Performance-Optimizing Secure GBAS Over LDACS [PDF]
2021 Integrated Communications Navigation and Surveillance Conference (ICNS), 2021 VHF Data Broadcast (VDB) currently used by GBAS has been identified as a potential source of cyber-security concerns. The use of an alternative datalink providing the bandwidth for more capable security protocols has therefore been proposed and demonstrated on the basis of the L-band Digital Aeronautical Communication System (LDACS). However, the first

Examining the Use of Game-Based Assessments for Hiring Autistic Job Seekers
Journal of Intelligence, 2021 Although people with autism are protected under the Americans with Disabilities Act of 1990, there is little theoretical or practical effort to determine whether traditional pre-employment assessments unfairly impact autistic job seekers. Due to the lack

The Mathieu group M-12 and its pseudogroup extension M-13 [PDF]
, 2006 We study a construction of the Mathieu group M-12 using a game reminiscent of Loyd's "15-puzzle." The elements of M-12 are realized as permutations on 12 of the 13 points of the finite projective plane of order 3.
