Finite Element Solutions for Magnetic Field Problems in Terfenol-D Transducers

Finite Element Analysis of Stationary Magnetic Field

A finite element model to simulate magnetic field distribution and laboratory studies in wet low-intensity magnetic separator

Low-intensity magnetic separators are widely used in the research works and the industry. Advancement in the magnetic separation techniques has led to an expansion in the application of this method in different fields such as enrichment of magnetic mineral, wastewater treatment, and medicine transfer in the human body. In the mineral processing industry, the main application of wet magnetic sep...

State-Identification Problems for Finite-State Transducers

A well-established theory exists for testing finite-state machines, in particular Moore and Mealy machines. A fundamental class of problems handled by this theory is state identification: we are given a machine with known state space and transition relation but unknown initial state, and we are asked to find experiments which permit to identify the initial or final state of the machine, called ...

Magnetic Field Measurements Based on Terfenol Coated Photonic Crystal Fibers

A magnetic field sensor based on the integration of a high birefringence photonic crystal fiber and a composite material made of Terfenol particles and an epoxy resin is proposed. An in-fiber modal interferometer is assembled by evenly exciting both eigenemodes of the HiBi fiber. Changes in the cavity length as well as the effective refractive index are induced by exposing the sensor head to ma...
