Low-Frequency Noise Suppression Method Based on Improved DnCNN in Desert Seismic Data
IEEE Geoscience and Remote Sensing Letters, 2019High-quality seismic data are the basis for stratigraphic imaging and interpretation, but the existence of random noise can greatly affect the quality of seismic data.

An axial flow fan includes blades mounted on a hub and extending radially outward to a shroud disposed around the hub. Pairs of stators are connected to the shroud at positions angularly spaced about the inner periphery of the shroud. Each pair of stators includes a trailing stator angularly spaced from a leading stator by a distance related to the ...

Much of the recent progress in our understanding of the world around us was achieved through the ability to detect very weak signals, for example from outer space, from nerve fibers, or from the ocean floor. To detect these weak signals, one requires very sensitive receivers, and hence the ability to amplify these signals without, at the same time ...

An improved water faucet having a valve body with control elements formed by two discs wherein the first disc is stationary and has water inlet openings and an outlet opening, connected on one side to the valve manifold. The other side is directed toward the second disc, which is movably arranged on the first disc.

Psychophysical measures using low-noise noise
The Journal of the Acoustical Society of AmericaThe term low-noise noise describes a non-Gaussian, random-phase signal with minimal fluctuations in the envelope. Also referred to as low-fluctuation noise and originally adopted for psychophysical investigation by Hartmann and Plumplin [J. Acoust. Soc. Am.

A blower for fluidized particulates has a housing with an inlet in one wall. The housing defines a chamber which also has an outlet. A rotatably mounted shaft projects into the interior of the chamber. Circumferentially spaced around and projecting laterally from the shaft are a plurality of blades which individually have a shape selected to ...

Ostensibly, one key component of any receiver chain is the low-noise amplifier (LNA) coming off the antennas. Since the signal at that point is comparatively weak, good gain and noise performance are necessary.
