Distributed point source method for eddy current modelling
Nondestructive Testing and Evaluation, 2023Distributed point source method (DPSM) has been gradually applied to the field of nondestructive testing (NDT). As a semi-analytical modelling technique, DPSM is extremely powerful and straightforward for solving various engineering problems, such as ...

Sound field reconstruction using compressed modal equivalent point source method
The Journal of the Acoustical Society of America, 2017The accuracy, resolution, and economic cost of near-field acoustic holography (NAH) are highly dependent on the number of spatial sampling points. Generally, higher accuracy and resolution require more spatial sampling points, which may increase the workload of measurement or the hardware cost.

Source splitting via the point source method
Inverse Problems, 2010We introduce a new algorithm for source identification and field splitting based on the point source method (Potthast 1998 A point-source method for inverse acoustic and electromagnetic obstacle scattering problems IMA J. Appl. Math. 61 119–40, Potthast R 1996 A fast new method to solve inverse scattering problems Inverse Problems 12 731–42).

Ultrasonic field modeling in anisotropic materials by distributed point source method
Ultrasonics, 2017DPSM (distributed point source method) is a modeling technique which is based on the concept of Green's function. First, a collection of source and target points are distributed over the solution domain based on the problem description and solution requirements.

A Point-Source Method for Sampling Soil Atmospheres
Transactions of the ASAE, 1980ABSTRACT A point-source soil atmospheric sampler was designed and field tested. Equilibration periods of 1 h after placement were enough to achieve representative in situ samples from an agricultural silt loam soil. Vectorial variability of C02 in the horizontal direction was occa-sionally significant, whereas variability of C02 was con-sistently ...
