Dual-Mode Brushless Wound Rotor Synchronous Machine for High Starting Torque
This paper proposes a dual-mode brushless wound rotor synchronous machine (DBL-WRSM) for high starting torque. The proposed DBL-WRSM consists of two modes: induction and brushless (BL)-synchronous modes.

Nonlinear Interaction of Low-frequency Alfvén Waves and Ions
The interaction between Alfvén waves and particles is a critical phenomenon in space and laboratory plasmas, and it has been observed that low-frequency Alfvén waves can accelerate and heat ions through subharmonic resonant interactions.

A Simulation for Detecting Nonlinear Echoes from Microbubbles Packets
This work presents a simulation of the response of packets of microbubbles in an ultrasonic pulse-echo scan line. Rayleigh-Plesset equation has been used to predict the echo from numerically obtained radial dynamics of microbubbles. Varying the number of

Anharmonic classical time crystals: A coresonance pattern formation mechanism
Driven many-body systems have been shown to exhibit discrete time crystal phases characterized by broken discrete time-translational symmetry. This has been achieved generally through a subharmonic response, in which the system undergoes one oscillation ...

Unified subharmonic oscillation conditions for peak or average current mode control [PDF]
SummaryThis paper is an extension of the author's recent research in which only buck converters were analyzed. Similar analysis can be equally applied to other types of converters. In this paper, a unified model is proposed for buck, boost, and buck–boost converters under peak or average current mode control to predict the occurrence of subharmonic ...

Higgs time crystal in a high-T_{c} superconductor
We propose to induce a time-crystalline state in a high-T_{c} superconductor, by optically driving a sum resonance of the Higgs mode and a Josephson plasma mode. The generic cubic process that couples these fundamental excitations converts driving of the
