Partial Discharge Signal Denoising Based On Ceemdan‑Tqwt Method For Power Transformers, Haikun Shang, Ranzhe Zhang, Tao Huang, Wei Lin, Zixuan Zhao

Journal of Electric Power Science and Technology

In response to the phenomena of significant oscillations and incomplete noise reduction when dealing with partial discharge signals using traditional methods, a combined approach based on complete ensemble empirical mode decomposition with adaptive noise (CEEMDAN) and tunable Q-factor wavelet transform (TQWT) is adopted to denoise the PD signals. Firstly, the CEEMDAN is employed to decompose the noisy transformer PD signals into multiple intrinsic mode functions (IMF), and the correlation coefficient is utilized to assess the correlation between the IMF components and the original signal. Those with weak correlations are considered inferior IMFs. They are decomposed using TQWT. Energy proportion and …

An Estrogen Receptor Α-Derived Peptide Improves Glucose Homeostasis During Obesity, Hui Yan, Weiqi Ai, Quan Pan, Wesley A Brashear, Yong Xu, Ling He, Shaodong Guo

Faculty, Staff and Students Publications

Estrogen receptor α (ERα) plays a crucial role in regulating glucose and energy homeostasis during type 2 diabetes mellitus (T2DM). However, the underlying mechanisms remain incompletely understood. Here we find a ligand-independent effect of ERα on the regulation of glucose homeostasis. Deficiency of ERα in the liver impairs glucose homeostasis in male, female, and ovariectomized (OVX) female mice. Mechanistic studies reveal that ERα promotes hepatic insulin sensitivity by suppressing ubiquitination-induced IRS1 degradation. The ERα 1-280 domain mediates the ligand-independent effect of ERα on insulin sensitivity. Furthermore, we identify a peptide based on ERα 1-280 domain and find that ERα-derived peptide …

Ion Heating By A Fast Magnetosonic Turbulence In The Solar Corona, Sergei A. Markovskii, Bernard J. Vasquez

Faculty Publications

Observational data at heliocentric distances of tens of solar radii suggest that fast magnetosonic modes make up a considerable fraction of the solar wind fluctuations. Furthermore, this fraction appears to increase closer to the Sun. We carry out three-dimensional kinetic simulations with particle ions and fluid electrons to evaluate the proton and alpha-particle heating produced by the damping of the fast waves in the solar corona. Realistic parameters at 5 solar radii, including the fluctuation amplitude, are used. We show that, due to the cyclotron resonance, the alphas are heated preferentially perpendicularly to the magnetic field and much more strongly …

This method derives the mathematical model of the VIENNA rectifier in the dq0 coordinate system by employing local linearization techniques and state-space averaging method. It obtains the relevant transfer function matrix, namely the linearized small-signal model of the VIENNA rectifier, which is then utilized for controller design. Subsequently, the voltage loop and current loop are designed separately using frequency domain methods. The effects of various parameters on the system are analyzed in detail using frequency …
