Use of Subharmonics of Base Frequencies in the CSRMT Method with Loop Sources
J, 2023 In the controlled source radiomagnetotelluric (CSRMT) sounding method, a horizontal magnetic dipole, HMD (vertical loop) or a horizontal electric dipole, and HED (grounded line) are used as sources.

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

Subharmonics in a class of planar periodic predator-prey models [PDF]
, 2021 This contribution studies the existence of positive subharmonics ofarbitrary order in the planar periodic Volterra predator-prey model. When themodel isnon-degenerate, in the sense that the birth rate of the prey intersects thesupport of the death rate ...

Subharmonics and Auditory Nerve Tuning Curves in Gerbil [PDF]
, 2010 In the literature, an auditory nerve tuning curve obtained from single unit recording typically has a tail and a tip. Responses beyond the tip in the well supra-CF frequency region had never been documented.
