Power quality disturbance detection based on IEWT
Published 2023-10-01“…In order to ensure that the power quality of the active distribution network meets the requirements of users, it is of great significance to accurately obtain the power quality disturbance parameters. For the problem that the traditional empirical wavelet transform needs to manually select the number of frequency bands when analyzing unknown power quality disturbances, this paper proposes an improved empirical wavelet transform (IEWT) algorithm. …”

The implications of ionospheric disturbances for precise GNSS positioning in Greenland
Published 2022-01-01“…Next, assessing the single-frequency ionosphere-free Precise Point Positioning (PPP), we demonstrate that the model is generally unaffected by ionospheric disturbances. Hence, the model is predestined for the application by the users of single-frequency receivers in the areas of frequent ionospheric disturbances. …”

Trapped waves generated by an accelerated moving disturbance for the Whitham equation
Published 2022-06-01“…We show that in certain regimes trapped waves are spontaneously generated from rest and find that its time of escape increases with the amplitude of the disturbance in a band. Besides, when solitary waves are taken as initial data, we observe that when the moving disturbance changes its direction, the amplitude of this wave decays oscillating with time until it eventually escapes out. …”
