The positive real analysis problem for discrete singular systems is considered. By giving an augmented system for general discrete singular system, and using the equivalent admissibility between augmented system and original system and the character of linear matrix inequalities, a new necessary and sufficient condition for that discrete singular systems are admissible is derived. And the new admissible...
This paper presents a comparative study between Partial Least Squares (PLS) method and support vector regression (SVR) in modeling the relationship between the near infrared spectra (NIRS) and the polysaccharide contents in Cordyceps gunnii mycelia powder samples. Both of the models were optimized by selecting the suitable spectra preprocessing methods and the best modeling parameters. And then the...
Because of differences in geological structure, litho logy and weathering degree of slope, there is double-decked exist in space composing of the slope, it is also called potential sliding surface. So, the seismic behavior of slope is hard to synchronize with each other. Upper layer of the slope will produce permanent displacement, and it will decrease the stability of the slope. Permanent displacement...
