Visual Servoing of Quadrotors for Perching by Hanging from Cylindrical Objects

Visual Servoing of Quadrotors for Perching by Hanging from Cylindrical Objects Abstract: This letter addresses vision-based localization and servoing for quadrotors to enable autonomous perching by hanging from cylindrical structures using only a monocular camera. We focus on the problems of relative pose estimation, control, and trajectory planning for maneuvering a robot relative to cylinders […]


Authenticated Key Exchange Protocols for Parallel Network File Systems

Authenticated Key Exchange Protocols for Parallel Network File Systems Abstract: We study the problem of key establishment for secure many-to-many communications. The problem is inspired by the proliferation of large-scale distributed file systems supporting parallel access to multiple storage devices. Our work focuses on the current Internet standard for such file systems, i.e., parallel Network […]
