    Abstract: A system includes a pipe, a multiphase fluid, and a measurement unit. The multiphase fluid is disposed within the pipe. The measurement unit is connected to the pipe and includes a cylindrical structure, a first magnet, a second magnet, a first coil, and a second coil. The cylindrical structure is submersed in the multiphase fluid and has a first end and a second end. The first magnet is connected to the first end of the cylindrical structure, and the second magnet is connected to the second end of the cylindrical structure. The first coil is wound around the outer circumferential surface of the pipe in a location corresponding to a location of the first magnet disposed within the orifice. The second coil is wound around the outer circumferential surface of the pipe in a location corresponding to a location of the second magnet disposed within the orifice.

    Abstract: The invention relates to a system and methods for measuring and determining a characteristic of veneer with NMR spectroscopy in the serial production of veneer, wherein the measurement is taken as online measurement steps from veneer, the measurement steps comprising: creating a magnetic field with two magnets located on the opposite sides of veneer relative to the veneer and opposite to each other, and exposing hydrogen protons in water to the magnetic field for a time required by excitation of protons either by dimensioning the magnetic field in the travel direction of veneer to a sufficient range with respect to excitation of protons relative to the movement speed of the veneer or by moving the magnet and the magnetic field created by it in the travel direction of the veneer during the measurement, and determining veneer moisture distribution based on said amplitude and relaxation time of the backward signal.

    Abstract: The devices, systems, and methods can overcome the impact of scan protocols on experimental measurements to reconstruct the CEST equilibrium effect and can therefore improve the quantification of the underlying CEST contrast mechanism. The methods may include determining a spinlock relaxation rate for each RF offset for at least the first signal average so that the normalized spectrum for each RF offset and each slice first signal average corresponds to at least each transient state associated with each saturated slice readout normalized by at least each control state associated with each control slice readout based on the spinlock relaxation rate. The method may further include reconstructing CEST equilibrium effect for each RF offset using the respective spinlock relaxation rate for the RF offset. The method may include determining one or more quantitative information using the CEST equilibrium effect.

    CPC classification number: G01R33/448

    Abstract: A system to improve a product based on a relaxation response includes a memory configured to store relaxation response data of a sample. The relaxation response data includes time data and amplitude data. A processor is operatively coupled to the memory and configured to convert the relaxation response data to linear-amplitude versus log-time data. The processor also performs a least-squares fit of the converted relaxation response data to a heavy-tail function to determine one or more fit parameter values. The processor also updates a design for the sample based at least in part on the one or more fit parameter values.
