The Future of United States - Chinese Space Relations
In recent years the U.S. space program has been in decline, mostly due to budget cuts. Because of those reductions, NASA is struggling to fund its space exploration programs. One solution to this problem is to collaborate with other space agencies to share the cost and the knowledge gained. The Chinese have recently put a lot of effort into becoming a global space power and are willing to collaborate with other agencies in their space exploration efforts. The United States, however, is very reluctant to enter into any type of collaborative effort with the Chinese for a host of reasons. In order to gain greater insight into this issue, a survey will be conducted using the following three control groups: 1) individuals affiliated with the U.S. space program and related agencies, 2) individuals affiliated with the U.S. military and related security agencies, and 3) individuals not affiliated with either group previously mentioned. It is believed that these three groups will give a good indication of the general feelings of the United States population towards cooperating with the Chinese in spaceflight and what obstacles need to be overcome. The central research questions will focus on whether the participants believe the United States should collaborate with the Chinese, what they believe are the main objectives of the Chinese space program, and what issues need to be addressed before collaboration is possible. The author predicts that the individuals affiliated with the space program and those of the military will be diametrically opposed to one another while most of the general public will support collaboration.
Analysis and Forecast about China’s Foreign Exchange Reserves Based on Grey System
Based on the Grey correlation analysis, the paper analyzes the influencing factors which affect the foreign exchange reserves in China. It also points out the main connected factors and forecasts the foreign exchange reserves in future by using GM (1, 1) model.
A Study on Greenhouse Automatic Control System Based on Wireless Sensor Network
The system proposed in this paper collects temperature of leaves and humidity on leaves of crop. As well as greenhouse environmental information such as temperature, humidity, etc. Crop diseases, especially, have deep relationship not only with indoor environmental factors but also with humidity lasting time on leaves and temperature of leaves. Accordingly, monitoring crop itself is as important as monitoring indoor environments. Using these collected greenhouse environmental data, indoor environments can be more effectively controlled, and monitoring crop itself can contribute to improve productivity and to prevent crops from damages by blight and harmful insects. In addition, it will be possible for farmers to do control plant growth through closely studying relationship between indoor environmental information and monitored information on crop itself. Collected data can be stored to database either in server installed in greenhouse or to remote server. It is made possible to collect information and control effectively and automatically greenhouse in the site or from a remote place through web browser. System components are: temperature sensor, humidity sensor, leaf temperature sensor, leaf humidity sensor, Zigbee based wireless sensor node, relay nodes for automatic control, and data server to store greenhouse information. The system is implemented using low power wireless components, and easy to install.
