广西白蜡生产失败原因剖析

广西白蜡生产失败的主要原因是，首先，年降雨量超过１５５２ｍｍ，间接或直接地引起大批白蜡虫死亡；其次，对白蜡虫具有毁灭性的白蜡虫寄生蜂不采取任何防治措施，致使种虫寄生率高达９２．９％。因此，白蜡生产遭受失败。广西气候多种多样，年降雨量、在１５５２ｍｍ以下有２２个县，发展白蜡生产是有潜力的，可逐步恢复和发展白蜡生产。

A Novel Robust Adaptive Fuzzy Controller

For a class of continuous-time nonlinear system, a novel robust adaptive fuzzy controller is proposed by using of Lyapunov method. It is proven that the control algorithm is globally stable, the output tracking-error can convergence to a domain of zero under the assumptions. As a result, the system controlled has stronger robustness for disturbance and modeling error.     

Action Research: Its Role in the University/Business Relationship

The Action Research (AR) PhD program at Monash University had its genesis in Systems Thinking and Organizational Learning. This paper discusses the role of the university in AR projects in business and the central role that AR projects can have in a Faculty's strategic positioning. The issues that have emerged in the project to date are discussed.
