Center for Adaptive Security Research and Applications

We’re excited to introduce a refreshed user experience in this latest version of CASRA’s flagship product, the X-Ray Tutor. With a completely redesigned interface, it is now presented in contemporary design. Navigating and accessing your tools is now more intuitive and efficient than ever. Alongside the new look, this release includes updates for improved performance, stability, and new features to enhance your workflow. Dive in to explore all the enhancements designed with you in mind! For more information click here. 

Members of CASRA recently published a study in the International Journal of Industrial Ergonomics on remote cabin baggage screening (RCBS) versus traditional screening at the lane, i.e. local cabin baggage screening (LCBS). The study used linear mixed models for analyzing threat image projection (TIP) data from 1706 screeners collected over two years (669’168 TIP events). The results showed better detection of prohibited articles (higher hit rate) and longer processing times in RCBS than in LCBS. In both settings, we found a decrease in the hit rate with increasing time on task, and this decrease was stronger when the task load was high. Interestingly, the effects of work setting, time on task, and task load were relatively small compared with the interindividual differences in performance across screeners. The published paper is available here.

Since 2012, we have been publishing newsletters in which we summarize CASRA’s research results and refer to trends in the security sector.
The first article describes the Airport Checkpoint Effectiveness Simulation (ACES), a software we developed for comparing different airport security checkpoints regarding security effectiveness. The second article presents insights into the upcoming relaunch of CASRA’s X-Ray Tutor (XRT), training and testing platform for X-ray screening. This includes a new user interface.
