Abstract: Acoustic impedance (AI) inversion method based on the assumption of spatially invariant seismic wavelets has been widely applied in reservoir prediction. In reality, seismic wavelets are ...

In recent years, semi-supervised methods have significantly improved the efficiency and precision of impedance inversion. However, methods based on convolutional neural networks (CNNs) often struggle ...

Choosing the best acoustic guitar for your personal needs is a tough one. With so many options on offer these days it’s not surprising that many find themselves faced with option paralysis when ...

But after a couple of years of work, xMEMS has arrived at the next generation — ultrasound through a solid-state speaker. This tiny, 1mm-thin speaker is called Cypress, and after listening to it ...

The device delivers ultrasound energy to the patient’s pancreas and generates localized heat of up to 100 degrees Celsius that destroys cancer cells in the organ. Other types of ultrasound waves ...

Here, we introduce an in-operando acoustic technique based on acoustic impedance spectroscopy (AIS) which probes the mechanical changes that occur in the LIB during operation. Using thin, inexpensive ...

Part of today’s research in ultrasound is to gain more information on the acoustic properties of the object imaged. These advanced imaging and reconstruction procedures require more complicated ...
