Based on our research, the Self Affine Feature Transform (SAFT) was introduced as it extracts quantities which hold information of the edges in the investigated image region. This paper gives details on algorithms which extract various geometric information from the SAFT matrix. As different image types should be analysed differently, a classification procedure must be performed first. The main...

Synthetic Aperture Focusing Technique imaging has became a popular tool in the field of non-destructive testing in the past years. The acquisition procedure consists in collecting the data after activating elements one by one. The reconstructed object is then computed by adding the contribution of each channel, selecting the proper time delay values. It is the principle of the well-known delay ...

A new model for correlating self-diffusion coefficients is proposed here. It based on the entropy scaling concept and makes it possible to quantitatively estimate in any fluid state (subcritical gas liquid as well supercritical states). general relationship between a dimensionless form of coefficient function Tv-residual proposed. This involves thermodynamic properties that were straightforward...

The synthetic aperture focusing technique (SAFT) is a well-established method for improving the resolution of an ultrasonic image. A major shortcoming is the inherent assumption that the pulse reflected from a flaw has a spectral content that is independent of the flaw's location relative to the transducer. In this project, we address the issue by using SAFT combined with Wiener filtering and a...

Synthetically focused imaging has been used for some time in the NDE community. The techniques have primarily been directed towards imaging using bulk waves. There has recently been use of SAFT (Synthetic Aperture Focusing Technique) using guided waves in plates. Here, we review three different synthetically focused imaging algorithms for a linear array aperture: CSM (Common Source Method), SAF...

Hydrogen (H2) has emerged as a viable solution for energy storage of renewable sources, supplying off-seasonal demand. contamination due to undesired mixing with other fluids during operations is significant problem. Water regular occurrence; therefore, an accurate prediction H2-water thermodynamics crucial the design efficient and water removal processes. In thermodynamic modeling, Peng–Robins...
