In the frequency (f) regime of interest for microwave engineers, there exist three (one longitudinal ... with little decay of the amplitude under the ambient temperature and pressure. At audio ...

Seismological research is directly related to the incubation, occurrence, and evolution of earthquakes. Scientists seek to ...

There have been rockets launching from Vandenberg for decades, so why are the Falcon 9 launches of such concern? "Because of ...

A sound wave is a vibration that travels through a solid, liquid or gas such as the air or water. A loud sound has a large amplitude, a high pitched sound has a high frequency. Musicians and ...

Discover how subtle changes in vocal tone and patterns can reveal cellular aging processes before visible signs appear, and ...

And demodulation is practically the exact opposite, where the message signal is extracted from the carrier wave and used. In this article, we are going to learn about modulation and more about ...

Abstract: The propagation properties of longitudinal dust acoustic waves (LDAWs) have been investigated in a strongly coupled dusty plasma containing negatively charged dust fluid, and nonthermal ...

Pulse pressure and pulse wave velocity, markers of arterial stiffness, have been associated with stroke, dementia, and lowered levels of cognitive function. Here we examine longitudinal relations of ...

H s Height of significant wave (metres). This is the average height of the highest one third of the waves in the record. H max Maximum height of the waves (metres) in the record. T z Average wave ...

Arterial stiffness and earlier wave reflections can increase afterload and impair cardiovascular function. Most prior studies have been performed in patients with preserved left ventricular function.
