The article brings forth the results of analysis of the existing practice of coding diagnoses, discusses the drawbacks of the existing model leading, in the long run, to impossibility of literate building of a monitoring system for morbidity rate and

Explicit three-dimensional (3D) point source and multi-Gaussian beam models are obtained for the Rayleigh waves generated by a surface wave angle beam transducer using an angular plane wave spectrum approach. Simulations show that the multi-Gaussian

A complete ultrasonic measurement model is obtained for contact testing, where all the electrical, electromechanical, and acoustic/elastic elements are explicitly described. Reciprocity principles are used to model those acoustic/elastic elements tha

The expansion coefficients of a multi-Gaussian ultrasonic beam model are obtained by a new approach that applies Prony´s method in a K -space domain. This method allows the fitting of the Gaussian beam directly at the face of the transducer with ver

A new transducer beam model, called a multi-Gaussian array beam model, is developed to simulate the wave fields radiated by ultrasonic phased-array transducers. This new model overcomes the restrictions on using ordinary multi-Gaussian beam models de

A multi-Gaussian beam model is used to simulate an immersion transducer radiating into an anisotropic solid through a curved fluid–solid interface. It is shown that the characteristics of the beam as it propagates in the solid are controlled by the

A model is developed for the propagation and reflection/transmission of Gaussian beams in multilayered media where the layer materials can be general anisotropic, homogeneous elastic solids and the layer interfaces can be curved surfaces. It is shown
