The natural rain simulation is wildly used in computer games, 3D animation, film and advertising. Particle system is an effective method in rain simulation. However, the particle system uses randomly generated particles and particles attribute to simulate rain, but the real rain particles are often not randomly distributed. The theoretical research of probability theory and random process and practical applications show that the similar normal distribution is the most widely in the actual natural phenomenon and social phenomenon, cloud model is a powerful tool in simulation similar normal distribution, controlling the particles system generate particle and particle attributes based on the cloud mode to simulate the real rain is more realistic.

The organic integration of spatial information technologies and Mobile communication technologies can not only speed up the process of the application of spatial information, but also extend out to a new GIS application—Mobile GIS. Especially the emergence of the Android system makes more GIS applications transplanted from the desktop stand-alone to the field of Mobile GIS. This paper explores the theories and methods of Mobile terminal GIS implementation from such aspects as Android Platform architecture, Mobile GIS architecture, map data organization, application modes, and system functions implementation. And the Mobile GIS of Tianjin map based on Android system is carried out and achieved certain results.

This brings to the idea of having some tool to control students' attendance. Some universities prefer to use paper sheet for controlling attendance, whereas some universities prefer to use paper sheet for checking students' attendance and after this, fill out these information into a system manually, like Kasetsart University Si Racha Campus does. However, this is not an efficient way since there will be spent much of time for calling students names and putting marks like "presence" or "absenc

GIS and the information technologies evolve rapidly providing new tools for visitors andtourism administrators to plan the trips, market and manage the destinations. Informationtechnologies applied in tourism service widely in today’s China, while few people know exactly whatkind of information should be provide to the visitors. The paper summarizes that information abouttourism attractions, geography, transportation, social service and lodging are the information neededby visitors based on questionnaire method. GIS combined with other information technologies cantake users more continence to search tourism information. Two kinds of mode of GIS application intourism service are presented in this paper. TIS can provide tourism information for users to searchinformation and plan the trips based on GIS and internet, and VTS can provide users a remotesimulating tour experience to help the users to make decision.
