Abstract:
The purpose of this study was to evaluate the preservation of cherry tomatoes and cucumber by edible film of bovine serum albumin.The weight-loss rate,rotten fruit rate,and the contents of soluble solids,vitamin C,chlorophyll and carotenoid were detected during storage at 20~25℃.The results showed that coating with the edible films was significantly effective on decreasing the loss of fruit nutrition,water-loss rate,rotten fruit rate,inhibiting respiration.The shelf life was 15 d and 10 d respectively.

This algorithm can automatically select tracking gestures by combining skin color detection with seeking maximum connected domain;it using image geometric moment to alternate the Mean-Shift vector, and can also effectively track gesture target and achieve the size of tracking window changing along with the gesture's change of size, angle and shape. The experimental results showed that the algorithm can successfully track the dynamic and deformable gestures and capture its trajectory in real time. This algorithm processes about 27 frames persecond, and can meet the real-time requirements.

Abstract:
The practical mathematic model of synchronous generator was established in the static synchronous compensator (STATCOM) of single machine infinite bus power system.Based on Hamilton energy theory,the new nonlinear controller was designed between the STATCOM which was installed in bus voltage of system and synchronous machine excitation.This controller directly uses the energy as the storage function.Compared with other nonlinear controllers,this controller has the advantage of the fast stability and the capability of quelling the disturbance.Since the nonlinear control structure retains all in this design,it does not need the linearization.The proposed STATCOM controller is more robust than linear control method.The simulation results showed that the proposed controller could faster meet generator excitation and STATCOM access point voltage transient stability than conventional PID control under the subjection to the three-phase short circuit fault.
