An Overview on Concepts Drift Learning
(Ieee-inst Electrical Electronics Engineers Inc, 2019-01-01)
Concept drift techniques aim at learning patterns from data streams that may change over time. Although such behavior is not usually expected in controlled environments, real-world scenarios can face changes in the data, ...
Drift Velocity Estimation of Ionospheric Bubbles Using GNSS Observations
(2021-08-01)
Equatorial plasma bubble (EPB) irregularities are large-scale plasma depleted structures that exist in the equatorial and low-latitude ionosphere. Thus, particularly in these regions, much attention must be given to the ...
Vertical ionization drifts in the lower equatorial ionosphere and the meridional current systems
(American Geophysical Union, 1976-03-01)
Recent radar observations near the magnetic equator show that the electron vertical drift velocity below 200 km is upward during the day and downward at night, in agreement with measurements made at higher heights. The ...
Measurements of electron drift velocity in isobutane using the pulsed townsend technique
(American Institute of Physics, 2014)
Comparison of ionosonde and incoherent scatter drift measurements at the magnetic equator
(American Geophysical Union, 2006-01-10)
It has been proposed that ionosondes can be used to measure vectorial nighttime ionospheric drifts at F region altitudes. These measurements have been validated at mid and high magnetic latitudes on campaign basis. Here ...
A simulation study on the impact of altitudinal dependent vertical plasma drift on the equatorial ionosphere in the evening
(American Geophysical Union, 2015-02-28)
We carry out a simulation study on the impact of altitudinal dependent plasma drift on the equatorial ionosphere in the evening, under geomagnetically quiet conditions. Our study used the vertical plasma drift velocity ...
A dedicated setup for the measurement of the electron transport parameters in gases at large electric fields
(ELSEVIER SCIENCE BV, 2010)
Electron transport parameters are important in several areas ranging from particle detectors to plasma-assisted processing reactors. Nevertheless, especially at high fields strengths and for complex gases, relatively few ...
A computer code to calculate then fast induced signals by electron swarms in gases
(American Institute of Physics, 2014)
Theoretical relationship between maximum value of the post-sunset drift velocity and peak-to-valley ratio of anomaly TEC
(American Geophysical Union, 2004-02-11)
Theoretical study of electron density distribution in the nighttime equatorial ionosphere shows that linear relationships with statistically significant correlation coefficients exist between the maximum value of the ...
Linear dependence of the postsunset equatorial anomaly electron density on solar flux and its relation to the maximum prereversal E x B drift velocity through its dependence on solar flux
(American Geophysical Union, 2004-07-30)
The postsunset equatorial ionization anomaly, with maximum F layer electron density, Nemax, occurring near 2100 LT, has been found during solar maximum to be a linear function of the maximum prereversal E × B drift velocity ...
