General beam-column stiffness connections and the full-welded dog skeleton connection is analyzed and compared by Nonlinear finite element analysis method (ANSYS method) and draw some conclusions.

Considering the interface slip, a nonlinear finite element analysis model is established by using finite element analysis soft-ANSYS, and gained a reasonable shearing connection coefficient.

The lifetime of free carriers in a silicon-on-insulator (SOI) rib waveguide, which is used for Raman amplification, is studied in connection with the nonlinear optical loss.
