2. Point-source/point-receiver methods

2001
Publisher Summary This chapter explains a suite of techniques that elicit information on the elastic properties of solids using point-like excitation and detection of ultrasound. These point-source/point-receiver (PS/PR) techniques have shown great promise in several materials' inspection and characterization applications.

A method for predicting odour frequencies from a point source

Atmospheric Environment (1967), 1972
Abstract It is demonstrated that a fluctuating plume dispersion model can be used to give realistic estimates of odour frequencies around a point source, when the odour threshold of the chimney gases is determined by sensory methods ( Lindvall , 1970). The theoretical calculations are compared with observational results from a field experiment at and

Multiple point source location via infrared array processing methods

[1990] Proceedings. The Twenty-Second Southeastern Symposium on System Theory, 2002
The detection and location of multiple targets in a noisy environment are considered. High-resolution direction-finding techniques have proved to be effective in radar and sonar multiple-target-location applications. In these problem domains, the data being modeled can be represented as a linear combination of fundamental signals whose behavior is ...

Ultrasonic field modeling in anisotropic materials by distributed point source method

Ultrasonics, 2017
DPSM (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.
