 nonlinear operation
 The concept of a quasi-nonlinear operation regime is introduced for the first time and the boundaries of the quasi-nonlinear dynamic range of the interferometer are experimentally determined. The range of possible trajectories and their averages changed with stimulus prestretch and GWN amplitude, indicating that system properties depended on the input characteristics; i.e., a nonlinear operation. In this paper systematic numerical studies of the nonlinear operation of a waveguide distributed feedback gas laser equipped with a metal waveguide of rectangular cross section are presented. We present an approximate analysis of the nonlinear operation of the hollow slab-waveguide laser with Gaussian reflectivity profile output mirror, including gain saturation and longitudinal as well as transverse field distribution of the laser mode. An additional step involving a nonlinear operation is necessary to transform the sinusoidally modulated output of these neurons into a signal proportional to sustained eye velocity. 更多

The K-L transform has been introduced to seismic data processing for enhancement of s/nratio of seismic records. I analysis the method of characteristics classification based on the K-Ltransform and its relation to the singular value decomposition,pointing out that it fails when therecords contain very strong noises. Introducing some nonlinear transform,such as quadratic wavetransform,before performing the K-L filtering can improve the filtering procedure, which cansuppress very strong noise while keeps signal clear without serious distortion.
