Ginkgolide B is in great demand worldwide on account of its extensive and excellent pharmacological effects, however, it is difficult to separate and purify ginkgolide B. In this study, ginkgolide B molecularly imprinted polymers were prepared by combining software simulation and molecular imprinting technique, and its characterization and adsorption performed evaluation were performed to understand...
In this paper, fuzzy control was used to control a vertical rotary invert-pendulum with single fulcrum due to its complex characteristics. Movable equation of the inverted pendulum was derived according to the dynamics analysis method of Lagrange. By dealing with feasible approximation for the system, an easily analytical math model was deduced. At the same time, making use of the fuzzy logical tool...
Owing to their broad applications and huge potentials, Underwater Acoustic Networks (UAN) have drawn growing interests from researchers of science, industry and government. The complex underwater environment and unique acoustic channel lead to the difference between UAN and traditional RF Ad Hoc networks. This paper studies the performances of UAN based on Dynamic Source Routing (DSR) utilizing OPNET...
China is the biggest agricultural country in the world, and agriculture continues to be the main economic activity. Itpsilas remarkable that China has been able to properly feed over one-fifth of the worldpsilas population with only one-fifteenth of the worldpsilas arable land. Therefore, China's grain production has always been concerned by the whole world. In this paper, we present the model of...
