As the part of natural sceneries, snow scene is a familiar natural phenomenon in the north of China. In this paper, we present a new method to render snow scene on GPU based particle system. We simulate the whirling snowflakes in the sky and the snow deposition effect. Our method processes the birth and death of snow particles via index on CPU and uses a pair of Floating Point Textures on GPU to store...
To improve the comparability of research results in fuel ethanol industries, taking the cassava-based fuel ethanol industry as a case. The emergy method was applied to analyze fuel ethanol production system, which is made up of three stages, planting, transporting and ethanol production. This approach unified organically the three system of material flow, Energy flow, money flow during the process,...
In order to assess index weighted value scientifically, the matter element were introduced into the fuzzy weighted values to set up matter element model based on fuzzy weight. In this way, the model not only holds the merit of classical matter element, but also overcomes its limitations in practice. Referring to Chinese lakes eutrophication standard, the eutrophication degree of lake is divided into...
Longmen Shan tectonic belt located in West Sichuan Plateau, which keeps the good forests outlook and provides a unique natural environment for the growth of medicinal plants because of its unique geological features. It is a area that is one of the most abundant biological diversity in China and the whole world range, and also is the one of the most concentrated area of the origin of Chinese herbal...
This paper presents the full sample Cumulative- Voting Model and Time Series Clustering Analysis Model based on the concept of balanced influence, which regulates individual stock's impact on the month effect analysis of return rates on share prices. The balanced models avoid misleading and information coverage caused by the significant fluctuations of return rate of stock at a certain time. The models...
In this paper, we present a practical method to integrate different aeronautical communication systems comprising of satellite-based, air-based and ground-based systems into one single global aeronautical network. This integrated network is a solution to the problem of saturated ATM/ATC communications in the coming years. The model of the integrated network is explored as the base to study all concerned...
Based on investigation within China, The introduction of CMD to power utilities was developed more quickly than before. And a lot of experience and useful lessons were analyzed, and by the way many ineffective or unstable apparatuses or systems for testing or monitoring were eliminated step by step. More utilities realized, that the first thing is how to realize the actual condition of power equipment...
