Role of Static Modes in Quasinormal Modes Expansions: When and How to Take Them into Account?
Mathematics, 2022 The scattering of electromagnetic waves by a resonator is determined by the excitation of the eigenmodes of the system. In the case of open resonators made of absorbing materials, the system is non-Hermitian, and the eigenmodes are quasinormal modes ...

Reduction of the Induced Voltage in the Synchronous Generator Shaft Using Active AC / DC Converter
IEEE Access, 2020 Today, synchronous generators are broadly employed in the industry. The thyristor rectifier in the static excitation system of synchronous generators is responsible for supplying the DC voltage of the excitation winding.

Excitation transfer in disordered spin chains with long-range exchange interactions
SciPost Physics Core, 2023 We examine spin excitation or polarization transfer via spin chains with long-range exchange interactions in the presence of diagonal and off-diagonal disorder. To this end, we determine the mean localization length of the single-excitation eigenstates

IEEE Access, 2020 In the single-phase excitation mode of a four-phase 8/6 switched reluctance motor (SRM), the switch angle for each phase is usually high enough to improve the performance of the SRM, which can directly result in overlapping in excitation periods of each ...

Enhancement of a High Speed De-Excitation System for Brushless Synchronous Machines by large blocking voltage semiconductors [PDF]
, 2015 One of the main disadvantage of the synchronous machines with brushless excitation is that the field winding is not accessible for the de-excitation.

NON-RIGID KINEMATIC EXCITATION FOR MULTIPLY-SUPPORTED SYSTEM WITH HOMOGENEOUS DAMPING
International Journal for Computational Civil and Structural Engineering, 2018 This paper continues the discussion of linear equations of motion. The author considers non-rigid kinematic excitation for multiply-supported system leading to the deformations in quasi-static response. It turns out that in the equation of motion written
