Seasonal Influences on the Impulse Characteristics of Grounding Systems for Tropical Countries

open access: yesEnergies, 2019
One of the most important parameters of the performance of grounding systems is the soil resistivity. As generally known, the soil resistivity changes seasonally, hence the performance of grounding systems, at DC and under high impulse conditions.

Basic observational characteristics of impulsive SXR brightenings [PDF]

open access: yesAdvances in Space Research, 2002
flares showing impulsive SXR brightenings have been investigated. The YohkohlSXT images have been used. The individual regions of the SXR response for each flare have been carefully localized. Some observational characteristics of them have been obtained. The results are presented in the form of histograms. For more comprehensive analysis HXR data from

Characteristics analysis of muzzle impulse noise based on wavelet energy spectrum

open access: yesJournal of Measurement Science and Instrumentation, 2015
Because muzzle impulse noise could cause damage to or have an influence on the operator,the effective protective measures should be taken.Therefore,correct analysis of impulse noise characteristics is very significant.Considering the shortcomings of fast

Research on Characteristics of Directional Impulse Sound Sources in a U-shape Connected Well [PDF]

open access: yesE3S Web of Conferences
The traditional U-shaped connected well connection technology mainly relies on the magnetic steering technology to guide the connection of the two wells, but the magnetic steering technology has the disadvantage of short detection distance.
