Occurrence of Equatorial Plasma Bubbles during Intense Magnetic Storms by Chao-Song Huang

“…The DMSP measurements show that deep ion density depletions (plasma bubbles) are generated after the interplanetary magnetic field (IMF) turns southward. The time delay between the IMF southward turning and the first DMSP detection of plasma depletions decreases with the minimum value of the IMF Bz, the maximum value of the interplanetary electric field (IEF) Ey, and the magnitude of the Dst index. …”

Energetic Electron Flux Predictions in the Near‐Earth Plasma Sheet From Solar Wind Driving by B. M. Swiger, M. W. Liemohn, N. Y. Ganushkina, S. V. Dubyagin

“…Using a recently published technique to extract information from neural networks, we determine the most important drivers impacting model prediction are VSW, VBS, and IMF BZ. SW‐magnetosphere coupling functions that include IMF clock angle, IMF BZ ULF wave power, and IMF BY have little impact in our model of electron flux in the near‐Earth plasma sheet. …”

Feature extraction of side channel signal based on EMD and difference spectrum of singular value by Yan-li YAO, Zhen WU, Jin-tao RAO, Min WANG, Zhi-bo DU

“…In order to extract feature information of side channel signal from the strong noise,the approach of signal feature extraction was proposed on account of empirical mode decomposition (EMD) and difference spectrum of singular value.Firstly,using EMD to decompose the original side channel signal,the correlation coefficient between all the intrinsic mode functions (IMF) and the original signal were calculated to find the component of biggest simi-lar characteristic.Then,to make a singular value decomposition of IMF component and corresponding difference spectrum of singular values was obtained.Finally,according to the difference spectrum,the filtered and recon-structed signal of IMF component was obtained,and the feature information of component was further extracted.The actual examples show that the method can extract characteristic information of side channel signal validly and improve the SNR and success rate of attack of signal successfully.…”
