Webb26 juli 2024 · Acoustic emission (AE) testing is traditionally carried out on non-operating objects. Such requirement is associated both with the Kaiser effect, leading to the necessity for exceeding the test load above the working one and with a high level of noise during object operation. However, AE testing could be performed under operating … Webb25 jan. 2024 · We propose a heat-reconfigurable metasurface composed of the silicon-based gold grating. The asymmetric Fano-like line shape is formed due to the mutual coupling of the local surface plasmon (LSP) in the gap between the two layers of Au gratings and the surface propagating plasmon (SPP) on the surface of the Au gratings. …
WebbRain attenuation along earth space path is calculated from rain rates using ITU-R model [9] for different frequencies from 30 to 60 kHz at different path lengths. Plotting of rain attenuation at 30 GHz against rain rate along terrestrial path and earth space path of 5 km length is shown in the Figure.5. From Figure.5 we see that earth Webb11 feb. 2010 · 2.11.7 System Interference and Channel Guard Bands 39. 2.11.8 ...

The European climatological high-resolution gauge-adjusted radar precipitation dataset, EURADCLIM, addresses the need for an accurate (sub)daily precipitation product covering 78 % of Europe at a high spatial resolution. A climatological dataset of 1 and 24 h precipitation accumulations on a 2 km grid is derived for the period 2013 through 2024.
