In recent years, the tourism industry CO2 emissions measures become a hot topic of academic research. The tourism carbon emissions' research is relatively mature in foreign scholars, but domestic scholars are lagging far behind, which is largely subject to our imperfect tourism statistical system. This paper discusses the tourism CO2 emissions measure based on the statistical coverage of China's tourism,...
According to climate, vegetation, geomorphology, the degree of the Kaschin-Beck disease and geology, hydrogeology, soil, the degree of original environmental transform as well as the difference of the disease, etc., the authors divided the east of Jilin province into three ecological environmental zones (A,B,C), compares the situation among three zones, then draws conclusions as follows: Kaschin-Beck...
A large number of uncertain problems existing in rural drinking water safety system, it is of great significances to apply Set Pair Analysis (SPA) theory to analyze and study these uncertain problems in rural drinking water safety system. This study applies SPA theory to conduct an integrated evaluation of water quality to rural drinking water safety in Ya'an City, based on classification values of...
An important issue of ant colony optimization (ACO) is how to keep the balance between the exploration in search space regions and the exploitation of the search experience gathered so far. By using a more exploitative pseudo-random-proportional selection rule, ant colony system (ACS) can obtain better results in experiments. But it is limited by finite search space. In this paper, a novel cloud-based...
We present a mobile sensor system for traffic monitoring (GSSTM), which is a typically Grid application in ShanghaiGrid to provide accurate realtime traffic status information. Several issues and challenges in GSSTM are discussed, such as Grid architecture design, data processing for traffic status estimation, storage strategy of massive data, etc. We implemented a prototype system of GSSTM and carried...
The existing vehicular sensors of taxi companies in most of cities can be used for traffic monitoring, however sensors are always set with a long sampling interval because of communication cost saving and network congestion avoidance. In this paper, we focus on the traffic data processing in vehicular sensor networks providing sparse and incomplete information. A performance evaluation study has been...
