January 29, 2018

Muhammad Usman Ghani, a Ph.D. candidate in Electrical and Computer Engineering at Boston University, is now in his second year working on ALERT research with Professor Clem Karl. His project, “Advanced Multispectral Computed Tomography (CT) Algorithms” (Project R4-C.1), involves developing learning based algorithms to improve the quality of imaging reconstructions for CT, and applies many areas of his interest, including, machine learning, computer vision, and statistical signal processing. When asked how he initially became interested in ALERT research, he describes an early interest in image processing and machine learning, and states, “The focus of ALERT research is on the cross-roads of inverse problems in imaging and image analysis. Additionally, it is an applied kind of research, which has always driven me. When Professor Karl introduced me to the ALERT research, I instantly became interested.”

A driving force behind his work is his desire to see real world technology applications address the large scale and ever present security challenges faced today. Usman’s goal is to solve various image acquisition and analysis problems, specifically in security scenarios, and is currently working with Professor Karl to draw on big data to develop new machine learning based methods to improve image reconstruction. Outside of research, Usman loves to travel and immerse himself in new cultures, learning about the world’s religions and eating amazing food. When asked where he sees himself in 5-10 years, he is sure research will be part of his career, but has yet to decide if he will stay in academia or work in industry. Either way, his passion for learning and exploring is sure to lead to a rich and exciting future!

“ADSA in Three Words” (Video) January 29, 2018

What began as a relatively small workshop (approximately 30 attendees) on the campus of Northeastern University (Boston, MA) in 2009, has evolved into an interactive biannual conference series with over 150 participants regularly. Viewed by participants as a “forum which brings together many different communities with a common goal of solving security challenges,” (ADSA17 participant quote), the ADSA (Advanced Development for Security Applications) Workshop series intends to facilitate collaboration and innovation between these communities.

At the last ADSA workshop (ADSA17 Workshop), ALERT asked several participants to sum up the biannual event in only three words. See what government, industry, and research participants had to say in “ADSA in Three Words.”

ADSA17: Providing Solutions for Aviation Security November 27, 2017

November 27, 2017

The Seventeenth Advanced Development for Security Applications (ADSA17) Workshop convened on October 17-18, 2017 at Northeastern University in Boston, MA. Participants from academia, industry, and government gathered to engage in dialogue related to the theme of the ADSA17 Workshop: “Systems Engineering of Aviation Security Systems.” Specific topics discussed included requirement specifications for systems and subsystems; the acquisition and use of metadata; assessment, management, and use of risk; and layered security.

The ADSA17 Workshop featured more than thirty presentations from subject matter experts and leaders from industry and government over the course of two days. Presentation topics included emerging technologies, such as sensors and algorithms; aviation cargo inspection; stakeholder perspectives; behavior detection; and deep learning.

ADSA17 participants shared their views on the value of the ADSA Workshop series. ALERT Thrust R4 (Video Analytics and Signature Analysis) Leader, Professor David Castañón (Boston University) stated, “For me, as an academic researcher, the most valuable asset is getting a sense of what industry wants to address and what the government feels that its primary problems are. That helps us match what we can do with what they perceive as the big problems. I think if you ask the question for different communities that are represented here, you would get very different perspectives on the value. Some are here for the networking aspect, some are here to get educated on what other people think are the real problems that they could address and business opportunities, and others are looking for technologies. As an academician, I’m asking myself: What is the next big problem we ought to be focusing on?

Dr. Mark Witinkski, Vice President of the Chemical Analysis & Security Group at Pendar Technologies, shared his viewpoint as an industry participant, “I go to a lot of conferences, and this doesn’t feel like one. The quality of the research and the quality of what is being presented is every bit as good as you would see at the top conferences, but it has that workshop feel where you can interact during the presentations and really discuss things after the talks and during lunch. There is ample opportunity and emphasis placed on that. We’ve formed a few really important collaborations during those times and that probably wouldn’t have happened at a traditional conference.”

The DHS Center of Excellence (COE) for Awareness and Localization of Explosives-Related Threats (ALERT) has convened the ADSA Workshop series since 2009. Originally named the “Algorithm Development for Security Applications” workshop series, the name changed in 2014 following the ADSA10 Workshop to reflect how the scope of the workshop series has expanded beyond algorithms. The purpose of the ADSA Workshop series is 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.

Rappaport Delivers IEEE Distinguished Lectures in Australia and New Zealand November 27, 2017

November 27, 2017

ALERT Deputy Director and Northeastern University Electrical and Computer Engineering Distinguished Professor, Carey Rappaport, delivered three IEEE Distinguished Lectures in Australia and New Zealand earlier this month. The IEEE Antennas and Propagation Society (AP-S) selected Professor Rappaport as a Distinguished Lecturer for 2017-2019. The IEEE AP-S Distinguished Lecturer Program sends experts, the Distinguished Lecturers, to visit active IEEE AP-S Chapters around the world and give talks on topics of interest and importance to the Antennas and Propagation community. Professor Rappaport gave the following talks during his recent visit to Australia and New Zealand:

  • “Electromagnetic Sensing and Treatment of Living Things: Using Microwaves to Detect and Treat Disease in Humans and Trees” (Melbourne, Australia)
  • “A High Gain Toroidal Reflector Antenna for Multistatic 3D Whole Body Millimeter-Wave Imaging” (Queenstown, New Zealand)
  • “Multifocal Bootlace Lens Design Concepts” (Sydney, Australia)

On the value of being an IEEE Distinguished Lecturer, Professor Rappaport states, “The IEEE Distinguished Lecturer Program supports one of the fundamental precepts of academic research: extending the dissemination of knowledge and cutting-edge discovery to as wide an audience as possible. In presenting my team’s engineering work around the world, I have been able to help engineers extend their scientific awareness beyond their traditional themes, and occasionally outside their comfort zones. Although the travel commitment is time-consuming, it has been a great opportunity to meet people and exchange technical ideas.” Professor Rappaport will be delivering another IEEE Distinguished Lecture in January 2018 to the IEEE AP-S chapter in Orlando, Florida.

Professor Rappaport has been a Northeastern University faculty member since 1987, becoming a full professor in Electrical and Computer Engineering in July 2000, and receiving an appointment as a College of Engineering Distinguished Professor in 2011. Professor Rappaport has written over 400 technical journal articles and conference papers on various topics, including electromagnetic wave propagation and scattering computation, microwave antenna design, and bioelectromagnetics. He has also received two reflector antenna patents, two biomedical device patents, and four subsurface sensing device patents.

ALERT Researcher Awards & Accomplishments September 27, 2017

September 26, 2017

Professor Bouman Nominated for ACM Gordon Bell Prize

Professor Charles Bouman of Purdue University has been nominated for an ACM (Association for Computing Machinery) Gordon Bell Prize. Professor Bouman co-leads research on the ALERT project, “Toward Advanced Baggage Screening: Reconstruction and Automatic Target Recognition (ATR)” (Project R4-B.1), with the overarching goal of finding the best mapping method from X-ray data to a decision on the relative safety of individual bags in security settings, such as airport checkpoints. Professor Bouman and his research team study the reconstruction problem with the end goal of detection, while also designing algorithms for image analysis that can best exploit the improved image quality in iterative methods. Their aim is to reduce the false alarm rate without sensitivity loss in detection. They hope to eventually reduce security costs to the transportation industry.

The Gordon Bell Prize is awarded each year to recognize outstanding achievement in high-performance computing. The purpose of the award is to track the progress over time of parallel computing, with particular emphasis on rewarding innovation in applying high-performance computing to applications in science, engineering, and large-scale data analytics. Prizes may be awarded for peak performance or special achievements in scalability and time-to-solution on important science and engineering problems.

Professor Jose Martinez-Lorenzo Awarded $546K DOE Grant

Professor Jose Martinez-Lorenzo of Northeastern University was awarded a $546K grant from the Department of Energy (DOE) for “Fusing Thermoacoustic, Electromagnetic and Acoustic/Seismic Wave Fields for Subsurface Characterization and Imaging of Flow Transport.” According to the DOE, “The overarching goal of this research program is to gain knowledge on the theory and experimental validation of a new unified sensing and imaging methodology for coupling Electromagnetic (EM), Acoustic/Seismic (AC/S), and novel Thermoacoustic (TA) physical fields, which will be applicable to multi-physics and multi-scale material characterization and underground imaging of fluid flow in porous media.” This research will help Professor Martinez-Lorenzo build upon his work with ALERT, specifically Project R3-B.1 and Project R3-B.2.

Professor Otto Gregory Awarded Patent for Gas Sensor System

Professor Otto Gregory of the University of Rhode Island was awarded a patent for “Systems and Methods for the Detection of Compounds” on September 12, 2017. Triacetone-Triperoxide (TATP) is an explosive commonly used in improvised explosive devices (IEDs) and is very difficult to detect using conventional explosives detection techniques, because most of these techniques were developed for nitrogen-based chemistries, not peroxide-based chemistries. In addition, TATP readily sublimes at room temperature, meaning that it can only be found in relatively high concentrations in the vapor phase compared to other commonly found explosives used in IEDs. Professor Gregory’s invention provides a gas sensor system for detection of a compound that decomposes upon exposure to a metal oxide catalyst, and incorporates the exposure of the compound to a microheater, which allows accurate detection to occur at smaller concentrations. For more information on Professor Gregory’s research with ALERT, see Project R2-B.1.
