged graduating students to continue collaborating with current students—this motivated the three of us to continue collaborating and it is a large part of why we still work together today,” said Karanam

Virtual ADSA22: Improve Aviation Security by Reducing Operator Cognitive Load December 17, 2020

Unlike previous workshops in the Advanced Development for Security Applications (ADSA) series, this fall’s ADSA22 workshop, “Reducing Operator Cognitive Load in Aviation Security Equipment” was fully virtual and held over the course of four sessions (Nov. 17, Nov. 24, Dec. 1, and Dec. 8). While the change in format was due to the COVID-19 pandemic, it allowed for more robust attendance and engagement, especially from international attendees, as aviation security stakeholders from across academia, government, and industry were able to participate without having to travel.

These virtual sessions addressed the important topic of reducing operator cognitive load. Within aviation security, many security roles require continuous attention; workshop attendees gathered to discuss solutions to prevent vigilance decrement. The ADSA22 workshop addressed solutions to this problem, such as automating operator functions within aviation security, the adaptability of machine learning algorithms, implementing open architectures and third-party involvement, and emerging hardware and software technologies.

“As with most ADSA conferences held in the past, the virtual format held a plethora of technical information that was informative and engaging. This was all kicked-off by the RCA Assistant Administrator (Austin Gould) who, among other points of interest, made a strong note of awareness of COVID-19 and how TSA is actively adjusting technology endeavors to incorporate this vital component,” said Frank Cartwright, Capability Development & Integration (CDI) Branch Manager, Requirements & Architecture Division, TSA. “I don’t think the virtual format will completely replace the intangible benefits of a ‘live’ ADSA conference, but it truly pulled in all the main components which draw this community together.”

The workshop also focused on perspectives from the Transportation Security Administration (TSA) and Department of Homeland Security (DHS) Science & Technology (S&T) Directorate, and other aviation security stakeholders, and included thought-provoking talks from leaders outside aviation security—including professionals from the fields of sociology and medical imaging.

An important role of the ADSA Workshop series is technology foraging. ALERT intentionally looks for speakers in seemingly unrelated fields to present their technologies, because it is believed that can learn from these fields and technologies, and discover valuable applications for aviation security.

ALERT has hosted the ADSA Workshop series since 2009. Originally named the “Algorithm Development for Security Applications” Workshop series, the name was changed following ADSA10 in 2014 to reflect how the scope of the workshop series expanded beyond algorithm development. The ADSA Workshop series is intended to address research opportunities that may enable the development of next-generation systems and to facilitate collaboration and innovation between researchers from academia, national labs, and industry.

Dates for the spring workshop, ADSA23, have been set. ALERT stakeholders are encouraged to mark their calendars for May 4, 11, and 25—more information on the workshop and registration details will be forthcoming. ADSA23 will address the topic of Autonomous Systems for Aviation Security.

The final reports and presentations from ADSA22, and previous ADSA workshops are available to download here.

Additionally, ALERT will be hosting a series of half-hour seminars to allow deep-dives into specific topics related to aviation security. The seminars will begin in February 2021. Members of the ADSA community are encouraged to share specific topics of interest for these seminars with ALERT.

ALERT would like to thank all the presenters and attendees for making the ADSA22 workshop successful. In particular, ALERT would like to thank Frank Cartwright (Capability Development & Integration (CDI) Branch Manager, Requirements & Architecture Division, TSA) for coordinating TSA speakers, including an engaging keynote address from Austin Gould (Assistant Administrator for Requirements and Capabilities Analysis, TSA) and Diederik Stolk (Founding Partner, Goldsworthy, Stolk & Associates) for providing valuable insight on transforming the workshop into a virtual event.

ALERT Awarded Two New Homeland Security Task Orders December 17, 2020

Novel Technologies and Processes to Support Interdiction of Illicit Materials Task Order

ALERT received a task order from the U.S. Department of Homeland Security Science and Technology Directorate (DHS S&T) to support a two-year project known as “Novel Technologies and Processes to Support Interdiction of Illicit Materials,” with a specific focus on the mission needs of U.S. Customs and Border Protection (CBP). This task order builds on ALERT’s existing systems, methods, and algorithms for explosive threat detection, and it aims to improve DHS’s capabilities with respect to detection and interception of prohibited narcotics, agricultural products, currency, intellectual property, and other illegal goods entering through airports, land-border crossings, seaports, mail facilities, and cruise line terminals. ALERT will focus on facilitating the development of existing and emerging technologies and methodologies related to inspection of vehicles, people, mail, and containers in more efficient, effective, and cost-saving ways. This project will also assess the application of artificial intelligence and machine learning for DHS’s automated threat detection, operator assist algorithms, reconstruction algorithms, data-fusing algorithms, and cyber security efforts. ALERT brings specialized knowledge to this project with respect to projection and X-ray computed tomography at multiple energies, trace and vapor detection, Raman scatter spectroscopy, and more.

Enhanced Trace Explosives Detection, an Ambient Desorption Ionization Retrofitted Explosives Trace Detector Solution and a Continuous Automatic Non-Contact Sampler Based on Remote Heating Task Order

ALERT has received a task order from DHS S&T to support a one-year project known as, “Enhanced Trace Explosives Detection, an Ambient Desorption Ionization Retrofitted ETD Solution and a Continuous Automatic Non-Contact Sampler Based on Remote Heating.” This project’s tasks will be spearheaded by ALERT Thrust 1 Lead, Professor Jimmie Oxley (University of Rhode Island), Dr. Miriam Fico of ALERT’s industrial partner Smiths Detection, and ALERT collaborator, Avi Cagan of Eneregan, LLC.

ETDs are regularly used by DHS as a screening tool, but current ETDs have limitations. One component of this project will focus on the development of an Ambient Desorption Ionization module and its integration with currently deployed ETDs to selectively identify current and emerging explosives threats. This ADI retrofit solution greatly enhances ETD capabilities. Further, the work will include the investigation of novel non-contact sampling technologies to expand the ability to perform sampling at airport checkpoints, while minimizing the chances of viral cross-contamination and improving collection efficiency. Lastly, the project will perform a scenarios-based feasibility study on explosive vapor detection.

ALERT Researchers Work with U.S Army on Energetic Materials October 30, 2020

ALERT researcher Steve Beaudoin, professor of chemical engineering and director of Purdue University’s Energetic Research Center, and past ALERT researcher Jeffrey Rhoads, professor of mechanical engineering and director of the Ray W. Herrick Laboratories at Purdue’s College of Engineering, are engaged in a new three-year collaboration with the U.S Army to advance technology concerning explosives, propellants, and pyrotechnics (a.k.a. energetic materials). The project, formally known as Advancing Army Modernization Priorities through Collaborative Energetic Materials Research, focuses on priorities such as increasing effectiveness of weapons and increasing safety and sustainability.

For Purdue News, Rhoads, who is the leader of this major award, reported that there are currently eighteen research projects and groups conducting energetics research as part of this project, focusing on topics such as “gaining a better understanding of how shockwaves interact with the microstructure and defects in energetic materials; improving the performance of materials used in the aggressive service conditions such as gun launch and hypersonic flight; developing inkjet-printed conductive energetic materials; [and] developing new manufacturing techniques to encapsulate metal or composite materials with embedded sensors to develop health-monitoring smart armor.”

Professor Beaudoin currently leads ALERT research Thrust 2, “Trace and Vapor Sensors,” described in Northeastern University’s ALERT annual report as concentrating on understanding “the fundamental problems of trace and vapor detection of explosives and aiming to enable development of sensing and sampling systems capable of detecting ultra-low amounts of explosives which are both selective (i.e., able to reduce the number of false positives and false negatives) and adaptable (i.e., can accommodate new explosives as they become threats).”

Professor Rhoads also previously worked on research within ALERT’s Thrust 2, focusing on research and development of portable, integrated microscale sensors for explosives detection.
