Andrzej Janczake d, and “unpaired” denote. To understand why Mn ions can exist with many different charge states but we invariably find only Al ions with a 3+ charge, you must know the electron configuration of the respective atoms..Knowledge of both thermodynamics and kinetics is necessary to understand how ceram删除 发表于 2025-3-25 21:04:54
Andrzej Janczakize a tetrahedron and an octahedron and to see how they fit together. To understand properties such as piezoelectricity or the mechanisms of phase transformations, you must be able to visualize the crystal structure of the material. This is particularly important when we want to predict the propertiVOC 发表于 2025-3-26 01:43:29
Andrzej Janczak in glass, but there is the extra problem of how to define what is being “defective.” (What is the perfect structure of the glass?) To estimate the concentration of point defects, we should know (1) what types of defects are present and (2) how they form, which, in turn, determines (3) how many of eAltitude 发表于 2025-3-26 04:47:00

2 Neural network Wiener models,pagation method (BPS). Three other methods, i.e., backpropagation for parallel models (BPP), the sensitivity method (SM), and truncated backpropagation through time (BPTT) are used to calculate the gradient or the approximate gradient in parallel models. For the BPTT method, it is shown that the acc诱骗 发表于 2025-3-26 18:23:26
3 Neural network Hammerstein models,cy depends on impulse responses of sensitivity models and the linear dynamic model. Knowing these impulse responses, the errors of the calculation of partial derivatives of the model output w.r.t. model parameters can be evaluated. Computational complexity of the algorithms is analyzed and expressed
