Permanent Magnet Hybrid Core Inductors for High Saturation Capability
IEEE Open Journal of Power Electronics, 2023 Inductor designs with large dc current relative to ac ripple are often constrained by saturation, which limits their size, loss, and current-carrying capability.

Implication of an Integrated Approach to the Determination of Water Saturation in a Carbonate Gas Reservoir Located in the Persian Gulf [PDF]
Journal of Petroleum Science and Technology, 2017 Water saturation determination is one of the most important tasks in reservoir studies to predict oil and gas in place needed to be calculated with more accuracy. The estimation of this important reservoir parameter is commonly determined by various well
