The S-transform kernel is derived from the kernel of the Fourier transform through the
introduction of a scalable, translating window. The width of the window is a function of …

Ultrasound shear wave elastography (SWE) is a technique used to measure mechanical
properties to evaluate healthy and pathological soft tissues. SWE typically employs an …

Laser Doppler flowmetry signals give information about many physiological activities of the
cardiovascular system. The activities manifest themselves in rhythmic cycles. In order to …

The Stockwell transform (ST), recently developed for geophysics, combines features of the
Fourier, Gabor and wavelet transforms; it reveals frequency variation over time or space …

Hydraulic conductivity (K) and specific storage (S s) are closely related to porosity, the
compressibility of aquifer skeleton, connectivity of pores, sorting of the grains, and many …

Sustainable aquifer management in coastal cities is becoming critically important due to the
challenges of climate variability amidst population growth. Study of the aquifer heterogeneity …

This study evaluated the spatial variability of hydraulic conductivity (K) along the Han River
watershed in the Jianghan Plain (China) by using different geostatistical methods. The K …

Recent applied literature introduces the Stockwell transform (S-transform) as a new
approach to time-frequency analysis. It is the purpose of this letter to encourage the …

In this article, we extend the Stockwell transform to the space of all square integrable
quaternion-valued functions on the real line, using the convolution of quaternion-valued …
