We have studied the so-called roof collapse in soft lithography. Roof collapse is due to the adhesion between the PDMS stamp and substrate, and it may affect the quality of soft lithography. Our analysis accounts for the interactions of multiple punches and the effect of elastic mismatch between the PDMS stamp and substrate. A scaling law among the stamp(More)
The paper introduces an isolated word speech recognition system in which the speech signal is acquired in real time, Half Raised-Sine function is applied to the MFCC parameters of the audio files, and improved DTW algorithm is implemented. Experimental results show that compared the conventional DTW with the improved DTW algorithm, the latter can obtain a(More)
