Partial Discharge Pattern Recognition of Transformers Based on the Gray-Level Co-Occurrence Matrix of Optimal Parameters - IEEE Xplore
In this paper, a transformer PD pattern recognition algorithm based on the gray-level co-occurrence matrix of optimal parameters and support vector machine (GLCMOP-SVM) is proposed. Firstly, the GLCM ...

Fast Direct Solution of Electromagnetic Scattering with Modified HODLR Solver - IEEE Xplore
An efficient fast direct solver of method of moments (MoM) is developed based on hierarchically off-diagonal low-rank (HODLR) structure. HODLR structure exploit that the off-diagonal matrices are rank ...

State-Interaction Approach for g-Matrix Calculations in TDDFT: Ground-Excited State Couplings and beyond First-Order Spin–Orbit Effects
We introduce a state-interaction approach for computing g-matrices within time-dependent density functional theory (TDDFT) and the Tamm–Dancoff approximation (TDA), applied here for the first time.

Accelerating Variable Cell Shape Molecular Dynamics with a Position-Dependent Mass Matrix | Journal of Chemical Theory and Computation - ACS Publications
A position-dependent mass matrix in molecular dynamics (MD) was introduced by Bennet (1) and further examined by Tsuchida. (2) The resulting method is called mass tensor molecular dynamics (MTMD), ...
