Abstract: Accurately estimating propagation factor over multiple frequencies within the marine atmospheric boundary layer is crucial for the effective deployment of radar technologies. Traditional ...

For many plant lovers, propagation can feel like a daunting task. There is nothing more disappointing than waiting for a propagated stem to root, only to have it fail and have to be thrown out.

On 25 October 2013, the Sun emitted two significant solar flares. The first solar flare, classified X1.7, peaked at 08:01 UT. The second one, X2.1, peaked at 15:03 UT and was accompanied by solar ...

A DSTG engineer attaches a radio frequency cable to the engineering model of the Buccaneer Main Mission nanosatellite. (Commonwealth of Australia) The Australian Department of Defence (DoD) has ...

Variations in the underwater sound speed significantly influence sound propagation in the ocean, thereby impacting both underwater navigation systems and a substantial portion of marine organisms ...

ABSTRACT: The São Francisco River basin is 2368 km long, with an average annual flow of 2846 m3/s and a drainage area of 639,219 km2. About 54% of this area lies in Brazil’s semi-arid northeast, with ...

The dynamic response characteristics of high and steep slopes under the action of earthquakes and blasting was focused on, especially the frequency distribution and propagation laws, which are crucial ...

Abstract: The Multi-Carrier Modulation (MCM) technique in the Near Vertical Incidence Skywave (NVIS) propagation mode poses a challenge due to the ionosphere’s dynamic behavior. The selection of the ...
