Evaluation of Two Tension Sensors for Cable‐Driven Parallel Manipulators

open access: yesJournal of Field Robotics, Volume 42, Issue 4, Page 1191-1208, June 2025.
ABSTRACT Cable‐driven parallel manipulators (CDPMs) constitute a class of parallel robots in which the frame is connected to the end‐effector through a set of cables. The weight reduction achieved by replacing rigid links with cables, along with their exceptionally large workspace, makes CDPMs suitable for applications such as positioning devices ...

Assessment of Practical Satellite Quantum Key Distribution Architectures for Current and Near‐Future Missions

open access: yesInternational Journal of Satellite Communications and Networking, Volume 43, Issue 3, Page 164-192, May/June 2025.
ABSTRACT Quantum key distribution (QKD) allows the generation of cryptographic keys beyond the computational hardness paradigm and is befitting for secure data transmission requiring long‐term security. The communication distance of fiber‐based QKD, however, is limited to a few hundred kilometers due to the exponential scaling of signal attenuation ...
