A listed company s operation efficiency can be measured through evaluating the validity of its input and output process.

Since strategy flexibility and operation efficiency affect mutually,enterprises should select the most efficient reinforced approach of strategy flexibility based on external environment and internal structure character.

An Analysis on Operating Efficiency of China Civil Airports Based on Malmquist TFP Index;

The high-speed and sound development of technological SMEs rely on high operating efficiency.

Through analyzing the status of Guangzhou metro Line1and Line 2,this paper proposes a solution for improving operational efficiency by placing passenger.

Therefore, how to evaluate and improve the operational efficiency scientifically has been an important theme for the management in mutual fund.

In order to achieve successful transformation, we must find key indicators which have great influence on the operational efficiency of companies, so as to improve their performance of business management and investment, and enhance their core competitiveness in the world market.

A novel phase synchronously demodulating circuit was introduced in this paper,in which digital controlled analog switch and high power amplifier were adopted.

Together with the high power amplifier OPA548,this circuit is adopted in an angular servo system using Low speed PM synchronous motor as actuator,which makes the whole system get a more compact structure and higher precision.
