Small-scale MHs have an obvious influence on the spectral indices of the magnetic fluctuations by their high-frequency components ... Martian magnetosheath may be correlated with the upper ionosphere.

We start discussing the measurements of mechanical parameters and variations of geochemical fluids detected before earthquakes; then we review thermal and atmospheric oscillations; finally, ...

Surrey Space Centre, School of Computer Science and Electronic Engineering. Professor Ryden is currently Interim Director of the Surrey Space Centre, a research unit within the School of Computer ...

While the majority of Amateur Radio operators choose only a few of the HF bands, below 30 MHz ... The altitude of the VUSHF antennas is crucial for tropospheric propagation. The focus of this club is ...

First, the numerical model of the long-distance propagation of LEMP in the Earth-ionosphere waveguide (EIWG) is constructed by using the auxiliary differential equation finite difference time domain ...

Abstract: This paper presents the design and implementation of Software-Defined Floating-Point (SDF) number formats for high-speed implementation of the Belief Propagation (BP) algorithm. SDF formats ...

The Earth’s ionosphere is the ionized upper part of the atmosphere, and it’s also the most dynamic as it swells and ebbs depending on whether it’s exposed to the Sun or not. It’s the ...

If you are familiar with radio propagation you’ll know that radio ... As you move through the lower end of the VHF into the HF (Short Wave) portion of the spectrum and below, the radio signal ...
