Simulation of localized electron density enhancement caused by high-pressure H2O gas release in ionosphere

open access: yesAIP Advances, 2023
Based on the continuity and momentum equations, a self-consistent simulation model is developed for describing the localized electron density enhancement caused by high-pressure H2O gas release in the ionosphere.

Feasibility and Error Analysis of Using Fiber Optic Temperature Measurement Device to Evaluate the Electromagnetic Safety of Hot Bridge Wire EEDs

open access: yesSensors, 2022
Most studies assessing the safety of hot bridge wire EEDs employ temperature sensors that directly use the measurements of the temperature measurement device without analyzing the accuracy of the temperature measurement.

Study on the best calculation scheme of equivalent evaporation duct feature

open access: yesThe Journal of Engineering, 2019
In view of the lack of applicability of the existing equivalent evaporation duct feature calculation scheme in China's sea area and the requirement of the evaporation duct model test, this study used the actual sounding data in China's coastal areas and ...

Fostering Data Sharing in Multidisciplinary Research Communities: A Case Study in the Geospatial Domain

open access: yesData Science Journal, 2019
The sharing of research data allows for information reuse and knowledge advancement but its realization is often a challenge and seldom successful in practice. We propose a workflow for the design of a User Support System (USS) aimed at tutoring research

The Enlightened Game of Life [PDF]

open access: yes, 2010
We investigate a special class of cellular automata (CA) evolving in a environment filled by an electromagnetic wave. The rules of the Conway's Game of Life are modified to account for the ability to retrieve life-sustenance from the field energy.

Research on the test method of substituting bulk current injection for electromagnetic radiation in the coupling channel of parallel double lines

open access: yesAIP Advances, 2021
Radiation effect test cannot be performed in large-scale space simulations of a strong field electromagnetic environment, and existing BCI (bulk current injection) technology employed for nonlinear system tests is subjected to its limitation. Given this,

The Earth's electromagnetic environment [PDF]

open access: yesGeophysical Research Letters, 2011
It is found that the energy density of electromagnetic fields at the surface of the Earth follow a scaling law that extends over 16 orders of magnitude from 10-9 Hz to 107 Hz. The temporal variability of the field can be described with an 1/f2, or Brownian, noise power spectrum which reflects the superposition of numerous transient source processes. To

Prediction method of multi-frequency non-intermodulation electromagnetic radiation blocking effect of BeiDou navigation receiver

open access: yesAIP Advances, 2022
In the test of the electromagnetic radiation blocking effect of the navigation receiver, it is found that the sensitivity of the navigation receiver to single frequency continuous waves and sinusoidal amplitude modulation waves will change with the ...

A Burned Area Mapping Algorithm for Sentinel-2 Data Based on Approximate Reasoning and Region Growing

open access: yesRemote Sensing, 2021
Sentinel-2 (S2) multi-spectral instrument (MSI) images are used in an automated approach built on fuzzy set theory and a region growing (RG) algorithm to identify areas affected by fires in Mediterranean regions. S2 spectral bands and their post- and pre-
