Monitoring of Nonlinear Processes With Multiple Operating Modes Through a Novel Gaussian Mixture Variational Autoencoder Model

IEEE Access, 2020
Customized production, quality variation of raw materials and other factors make industrial processes work in multiple operating modes. In general, complex industrial processes have strong nonlinearity under each operating mode. In this paper, a Gaussian

Comparison of History Effects in Magnetization in Weakly pinned Crystals of high-$T_c$ and low-T$_c$ Superconductors [PDF]

, 2001
A comparison of the history effects in weakly pinned single crystals of a high $T_c$ YBa$_2$Cu$_3$O$_{7 - \delta}$ (for H $\parallel$ c) and a low $T_c$ Ca$_3$Rh$_4$Sn$_{13}$, which show anomalous variations in critical current density $J_c(H)$ are ...

Thermo-magnetic history effects in the vortex state of YNi_2B_2C superconductor [PDF]

, 2008
The nature of five-quadrant magnetic isotherms for is different from that for in a single crystal of YNi2B2C, pointing towards an anisotropic behaviour of the flux line lattice (FLL).

Proton pump inhibitors are not associated with an increased risk of colorectal cancer

GastroHep, Volume 2, Issue 4, Page 165-170, July 2020., 2020
Abstract Background The clinical relevance of proton pump inhibitors use as a risk factor for colorectal cancer in humans is still unclear. Aims To investigate the risk of colorectal cancer after the use of proton pump inhibitors within a linked Cancer Registry‐General Practitioner Database cohort.

Joint Data-Driven Fault Diagnosis Integrating Causality Graph With Statistical Process Monitoring for Complex Industrial Processes

IEEE Access, 2017
In this paper, an integrated fault diagnosis method is proposed to deal with fault location and propagation path identification. A causality graph is first constructed for the system according to the a priori knowledge. Afterward, a correlation index (CI)

Critical points in the Bragg glass phase of a weakly pinned crystal of Ca$_3$Rh$_4$Sn$_{13}$

, 2005
New experimental data are presented on the scan rate dependence of the magnetization hysteresis width $\Delta M(H)$ ($\propto$ critical current density $J_c(H)$) in isothermal $M-H$ scans in a weakly pinned single crystal of Ca$_3$Rh$_4$Sn$_{13}$, which ...
