It is important to quantitatively analyze the whole Internet industry and hence master its development direction clearly, which will provide regulators with reference for industry analysis, policy formulation, and policy evaluation. This article re-constructs the calculation method of traditional Prosperity Indexes, and builds up a new indicators portfolio for Internet Industry Prosperity Indexes. By calculation, the Internet Industry Coincidence Index value is 105.9. And the Leading Index and Coincidence Index are all within the up-going range, which suggests that China's Internet Industry is likely to remain in its usual fast growing state.展开更多

SinceCarl. Benz made the first threewheeled vehicle with the speed of 18 kilometers per hour, now we’ve already have the super roadster that only needs little more than three seconds accelerating from zero speed to 100 km/h. The speed of the motor vehicle development is so amazing during these 100 years. At the same time, a number of giants appear in this industry, and they created the well-known companies such as GM, Ford, Toyota, and Honda that make pivotal influence to their national economy. The main reason these companies are successful is that they make the specific segmentation of the automobile industry and proper market positioning of their brand. Now, I will take the car industry segmentation and Beatle market positioning for example.展开更多

Although multiple cameras are commonly used, whether the cameras are triggered at the same time is typically overlooked. This study measures the startup time difference between two high-speed cameras employing a proposed measuring system. A series of comparative experiments was conducted to consider the complex factors that can lead to a time difference. The system recorded the startup time differences for different combinations of two cameras at different frame rates, and thus acquired the dependence of the time difference on these factors. Suggestions are made on the basis of the experimental results.展开更多
