Efficient control of a laser welding process requires the reliable prediction of process behavior. A statistical method of field modeling, based on normalized RBFNN, can be successfully used to predict the spatiotemporal dynamics of surface optical a
ctivity in the laser welding process. In this article we demonstrate how to optimize RBFNN to maximize prediction quality. Special attention is paid to the structure of sample vectors, which represent the bridge between the field distributions in the past and future.
In this letter we try to answer those of the open questions of the Standard model which concern the appearance of families, mass protection mechanism and the Yukawa couplings - by using the approach (proposed by one of us), which suggests a new way b
eyond the Standard model. The approach has in the starting action for fermions, which carry in d(=1 +13)-dimensional space only the spin (two kinds of the spin) and interact with only spin connection and vielbein fields, the term manifesting as a mass term in d=1+3. (After making several approximations and assumptions) we connect free parameters of the approach with the experimental data and investigate a possibility that the fourth family appears at low enough energies to be observable in the new generation of accelerators.
