It is noted that the WDM networks place new requirements on the EDFAs that include maintaining flatness over many links and recovering from sudden drops or adds of channels.
When the structure with thin walls formed by paper is loaded, the shape of deformation is different from that of the metal, wall swells and does not maintain its flatness.
To maintain membrane flatness during filtration, the membrane is supported by a porous plastic disk (Porex Corporation, Fairburn, GA).
However, in the tonal signal model (1), a noise term is also present, hence the solution to the LP estimation problem will be a compromise of attenuating the tonal components, while increasing (or maintaining) the flatness of the noise spectrum.
The objectives maintain superb image flatness throughout the field of view and long working distances supported by a focus lock to prevent objectives and specimens from damage.
Here, in order to maintain the spectral flatness of A norm k), the LF spectrum is uniformly divided into 14 sub-bands in the frequency scale and each LF sub-band contains N subband = 16 frequency bins.
They tend to curl up some as they dry, so it's important to flatten them gently between two plates to maintain a uniform flatness.
The multiple membrane layers are deployed to a planar structure with the deployment of the frame and maintain the required surface flatness through the tensioning system between the membrane and frame.
The coronagraph implementation specifies that each segment maintains an overall flatness better than 10 nm RMS, irrespective of segment angle.
The catalyst surface coverage determined by Cu stripping voltammetry showed that the surface of the nanosheet catalysts was completely covered by Pt after 2 SLRR cycles and maintained the original atomic flatness of the Ru nanosheet core.
Maintain, maintain, maintain.
