Induction Motor Supplied with Voltage Containing Symmetrical Subharmonics and Interharmonics
Energies, 2022 Sinusoidal voltage fluctuations can be considered a specific result of the occurrence of voltage subharmonics and interharmonics, which are components of low frequency or not being an integer multiple of the frequency of the fundamental voltage harmonic.

Tidal River Flood Risk Highest During Intermediate Rather Than Peak River Discharge
AGU AdvancesTidal rivers are defined as the tide‐influenced, salinity‐free inland reaches of estuaries. Understanding the occurrence of peak water levels (PWLs) is critical for flood risk management, yet the timing and magnitude of PWLs in tidal rivers have been ...

Subharmonics with Minimal Periods for Convex Discrete Hamiltonian Systems [PDF]
Abstract and Applied Analysis, 2013 We consider the subharmonics with minimal periods for convex discrete Hamiltonian systems. By using variational methods and dual functional, we obtain that the system has a -periodic solution for each positive integer , and solution of system has minimal

Journal of Differential Equations, 1986 We consider a piecewise linear second order ordinary differential equation which is topologically equivalent to the sine-Gordon equation. The system is subjected to a time harmonic disturbance and the behavior of the periodic solutions is examined. It is shown that subharmonic motions with period n times that of the disturbance appear via saddle- node ...
