This paper introduces a brand-new phase definition called the segmental phase for multi-input multi-output linear time-invariant systems. The underpinning of the definition lies in the matrix segmental phase which, as its name implies, is graphically based on the smallest circular segment covering the matrix normalized numerical range in the unit disk. The matrix segmental phase has the crucial product eigen-phase bound, which makes itself stand out from several existing phase notions in the literature. The proposed bound paves the way for stability analysis of a cyclic feedback system consisting of multiple subsystems. A cyclic small phase theorem is then established as our main result, which requires the loop system phase to lie between -π and π. The proposed theorem complements the celebrated small gain theorem.
In post-disaster scenarios, field robots and unmanned aerial vehicles (UAVs) are effective tools to provide an ondemand response and guarantee the safety of humans. Sensors, field robots, and the devices equipped by U...

Image distortion caused by the angular misalignment of quadrupole magnets in high-energy electron radiography has been studied *** propose that the distortion originates from the coupling of the electron motions in the transverse directions,based on a theoretical analysis and the transfer-matrix *** relative angular rotation between the second and third magnetic quadrupoles was identified as the main contributor to image *** was verified by both a beam-dynamics simulation and *** strategies to mitigate this image distortion are also explored,including magnets online tuning,higher beam energy and larger magnification *** study provides criteria for designing experiments and paves the way for achieving higher image precision.
