On the stability of an in-line formation of hydrodynamically interacting flapping plates

Autor: Nitsche, Monika, Oza, Anand U., Siegel, Michael

The motion of several plates in an inviscid and incompressible fluid is studied numerically using a vortex sheet model. Two to four plates are initially placed in-line, separated by a specified distance, and actuated in the vertical direction with a

ISSF: The Intelligent Security Service Framework for Cloud-Native Operation

Autor: Yan, Yikuan, Huang, Keman, Siegel, Michael

The growing system complexity from microservice architectures and the bilateral enhancement of artificial intelligence (AI) for both attackers and defenders presents increasing security challenges for cloud-native operations. In particular, cloud-nat

HUBBLE SPACE TELESCOPE PROPER MOTIONS OF INDIVIDUAL STARS IN STELLAR STREAMS: ORPHAN, SAGITTARIUS, LETHE, AND THE NEW 'PARALLEL STREAM'

Autor: Sohn, Sangmo Tony, van der Marel, Roeland P., Kallivayalil, Nitya, Majewski, Steven R., Besla, Gurtina, Carlin, Jeffrey L., Law, David R., Siegel, Michael H., Anderson, Jay

We present a multi-epoch Hubble Space Telescope (HST) study of stellar proper motions (PMs) for four fields along the Orphan Stream. We determine absolute PMs of several individual stars per target field using established techniques that utilize dist
